Abstract
A free wheel drive arrangement for a turnable member, especially for adjusting the position of backrests or window panes in automotive vehicles, includes a carrier arm tiltable about the axis of a circular adjusting member and a driving arm eccentrically mounted on the carrier arm for tilting movement with respect thereto between an active position, engaging the turnable member to turn the latter about its axis during turning of the driving arm with said carrier arm in one direction, and a free wheeling position, in which the driving arm is disengaged from the turnable member during turning of the driving arm with the carrier arm in a direction opposite to the one direction. Cooperating abutment means on the driving arm and the carrier arm maintain the driving arm in the free wheeling position during turning of the driving arm with the carrier arm in this opposite direction.
