Title:
GAS GENERATOR
Document Type and Number:
WIPO Patent Application WO/2019/225298
Kind Code:
A1
Abstract:
A gas generator provided with: a housing; an igniter disposed inside the housing; a combustion chamber in which the igniter is housed and which is filled with a gas-generating agent that is burned by said igniter; gas discharge holes that are provided in the housing and connect the interior and the exterior of the housing; and a cylindrical filter disposed between the combustion chamber and the gas discharge holes. In the generator, the filter is positioned inside the housing so that a portion of at least one end face of the two end faces of the filter in the axial direction is in contact with and supported thereby, and an outer area located to the outside, in the radial direction, of said contact-supported area adjoins a specified space while a specified outer circumferential area of the outer circumferential surface of the filter near the at least one end face is in contact with and supported thereby. As a result of such a configuration, it is possible to inhibit combustion gas short paths in gas generators equipped with a filter.
