Beschreibung
Zusammenfassung:	The invention relates to a drive device for a hatch of a motor vehicle, wherein the drive device comprises two drive sections that are linearly moveable relative to each other between a retracted position and an extended position, wherein the drive sections are spring biased against each other into the extended position by a spring arrangement, wherein an end stop is provided to limit the drive motion between the drive sections to the extended position. It is proposed that the end stop comprises a damping arrangement with a deformation zone, wherein during a drive motion into the end stop, depending on the speed of the drive motion, the damping arrangement damps the drive motion mainly based on plastic deformation of the deformation zone.
