Miscellaneous

Over time, the VAZ 2110 begins buckle the seat belt, that is, it prevents the belt from being pulled out of the spool, even when you pull it very slowly. Or in winter, the belt is hard to pull out of the coil and you have to apply great effort to buckle up.

Many owners of dozens face with two unpleasant moments when using seat belts:

Jamming the seat belts, even when you pull them out very slowly.
Tight stretching of seat belts in the cold

According to UNECE Regulation No. 14-05; 16-04, GOST R 41.14; 41.16.
Belt malfunctions (does not hold the lock, the reel lazily retracts the strap or does not fix it, etc.) cannot be eliminated by yourself! Any tampering with the design or installation of the seat belt relieves the manufacturer of the responsibility for the correct functioning of the seat belt and for injuries sustained in an accident.
Some locks, retractors, etc. specially made so that after disassembly it is no longer possible to reassemble them. But blowing compressed air- admissible;

Therefore, you do all actions with seat belts at your own peril and risk.
The author is not responsible for any damage and injury associated with intervention in the seat belts.

How seat belts work:
The coil blocker is made on the basis of a ratchet mechanism locked by a sensitive element - a pendulum with a hemispherical support or a metal ball located in a larger diameter sphere. The ball or pendulum, moving, through a system of levers, fixes the ratchet gear of the coil to the body. A handwheel disk is installed on its axis on screw slots with a small angle. When the strap is pulled out slowly, the disc only rotates with the shaft due to friction, without locking the spool. When the tape is jerked, the disk, by inertia, presses harder on the helical surface, overcomes the friction force and, moving along the screw slots, blocks the ratchet

Repair of seat belts VAZ 2110

In order to do-it-yourself seat belt reel repair need to:
Removing the seat belt reel. It is not necessary to remove the seats for this, it is enough to move them forward and tilt the backs forward.
Determine the side where the blocking device is located(usually the thicker half). You can determine this by shaking the belt near the ear, where the ball will strum, there is a blocker. Or you can completely unwind the belt, the blocker on the side where there is a plastic square on the sidewall.

Inertial coil: a - body; b - coil; c - retracting spiral spring; g - inertial mechanism; d - ball; e - control ratchet; g - blocking ratchet.

If you mistakenly disassemble the coil from the other side, where the winding spring is located, then keep in mind that the spring can cut your hands and face. Therefore, it is better not to make mistakes with the choice of the side :)

Remove the cover(you need to pull out 4 pistons). Be careful not to spill the insides! The cover must be removed in a horizontal position.

Disassembling the seat belt reel(without effort) and get to the blocking ratchet.
Nearby in a rectangular case with a foot there is a ball that blocks the belt when the reel body is tilted.

Getting to the moving parts remove thickened grease, which looks like a dry substance and only interferes with the precise operation of the blocking mechanism.
Lubricate the seat belt reel mechanism. And you need to lubricate with a lubricant that does not thicken in the cold (lithol, CV joint, fiol, motor or transmission oil won't fit). You need a frost-resistant lubricant Ciatim201 (or its equivalent), or a good Silicone Grease.

Besides, for a more precise operation of the seat belt mechanism you can bend the bracket, or rather bend the copper paw, which is affected by the ball. The fact is that due to the weight of the ball, it unbends slightly and the belt works worse and worse.
That is, it is necessary to reduce the bending angle of the copper foot so that when the coil is in a vertical position, the latch does not engage with the teeth of the coil.
We check that when the coil is tilted, the latch works.

There are opinions that you can simply throw out this block with a ball and the seat belts will work without problems, however, this latch works not only when the car is turned over, but is also an inertial mechanism and will block the belt even when hard braking or strong shaking of the body. That's why, nothing needs to be thrown out of the seat belt reel.

We collect everything in the reverse order.
Now the seat belt works perfectly in any frost.

It is an indispensable element of the car interior. It is designed to reduce the chance of injury during an accident. Rules traffic indicate the mandatory use of this device. Therefore, if for some reason it breaks, it must be repaired urgently. It is quite possible to do it yourself.

