摘要： A hybrid inflator comprises a housing formed of welded-together metal stampings defining a toroidal gas chamber surrounding a center tie and storing pressurized gas therein. The center tie has a generally cylindrical sidewall and an outlet wall at an upper end thereof defines a rupturably sealed outlet orifice. An inverted stamped metal cup is matingly received in the center tie. The lip of the cup is welded to the lower end of the center tie, and the cup sidewall is circumferentially grooved for separating a sliding piston portion under pressure. A squib support wall and squib closes the lower end of the center tie and inverted cup to define a combustion chamber containing a pyrotechnic gas generant which, upon ignition, causes the inverted cup to separate at the groove and drive the sliding piston upwardly to an open position uncovering inlet openings from the combustion chamber to the gas storage chamber. Hot gasses from the combustion chamber flow into the gas storage chamber and the outlet orifice rupturably opens permitting stored gas and combustion products to exit the inflator. The sliding piston and center tie are tapered to control movement of the piston by friction and deformation, together with lanced limit stop tabs. The cup has a convex bottom, deformation portions and may carry a lance to open the orifice. A baffle provides a surface on which incomplete products of combustion are collected and captures debris. A deformable outlet diffuser provides compact packaging.

摘要： A hybrid adaptive airbag inflator. The inflator includes two separate chambers, each containing a quantity of stored inert gas. Each chamber additionally includes a heating device to heat the stored gas. To provide adaptive performance, one, or the other, or both of the heating devices may be fired, depending upon the severity of the collision. The heated stored gas increases in pressure and breaks free of the chamber to inflate the cushion. The two chambers are preferably provided with restricted gas communication, to equalize pressure between the chambers over time. This restricted communication maintains the chambers essentially separate over the short time periods associated with inflation. Over time, however, the communication will permit any unfired chamber to depressurize, providing increased safety.

摘要： The invention facilitates fixedly attaching to vehicle steering wheels different or variously styled driver restraint modules, while incorporating common major module components. For example, three (3) different modules use the same major module components (reaction plate, inflator, and folded air bag) but utilize different brackets for steering wheel mounting and adaptation to the styling locations of selected ones of the variously styled driver module assemblies for horn blowing, speed control, etc. This makes it possbile to use more common production tooling, i.e., for cover attachment, bag folding, etc., thus enabling manufacturing cost reduction.

The subassembly contains a quantity of pyrotechnic material and at least in part defines a combustion chamber wherein at least a portion of the quantity of pyrotechnic material is reactable to form product gas for inflation of an associated airbag cushion and to generate pressure therewithin. A diffuser assembly can be disposed adjacent an end of the shell member and includes flow control features for controlling flow of product gas from the inflator assembly. The inflator assembly further includes a composite overwrap about at least a portion of the subassembly and the diffuser assembly such that the pyrotechnic inflator assembly can withstand the pressure generated within the combustion chamber upon reaction of the pyrotechnic material. Corresponding methods of making a pyrotechnic inflator assembly are also provided.

摘要： A fire suppression apparatus that includes a housing defining a first chamber containing a gas generant. The apparatus further includes an initiator operatively associated with the first chamber and in reaction initiating communication with the gas generant. The initiator, upon actuation, acts to ignite at least some of the gas generant to form gas. The housing further defines a second chamber adjacently disposed to the first chamber. The second chamber contains an endothermically-alterable material and a piston assembly including a piston. Upon actuation, the piston moves to expel at least a portion of the endothermically-alterable material from the second chamber such that the expelled endothermically-alterable material contacts and cools gas formed by the ignition of the gas generant. The housing further has at least one discharge opening to permit cooled gas to exit the housing. Corresponding or associated methods for suppressing a fire are also provided.
