Removing the front seats of a VAZ 2107

To dismantle the seats you will need a pair of keys - 8 and 13 mm. The procedure is as follows:

• Move the seat forward as far as it will go.
• Unscrew a couple of bolts securing the slide.

• Move the seat back.
• Remove the two bolts securing the front seat.
• Repeat the steps for the second chair.
• Remove the VAZ 2107 seats from the interior.

Repair of front seat slides

VAZ front seat slides include the following parts:

Repair of seat mechanisms is carried out with the seats already removed. To restore the functionality of the mechanism, the following operations should be performed:

• clean from dirt;
• if necessary, replace worn or damaged parts;
• lubricate

Dismantling the slide is done as follows:

1. Remove the spring.
2. Remove the rod pin.
3. Unscrew the bolts securing the slide to the seat.
4. Remove the skids.
5. Remove the screw rod from the bracket.
6. Move the sliders along the guides.
7. Remove sliders and rollers.

After disassembly, you can inspect the parts to determine the cause of the breakdown. The lack of fixation of the seat back of the VAZ 2107 can be eliminated by replacing it (or replacing the comb or clamp). To do this, you will have to cut off the broken part with a grinder and weld a new one in its place. The upholstery of the chair must be protected from welding by covering it with a wet cloth. If possible, it is better to leave one frame of the chair before welding. At the same time, you can wash the seat upholstery.

Reupholstery of the front seats of VAZ 2107

To reupholster the seats you need:

• 
  Rip out the old sheathing at the seams.

• Moisten the places where the covering is glued to the cardboard elements with gasoline.
• Carefully remove the casing.
• Using the removed error as a template, mark and cut the workpiece from a suitable dense fabric.
• Renew foam elements and springs.
• Assemble the pieces of sheathing and secure them using heat welding, glue and thread.

Replacing seats

You can make the interior more comfortable by installing seats from another car model or special seats for auto tuning on the VAZ 2107. The latter are produced in various modifications, which allows you to choose a seat that suits the car owner.

You can install any car seats from foreign cars that are suitable in size in the VAZ interior. It should be noted that such a replacement requires welding to change the fastening design. During welding, it is necessary to protect the casing from sparks. If you don’t have a welding machine at your disposal, you will either have to be content with the available selection of car seats, or contact a specialist.

How to remove the front seats

The question of how to remove the front seats on a VAZ 2106 arises quite rarely, and in most cases this happens due to their breakdown. The most common of them is when the backrest is not fixed in a vertical position. There are also cases with the slides when the chairs begin to move on them with difficulty. In general, in this case it is better to remove the seat and figure out what is causing the damage. For this procedure you will need:

1. Head 8 with extension
2. Ratchet handle or crank
3. Open-end wrench 13

The chairs are secured with 4 bolts, two of which are in the front, and the other two are in the back! First, move the seat all the way forward, thereby gaining access to the rear mounting bolts:

How to remove seats on a VAZ 2107 (2106)

Repair and tuning of the Six's interior includes the dismantling of car seats. Before removing the seats on a VAZ 2106, you will need to buy a socket set to “8” and an open-end wrench to “13”. When carrying out installation work, the lack of connection between the front seats is taken into account. They are mounted on a skid fixed to the body using 4 brackets.

Step-by-step instruction

First, the front seats are moved all the way forward (to provide access to the rear brackets). Then the chairs are moved back. To unscrew the bolts you will need a “13” wrench. Disconnect the electrical connector from the front seat. The next stage is dismantling the seats.

The brackets are tightened to a torque of 20 N.m. The seats are moved forward, the rear brackets are tightened using the same method. The wires are connected to the battery. If the slides are installed, they are lubricated with Fiol-1 or Litol-24.

To tune the interior of the VAZ 2106, you will also need to remove the rear seat. First, experts advise studying the design of the rear seat. This sofa consists of a cushion and a backrest. The first element is fixed with two spikes welded to the body of the “six”. These spikes are installed in special holes located along the edges of the sofa.

To remove the seat, you will need to insert a screwdriver between the floor of the “six” and the edge of the part being removed. By pressing the screwdriver, they undermine the sofa from its seats. The next stage is dismantling the backrest. This element is fixed with two brackets welded to the vehicle body. If the seat cushion is removed, the backrest is removed by lifting it upward. Such movements must be sharp. First we pull one side, and then the other. Installation of the sofa is carried out in the reverse order.

