Since the actuator always moves in a pivoting of the backrest support, at the same time also performs the support and / or guideway a corresponding movement and therefore influences the change in position of the functional element, without the need for further design measures are required. At the same time, the position and the movement of the functional element on the supporting and / or guideway during pivoting is forced by a link element, which link element is arranged between the functional element and a further structural element of the mechanism.
