ABSTRACT:
A drive device enabling a movable element to be driven by an actuator via a gear system comprising a motor pinion gear, an intermediate gear and a partial toothed gear. An aim of the invention is to create a particularly compact device which can capture the kinetic energy of the actuator in a particularly reliable manner. The intermediate gear comprises a pinion and a toothed gear. The pinion and toothed gear are connected via a ratchet in such a way that the opinion which is rotationally fixed to the ratchet can be rotated counter to the toothed wheel in a manner similar to that of a locking ratchet wheel.
