    摘要: A housing for a gas generating composition comprises an igniter chamber for retaining an igniter material. A combustion chamber is formed around the igniter chamber, and a gas generating composition is disposed in the combustion chamber. A cooling chamber with a gas exhaust port is formed around the combustion chamber. A coolant for cooling gas is accommodated in the cooling chamber. The igniter chamber, the combustion chamber and the cooling chamber communicate with one another through ports. A first shell constitutes the top wall of the combustion chamber, an intermediate wall between the combustion chamber and the cooling chamber, and at least the bottom wall of the cooling chamber. The first shell is integrally formed of a metal plate with an even thickness, and opens downward at its center portion and is open at least upward at its outer surface. An igniter housing constitutes at least the peripheral wall of the igniter chamber. The igniter housing is joined to the inner surface of the top wall of the first shell, and is open downward. A second shell is open downward, and is joined to the first shell at the periphery of the opening. The second shell and the first shell cooperate to define the cooling chamber. A cover is joined to the first shell and the igniter housing to constitute the bottom walls of the igniter chamber and the combustion chamber.
