Abstract
The device has a transceiver which transmits high-frequency signals, which are reflected back by reflectors in the seats. Occupied seats are detected on the basis of signal propagation delays and/or reflector detections and/or receiving intensities. In addition, it is possible to detect with the aid of a belt sensor whether or not a safety belt is fastened.
