Abstract
Combustion residues of a gas generating agent remain in an inflator due to composition of the gas generating agent, temperature difference between combustion gas and pressurized gas isolated by a rupturable plate, collision of the combustion gas against a wall surface and the like. The inflator inflates an air bag with pressurized gas and combustion gas, while satisfying the following requirements: (1) pressurized gas contains an inert gas and substantially no oxygen; (2) in the gas generating agent, a pressure is 0.8 or less; (3) a mole ratio of an amount of pressurized gas and the combustion gas is 1 to 10; (4) a ratio of a mass of pressurized gas and the gas generating agent is 1 to 10; (5) a mass of a gas generating agent is 1 to 30 g; and (6) the pressurized gas is charged at 30,000 to 67,000 kPa.
