Upon further inspection, you will find that the plastic shaft is connected to the metal stem that extends from the coil. In one part of the shaft there is a hole for mounting on the stem, on the other side there is a small hole that looks like an eyelet on a regular needle. To turn the shaft and assemble the entire mechanism into place, a piece of metal wire or a thin knitting needle must be threaded into this very eyelet. The shaft turns counterclockwise until it stops, support the mechanism with a screwdriver and wrench.
Now you can wind the belt around the shaft and remove the wire, this way the two halves of the mechanism will connect and the cover will snap into place.

There are other causes of failure when the belt does not retract or extend, some of which can be resolved without replacing the spring or major parts. For example, on many VAZ models, especially the tenth family, due to insufficient insulation, the mechanism begins to jam in frosty weather. Most often, this is not caused by breakage, but by thickening of the grease, which is not resistant to subzero temperatures. When disassembling the coil, it is necessary to additionally lubricate the mechanism with frost-resistant grease such as Litola or silicone.
Sometimes, for better stretching and retraction of the belt, it is enough to reduce the bend angle of the metal “foot”, which is acted upon by the ball mechanism. If the reel is standing upright, then the retainer should not cling to the gear teeth, but should only be triggered when the tape reel is tilted. In case of more serious malfunctions, it is recommended to replace the coil with a new one from the same car model.
Do you still think that car diagnostics is difficult?
If you are reading these lines, then you have an interest in doing something yourself in the car and really save because you already know that:
STO lomat big money for simple computer diagnostics
To find out the error, you need to go to the specialists
Simple wrenches work in the services, but you can't find a good specialist
And of course you are tired of throwing money away, and there is no question of driving around the service station all the time, then you need a simple ELM327 AUTOSSCANER that connects to any car and through a regular smartphone you will always find a problem, pay off CHECK and save a lot.
We have tested this scanner ourselves on different machines. and it showed excellent results, now we recommend it to EVERYONE! So that you do not fall for the Chinese counterfeit, we publish here a link to the official website of the AutoScanner.
Any unit of a vehicle is not eternal and tends to break.Sometimes this is not so noticeable and may appear after some time. In other cases, such as with a seat belt, the problem will be noticed immediately. What if the seat belt won't extend? For what reasons can this happen? Learn more below.
If the seat belt does not pull out of the installation slot, it is most likely jammed. To understand what this means, first you need to understand how it works. When the belt does not stretch, this indicates a failure of the locking mechanism or that the belts were jammed as a result of an accident. But first, let's look at how it works.
Inside the blocking device there is a sensitive element, which is directly responsible for blocking, which is made in the form of a ball. This ball, moving through the system of levers, clings to the gear housing of the coils. If the belt retracts strongly and quickly, the reel's flywheel disc pushes more strongly against the helical surface, thus blocking the ball.
If the lock is jammed and cannot be turned off, then this means that over time, the security mechanism began to function incorrectly.
In such cases, the strap does not retract and cannot be disabled in any way. In such cases, even an attempt to slowly latch the element may not help - it simply jammed and does not retract anymore, it does not work.
If an element of the security system of your vehicle does not retract, the lock is jammed and cannot be disabled, there may be several reasons for this. Before we move on to how to disassemble and disconnect a belt that does not work and does not retract, let's talk about the reasons. There are not many of them, so we will not dwell on this point for a long time. Indeed, in order to repair the latch of an unfastened strap, you need to know what does not work and why. So the reasons are:
First of all, the belt usually does not retract due to wear. Rather, not specifically belt wear, but, in principle, the locking system. Also, it may not be associated with the entire system, but with one of its components. If the buckle of the unfastened strap is jammed, does not retract and you cannot turn it off, then, no doubt, the matter is in the mechanism. But if the element was not fastened, this is still half the trouble. It will be much worse if it gets stuck during operation.
