Swivelable arm rest for use in a vehicle

An arm rest for arrangement at a seat or a seat bench in a vehicle, includes at least one bracket fastenable to the seat or the seat bench. A bearing shaft is swivelably mounted to the bracket in at least one swivel bearing. The bearing shaft is supported at the bracket so as to be displaceable along a trajectory between an upper functional position and a lower functional position. A support element is connected to the bearing shaft at least at one fastening point in a rotationally fixed manner. The support element can be swiveled between a swiveled-up rest position and a swiveled-down support position. A transmission mechanism is arranged between the support element and the bracket, wherein a swiveling movement of the support element is transmitted via the transmission mechanism to a displacing movement of the bearing shaft along the trajectory. Hereby, modularity of the arm rest is obtained, wherein the variation of the transmission mechanism permits the utilization of an identical support element for different support heights.
