Gasgenerator

摘要

The present invention provides a hybrid gas generator which is capable of keeping an air bag inflated by generating a lower-temperature gas so that the internal pressure of the air bag is maintained following inflation of the air bag. An opening serving as a gas outlet is formed in a cylindrical bottle 22 storing a pressurized medium, and the opening is sealed by a first sealing member 58 which is ruptured by an increase in the internal pressure of the bottle 22 . The increase in the internal pressure of the bottle 22 is produced by activating heating means, and the temperature increase range of the pressurized medium before and after activation is not more than approximately 500° C.
