Abstract: A dual stage inflator includes a housing defining an internal cavity including a combustion chamber. The combustion chamber includes a first portion having a first gas generant material separated from a second portion having a second gas generant material. A gas generant retaining wall is disposed in the housing. A first stage ignition device is disposed in the first portion of the combustion chamber. A second stage ignition device is disposed in the second portion of the combustion chamber. A lid normally closes the second portion of the combustion chamber and is spaced from the gas generant retaining wall. The lid is moveable to an open position opening the second portion of the internal cavity to release combustion gas and abutting the gas generant retaining wall in response to an increase of pressure within the second portion of the combustion chamber. An outer side of the lid and the adjacent side of the gas generant retaining wall are cooperatively configured to allow a flow of combustion gas between the gas generant retaining wall and the lid when the lid abuts the gas generant retaining wall in the open position.

Abstract: Pressed and segmented gas generant grain assemblies formed from a plurality of symmetric gas generant pieces or segments are disclosed. The symmetric pieces or segments are arranged circumferentially to define a substantially round, segmented body. In certain variations, the symmetric segments are substantially free of polymeric binder and have a high density. The segmented pressed grain assemblies are more robust and less expensive to manufacture, while still exhibiting desired combustion performance. Methods of making such segmented gas generant grain assemblies are also provided.

Abstract: An inflator for generating inflation gases for a safety device includes a filter having a main body portion constructed of metal and an opening passing through the main body portion in an axial direction. The opening has a first end with a first diameter at a first axial side of the main body portion and a second end with a greater, second diameter at a second axial side of the main body portion. A plate disposed in the housing axially separates a filter chamber containing the filter and a combustion chamber containing at least one gas generant material. The plate includes a weakened zone which opens in response to an increase in pressure within the combustion chamber with a plurality of petals axially extending into the filter chamber. A first axially extending portion of the filter is adjacent the plate and opposes radial movement of the plurality of petals upon opening of the weakened zone into the filter chamber.

Abstract: An airbag assembly may include an airbag and an inflator in fluid communication with the airbag. The inflator may have a first chamber containing a first gas source and a second chamber containing a second gas source. A filter module may be positioned to filter and redirect gas flows from the first and second gas sources. The filter module may be constructed by securing a baffle within an interior cavity of a filter medium having a generally tubular shape, prior to installation of the filter module the inflator. The baffle may be supported directly by the material of the filter module, by a bracket, or by a support structure formed of wire thicker than that of the filter medium. The baffle may maintain isolation between the first and second chambers, or may help gas from the first gas source initiate gas provision from the second gas source.
