A gas generatorincludes an autoignition composition that contains an alkali metal chlorate such as potassium chlorate as an oxidizer, a carboxylic acid such as DL-tartaric acid as a fuel, and a desiccant in operable communication therewith. Gas generating systemssuch as vehicle occupant protection systems, containing the gas generator, are also provided.

Autoignition compositions

An airbag inflator () including an elongated outer housing () having an interior and a plurality of orifices () extending collinearly therealong to enable fluid communication between the outer housing interior and an exterior of the outer housing (). The outer housing orifice(s) () open from the outer housing interior toward a first side (F) of the inflator. An elongated inner housing () is positioned in the outer housing interior. The inner housing () has an interior and a plurality of orifices () extending collinearly therealong to enable fluid communication between the inner housing interior and an exterior of the inner housing (). The inner housing orifice(s) () open from the inner housing interior toward a second side (S) of the inflator. A quantity of a gas generant composition () extends along a portion of the interior of the inner housing (). The gas generant composition () has a substantially 'C'-shaped cross-section with a slot () extending along the length of the gas generant composition (). The gas generant slot () is oriented facing the inner housing orifice(s) (). The slotted, 'C'-shaped cross section of the gas generant () provides a greater exposed gas generant surface area than would be achievable without the slot (). This enhances the ignition and burning of the gas generant composition () upon inflator activation.
