Abstract
Disclosed is a device comprising a transceiver (9) which transmits HF signals that are reflected back by means of reflectors (6) located in the seats. Diagnostic reflectors (10) are disposed at the edge of the seats in order to diagnose the reflectors (6). Said diagnostic reflectors (10) are disposed such that the diagnostic reflectors are normally not covered up by a person (1) sitting on a seat (2). The diagnosis is carried out at the same time as the person is identified.

10. A device for detecting a position of a person on a seat of a motor vehicle, the device comprising:
-
at least one HF transmitter disposed in a passenger space of the motor vehicle and emitting HF signals;
at least one reflector disposed in the seat for reflecting the HF signals;
at least one diagnostic reflector connected to said reflector for assisting in diagnosing the device; and
an HF receiver for receiving the HF signals and carrying out a diagnosis of the device from a signal transit time between emitting and receiving and/or from a code contained in a received HF signal. - View Dependent Claims (11, 12, 13, 14, 15)

16. A device for detecting a position of a person on a seat of a motor vehicle, the device comprising:
-
at least one HF transmitter disposed in one of a passenger space of the motor vehicle and the seat;
at least one HF receiver disposed in the seat or in the passenger space vice versa of said HF transmitter, said HF transmitter emitting HF signals received and evaluated by said HF receiver with regard to a signal transit time between emitting and receiving and/or from a code contained in a received HF signal; and
at least one diagnostic device, selected from the group consisting of diagnostic transmitters and diagnostic receivers, connected to said HF transmitter or said HF receiver for carrying out a diagnosis of the device. - View Dependent Claims (17)

18. A device for detecting a position of a person on a seat of a motor vehicle, the device comprising:
-
an HF transmitter emitting signals;
a reflector directly or indirectly reflecting the signals and disposed in the seat; and
an HF receiver receiving the signals being received signals, the person on the seat being detected from the received signals by a signal transit time and/or a code contained in the received signals and/or a received intensity, and wherein simultaneously with a detection of the person, a diagnosis being carried out on said HF transmitter, said HF receiver or said reflector by recording and evaluating signal transit times, received signal intensities and/or received codes.
