Abstract
A device (10) for detecting a belted condition for a seat belt system (12) of a motor vehicle (14) is presented. The device (10) comprises at least one transceiver (24) for electromagnetic waves as well as a transponder (28) and a controller (30). The first transceiver (24) is disposed, when viewed in the vehicle longitudinal direction (L), in front of or behind the sitting position of a vehicle occupant (16) and is connected to the controller (30) so as to transmit signals. The transponder (28) is arranged on webbing of the seat belt system (12) associated with the vehicle seat (19) and is configured to receive and automatically respond to scanning signals of the transceiver (24). The controller (30) is configured to detect, based on output signals of the first transceiver (24), whether the vehicle occupant (16) has correctly fastened the seat belt (18). Furthermore, a method for detecting a belted condition is suggested.
