Abstract

A drive device includes a screw-and-nut system comprising a threaded rod and a first nut that is connected to the threaded rod by means of a screw connection; a gearset, allowing a rotational movement to be transmitted to the threaded rod, a first toothed wheel and a second toothed wheel engaged with the first toothed wheel; a set of stops comprising a first stop connected to the first wheel rotating about an axis of rotation of the first wheel and a second stop connected to the second toothed wheel rotating about an axis of rotation of the second wheel, the first stop and the second stop being configured and arranged to butt against one another so as to limit an angular travel of the threaded rod at a first angular position in a first direction.
