Title:
GAS GENERATOR AND GAS DISCHARGE METHOD FOR GAS GENERATOR
Document Type and Number:
WIPO Patent Application WO/2024/005079
Kind Code:
A1
Abstract:
This gas generator comprises: an ignitor; a gas-generating agent that generates combustion gas by combustion caused by activation of the ignitor; a housing in which the ignitor and the gas-generating agent are contained; a gas discharge hole penetrating through the housing; and a metal seal which is formed in sheet shape and is attached to the inner surface of the housing. Prior to activation of the ignitor, the metal seal covers the opening of the gas discharge hole on the inner surface side of the housing and thus closes the gas discharge hole. As the ignitor is activated, the metal seal is cleaved due to the pressure of the generated combustion gas, thereby opening the gas discharge hole. The gas discharge hole includes a chamfered region in which the corner of the opening on the inner surface side of the housing is removed along the circumference.