The second reason is the breakdown of one or another component. As a rule, it touches not an unfastened strap, but a fastened one. If a breakdown occurs or a defect appears in the operation of one of the components, then usually this is directly related to the fastened structural elements of the system. In this case, only repairs will help you and nothing else. Well, or, of course, you can always replace the failed parts.
Another reason is blocking after an accident. Usually, the design of the strap is made in such a way that in the event of hitting a road accident, the squibs of the mechanism are triggered. In this case, the lock of the device will wedge and it is no longer possible to disable it.
Depending on the car model, the driver may receive a signal that the straps are jammed. This signal can be either sound or appear on the instrument panel. Also, the signal can be displayed on the on-board computer screen, if any. In any case, if the car is equipped with "brains", the driver will receive the appropriate signal.
One more thing about signals. The driver warning may look differently. The signal can be in the form of a loud click, which is not typical for the security system. The motorist will hear this signal even when driving with loud music. As you understand, such a signal also indicates the need to clean the belt.
Now that we have figured out the signals and reasons for blocking the fastened and unfastened strap, let's move on to the repair process.Cleaning the seat belts is one of the main tasks in this process, so we will consider this procedure separately. So what if you get a signal that the lock is jammed? How can I clean it or disable it? You will learn more about this below.
To disable the lock, if the corresponding signal appears, the entire mechanism will need to be cleaned. To do this, you need to thoroughly prepare in advance and collect all the necessary tools. so what to prepare:
Phillips screwdriver, preferably short
flat head screwdriver;
a wrench on "17", it will be more convenient to use a ring wrench;
office clothespin;
syringe with a tube;
some gasoline (fuel for lighters is optimal).
When the entire list of tools is ready, you can start repairing and cleaning.
This completes the cleaning process of the mechanism. All further assembly should be carried out in the reverse order. Do everything right, because an incorrectly assembled mechanism will cause a breakdown in the near future with regular use of the straps.
Also check in advance if all the elements of this node work correctly and move freely. If this is not the case, then the cleaning should be repeated, because what is the point in it if everything is not cleaned. Only with the right approach to such repair work can you avoid basic mistakes and carry out all the actions correctly.
If you are not sure that you can do all the steps described in this article correctly, then we recommend that you contact the service station with this question. Indeed, in the case of blocking the seat belts, everything must be done correctly, and wrong actions will only cause further breakdowns, which you are unlikely to want to face. In any case, flushing the components is not the most radical measure, because you always have time to change the mechanism.
How to properly repair your vehicle's seat belts is described in the video.
The purpose of the seat belts in a car is to protect the driver and passenger in a road accident. An accident can block devices, making it difficult for a person to detach the straps. To properly unlock the seat belts and restore them to working condition after an accident, read this article.
The main components of the belts
The need to repair and restore safety straps after blocking is relevant for almost all motorists who have ever been involved in an accident. In certain situations, the belt mechanism reacts like a traffic accident. This is either an accident and deployment of airbags, or simply a high load on the device. At such moments, the igniter built into the system is triggered. The device can also jam as a result of sudden braking.
If the straps are jammed and do not work, then they operate in accordance with the design features of the machine. In some car models, the spare part cannot be repaired and cannot be unlocked. The car owner has no other way out but to cut off the belt and install a new one instead. But in most of the vehicles, the products are subject to restoration, their mechanisms can be repaired. Often in cars, in a collision, the systems are fired with both squibs in the front seats. Therefore, if you are eating alone, and the passenger is not nearby, you should still check if the strap works.
Locking straps can happen for other reasons:
Natural wear and tear of products. After prolonged use, the strap will no longer retract. This is due to the wear of both the belt itself and the locking mechanism or one of its elements.
The strap does not retract due to low freezing temperatures or wear of the roller device.
The coil lock has broken or the main device has failed.
The strap will not retract after you detach it, or it is jammed as a result of trying to fasten it.
User zhenya0164Wende in the video offers to get acquainted with the process of unlocking the belt in the Chevrolet Aveo T300.
If the safety straps are blocked, you can repair and wedge the devices yourself.
