Inflatable restraint system with selectable ventilation

An inflatable restraint system with selectable ventilation, comprising:

• a base plate defining a first vent aperture and a second 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 apertures and thereby inhibiting ventilation of the inflation gas from said inflatable cushion through said vent apertures;
• and
• 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;
• wherein said initiator creates an explosive force towards said base plate between said vent apertures upon selective activation of said initiator.
