Vehicle occupant restraint system

摘要

A source of gas for inflating a vehicle occupant restraint comprises a container. Gas generating material in said container comprises an alkali metal azide and a metal oxidizer. When ignited, the gas generating material produces heated nitrogen gas. A supply of pressurized nitrogen gas is also in the container. Structure is provided for separating the supply of pressurized nitrogen gas from the gas generating material. The separating structure is releasable to enable the heated nitrogen gas and the stored nitrogen gas to commingle. The source of gas also includes structure for directing the stored nitrogen gas and the heated nitrogen gas through a tortuous path toward the vehicle occupant restraint so as to remove particulates from the gases.