Repair work

Standard six car seats can break during operation. More often the chair adjustment does not function, misalignment or bedsores have appeared. To repair the seat, you will need to remove special latches along the edges. To remove the plate, use a flat-head screwdriver.

After dismantling the slide mechanism, it is recommended to inspect the chair frame. If the seat is damaged, repair work is carried out using a grinder, welding and a hammer. Then the frame is painted. The structure is assembled in reverse order.

To repair the back, you will need to remove the standard cover.

To do this, bend the teeth using a screwdriver. The next stage is dismantling the canvas and decorative inserts. After removing the entire cape, the back is dismantled. The frame is inspected for defects.

If a crack appears in the back, repair work is carried out using a hammer and plywood. A crack may also appear in the fastening of the rotating mechanisms. In this case, it will need to be cut out with a grinder. We repair the mechanism by welding and hammering. The next stage is assembling the rotating mechanism and synchronizing it. You will first need to clean and lubricate the connecting rod.

If the mechanism in the repaired unit works well, the structure is assembled. Then the functionality of the node is re-checked. The component elements of the mechanism must work synchronously and in parallel. The structure is clamped with a clamp, welded, protected and painted.

If the headrest of the VAZ 2106 seat is loose, insert copper strips into the clamps. It is recommended to clean and lubricate rusty fasteners. The headrest pillars have straight bottom slots. To quickly dismantle the head restraints, it is recommended to install lower grooves. The back and headrest are assembled in the reverse order. Repair work on the “six” seats has been completed.

Disassembling the seat of a VAZ 2107

All owners of the domestic VAZ 2107 car know how uncomfortable and peculiar the front seats are. In addition to everything, during the operation of the car, this often happens when the back of the VAZ 2107 seat breaks. It suddenly stops being held in an upright position. How to fix the breakdown, and what is better to choose - repair or installation of new chairs, we will find out in the process.

Novikov Maxim Glebovich – Repair of the seat back tilt regulator VAZ-2107.

This is probably completely funny, but today I am publishing another article about repairing broken parts of VAZ cars, which, as usual, cost pennies anyway. I was prompted to write this article by another breakdown of my car, namely the passenger seat backrest tilt adjuster. I don’t know who I drove so heavy (and I never bombed), but on the passenger seat the adjuster comb was completely cut off, and the backrest did not lock in any position at all, tipping over into the back seat when I tried to lean on it. Naturally, I was too lazy to go to the service center, and I decided to see for myself what was broken there, and whether it was possible to fix it myself.

In general, this breakdown happens on Zhiguli cars quite often. Usually, for repairs, the chair is removed, the welded comb is cut off, and a new one is welded. But at home, it would be possible to do without welding, simply by drilling out the spot welds, cutting off the weld with a chisel, and screwing the new comb into place through the drilled holes. But I didn’t have time to look for a comb, and I had already taken the drill from the dacha to Moscow (and I started doing repairs at the dacha). Therefore, I decided to simply fix the backrest in one position, since none of the potential passengers are particularly trying to adjust it.

So, the method for quickly fixing the tilt of the seat back of a VAZ-2107 car in case of a comb failure:

1. Remove the chair. To do this, move the chair all the way back, unscrew the two front bolts on its lower runners, then move the chair all the way forward and unscrew the two rear bolts on the same runners. We pull the chair out and turn it over, as if putting it on all fours. We study the lower part, in particular the latch itself.

The picture shows a chair back tilt lock with broken comb teeth. Thanks to the teeth, part 1 should be fixed in part 2, but since the teeth of part 2 are broken, fixation does not occur.

However, as you know, all the parts in Lada cars have clever design features, which seem to be specially laid out so that we can repair or modify these parts. Let's pay attention to the grooves of part 2, marked with arrows in the figure. They are approximately the same width as the distances between the ribs in part 1 (actually a little wider). This allows us to easily fix these two parts by inserting the part shown in the next photo.

