Patent number: 9333937Abstract: Airbag covers with stress relief features are disclosed. An airbag cover includes a cover face that opens during deployment and one or more sidewalls extending from the cover face to engage a housing of an airbag assembly. One or more tear seams formed in the airbag cover are rupturable upon expansion of the airbag to form the cover face as a hinged door that opens. Excess force can cause a tear seam to propagate through a stop, creating a risk that a portion of the airbag cover will separate from itself or the housing. Stress relief features are disposed in a sidewall to dissipate excess deployment energy and limit undesired breakage of the airbag cover or continued tearing of the tear seam beyond a tear seam stop. The stress relief features disclosed include tear seams and slits oriented transverse to front cover tear seams.Type: GrantFiled: December 10, 2014Date of Patent: May 10, 2016Assignee: AUTOLIV ASP, INC.Inventors: Christopher Hock, Mark Hatfield

Patent number: 6394491Abstract: An air bag device that includes an air bag cushion, a diffuser canister, and a gas generation inflator. The diffuser canister is attached to the air bag cushion and has walls configured to define an interior space therein. The walls of the diffuser canister have an interior surface, an exterior surface, and a wall thickness t. At least one of the walls has an aperture formed therethrough in communication with the interior of the air bag cushion. The gas generation inflator is configured to rapidly create a gas that exits the diffuser canister through the aperture so as to fill the air bag cushion. The aperture is defined by an edge extending between the interior and said exterior surfaces of the wall that is configured to diffuse the gas exiting the diffuser canister through the aperture.Type: GrantFiled: January 26, 2001Date of Patent: May 28, 2002Assignee: Autoliv ASP, Inc.Inventors: Quin Soderquist, Michael P.

Patent number: 6213501Abstract: An improved ignition system for vehicle airbags is described. This invention includes a novel means for venting igniter material gases in such a manner as to more evenly distribute the flow in a more disperse manner, thereby permitting the gas generant to burn more uniformly throughout the generant bed. This invention by venting igniter gases more efficiently produces improved airbag ballistics, namely lowered average airbag deployment delay and increased consistency of operation.Type: GrantFiled: March 19, 1998Date of Patent: April 10, 2001Assignee: Autoliv ASP, Inc.Inventor: Christopher Hock

Patent number: 5876062Abstract: A two-walled, dual chamber, inflator for inflation of an automotive airbag in the event of a collision is provided. The inflator includes a simplified housing with two internal chambers, including a central chamber and a coaxial outer chamber. The central chamber houses both the solid fuel gas generant bodies and a electrical igniter having a reliable single-stage ignition train in direct contact with the generant bed. The single-stage igniter includes a resistance wire submersed in the generant bed along a convoluted path. Multiple points of direct contact are established between the igniter wire and gas generant over a substantial portion of the generant bed, which leads to more uniform and efficient ignition of the gas generant. To get sufficient surface area for the generant to contact the igniter wire, the gas generant bodies are formed in relatively small sizes of about 0.05 inch or less, which, in turn, limits the selection of gas generant materials to those having low burn rates of about 0.Type: GrantFiled: July 29, 1997Date of Patent: March 2, 1999Assignee: Autoliv ASP, Inc.Inventor: Christopher Hock

Patent number: 5829785Abstract: A gas generating inflator assembly for a vehicle safety restraint system including an inflator housing having two walls, an inner wall and an outer wall. The inner and outer walls form a combustion chamber therebetween. A filter pack is disposed within the combustion chamber along an inner diameter of the outer wall. Gas generant is also disposed within the combustion chamber. An internal structure is disposed within the combustion chamber for diffusing the ignitor blast and retaining slag produced by the ignited gas generant. The internal structure is spaced from the filter pack and the inner wall such that a portion of the gas generant is located between the internal structure and the inner wall and another portion of the gas generant is located between the internal structure and the filtration pack.Type: GrantFiled: March 26, 1996Date of Patent: November 3, 1998Assignee: Morton International, Inc.Inventors: Michael P. Jordan, Christopher Hock, Matthew A. Cox, Alan J. Ward

Patent number: 5779267Abstract: Components of a vehicle airbag gas generator, or inflator, are coated with reactivity resistant materials to protect them from deterioration caused by contact with the high temperature, reactive gases generated by recently developed non-azide high reactive temperature gas generating materials. Suitable coatings include those produced from ceramics and reactivity resistant metals. These coatings also provide long term protection of the components from deterioration caused by the environment/atmosphere within the inflator.Type: GrantFiled: October 15, 1996Date of Patent: July 14, 1998Inventors: Michael P. Jordan, Alan J. Ward, Christopher Hock, Linda M. Rink
