Abstract
A method of inflating an airbag with a fluid includes sending a signal to open a first valve and opening the first valve. The method also includes directing a control pressure through the first valve and toward a second valve. The method further includes throttling the second valve in response to the control pressure. The throttling of the second valve produces a variable inflation mass flow rate of the fluid at a second valve outlet. Opening the first valve and closing the first valve are performed as a step function to achieve a desired predetermined variable inflation mass flow rate of the airbag.
