How to mount a car seat without isofix. Children's car seats with the ISOFIX system. ISOFIX on the front seat

the main / Terms

Many car enthusiasts facing the term ISOFIX do not know what it is and why it is necessary. In this article we will try to close this gap in knowledge. Here you will learn what isofix is \u200b\u200bin the car, why it is necessary, as well as what is its advantages and disadvantages. If you are planning to buy a car, this information will allow you to do right choice, ensure security and avoid traffic violations.

According to the rules' requirements road, Transportation of children in the passenger vehicle before it is used only with the use of special chairs. At the same time, the chairs should ensure the safety of a minor passenger at any emergency situations.

What does ISOFIX fasteners look like

Many manufacturers are engaged in the release of such devices, but the diversity of models and fastening methods has become more negative factor. The fact is that the use of various modifications of the car seat led to frequent errors during their installations. As a result, the children suffered even with minor accidents.

This was the reason for the emergence of a single international standard of rigid fastenings of children's car seats directly to the machine housing. This standard was introduced by the ISO International Institute and was called ISOFIX or ISO Fix.

In addition to ISOFIX, there are alternative standards for fastening a car seat. For example, in the US, the standard is quite popular Latch., and in Canada - UAS..

How to install an armchair with an ISOFIX fastening

Due to the simple design of the fasteners, it was possible to minimize the number of errors when installing a car seat for children. In essence, Isofix is \u200b\u200btwo brackets that are attached directly to the car body. The standard place of their installation is the space between the back and the seat of the passenger rear armchairs.

Installing a chair with ISOFIX fastening

To install the car seat, it is necessary to simply direct it from the brackets to the brackets and snap into the list of clamps. It is almost impossible to make a mistake in such operations, and the reliability of fixation is quite high.

There are also modifications of children's car seats with additional attachment points. Manufacturers argue that such models provide more high degree Child protection.

  • Modifications with retractable (telescopic) stubborn leg. Such an emphasis allows you to ensure the impossibility of moving the chair forward in front blows, however, it creates some inconvenience during operation.
  • Models with anchor mountwhich have an additional point of fixation using a special belt with a carbine. The strap bracket can be behind the head restraint of the seat or on the floor of the luggage compartment. Such a modification is considered more convenient and no less reliable. Almost all new cars are completed with the ISOFIX system specifically.

It should be noted that most of the children's car seats with the ISOFIX fastening system can also be fixed using ordinary car belts. This is useful if the chair needs to be used in a car that is not equipped with an appropriate fastening.

What are the car seats with the fastening of Isofix

Isofix fastening is used for attaching car seats designed for the weight of the child up to 18 kg. These are the so-called group 0+ and group 1.

Car seat with ISOFIX mounting of the group 0+ (left) and 1 (right)

Car seats of group 0+ used for newborns and children weighing up to 13 kg. This design is a set of two main elements - directly carrying seats (crackers) and a base having an isofix type mount. The main advantage of such modifications is the ability to conveniently endure even a sleeping child. Just put a chair on the base, pressed and the safety of the trip was provided. The minuses of such a system traditionally include increased cost, and the base, and the carrying itself have a fairly high price.

Car seats Group 1 are used for weight 9-18 kg. In essence, this is a traditional chair with a standard fastening embedded in its lower part. There are no special design differences, but simplicity allows us to provide reliable fixation and safety.

Also on sale appeared and combined car seats Groups 0 + / 1which can be used for any child weighing up to 18 kg. Such modifications can be installed both during the movement and against it. In this case, the fastening of isofix is \u200b\u200bused mainly exclusively for group 0+. Separate models have a corporate bowl system (up to 180 degrees), allowing to simplify the placement of the child or disembarking it.

Some minuses fastening isofix

The main disadvantage, as already noted, is a weight limit. If the mass of the child is more than 18 kg, it is technically impossible to ensure reliable fastening of the chair during emergency shock loads due to a certain strength of the structural elements.

Some difficulties cause and differences in the design of themselves passenger seats car. Different form of the back, head restraints, differences in size and other factors complicate the use of standard isofix fasteners.

What is better to choose - car seats with isofix or simple designs with conventional belts? The presented question is most often worried about the responsible parents who are in the search for the safest way to transport the child in the car. We will try to clarify this situation, considering the main advantages and disadvantages of the car seat with

What constitutes

ISOFIX technology corresponds to generally accepted European standards for fastening children's chairs in cars. During the installation, the latter are connected directly to the vehicle body. It disappears the need for applying to ensure the kids complete safety during movement, it suffices to fix the car seat with isofixes using a special fastener located in the rear seat.

