SUBSTANCE: vehicle seat consists of the seating part (1), the seat back (2) and the first and second locking devices (7). The angle between the seating part (1) and the seat back (2) is adjustable. The back (2) consists of the base (3) and the upper portion (4). The upper portion (4) of the seat back is pivotable with respect to the base (3) of the seat back. The first locking device makes it possible to fix the inclination of the seat back base (3) relative to the seating part (1) in two positions by means of a control lever (6) which mechanically controls the first locking device. The second locking device (7) makes it possible to fix the inclination of the seat back upper part (4) relative to the base (3) of the seat back in two positions. The switch (8) is integrated into the control lever (6). The switch (8) controls the second locking device (7) and for this purpose is in active connection with one pneumatic control element (9) and a pneumatic actuating element (10).
EFFECT: improved convenience of adjusting the seat back angularly with a shoulder tightening.
