Abstract

A new and improved single side wall air bag inflator includes a housing containing an ignition device, a quantity of pyrotechnic gas generant material and a filter. The housing includes a cup-shaped base member having an annular bottom wall with a central opening for access to the ignition device and an integrally formed, upstanding ported side wall extends upwardly of the bottom wall. The side wall has a radially inwardly deformable, free upper end portion forming a retaining flange for securing a top wall in place spaced above the bottom wall and closing off an upper end portion of the housing. The top wall has a depressed outer peripheral edge portion facing and sealed with the downwardly and radially inwardly deformed upper end flange of the single side wall.

Claims

1. An air bag inflator including a single side wall housing for containing ignition means, pyrotechnic gas generating means and filter means, comprising:

a cup-shaped base having an annular bottom wall with a central opening for access to said ignition means and an integrally formed, ported, side wall extending upwardly of said bottom wall and having a radially inwardly directed upper end flange;

a top wall spaced above said bottom wall closing off said upper end of said side wall for protectively containing said gas generating means and said filter means and having an outer peripheral edge portion facing and sealed with said upper end flange to close said housing;

ignition means comprising a high energy electrically activated ignition train having a body formed with an outer face closing said central opening of said annular bottom wall;

annular seal means for sealing between said ignition train body and said bottom wall around said central opening;

said ignition means including electrical terminal means projecting from said outer face adapted for interconnection with an external connector having a body with one or more deflectable legs; and

clip means on said bottom wall having an opening for receiving said connector body and an edge portion of said opening adapted to be engaged by a deflectable leg of said body for holding said connector in interconnected relation with said terminal means.

2. The air bag inflator of claim 1, wherein:

said clip means is formed of metal and is secured to said bottom wall by welding.
