Keeping seat belts clean affects more than just the appearance of the interior. Over time, the internal mechanism becomes clogged and begins to jam, causing problems with fastening. Car enthusiasts are often interested in how to remove seat belts in order to completely remove dust and dirt. It is better to learn in advance about the removal methods, because if you make a mistake, you can damage the winding reel and other parts of the mechanism.

Design and types of seat belts
These devices differ in the number of attachment points. There are modifications from two-point to six-point. Two-point ones are found in older cars; they are attached to the waist on both sides of the seat. Modern cars use three-point belts that evenly distribute the energy of a moving body. Other types are installed on sports cars. Five-point ones are also attached to child car seats.
The design of a modern three-point belt consists of the following elements:
- The strap is made of durable material - it is attached not to the seat, as in sports cars, but to the body. A metal tip is attached to the end; the person locks it before the trip. It has three attachment points - on the threshold, rack and rod. Most models provide the ability to adjust the belt depending on the height of the passenger.
- Retractor reel - allows you to unwind the belt. It is designed in such a way that it is blocked during a sharp jerk. Therefore, in the event of an accident, the belt does not unwind.
- Lock - necessary to secure the belt. It usually sends a signal to the dashboard to remind the driver to buckle up.
- Tensioner is a device that includes shock sensors. When there is a strong impact, they send a signal to the control unit, which activates the tensioners. To ensure that when the freedom of fit decreases, the belt does not exert excessive pressure on the person, a limiter is installed.
Seat belt
If one of the mechanism components malfunctions, it is necessary to repair the damage as soon as possible. But repairs can only be made after removing the seat belt. Motorists often have to disassemble this element. This is due to the fact that, like other parts of the interior, it becomes dirty over time. To wash a belt, you must first remove it, and do it correctly.
Seat belt repair
Available repair methods include partial disassembly of the mechanisms, cleaning, washing, drying and lubrication.
Tools
Not in all cases, repairs can be made using standard tools. Sometimes the internal fasteners contain non-standard screw heads, making it difficult to purchase the corresponding keys.
But in most cases you will need:
- a set of keys for removing housings from the body;
- slotted and Phillips screwdrivers, possibly with replaceable Torx-type bits;
- a clip for fixing an extended belt;
- a can of aerosol cleaner;
- universal grease, preferably silicone-based.
The procedure depends greatly on the specific car model and belt manufacturer, but there are some general points.
Instructions
- The belts are removed from the body. To do this, you will need to unscrew several bolts from the body nuts using socket or socket wrenches.
- Use a thin screwdriver to press out the fasteners, unscrew the screws and remove the plastic covers. Unless necessary, do not touch the cover under which the spiral spring is located.
- The ball body is removed, the parts are cleaned and inspected, and if spare parts are available, worn or broken ones are replaced.
- The mechanism is washed with a cleaner, dirt and old grease are removed. A small amount of fresh lubricant is placed in the friction zones. You can’t have too much; too much will interfere with the free movement of parts.
- If you need to disassemble the inertia mechanism and spring, remove the cover after removing the fasteners with extreme caution. The levers of the mechanism must move freely and jamming is not allowed. To increase the tension of the spring, its inner tip is removed, the spiral is twisted and fixed in the new position.
- The parts should be washed with cleaner and lightly lubricated.
The best solution would be not to try to repair the belt, especially if it has been in use for a long time, but to replace the entire assembly with a new one.
Over time, the reliability of operation decreases, and the likelihood of successful repair is also low. Finding new parts is almost impossible, and used ones are no better than existing ones. Saving on safety is always inappropriate, especially when it comes to belts.
Their material itself ages quickly and in case of danger, all this will work abnormally, which will lead to injuries. No airbags will help if the belts fail; on the contrary, they can become an additional danger.
How to remove rear seat belts
The instructions below show removal on a domestic car. First you need to use a screwdriver to pry off the plug on the bottom bolt that holds the belt in place. This bolt is located near the door, next to the threshold.
The coil is mounted at the rear, on the trunk side. The other two points are attached to the interior. First, unscrew the coil.
Remove the plug from above the chair and unscrew the bolt. This is the top attachment point.
Unscrew the bottom bolt located near the door. After this, you can remove the element that will be cleaned.
How to remove front seat belts
First, unscrew the two bolts located at the bottom of the plastic box.
Then use a flat screwdriver to pry up and remove the plug. Underneath there is a bolt that needs to be unscrewed.
There is one more bolt left on top of the plastic box, which also needs to be unscrewed. Next, unscrew the top fastening.
Now you need to open the plastic window on the box and pull out the textile element along with the coil.
To remove belts on a foreign car, for example a BMW, you first need to remove the plastic covers. They are attached using four clips, two of which are attached at the bottom. The other two are fixed on top.
The fastening elements are unscrewed using a TORX key.
Then you need to unscrew the bolts of the fixing metal part. In this case, only one bolt can be unscrewed.
The plastic cover is removed using a special tool. You can also pry out the plastic with a regular screwdriver. There will be quite a lot of dust inside.
Now all that remains is to unscrew the bottom bolt.
After unscrewing the bolt, the belt should come out easily.
To wash the belt, the removed mechanism must be disassembled. Next, installation is performed in reverse order.

