Patent number: 9151578Abstract: The invention relates to an unlocking device (10), especially for a vehicle protection device, comprising a locking bar (16) which in a locked position establishes a connection positive at least in portions between a first component (12) to be unlocked and a second component (14) and permits relative motion of the two components (12, 14) in an open position. The unlocking device (10) further comprises a pyrotechnical actuator (18) including a pyrotechnical element (20) having a propelling charge and a piston-cylinder unit (22) having a piston (24) and a cylinder (26), wherein motion of the piston (24) or the cylinder (26) can be generated due to activation of the propelling charge upon ignition thereof and wherein the piston-cylinder unit (22) is connected to the locking bar (16) without redirection so that upon motion of the piston (24) or the cylinder (26) the locking bar is movable from its locked position into its open position.Type: GrantFiled: December 8, 2011Date of Patent: October 6, 2015Assignee: TRW AIRBAG SYSTEMS GMBHInventors: Ernst Enzmann, Achim Hofmann, Rolf Ruckdeschel, Johann Seidl

Patent number: 7665762Abstract: A gas generator for a vehicle occupant restraint system a rigid outer housing (12), a chamber (14) formed in the outer housing (12), in which a compressed gas is present at least upon activation of the gas generator (10), a component immovable (20; 34; 62) relative to the outer housing (12), at least one outflow opening (22) formed in the immovable component (20; 34; 62), and a least one resilient element (26), which is clamped inside the outer housing (12) and rests against the immovable component (20; 34; 62) at least in its normal position. In its normal position, the resilient element (26) closes a flow path between the chamber (14) and external surroundings of the gas generator (10) and is deformed elastically under the influence of compressed gas, whereby it clears a flow cross-section (30) whose size is increasing with increasing pressure.Type: GrantFiled: May 29, 2008Date of Patent: February 23, 2010Assignee: TRW Airbag Systems GmbHInventors: Michael Gabler, Karl Englbrecht, Daniel Kraus, Stefan Labitzke, Thomas Nobach, Helmut Pritz, Johann Seidl

Patent number: 7631888Abstract: A gas generator has a cylindrical gas generator housing (22) and a connecting piece (14) which is welded to the gas generator housing (22). The connecting piece (14) has extensions (28) spaced apart in peripheral direction on the side facing the gas generator housing (22) and has a recess (31) between the extensions (28). The connecting piece (14) is welded to the gas generator housing (22) at the extensions (28).Type: GrantFiled: November 7, 2005Date of Patent: December 15, 2009Assignee: TRW Airbag Systems GmbHInventors: Johann Seidl, Karl Englbrecht

Publication number: 20080296877Abstract: A gas generator, in particular for a vehicle occupant restraint system, has a rigid outer housing (12), a chamber (14) formed in the outer housing (12), in which a compressed gas is present at least upon activation of the gas generator (10), a component immovable (20; 34; 62), at least one outflow opening (22) formed in the component immovable (20; 34; 62) relative to the outer housing (12), and at least one substantially flat, resilient element (26), which is clamped inside the outer housing (12) and rests against the immovable component (20; 34; 62) at least in its normal position. In its normal position, the resilient element (26) closes a flow path between the chamber (14) and external surroundings of the gas generator (10) and is deformed elastically under the influence of compressed gas, whereby it clears a flow cross-section (30) whose size is increasing with increasing pressure.Type: ApplicationFiled: May 29, 2008Publication date: December 4, 2008Inventors: Michael Gabler, Karl Englbrecht, Daniel Kraus, Stefan Labitzke, Thomas Nobach, Helmut Pritz, Johann Seidl

Publication number: 20050156741Abstract: A gas generator or a gas bag module for a vehicle safety system has a signal emitter which is able to be stimulated by an electromagnetic exciter field applied from the exterior or by a magnetic field impulse applied from the exterior, for the emission of a signal. Such signal is detected by means of a manually movable detector (30).Type: ApplicationFiled: January 3, 2005Publication date: July 21, 2005Inventors: Thomas Kapfelsperger, Johann Seidl
