ースとで構成されている。2. Description of the Related Art An airbag device is a safety device that protects an occupant by inflating the airbag in the event of a vehicle collision.
Generally, it is composed of an inflator which is a gas generator, an airbag which is inflated by the gas of the inflator, and an airbag case which encloses the inflator together with the airbag in a substantially airtight manner.

ガス抜き穴としてベントホールが形成されている。When the airbag device is operated,
The gas ejected from the inflator fills the inside of the airbag to generate an internal pressure, and the internal pressure causes the airbag to be instantly expanded and inflated. And, in the airbag,
A vent hole is formed as a vent hole.

いうものである。By the way, the airbag having the vent hole has a problem that the gas of the inflator is discharged from the vent hole when inflated. As a means for solving this problem, for example, there is an airbag disclosed in Japanese Utility Model Laid-Open No. 132532/1990. In this airbag,
The vent hole is closed with a special film so that the inflator gas is not discharged to the outside of the airbag until the inside pressure of the airbag reaches a predetermined internal pressure, so the amount of inflator gas generated can be reduced by that amount and cost reduction can be achieved. That is.

る。As described above, in the vehicle airbag of the present invention, a required portion of the remaining sewing margin is extended to the vent hole, and the remaining extension portion is covered with the vent hole. It is sewn to the fabric of the airbag body, and the remaining margin extending portion opens the vent hole by a predetermined deployment pressure of the airbag, and the remaining margin of sewing is used as a member for covering the vent hole. The material cost does not change much since it is extended and used. Moreover, since the remaining margin extension part is continuous with the original remaining margin, the sewing part can be sewn only by sewing the tip end side of this extension part. It has a remarkable effect that processing can be performed extremely easily.
