Abstract
A gas generator contains a housing having a first end and a second end; a perforated first combustion chamber contained within the housing; a first gas generant contained within the first combustion chamber; a first gas generant cushion positioned between one of either the first end or the second end, and the first gas generant; and a booster chamber contained within the housing, the booster chamber extending through the first gas generant cushion to physically communicate with the second end of the housing. The gas generant cushion may have at least one concave cavity formed on one side of the cushion for providing an enhanced propellant cushion. A vehicle occupant protection system incorporating this gas generator is also contemplated in accordance with the present invention.
