The adjusting member and the switch means are configured such that the adjusting member causes the switch means to toggle between the first state and the second state.

Abstract: An actuator arrangement for a seat includes a plurality of traction members and an actuator coupled to the plurality of traction members. The actuator has at least one first drive member which is rotatably supported. The actuator may include a second drive member which is supported moveably relative to the at least one first drive member. The traction members are coupled to the at least one first drive member so that rotation of the at least one first drive member gives rise to a cyclical change in the traction applied by the traction members.

Abstract: A lumbar support assembly (2) comprises a support arrangement (3) which may have the form of a wire framework with two side wires (4) and a plurality of transverse wires (6). A Bowden cable arrangement (10) with a single Bowden cable is attached by two plate clips (15, 17) to the two side wires (4). A first end portion (13) of the wire (12) of the Bowden cable arrangement (10) is anchored to a front edge of a seat frame (1), while a second end portion (14) of the wire (12) is coupled to an actuator (20) for adjusting the tension of the Bowden cable. The lumbar support assembly (2) thus requires only one single Bowden cable to arch the lumbar support assembly at least in a lumbar region and to adjust the degree of lumbar support accordingly.
