Abstract
A hybrid inflator that includes a solid propellant and a pressurized medium comprising oxygen and at least one inert gas is provided. The solid propellant can be fuel-rich in that without excess oxygen it generates significant amounts of CO and H.sub.2. The at least one inert gas is contained in an inflator housing and the amount thereof is greater, on a molar basis, than the oxygen. The propellant has acceptable long-term stability in that such propellant does not ignite when exposed to a temperature of 107.degree. C. for a period of 400 hours.
