<p>A dual stage airbag inflator (30) has primary and secondary combustion chambers (1, 2) and a common gas exiting port (7) for controlling the combustion pressure in both combustion chambers. This inflator can inflate an airbag at different rates dependent on the firing sequence used. The low output performance level occurs when only the primary stage is deployed. Simultaneous firing of both the primary and secondary stages constitutes the upper performance limits, while staging results from deployment of the primary stage and some time later deployment of the secondary stage. The staging provides a means to supply inflation gas in a variable rate fashion.</p> |