IN last years Technology is increasingly taken by domestic manufacturers vehicles. Therefore, today such systems can be seen in basic configuration The most numerous machines.

Reliability

A car seat up to 36 kg of isofix is \u200b\u200bstill connected to a rigid car frame, providing reliable user fixation in a static position. Thus, with a sharp stop of the machine completely excluded departure children's chair In the front direction and, accordingly, the risk of injury is reduced.

Additional fixation

Users who are a little connected chairs with a car frame, are offered hard stops that provide an additional fixation of the design to the floor. The mount is a kind of "foot", which is connected to the scene at the base and limits its movement in any directions.

Easy mounting

The next advantage that is different from an isofix car seat (9-36 kg) is the lack of problems with the installation. As practice shows, the bulk of the damage that children receive in the event of an accident caused by the displacement of the seat, fixed by the basic belts.

Installation of car seat with isofixes eliminates error assumptions and as a result - incorrect triggering of elements that are responsible for safety in extreme situations. Proper installation The designs of this type can be categorized 90% of users who face similar systems for the first time. The remaining 10% of cases of incorrect installation occur on consumers who had to deal with

Driver safety

Since the sacchairs with the isofix system are automatically snapped into the attachments, the driver does not have to remember, he fastened to the children's seat before the trip or not. This moment is extremely important, since even the easiest, empty chair, which flies in the head of the car owner in the event of an accident, can cause the most serious injuries.

Design

Before moving to the disadvantages of the car seat with the system, it is worth noting that the most of them resemble capsules, which are used by the Formula 1 races, rather than design for children. In addition to the connection with the car frame, there are therefore there are therefore fixing the child occurs directly to the chair. And this contributes to the scattering of energy, which occurs in the case of sharp braking and, accordingly, reduces the load that you have to experience a young passenger.

Disadvantages of seats with ISOFIX system

Like any other products, car seats with isofixes (9-36 kg) has its own minuses:

  1. Isofix acts as hard fastening. Therefore, any serious collision causes sufficiently high loads on the cervical spine of the baby, fixed in the chair.
  2. If there is such an armchair, the motorist is forced to endure extra inconvenience if the machine is needed.
  3. If the family has several vehiclesYou have to resort to additional waste on their equipment fastening ISOFIX.
  4. Any car seat (15-36) isofix is \u200b\u200bheavier for about 25-30% of ordinary beds with belt fasteners.
  5. The obvious minus of the designs of this type is enough high price. The price of such products compared to armchairs, where there are no ISOFIX mounts, 50-60% higher. Therefore, highly reliable systems of the European sample turn out to be on the pocket not every concerned consumer.

Finally

As can be seen, the deficiencies in children with the ISOFIX system are significantly less compared to the advantages that the user receives during the operation of such structures. The most important advantage of such systems is highest level Security, which is provided by the child during transportation on the vehicle.

ISOFIX, ISOFIX Plus, Isofit, Seatfix, Kidfix, X-Fix, Latch, Top-Tether, V-Tether, "Support Leaga", anchor mount - I know these and many other terrible words! The word Isofix became so popular in itself that now almost every call to the children's car seat is accompanied by the phrase "the chair should be with ISOFIX." In this article, let's try to figure out what isofix is \u200b\u200bin children's car seats, where when and why it is applied and why.

What is ISOFIX?

Let's start with a banal. ISOFIX is a system of hard attachment of car seat to the car body. ISOFIX is an international standard for all car manufacturers and children's car seats. It minimizes the likelihood of an error when installing a car seat and improves protective properties. The main purpose, after all, is to eliminate the ability to install the chair incorrectly (up to 70% of installations occurs with errors). After all, here you just need to correctly send the brackets and snap the locks on the brackets of the opposite part in the car.

Isofix is \u200b\u200btwo salads (2 brackets) at the base of the car seat, which with the help of special rods snap around the bracket in the car located between the back and the seat car chairs. Almost always in the car places equipped with brackets for the installation of children's car seat Isofix. Located from the back on the right and left of the sofa (although there are exceptions).
To explain in detail the snap-down system and the ISOFIX device in car seats and the car will not, because On the Internet, it is full of such information, and its practical value in terms of the choice of car seats for its Chad is extremely small.

What car seats apply isofix?

