Gas generator
First Claim
1. A gas generator comprising:
- ignition means;
gas generant composition annularly surrounding the ignition means in contact therewith;
a rupturable, hermetically sealed container enclosing the ignition means and gas generant;
an inner housing enclosing the container and having peripheral orifices through which the container may be ruptured for expulsion of gases;
an annular filter inside the container, adjacent the orifices of the inner housing;
an outer housing surrounding the inner housing, defining an annular chamber therewith, and having peripheral orifices for expulsion of gases into an inflatable structure; and
cooling means in the annular chamber between the orifices of the inner and outer housings, so that gases produced by the gas generant may pass therethrough.

Abstract
An electric squib igniter and a gas generant composition surrounding it are enclosed in a hermetically sealed container. This is enclosed in an inner housing which is surrounded by an annular outer housing. An annular filter surrounds the gas generant composition inside the container, which is rupturable through orifices in the inner housing by gases produced when the gas generant composition is ignited. A cooling device in the annular chamber between the two housings is positioned between the orifices of the inner housing and peripheral orifices in the outer housing, through which the filtered, cooled gases may be expelled radially into an inflatable structure. A mounting flange fixed to the outer housing is provided for attachment to related apparatus.
