In a device for adjusting various parts of an automobile seat, such as its backrest, headrest, etc., there is a switch mechanism (41) with central gearwheel (61) which can be driven by an electric motor. Further gearwheels (101) are arranged distributed at equal distances around the central wheel (61) and can drive the driveshaft for each part to be adjusted. A planetary gearwheel (86) is constantly in engagement with the central gearwheel (61) and is brought selectively into engagement with one of the further gearwheels (101). Only a single electric motor is required for adjusting a plurality of parts.
