摘要

The invention relates to a drive mechanism which acts on both sides, for producing a turning movement for manually adjusting the height or angle of an automobile seat. The drive lever is coupled with locking means. Said locking means are able to engage with a toothing arrangement located on the periphery of a drive wheel. According to the invention, the locking means have a single piece tilting element (2, 2a, 2b, 2c) which tilts back and forth between two end positions, depending on the drive direction. In each end position, the tilting element (2, 2a, 2b, 2c) interlocks with the toothing arrangement (401, 401a, 401b, 401c) of the drive wheel (4, 4a, 4b, 4c). The inventive drive mechanism is characterised in that it has a low number of individual parts, is easy to assemble and has a compact construction.
