Patent number: 7556284Abstract: A variety of embodiments are disclosed, in both apparatus and method form, that relate to the use of fabric material in the manufacture of an air bag deployment system. In addition, fabric weakening is disclosed according to a technique that does not result in physical alteration of the fabric. This invention therefore includes an air bag cover for an air bag safety system for a vehicle comprising a fabric outer layer having a frontside and a backside and a substrate containing an opening wherein the opening has a periphery. The substrate is preferably formed by low pressure molding, wherein the fabric outer layer overlies the opening in the substrate, and wherein the fabric outer layer is weakened at a location that is adjacent or overlies the substrate opening periphery.Type: GrantFiled: August 18, 2006Date of Patent: July 7, 2009Inventors: Keith A.

Patent number: 7156415Abstract: An air bag door construction for air bag deployment comprises a trim panel and air bag door of unitary construction, at least a portion of the door defined by an area of reduced cross-section outlining at least a portion of the periphery thereof. One or more tethers are formed in the panel, outlined by an area of reduced cross-section, preferably in a dovetail shape which does not direct the propagation of tearing into the tether. A tear stop may be formed at the ends of the tether. The improvement comprises a stiffening frame that is attached to the backside and/or the topside of the panel just outboard of the air bag door periphery but not located across the tethers to improve deployment performance.Type: GrantFiled: May 6, 2004Date of Patent: January 2, 2007Assignee: Collins & Aikman Products Co.Inventors: John D.

Patent number: 6976701Abstract: An airbag door system is provided comprising a substrate, an outer shell and a foam where all three layers possess a line of mechanical weakness with each line of mechanical weakness at least partially separating each layer into an airbag door portion and a trim member portion. The substrate line of mechanical weakness comprises at least one substrate aperture. The outer shell line of mechanical weakness comprises an outer shell reduced thickness portion defined by an outer shell sever extending partially through an outer shell thickness from an outer shell lower surface towards an outer shell upper surface. The foam line of mechanical weakness comprises a foam reduced thickness portion defined by a foam sever extending partially through a foam thickness from a foam lower surface towards a foam upper surface.

Patent number: 6955376Abstract: An apparatus for deploying an air bag through an automotive dash panel (12) includes an air bag door (16) integrally formed in the panel and defined by a door perimeter including a frangible edge (18) of reduced cross section. A dispenser (20) supports the air bag (24) behind the door. A metal reaction plate (28) is positioned between the air bag (24) and the door (16). When the air bag inflates, it forces the reaction plate (28) to bend around a horizontal hinge line (36). As the reaction, plate pivots it concentrates inflation force along a lower portion of the frangible door edge. This helps to predictably separate the door from the dash panel by tearing along the lower door edge and allowing the tear to propagate up two side edges. In one embodiment, the tear also propagates across an upper edge to completely separate the door from the panel. At least one, and preferably two or three tethers (50) limit how far the door can travel during air bag inflation.Type: GrantFiled: June 16, 1999Date of Patent: October 18, 2005Assignee: Collins & Aikman Products Co.Inventors: Craig B. Labrie, Edwin V. Stawicki, Nelson J. Morren, John J. Kennedy, Vernon A. Daniels, Jimmy C. Rogers, John D. Gray, Bruce A. Batchelder, Michael J. Gallagher, Richard D. Rhodes, Jr.

Patent number: 6655711Abstract: An air bag cover assembly is provided comprising a retainer panel having an aperture during the deployment of an inflatable air bag for the airbag to pass through. The aperture has a cross-sectional area during air bag inflation greater than the cross-sectional area of the aperture when the air bag is deflated after being inflated. A method of providing an air bag deployment aperture for an air bag cover assembly is also provided. The method comprises providing a retainer panel, forming an aperture in the retainer panel for the deployment of an inflating air bag from an air bag module, increasing the cross-sectional area of the aperture during inflation of the air bag, and decreasing the cross-sectional area of the aperture after the air bag has at least partially passed through the aperture.Type: GrantFiled: October 27, 2000Date of Patent: December 2, 2003Assignee: Textron Automotive Company, Inc.Inventors: Craig B.

Patent number: 6633019Abstract: A method for forming a design in a panel includes providing an outer panel layer on an inner panel layer to form a single composite panel including two layers. The design is then formed into the panel by forming voids in the outer layer. The voids are formed by exposing predetermined regions of the outer layer to a laser beam that burns, vaporizes or otherwise removes portions of the outer layer in each exposed region. The voids create the design by exposing the inner panel layer.Type: GrantFiled: November 27, 2001Date of Patent: October 14, 2003Assignee: Textron Automotive Company, Inc.Inventor: John D. Gray

Patent number: 4950346Abstract: An apparatus and method are disclosed for holding a generally cylindrical workpiece for honing or otherwise machining an internal bore. The workpiece is held by a gripping surface over most of the innermost turn of a spirally wound spring and coil. The workpiece is grasped circumferentially over its outer surface without excess contact pressure at any particular point. A tendency of the machining operation to rotate the workpiece serves to secure the workpiece more tightly in position by tightening the outer turns of the spring band coil. A rotatable tensioning member acts under the influence of a biasing spring to decrease the diameter of the innermost turn of the spring band coil to bring the gripping surface into contact with the workpiece. A method for adapting the work-holding apparatus to smaller or irregularly shaped workpieces consists of molding an annular piece around the workpiece.Type: GrantFiled: February 14, 1989Date of Patent: August 21, 1990Inventor: Harold A.
