Abstract: A headrest for a motor vehicle, including a base part for attachment to a backrest of a vehicle seat, a head part for contact with a head of a vehicle occupant, and an adjusting device between the base part and the head part for causing a substantially linear adjustment of the head part between a minimum and a maximum position. The adjusting device has an intermediate part and several pivot levers which pivot synchronously during adjustment and form a first articulated parallelogram between the head part and intermediate part and a second articulated parallelogram between the intermediate part and base part. The adjusting device includes a synchronizing lever for setting a relative orientation of the head part with respect to the base part during adjustment and wherein the headrest further has a latching device for fixing the headrest in a latching manner relative to the base part.

Abstract: Device for actuating a plurality of actuators (1) in a transportation device, which has a plurality of output stages (2, 3, 4, 5) and a control circuit for actuating the output stages (2, 3, 4, 5), the output stages (2, 3, 4, 5) each connecting through the current in order to activate the actuators (1) and each output stage (2, 3, 4, 5) being connected in electrically conductive fashion to an actuator (1, 9). A plurality of output stages (2, 3, 4, 5) is additionally connected to in each case, one further actuator (1, 9) by the control circuit. The control circuit is actuated in such a way that an output stage (2, 3, 4, 5) can actuate either the first or the further actuator (1, 9) with the output stages (2, 3, 4, 5) being interconnected to one another and/or to the actuators (1, 9) in the manner of a matrix so that a plurality of row lines (6) and a plurality of column lines (7), at whose points of intersection (8) the actuators (1) are arranged, are provided.