Now important. Isofix is \u200b\u200ba fastening used in groups of 0+ and 1, as well as in children's car seats - combinations of these groups. Those. For children weighing up to 18 kg (about 3-3.5 years old). And only in chairs in which the child is fixed with internal straps.
EVERYTHING. List of exhaustive And, as I already wrote, hard standardized.

It is in these groups that we encounter a normal, real, power isofix, which keeps the chair and attached to the internal belts of the child. It is in car seats of groups 1 and 0+, he assumes all the energy of the strike in the event of an accident. It is here that he gives all its advantages and in the simplicity of installation and safe.



In group 0+ (children's car seats from birth to 13 kg)
Isofix is \u200b\u200bnot applied in the children's chairs themselves, representing cradle-carrying, and in special bases that some such crackers can be installed. Pluses are obvious - we transfer the baby in a light cradle, put it at home, taking off the sleeping machine. And at the same time, there is no need for a cramped salon every time "conclusions" over a regular belt to secure the car seat. They put on the base, pressed - the chair is installed. Pressed the button or pulled the handle - the chair is free and you can carry the baby home. Safety, too, is usually better.
The minus is real one - the base of Isofix costs about as much as the chair itself under it (which in turn, as a rule, is more expensive than the chair that cannot be installed on such a base). In 95% of the models, the Base of Isofix can be thrown out / sell at the end of the use of group 0+. Although there are exceptions where the base goes into group 1, but such models, especially safe in both groups, are not very much (the example of MAXI COSI PEBBLE, etc.).

In car seats of group 1 (9-18 kg) The ISOFIX brackets are usually embedded in the base of the car seat itself (in the M-shaped part).

Although there are a number of models that are simply the top, which is put on the base from the group 0+ (example - Maxi Cosi Pearl et al.).

In the combined car seats of group 0 + / 1 with the system of Isofix (Now there are more and more these) - also built into the base of the car seat itself. But since the chair can be placed both against the stroke, and along the way, then everything is more complicated. Either Isofix is \u200b\u200bused only in the group 0+ (HTS Besafe Izi Combi), or the chairs bowl can be rotated to change the installation direction (Maxi Cosi Milofix). Either generally a turning bowl is 180 degrees, including a passenger landing and disembarking (Romer Dualfix, Cybex Sirona).

What kind of "foot" or focus on the floor on the part of the car seat, which prevents the bag with potatoes in the feet in the child? And what is some anchor strap Top Tether? Maybe better without him?

Isofix is \u200b\u200bessentially a fastening of 2 points on one axis. And it is for this axis that a colossal rotational moment occurs at an accident. In this case, a large load is created on the elements of the ISOFIX system themselves and besides, there is a dangerous shift in front of the chair with a child.
Therefore, it is necessary in the third point of the support. And it happens two types.

First view -retractable focus on the floor in the form of a telescopic "leg" coming out of the base of the car seat. Removes in the floor and thus prevents the rotation and reduces the load on the brackets.

Second view - Anchor mount Top Tether. This is a special belt leaving from top of the children's car seat with a carabium at the end. This carbine is fixed for a special bracket in the car, located, most often, either in the trunk floor, or behind the head restraint of the rear car chairs. This type of fastening is considered universal, all new cars are developed with a place under Top Tether and in the near future, any car will be equipped with them.

Due to the fact that the ISOFIX fastening system assumes huge loads in the event of an accident, ECE R44 / 04 rules are strictly regulated by its application. For this reason, the chairs with the ISOFIX system cannot weigh more than 15 kg, and it can only be used until the weight of the child is 18 kg.

There are separate models that can be attached to ISOFIX without 3 points of support. For example, ROMER VERSAFIX. This is achieved at the expense of the special mobile design of the ISOFIX guides, which allows you to redirect the load down. But this method of fastening is not universal and install the chair in this way you can only make sure that your car is in the list of compatible, attached to the car seat. Justice for the sake, there is probably 95% of all cars.

What then represents "ISOFIX" in children's car seats of groups 2-3 (15-36 kg, from about 3 years)?

The word "Isofix" I wrote in quotes, because the real Isofix system, as already wrote above, does not apply to such a weight of the child at all. Here, there are all sorts of designations "Kidfix", "Sitfix", "Isofit", etc. etc., with which manufacturers emphasize that there is no ISOFIX, but a compatible method of fastening!
In groups of 2-3 (car seats 15-36 kg), the child is already fastened by a regular seat belt conducted through special guides in the car seat. Accordingly, the entire load with an accident is on full belt.
At the same time, the chair should be able to move forward, accompanying the child until the regular seat belt is triggered, providing side protection and proper belt routing during the entire braking. Those. If we secured the chair of the group 2-3 on full-fledged isofix, he would only harm. And of course, no top-tether should not be in the floor here!