2. We make a retainer. It is easy to make from a fairly common metal strip, a fragment of which can always be found by rummaging thoroughly in your or your neighbors’ barn. I found such a strip, and its width turned out to be exactly equal to the distance between the extreme points of the grooves, and the thickness was exactly equal to the width of the grooves, which is important for eliminating backlash. All that remains is to cut out a notch in the center and use sandpaper to slightly narrow the thickness of the plate within the boundaries indicated by the red lines, since, as mentioned above, the distance between the edges of part 2 is slightly less than the width of the grooves themselves, and therefore the thickness of the part.

3. Now let’s adjust the desired level of inclination and hammer the lock into place, paying attention to its orientation (narrow tooth in a shallow groove, wide tooth in a deep one):

Removing front seats instructions

The need to dismantle the front seats arises in the following cases:

• A breakdown that can only be repaired after dismantling.
• The need for soundproofing of the interior, in particular the floor.
• Replacing standard seats with others.

One of the common problems with seats on the VAZ 2107 is a broken or malfunctioning backrest. The design of the front seats provides the ability to change the angle of the back support, but when the mechanism breaks, this function stops working. The driver or passenger does not have the opportunity to lean on the backrest, because it tilts (the seat folds out) even with minimal back pressure, and driving a car in this position of the backrest is inconvenient. To find the cause of the breakdown and eliminate it, you will first need to dismantle the faulty seat and remove it from the car.

Instructions on how to remove the front seat on a VAZ 2107 are as follows:

1. First, the seat moves all the way forward. For this purpose, the mechanism has a corresponding lever in its design. After moving it forward, the inside of the slide will open from the rear of the cabin, fixed to special bases on the floor of the car using two bolted connections.
2. These bolts must be unscrewed and removed using a socket head or an “8” spanner.
3. After this, you need to pull the chair movement lever again and move it as far back as possible.
4. There are also two bolts on the front of the slide that must be unscrewed to dismantle the chair. At the same time, keep in mind that one bolt securing the slide at the front goes under the head at “8”, and the second at “13”.
5. Now you can remove the chair from the interior by turning it towards you.

The procedure for dismantling the second chair is carried out in a similar way, if it needs to be repaired or replaced. After removal, you can begin to diagnose faults. We will find out in detail what types of backrest breakdowns occur and how they can be eliminated.

Repair of the front seat of the seven

Owners of 7s know that backrest malfunction on this car is a fairly common problem, and if you still have the factory seats in the front, you probably had to repair them more than once. The mechanism for adjusting the back support for the front seats is very weak, and therefore at one moment a situation may occur when it does not lock, but begins to dangle. Sitting in a chair with a faulty support is like driving a car while sitting on a stool. It’s not very pleasant, and therefore if the side backrest of the front seat of a VAZ 2107 is broken, then you definitely need to get it repaired. Repairing the backrest is easy to do with your own hands, and we’ll find out in detail how to do it.

The reason for the failure of the backrest fastening is the adjustment bracket, due to which the device not only moves, changing position, but is also fixed. It is this bracket that is the weak point of the front seats on the sevens, and how to restore it is described step by step below:

1. After removing the seat, it must be turned over. We are not interested in the backrest, but in the pillow, in the lower part of which there is a mechanism for adjusting the position of the stop. It looks like this, as shown in the photo below.

2. It is clear from the design that the mechanism is very weak, which is why it often malfunctions. To restore and restore the fastening, you will need to buy a special part. It is specially designed for repairing classic seat backs, and is called a comb.

What seats can be installed in a VAZ 2107 car?

Initially, the car was equipped with inexpensive seats, since the car belongs to the “economy” class. However, the seats of the “seven” have a number of advantages compared to earlier car models.

They added:

• lateral support;
• headrests in a single body with the backrest;
• folding armrest in the rear seats.

In some cases, due to personal preference or necessity, drivers replace the basic seats.

Seats from foreign cars

Often, VAZ drivers choose seats from foreign cars for their cars.

The following options are suitable for the 2107 and will not require major modifications:

• Mercedes W210;
• Toyota Corolla.

A Volkswagen seat will do. However, in this case, the seating position is too high and is only suitable for short drivers.

If you want to install a seat from a Peugeot or Nissan car, you will have to spend time on installation, since the fastenings are different. For reliable fastening it is necessary to make additional holes.

Drivers often use seats from SKODA or Fiat cars.

Racing seat

Expensive option. Sometimes the cost of the seats is equal to the price of the car itself.

