A car is a place where a person is often in danger. Therefore, modern cars are equipped with various systems and means that increase the safety of the driver and passengers. These devices include seat belts. In early versions of VAZ 2106 cars, rear belts were not installed at the factory, although fastenings were provided for them. The article describes: the purpose of rear seat belts, how to install them yourself on a VAZ 2106.

Rear seat belt function

The main purpose of seat belts (SB) is to provide reliable protection for the driver and passengers in the event of an accident. You should fasten your seat belt before you start driving, including when moving around the city. Not only the driver, but also the passengers must buckle up.

Unbelted rear passengers create an additional threat to the life of the driver and themselves in the event of emergency braking.

There are rules for using RB:

1. You cannot fasten several passengers with one seat belt;
2. It is prohibited to restrain a child sitting in the arms of a rear passenger;
3. There should be no objects between the person’s body and the belt that could
4. injure the body in emergency situations;
5. The RBs should be smooth, without twisted places, and well tensioned.

Large amounts of clothing create bulk, which reduces protection.

For the rear seats, as well as for the front ones, three-point, self-winding RBs are installed. They are mounted on the side of the body. In the middle of the rear seat there is only a two-point lap belt, the length of which can be set manually. You can install rear non-inertial RBs, but they are inconvenient to use, since they have to be wound up manually each time.

2-point

The two-point seat belt was one of the first to be installed on production vehicles (TS). The effectiveness of this type showed the least results. In total, 2 types of RB such fastening systems are provided.

In the first option, the passenger is fixed in the lumbar region transverse to the seat. One mount was located in the sill or side pillar area, and the other was located between the front seats. For the convenience of fixing the RB, the security system included a lock with a latch.

The disadvantage of the design is that the strap only held the lumbar region, and in an accident the person continued to move the upper part of the body by inertia in the direction of the steering column or panel. Thus, it is simply impossible to avoid injury, although it is possible to keep the body from flying out.

The option with a chest strap provided for the installation of fasteners on the side pillar and between the front seats. In the event of a collision, the RB guaranteed the retention of the body, but the likelihood of the person fastened slipping under the belt increased, which also contributed to the high incidence of injuries.

We change it ourselves

If the RBs experienced a shock load during an accident, they must be replaced along with the winding device. The service life of these products on the VAZ 2106 is 10 years. During operation, belts rub, fray and stretch, so it is necessary to monitor their condition. They must be clean, elastic, without damage or abrasions. If defects are found, parts should be replaced.

A set of necessary tools

To install the RB on a VAZ 2106, you need to prepare:

1. a set of keys:
2. screwdriver;
3. inertial RB;
4. fastenings;
5. fasteners.

You should buy RB in a vertical version. True, you will have to suffer a little with their installation.

How to install rear seat belts on a VAZ 2106 yourself?

A car is a place where a person is often in danger. Therefore, modern cars are equipped with various systems and means that increase the safety of the driver and passengers. These devices include seat belts. In early versions of VAZ 2106 cars, rear belts were not installed at the factory, although fastenings were provided for them. The article describes: the purpose of rear seat belts, how to install them yourself on a VAZ 2106.

Pre-tensioner element

Pretensioners began to be installed in seat belt designs several years ago, but their role should not be underestimated. As noted earlier, the reel cannot technically stop the unwinding of the belt instantly, which is why the body still manages to continue its inertial movement. It is to prevent this drawback that pretensioners were developed, tensioning the belt until the moment of a sharp stop and inertial movement of the body.

There are 2 main types of pretensioners.

1. Squib cartridges.
2. Electrically driven.

Here, the mechanical principle of operation alone is no longer sufficient. Advance tension of the belts is ensured by the activation of additional shock sensors that send a signal to the control unit, which are equipped in modern cars.

Rear seat belt function

The main purpose of seat belts (SB) is to provide reliable protection for the driver and passengers in the event of an accident. You should fasten your seat belt before you start driving, including when moving around the city. Not only the driver, but also the passengers must buckle up.

Unbelted rear passengers create an additional threat to the life of the driver and themselves in the event of emergency braking.

There are rules for using RB:

• You cannot fasten several passengers with one seat belt;
• It is prohibited to restrain a child sitting in the arms of a rear passenger;
• There should be no objects between the human body and the belt that could injure the body in emergency situations;
• The RBs should be smooth, without twisted places, and well tensioned.

