US Patent 7905516 Airbag module with integrated gas generation

An airbag module integrates the components required for gas generation, thereby eliminating the need for a separate inflation component. The airbag module can comprise a cover with a pocket, a gas generant container, an inflatable cushion an upper and lower retainer housing, and an inflation gas generation system in fluid communication with the cushion. The airbag module does not comprise a discrete inflator that is functional outside the assembled airbag module. The gas generant container houses a package of solid gas generating compound. The energetic materials of the propellant do not become functional as a gas generation source until the cover is secured to the lower retainer housing.
