Abstract

A linear drive has a cylinder, a piston guided displaceably in said cylinder, and a pinion. The piston is provided with teeth which can engage into the pinion in order to rotate the pinion upon displacement of the piston. The drive further has at least one deformable element which prevents blocking when the teeth enter into engagement with the pinion.
