Patent attributes
An airbag apparatus for a front passenger seat includes an airbag inflatable into a generally square conical contour whose top is deployable at the front end. The airbag is mounted on a case together with an inflator by the periphery of a gas inlet port which is located proximate the front end of the airbag. The airbag includes in a passenger side wall a recessed area that is sunken forward and extends vertically generally at airbag inflation. A seam that joints peripheral edges of a base material of the circumferential wall together extends forward from the recessed area. The seam is slanted off a front and rear direction such that the front end of the seam is directed toward either left or right when the airbag at full inflation is viewed from an up and down direction.
