It is sometimes believed that the main safety in a car is provided by airbags, however, this is not the case. Airbags help avoid injuries, but only seat belts can save lives. But if no one in their right mind would turn off the airbags, then it is not always possible to force them to use the belts correctly.
To automate the tension, winding (reel) and locking (inertial) mechanisms were introduced into the design. Additionally, emergency tension devices with squibs are installed.
What does a jammed belt mean?
If the seat belt does not pull out of the installation socket, it is most likely jammed. To understand what this means, you first need to understand how it works. When the belt does not extend, 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 the principle of operation.
Vehicle seat belt
Inside the blocking device there is a sensitive element responsible directly for blocking, which is made in the form of a ball. This ball, moving through a system of levers, clings to the body of the coil gear. If the belt is retracted too quickly, the spool disc puts more force on the screw surface, thus blocking the ball.
If the lock is jammed and cannot be turned off, this means that over time the security mechanism has begun to function incorrectly.
In such cases, the strap does not retract and cannot be turned off in any way. In such cases, even an attempt to slowly latch the element may not help - it simply jams and no longer retracts, does not work.
Operating rules
The procedure for proper operation of the protective accessory in question is regulated by the following rules:
- The shoulder part of the tape must go over the chest and shoulder; it is forbidden to thread it through other parts of the body, even if it causes inconvenience.
- When the seat back is positioned vertically, maximum protection is achieved when using a seat belt. Leaning the seat back increases the risk of a person slipping under the belt. Under these circumstances, a head-on collision will result in the passenger striking the instrument panel.
- One seat belt is designed for one passenger; two people are not allowed to wear it together.
- It is forbidden to drive with a child in your arms with a seat belt fastened. In this case, the accessory not only does not protect the adult passenger, but can also cause injury to the child in the event of an accident. The child must have a separate seat belt or child seat.
- It is prohibited to add or change the design of the device in question in order to weaken the tension or block the tightening of the belt.
- Make sure that the tape fits against your body and does not twist.
- If the child's height allows him to be fastened correctly, the use of a belt is mandatory. If the child is too small, a child car seat should be used.
- The waist part of the tape should be adjacent to the area above the hips.
- Adjust the mechanism to ensure a snug fit of the tape to your body.
A seat belt malfunction may be caused by the following reasons:
- blocking as a result of an accident occurs due to the activation of the mechanism’s squibs;
- the seat belt buckle is damaged due to a breakdown of its main mechanism;
- the roller mechanism is subject to wear;
- influence of negative temperatures;
- wear of the locking system or one of its elements.
Repair process
Now that we have dealt with the signals and reasons for blocking a fastened and unfastened seat belt, let’s move on to the repair process. Cleaning seat belts is one of the main tasks in this process, so we will consider this procedure separately. So, what should you do if you receive a signal that the lock is jammed? How can I clean it or turn it off? You will learn more about this below.
Tools
To disable the lock if a 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:

