ISOFIX (International Standards Organization Fix) is a fastening system developed by the International Organization for Standardization (ISO). The purpose of this standard is to make the installation of children's car seats fast, simple and reliable.

The main feature of the ISOFIX system is that it does not require the use of car belts for the installation of children's car seats. The chair, with the help of a pair of special built-in locks on pull-out clauses, is attached to metal hinges (anchors), which are in the seat of the car and are rigidly connected to the body.

ISOFIX - eliminates the error of the installation of the car seat.

The goal of the developers of the ISOFIX system to provide universal for all cars fastening and easy use. And the most important thing is to minimize the possibility of installing a car seat. After all, if the fixation is carried out using a seat belt, it is random, it is possible to twist, not to skip it through that groove, weakly tighten, etc., which will strongly reduce the protective functions of the car seat or, even, will reduce them to zero. European statistics show - 70-80% of parents are not correctly fixed children's seats with a three-point strap! Isofix system is deprived of these shortcomings. And because the main feature of the car seat with such a fastening is that they can be fixed either correctly either.

ISOFIX - safe mount.

Armchairs Equipped with ISOFIX are tightly attached to the car body, which makes the seat more stable in the process of collision.

There is an erroneous opinion that such a tough attachment is dangerous for a child. And, allegedly, armchairs with belt fixation are less traumatic, due to the free move until the car belt is completely tensioning. Numerous experiments refute this theory. In particular, the crash tests with a new generation of Hybrid III mannequins have shown that the ISOFIX chairs provide significantly smaller loads on the neck. This is a consequence of the rule for long known specialists in the field passive security: The more stable the seat in the process of the collision, the faster the retaining systems begin to act, the better passengers are protected. In addition, the inner belts of the car seat (which is held by the child) is designed with such a calculation so that the inertia of the kid's movement is absorbed at their own elastic deformation and therefore, in general, the entire security system of the child is quite elastic.

Where is ISOFIX?

Before you buy an armchair with Isofix, you need to make sure that the appropriate attachment in the car. ISOFIX loops for which attached baby car seat, are situated in passenger seats The car, with the front side, in the slot between the pillow and the back. It is enough just to squeeze the hand there to grope them.

In some models of machines, loops can be hidden with decorative plugs. Usually, the presence of the appropriate attachment is denoted by a round icon where the child is depicted in the car seat.

Restrictions and disadvantages of the ISOFIX system.

Basic isofix restriction - The weight of a child who cannot exceed 18 kg. This is due to the fact that with hard impact on the loops and other parts of the system there are huge loads, and their strength is not limitless. Therefore, ISOFIX equip the seats of group 0 and 1, and in older chairs the system no longer performs retaining functions, and serves only for comfort. In addition, according to the ECE R 44/04 standard, the mass of the car seat with ISOFIX should not be more than 15 kg.

Another disadvantage is the existence of the problem of "non-consistency." Although ISOFIX fastening itself is standardized, there are no uniform standards for rear seats car (their height, cushion inclination angle, etc.). That is why the seats with ISOFIX must be checked and approved for each specific model.

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 the basic configuration of 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.

What is ISOFIX fastening?

At the time of writing this article, there are three main officially approved method for fastening children's car seats:

• using regular seat belts;
• ISOFIX - system approved in Europe;
• Latch is an American analogue.

As we have already written earlier on our car portal site, according to the rules Road Children with growth up to 135-150 cm should be transported only with the use of special retaining devices - which it is not said in traffic rules, but it must comply with growth and weight.

For non-compliance with these requirements, the driver risks, at the best case, to get under the COAP article 12.23 part 3 - 3 thousand rubles, and at worst - to pay the health of children. Based on this, drivers are forced to buy retaining devices.

It must be said that the range is quite wide:

• adapters on a regular safety belt (such as domestic "fes") - stand around 400-500 rubles, but, as practice shows, in emergency situations the sense of them is no;
• car seats - the price spread of the widest, you can buy a chair both over and a half thousand rubles produced by an unknown Chinese company, and the samples tested by all possible institutions for 30-40 thousand;
• boosters - the seat without a back, which lifts the child and it can be fastened with a regular belt, are suitable for older age.

The optimal choice is a full-fledged car seat with ISOFIX fastening system and five-point safety belts.

What is ISOFIX - try to figure out.

Fastening isofix

This system was developed even in the early 1990s. Nothing particularly difficult of herself it does not represent - metal brackets that are tightly attached to the body. Already judging by the name in which the ISO prefix is \u200b\u200bpresent (Organization), you can guess that the system is approved by international standards.