Therefore, everything that is called isofixes in a group of 2-3 is simply similar in the installation method, a system that should be able to disassemble, or extend, or shift forward when loaded.

Safety improvement functions Such a system is practically not barred, except that a little limits the displacement during lateral impact. The main advantage - no need to fasten the children's car seat with a belt when we are going without a child, and it's just worth it - it is more convenient to plant and plant a passenger. Although there are more points that are not obvious on crash tests, but in life it can affect. The first is stability with sharp turns and reversal. I, for example, a sofa profile is such that without this system, the chair 2-3 is simply falling with a sharp maneuver, which clearly does not add security. Well, the second - limits the load on the child from the chair itself at the accident. So there are its advantages, it is not necessary to write off the bills for the fact that he is not powerful.

But what about children's car seats from 9 to 36 kg?

What with the so-called "transformers", or as they are often called "universal" chairs of groups 1-2-3?

The most standard customer request "I want a car seat from 9 to 36 kg with a system of Isofix".


So, today, such chairs, at least successfully passed independent tests, there is no in nature. (Update 2016.
Has already. There will be a comment further in the text.) Due to the previously described, the principal difference in the design of this ISOFIX group 1 and decorative - from groups 2-3. The first swallow was to become Romer Xtensafix, the decisive of this problem just paying for the relative rotational mobility of the guides. But there came out the problem in the other, and what happened in the plan of "hybrid" isofix, we will not know.

Often, transformers 9-36 kg with safety stands instead of belts fall under the universal trend. After all, there is everywhere written - Isofix. But the chip is that the regular belt is skipped through the table, and all the load is again on it, and isofix there again decorative, from group 2-3. Those. In the first group, he simply compensates for the inconvenience of the chair (which without it is not fixed in the car), and in group 2-3 - works, as usual. But its safety does not give its use in this group.

There are still strange examples, like inglesina Prime Miglia I-Fix. Their approach consider completely incorrect. If you carefully read the instructions, then in 1 group (9-18 kg), it is necessary to fix this baby car seat and a regular belt and isofix (i.e., it is simply not clear why the excessive action). And in group 3 - not to use it at all. It is terrible to think how many people did not read in this aforementioned, but simply put a chair on ISOFIX. And the manufacturer, if anything, nothing to say - he warned.

Now the first classic models of transformers 9-36 kg (GR.1-2-3) appear with internal straps and isofix system, which seems to work in all groups. For the most part, from not very well-known manufacturers. I am sure that this problem is technologically solvableBut would refrain from special enthusiasms about such models before the appearance of at least some official tests confirming the safety of these structures. Isofix for the sake of Isofix I, honestly, I do not understand!

Update 2016. My confidence in the technological solvability problem was correct. The first swallow - successfully passed tests Armchair Britax Roemer Advansafix 2 SICT. And more and more manufacturers begin to produce 1-2-3 chairs with power isofix and / or a decent slope. Everyone solves the problems mentioned above in their own way. Although in most cases, the decision comes down to the deepening in the area of \u200b\u200bthe priests of the child and the maximum incline of the guides for horizontal strap straps. In general, we are waiting for new successful tests. Without them, all the same, such a set of options remains risky.

For reference - there is another American version of this system - Latch. The main difference is that there are no rigid metal brackets from the car seat, and there are straps with latches at the ends. In a group of 2-3 differences with similar fasteners of the European modification, no, because It is necessary to hold only the chair.

But with a group of 1 more complicated, because Chairs with this system are not particularly sold in Europe (I suppose, the problem with the oligation of the system itself according to European standards, where everything is rigidly regulated), and therefore, we are unlikely to see independent European crash tests on such chairs. And in the US, tests with the requirements above standards are carried out only by the manufacturers themselves. Therefore, it remains to believe or do not believe the results of the tests of the manufacturers themselves. On the other hand, there are very tidy manufacturers like the same Evenflo. But the peculiarity of American chairs with their immeasurable universalism and shifting mistakes on consciousness of the consumer. I would say that these chairs are for very attentive and pedantic people.

Well, finally, a couple of common ISOFIX myths:

Myth 1. "Car seat with ISOFIX is always safer than without it."
This is not always the case. Firstly, as already understandable from this article, this statement can only be approved for 0+ car seats (0-13 kg) and 1 (9-18 kg). In groups and 3 (15-36 kg), this is not real isofix and does not affect safety. In transformer chairs, it is still either from a group of 2-3, or an unaccificed design and tests design.

