摘要

The system has a locking device for locking a movable unit, and a reversing device for reversing the movable unit into an initial condition. The devices are designed as a construction unit for utilizing synergy effects and an uncomplicated reversing drive. The construction unit has an electric motor (12) and a downstream gear block (13) with a threaded spindle (14) and an axially movable reversing drive nut that is engaged with the threaded spindle, and a locking block (15) with a spring-loaded ratchet (15b) that extends over a threadless borehole in the spindle.
