ABSTRACT:
A first deceleration sensor operates switches for energizing the release element of airbags in a vehicle, typically glow wires that will set off an explosive filling of the respective airbag. Connected through diodes to the various airbags is a circuit in parallel with the release elements of all of them which contains a fuse 49 in series with a normally closed switch 50, which last is controlled by a second deceleration sensor 52. If a short circuit or any malfunction causes any one or more of the airbags to release, since the sensor controlling the normally closed switch does not operate, the fuse blows to register a false release. The sensor controlling the normally closed switch may also control a normally open switch in series with all of the switches controlling individual airbags, so that both sensors must operate to release an airbag, and is economically combined into a mercury switch unit in which rapid deceleration moves the mercury to break one circuit and make another circuit, as distinguished from the first-mentioned sensor which operates switching transistors.
