Abstract
The invention relates to a drive for adjustment devices in motor vehicles, more particularly for vehicle seats, having a stepped switch mechanism acting on both sides for manually producing a rotary movement. The object of the present invention is to provide a simplified and cost-effective device for adjusting the vehicle seat components in two directions. This is achieved by connecting the output side of the stepped switch mechanism to a self-blocking gear.
Claims19
A drive for an adjustment device comprising:
- a stepped switch mechanism having a first side, a second side and an output side and acting on both the first side and the second side to manually produce and transfer a rotary movement, the stepped switch mechanism having a swivel mounted drive lever that produces the rotary movement from a neutral position into at least one rotary direction about a rotary axis, a drive element and at least one coupling element mounted on the drive lever to transfer torque to the drive element;
- and
- a self-locking gear coupled to the drive element to block torque introduced on the output side of the stepped switch mechanism.
