Abstract
The invention relates to a device for a seat height adjustment mechanism of a vehicle seat, comprising a drive element which can be driven in opposite directions of rotation, and a driven element which can be driven by means of this drive element, and also comprising two unilaterally acting freewheels which are arranged between this drive element and this driven element and are connected to run in opposite directions, and of which in each case one can be brought out of engagement by means of an unlocking device, and further comprising a restoring device, by means of which the drive element can automatically be brought back into the neutral position when it is deflected out of its neutral position, wherein, in order to allow a fine adjustability of the driven element driven by the drive element, the pivotability of the drive element is limited by means of two stops.