The leaders of the Chinese automobile company Geely showed the appearance of the updated cross-hatchback GS.
According to official data, sales of the new product in Russia will begin in the fall of 2021. It was not by chance that photographs of the new hatchback were posted on the manufacturers’ website. It is with this car that the leaders of the Chinese company plan to begin expanding the range on the Russian transport market.
In June 2021, the updated car passed the necessary certification procedure. According to the documents received, under the hood of the car there is a 1.8-liter engine with a power of 133 horsepower. Both manual and automatic transmissions operate in tandem with the selected unit.
For the production of vehicles, the modernized platform of the Emgrand family was chosen, which was presented by the designers in 2016. The exact cost of the cars has not yet been announced. According to company executives, the exact cost and all detailed data about the new product will be announced together with the start of implementation.
The designers of one of the popular automobile companies announced that the updated Fiat 500 model may receive a hybrid version.
According to preliminary data, hybrid cars may appear in the brand’s lineup in the near future. The company's designers announced the electrification of the 500 model back in 2021. According to the data provided, the hybrid installation will include a 1.3-liter turbocharged engine with a power of 177 horsepower.
As part of FCA's plans, the company must release at least 30 electrified models until 2022 inclusive. There is no exact information about when the brand’s electric vehicles will appear on the global transport market.
But despite this, manufacturers understand that the production of hybrid car models allows Fiat to enter the market of environmentally friendly cars with low levels of harmful emissions.
Of course, it takes time for the brand’s hybrid models to appear on the transport market. But despite this, the company’s designers are ready to actively develop in this direction, creating modern electric car models.
Experts have compiled the TOP 5 new cars that went on sale over the past 6 months of this year. Among the leaders were world-famous brand concepts, some of which are not yet available for purchase in Russia. The information was published by the portal “Speedme.ru”.
According to analysts, the hybrid Lexus ES 300h deservedly takes first place. The sedan will be an excellent alternative to German cars in this segment. On the Russian market, the car is sold as standard; a hybrid car is not yet available to fans of the brand.
The starting price for the Lexus ES 300h in Russia is 2 million 690 thousand rubles, and the car is available in three versions: ES 200, ES 250 and ES 350.
The BMW X5 xDrive40i crossover is on the second line of the list; it received a 3-liter engine and a power of 340 hp. The model will accelerate to 100 km/h in 5.5 seconds, the starting price in Russia is 4 million 930 thousand rubles.
The Audi Q8 coupe-crossover rounded out the top three, and the starting price in Russia will be 5 million 60 thousand rubles. The diesel unit under the hood of the car produces a power of 249 hp, and its volume reaches 3 liters. It is paired with an 8-speed automatic transmission and all-wheel drive.
The Jaguar I-Pace crossover, equipped with an all-electric drive, dropped to fourth place. It is equipped with a 394-horsepower engine, and the price of the model starts at 6 million 250 thousand rubles.
The top five is closed by the new Genesis G70, with performance ranging from 197 to 247 horsepower, depending on the version. You can buy a car in Russia for 2 million 190 thousand rubles in standard configuration.
Diagnostic methods
Let's look at the procedure and methods for checking the condition of seat belts. For example, let's look at how to carry out diagnostics on a Ford Focus car.
Insufficient belt retraction
If the belt does not retract well, check how the decorative covers are installed to make sure they are not touching the belt tape. Also check to see if the belt is rubbing against the retractor. If this is the case, then loosen the fastening bolt and align the device so that the tape is in the middle.
Most cars have 2 front and 3 rear retractable seat belts. They are equipped with double protection by sensitive elements.
- Vehicle motion sensor – blocks the belt during braking, sharp turns, descents, and ascents.
- Belt movement sensor – blocks it when pulled sharply.
These systems must function properly. To check them, special control methods are used.
How to check a car motion sensor
There are two ways to test this sensor.
Causes of the problem
There are several main reasons why a seat belt does not extend. First of all, it should be noted the banal wear and tear of the system. Moreover, this may only apply to 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 conditions also provoke such malfunctions. may cause this phenomenon.
Sometimes seat belt pretensioners fail after an accident. This may cause the coil lock or the entire main mechanism to break. After an accident, in many vehicles the belt may not retract back into its intended location at all. This is due to the activation of the system's squibs.
If the car is involved in an accident, even with smooth pulling, the mechanism may jam. Then you will have to look for the cause of the breakdown and eliminate it.

| Look under the back seat. If there are any on the racks, then they should be there even more so. |

| On the right in the photo, the end of the belt runs along the arch of the wing, does that mean it is attached somewhere on the arch? |

| the inertial block is simply screwed to the shelf, and where is the safety, it will vomit in the event of a serious impact, another small question is where the other end of the belt is screwed, sorry for the trouble. |
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)

How to repair
After finding out the reasons for the malfunction of the seat belt reel, we will figure out how to repair it and what is needed for this. In this procedure, the main thing is to thoroughly clean the belts.
Required Tools
To resolve a malfunction of the seat belt buckle, the device will need to be cleaned. This will require certain tools and accessories.
- Short shaped screwdriver.
- A 17 mm wrench is better than a socket type.
- Flathead screwdriver.
- Clothes pin for office work.
- A syringe with a thin tube.
- Gasoline for lighters.
- A piece of polyethylene to protect the seats from dirt.
- A piece of steel wire.
Effect of frost
Sometimes the seat belt latch may not work due to extreme cold. This will not require changing any parts. In some older vehicles, the insulation of the mechanism 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, could be silicone grease or lithol.
In some cases, the situation can be corrected by bending the metal “claw” of the ball mechanism at a smaller angle. When the coil is positioned vertically, the retainer should not come into contact with the gear teeth. This should only happen when the bobbin is tilted.
