Estimating the term…
A vehicle safety apparatus (10) for use in inflating an inflatable vehicle occupant protection device (12) comprises a pressure vessel (14) for containing a combustible mixture of gases. A combustible mixture (18) of gases is contained within the pressure vessel. The combustible mixture (18) of gases comprises a combustible fuel gas mixture, an oxidizer gas for supporting combustion of the fuel gas mixture, and an inert gas. The fuel gas mixture comprises hydrogen gas and a hydrocarbon gas. The hydrogen gas comprises about 84 to about 96 molar percent of the fuel gas mixture. The hydrocarbon gas comprises about 4 to about 16 molar percent of the fuel gas mixture. An actuatable igniter (12) is provided for igniting the combustible mixture (18) of gases in the pressure vessel (14). Gas is enabled to flow from the pressure vessel (14) into the vehicle occupant protection device (12).
Apparatus for use in inflating an inflatable vehicle occupant protection device, said apparatus comprising:
A combustible mixture of gases comprising a fuel gas mixture, an oxidizer gas for supporting combustion of said fuel gas mixture, and an inert gas, said fuel gas mixture comprising about 84 to about 96 molar percent hydrogen gas and about 4 to about 16 molar percent hydrocarbon gas based on the moles of fuel gas mixture.
