Abstract
A stored gas inflator is formed by a pressure vessel including a gas port, a small chamber facing the gas port, and a main chamber situated adjacent to the small chamber and having a capacity larger than that of the small chamber. A high pressure gas is filled in the small chamber and the main chamber. A first partition closes the gas port, and a second partition separates the small chamber and the main chamber so that a burst pressure of the second partition is set to be lower than a stored gas pressure in the main chamber. A gas blasting initiator is mounted to the small chamber for applying burst pressure to at least one of the first and second partitions to allow the main chamber to eject the gas.
