摘要： A method and apparatus compact enough for use in locations, such as in the steering wheel column of a vehicle for inflating a safety device, such as a bag. A stored compressed gas from a stored gas chamber is mixed in a mixing chamber with a combustion gas from a gas generating chamber. A combustion gas barrier between the gas generating chamber and the mixing chamber is designed to rupture when the heat and pressure in the gas generating chamber exceeds a maximum temperature and pressure, allowing combustion gas from a combustible material in the gas generating chamber to flow into the mixing chamber. A hybrid gas barrier between the mixing chamber and an outlet means is designed to rupture when the heat and pressure in the mixing chamber exceeds the maximum temperature and pressure, allowing the gas mixture to flow from the mixing chamber through an outlet means to inflate the safety bag. A strainer disposed between the gas generating chamber and the combustion gas barrier prevents the passage of most of the combustion residue resulting from combustion of the combustible material from the gas generating chamber to the mixing chamber. The gas generating chamber is separate from and outside of the stored gas container, as a result of which the transfer of heat from the combustible material and the combustion gas to the stored gas chamber is minimized.