But also in groups 0+ and 1, although the armchairs with Isofix most often show top scoresBut also not always and not in all models. For example, in the independent ADAC tests of ADAC 2013 at the base of one of the car seats 0+ Isofix mechanism simply unbuttoned and the chair flew forward as a projectile. And not only on the fastening method depends on the safety of a children's chair, but also from many other factors.

Myth 2. Strictly opposite. "Chairs with Isofix is \u200b\u200bmore dangerous, because Due to the rigid fastening, there is a sharper jerk and a large load on the child. And when attaching a belt, braking occurs more gradually because The belt does not work immediately and besides can stretch a little. "

This is completely incorrect. First, many tests show the opposite. Well, secondly, who is interested, let's figure it out why it is not. When a collision occurs, there is a sharp discharge of speed from the original to zero, over a short period of time. This process is very fast, but not instant, because Some time is the deformation of the car body. And this is good, because Overload from the impact does not occur instantly, with one sharp peak, which we could and not survive, and gradually. Also with a car seat inside. If it is attached to the body is not rigid, then its braking, and therefore, and the inhibition of the child fastened by the inner straps does not begin immediately. It turns out that the child extinguishes its kinetic energy for a smaller time interval than the car body, and gets a much greater peak load, which is just a danger.

For the same reason, the best safety results among chairs with belt fastening, those who have a good strap retasing.

Several conclusions.

  • ISOFIX is an excellent invention.
  • Its main advantage is to reduce the likelihood of incorrect installation.
  • ISOFIX affects safety directly in groups of 0+ and 1 and their combination, in the others - for convenience.
  • Not always even in groups 0+ and 1, the availability of ISOFIX gives advantages to safety. It all depends on the design of the chair itself. We look crash tests.
  • the search for a full-fledged isofix in the "transformers" 1-2-3 to date is a waste of time. In chairs with a table, it from group 2-3. And in chairs with strap - this is a refusal of verified and safe seats In favor of something non-existent while unknown and unkind. Update 2016.well, if I really want, the first mentioned version is. We are waiting for the rest.
  • Isofixes in groups 0+ and 1 need 3 points of support (except for single modifications). If, say, it is written about the chair that you need a Top Tether belt, and you don't have it in the car - you don't need to take this chair because it is "the best and safe in the world." Get the opposite effect for considerable money. ISOFIX for the sake of isofix is \u200b\u200bthe wrong criterion for choice.
Shooting for the headings "About everything in the world" We have in a car seat against the course for a long time - a comparative photo review with a child!
  • Child safety issues in a moving car, it seems to be enough attention, in particular, the obligatory element of the child's trip should be a special car seat. To date, their choice is quite extensive, but making it, it is worth paying attention to the method of fastening. One of possible options Is an ISOFIX fastening system, the use of which is possible in some cars.

    ISOFIX system, in which its advantages and advantages

    Fastening the children's seat in the cabin of the car can be performed in two ways:

    • using seat belts;
    • using the ISOFIX system.

    Before considering how the installation of children's seats is carried out in a car, it should be noted that only the correctly fixed child car seat will provide the necessary conditions for this. If they are implemented using seat belts, random errors are possible - the belt may turn out to be twisted, weakly stretched, missed not in that groove, etc.

    This installation of children's seats significantly reduces the protective capabilities that car seats have. Statistics say unequivocally - seventy percent of Europeans are incorrectly fixed. Avoid this allows ISOFIX system that is shown on video

    Her main dignity is to mount the car seat needed to special brackets available on the car body. As they look, shown in the photo:

    They are located under the backs of the seat, make sure that there are such fasteners in your car, quite simple - the seats have the appropriate labeling (ISOFIX) and badges. If they are not visible, then you need to check their hands between the back and pillow, these places are shown in the photo.


    Installing an ISOFIX chair

    The use of mentioned brackets allows you to securely install children's seat, thereby ensuring the safety of the child. The installation of the chair does not take much time, and the mount is made on their own, thanks to the special brackets that are shown in the photo

    A similar fastening system is simple and reliable, the child's car seat is attached directly to the body, and most importantly - a minimum is minimized when an error is installed. Additional information about ISOFIX mounting can be obtained when watching video

    Remove the car seat is also very simple - it is enough to unlock the latches.