If, you can take a number of actions that will help you quickly solve this problem. Experienced auto mechanics are ready to give some advice on how to properly fix the breakdown. At the same time, it will be possible to avoid visits to a car service and additional costs.

If the belt does not come out of the socket, it is most likely jammed. To troubleshoot, you need to understand the principle of this element of the car. With such a breakdown, there is a high probability that it is the blocking mechanism that does not work correctly. Sometimes the belt may not stretch after an accident. There is a special technology how to eliminate such breakdowns.

First of all, you need to understand the safety belt triplet. Inside the lock mechanism is special element, which is responsible for committing. It looks like a ball that moves through the levers. At the same time, he clings to the gears of the coils.

Responds to pulling too fast, while blocking the ball. It is in this system that malfunctions can occur over time. In this case, the belt may not stretch or, on the contrary, be fixed in the fastened position.

Causes of the problem

There are several main reasons why the seat belt does not retract. First of all, it should be noted the banal wear of the system. Moreover, this may apply to only one of its elements, for example, seat belt pretensioners or a locking device may fail due to wear. The roller mechanism may also wear out.

Adverse weather also cause similar problems. may cause this phenomenon.

Sometimes seat belt pretensioners fail after an accident. In this case, the coil lock or the entire main mechanism may break. After an accident in many vehicles, the belt may not retract at all back into place. This is due to the operation of the squibs of the system.

If the car has been in an accident, even with smooth pulling, the mechanism may jam. Then you have to find the cause of the breakdown and fix it.

What will be required for the repair?

For the reasons mentioned above, sometimes the seat belt does not retract. What to do? The advice of experienced auto mechanics will help. First of all, you will have to disassemble the casing and remove the coil. In some models, you will have to dismantle the seats in the place where the breakdown occurred.

To do this, you need to prepare screwdrivers (flat and Phillips), as well as Their diameter must be different. You should also purchase a universal lubricant. Seats must be protected from accidental oil spills. You will also need napkins and wire.

Repairs can be simple or more complex. In some cases, you have to completely change the coil. For some machine models, you will need to prepare special tools. But self repair seat belts will help save quite a lot of money in the family budget.

coil repair

Most often performed in the coil area. To get to it, you need to remove the side panel trim. It can be fixed with clips or bolts.

To comply with safety regulations, it is necessary to remove the terminal for the negative conductor from the battery. Contacts that lead to (if possible) are also disabled. The colors of the corresponding wires are specified in the instruction manual.

These simple steps to prevent accidental triggering of the squib. Otherwise, you may be injured during the repair process.

The coil housing must be opened. Most likely, the spring of the tape return mechanism has failed. This item can be replaced. Getting it will be easier than installing it in its original place.

How to disassemble the system?

If seat belt does not pull out, you need to properly disassemble the system. On the bottom trim of the door pillar (middle), 4 bolts are unscrewed. Next, the lining is carefully dismantled.

You need to prepare a paper clip. Now you can remove the belt. On a special eye it is fixed with a paper clip. After that, you can unscrew the bolt that holds the coil. To prevent the belt from twisting, it is fixed with the same paper clip.

The coil is easily removed from the outside. The locking mechanism is located on the side where the ball will ring. Can shake the device and easily identify right direction. 4 pistons are unscrewed, the cover is removed in a horizontal position. This way you can get to the ratchet.

Frost influence

Sometimes seat belt anchor may not work due to hard frost. There is no need to change any details. In some older vehicles, the mechanism isolation may not be sufficient. This causes the belt to jam.

In this case, the oil that lubricates the system becomes thicker in the cold. You will have to disassemble the coil and lubricate its elements with a special substance. It must be frost resistant. This, for example, can be silicone grease or lithol.

In some cases, the situation can be corrected by bending at a smaller angle of the "foot" from the metal of the ball mechanism. With the coil in a vertical position, the latch should not come into contact with the teeth of the gear. This should only happen when the reel is tilted.

Replacing the coil

In some cases do-it-yourself seat belt repair requires a complete coil replacement. If, after the actions taken, the tape is still not removed from the reel, this action, most likely, cannot be avoided.

