Drive coupling for coupling two discs used in a motor vehicle door lock

摘要

The coupling has two coupling discs (2,3) which can turn in relation to one another. One disc has a coupling pin (5) which engages a coupling aperture (4) in the other disc. The coupling disc (2) has a spring lip (6) which is arched (10) towards the coupling aperture and presses the pin against one end or the other end of the coupling aperture depending upon the position of the two discs. One coupling disc may be constructed as a theft prevention power takeoff element (2) and the other coupling disc is constructed as a theft protection disc (3) in the locking system of the door lock.
