Inflator for a vehicle air bag assembly and a method of making the same

A method of making an inflator (10) for an air bag assembly includes the step of providing a first housing member (12) having a recess (22) and a second housing member (14) having a coupling portion (24). One of the housing members, preferably the first housing member (12), includes a container (20)...

Summary:A method of making an inflator (10) for an air bag assembly includes the step of providing a first housing member (12) having a recess (22) and a second housing member (14) having a coupling portion (24). One of the housing members, preferably the first housing member (12), includes a container (20). A source of inflation fluid (18) is loaded into the container (20). The second housing member (14) is positioned so that its coupling portion (24) is adjacent to, but outside of, the recess (22). The coupling portion (24) is then mechanically deformed towards the recess (22) to form an integral projection (26) which is tightly received within the recess (22). In this manner, the first housing member (12) is coupled to the second housing member (14) to form a closed chamber (16) containing the source of inflation fluid (18). In the inflator (10) according to the present invention, the coupling portion (24) has a deformation pattern consistent with the coupling portion (24) being initially positioned entirely outside the recess (22) and then being mechanically displaced towards the recess (22) to form the projection 26.
