Patent number: 11040692Abstract: An airbag inflator includes a pressure vessel with a bottom portion, a top portion and a center structure connecting the bottom portion and the top portion. The top portion includes an exit orifice that is closed with a rupturable membrane. An energetics cover attached to the center structure houses a pyrotechnic material, and a diverter is attached to the top portion. The pressure vessel, the energetics cover and the diverter define a gas flow path from inside the energetics cover toward the bottom portion of the pressure vessel, the gas flow path turning at least a first 180 degrees toward the top portion of the pressure vessel and between the energetics cover and the pressure vessel. The longer gas flow path allows time for multi-perforation grain slivers to burn up before exiting the inflator, thereby reducing the amount of particulate exiting the inflator.Type: GrantFiled: August 22, 2019Date of Patent: June 22, 2021Assignee: ARC Automotive, Inc.Inventors: Scott Lohmann, Rebekah Reid, James Rose, Robert Zimbrich

Patent number: 10953838Abstract: The invention relates to an airbag system for a vehicle, including a first airbag and a second airbag situated largely above the first airbag in the intended main supporting direction. Both airbags may be triggered chronologically. In the airbag system both airbags may include a separate gas supply and may effectively interact to provide a larger airbag volume without substantial loss of time. When both airbags are activated, the second airbag deploys largely on the surface of the first airbag. Due to the separate gas supply, both airbags may be triggered simultaneously and independently of one another. It is also possible for only the second airbag to be triggered and for the first airbag to remain inactive. Thus, the airbag system covers a wider range of load conditions. The system helps by allowing the vehicle occupants more freedom in choosing their sitting positions.Type: GrantFiled: February 13, 2018Date of Patent: March 23, 2021Assignee: Audi AGInventor: Tobias Skrodzki

Patent number: 10906848Abstract: A method of manufacturing and optimizing energetic propellant grains includes generating an optimal surface area to mass fraction burned ratio profile for a predetermined solid structure including propellant grains; using the profile as a target function of a topological optimization process to generate a 3D form of a propellant grain; developing a negative of the 3D form of the propellant grain; mixing and densifying the negative with an energetic material in an uncured form in a mixer to create a structure including the energetic material and embedded negative; and solvating the negative from the structure, wherein the negative comprises a 3D propellant grain. The developing of the negative of the 3D form of the propellant grain may occur using a predetermined material in an additive manufacturing process. The negative may be soluble in the predetermined material, and the energetic material may be insoluble in the predetermined material.Type: GrantFiled: March 23, 2017Date of Patent: February 2, 2021Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Paul J. Conroy, Raymond A. Wildman, Eric J. Robinette, John R. Schmidt, Andrew T. Gaynor