Three passengers and only two seat belts. What should I do?

The back seat of the car can accommodate three passengers, both physically and in terms of traffic regulations. However, the rear seats of most cars are equipped with only two seat belts. Is it punishable or not, from the point of view of traffic rules and the Code of Administrative Offenses, for an unbelted passenger to be in a vehicle if there is no means to fasten his seat belt?

The Code of Administrative Offenses in this regard has Article 12.6, which reads: “driving a vehicle by a driver who is not wearing a seat belt, transporting passengers who are not wearing seat belts, if the design of the vehicle provides for seat belts... entails the imposition of an administrative fine...”. From the text of the article it is obvious that in order to apply a penalty in such a situation, seat belts must be provided, and if there are three passengers in the back seat, and there are only two belts, then according to the Rules only two must be fastened. The same instructions appear in paragraph 2.1.2 of the traffic rules.

The law does not provide any other guidance regarding this situation, therefore, if the traffic police officer insists that you and your passengers have committed an offense in this way, ask him to refer to any regulatory document on the basis of which he has such an opinion. He obviously cannot do this. In addition, at the moment there is objectively no service for installing additional seat belts, and this makes it impossible to fasten all passengers in the back seat even if you wish.

However, the lack of a belt for the third rear seat passenger is not only a cause for concern, but also a serious threat to the safety of vehicle occupants. When conducting crash tests to check the effectiveness of rear seat belts, the following results were obtained. The tests involved cars weighing about 1,500 tons. Dummies of an adult woman and a small child were used as models. The child's dummy was placed in a child's seat. The effects on mannequins seated in the rear seat during a frontal collision at 55 km/h were assessed. In the case where the “passengers” were not wearing seat belts, they were seriously injured as a result of the impact. The mannequins, which were properly secured with belts, were not harmed at all.

With the modern development of safety systems, rear seat belts are no less, and sometimes even more important, than the front ones, since most cars are equipped with airbags, which in the event of an accident save the driver and passenger sitting in the front seat. Passengers in the rear seat receive significant damage when they hit the front seats, and in collisions of sufficient force, even against hard parts of the car body.

Thus, you cannot be punished for not wearing an unauthorized seat belt in the back seat, but the life of an unbelted passenger is at much greater risk than if a belt was present.

Unfastened seat belt

We change it ourselves

If the RBs experienced a shock load during an accident, they must be replaced along with the winding device. The service life of these products on the VAZ 2106 is 10 years. During operation, belts rub, fray and stretch, so it is necessary to monitor their condition. They must be clean, elastic, without damage or abrasions. If defects are found, parts should be replaced.

A set of necessary tools

To install the RB on a VAZ 2106, you need to prepare:

• a set of keys:
• screwdriver;
• inertial RB;
• fastenings;
• fasteners.

You should buy RB in a vertical version. True, you will have to suffer a little with their installation.

Stages

Installing rear seat belts on a VAZ 2106 consists of the following steps:

First you need to open the trunk of the car.

Open car trunk Next, we find a suitable hole in the side wall of the VAZ 2106 body, which is provided from the factory. We drill the hole to the bolt with a “10” thread.

Enlarged hole for bolt thread

• Next, you need to insert the bolt into the hole and screw it as tightly as possible with a nut. In this case, a large washer should be placed on the cab side so that the bolt head does not cut into it.
• We put the RB coil on the bolt and secure it with two nuts: internal and external.

  
  We attach the coil to a bolt. If everything is done correctly, then there will be a factory technological hole above the coil. The strap should be threaded through this hole.

  
  RB freely exits their technical holes

• We check the functionality of the device. The strap should move freely.
• Next you need to install the rear shelf. After installation, the belt will be a little pinched and difficult to move. To release the strap, you need to make the appropriate cutouts.

  
  Slots in the shelf for RB

• The second seat belt is installed in the same way.

After installing the rear boosters, you should check their correct operation. To fasten the RB, it should be pulled out smoothly without jerking. It is necessary to ensure that it does not twist anywhere. Next, you need to insert the tongue located at the end of the strap into the lock until it clicks. Then you need to tug on the latch to make sure it is securely fastened in the lock. When moving smoothly, the strap should pull out freely without delay. When jerking, it should not move. The belt is unfastened by pressing the lock button.