Typical indications when the coil should be replaced is no change after cleaning this system. If, after pulling it out and lubricating it with a new substance, as well as bending the metal foot, the belt still does not reach, a new mechanism must be purchased.

For each brand of car, it is necessary to select its own special type of device. Therefore, the store must show the old coil. This will allow you to choose the right mechanism.

Diagnostic device

If seat belt does not pull out, the cause of the breakdown can be shown by a high-quality autoscanner. Experts recommend purchasing high-quality devices from trusted manufacturers. This will allow you to accurately determine the cause of the presented breakdown.

In addition, the autoscanner will be able to detect many other faults. Moreover, the program can be installed on a smartphone. The use of such devices will save money. You do not need to visit specialized services and perform expensive maintenance.

Considering why seat belt does not pull out, you can replace or repair the mechanism yourself. There is no need to visit service center and pay for expensive repairs of the presented system.

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

It all started with seat belts, which "migrated" to vehicles from aviation. The first prototypes of belts appeared almost from the beginning of the automotive era. In 1903, the first version of such a security system for cars was proposed, but then it did not take root. They became more actively interested in them in the 50s of the last century. And 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 there was little use from the independent use of pillows, but in combination with belts they seriously increase safety.

Car crash test

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

Components used in construction

The main element of this tool is a tape made from polyester fibers. This material is different high rates rupture and able to withstand enormous loads. This tape forms a strap that holds the driver in a certain position and does not allow the body to lean forward when frontal collision. This, in turn, excludes the departure of a passenger from the car, a collision with the windshield, steering wheel, front panel.

In addition, the seat belt device modern models includes a number of other elements:

adjustable and non-adjustable belt attachment points;
lock;
inertial coils;
limiters;
pretensioners.

But all these elements did not appear in the design of the seat belt immediately. The history of these funds is very extensive, as evidenced by the considerable number of existing species.

Types and their features

At the same time, the difference between different types reduced only to the number of attachment points. But injury safety depends on this parameter quite strongly.

In general, seat belts by the number of attachment points are divided into:

two-;
three-;
four-;
five-;
six-point.

Note that in addition to the safety of belts, the convenience of their use is also taken into account, therefore, it is not always large quantity dots is the best option.

Two point harnesses

Point-to-point - the first option that has been massively used on cars. But this type is the most ineffective in terms of security.

On vehicles, two variations were used - waist and chest. In the first case, the belt ran across the seat in the waist area. One of the attachment points was near the threshold or at the bottom of the side pillar, while the second was installed between the seats on the central tunnel, and it included a lock. This option is bad because the strap held only the lower part of the body, and the upper one, in the event of an impact, due to inertia, strongly moved forward, that is, injuries from hitting the front panel and the steering wheel were guaranteed.

The chest version of the two-point belt ran diagonally across the chest. Such laying of the strap was provided by the upper location of the attachment point on the side rack. The fixing point with the lock remained in the same place - between the seats. In this variant, the upper part of the body was held during the accident, but due to the lack of lower fixation, there was a possibility of the body “diving” under the belt, which again caused serious injuries.

Three point type

Three-point seat belts are one of the most best options for use, as they provide proper fixation of the body and are quite comfortable to use.

The fixation of the strap in this type is carried out at three points - upper and lower on the side stand and with a lock - on the central tunnel. One of the points on the stand is the end for the strap (the end is attached to it), while the second is equipped with a reel for winding the belt. As for the tongue, with which the belt is fixed in the lock, it is movable and can move along the strap.

After pulling the strap and fixing it in the lock, one part of it is located diagonally and runs along the chest, and the second - transversely in the lumbar zone. That is, the three-point type combines both variants of the two-point version at the same time.

This positioning of the tape provides a hold on the upper body and eliminates the possibility of "diving". It is also convenient to use, because for styling it is enough just to pull the belt and fix it only at one point - with a lock.

Four point design

Straps with four attachment points are used mostly on sports cars mobiles. They did not receive distribution on mass models due to the inconvenience of use.

