The air bag inflator is particularly useful for mounting in a steering wheel of a vehicle for inflating an air bag. A magnetic control unit (14) is disposed concentrically of an injection piston (13) through which liquid propellant is injected from a liqui...

The air bag inflator employs an injection piston assembly in which liquid propellant is delivered through nozzles in the injection piston (18) to the combustion chamber (12). Metering of the liquid propellant is accomplished in a manner that is not sensiti...

The variable output inflator includes an injection piston assembly containing a liquid propellant chamber (22) from which liquid propellant is injected through one or more nozzles (25) in the injection piston (18) into a combustion chamber (12). The moveme...

The seat belt module is electronically controlled using magneto-rheological fluid. A CPU delivers a signal to an electromagnetic coil within the module at the beginning of a crash to cause the viscosity of the magneto-rheological fluid to increase sufficie...