The main feature is the one-piece design of the back and pillow. The model uses fiberglass. These seats are chosen by racing drivers. Since the chair can be adjusted exactly to your figure. To do this, modeling inserts are installed in the seat.

Despite the robust design and comfortable ride, getting into and out of a car with racing seats becomes more difficult. The seat, made of fiberglass, makes driving absolutely uncomfortable on our roads. Such seats should only be installed when participating in racing; they are not suitable for other purposes.

Sports option

Unlike the racing version, the sports seats have adjustable backrests and shoulder rests. Added hip and back support feature. This is the most comfortable seat option.

This type of seat is equipped with a special belt to increase safety. Sports seats are recommended to be installed exclusively in cars with rigid suspension. If the suspension is soft, long-distance driving will not be comfortable.

Anatomical chair

For those who prefer a quiet ride, an anatomical chair will be the best solution. This type of seat stabilizes the body when turning, providing a comfortable fit.

Changing the adjustments will allow you to customize the position of the chair to suit you. Some models have added heating and vibration massage functions.

An anatomical seat is suitable for those who drive often and for a long time. This will be a solution for those who experience back and neck pain during long journeys.

Auto mechanics assure that this model can be equipped with a seat of almost any type and from any other car. The main thing is that the dimensions are respected and welding can be carried out.

Repair of front seats of VAZ-2104, 2105, 2107 (the backrest falls)

The essence of the problem and solutions

The back of the front seat of the VAZ classic falls back due to wear and cutting of the teeth of the latch comb. This is the part that will have to be replaced during repairs. You can buy it at an auto parts store; there are right and left combs (do not mix them up). At the same time, you can replace the locking screw.

These brackets need to be replaced

The price is not very high, but the repair itself is complicated: you will need to cut out the old part (it is welded by contact welding) and weld a new one. Therefore, you can take on repairs only if you have a garage equipped with welding, an angle grinder, a drill and other plumbing tools and you know how to use them all.

Another way to restore the retainer is to use a repair (reinforced) comb. It is welded directly onto the broken fastener; there is no need to cut anything off and the repair is faster.

Repair (reinforced) seat back clamp for VAZ-2107

If you don’t have all this, then try looking at auto repair shops for a seat with a well-preserved latch. Even if its cover or cushions are damaged, you can transfer the upholstery from your seat to a new frame. Welding is no longer needed here; anyone can do the job.

Removing the seat

You will need “8” and “13” mm wrenches, preferably socket wrenches with a ratchet. Move the seat to the extreme forward position.

We unscrew the two screws of the rear fastenings and remove them from their sockets.

Unscrew the seat mounting screws

Move the seat to the rearmost position. We unscrew the screw at “8” of the outer fastening at the top and the nut at “13” at the bottom of the seat near the inner fastening. We take the seat out of the car. We turn the seat over and place it on a stand for ease of use. You can simply put it back in the trunk.

Installing a reinforced seat clamp comb

To install a reinforced comb, you need to straighten a worn and broken comb. Protect the seat cushion and the screw with linings made of fireproof materials. Boil cracked parts. Install the reinforced comb, aligning it with the screw and welding it to the bracket.

Disassembling the pillow

If you decide to install a new factory-made bracket, you will have to remove them to avoid burning the foam and other parts of the seat cushion when cutting and welding the bracket.

To do this, remove the covers, if any, and use a flat screwdriver and pliers to bend the metal tabs around the perimeter of the seat.

Bend the trim tabs

Carefully unhook the trim and remove the pillow.

Removing the worn-out bracket

We take out the wire retainer of the screw and turn the screw out of the socket. To avoid interference, it is better to remove the seat slide from the side of the bracket by unscrewing the two fastening screws.

Remove the stopper and turn out the screw

To remove the old part, you need to drill out the welding points with a drill of about 5 mm. Where this is inconvenient, you will have to use a grinder and a chisel.

We adjust and weld new parts

Set the backrest to the “sitting” position and mark the position of the new part.

We grab the comb at two points and check once again for correct installation.

We finally boil the part.

After cooling, we clean the seams with a grinder and cover them with paint or anti-corrosion mastic.

