Abstract
An air bag device designed to protect passengers in a vehicle. In the device, an inflatable gas bag is inflated by a gush of high pressure gas which is discharged from a gas supply source through a gas discharging pipe and guided by a housing. The housing has defined therein large openings to introduce ambient air, and has mounted, at the region where the inflatable gas bag are mounted, gas permeable supporting plates and valve members urged against the gas-permeable supporting plates. The gush of the high pressure gas discharged through the gas discharging pipe sucks in and mixes with the ambient air introduced through the large openings in the housing. The resultant air-high pressure gas mixture passes through the supporting plates, opens the valve members and then, flows into the inflatable bag to inflate the latter.