Let's consider how to do this using a squib with a sleeve:
If, in an accident, the seat belts have worked and now they are locked, you can loosen and unlock them using a special device - a toothed rack:
Remove the mechanism and carefully disassemble the belt tensioner. Secure the spring element in place so that it does not unwind during work.
The squib device is being disassembled. After that, you can see the gear rack. Its further use is impractical, since it has already broken down. To restore working condition, install a new part that you purchased in advance. Rack racks can be different in their type, buy one that is designed for a particular car model.
After removing the gear mechanisms on the inside, you will see dirt and debris. These are the wear products of the plastic components of the device. Remove dirt.
The assembly of the mechanism is carried out in the reverse order. If the spring element is unwound too much, then the seat belt is wound with its own hand. After that, the spring is mounted on the seat.
Using the example of the Toyota Rav4 car, user zhenya0164Wende offers to get acquainted with the process of unlocking the safety strap.
If the repair of the mechanisms did not give results, then the only way out would be to replace the belt:
Using the example of a Mitsubishi Lancer car, channel v15402 offers in its video to get acquainted with the process of repairing and unlocking safety straps.
Very often, the wedging mechanism of the safety strap in the car begins to jam when the belt is pulled out of the reel, even if it is pulled very smoothly, and in the cold season it is practically impossible to fasten it on. In this article, I will show you how to make a DIY seat belt repair within ten minutes, right in the car.
To perform this type of robot you need.
Short cross twist
Straight slotted twist
Seventeen socket wrench
The clip can also be used with a clothespin
Film for protecting car seats from dirt
Knitting steel knitting needle or stiff wire
Syringe with a straw
Gasoline for refueling lighters
To remove the B-pillar cover, unscrew the four self-tapping screws with a Phillips screwdriver.
Then we take out the entire seat belt and attach it to the eyelet using a clip or a clothespin.
Using a seventeen socket wrench, remove the bolt that secures the coil and take it from the bracket. Do not allow the spool to unwind and secure the strap to the spool with a clip. It is necessary to fix it so that it is more convenient to carry out repair work.
Close up car seat film, and put the dismantled mechanism on it, you need to sit on another chair.
Next, we are looking for a lid, under which the inertial mechanism is located, for this, shake the coil and under which lid it rattles and we need it.
To remove the cover, you need to remove the four plastic caps, use a knitting needle to remove them. Using a slotted twist, remove the cover.
We remove the opened mechanism (the box contains a cylinder, a metal ball and a rocker). For the mechanism to work properly, the rocker arm should move freely along the axis and not jam anything. To check, place the mechanism in a vertical position and tilt the upper part towards the ball, the rocker arm should return to its original position, without any wedging.If, nevertheless, there is wedging, it is necessary to flush the axis of the rocker arm until it begins to rotate freely and without jamming.
Then we take out the inertial mechanism (taken out without an additional tool), it is metal and is located under a plastic gear. In the central part of the hole there is an eccentric with teeth (it is the reason for the belt jamming during pulling out), the space under it should be well cleaned. To do this, you need to pour a small amount of gasoline into the center and around the perimeter, preventing the belt from winding, then remove the clip.
Next, we take the coil in our hand so that you can hold the spring and the plastic guide with your index finger, wind the strap with the other hand, and pull it a couple of times. This procedure must be repeated two to three times. Important: do not allow the belt to reel before you put the mechanism back.
That's all the repair of the seat belt with your own hands is finished, it remains only to assemble in the reverse order, and install it in place, it is recommended to carry out the same procedure on the second mechanism for prevention.

Restoring the functionality of seat belts
I don’t know about you, but I can’t go without wearing it, I somehow feel uncomfortable, and the seat belt saved me more than once ...
After buying Hayes, he found that the passenger seat belt did not retract back onto the roller, which was very annoying, especially when you open the engine compartment, he always strove to crawl under the seat and was "lost" there.
As it turned out, after removing the belt, the tension spring flew off the retainer and simply "unwound" in the casing.