It is noteworthy that the attachment points in this embodiment may be different. One of the options is two vertical straps with a static one-piece fastening and one detachable strap in the lumbar area. The peculiarity of this version is that the vertical belts are not attached to the body elements, but directly to the seat.

The inconvenience of landing lies in the fact that you first need to throw vertical ribbons over your shoulders (like putting on a backpack), and then stretch and fix the lumbar belt.

The second option is different in that the vertical straps are not static and can be detached. But for this, there are fixing tongues at their ends and they are installed on a special additional lock located on the lumbar belt.

Five- and six-point views

The five-point option is also used on sports cars. Additionally, it has found application in child car seats. Essentially, this is the same four-point harness, but it has another strap. It stretches from the bottom of the seat, fits between the legs and is fixed in the lock, which is used to fasten the vertical belts. This option provides a secure hold on the body and improved load distribution across the belt.

The difference between the six-point view is that it has not one, but two belts from the bottom of the seat. Fixation of the body in five- and six-point types of seat belts is very reliable, which reduces the likelihood of injury. But at the same time, they are very inconvenient, since the passenger has to first stretch the lumbar strap, then fix the vertical ones, and then also fix one or two lower ones. Therefore, these types of belts on models mass production are not used.

Components and their purpose

Note that not all components may be included in the design of safety equipment on certain models.

fasteners

Let's start with the attachment points. Often they are installed on body elements. This is due to the fact that the human body at the moment of inertial displacement forward creates a significant load on the belt. In the case of using the attachment point built into the seat, due to a strong load, the structure may not withstand, and the backrest will move along with the body. In the case of fastening to the body, this will not happen.

But in devices with four or more points, some of them are still mounted in the seat (vertical straps). At the same time, we note that the design of the seats in sports cars is much more rigid and is designed to absorb heavy loads, which is why it is allowed to install mounts in them. But as for the fastening of the lumbar strap, it is fixed to the body.

Now about the convenience of attachment points (concerns the top ones). The straps built into the seat are comfortable as they come out over the shoulders. But the points on the counter can cause discomfort. With its high position in people of short stature, the diagonal part of the belt will pass almost along the neck, which is not only inconvenient, but also unsafe. And for tall people the low position of the top point will allow the belt to pass below the shoulder, which will restrict the movement of the arm. That's why top points Manufacturers make mountings on racks adjustable. On fasteners located on the seats, adjustment is not required.

Lock

The lock provides a detachable fastening point. It also provides the convenience of laying the straps. The operation of the lock is very simple - a hole is made on the tongue located on the belt, and a pin is used in the lock. When installing the tongue, the pin enters the hole, thereby ensuring a secure fit. To disengage, it is only necessary to press a special lock key to retract the pin and release the tongue.

Inertial coils

The effectiveness of the belts largely depends on their correct tension. Previously, for this it was necessary to adjust the length of the straps “for yourself” with special loops. This did not particularly cause problems for the driver, since it was enough for him to adjust the belt once. But passengers with different builds had to be adjusted every time.

Inertial coil mechanism

This problem has disappeared with the advent of inertial coils. It provided automatic winding of the tape so that it did not interfere. You can only pull it back with a smooth movement. It will not be possible to sharply unwind the strap with such a coil, since the mechanism blocks it during fast unwinding.

The use of an inertial coil solved several problems at once - when unfastened, the tape winds itself up, which is very convenient. Also, the coil independently adjusts the tension, choosing the excess part of the belt. Another positive quality– blocking of the coil at sharp unwinding. It does not allow the belt to unwind, so it “catches” the body, preventing it from moving forward much. But there is also a negative quality - it does not block immediately, and the length of the belt still increases slightly, which is why the body has time to pick up a slight acceleration. And that increases the chance of injury.

Limiters

Limiters allow you to slightly increase the length of the belt, but smoothly. The bottom line is this, the body experiences significant overloads during inertial deflection. If it is abruptly stopped, which is what the belt does, then injury is possible. But if the strap slightly increases its length, then this will partially extinguish the energy and increase safety.

coil torsion bar

The limiter is a torsion bar that acts as an axis for the coil. In a collision, the reel blocks the unwinding of the belt, the body rests against the belt, which creates a load on the belt. When a certain force is reached on the strap, the torsion bar begins to twist, turning the coil and unwinding the strap. Because of this, a smooth damping of the force on the belt occurs. It is worth noting that the strap itself does the same. Polyester tape can stretch a little when a significant load is placed on it.

