Abstract
First and a second sealing layers are provided inside an inner periphery of a casing layer having a plurality of gas ejecting bores in its outer peripheral wall, and a gas-generating agent is mounted between the sealing layers, while a compressed gas is filled inside the second sealing layer. When the gas-generating agent is fired due to a collision of a vehicle, the first sealing layer is cleaved in a region of the gas ejecting bores by the pressure of a generated combustion gas and, then, the second sealing layer is cleaved likewise in a region of the gas ejecting bores by the pressure of the compressed gas, thereby permitting the compressed gas to be ejected uniformly from the plurality of gas ejecting bores into an air bag. In this case, a reduction in temperature of the compressed gas due to an adiabatic expansion thereof is compensated for by mixing of the compressed gas with the combustion gas, thereby enabling an efficient expansion of the air bag.
