On VAZ-21083, 2109, 21093 cars, the rear seat may differ only in the shape of the cushion and back padding.
To increase the area of the luggage compartment of all the cars in question, the rear seat folds; for this, the pillow and backrest are hinged to the body on hinges. Movable hinge links are welded to the bases of the pillow and back; each of the fixed hinges is bolted to the body. The cushion hinges are covered with plastic facings. The back of the seat additionally has a plastic panel at the back, which is covered with a black carpet, common with the luggage compartment carpet. The carpet is made of lightweight non-woven material with a polyethylene backing.
In the normal position, the seat cushion and backrest are locked with locks. The pillow lock consists of a latch, a body welded to the floor under the pillow, a lock body and a latch with a drive. The body is welded to the base of the pillow, and a spring-loaded latch is installed on its body on the axis, which engages with the latch. To lift the pillow, it is necessary to pull the nylon tape of the lock drive connected to the latch and disengage the latch from the latch. When the cushion is lowered, the latch is automatically locked with a latch.
The seat back locks are screwed to the base. In the body of each lock there is a spring-loaded tongue, which is pressed into the groove of the latch fixed to the body frame. To reduce noise, the end of the tongue is covered with plastic. A rod with a fixing plastic holder is connected to the second end of the tongue through the hole. The rods of the right and left locks are connected to the common lever of their drive locks. The lever is mounted on the axis of the body, which is attached to the base of the backrest with two screws.
When the lever is turned to the left, the right and left rods retract the tongues, releasing the latches, after which the seat back can be laid in place of the pillow, thereby increasing the area of the luggage compartment. When the backrest is raised to its normal position, it will automatically lock with locks.
On VAZ-2109 and 21093 cars, when folding the rear seat, so that the armrests of the rear doors do not interfere, they must be open.