It should be equipped with all cars that are manufactured or shipped to the European Union markets. This requirement entered into force in 2006. In Russia, unfortunately, no such initiatives are observed, but all modern cars have one or another fasteners system for children's retaining devices.

Usually, ISOFIX loops can be found on the back row of the seats, for this you need to lift the backs of the back. For easier finding on them, decorative plastic plugs with a schematic image are put on. In any case, the instructions for the car should be indicated whether these staples are available.

In addition, buying a children's holding device of a specific category - We have already written on our site categories. We must make sure that it is also equipped with ISOFIX fasteners. If it is, it is properly fastening the chair will not be difficult: in the rear bottom of the chair there are special metal stalls with a lock, which come into engaging with hinges. For beauty and ease of use on these metal elements, plastic guide tabs are worn.

According to statistics, 60-70 percent drivers do not know how to properly attach the chair, which is why various incidents occur:

• refurbing belts;
• the child constantly slides from his own place;
• the belt is tightened too much or weak.

It is clear that in the case of an accident, such errors will cost very expensive. ISOFIX also helps to completely avoid mistakes. For reliability, car seats can be additionally secured with a strap that throws over the back of the seating and engages for the brackets. Please note that in some models, ISOFIX can be both in the rear seats and on the front right of the passenger seat.

American analogue - Latch - Made by the same scheme. The only difference is in the fasteners on the chair itself, they are not metal strings, but a carabine strap, thanks to which the hitch turns out more elastic, although not so tough, and more time is required to install.

Of the minuses, ISOFIX can be allocated:

• restrictions on the weight of the child - the brackets do not maintain a mass of more than 18 kg and can be broken;
• restrictions on the weight of the chair - no more than 15 kg.

If you make simple measurements using the first and second laws of Newton, you can see that with a sharp stop at a speed of 50-60 km / h, the mass of any subject increases 30 times, that is, on the brackets at the time of the collision there will be a mass of approximately 900 kg. .

ISOFIX children's fastening system has won great popularity among motorists.

In most cases, it is compatible with other Latch, X-Fix, SeatFix, V-Tether, Top-Tether, but also has its own design features.

In which machines there is an ISOFIX system - the history of its introduction

The International Organization of Standardization In the 90th year of the last century introduced a single ISO standard for the fixation system (fastening) of the ISOFIX children's car seat. These standards were reflected in the editorial board of ECE R-44 in 1995 and, starting from the 96th year, in European countries it became mandatory to enter the car rigidly connected with the bodies of the auto fastening staples, located at a distance of 280 millimeters, to those developed from this year. Cars.

These connectors should be located between the rear seat pillow and the back, designate the inscription "ISOFIX" and the image of the cradle. Since 2011, the rules have become mandatory for all cars sold and manufactured in the European Union.

What is the fastening of Isofix and its design features

To ensure the possibility of attaching an ISOFIX car seat design of a car seat chairs should provide for the presence of two metal brackets placed at a standard distance from each other. This fastener is included in basic complete set motor vehiclesmanufactured since 2006. Fastening sites are usually indicated by the inscription ISOFIX.

As a rule, the fastening of Isofix is \u200b\u200bequipped with two rear extreme seats, on some cars they are on all seats.

In any case, before buying a car seat, you should carefully examine all the seats, as they can be placed hidden, and can not always be denoted by the relevant information signs, especially in cases where the upholstery of the chairs changed.

In some models of cars, these can be buttons with pictograms.

In children's car seats, elements of fastening of isofixes can be located on different sides. Before buying a car seat with an ISOFIX fastening, you need to get acquainted how it will be located in the car.

Options are possible using additional structural elements. These can be options for the "stop in the floor" or Top Tether, "anchor" fasteners.

"Anchor" Top Tether fasteners assumes the presence of an additional fastening element (brackets). Sometimes it is located in the region of the trunk, the backs of the seats, even on the ceiling. The brackets are located secretly, they can be found according to the appropriate notation with the "Anchor" icon.

Option "Pop floor" is more versatile and reliable. First, some cars are not equipped with additional braces for an anchor option. Secondly, the presence of an additional stop in the floor increases the reliability of the structure, reduces the ability to overturn the structure in a collision.

Sometimes additional emphasis can be purchased separately. It has adjustment in height, since various seats have different landing heights.

Features of application

ISOFIX is used in children's car seats 0+, 1 and 2/3 groups. When serving children weighing from 15 to 36 kg, such a mount is an auxiliary means. The main load at the same time should be provided with regular car safety belts.

Safety belts in car seats are missing. A child is fastened by a regular car seat belt system.

It would seem why then use an ISOFIX fastening in this group? The fact is that when hitting the side, it significantly reduces the side displacement of the child. With a frontal collision, the children's car seat moves along the fastening of Isofix, accompanying the child up to the start of the triggering of regular safety belts, providing a "circular protection" of the child.

