Elongated inflator device and method of gas production
First Claim
Patent Images
1. An inflator device for inflating an inflatable restraint element, the inflator device comprising:
- an enclosed housing having an elongated length and opposed first and second ends;
a quantity of a gas generant material disposed within the housing, the gas generant material having a non-gaseous, fluid form and substantially extending between the first and second ends of the housing; and
an initiator device disposed adjacent the housing, upon actuation, the initiator device having a discharge portion in reaction initiating contact with at least a portion of the quantity of the gas generant material disposed within the housing;
wherein upon actuation, the initiator device initiates reaction of the gas generant material to produce inflation gas and wherein the housing has sufficient flexibility to permit the inflator device to be shaped to a non-linear elongated axis form.

Abstract
Inflation apparatuses are provided employing an elongated enclosed housing which contains a non-gaseous, fluid form of gas generant material. The housing can desirably be sufficiently flexible to permit the inflator device to be desirably shaped such as to facilitate the specific placement and location thereof within the interior of a vehicle. Also, provided are associated methods of gas production.
