摘要： 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.

摘要： 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.

摘要： 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.