In group 0+, ISOFIX is a two-component system consisting of a base on which the main elements of fastening and cradle-carrying are located. These two components can be purchased separately if the design elements are standardized. In some models, when switching a child from one weight category to another, you can not change the basic system (for example, Maxi-COSI).

The base can be performed in various versions.

It is very convenient for parents of babies. The cradle is usually small in size and mass. In it, you can, without waking up a child, bring it into the car and, accordingly, pick up from it without performing complex fasteners.

A feature of the design of 0 and 1 group is that ISOFIX has built-in seat belts. Fastening with regular car seat belts is not required. This imposes 100% responsibility to the ISOFIX construction and, above all, on:

• mechanical mounting to regular car brackets;
• construction of fixing base-cradle;
• reliability of built-in seat belts;
• strength of stop.

Therefore, to acquire a children's car seat should only have proven official manufacturers and dealers. The "left" car seat can reduce the degree of child protection.

In children's systems 0 + / 1, it is sometimes used a more convenient swivel bowl, since more older children prefer the front location of the inspection area, while for parents it is more convenient to care for child care.

The presence of the 3rd point of the support is mandatory for group 1 according to the ECE R44 / 04 rules, since there are tremendous efforts during the frontal impact of the car seat. In some designs, for example, Romer Versafix, an additional support is missing.

This is compensated by a special moving design that redirects the strength of the downward down, that is, stable design Car seat. But it is impossible to install such a children's car seat for all cars equipped with ISOFIX system.

You must familiarize yourself with the instructions attached to the ROMER VERSAFIX, which provides a list of compatible auto models. In general, it should be carefully taken to buying a children's car seat, its compatibility with the design of the car, as the question is about the safety of your child.

Other Analogs

American analogue ISOFIX - Latch system. In the car there are brackets for attaching a car seat. In the children's chair there are straps with carbines, which are fastened to brackets.

Thus, the main difference of the Latch system is a moving belt connection with a children's car seat. More high degree Mobility during the collision increases the likelihood of the side displacement of the child, respectively, injury.

In practice, it is more convenient when installing and removing, when small shuffles Due to mobility compensates for accelerator load.

In Canada, use the UAS standard (Universal Anchorage System), otherwise Canfix. It is also compatible with the ISOFIX system, but has a greater than the European degree of mobility.

Advantages and disadvantages of ISOFIX fastening

The advantages of the system include:

• baby car seat is mechanically connected to the car body, and not with its seat;
• simplicity and definition of fastening to body elements of the car design;
• minimizing car seat offset with lateral impact;
• full compliance with modern safety standards.

Disadvantages (rather, minuses) of the system;

• higher cost compared to other systems;
• the ability to install only on cars equipped with appropriate mounting brackets;
• on some models, the installation of the ISOFIX chairs is difficult.

conclusions

1. If your car is equipped with ISOFIX brackets, the children's chair unambiguously should be compatible with this system.
2. Before buying a specific model of a children's chair, carefully inspect the car's salon to use the "anchor" system of fastening. Carefully read the instructions for the car seat, make sure it is compatible with your car model.
3. Provide the versatility of the use of fastening, the possibility of application for various groups, different options landing.
4. Do not acquire "left" models. Remember - it's about the safety of the baby!

Sooner or later, all parents face the problem of safe transportation of their child in the car. And here questions appear concerning the choice, reliability and installation of the car seat. What is the isofix system and how safe is the attachment?

Isofix - Reliable and necessary system for fastening children's car seats

Isofix is \u200b\u200ba system of hard attachment of a children's car seat to the car seat. It was developed by ISO - the International Organization for Standardization, the priority goal of which is to make the process of installing the chair as simple as possible and reliable.

It is worth distinguishing ISOFIX two types:

• silence, which, in fact, is intended for complete stabilization and fixation of the chair during emergency situations. It is used in categories of devices 0+ and 1;
• nestilova, used in high-class car seats.

If there is a Kidfix, Seatfix or ISIFIX designation on the device, then it means that it is a nonset ISOFIX, or rather speaking, its analogue, which, with emergency situations, can only partially slow the shift of the chair at the side impact, but not more.

When using an analogs of ISOFIX, the device for transporting a child is additionally fixed by a regular safety belt, which assumes all the load.

Unmistakable installation

Most often, it is the installation of a children's chair causes difficulties, despite the designed instructions. For example, a system covering the safety belt has such disadvantages as the skipping of it is not in that groove, twisted, weak fixation, which can reduce all protection to zero.

Studies show that about 70% of cases of car seat with the use of the belt are incorrect.