We weld the backrest clamp bracket

We check the condition of the springs, solve the problem of “sagging”

While the seat cushion is disassembled, another problem can be solved. The springs often break off from the sides of the seat and it begins to sag greatly under your weight. Weld metal plates of suitable replacement in place of the broken ones and fasten the springs in place. You also need to return the wires that connect the springs to each other. If they are lost, then look for a suitable replacement.

How to fit and weld new parts

To carry out the work, follow the steps:

• bring the backrest into a sitting position and mark the position of the part;
• grab the comb in two places;
• weld the part;
• after the welding has cooled, clean the seams using a grinder;
• cover the part with paint and anti-corrosion mastic.

Installing a reinforced seat clamp comb

In order to install a reinforced comb, you will need to straighten the old one. Protect the cushions and screw with non-burning pads. Boil the damaged part. Afterwards you can install the comb, aligning it with the screw. Then weld it to the bracket.

Removing the front seats of a VAZ 2107

To dismantle the seats you will need a pair of keys - 8 and 13 mm. The procedure is as follows:

• Move the seat forward as far as it will go.
• Unscrew a couple of bolts securing the slide.
• Move the seat back.
• Remove the two bolts securing the front seat.
• Repeat the steps for the second chair.
• Remove the VAZ 2107 seats from the interior.

Repair of front seat slides

VAZ front seat slides include the following parts:

Repair of seat mechanisms is carried out with the seats already removed. To restore the functionality of the mechanism, the following operations should be performed:

• clean from dirt;
• if necessary, replace worn or damaged parts;
• lubricate

Dismantling the slide is done as follows:

1. Remove the spring.
2. Remove the rod pin.
3. Unscrew the bolts securing the slide to the seat.
4. Remove the skids.
5. Remove the screw rod from the bracket.
6. Move the sliders along the guides.
7. Remove sliders and rollers.

After disassembly, you can inspect the parts to determine the cause of the breakdown. The lack of fixation of the seat back of the VAZ 2107 can be eliminated by replacing it (or replacing the comb or clamp). To do this, you will have to cut off the broken part with a grinder and weld a new one in its place. The upholstery of the chair must be protected from welding by covering it with a wet cloth. If possible, it is better to leave one frame of the chair before welding. At the same time, you can wash the seat upholstery.

Rear seat repair

The backrest of the rear seat can be easily removed. To do this, you need to lift it slightly so that the staples are separated from the latches. To remove the saddle, you should grab it by one edge with both hands and pull it up strongly, this will ensure it moves away from the lock. Then the same is done with the other side, after which the repair can begin.

Fastening the front seats

Many owners of the VAZ 2107 model, which has already been discontinued, want to decorate the interior by installing seats from other car brands. This primarily applies to the front seats.

In this case, you should pay attention to UNP products. Which seats are suitable for VAZ from the company’s catalog? Almost everything

You can choose anatomical seats, such as “Boxer”, “Racer”, “Sport”, etc. They are quite lightweight, since the frame is made of durable fiberglass, have a steel frame and a bucket shape with lateral supports, which increases the quality of driving. The seat backs often have reinforcing pads, and the headrest is integrated. The seats are thin due to fiberglass, which gives additional space to passengers sitting in the back.

Sports UNP seats are perfect for the VAZ 2107. They have maximum lateral support, a one-piece design, an integrated headrest, allow you to install sports belts (3-6 attachment points), additional pillows, including lumbar support. All UNP products can be easily integrated into any car due to the availability of installation adapters, which are sold along with the seats. In the case of the VAZ 2107, we are talking about the slide and side mounting brackets.

Installing a sports or anatomical car seat is not a cheap pleasure, so many car enthusiasts want to know whether seats from a foreign car will fit in a VAZ 2107. Experts believe that almost anything that fits the dimensions can be supplied if it is possible to carry out high-quality welding work. For example, in the “seven” you can try to put parts from Opel (Vectra A, Cadet) or from Skyline.

Reupholstery of the front seats of VAZ 2107

To reupholster the seats you need:

• Rip out the old sheathing at the seams.
• Moisten the places where the covering is glued to the cardboard elements with gasoline.
• Carefully remove the casing.
• Using the removed error as a template, mark and cut the workpiece from a suitable dense fabric.
• Renew foam elements and springs.
• Assemble the pieces of sheathing and secure them using heat welding, glue and thread.
