Abstract

The invention relates to a device for occupant protection in a motor vehicle and for anti-theft protection of the motor vehicle, comprising an airbag (3), which may be inflated with gas by means of a filling device, a transceiver (5), for electromagnetic waves (6) and an occupant protection analytical unit (81) connected thereto. An occupant protection interrogation unit (41) is arranged on the inflatable airbag (3), which is wirelessly interrogated by the transceiver (5). Information on the degree and/or speed of unfolding of the airbag is thus provided to the occupant protection analytical unit (81). The transceiver (5) may furthermore wirelessly interrogate a portable anti-theft interrogation unit (42), for example, a chipcard and hence provide an anti-theft analytical unit (82) with information about the authorisation of the anti-theft interrogation unit (42) and/or the separation of the anti-theft interrogation unit (42) from the transceiver (5) based on the returned signal.