    It should be noted that for reliability, the ISOFIX system is additionally equipped with the so-called "Anchor belt" fastening. It is located at the top of the chair and is attached to a separate bracket existing on the car, for example, as shown in the photo:

    An additional fastening at the top of the chair is achieved a decrease in the likelihood of the "nod" seat with a frontal impact. In principle, additional emphasis in the floor, which is in some models, performs the same role. With all its external bulky, the undoubted advantage of the stop will be versatility, not all cars have the opportunity to fix the "Anchor belt".

    ISOFIX car seat, disadvantages, features and limitations

    The main limitation for the operation of the armchair with the ISOFIX fastening is weight, its value should not exceed eighteen kilograms. Otherwise, loops and latches may not withstand large loads that occur when hit, and will not cope with the child's retention function.

    TO disadvantages of ISOFIX should include the absence of uniform standards extending to rear armchairs car. Therefore, ISOFIX chairs must be certified for each specific model.

    It should be noted another feature. Usually, the car seat is located in the course of the movement, but if the age of a child is less than two years, then in some cases the chair must be placed against the movement in the front seat.
    The ISOFIX system assumes that the installation of the car seat will be done with their own hands. How to implement it is shown on video

    conclusions

    ISOFIX is a special fastening system to the case of a children's car seating machine. It allows you to secure it with your own hands quickly, and avoid possible errors when used for these purposes available safety belts. This species fastenings are not only on rear seatbut also in the front too. Due to the high efficiency, ISOFIX such a system is equipped with many cars. The restriction inherent in it - use for children weighing no more than eighteen kilograms.

    ISOFIX, ISOFIX Plus, Isofit, Seatfix, Kidfix, X-Fix, Latch, Top-Tether, V-Tether, "Support Leaga", anchor mount - I know these and many other terrible words! The word Isofix became so popular in itself that now almost every call to the children's car seat is accompanied by the phrase "the chair should be with ISOFIX." In this article, let's try to figure out what isofix is \u200b\u200bin children's car seats, where when and why it is applied and why.

    What is ISOFIX?

    Let's start with a banal. ISOFIX is a system of hard attachment of car seat to the car body. ISOFIX is an international standard for all car manufacturers and children's car seats. It minimizes the likelihood of an error when installing a car seat and improves protective properties. The main purpose, after all, is to eliminate the ability to install the chair incorrectly (up to 70% of installations occurs with errors). After all, here you just need to correctly send the brackets and snap the locks on the brackets of the opposite part in the car.

    Isofix is \u200b\u200btwo salads (2 brackets) at the base of the car seat, which with the help of special rods are snapped around the bracket in the car located between the back and the seat of the automotive chairs. Almost always in a place of place, equipped with brackets for the installation of a children's car seat, ISOFIX are located at the right and left of the sofa (although there are exceptions).
    To explain in detail the snap-down system and the ISOFIX device in car seats and the car will not, because On the Internet, it is full of such information, and its practical value in terms of the choice of car seats for its Chad is extremely small.

    What car seats apply isofix?

    Now important. Isofix is \u200b\u200ba fastening used in groups of 0+ and 1, as well as in children's car seats - combinations of these groups. Those. For children weighing up to 18 kg (about 3-3.5 years old). And only in chairs in which the child is fixed with internal straps.
    EVERYTHING. List of exhaustive And, as I already wrote, hard standardized.

    It is in these groups that we encounter a normal, real, power isofix, which keeps the chair and attached to the internal belts of the child. It is in car seats of groups 1 and 0+, he assumes all the energy of the strike in the event of an accident. It is here that he gives all its advantages and in the simplicity of installation and safe.


    In group 0+ (children's car seats from birth to 13 kg)
    Isofix is \u200b\u200bnot applied in the children's chairs themselves, representing cradle-carrying, and in special bases that some such crackers can be installed. Pluses are obvious - we transfer the baby in a light cradle, put it at home, taking off the sleeping machine. And at the same time, there is no need for a cramped salon every time "conclusions" over a regular belt to secure the car seat. They put on the base, pressed - the chair is installed. Pressed the button or pulled the handle - the chair is free and you can carry the baby home. Safety, too, is usually better.
    The minus is real one - the base of Isofix costs about as much as the chair itself under it (which in turn, as a rule, is more expensive than the chair that cannot be installed on such a base). In 95% of the models, the Base of Isofix can be thrown out / sell at the end of the use of group 0+. Although there are exceptions where the base goes into group 1, but such models, especially safe in both groups, are not very much (the example of MAXI COSI PEBBLE, etc.).

