A dual stage inflator device including a housing defining first and second chamber each containing a quantity of gas generant material ignitable to produce combustion products. A divider plate, separating the first chamber from the second chamber, is disposed and fixed within the housing. The divider plate includes an opening to allow gas flow communication from the second chamber to the first chamber. A removable plug element is normally disposed in the divider plate opening to prevent gas flow communication between the first chamber and the second chamber when in a static state.