Pretensioners

Pretensioners appeared on cars quite recently, but their role is significant. As already noted, the coil is not immediately blocked, so the body still receives acceleration. To prevent this, pretensioners are used that tighten the belt even before the body begins to inertial motion. That is, it prevents getting an acceleration. These devices work proactively and for this, impact sensors are used, which are used in the design of airbags.

The pretensioners work like this: at the moment of impact in a collision, the sensors register it and send a signal to the control unit. He, in turn, engages executive mechanisms, and they instantly tighten the tape, eliminating even the slightest shift of the body forward. There are two types of pretensioners - squib and electric.

Electric pretensioner

How does everything work?

Finally, consider full principle work of seat belts in modern cars. Let's take three-point type mechanisms as an example, since they are the most common.

So, the driver gets into the car and smoothly pulls out the tape until it is long enough to install and fix the tongue in the lock. After that, the inertial coil will select the excess, but not completely, so as not to hinder the driver's movements. If the safety device is equipped with a pretensioner, then the function of the coil is completed.

At the moment of a collision, sensors register the impact and activate the pretensioners, due to which the strap is stretched. As the force increases, the torsion bar comes into play, gradually increasing the length of the strap to absorb the force. Additionally, the belt itself is pulled out.

If there are no pretensioners, then the coil performs the function of holding the body. Sharp acceleration body leads to blocking of the coil and the straps "catch" the body. Next, the torsion bar is already involved.

New developments

Developments to improve this security feature are ongoing. The latest innovation, massively involved in the car, was the pretensioners. But they are not the latest technology.

Tapes are already being developed that also act as cushions. The bottom line is that upon impact, it is filled with gas, due to which the contact area of \u200b\u200bthe body with the strap increases, which helps to better distribute the load and reduce injury.

They also develop an electronic self-adaptive pretensioner system, depending on the use and pulling of the strap, it determines, according to the given algorithms, the weight of the passenger and, accordingly, the necessary force to hold him at the time of the accident.

Autoleek

Over time, the VAZ 2110 begins buckle the seat belt, that is, it prevents the belt from being pulled out of the spool, even when you pull it very slowly. Or in winter, the belt is hard to pull out of the reel and you have to make a lot of effort to fasten it.

Now the seat belt works perfectly in any frost.

Seat belts are one of the best means passive protection. They prevent the body from moving during impacts and collisions. Enhanced Efficiency can be achieved through cushions built into the hard parts of the cabin.

Attention! The use of seat belts in the design of the car helps to avoid a number of serious injuries.

An interesting social video about the consequences of seat belts:

Types of seat belts

Automotive industry over 100 years of constant evolution. It is not surprising that during this time many unique designs appeared. It is most convenient to classify the types of seat belts according to the number of fixation points:

point-to-point;
three-point;
four-point;
five-point;
six-point.

Now most cars have three-point harness security. They have V arrangement, thanks to which it is possible to achieve an optimal distribution of energy in a collision.

Attention! For the first time, three-point seat belts were installed by engineers Volvo. This happened in 1959. The author of the development is Niels Bohlin.

Perhaps the most famous modification of such a device is the Belt-in-Seat design. In it, the shoulder part of the latch is attached to the back. The first to introduce this technology into production were representatives Mercedes. It happened way back in 1990.

The first car to be sold in the states with BIS technology was the Mercedes-Benz SL. This is a premium car, in which the comfort of passengers and their safety at that time reached an unprecedented level.

Attention! It is believed that BIS technology helps to avoid injury when a vehicle rolls over.

Two point harnesses were created in the first place. True, a hundred years ago it was a simple rope stretched across the driver's belt. Interestingly, after such a long time, this technology is still used, however, in airplanes and for the back seats of cars.

