Abstract:
An inflatable restraint system with selectable ventilation, comprising:a base plate defining a vent aperture;an inflatable cushion secured to said base plate;an inflator for inflating said inflatable cushion with inflation gas;a vent plug secured to said base plate for substantially sealing said vent aperture and thereby inhibiting ventilation of the inflation gas from said inflatable cushion through said vent aperture;an initiator secured to said vent plug for rupturing said vent plug upon selective activation of said initiator and thereby allowing ventilation of the inflation gas; anda pyrotechnic material contained within said initiator that upon selective activation of said initiator supplies an explosion,whereby the force of the explosion of the pyrotechnic material pushes against the base plate and the vent plug thereby rupturing the vent plug.
