Patent number: 11548470Abstract: An inflator for generating inflation gases for a safety device includes a housing having an internal cavity including a combustion chamber and a filter chamber. A filter is disposed in the filter chamber. A separating member is disposed in the housing on a first axial side of the filter and separates the filter chamber from the combustion chamber. An insulating member is disposed in the filter chamber on a second axial side of the filter. The second axial side is opposite the first axial side. The separating member is coupled to the insulating member.Type: GrantFiled: December 22, 2020Date of Patent: January 10, 2023Assignee: Autoliv ASP, Inc.Inventors: Romain Danielou, Matthew A. Cox, Kevin Smith, Ludovic Pogeant, Jean Champendal, Ludovic Cueff, Dominique Louboutin, Laurent Mazeas, Sebastien Delacroix, Gildas Clech

Patent number: 8720946Abstract: A gas generator has two pyrotechnic charges in two chambers having openings for gas outlet to the outside. Only the first chamber is provided with an igniter for first charge. The chambers are separated by a third wall with a through hole for permanent gas communication, sealed in an initial state by a cap. The cap is configured to be broken under the pressure of the combustion gases from first charge to keep the hole opened permanently and allow the combustion gases from the first charge to go via the hole kept permanently opened from a first chamber to a second chamber, where these gases induce the combustion of charge.Type: GrantFiled: April 15, 2011Date of Patent: May 13, 2014Assignee: Autoliv Development ABInventors: Gérald Prima, Sébastien Kermarrec, Maxime Lejeune, Gildas Clech