We will tell you step by step how to remove the belt on VAZ models.
First you need to use a screwdriver to pry and remove the decorative trims of the lower and upper seat belt fastenings.
There will be bolts under the covers that need to be unscrewed with a 17mm wrench.
Next, remove the upper belt fastening bracket.
Next, you will need to remove the plastic cover to free the coil. To do this, you need to unscrew several screws on it:
- two on the lower pillar, near the sills;
- one - in the central part of the pillar, near the seat belt guide;
- and another one at the top of the counter.
The cover is removed.
Next, you need to remove the coil - it is located at the bottom of the rack. To do this, use a 17mm wrench to unscrew the bolt holding it in place. Afterwards the coil is simply removed.
All is ready!
How to pull a seat belt out of a reel
When all the bolts are unscrewed, you need to correctly pull the belt. To do this, you need to pull it while holding the coil with your finger. To pull out the end with the stopper, you need to pull harder.
Now you need to carefully pull the strap out of the reel, holding it.
Pulling the seat belt from the reel
In this case, you need to make sure that the spring does not unwind. To do this, place a screwdriver inside the mechanism instead of a stopper. This is very important, since an unwound spring is difficult to put back into place manually.

How to remove a jammed belt
If during disassembly you cannot pull out the strap, then the reason is that the mechanism is jammed. In this case, it is impossible to pull it out; the belt gets stuck and does not move. To solve the problem, it is enough to use the tools that most car enthusiasts have in their garage.
First, you will need to unscrew the screws on the lower trim of the middle door pillar (if there are no screws on the trim, it may simply be held on by brackets/clips). After this you need to remove the cover. To do this, just lift it and pull it towards you. Next, you need to pull out the belt and lock the mechanism.
Removing the center pillar trim
The next step is to unscrew the bolt that holds the coil in place. Once unscrewed, it can be easily removed.
To prevent accidental winding, the strap is secured with a paper clip. The coil needs to be shaken, the mechanism should shake. It is important to remember where it is. Using a thin wire, it is important to squeeze out the plastic caps. When removing, the pistons must be held, as they may fall and get lost.
Now you can use a slotted screwdriver to pry and remove the cover located on the mechanism side. Under the lid there should be a plastic box with a cylinder, in the middle of which there is a metal ball. The rocker arm of the locking mechanism will also be attached here. The box needs to be hooked with wire and pulled out.
Disassembled seat belt reel
Next comes the check. It is important to check the rocker arm, which should rotate freely on the axle. If this unit jams, then the axle needs to be washed and the clogged dust removed.
After checking the primary mechanism, you need to inspect the main one. It is also under the cover. This unit, made of metal, is located under the plastic gear. You can remove the gear from its recess without using tools. In the middle of the connector there should be a toothed ex class=”aligncenter” width=”640″ height=”480″[/img]
Then remove the paper clip from the belt, while holding it to prevent it from unwinding. The connector of the main mechanism must be cleaned of contaminants, which often cause jamming. To do this, first carefully pour gasoline over it. You need to take the reel while holding the guide. At this time, wind the belt with your right hand, while trying to tighten it.
It is necessary to make several sharp jerks for the mechanism to lock. After the manipulations have been completed, the belt is again installed on the reel. And again you need to wind it several times, while simultaneously tightening it. The performed operations should solve the jamming problem.
More details and more clearly about this process in the video:
Possible problems when removing the belt and after it
It happens that the driver pulls out the belt, but it does not tighten at all. Most likely, the reason is not at all due to incorrect installation of the node. Most often, this problem is caused by a breakage of the spring inside the drum. It is a consumable item and can be easily replaced.
The opposite situation also occurs when the strap jams and does not extend. This means that the internal mechanism lock has broken. Such cases often occur after an accident. Then you need to follow the instructions above, which indicate what to do if it jams.
If the spring unwinds during removal, it will be difficult to wind it back. But it is not necessary to immediately change it to a new one. The coiled spring must be wound in the direction in which its short part is directed.

Can seat belts be restored after an accident?
Main components of belts
The need to repair and restore seat belts after locking is relevant for almost all motorists who have ever been involved in an accident. The belt mechanism reacts to certain situations as if it were a traffic accident. This is either an accident and airbag deployment, or simply a high load on the device. At such moments, the squib 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 choice but to cut off the belt and install a new one instead. But in most vehicles, the products can be restored; their mechanisms can be repaired. Often in cars, during a collision, the systems fire both squibs in the front seats. Therefore, if you are eating alone and there is no passenger nearby, you should still check whether the strap works.
Other causes of belt failure
Strap blocking can occur for other reasons:
- Natural wear and tear of products. As a result of prolonged use, the strap stops retracting. This is due to wear of both the belt itself and the locking mechanism or one of its elements.
- The strap does not retract due to low negative temperatures or wear of the roller device.
- The coil lock has broken down or the main device has failed.
- The strap does not retract after it is detached, or it is jammed as a result of trying to fasten it.
