ABSTRACT:
A seat component of an adjustable seat, particularly of a motor vehicle seat, is mounted on a base component for movement generally in the forward and rearward direction of the seat. A toothed rack is rigidly mounted on the seat component, and a pinion member is mounted on a driving shaft and meshes with the toothed rack. A driving element of a disk-shaped configuration is rigidly connected to the driving shaft and has a plurality of circumferentially distributed openings which receive corresponding tooth-shaped projections of the pinion member to entrain the pinion member for joint rotation with the driving shaft. The pinion member is displaceable axially of the driving shaft to engage the tooth-shaped projections in, and disengage the same from, the corresponding openings of the driving element. A spring urges the pinion member axially of the driving shaft toward the driving element, and a threaded member is mounted on a hub of the pinion member and abuts an end face of the driving shaft to determine the axially displaced position of the pinion member relative to the driving shaft. The driving shaft may be the output shaft of a motor, or the disk-shaped driving element may have a circumferential annulus of teeth thereon with which a pinion mounted on the output shaft of the motor meshes.
