Each front seat is mounted on two skids and an oscillating post 19 (pic. 167), which are attached to the body brackets and to the floor. The rack has two torsion bars 22, making it easier to move the seat forward. The working stroke of moving the seat forward and backward is 119 mm.
The base 1 of the seat cushion is stamped from 0.9 mm thick sheet steel. The base 10 of the backrest is made of strong steel frames to which wire springs are attached. To avoid creaking, the ends of the springs are covered with a layer of polyamide resin. The bases of the backrest and pillows are hinged to each other. The bases of the backrest and cushions are padded with soft polyurethane foam padding and covered with upholstery. In the guides 6, a headrest 5 is installed, which is adjustable in height.
Guides 12 (pic. 168) and sliders 2 and 10 of the sled are stamped from sheet steel. The movement of each slider along the guide is carried out along two rollers 11. The seat is fixed in the desired position by latches 5. each of which is pressed by a spring 4 into one of the grooves of the comb latch 1 of the movement mechanism. The clamps are welded to the guides. The levers 6 of the latches of the inner and outer sled are interconnected by a rod 8. The rod 13 of the latch of the outer sled has a handle for the movement mechanism.

Front seat sled: 1 - latch mechanism for moving the internal sled; 2, 10 - sliders; 3 - axis of the latch of the internal slide; 4 - latch spring; 5 - latch of the internal slide; 6 - latch lever; 7 - staples; 8 - latch rod; 9 - brackets for the latch of the outer slide; 11 - roller; 12 - guide of the outer slide; 13 - rod of the handle of the movement mechanism; 14 - handle of the movement mechanism
The backrest tilt adjustment mechanism consists of two eccentrics that are turned by a handle. The eccentrics are interconnected by a synchronizer 9 (pic. 169). By turning the eccentrics by the control knob, the gear pairs of internal gearing of the upper 4 and lower 3 links turn the upper links. The latter are welded to the base of the backrest and, when rotated, change the position of the seatback.
Pic. 169. Mechanisms for adjusting the inclination and reclining of the backrest of the front seat: 1 - hook; 2 - hook spring; 3 - the lower link of the backrest tilt adjustment mechanism; 4 - the upper link of the backrest tilt adjustment mechanism; 5 - thrust mechanism for reclining the back; 6 - shells of rods; 7 - handle of the lever of the mechanism for reclining the back; 8 - bracket; 9 - synchronizer
To seat passengers in the rear seat, the backs of the front seats are folded forward, for which the lower links 3 are hinged on the bases of the pillows. In the normal position, the lower links are fixed by hooks 1 under the action of springs 2. When the handle 7 of the tilting mechanism is moved upwards, the rods 5 pull the hooks back and release the lower links, after which it is possible to move the seat back forward.
