Abstract
An inflator, preferably for an automotive gas bag restraint system, containing a plurality of gas generant bodies which have a relatively inert burn inhibitor coating material thereon. The inhibitor material is preferably a plastic resin. The inhibitor material may also be alumina, titania, silica or a silicate compound,e.g. bentonite. The inhibitors are preferably applied to the generant bodies as a spray. The gas generant may be an azide or a non-azide, preferably an azide and most preferably sodium azide. The inhibited bodies may be any shape, preferably washer-shaped discs in side by side array.
Claims16
A gas bag inflator comprising:
- a combustion chamber having a gas outlet;
- a plurality of gas generant bodies disposed within said chamber, each of said generant bodies being coated with a relatively inert burn inhibitor material which substantially covers only one face and the peripheral walls thereof;
- means for igniting the inhibited bodies;
- and
- means for routing gas generated from said chamber through the gas outlet.
A method of inflating a gas bag comprising igniting a plurality of gas generant bodies disposed within a combustion chamber, each body having a relatively inert burn inhibitor material coating which substantially covers only one face and the peripheral walls thereof, and using the gas generated to inflate the gas bag.
