Drive device

Abstract

A drive device (10, 100) with an actuating drive (40, 130) for driving a movable element (11, 110), in which drive device a lever (62, 144) coupled to the movable element (11, 110) is capable of being driven by the actuating drive (40, 130) via a gear (48, 132), the lever (62, 144) being capable of being acted upon by a firmly supported return spring (34, 164) so as to be capable of being pivoted back into a basic position (82, 161), and, in the basic position (82, 161), a first lever arm (64, 146) of the lever (62, 144) being acted upon by a stop (84, 160), is to have a particularly low space requirement and at the same time absorb momentum energy of the gear (48, 132) in a particularly reliable way in the event of a failure of the actuating drive (40, 130). For this, the first lever arm (64, 146) of the lever (62, 144) is subdivided by a clearance (68, 150) into a first part region (70, 152) and a second part region (72, 154), the first part region (70, 152) and the second part region (72, 152) each having a free end (74, 76, 156, 158), and at least the free end (76, 158) of the second part region (72, 154) being deformed in the direction of the free end (74, 156) of the first part region (70, 152).
