Publication number: 20060043716Abstract: A gas generating system (10) includes a tubular outer housing (12) having a longitudinal axis (L) and one or more apertures (12d) formed therealong to enable fluid communication between an interior of the outer housing and an exterior of the outer housing. A tubular inner housing (70) is positioned within the interior of the outer housing (12). The inner housing (70) includes one or more apertures (70d ) formed therealong to enable fluid communication between an interior of the inner housing and an exterior of the inner housing. A first tubular baffle (80) is provided for cooling and regulating a flow of gas produced by the gas generating system (10). The first baffle (80) has a plurality of corrugations (80c) formed therealong and is positioned between the inner housing (70) and the outer housing (12) to define a gas flow channel (82) extending between the first baffle (80) and the inner housing (70).Type: ApplicationFiled: August 30, 2005Publication date: March 2, 2006Inventors: Eduardo Quioc, David Whang, Paresh Khandhadia

Publication number: 20060016362Abstract: A gas generating system (10) including a filter assembly (36) formed from a plurality of nodules (36b) positioned and secured in relation to each other so as to form a porous structure (36a). In one embodiment, the nodules (36b) are metallic and are secured in relation to each other using either a sintering process or a brazing process. The nodules (36b) may be bonded directly together, or the nodules may be secured within a metallic matrix material. The gas generating system may also include a first baffle plate (40) positioned between the plurality of nodules (36b) and a gas source of the gas generating system (10), and a second baffle plate (42) positioned between the plurality of nodules (36b) and a housing wall (12c) of the gas generating system (10).

Patent number: 5763814Abstract: The invention relates to an electrical initiator which can be used with an automobile air bag or seat belt pretensioner. The initiator comprises a header, a cup, conducting pins, epoxy pin seals, a bridgewire, a primer, and an output charge. The header and the cup are composed of an insulating dielectric material capable of being ultrasonically welded together. The header secures the pins. Each pin is electrically conductive and each is formed with a buttress knurl to form a seal when each pin is inserted into the header. Additionally, the pins are further sealed to the header by an epoxy sealant. The bridgewire connects the pins together on one side of the header. An electrical signal through the bridgewire generates heat igniting the primer. Primer reacts with the output charge that in turn ignites a solid gas generant that produces gas that fills air bags or activates the gas generator that drives seat belt pretensioners. The primer contacts the bridgewire. The output charge contacts the primer.Type: GrantFiled: October 9, 1996Date of Patent: June 9, 1998Assignee: Quanti Industries, Inc.Inventors: Mark Lucas Avory, William David Fahey, Stewart Shannon Fields, Charles Joyce Moore, Jr., Charles John Piper, III, David Whang

Patent number: 5454320Abstract: An air bag initiator including a main body and squib. The squib includes a charge mounted in a charge holder, a header press fitted onto the charge holder and a cup welded to the header. The squib also includes first and second lead pins and a bridgewire. A cap snap fits onto the main body and holds the squib in place during subsequent assembly operations. Ferrite beads for frequency attenuation and potting material are located in a cavity of the main body. The first lead is mounted off center in a bore passing through the header to allow bridgewires of different lengths to be used with the same header design. The cup includes a depression to maintain a single explosive powder charge under pressure and in contact with the bridgewire. An outer cup can be welded to the housing and an insulating cup can be provided between the cup of the squid and the outer cup to provide enhanced hermetic sealing of the charge and prevent current from passing between the cups.Type: GrantFiled: October 23, 1992Date of Patent: October 3, 1995Assignee: Quantic Industries, Inc.Inventors: Lynn G. Hilden, Charles J. Piper, III, David Whang, Mark L. Avory, Theodore J. Netoff
