Abstract

The invention relates to a drive acting on both sides for adjustment devices, including a rotationally mounted drive lever for producing a rotational movement that can be selectively effected in one direction of rotation or in the other direction of rotation, a drive wheel that can only be rotated when the drive lever is moved from a zero point position, at least a one-piece coupling element having two coupling areas for transmitting a torque to the drive wheel, in addition to a sliding block guide with areas for controlling the coupling element. The coupling element can be displaced radially and is tiltably mounted in a guide and coupled by both coupling areas in the zero point position of the drive lever to the drive wheel in an elastic manner so that the non-loaded coupling area is uncoupled from the drive wheel by the sliding block guide when the drive lever moves from the zero point position and remains uncoupled when the drive lever moves in the opposite direction.

Dependent claims

A drive acting on both sides for an adjustment device, comprising:

a swivel mounted drive lever for producing a rotary movement which starting from a zero point position of the drive lever can take place selectively into a first rotary direction and into a second opposite rotary direction;
a drive wheel which is rotated during movement of the drive lever out from the zero point positions;
at least one coupling element mounted on the drive lever and having two coupling areas for transferring torque to the drive wheel;
and
a sliding block guide with sliding block guide areas for controlling the at least one coupling element,
wherein the at least one coupling element is mounted radially displaceable and able to tilt in a coupling element guide and is coupled spring elastically with the drive wheel through the two coupling areas in the zero point position of the drive lever so that during movement of the drive lever out from the zero point position at least one of the coupling areas is non-loaded and is uncoupled from the drive wheel through the sliding block guide and during movement of the drive lever in the direction of the zero point position remains uncoupled.
