That is, this airbag has an outer shape formed by superimposing two circular cloths, an inflator-side cloth and an occupant-side cloth, and stitching the outer peripheral edges of these cloths. An opening into which the head of the inflator is inserted is formed substantially at the center.

る。In the airbag, an inner cloth having substantially the same diameter as these two cloths is provided between the inflator side cloth and the occupant side cloth, and the inner peripheral edge portion of the inner cloth serves as the inflator side cloth. It is sewn together with the passenger side cloth. Notches are intermittently formed in the outer peripheral edge of the inner cloth, and the inner cloth is sewn to the inflator-side cloth at a position which is circumferentially separated from the notch at an intermediate position in the radial direction. Has been done.

まうというデメリットも有している。However, in the above-mentioned conventional airbag, the inner cloth is large, and the notch is provided on the inner cloth, so that the shape is complicated, and the sewing portion is located at the outer peripheral edge portion and the intermediate position of the inner cloth. Must be set for each, and there is a disadvantage in terms of cost and man-hours. Further, in the above-mentioned conventional airbag, since the vent hole is formed in the inflator-side base cloth within the attachment range of the inner cloth, the gas of the inflator hitting the inner cloth is changed during the inflation of the airbag. It also has the disadvantage of being released from the vent holes.

能である。That is, the feature of the airbag of the present invention which meets the above object is that the outer shape of the airbag is formed by sewing the outer peripheral edge portions of the inflator side cloth and the passenger side cloth. In an airbag for a vehicle in which an inflator side cloth is formed with an opening into which the head of the inflator is inserted, an inner cloth is attached to the inner surface of the airbag to cover the opening, and the gas flow of the inflator is changed. The inner cloth is formed to be smaller than the inflator-side cloth in a required size, and the outer peripheral edge portion of the inner cloth is partially sewn to the inflator-side cloth, and a vent hole is provided outside the attachment area of the inner cloth of the airbag. Is formed. In this case, the vent hole can be formed on the outer peripheral side of the sewn portion between the inner cloth and the inflator side cloth.
