ABSTRACT:
A coupling has a first coupling part comprising a holding rod which is provided with a groove for the engagement of locking balls. The locking balls are radially movably arranged in transverse bores of a holding element arranged on a second coupling part. In a non-operative position of the rollover bar, the locking balls are pressed by a cone surface of a locking member into the groove of the holding rod. If the locking member is displaced in a sensor-controlled manner axially against the effect of a spring by an electromagnet, the holding rod is released. To achieve a construction which is as compact as possible and which permits a housing of the coupling also in the very limited space conditions in a motor vehicle, the holding element with the locking balls and the locking member are arranged inside the electromagnet.
