The program will develop a control mechanism to install in airbag vents. The device will help alleviate problems with air bag systems. The control valve mechanism will conserve gas as well as regulate the pressure in the airbag. As a result, gas generators can be made smaller without compromising protection in severe crashes. Even more important, the energy absorbing efficiency of the airbag will be substantially improved. Air bag size can then be reduced 50% without a loss in crash protection capability. This reduced size will prevent many airbag induced injuries otherwise inflicted on out of position occupants. For those occupants still exposed to airbag induced injury, the vent valve can be designed to quickly release gas and thereby minimize injury. Deployment velocity can also be lower without compromising system performamce in severe crashes. The vent control will be compatible with other new air bag technologies, including advanced inflators and occupant sensors.
