Abstract
Abstract An adapter permits a cylindrical airbag inflator to be housed in a longer inflator housing, even if the diameter of the inflator varies from optimal. The adapter is in the form of a split tube. One end of the adapter forms a socket receiving the base of the inflator. The other end forms a base which is received in a circular opening in the inflator housing end wall.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
142 words
In a motor vehicle airbag module assembly including a reaction canister, an inflator housing adjoining said reaction canister having a first end defining a keyway and a second end having an outer and an inner surface defining a substantially circular mounting opening, and a substantially cylindrical inflator within said housing having a first end carrying a key supported in said keyway and a substantially circular second end, the improvement comprising: a tubular, substantially cylindrical, adapter having (a) a base end seated within said mounting opening and a flange extending radially outwardly from said base end against said outer surface; (b) a socket end surrounding and gripping the second end of said inflator; (c) an inwardly extending circumferential rib positioned to bear against the second end of said inflator; and (d) a slot extending longitudinally through said adapter to allow radial expansion thereof.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
18 words
The improvement of claim 1 wherein said slot is substantially parallel to a longitudinal axis of said adapter.
Claim 4
Dependent Claim
22 words
The improvement of claim 1 wherein a portion of the socket end gripping the inflator is roughened to enhance the gripping effect.
Claim 5
Dependent Claim
23 words
The improvement of claim 1 wherein the base end of said adapter has a greater outside diameter than that of the socket end.
Claim 6
Dependent Claim
22 words
The improvement of claim 2 wherein a portion of the socket end gripping the inflator is roughened to enhance the gripping effect.
Claim 7
Dependent Claim
23 words
The improvement of claim 5 wherein the base end of said adapter has a greater outside diameter than that of the socket end.
Claim 8
Dependent Claim
123 words
An adapter for retaining an end of a substantially cylindrical automotive airbag inflator within an opening in an inflator housing having a larger diameter than an external diameter of the inflator which comprises: a tubular sidewall, substantially cylindrical about a longitudinal axis, having a base end and a socket end; said base end being positionable within said circular opening and including a flange extending radially outwardly therefrom and adapted to seat against the housing surrounding said opening; said socket end being adapted to surround and grip an end of said inflator; a circumferential rib extending radially inward from said sidewall and positioned to bear against said inflator end; and a slot extending longitudinally through said sidewall to allow radial expansion of said adapter.
Claim 9
Dependent Claim
123 words
An adapter for retaining an end of a substantially cylindrical automotive airbag inflator within an opening in an inflator housing having a larger diameter than an external diameter of the inflator which comprises: a tubular sidewall, substantially cylindrical about a longitudinal axis, having a base end and a socket end; said base end being positionable within said circular opening and including a flange extending radially outwardly therefrom and adapted to seat against the housing surrounding said opening; said socket end being adapted to surround and grip an end of said inflator; a circumferential rib extending radially inward from said sidewall and positioned to bear against said inflator end; and a slot extending longitudinally through said sidewall to allow radial expansion of said adapter.
Claim 10
Dependent Claim
15 words
The adapter of claim 7 wherein said slot is substantially parallel to said longitudinal axis.
Claim 11
Dependent Claim
25 words
The adapter of claim 7 wherein a portion of the socket end adapted to surround the inflator end is roughened to enhance the gripping effect.
Claim 12
Dependent Claim
20 words
The adapter of claim 7 wherein the base end has a greater outside diameter than that of the socket end.
Claim 13
Dependent Claim
25 words
The adapter of claim 8 wherein a portion of the socket end adapted to surround the inflator end is roughened to enhance the gripping effect.
Claim 14
Dependent Claim
20 words
The adapter of claim 11 wherein the base end has a greater outside diameter than that of the socket end.
