Patent number: 10618495Abstract: A gas generator is provided, the gas generator having a propellant cushion that prevents movement of propellant wafers, tablets, or grains by providing a bias thereagainst. Furthermore, the cushion may be formed from a polyurethane-based foam material and if desired, a known oxidizer combined within the foam. Channels inherent within the polyurethane-based foam enhance the combustion of the main gas generant. Alternatively, the substituted polyurethane polymer combined with an oxidizer may be formed as a monolithic grain that provides autoignition and gas generant function in lieu of a primary gas generant or in lieu of an igniter composition, for example.Type: GrantFiled: October 28, 2014Date of Patent: April 14, 2020Assignee: Joyson Safety Systems Acquisition LLCInventors: Sudhakar R. Ganta, Dale E. Tauchen, Deborah L. Hordos, Slaven Domazet, Sean P. Burns
