Abstract:
A passenger's seat airbag device comprising: an airbag folded up and housed in a case for being extended/inflated and protruded backward of a vehicle while pushing and opening a door arranged in an instrument panel, by introducing an inflating gas thereinto from a gas inlet port,wherein said airbag comprises, as a shape when completely extended/inflated: a passenger's side wall portion arranged on the passenger's side and generally in a vertical direction; and a peripheral wall portion converging generally into a conical shape from the outer peripheral edge of said passenger's side wall portion forward of the vehicle, wherein said gas inlet port is arranged as an open face on a forward portion on the lower side of said peripheral wall portion when said airbag is completely extended/inflated, wherein said gas inlet port is mounted at its peripheral edge on said case, wherein said airbag is preliminarily folded to make the conical shape associated with the peripheral wall portion flat, and then vertically and horizontally folded, wherein in the preliminary folded shape of said airbag, a portion near the upper edge of said passenger's side wall portion is arranged at a position to confront said gas inlet port, and said passenger's side wall portion is expanded flatly on a part of said peripheral wall portion that becomes a lower side when the airbag is deployed; wherein when said airbag is preliminarily folded, said peripheral wall portion is folded up such that substantially all the area of said passenger's side wall portion is expanded flatly; wherein in the preliminarily folded shape of said airbag, the portions of said peripheral wall portion on the left and right sides of said gas inlet port are so folded to form valley creases in the longitudinal direction that the intermediate portion of the flatly extended passenger's side wall portion to the left and right edges is brought close to said gas inlet port and arranged at the peripheral edge of said gas inlet port on the side of said passenger's side wall portion, and wherein the portion of said peripheral wall portion near the joint to the upper edge of said passenger's side wall portion is folded to form valley creases in the transverse direction.
