Abstract
A drive device ( ) with an actuating drive ( ) for driving a movable element ( ), in which drive device a lever ( ) coupled to the movable element ( ) is capable of being driven by the actuating drive ( ) via a gear ( ), the lever ( ) being capable of being acted upon by a firmly supported return spring ( ) so as to be capable of being pivoted back into a basic position ( ), and, in the basic position ( ), a first lever arm ( ) of the lever ( ) being acted upon by a stop ( ), is to have a particularly low space requirement and at the same time absorb momentum energy of the gear ( ) in a particularly reliable way in the event of a failure of the actuating drive ( ). For this, the first lever arm ( ) of the lever ( ) is subdivided by a clearance ( ) into a first part region ( ) and a second part region ( ), the first part region ( ) and the second part region ( ) each having a free end ( ), and at least the free end ( ) of the second part region ( ) being deformed in the direction of the free end ( ) of the first part region ( ).