I do not describe the process of removing the belt, since it may differ slightly (for example, the number of bolts).
Figure 1 shows the side
tension block from the side of the retainer / stopper.
Figure 2 shows the side
tension block from the side
Although the spring block says "Do not disassemble", but we boldly take a tool such as a "blunt awl" or a wire with a diameter of about 4-5 mm and squeeze out three plastic retainer-rods (see red arrows in Fig. 2), be careful - the rods tend to get lost ...
Then, with a knife (preferably a thin one), we pry the entire plastic "structure" and remove it from the landing rod.
Now, the fun part (I recommend wearing gloves).
With a knife or a thin screwdriver, we very carefully bend the retaining ears, the ears themselves are very fragile - do not break (see blue arrows in Fig. 2, 3).
Turning the tension block over, remove the bottom, trying not to pull the spring out of place. I didn’t succeed and the spring (although it was weakened, but the “tension” on it was sufficient) jumped out of the clip and covered my hands with a “flower”, cutting my finger a little (this is what gloves are needed for).
After untangling and laying the spring in the cage and installing the spring tails in the clips, we close everything, fix it with “ears”. Next, we proceed to the procedure for prestressing the spring (since without prestressing, the spring does not work and there is a high probability of the tail coming out of the retainer again).
For the pre. We need the tighteners: a strong thin knife, a flat (medium-wide) screwdriver.
First, make a cut with a knife in the center of the casing opposite the central spring retainer (see Fig. 3). The slot may be small, but deep enough to wedge the latch from twisting.
Now we remove the knife, turning the tensioning block over and inserting a screwdriver into the seat of the rod, we begin to wind the spring onto the central rod, so that about half of the spring is in the "inflated" state (approximately as in Fig. 2).
Now you need either a third hand or skill (I had a small vice as a "third hand" in which a screwdriver was clamped) ... without releasing the screwdriver, turn the block over and wedge the central retainer through our pre-made slot. After that, you can remove the screwdriver.
Next, you need to install the structure in place, for landing on the rod, twist only the rod itself (while the belt itself must already be screwed onto the clip, otherwise all our pretensioning does not make sense).
Having put the structure in place, we install the fixing rods and only then we try to stretch the belt and make sure that it winds back.
Then everything is easy ... we install it in its rightful place and enjoy a safe ride ...
PS. And what if someone will come in handy ... at least they won't cut their hands ...

How to repair a seat belt yourself
The seat belt is designed to prevent dangerous movements of a person in the passenger compartment during an accident or sudden braking, and thereby reduce the likelihood and severity of injuries. When a seat belt does not work in a car, it urgently needs to be repaired or replaced, since it is dangerous to continue driving with a faulty seat belt and contrary to traffic rules ... Today we will talk about the devices of the seat belt mechanism, the reasons for the failure of the belts, how the seat belt works, and how to repair it in the event of a breakdown with our own hands.
Of course, when a seat belt breaks in your car, you can turn to a specialized service station for help, which will provide you with a high-quality repair or replacement of seat belts, but at the same time you can do it yourself. And, if you adhere to certain instructions, then everything will come out quite easily, simply, and quickly.
Among the most common reasons why a seat belt does not work in a car are the following:
The seat belt in the car does not retract due to its wear, more precisely, due to the wear of the locking system or some of its components.
The belt does not stretch due to frost or wear on the roller mechanism.
The coil lock is broken or the main mechanism is damaged.
Blocking after an accident. When the car gets into an accident, the mechanism's pyrotechnics are triggered, then the device lock is jammed, and it will not be possible to turn it off.
The belt does not retract when it is unfastened, or it is jammed when trying to buckle, even when pulled out smoothly.
The seat belt consists of a shoulder strap, a buckle, and a retractor coil. The belt strap is made of durable material, and is attached with special devices to the car body in three places: on the threshold, on the rack, and on a special rod with a lock.
As for the principle of operation of the seat belts of modern cars, everything is quite simple - a reel with a blocker based on a gear mechanism, thanks to which the reel rotates.
