Patent number: 8215669Abstract: An airbag has a skin enclosing a gas chamber and the skin has a vent which is closed in the resting state of the airbag and which opens when the pressure in the gas chamber exceeds a pre-determined value is described. The vent includes a vent hole in the skin and a tearable connection closing the vent hole in the resting state of the airbag. The airbag is folded to a package at least along a first direction and the tearable connection connects the skin around the vent hole directly to itself such that the tearable connection extends from a first point to a second point. In order to ensure that the vent remains closed during deployment and that the vent opens after the pressure inside the gas chamber exceeds a predetermined value within a rather small tolerance of the pressure, the line connecting the two points encloses an angle between 30° and 60° with the first direction.Type: GrantFiled: April 3, 2009Date of Patent: July 10, 2012Assignee: Autoliv Development ABInventor: Alan Bradburn

Patent number: 8201847Abstract: A safety arrangement includes an airbag housing, a cover and pair of horn contacts for actuating a vehicle horn. The airbag housing mounts to a steering wheel frame. The cover is resiliently mounted on the housing and spaced therefrom such that the cover may be depressed towards the housing to close the horn contacts. The housing and cover are hooked to one another for preventing subsequent disconnection of the cover from the housing upon release of the cover to open the horn contacts. A stop is mounted to one of the cover and the housing for movement between a operable position, in which the stop arrests relative movement of the cover and housing towards one another so as to prevent un-hooking of the cover from the housing, and an assembly position, in which the cover may be depressed sufficiently far towards the housing to allow un-hooking of the cover from the housing and consequent disconnection of the housing and cover upon release of the cover.Type: GrantFiled: June 15, 2006Date of Patent: June 19, 2012Assignee: Autoliv Development ABInventors: Thierry Hondier, Rémi Baillivet, Fréderic Langlois, Samuel Vanzieleghem, Jérome Bertrand
