Air Bag System

View page
US Patent:
7448648, Nov 11, 2008
Filed:
Feb 23, 2006
Appl. No.:
11/360638
Inventors:
Scott D. Thomas - Novi MI, US
James M. Kumkoski - Utica MI, US
Assignee:
GM Global Technology Operations, Inc. - Detroit MI
International Classification:
B60R 21/16
US Classification:
2807432
Abstract:
An air bag system housed within a cavity includes an inflator, an inflatable air bag, and an air bag housing defining a vent. A deployment door movable between a closed position and an open position at least partially covers the cavity. A vent restrictor is movable between a first position and a second position. In one of the first and second positions, the vent restrictor at least partially blocks the vent to restrict venting of inflation fluid therethrough. In the other of the positions, the vent restrictor leaves the vent substantially open. The vent restrictor is operatively connected to the deployment door or the air bag. When connected to the deployment door, movement of the deployment door from the closed position to the open position moves the vent restrictor. When connected to the air bag, inflation of the air bag moves the vent restrictor.

Air Bag With A Supported Channel

View page
US Patent:
7484757, Feb 3, 2009
Filed:
Dec 8, 2005
Appl. No.:
11/297038
Inventors:
Scott D. Thomas - Novi MI, US
James M. Kumkoski - Utica MI, US
Assignee:
GM Global Technology Operations, Inc. - Detroit MI
International Classification:
B60R 21/16
US Classification:
2807432
Abstract:
An air bag system includes an inflator operable to release inflation fluid, and an inflatable cushion having an lower region and inflatable upon release of inflation fluid from the inflator, with the cushion defining a channel within the lower region thereof. At least one tether may support the channel during inflation of the cushion. A fabric member may at least partially cover the channel to define an end channel wall. The fabric member may detach from the cushion if the cushion inflates beyond a predetermined depth, or the fabric member may be movable between a first position and a second position to increase the area of the end channel wall. A retention member may retain the fabric member in the first position. The retention member may be frangible, such that inflation of the cushion beyond the predetermined depth breaks the retention member.

Air Bag System

View page
US Patent:
7591482, Sep 22, 2009
Filed:
Feb 16, 2006
Appl. No.:
11/356344
Inventors:
Scott D. Thomas - Novi MI, US
James M. Kumkoski - Utica MI, US
Assignee:
GM Global Technology Operations, Inc. - Detroit MI
International Classification:
B60R 21/239
US Classification:
280739, 2807432
Abstract:
An air bag system includes an inflator, an inflatable air bag, and a vent opener operatively connected to the air bag and selectively movable from a first position to a second position to create a cushion vent within the air bag for venting inflation fluid. A movable member operatively connects to an air bag housing, with a retention member extending through a connector arm to selectively connect the movable member and the vent opener. A sensing tether is operable to selectively release the retention member. The air bag system may further include a switch, with a sensing tether operable to change the state of the switch if any portion of the air bag passes a predetermined plane during inflation thereof.

Simplified Inflatable Restraint Module

View page
US Patent:
55337503, Jul 9, 1996
Filed:
Jun 1, 1995
Appl. No.:
8/456568
Inventors:
James P. Karlow - Milford MI
James M. Kumkoski - Clarkston MI
Mohamed Boumarafi - Rochester Hills MI
Jonathan P. Hurford - Lake Orion MI
Assignee:
Takata, Inc. - Auburn Hills MI
International Classification:
B60R 2118
US Classification:
2807302
Abstract:
An inflatable restraint module especially adapted for seat mounted side impact protection. The restraint module incorporates a retainer bracket with projecting deformable tab fingers which are loaded inside the bag through an access slit. Slots on opposite sides of the access slit are overlapped and placed such that the retainer bracket tab fingers extend through them. A sheet metal mounting bracket is then installed over the air bag. A cylindrical inflator is installed through holes formed in the mounting bracket and air bag into the interior cavity of the retainer bracket. This sub-assembly can be mounted into a plastic housing having slots which permit the tab fingers to extend to the exterior of the housing where they can be deformed to interlock the components in an assembled condition.

