ABSTRACT:
In order to symmetrically act on a support member (20) of a support assembly on both sides using a single Bowden cable (18), a traction cable arrangement is used with comprises the Bowden cable, a first traction wire (17), and a coupling device (16) for coupling the first traction wire (17) to the Bowden cable (18). The first traction wire (17) is fixedly attached to the coupling device (16) and extends therefrom in a first direction. The sheath of the Bowden cable (18) is fixedly attached to the coupling device (16), and the wire of the Bowden cable (18) extends from the coupling device (16) in a second direction substantially opposite to the first direction and forms a second traction wire (19). The first traction wire (17) and the second traction wire (19) are slidably held on the support member (20) and are connected to a seat frame (30) at their ends. When the wire of the Bowden cable (18) is retraced with respect to the sheath, the second traction wire (19) is shortened, the coupling device (16) is displaced in the extending direction of the second traction wire (19), whereby a tensile force is also generated in the first traction wire (17). Consequently, the first traction wire (17) and the second traction wire (19) symmetrically act on the support member (20) on both sides thereof.
