Abstract

The invention relates to a device for adjusting a seat back (6) of a vehicle seat (4), in which a drive (9) that carries out adjusting processes is integrated. This acts on stagger gears (10, 22), with which the seat back (6) is moved within a range of inclination (13). A torsion element (24) is provided between the stagger gears (10, 22) that compensates the clearance in the stagger gears (10, 22) within a first range of adjustment (18) of the seat back (6) and functions as support for the driver motor within a further range of adjustment (19) of the seat back (6).