    In car seats of group 1 (9-18 kg)The ISOFIX brackets are usually embedded in the base of the car seat itself (in the M-shaped part).

    Although there are a number of models that are simply the top, which is put on the base from the group 0+ (example - Maxi Cosi Pearl et al.).

    In the combined car seats of group 0 + / 1 with the system of Isofix (Now there are more and more these) - also built into the base of the car seat itself. But since the chair can be placed both against the stroke, and along the way, then everything is more complicated. Either Isofix is \u200b\u200bused only in the group 0+ (HTS Besafe Izi Combi), or the chairs bowl can be rotated to change the installation direction (Maxi Cosi Milofix). Either generally a turning bowl is 180 degrees, including a passenger landing and disembarking (Romer Dualfix, Cybex Sirona).

    What kind of "foot" or focus on the floor on the part of the car seat, which prevents the bag with potatoes in the feet in the child? And what is some anchor strap Top Tether? Maybe better without him?

    Isofix is \u200b\u200bessentially a fastening of 2 points on one axis. And it is for this axis that a colossal rotational moment occurs at an accident. In this case, a large load is created on the elements of the ISOFIX system themselves and besides, there is a dangerous shift in front of the chair with a child.
    Therefore, it is necessary in the third point of the support. And it happens two types.

    First view -retractable focus on the floor in the form of a telescopic "leg" coming out of the base of the car seat. Removes in the floor and thus prevents the rotation and reduces the load on the brackets.

    Second view - Anchor mount Top Tether. This is a special belt leaving from top of the children's car seat with a carabium at the end. This carbine is fixed for a special bracket in the car, located, most often, either in the trunk floor, or behind the head restraint of the rear car chairs. This type of fastening is considered universal, all new cars are developed with a place under Top Tether and in the near future, any car will be equipped with them.

    Due to the fact that the ISOFIX fastening system assumes huge loads in the event of an accident, ECE R44 / 04 rules are strictly regulated by its application. For this reason, the chairs with the ISOFIX system cannot weigh more than 15 kg, and it can only be used until the weight of the child is 18 kg.

    There are separate models that can be attached to ISOFIX without 3 points of support. For example, ROMER VERSAFIX. This is achieved at the expense of the special mobile design of the ISOFIX guides, which allows you to redirect the load down. But this method of fastening is not universal and install the chair in this way you can only make sure that your car is in the list of compatible, attached to the car seat. Justice for the sake, there is probably 95% of all cars.

    What then represents "ISOFIX" in children's car seats of groups 2-3 (15-36 kg, from about 3 years)?


    The word "Isofix" I wrote in quotes, because the real Isofix system, as already wrote above, does not apply to such a weight of the child at all. Here, there are all sorts of designations "Kidfix", "Sitfix", "Isofit", etc. etc., with which manufacturers emphasize that there is no ISOFIX, but a compatible method of fastening!
    In groups of 2-3 (car seats 15-36 kg), the child is already fastened by a regular seat belt conducted through special guides in the car seat. Accordingly, the entire load with an accident is on the regular belt.
    At the same time, the chair should be able to move forward, accompanying the child until the regular seat belt is triggered, providing side protection and proper belt routing during the entire braking. Those. If we secured the chair of the group 2-3 on full-fledged isofix, he would only harm. And of course, no top-tether should not be in the floor here!

    Therefore, everything that is called isofixes in a group of 2-3 is simply similar in the installation method, a system that should be able to disassemble, or extend, or shift forward when loaded.

    Safety improvement functions Such a system is practically not barred, except that a little limits the displacement during lateral impact. The main advantage - no need to fasten the children's car seat with a belt when we are going without a child, and it's just worth it - it is more convenient to plant and plant a passenger.

    But what about children's car seats from 9 to 36 kg?

    What with the so-called "transformers", or as they are often called "universal" chairs of groups 1-2-3?

    The most standard customer request "I want a car seat from 9 to 36 kg with a system of Isofix".


    So, today, such chairs, at least successfully passed independent tests, there is no in nature. Due to the previously described previously described difference in the design of this ISOFIX group 1 and decorative - from groups 2-3. The first swallow was to become Romer Xtensafix, the decisive of this problem just paying for the relative rotational mobility of the guides. But there came out the problem in the other, and what happened in the plan of "hybrid" isofix, we will not know.