The gear mechanism itself is closed by means of a small pendulum with a spheroidal or ball bearing with a system of levers. If the belt is pulled out smoothly, the support rotates in conjunction with the spool gear, and if abruptly, the flywheel is blocked.
What does a jammed belt mean? Over time, the seat belt mechanism begins to wedge, that is, it does not allow the belt to be pulled out of the reel, even when you pull it very slowly, and quickly buckling up in winter becomes a real problem.
The problem is simple and can be solved in ten minutes without leaving the car.
From the passenger side I have already carried out such an operation, now I present a photo report on the repair of the driver's belt.
Tools and materials
- Phillips screwdriver, short
With a short Phillips screwdriver, unscrew the 4 self-tapping screws on the lower cover of the middle drain and remove the cover by pulling it up.
Next, we pull out the entire belt and stop it with a clothespin on the eyelet.
With a 17 key, unscrew the belt reel mounting bolt and remove it from the bracket.
Now we need a cover, under which an inertial mechanism. Usually it is thicker (in the photo it is on the left), but you can
To remove the lid, you need to remove 4 plastic caps from it - Squeeze them out with a knitting needle,
Before us opens the first mechanism of the belt (It is removed freely, with your fingers) - This is a box with a cylinder, with a ball inside, and a "rocker".
We check the rocker - is it free on the axis of rotation? Having placed the "rocker" vertically, we tilt its upper part towards the ball.
Further, the second mechanism - inertial - It is steel and is located under the plastic gear. It can be removed freely with your fingers.
In the center of the toothed hole there is an eccentric with teeth (which wedges the belt when pulled out sharply), the space under which needs to be cleaned. To do this, pour a little gasoline around the perimeter of the hole and a little to the center, keeping the belt from unwinding, remove the clothespin for a while.
We assemble the coil and put it in place in the reverse order.
Repair of seized belts toyota camry. The belts have been ignited in an accident. Belts are jammed - we repair them in this video at our own peril and risk)
What if, before starting to remove the entire locking mechanism, you notice the length of the belt, lock the spring and remove it! turn out.
Today the driver's driver was dismantled, only the spring uncoiled, I had to disassemble everything, like the author, but it was worth it. learned the device of the spring mechanism))). Also, the passenger put it on, it turned out that the tension was weak, you would have to disassemble it again and already tighten its spring.
Frankly, there are a lot of unnecessary movements. However, over time, mastery will come naturally.
I cut the video 2 times more. I assembled it a couple of times. So there are extra movements going through the roof))
Well done. Today I looked at your vidos, and quietly made my own belt, almost the same coil, there is not a big difference, but it worked out that way, thanks, helped, I still had a small spring flew out inside the plastic wheel, because of this it stalled, then I found the reason. Also, I didn’t have to disassemble completely like yours, I managed to remove that clamp that holds the gear. In short, there was almost no crap, most of the time was spent on the disassembly itself and the concept of the principle of operation, and then figured out what's what, in time your vidos helped on the little things .. Of course, I'm not particularly happy, but buying ordinary inertial belts is also needed, and this is an excellent option, by the way, who asked today everyone does not know how to solve this problem, they say new belts are needed, like this is the end, I)))). , I think I will cut the vidos when I restore the driver's belt, it was a passenger one, the one that I restored, I can also help someone.
And so, there was such a problem when restoring my car after an accident: the squib in the seat belt worked (which, by the way, helped a lot in the accident) - after which it jammed.
I heard that it was possible to somehow fix it and make it "normal", but I did not know what and how. I did not find anything similar on the Internet, basically they write that it was only for a replacement - I decided to try my luck.
Therefore, while I was picking the whole thing along the way, I photographed something on a mobile phone - maybe, who will come in handy.
The order of work is as follows:
Everything. It remains only to carry out the assembly in the reverse order.
Video (click to play).
Remember that the position of the seat belt mechanism affects its performance! Therefore, when installing it in place, check the correct operation.
