Abstract

A displacement unit for at least one element to be displaced is provided comprising a drive unit, a transfer element that is caused to move by the drive unit and that comprises a thread or a tooth set, and an engagement element, which engages into the thread or tooth set of the transfer element and is thus driven by the motion of the transfer element, and by whose motion the displaced element is moved. The engagement element is configured elastically, in such a way that it deforms elastically upon contact by the displaced element against a stop or obstacle.
