A device for detection of trapping in a power-operated closing element with a switching element, which is arranged along a first closing edge within an elastic hollow section. The hollow section includes a central area extending longitudinally, in which an active area of the switching element is arranged, and at least one side area extending longitudinally, in which a non-active edge area of the switching element is arranged. The side area has a higher deformability on the side of the hollow section facing the first closing edge than on the central area. The device has a force transmitter extending longitudinally, which transmits a trapping force from the side facing away from the first closing edge to the side area of the hollow section.

Jamming-detection device

A method controls adjustment devices of a motor vehicle seat. The devices are assigned to the longitudinal movement of the seat and the tilting movement of the seat back and are activated by positioning switching elements to move the motor vehicle seat into predetermined set positions. A switching device corresponding with the seat back blocks the associated adjustment device before the seat back runs into an obstacle lying in its range of adjustment. In order to optimize the motion sequences when a rearward tilting movement of the seat back is initiated by one positioning switching element, shortly before the seat back runs into the obstacle, the adjustment device is blocked from further tilting movement of the seat back and a longitudinal movement of the seat forward is automatically initiated by the switching device. The seat back thereby moves out of the switching range of the switching device again, and, in addition to the longitudinal movement of the seat, the rearward tilting movement of the seat back is also continued again, either until the next time blocking occurs or until the set lowered position of the seat back is reached, in which position the longitudinal movement of the seat is then also stopped.
