<p>The system has a control unit i.e. case (5), for controlling backrests (24d, 24g, 24m) of an individual control element i.e. button, that individually controls each backrest. A simultaneous control element i.e. handle, controls all the backrests in a simultaneous manner, where each backrest comprises a tilting mechanism. The individual and simultaneous control elements are articulated around a same axis and are conformed such that movement of the simultaneous control element rotates an assembly of individual control element around the axis.</p> |
