Patent number: 7338074Abstract: A gas generator includes a housing having an inner wall delimiting an igniter chamber peripherally, and at least one igniter opening into the igniter chamber. The gas generator further includes a cap arranged for displacement along the inner wall and delimiting the igniter chambe, said cap having a cylindrical peripheral wall and a radially extending cover wall. The peripheral wall has a first section extending from the cover wall in displacement direction (R) and a second section extending in a direction opposite thereto. The first and second sections lie against the inner wall and guide the cap during a displacement thereof. The cover wall is turned axially into the interior of the cap.Type: GrantFiled: December 15, 2003Date of Patent: March 4, 2008Assignee: TRW Airbag Systems GmbHInventors: Georg Schönhuber, Reed Inman

Patent number: 6626115Abstract: The invention relates to a gas generator comprising at least two combustion chambers filled with propellant charges and delimited by combustion chamber walls. The combustion chamber walls have outflow openings which in a non-activated state are closed by at least one applied membrane having an edge. One of an additional fastening device and a protective device is provided at least sections of the edge of the membrane. The device prevents a coming-off of the membrane from the combustion chamber wall.Type: GrantFiled: February 9, 2001Date of Patent: September 30, 2003Assignee: TRW Airbag Systems GmbH & Co.

Patent number: 6547278Abstract: A gas generator for a vehicle occupant restraint system has a combustion chamber delimited by a combustion chamber wall and filled with propellant granules. A structure is arranged in the combustion chamber for holding down the propellant granule, which has a disc-shaped holding face with grid holes, wherein the holding face is pressed into the combustion chamber and is connected in a form- and force-fitting manner with the combustion chamber wall. The structure for holding down the propellant granules is prestressed and presses elastically onto the propellant granules thereby arresting the propellant granules at a preselected filling level and at a variable distance from the combustion chamber cover.Type: GrantFiled: April 13, 2001Date of Patent: April 15, 2003Assignee: TRW Airbag Systems GmbH & Co. KGInventors: Karl Unterforsthuber, Karl-Heinz Sommer, Ingrid Hofbauer, Georg Schönhuber
