Abstract

The device has a detent bearing with detent recesses for an articulation axle of a spring (70). A sun gear, a hollow wheel and a slide bearing are coupled with a hand wheel and a drive axle such that the sun gear, the hollow wheel and the slide bearing are driven until the articulation axle is disengaged from one of the recesses, and the sun gear, a planet wheel and a pivoted lever are driven until the articulation axle is adjusted and engaged in the adjacent recess during the actuation of the hand wheel and the drive axle.
