Abstract:
A supplemental-restraint-system gas generating device for use in a vehicle, said gas generating device comprising:a sensor for sensing impact to the vehicle and generating an impact signal;a squib which is operatively associated with the sensor to receive the impact signal from the sensor and which is activated by the impact signal;an igniter which comprises at least one extruded dry igniter element and is operatively associated with the squib so as to be ignited by the activated squib; anda gas generant composition in operative relation to the igniter so that the igniter, in an ignited state, initiates combustion of the gas generant composition to cause the gas generant composition to generate gas for inflating an air bag,wherein said extruded dry igniter element is formed from an extrudable igniter composition comprising, as ingredients prior to drying of said composition to form said dry igniter element, at least one water-soluble binder dissolved into an aqueous solution, at least one oxidizing agent, at least one fuel, and, optionally, fibers, and wherein said water-soluble binder comprises at least one member selected from the group consisting of a water-soluble polymeric binder, a water-soluble gum present in an amount of from about 2% by weight to about 10% by weight based on the total amount of dry ingredient in said extrudable igniter composition, and water-soluble gelatin.