Result of RB installation

Thus, the VAZ 2106 car is equipped with rear inertial seat belts that were not installed from the factory. You can optionally install a middle waist strap. This completes the installation of the rear RBs. If the straps become dirty during the operation of the car, they can be washed, but do not use chemicals (washing powders, alcohol, etc.), but after a load in the event of sudden braking, it is better to replace them with new ones.

Don't neglect the safety belt and always wear your seat belt, even if the trip is short. This will reduce the risk of life-threatening injuries. It’s no wonder that wearing a seat belt is mandatory in many countries, and failure to comply with this rule results in a fine.

Limiters

The main function of the limiter is an insignificant and smooth increase in the length of the seat belt. During emergency braking or a collision, the body continues its inertial movement, being subjected to significant overloads.

Seat belts that are not equipped with limiters instantly stop the vector of movement, injuring the chest, neck or lumbar region of a person.

A gradual and smooth increase in the length of the belt allows you to reduce the speed of inertial movement, while reducing the likelihood of injury.

The limiter has the form of a torsion bar, which acts as an axis for the coil. When triggered, the reel stops the unwinding of the belt, the body rests against the belt, creating a load on the belt.

Replacing front and rear seat belts on a VAZ 2106

If you are involved in an accident, then after it you will not only have to carry out body repairs, but also change the deployed airbags along with the belts, or only the latter, since your car may not have airbags.
But even if you have never been in an accident in your entire driving experience, seat belts (SB) can become unusable, simply wearing out and losing strength over many years of service, after which they need to be replaced with new ones. Below you will learn how to do this on a VAZ-2106 car. Content:

You will need a minimum of tools: a flat-head screwdriver and a 17mm wrench or socket wrench. Well, a new belt and its lock, of course.

Innovations in passive safety

The world's leading automakers are working every day to improve all vehicle safety systems. A relatively recent innovation is pretensioners, but they are no longer new.

Innovative belts that simultaneously serve as airbags are already being actively tested.

The essence of the system is to instantly fill the belt with gas, which allows you to increase the area of ​​contact between the belts and the body, as well as evenly distribute the load, reducing the likelihood of injury.

More expensive vehicle models in the future will be equipped with self-adaptive pretensioning systems that independently adjust to the physical parameters of the seated person. The computer calculates the required force to hold the body at the time of the accident.

The inertial block is not just screwed to the shelf, there is some kind of reinforced plate under the shelf, but this fastening is located closer to the side arch.

The second end of the inertial coil is attached as in photo 4

The latch (third point) is attached under the seat in photo 1.2 (right strap), the left strap is for the middle passenger (two-point belt)

Replacing front and rear seat belts on a VAZ 2106

If you are involved in an accident, then after it you will not only have to carry out body repairs, but also change the deployed airbags along with the belts, or only the latter, since your car may not have airbags.
But even if you have never been in an accident in your entire driving experience, seat belts (SB) can become unusable, simply wearing out and losing strength over many years of service, after which they need to be replaced with new ones. Below you will learn how to do this on a VAZ-2106 car. Content:

You will need a minimum of tools: a flat-head screwdriver and a 17mm wrench or socket wrench. Well, a new belt and its lock, of course.

Replacing front seat belts on a VAZ 2106

The diagram shows the location of the belt: number 1 is the reel, number 2 is the belt itself, 3 is the latch, and 4 is the loop.

1) Take a screwdriver and use it to carefully pry the cover on the hinge mounting bolt.

2) Remove the trim, being careful not to damage its clips.

3) Take the key and unscrew the bolt that secures the RB hinge.

4) After removing the hinge, try to put it somewhere in a visible place so that the small parts associated with it do not get lost.

5) Arm yourself with a screwdriver again and remove the cover, but this time on the coil.

6) Unscrew its mounting bolt, being careful not to lose the washer and spacer.

7) Remove the coil.

Take the new belt and install it in place of the old one.

After installation, it is important to check the smooth movement of the belt so that it can be pulled out and retracted without hindrance. If there are problems with this, you need to adjust the position of the reel so that the slot in it is horizontal in relation to the belt, and not at an angle.