Process For Manufacturing A Gas Generating Material

View page
US Patent:
49990632, Mar 12, 1991
Filed:
Jun 7, 1990
Appl. No.:
7/535116
Inventors:
Thomas H. Vos - Rochester MI
James M. Kumkoski - Utica MI
Leo S. Knowlden - Gilbert AZ
George W. Goetz - Rochester Hills MI
Assignee:
TRW Vehicle Safety Systems Inc. - Lyndhurst OH
International Classification:
D03D 2300
US Classification:
1491096
Abstract:
A wet mixture of a metal azide having a predetermined average particle size and a metal oxide is prepared. The wet mixture is ground to reduce at least the average particle size of the metal azide. Thereafter, the wet mixture is directed through a chamber containing grinding media. The grinding media is agitated as the mixture flows through the chamber to further reduce the average particle size of the metal azide to a desired particle size.

Spheronizing Process

US Patent:
50842188, Jan 28, 1992
Filed:
May 24, 1990
Appl. No.:
7/528150
Inventors:
Thomas H. Vos - Rochester MI
James M. Kumkoski - Utica MI
Leo S. Knowlden - Romeo MI
George W. Goetz - Rochester Hills MI
Assignee:
TRW Vehicle Safety Systems Inc. - Lyndhurst OH
International Classification:
C06B 2100
D01D 000
US Classification:
264 34
Abstract:
A process for making a body of gas generating material comprising the steps of preparing a slurry of the ingredients of said gas generating material; extruding said slurry into a plurality of extrudate; forming the extrudate into spherical granules; and pressing a plurality of granules to form a unitary body.

Process For Manufacturing A Gas Generating Material

View page
US Patent:
49942123, Feb 19, 1991
Filed:
May 24, 1990
Appl. No.:
7/528144
Inventors:
Thomas H. Vos - Rochester MI
James M. Kumkoski - Utica MI
Leo S. Knowlden - Gilbert AZ
George W. Goetz - Rochester Hills MI
Assignee:
TRW Vehicle Safety Systems Inc. - Lyndhurst OH
International Classification:
C06B 2100
US Classification:
264 33
Abstract:
A process for manufacturing a gas generating material includes preparing a wet mixture of a metal azide and a metal oxide without prior mixing of the metal azide and metal oxide in dry form. The metal azide content of the gas generating material is controlled and the possibility of forming hazardous hydrazoic acid fumes is minimized by maintaining the temperature of the wet mixture of gas generating material between 20. degree. C. and 30. degree. C. The possibility of forming hydrazoic acid fumes is further reduced by maintaining the pH of the wet mixture of gas generating materials at or above 10. 5. Excess liquid is removed from the wet mixture of gas generating materials so that the wet mixture has a moisture content of approximately 9%. The excess liquid from the wet mixture is recycled and used the formation of additional gas generating material. The wet mixture of gas generating materials, having a moisture content of approximately 9%, is formed through small openings to form extrudate of gas generating material.

Auto-Ignition Device For An Air Bag Inflator

View page
US Patent:
51674262, Dec 1, 1992
Filed:
Dec 17, 1991
Appl. No.:

Inventors:
Joseph J. Mihm - North Branch MI
James M. Kumkoski - Mesa AZ
Assignee:
TRW Vehicle Safety Systems Inc. - Lyndhurst OH
International Classification:
B60R 2132
US Classification:
280735
Abstract:
An air bag inflator is provided with a new and useful auto-ignition device. The auto-ignition device comprises a thermoelectric battery, preferably located outside of the inflator housing. The thermoelectric battery is adapted to become electrochemically active in a predetermined temperature range (e. g. 300. degree. -400. degree. F. ), and to provide an electrical signal which actuates the inflator.