    Often, transformers 9-36 kg with safety stands instead of belts fall under the universal trend. After all, there is everywhere written - Isofix. But the chip is that the regular belt is skipped through the table, and all the load is again on it, and isofix there again decorative, from group 2-3. Those. In the first group, he simply compensates for the inconvenience of the chair (which without it is not fixed in the car), and in group 2-3 - works, as usual. But its safety does not give its use in this group.

    There are still strange examples, like inglesina Prime Miglia I-Fix. Their approach consider completely incorrect. If you carefully read the instructions, then in 1 group (9-18 kg), it is necessary to fix this baby car seat and a regular belt and isofix (i.e., it is simply not clear why the excessive action). And in group 3 - not to use it at all. It is terrible to think how many people did not read in this aforementioned, but simply put a chair on ISOFIX. And the manufacturer, if anything, nothing to say - he warned.

    Now the first classic models of transformers 9-36 kg (GR.1-2-3) appear with internal straps and isofix system, which seems to work in all groups. For the most part, from not very well-known manufacturers. I am sure that this problem is technologically solvable, but would refrain from special enthusiasms about such models before at least some official tests confirming the safety of these structures. Isofix for the sake of Isofix I, honestly, I do not understand!

    For reference - there is another American version of this system - Latch. The main difference is that there are no rigid metal brackets from the car seat, and there are straps with latches at the ends. In a group of 2-3 differences with similar fasteners of the European modification, no, because It is necessary to hold only the chair.

    But with a group of 1 more complicated, because Chairs with this system are not particularly sold in Europe (I suppose, the problem with the oligation of the system itself according to European standards, where everything is rigidly regulated), and therefore, we are unlikely to see independent European crash tests on such chairs. And in the US, tests with the requirements above the standards are carried out only by consumer. Therefore, it remains to believe or do not believe the results of the tests of the manufacturers themselves.

    Well, finally, a couple of common ISOFIX myths:

    Myth 1. "Car seat with ISOFIX is always safer than without it."
    This is not always the case. Firstly, as already understandable from this article, this statement can only be approved for 0+ car seats (0-13 kg) and 1 (9-18 kg). In groups and 3 (15-36 kg), this is not real isofix and does not affect safety. In transformer chairs, it is still either from a group of 2-3, or an unaccificed design and tests design.

    But also in groups of 0+ and 1, although the seas with Isofix most often show the best results, but also not always and not in all models. For example, in the independent ADAC tests of ADAC 2013 at the base of one of the car seats 0+ Isofix mechanism simply unbuttoned and the chair flew forward as a projectile. And not only on the fastening method depends on the safety of a children's chair, but also from many other factors.

    Myth 2. Strictly opposite. "Chairs with Isofix is \u200b\u200bmore dangerous, because Due to the rigid fastening, there is a sharper jerk and a large load on the child. And when attaching a belt, braking occurs more gradually because The belt does not work immediately and besides can stretch a little. "

    This is completely incorrect. First, many tests show the opposite. Well, secondly, who is interested, let's figure it out why it is not. When a collision occurs, there is a sharp discharge of speed from the original to zero, over a short period of time. This process is very fast, but not instant, because Some time is the deformation of the car body. And this is good, because Overload from the impact does not occur instantly, with one sharp peak, which we could and not survive, and gradually. Also with a car seat inside. If it is attached to the body is not rigid, then its braking, and therefore, and the inhibition of the child fastened by the inner straps does not begin immediately. It turns out that the child extinguishes its kinetic energy for a smaller time interval than the car body, and gets a much greater peak load, which is just a danger.

    For the same reason, the best safety results among chairs with belt fastening, those who have a good strap retasing.

    Several conclusions.

    • ISOFIX is an excellent invention.
    • Its main advantage is to reduce the likelihood of incorrect installation.
    • ISOFIX affects safety directly in groups of 0+ and 1 and their combination, in the others - for convenience.
    • Not always even in groups 0+ and 1, the availability of ISOFIX gives advantages to safety. It all depends on the design of the chair itself. We look crash tests.
    • the search for a full-fledged isofix in the "transformers" 1-2-3 to date is a waste of time. In chairs with a table, it from group 2-3. And in chairs with strap - this is a refusal of proven and safe chairs in favor of something non-existent so far or unknown and unkind.
    • Isofixes in groups 0+ and 1 need 3 points of support (except for single modifications). If, say, it is written about the chair that you need a Top Tether belt, and you don't have it in the car - you don't need to take this chair because it is "the best and safe in the world." Get the opposite effect for considerable money. ISOFIX for the sake of isofix is \u200b\u200bthe wrong criterion for choice.
