Abstract
The invention relates to an apparatus for interrupting the closing operation of an electric motor driven movable closing element, such as a vehicle sunroof when an obstacle which obstructs the closing operation is detected. A pressure-sensitive sensor strip is arranged on the closing edge of the moved closing part and the sensor signal is transmitted in accordance with the transponder principle by an attenuation modulation of an electromagnetic alternating field. The wireless sensor signal which is thus transmitted controls the control device for the electric drive of the closing part. When an obstacle is detected, the drive is switched off or reversed, depending on the sensed pressure applied to the sensor strip. The sensor strip is preferably implemented by a resistive foil pressure sensor.