In ISOFIX system station belts Installation is not required. The chair is fastened with two polozov (brackets) with locks located in its base, to steel brackets located inside the car seat.

Most cars are equipped with brackets for ISOFIX, but before buying a device for the carriage of children is better to make sure of their availability. They are on both sides of the rear car chairs Between the seat and the back, but can be hidden with lightning or plug, which is indicated by a special symbol (image of a silhouette of a child in a car seat). Ahead isofix is \u200b\u200bnot located with the exception of individual cases (for example, independent installation), Because the rear seat is safer compared to the front.

ISOFIX to ensure maximum security and using a regular belt

The brackets to which the children's car seat is fastened, firmly welded to the car body. This allows you to maximally stabilize the device in a collision, drift and other emergency situations. Some consumers fear the fact that the rigidity of the system can harm the child. The refutation of this is various experiments. For example, the crash test with Hybrid III mannequins has demonstrated that ISOFIX reduces the pressure on the cervical department at the moment of impact.

It is no secret that the level of security in the chair in a collision directly depends on the speed of the action of the fasteners. The faster it stabilizes, the more reliable will be protected by the kid. The rigidity of the external mounts is leveled (comes down) with the help of belts of the car seat, calculated for it. ISOFIX can only harm if it is consolidated by the category 2 and 3 device, which will exceed permissible weight and lead to an exorbitant increase in the load on the system.

Also reduced load on the brackets and the entire system as a whole is carried out using additional points of support. There are two types:

• retractable foot, which is located at the base of the chair and, if necessary, is installed on the floor of the car;
• anchor Top Tether, which is a belt with a Carabin castle at the end mounted on the back of the car seat. He is attached to the hook, welded in the trunk or behind the head restraint rear seat. This anchor mount is universally and provided in most cars.

Minuses of ISOFIX system

1. In groups 2 and 3, ISOFIX is used simply for convenience, not carrying a protective function in emergency situations, since in this case they perform their safety belt, and the system only provides additional fixation. It applies only in the agent category 0+ and 1, or on the chairs where these are combined:
   • in a group of 0+, the pollean is embedded in a special base that the cradle against the movement of the car is installed and is automatically fixed;
   • in a group of 1, it is built into the lower part of the chair or also to the database.
2. The weight of the child should not exceed 18 kilograms, also the standard ECE R 44/04 limits the mass of the chair itself to 15 kilograms. This is explained by the fact that with strong blows to the system are colossal loads, and its strength is still not limitless.
3. The equipment of the ISOFIX system takes the chair by 25-30% of its initial weight. The cost of the product is increased by about 1.5 times.
4. Since uniform standards of the rear seat of the car are not developed, when choosing a children's car seat, it is necessary to check whether it is suitable for your machine, whether the angle of inclination and height coincides.

How to install and remove car seats: instructions, photos and videos

1. Determine the location of the bracket on the car seat, if necessary, install plastic expansion on them to avoid damage to the car seat upholstery.
2. Pull the brackets from car seats, install it on the car seat.
3. Connect brackets with brackets, moved the seat close to the seat back. It should be heard a characteristic click, which indicates that the locks snapped.
4. Determine where there is a bracket for an anchor TOP TETHER (in the trunk or behind the head restraint), snap the carbine.
5. Check how reliably everything is fixed.
6. To remove the car seat, just unlock the locks.

Where and how to fix it yourself

ISOFIX system in the car can:

• installed by the manufacturer;
• provided as an additional option;
• absent.

In the second case, it is necessary to purchase parts for installation and consolidate them independently or entrust it with an experienced auto show.

Is it possible to make a loop of Isofix do it yourself

But even if you have a car of an old sample and no mounts under the ISOFIX in it are not provided, you can make them with your own hands. However, in this case, to predict how the chair will behave at the accident, it is impossible, all responsibility for the health of the child completely lies on their parents.

Opinions about whether it is necessary to put homemade isofix in the car

To put a self-mounted fastening of isofix? Buy a better ordinary chair that is attached to a regular belt.

https://www.u-mama.ru/forum/hobby/auto/635027/index.html

As I understand it, put the difficulty there is no - you apply to the body, you make marks in the places of fasteners, drill. You put the bolts from the inside and outside the nuts. Nuts - with large washers and germetom, and bolts are not from Omm - and there will be happiness.

Yura 80.

It can be attached simultaneously with the belt and isofix, personally made this (1 category). But the fact is that when the child matches him, he will have to be attached to the belt itself, and the chair under it will be clogged. My opinion personally, it's better if the chair will be fixed on the "home-made" Isofix, which will just hang out under the child, and in addition to this, the child will be fixed by the belt.
