Gas forming igniter composition for a gas generant
First Claim
1. In a method of generating gas suitable for use in the inflation of an airbag cushion of an inflatable restraint system of a motor vehicle wherein a gas generant composition is ignited with the reaction products of a boron fuel and oxidizer-containing igniter composition, the improvement wherein said igniter composition includes at least about 15 composition weight percent boron and additionally comprises at least about 15 composition weight percent of an organic gas-producing fuel component.
