Publication number: 20170045342Abstract: An integrated barrel/bridge detonator subassembly includes a polyimide flyer layer, a conducting layer, and a barrel layer. The conducting layer has an electrically conducting material laminated to a first side of the flyer layer. The conducting layer consists of a single layer of an electrically conducting material. The electrically conducting material forms a first land having a first connecting pad, a second land having a second connecting pad disposed opposite the first land, and a bridge disposed between and providing electrical conductivity between the first land and the second land. A barrel layer formed of an insulative material is laminated to a second side of the flyer layer substantially opposite the first side. The barrel layer has an opening disposed substantially opposite the bridge.Type: ApplicationFiled: August 10, 2015Publication date: February 16, 2017Inventors: Steven Douglas Fisher, Donald Eugene Warren, John Paul Sparkman

Patent number: 7959185Abstract: An inflator bottle adapted for controlled release of product gas to deploy an inflatable cushion and a method thereof is provided. The inflator bottle comprises a compartment filled with a combustible gas mixture having a partition that divides the compartment into a first region and a second region. Upon a crash event, an igniter on the inflator bottle ignites initiating combustion in the first region. Combustion propagates in the first region toward a nozzle building pressure in the first region sufficient to rupture a burst disk over the passage of the nozzle releasing product gas through the nozzle. The release of product gas through the nozzle draws combustible gas mixture from the second region flowing through the gas portal on the partition into the first region for combustion.Type: GrantFiled: October 1, 2008Date of Patent: June 14, 2011Assignee: Autoliv Development ABInventors: John Paul Sparkman, Charles M. Woods, William H. Phipps

Patent number: 6203061Abstract: The present invention provides variable deployment performance by controlling the heat content of the inflator gas which exits an air bag sub-module, disposed in a module, into an air bag cushion. The air bag sub-module includes a sub-module housing which receives an inflator in a central cavity formed therein. The module housing includes low output module ports formed in the module housing and high output module ports. Heat sinking material is disposed within the sub-module housing between an outer wall of the sub-module housing and the inflator such that the heat sinking material surrounds the low output module ports. The air bag sub-module provides a first fluid flow path for the heated inflator gas to flow under high level deployment conditions and a second fluid flow path for the inflator gas to flow under reduced level deployment conditions. The first fluid flow path comprises a low resistance fluid flow path in which the heated inflator gas exits the inflator through the high output module ports.Type: GrantFiled: October 7, 1999Date of Patent: March 20, 2001Assignee: Delphi Technologies, Inc.Inventors: Robert Raymond Niederman, Allen Richard Starner, Shawn Gregory Ryan, Graham Thornton Spencer, John Paul Sparkman

Patent number: 6196582Abstract: The present invention presents an inflator providing variable output inflation of an air bag cushion in response to full or reduced level deployment conditions. The inflator of the present invention includes a first chamber for storing an inert gas, a second chamber in fluid communication with the first chamber, and a third chamber in selective fluid communication with the second chamber, the third chamber for storing a heat modifier for varying a heat value of the inert gas. The inflator also includes a pyrotechnic device having a combustible material for heating the inert gas and a first initiator for actuating the pyrotechnic device upon first and second deployment conditions. A second initiator for opening the third chamber to the second chamber is provided wherein actuation of the second initiator causing the heat modifier to fluidly communicate with the combustible material and vary the heat value of the inert gas during a combustion process.Type: GrantFiled: September 22, 1999Date of Patent: March 6, 2001Assignee: Delphi Technologies, Inc.Inventors: John Paul Sparkman, Shawn Gregory Ryan, Allen Richard Starner, Robert Raymond Niederman

Patent number: 5803486Abstract: An air bag module includes an inflator and an air bag for inflation upon the discharge of gas by the inflator. The module further includes a mounting and diffuser bracket for securing the inflator and air bag to the vehicle. The mounting and diffuser bracket includes a diffuser portion positioned radially outward of the discharge end of the inflator. The diffuser portion preferably includes wing portions substantially surrounding the discharge ports of the inflator such that upon discharge of gas by the inflator, the wing portions redirect and diffuse the discharging inflator gas into the air bag. Advantageously, the wing portions also provide a localized heat shield for the air bag.Type: GrantFiled: December 17, 1996Date of Patent: September 8, 1998Assignee: General Motors CorporationInventors: Graham Thornton Spencer, James Lloyd Webber, Margaret Ann Fisher, John Paul Sparkman, Mark Harvey Doxey

Patent number: 5700028Abstract: An air bag module includes an inflator for generating inflator gas, an air bag deployable upon generation of inflator gas and secured to the inflator, and a mounting bracket attached to the inflator. The mounting bracket is adapted to secure the inflator to the vehicle. The inflator preferably includes opposing ends and the mounting bracket has a central portion secured to the vehicle. The mounting bracket advantageously includes first and second cantilevered portions, each of the cantilevered portions extending outwardly from the central portion and engaging an end of the inflator. The cantilevered portions each having a predetermined strength such that the cantilevered portions each deform in the direction of the deploying air bag such that the mounting bracket absorbs energy during air bag inflation by predetermined deformation of the cantilevered portions.Type: GrantFiled: May 16, 1996Date of Patent: December 23, 1997Assignee: General Motors CorporationInventors: Jeffrey Allen Logan, John Clifford Hattery, Jr., John Paul Sparkman, David Allan Pray

Patent number: 5690354Abstract: An air bag module includes an inflator for generating gas and an air bag deployable upon generation of gas by the inflator. The module further includes a container for housing the air bag and inflator therein. Preferably, the container is integrally molded as one piece and includes at least two spaced apart integral living hinges. Preferably, the container has a clamshell construction including a first half and a second half pivotally connected to each other by a closure hinge portion. The container preferably includes deployment end portions opposite the closure hinge portion which are releasably connected to each other. Preferably, at least one of the deployment end portions is pivotally connected to the container.Type: GrantFiled: March 19, 1996Date of Patent: November 25, 1997Assignee: General Motors CorporationInventors: Jeffrey Allen Logan, John Clifford Hattery, Jr., John Paul Sparkman, Graham Thornton Spencer, Margaret Ann Fisher

Patent number: 5687987Abstract: An air bag module includes an inflator for generating gas and an air bag deployable upon generation of gas by the inflator. The air bag module further includes a canister for housing the inflator and a clamshell cover for housing the air bag. The clamshell cover is attached to the canister. Preferably, the clamshell cover includes first and second halves and a bendable thin hinge portion pivotally connecting the first and second halves. Upon air bag deployment, the air bag breaks open and deploys out through the hinge portion of the clamshell cover.Type: GrantFiled: February 29, 1996Date of Patent: November 18, 1997Assignee: General Motors CorporationInventors: Graham Thornton Spencer, Margaret Ann Fisher, James Lloyd Webber, John Paul Sparkman
