Abstract

A vehicle occupant restraint system (10) has an anti-theft feature. A restraint device (e.g., 12) of the system (10) is actuatable for restraining a vehicle occupant. The restraint device (12) has an identity associated with the system (10). A central controller (40) communicates with the restraint device (12) and controls actuation of the restraint device. The central controller (40) has a theft deterrent function (52) for discerning the identity of the restraint device (12) and for determining whether the identity of the restraint device corresponds to the system (10). The theft deterrent function (52) provides a signal (60) indicative of the determination.

11. A system as set forth in claim 10 wherein said restraint device includes a memory that stores an identification key, the identification key is the identity of said restraint device.

12. A system as set forth in claim 11 wherein said control means includes a memory that stores an identification key of said control means, said means for determining includes means for comparing the identification key of said restraint device with the identification key of said control means.

13. A system as set forth in claim 11 wherein said memory of said restraint device is non-volatile.

14. A system as set forth in claim 11 wherein said memory of said restraint device is programmable read-only memory.

15. A system as set forth in claim 10, including means for providing an alert in response to said signal from said control means indicating that said restraint device does not correspond to said system.

16. A system as set forth in claim 15 wherein said means for providing an alert includes means for providing at least one of an audible or visual signal.

17. A system as set forth in claim 10, including means for recording information about said restraint device in response to said signal from said control means indicating that said restraint device does not correspond to said system.

18. A system as set forth in claim 10 wherein said restraint device is one of a plurality of actuatable restraint devices included in said system, each of said plurality of restraint devices has an identity associated with said system, said control means further communicates with said plurality of restraint means and controls actuation of said plurality of restraint devices, said control means includes means to discern the identity of each of said plurality of restraint means and for determining whether the identities of said plurality of restraint devices correspond to said system, and said signal provided by said control means is indicative of the determination regarding the identities of said plurality of restraint devices.

19. A system as set forth in claim 10, including a communication interconnection interconnecting said control means and said restraint device for conveying a control signal from said control means to said restraint device to cause actuation of said restraint device and an identity signal from said restraint device to said control means to provide the identity of said restraint device to said control means.

20. A system as set forth in claim 19, including sensor means for sensing a condition indicative of a vehicle crash and for providing a signal indicative thereof, said communication interconnection further interconnects said control means and said sensor means for conveying said signal from said sensor means to said control means.