Seat belts with four fixation points can be seen on sports cars. They provide a more secure fixation of the body and much less comfort. Nevertheless, this technology is considered very promising. True, to install the structure in a car, upper mounts are required.

Five-point harness security has also found its way into the sports entertainment industry. They are also used in child seats. In fact, this is a whole set of belts, consisting of many straps.

Attention! One belt in a five-point design goes through the legs, two through the waist, and the same number through the shoulders.

The six-point design is basically the same as the five-point design, but there is another additional seat belt that goes through the rider's legs. As a result, this is the most robust construction.

Separately, it is worth noting that technology does not stand still. New developments in the field of security are constantly being created. One of the most promising is the inflatable belt design. The principle of operation is extremely simple. As soon as an accident occurs, a special chamber is filled with gas. Due to the gas, the useful area of \u200b\u200bthe belt increases. This means that less load is created on the human body, due to a more rational distribution of mass. Also, this design provides additional protection in a side collision.

Attention! The gas cushion is built into the shoulder strap only.

In reality there is whole line interesting concepts which performed well in tests. These include Volvo SCC's criss-cross seat belt device. The 3+2 system deserves special attention. It was created by Autoliv and provides enhanced rollover protection. vehicle.

What is the seat belt made of?

The main structure of the seat belt consists of:

straps;
castle;
fastening bolts;
retractor.

For the production of straps is most often used synthetic material. The main requirement for him is high level strength. The seat belt retractor works on the basis of a ratchet mechanism. Emergency blocking occurs due to the sensitive element.

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

Device inertial belt security can be seen in the video:

Separately, you need to talk about the system responsible for the gradual tension of the tape. This is due to the flywheel. It is mounted on the axis of the coil. This is a small disk that makes the process smooth. But if an accident occurs, a jerk is formed, due to which the disk has to overcome the friction force. In parallel, there is pressure on the helical surface.

Attention! As a result of the actions described above, the disk is displaced and the ratchet is blocked.

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

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

Operating rules

At first glance, the seat belt is extremely easy to use. But there are certain nuances, the knowledge of which will allow you to use it as efficiently as possible.

First of all, do not overtighten the seat belt. Of course, this will provide a stronger fixation, but the risk of injury increases several times.

However, too little tension significantly weakens the braking effect of the seat belt device in the vehicle. There is a proven method that allows you to conduct correct setting. It is necessary to make such a tension so that you can put your hand under the belt, and there is a noticeable compression on the brush.

Attention! When setting up the device, it is necessary that you can easily reach all the controls of the car.

Do not, under any circumstances, fasten the harness in a twisted state! It won't provide right level fixation. Moreover, it will be simply inconvenient for you to drive a car.

An important rule operation is that after an accident occurs, the entire fixing device must be changed, including straps and bolts. There are several reasons for this.

Firstly, under strong tension, the tapes lose their properties and strength. Therefore, it is dangerous to continue using them. Secondly, complete replacement must be carried out every 5-10 years due to natural wear and tear.

Attention! Each brand of car is equipped with an original device for fixing the driver and passengers. Do not replace with a cheap analogue.

Operation of seat belts and airbags

As mentioned above, a pillow can only be effective in combination with braces. Moreover, if the driver is not fastened, the airbags may simply not work in the event of a collision.

The straps and the rest of the device, in fact, are one of the elements of the overall safety complex, which should save the life of the driver and passengers, as well as prevent injuries.

If you are not wearing a seat belt, the airbags can cause serious damage when deployed. The fact is that the impact force is not softened by anything, and this will make the collision very hard.

Statistics

If we take into account car statistics an accident, then a fastened shoulder strap saves in 70 percent of cases. In turn, pillows have proven their effectiveness in only 20%.

It is very important that absolutely everything in the cabin is fastened, including passengers on rear seats. The fact is that with a strong impact, an unfastened passenger will randomly move around the cabin, injuring everyone else.

The use of seat belts can greatly reduce the risk of injury in a collision. Moreover, fastened shoulder straps can save lives. There are many designs that are installed in different types machines. In most cases, manufacturers use a three-point locking system. Although more and more interesting alternatives are appearing, gradually being introduced into life.
