Patent number: 9840224Abstract: An inflator for a protective device in a vehicle includes a diffuser (10) forming a substantially rotation-symmetric external housing of the locator with a closing member (12), wherein the diffuser (10) includes a plurality of discharge orifices (78) arranged in a row, and which are of circular shape. The inflator also includes a circumferential wall (16, 22) which surrounds a combustion chamber (44) and a filter (46) which extends at least partially along the wall (16, 22), wherein the wall (16, 22) has at least one supporting portion (124) which constitutes an axial support for the filter (46) and is integrally formed with the wall (16, 22), and wherein either plural supporting portions (124) are formed by embossed beads, the heads being spaced apart from each other in circumferential direction, and wherein a supporting portion (124) is formed by a completely circumferential embossed bead.Type: GrantFiled: November 3, 2015Date of Patent: December 12, 2017Assignee: TRW Airbag Systems GmbHInventors: Sebastian Bierwirth, Achim Hofmann, Hans-Peter Neumayer, Dieter Spitzenberger, Hannes Nuiding, Thomas Schober, Josef Bommer, Tobias Breddermann, Dietmar Schwebel

Patent number: 9815431Abstract: An inflator for a protective device in a vehicle includes a diffuser (10) forming a substantially rotation-symmetric external housing of the inflator with a closing member (12), wherein the diffuser (10) includes a plurality of discharge orifices (78) arranged in a row, and which are of circular shape. The inflator also includes an igniter sleeve (38) which at least partially encloses an igniter (34) and an igniter chamber (42) filled with a booster charge and is adjacent to a first combustion chamber (44) filled with fuel, wherein the igniter sleeve (38), related to a central axis B of the igniter sleeve (38), has overflow orifices (98) unevenly distributed in circumferential direction.Type: GrantFiled: November 3, 2015Date of Patent: November 14, 2017Assignee: TRW AIRBAG SYSTEMS GmbHInventors: Sebastian Bierwirth, Achim Hofmann, Hans-Peter Neumayer, Dieter Spitzenberger, Hannes Nuiding, Thomas Schober, Josef Bommer, Tobias Breddermann, Dietmar Schwebel

Patent number: 9643564Abstract: An inflator for a protective device in a vehicle includes a diffuser (10) forming a substantially rotation-symmetric external housing of the inflator with a closing member (12), wherein the diffuser (10) includes a plurality of discharge orifices (78) arranged in a row, and which are of circular shape. The inflator also includes a combustion chamber sleeve (60) which at least partially encloses a combustion chamber (56) filled with fuel, wherein the combustion chamber sleeve (60) is designed such that it changes its shape by pressure formed during combustion of the fuel so as to release a discharge orifice (112) leading out of the combustion chamber (56) into a further combustion chamber (44) of the inflator, for a combustion gas formed during combustion of the fuel.Type: GrantFiled: November 3, 2015Date of Patent: May 9, 2017Assignee: TRW Airbag Systems GmbHInventors: Sebastian Bierwirth, Achim Hofmann, Hans-Peter Neumayer, Dieter Spitzenberger, Hannes Nuiding, Thomas Schober, Josef Bommer, Tobias Breddermann, Dietmar Schwebel

Patent number: 9511738Abstract: An inflator for a protective device in a vehicle includes a diffuser (10) forming a substantially rotation-symmetric external housing of the inflator with a closing member (12), wherein the diffuser (10) includes a plurality of discharge orifices (78) arranged in a row, and which are of circular shape. The inflator also includes a filter (46) and a combustion chamber component at least partially enclosing at least one of a combustion chamber (56) and a combustion chamber sleeve (60), wherein the filter (46) extends in a ring-shaped manner about the combustion chamber (56) and, at a position of its ring-shaped extension, includes a critical filter portion (120) which is closer to the combustion chamber component than the remaining filter areas situated at its ring-shaped extension, wherein the critical filter portion (120) has a reduced thickness compared to areas of the filter that are adjacent to the critical filter portion (120).Type: GrantFiled: November 3, 2015Date of Patent: December 6, 2016Assignee: TRW Airbag Systems GmbHInventors: Sebastian Bierwirth, Achim Hofmann, Hans-Peter Neumayer, Dieter Spitzenberger, Hannes Nuiding, Thomas Schober, Josef Bommer, Tobias Breddermann, Dietmar Schwebel
