Obstacle detecting device for use in safety assembly, for detecting obstacle inside displacement zone of retractable roof of convertible-type vehicle, has processing unit modulating received signal with control signal
The device has a radiation emitting unit for emitting radiation in a displacement zone. A radiation receiving unit outputs a received signal (SR). A processing unit (4) compares the received signal with a preset reference signal to output a detection signal (SD) indicating a sensed condition or state of an obstacle that is not detected. The processing unit modulates the received signal with a control signal (SC) that represents a position of a retractable roof in the displacement zone. The emitting and receiving units are arranged at a rear side of a passenger compartment of a vehicle. The emitting and receiving units are realized in the form of an ultrasonic-type transceiver (2). Independent claims are also included for the following: (1) a safety assembly (2) a vehicle.
