Abstract: A particulate impingement device is carried by the air bag and has an impingement surface overlying the vent hole at a spaced relationship away from the vent hole so that the inflation gas exiting the air bag through the vent hole impinges on the impingement surface to deposit particulate by-products within the inflation gas upon the impingement surface.

Abstract: A supplemental inflatable restraint system including a compressed gas storage unit containing a compressed gas at a pressure and a two-state pressure switch attached to the compressed gas storage unit and responsive to the pressure of the compressed gas, the two-state pressure switch having a closed state in which current flows through the switch when the pressure of the compressed gas is above a threshold and an open state in which current does not flow through the switch when the pressure of the compressed gas is below the threshold includes a control circuit wherein a diode is connected in parallel with the pressure switch to form a parallel circuit with the pressure switch, an initiator is coupled in series with the parallel circuit of the diode and the pressure switch, a first electric line is connected to a first end of the series circuit and a second electric line is connected to a second end of the series circuit, wherein the series circuit has a first impedance when the pressure switch is closed, ind
