Anti-theft seat belt

摘要

The system has a switch (3) positioned within the seat belt buckle receiving mechanism (2) which acts to operate a vehicle disablement device, alarm etc. so that the vehicle cannot be started if the buckle (1) is not in the receiving mechanism. The buckle is secured to the seat belt (7) so that it can be simply removed by the vehicles owner when the vehicle is not in use and replaced when desired. The switch may constitute a simple contact switch (3a,5a,5b) that closes upon the insertion of the belt buckle into the receiving mechanism or may include a more complex system incorporating mechanical key-type teeth or digitized, audio or optical data communication so that the switch of a particular receiving mechanism will only respond to a particular buckle. The buckle may be removable connected to the seat belt either directly, e.g. by having a slot (1b,1c) for receiving the belt, or may be connected to the seat belt via an intermediate element that is permanently connected to the seat belt and which receives and secures the removable buckle portion.
