Abstract
Abstract An adapter and retainer secures a hybrid inflator within the reaction canister of a passenger-side airbag module. It attaches to, or is integral with, the end wall of the canister and includes a cup which receives the nozzle end of the inflator. Surrounding the cup is a gas-impermeable flange. The flange includes compressive force means for applying clamping force to the inflator parallel to its longitudinal axis while resisting pressure buildup from within the canister during inflator actuation.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
183 words
In an automotive airbag module including a trough-shaped reaction canister having first and second end walls; an elongated, substantially cylindrical, inflator having a longitudinal axis and extending from a first end positioned adjacent said first end wall to a second end engaging said second end wall and having a gas discharge outlet at one of said first and second ends; and means for securing the first end of said inflator to said first end wall, the improvement wherein said securing means comprises: a cup in circumferential press-fit engagement with the first end of said inflator and coaxial with said longitudinal axis, said cup including a base receiving and holding the first end of the inflator; a substantially annular mounting plate surrounding said cup and integral with said first end wall; and a flange surrounding the cup and extending from said cup to said mounting plate to provide gas-impervious connection therebetween, including at least one compressive force member resistant to gas pressure buildup within said canister, whereby said inflator is compressively retained between said end walls and gas leakage from said canister is minimized.
Claim 2
Dependent Claim
183 words
In an automotive airbag module including a trough-shaped reaction canister having first and second end walls; an elongated, substantially cylindrical, inflator having a longitudinal axis and extending from a first end positioned adjacent said first end wall to a second end engaging said second end wall and having a gas discharge outlet at one of said first and second ends; and means for securing the first end of said inflator to said first end wall, the improvement wherein said securing means comprises: a cup in circumferential press-fit engagement with the first end of said inflator and coaxial with said longitudinal axis, said cup including a base receiving and holding the first end of the inflator; a substantially annular mounting plate surrounding said cup and integral with said first end wall; and a flange surrounding the cup and extending from said cup to said mounting plate to provide gas-impervious connection therebetween, including at least one compressive force member resistant to gas pressure buildup within said canister, whereby said inflator is compressively retained between said end walls and gas leakage from said canister is minimized.
Claim 3
Dependent Claim
21 words
The improvement of claim 1 wherein said improvement includes fastening means for attaching said mounting plate to said first end wall.
Claim 4
Dependent Claim
23 words

Claim 5
Dependent Claim
21 words
The improvement of claim 3 wherein said improvement includes fastening means for attaching said mounting plate to said first end wall.
Claim 6
Dependent Claim
18 words
The improvement of claim 1 wherein said gas discharge outlet is at the first end of said inflator.
Claim 7
Dependent Claim
21 words
The improvement of claim 5 wherein said improvement includes fastening means for attaching said mounting plate to said first end wall.
Claim 8
Dependent Claim
23 words
The improvement of claim 5 wherein said compressive force member comprises a thickened ring formed in said flange and surrounding said longitudinal axis.
Claim 9
Dependent Claim
21 words
The improvement of claim 7 wherein said improvement includes fastening means for attaching said mounting plate to said first end wall.
Claim 10
Dependent Claim
196 words
In an automotive airbag module including a trough-shaped reaction canister having first and second end walls; an elongated, substantially cylindrical, inflator having a longitudinal axis and extending from a first end positioned adjacent said first end wall to a second end engaging said second end wall and having a gas discharge outlet at one of said first and second ends; and means for securing the first end of said inflator to said first end wall, the improvement wherein said securing means comprises: a cup in circumferential press-fit engagement with the first end of said inflator and coaxial with said longitudinal axis, said cup including a base receiving and holding the first end of the inflator; a substantially annular mounting plate surrounding said cup and integral with said first end wall; and a flange surrounding the cup and extending from said cup to said mounting plate to provide gas-impervious connection therebetween, including a plurality of radially disposed ribs formed in said flange and surrounding said longitudinal axis as compressive force members resistant to gas pressure buildup within said canister, whereby said inflator is compressively retained between said end walls and gas leakage from said canister is minimized.
Claim 11
Dependent Claim
196 words
In an automotive airbag module including a trough-shaped reaction canister having first and second end walls; an elongated, substantially cylindrical, inflator having a longitudinal axis and extending from a first end positioned adjacent said first end wall to a second end engaging said second end wall and having a gas discharge outlet at one of said first and second ends; and means for securing the first end of said inflator to said first end wall, the improvement wherein said securing means comprises: a cup in circumferential press-fit engagement with the first end of said inflator and coaxial with said longitudinal axis, said cup including a base receiving and holding the first end of the inflator; a substantially annular mounting plate surrounding said cup and integral with said first end wall; and a flange surrounding the cup and extending from said cup to said mounting plate to provide gas-impervious connection therebetween, including a plurality of radially disposed ribs formed in said flange and surrounding said longitudinal axis as compressive force members resistant to gas pressure buildup within said canister, whereby said inflator is compressively retained between said end walls and gas leakage from said canister is minimized.
