  "textContent": "A dual stage inflator (10) has a divider plate (40) that separates gas generant (20) in the primary chamber (22) from gas generant (20) in the secondary chamber (33). Burning of the gas generant (20) yields inflation gas for inflating a vehicle airbag. The gas generant (20) in the primary chamber (22) is ignited from a separate ignition train than the gas generant (20) in the secondary chamber (33). The divider plate (40) is capable of moving during the operation of the inflator. Before the inflator (10) is activated, the divider plate (40) rests against the inner surface of the lower housing (54). The divider plate (40) prevents inflation gas from the primary chamber (22) from igniting the gas generant (20) in the secondary chamber (33). When the internal pressure of the secondary chamber (33) exceeds the internal pressure of the primary chamber (22), the divider plate (40) is displaced in an upward direction thereby permitting inflation gas from the secondary chamber (33) to flow around the divider plate (40) and out of the inflator.",
