摘要

The safety and operating unit comprises an electromechanical drive (10) for driving the safety and operating element. The drive has an electric motor (17) with a driven shaft (24), whose rotary movement is converted into a linear or rotary movement of a transmission element (13). The transmission element has a torsion element (20), on which the rotary movement of the shaft is transferred such that it rotates, where the shortening of the torsion element is caused, on which the linear or rotary movement of the transmission element proportionately rests.
