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.
