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

Patent number: 10118584Abstract: A gas generator contains an anti-vibration, auto-igniting pad. The pad is formed from a mixture of a known auto-igniting composition mixed with an elastomeric polymer, and then cured, thereby forming a polymer—auto-igniting composition matrix. The pad is placed in thermodynamic communication with a housing on the gas generator, thereby enhancing the safety of the gas generator while yet providing a multi-functional pad. The pad is formulated to reduce vibrations when biased against an associated gas generant, while augmenting the amount of gas produced upon gas generator activation, while yet providing an auto-igniting material that is ignited during a high heat event.Type: GrantFiled: June 12, 2017Date of Patent: November 6, 2018Assignee: Joyson Safety Systems Acquisition LLCInventor: Deborah L.

Patent number: 9046327Abstract: A gas generator is provided, the gas generator having a propellant cushion that prevents movement of propellant tablets or grains by providing a bias thereagainst. Furthermore, the cushion is formed from a desiccating material thereby removing moisture and inhibiting moisture uptake by the propellant during manufacture of the gas generator. The elastomeric cushion is also able to manage the presence of chlorine-containing products during periods of inactivation of the gas generator. Accordingly, variables such as fractured propellant and/or moisture retained within the propellant are mitigated or eliminated, thereby enhancing repeatability of inflator performance.Type: GrantFiled: September 29, 2008Date of Patent: June 2, 2015Assignee: TK Holdings Inc.Inventor: Deborah L.

Patent number: 8997655Abstract: A gas generator containing perforate internal chambers, each chamber in vapor communication with at least one other chamber in the gas generator, is provided. When granulated compositions are utilized in one or more of the chambers, permeable materials such as cheesecloth, neoprene, Tyvek™, metal or non-metallic screen, and other suitable fluid permeable materials, may be provided to physically seal the perforations of the various chambers, thereby separating the granulated composition(s) contained therein. In this way, off-gas products formed naturally over time may be effectively managed to ensure expected performance criteria of the associated inflator.Type: GrantFiled: June 4, 2010Date of Patent: April 7, 2015Assignee: TK Holdings Inc.Inventors: Justin W. Ranson, Deborah L. Hordos, Sean P. Burns
