  • Patent number: 11548470
    Abstract: 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: Grant

  • Patent number: 11485313
    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.

  • Patent number: 11479205
    Abstract: A dual stage inflator a dual stage inflator for an inflatable vehicle safety device includes a housing defining a first chamber containing a first gas generant material. An ignitor cup is disposed in the first chamber and defines an interior containing an ignitor material. A first ignitor device extends into the interior of the ignitor cup. A combustion cup and a lid are disposed in the first chamber and cooperate to define a second chamber containing a second gas generant material. The combustion cup includes a cup sidewall extending between a first axial end and a second axial end. The first axial end is an open end. The lid is normally in a closed position relative to the combustion cup to close the open end of the combustion cup and is moveable away from the combustion cup in response to an increase of pressure within the combustion cup for venting combustion gas out of the combustion cup. A second ignitor device extends into the combustion cup and closes the second axial end of the combustion cup.

  • Patent number: 11273787
    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.
