Patent number: 9376086Abstract: An airbag module having a first shell (10) forming a first gas chamber (GI), a first inflator for the first gas chamber (GI), an adaptive influencing device for influencing the ventilation or shape of the first gas chamber (GI), and an actuation unit (40) for the influencing device. The actuation device (40) has a second shell (44) forming a second gas chamber (G2), and a gas source. The state of the influencing device changing upon actuating the gas source. A tensioning element having a first end (62) is coupled to the adaptive influencing device or forms the device, and a second end (64) is coupled to the second shell (44) when the second gas chamber (G2) is not filled and is decoupled from the second shell (44) when the second gas chamber (G2) is filled.Type: GrantFiled: August 12, 2013Date of Patent: June 28, 2016Assignee: AUTOLIV DEVELOPMENT ABInventors: Raimund Nebel, Nico Wallat, Zang Holger, Roland Peiz, Alexander Rottach, Jürgen Knauss, Andreas Förge, Wolfgang Drössler, Jens Hoffmann, Marcus Weber, Michael Burger

Patent number: 7745745Abstract: A pyromechanical disconnecting device, in particular for battery shutoff in a motor vehicle include a housing (1) in which there is arranged a conductor bus (11) that is designed to be severable by a cutting chisel (12) at a predetermined cut point, the cutting chisel being capable of being accelerated by the propellant gases of an ignition element (2). In order to facilitate assembly it is proposed that the housing (1) be extruded around the ignition element (2), which in this way forms one structural unit with the housing (1).Type: GrantFiled: April 30, 2004Date of Patent: June 29, 2010Assignee: Delphi Technologies, Inc.Inventors: Gerhard Kordel, Jurgen Knauss

Patent number: 7222561Abstract: A pyromechanical cutting element has a housing (2) in which an electrical conductor (3) is arranged, a cutting plunger (5) with a cutting tool (8) to cut through the electrical conductor (3), and pyrotechnic charge (13) to drive the cutting plunger (5), with the cutting tool (8) bending over the electrical conductor (3) after cutting through it and forming a bending tongue (18) that sticks out from the conductor (3) in a way that interrupts the conductor (3). The electrical conductor (3) has a cross-sectional area reduction in the longitudinal direction (4) consisting of two transverse sides and two longitudinal sides. The cutting tool (8) first cuts through the cross-sectional area reduction (4) just on one transverse side and upon further advancement bends over the longitudinal sides at least in part, and, upon further advancement, the cutting tool (8) clamps the bending tongue (18) thus created.Type: GrantFiled: February 2, 2004Date of Patent: May 29, 2007Assignee: Delphi Technologies, Inc.Inventors: Uwe Brede, Gerhard Kordel, Jurgen Knauss, Reinhold Meisinger

Patent number: 7205879Abstract: The invention relates to a pyromechanical disconnecting device having a housing (2) in which an electrical conductor (3) is arranged, having a cutting plunger (5) and a cutting chisel (8) made of plastic arranged thereon for severing the electrical conductor (3), and having a pyrotechnic igniter (1) in which a pyrotechnic charge is arranged for driving the cutting plunger (5), the cutting chisel (8) having an edge that slides along a mating edge of the housing (2) or of a component (4) of the housing (2) when the cutting plunger (5) or the cutting chisel (8) is driven and when the electrical conductor (3) is severed. In order to achieve better cutting power, it is proposed that the edge of the cutting chisel (8) and/or the mating edge of the housing (2) or of a component (4) of the housing (2) comprise an inserted structural element (6, 7) having a greater hardness than plastic.Type: GrantFiled: June 28, 2004Date of Patent: April 17, 2007Assignee: Delphi Technologies, Inc.Inventors: Gerhard Kordel, Jurgen Knauss

Patent number: 7182012Abstract: A pyrotechnic cutting device has a guiding housing in which there is arranged a part to be severed, which is fashioned so as to be severable at a cut point by a cutting tool having a cutting chisel. A pressure pulse generator containing a pyrotechnic driving charge is arranged in the cutting device for generating a pressure pulse to drive the cutting tool. In the guiding housing there is arranged, between the pressure pulse generator and the cutting tool, an impact capsule that can be accelerated by the pressure pulse of the triggered pressure pulse generator toward an inner thrust base of the cutting tool on the end of the cutting tool opposite to the cutting chisel. The cutting tool has its cutting chisel abutting the cut point before the impact capsule strikes the thrust base.Type: GrantFiled: July 29, 2004Date of Patent: February 27, 2007Assignee: Delphi Technologies, Inc.Inventors: Uwe Brede, Jurgen Knauss, Diedrich Von Behr

Patent number: 7111558Abstract: The invention relates to a pyrotechnic detonator with an igniter support of plastic, which bears an ignition element. A cylindrical metal housing is fastened to the igniter support, into which the ignition reaches. A booster charge is arranged in the metal housing. To improve seal tightness and lower the manufacturing costs, for mechanical support a metal insert is integrated into the igniter support, the metal insert being encased by the plastic of the igniter support.Type: GrantFiled: January 30, 2003Date of Patent: September 26, 2006Assignee: Delphi Technologies, Inc.Inventors: Uwe Brede, Eduard Berenz, Anton Bretfeld, Harald Frank, Jurgen Knauss

Patent number: 7078635Abstract: A pyromechanical disconnecting apparatus, in particular for battery shutoff in a motor vehicle, includes a housing (4) in which there is arranged an electrically conductive conductor bus (2), which is fashioned so as to be severable at a predetermined cut position (1) by a cutting chisel (6) driven by a pyrotechnic propellant charge. The conductor bus (2) is clamped in on its side facing away from the cutting chisel (6) by a locking bolt (5) inserted into the housing (4), and a receiving space (15) is arranged in the locking bolt (5) in the region of the predetermined cut position (1), into which receiving space the cutting chisel (6) bends the region of the conductor bus (2) severed by it, and the locking bolt (5) forms an external surface of the housing (4).Type: GrantFiled: April 2, 2004Date of Patent: July 18, 2006Assignee: Delphi Technologies, Inc.Inventors: Gerhard Kordel, Jurgen Knauss