You also need to check whether the reel is defective: normally, when jerking, the belt should not move, but when pulling smoothly, on the contrary, it should. If the coil does not work normally, it should be exchanged for another one at the store.

Usually, along with the belt, its lock, located between the front seats, also changes.

To replace it you should:

• Remove the cover on the mounting bolt.

• Unscrew the bolt, removing the sleeve and washer, after which the lock will be removed.
• Install a new lock.

What not to do

Many motorists are simply annoyed by buckling up, and the built-in safety system begins to constantly notify the driver about this need with an unpleasant sound signal:

1. Some people purchase special “plugs” that are installed in the seat belt buckle, thereby “deceiving” the vehicle’s computer. It is strictly not recommended to do these actions, since we are talking about your own safety. When using “plugs”, the car “thinks” that the airbag is fastened and the airbags will be guaranteed to deploy. As already noted, the airbag deployment speed exceeds 250 km/h, and such an impact force is quite enough to cause irreparable damage to health. For example, cases were recorded when the driver had every chance of surviving if the RB was used, and the cause of death was a fracture of the cervical vertebrae as a result of an airbag impact.
2. Often there are families with children who are limited to fastening a car seat. In this case, the child remains unfixed. In the event of an accident, the seat remains motionless, and the baby simply flies out of it, getting injured.
3. It is not recommended to use seat belts that show signs of deep wear or damage, since in an emergency they may not withstand extreme loads and break. If necessary, it is recommended to urgently contact a specialized service station (STS).
4. In cars intended for everyday use, there is no need to equip the seat with additional safety aids. Firstly, the necessary precautions are already provided by the manufacturer, and secondly, making changes to the design can have a detrimental effect on the safety and ability of the existing device to fully operate.

Repairing, replacing or installing a passive safety system yourself is strictly prohibited.

In conclusion, it should be noted that it is necessary to wear a seat belt always and everywhere. It doesn’t matter where exactly you plan to travel – within the city or on the highway.

Regardless of driving experience and speed limit, there is always the possibility of a sudden collision with another road user. The car has always been and will be a source of increased danger and you should not neglect the opportunity to save your life and health, given that the entire fastening procedure takes no more than 1 minute.

Nowadays, cars are equipped with a significant number of safety systems and equipment. They are aimed at preventing loss of control of the car during emergency situations (active systems) and the maximum possible reduction in injury to passengers during an accident (passive means).

It all started with seat belts, which “migrated” to vehicles from aviation. The first prototypes of belts appeared almost with the beginning of the automobile era itself. In 1903, the first version of such a car security system was proposed, but then it did not catch on. They became more actively interested in them in the 50s of the last century. Moreover, at first, belts were offered only as an option and only a little later - as standard equipment.

It is worth noting that at one time the designers tried to replace the belts with another system - airbags. But later it turned out that using airbags on their own is of little use, but in combination with belts they seriously increase safety.

In general, seat belts are one of the “oldest”, but at the same time effective means of preventing injury, that is, they belong to a passive system.

WHAT IS A SEAT BELT CONSISTED OF?

The basic design of the seat belt consists of:

• straps;
• castle;
• fastening bolts;
• retractor device.

For the production of straps, synthetic material is most often used. The main requirement for it is a high level of strength. The seat belt retractor operates using a ratcheting mechanism. Emergency blocking occurs due to the sensitive element.

The basis of the sensitive element is a simple metal ball. When it moves, the reel is fixed by a system of levers. Some designs use a pendulum instead of a ball.

Separately, we need to talk about the system responsible for the gradual tension of the tape. This happens thanks to the flywheel. It is mounted on the spool axis. This is a small disk that ensures a smooth process. But if an accident occurs, a jerk is formed, due to which the disk has to overcome the friction force. At the same time, pressure arises on the screw surface.

The seat belt device helps ensure the safety of passengers during collisions. But even they have a certain limit of effectiveness. At speeds over 200 kilometers per hour, the belts will be of little use.

The bolts in the seat belt device are responsible for reliable fastening of the entire structure while driving. They are made of hard alloy that can withstand heavy loads. Moreover, they are attached to the car frame to ensure maximum reliability.
