Title:
AIRBAG EXPANSION GAS GENERATOR
Document Type and Number:
WIPO Patent Application WO/1996/035595
Kind Code:
A1
Abstract:
The present invention relates to an airbag expansion gas generator for use in expanding by means of combustion gas an airbag such as an airbag for a collision safety device, a lifesaving bag, a rubber boat and an escape chute, and aims at drastically simplifying the construction of a generator when compared with conventional ones and facilitating a reduction in the size of a generator. In the present invention, combustion gas produced by virtue of the combustion of a gas generating agent (43) is caused to flow out directly into an airbag from a gas outlet port (61) formed in an outer circumferential wall (45) of a combustion chamber (41) after it passes through a gas filtration filter (67) disposed inside the outer circumferential wall (45). Then, when it passes through the gas filtration filter (67), residues in the combustion gas are captured by the gas filtration filter (67) and the combustion gas is cleaned. In addition, in the present invention, since the flow path of combustion gas produced by virtue of the combustion of the gas generating agent (43) is changed by means of a flow path changing means (73), residues (81) in combustion gas are captured between a partition member (71) and the flow path changing means (73) before the combustion gas flows in the gas filtration filter (67), and thereafter the gas is cleaned by means of the gas filtration filter (67) and the gas so cleaned is then caused to flow out from a gas outlet port (61).
