Two parallel control arms are rotatably disposed on one carriage which, on the other end, are rotatably disposed on a support part. On the other carriage, a link is rotatably disposed which, on the other end, is applied at half length to a parallel control arm. The support part can be lifted vertically by the movement of the carriages.
