Abstract
An inflator of a vehicle occupant protection system contains an elongated housing having a plurality of gas exit orifices spaced along the length thereof. An ignition body and propellant are provided in lengths substantially equivalent to the length of the housing wherein the ignition body is placed in physical contact with the propellant body for all or most of their respective lengths. Once the ignition body is ignited upon a crash event, resultant uniform ignition and combustion across the length of the propellant results in uniform gas generation and uniform inflation of an airbag , wherein the airbag is at least substantially coextensive with and in fluid communication with the housing . Preferred mixtures of propellant contain silicone, a perchlorate oxidizer, and a coolant.
