Title:
GAS GENERATOR AND METHOD FOR ASSEMBLING GAS GENERATOR
Document Type and Number:
WIPO Patent Application WO/2018/193672
Kind Code:
A1
Abstract:
In the present invention, a gas generator is provided with: an igniter; a housing accommodating the igniter and having a discharge port connecting the inside of the housing with the outside; and a filling chamber filled with a solid gas-generating agent, the gas-generating agent being placed such that when the igniter is activated, the filled gas-generating agent can combust. The gas generator is also provided, within a prescribed region of the housing including at least the filling chamber, with a pressurized region formed in a prescribed state of airtightness against the outside of the prescribed region and additionally in a state of high pressure. Prior to the igniter being activated, the pressurized region maintains the prescribed state of airtightness, and is demarcated from the outside thereof by means of a sealing member to be split by means of the combustion gas generated by the gas-generating agent when the igniter is activated. The pressurized region is delimited inside the housing by means of region-delimiting members joined via a prescribed intervening member. Due to this configuration, the gas-generating agent placed in the gas generator can be properly protected from moisture without adding to the workload associated with assembling the gas generator.
