Device for the interlocking of two positively guided elements adjustable relative to one another

A device for the interlocking of two positively guided elements adjustable relative to one another in an interlocking position, in which the elements are connected so as to be adjacent to one another, in particular for the interlocking of a part covering a vehicle orifice with the vehicle body, in which one element forms a carrying element for a guide mechanism with an interlocking member, in which the other element is provided as counterelement with a countermember, in which the interlocking member is capable of being transferred via the guide mechanism out of a position of readiness for grasping the countermember into an interlocking position for the grasped countermember, said interlocking position corresponding to the interlocking position of the elements, and in which the guide mechanism is connected to an actuating drive, wherein the interlocking member (31), in its position of readiness, is blocked against adjustment by the actuating drive (33) in the direction of its interlocking position and is capable of being transferred out of this blocking position via the counterelement (35), when the latter approaches the interlocking position of the elements (34, 35), into a position enabling adjustment via the actuating drive (33) in the direction of the interlocking position.
