Description of the Related Art As an airbag device to be installed in a passenger seat of an automobile, an airbag having a substantially quadrangular pyramid shape and a rectangular air inlet having a long rectangular shape at the top thereof and a horizontally long cylindrical shape. It is composed of an inflator and an airbag case, and the inflator is installed in the back of the airbag case, and the airbag is folded and stored on the inlet side, and the blow-in port is formed on the inner wall of the opening of the airbag case. It is known to be fixed. Part of FIG. 2 shows an example of the above-mentioned airbag. In this airbag 1, a belt-shaped body cloth 4 in which the width of the central portion in the longitudinal direction is formed wider than both ends is bent into a U shape, and Side cloth 5 having a substantially triangular shape is sewn on the left and right side edges to be formed into a substantially quadrangular pyramid shape.
Two bag-shaped attachment cloths 9 are attached, and a vent hole H is opened in the side cloth 5.

バッグを車体前後方向に交互に折り畳む方法がある。On the other hand, a conventional airbag folding method is disclosed in, for example, Japanese Unexamined Patent Publication No. 4-191141, in which both side portions of the airbag in the vehicle width direction are bellows-shaped with the airbag stretched forward. After folding in, there is a method of alternately folding the airbag in the front-back direction of the vehicle body.

に比べ下部が大きいものが提案されている。このエアバ
ッグの展開挙動には各種のものが試行されているが、そ
の中でもエアバッグの上部を先に展開させ、ついで下部
を展開させる挙動が一般的に良好であるとされている。By the way, in recent years, there has been proposed an air bag having a shape that greatly extends around the occupant's abdomen, that is, a shape in which the lower portion is larger than the upper portion. Various attempts have been made to deploy the airbag, but among them, the behavior of deploying the upper part of the airbag first and then deploying the lower part is generally good.

形状に膨張しない等の不都合が生じる。However, in the above-mentioned conventional folding method, since the upper and lower parts of the airbag are folded in the same manner, the upper part and the lower part of the airbag start to deploy at the same time,
As a result, before the inflation of the airbag is completed, the bag 1'protrudes temporarily toward the occupant as shown in FIG. 6 and does not immediately inflate into a predetermined shape unless a deployment shape regulation means such as a strap is provided. Inconvenience occurs.

である。As described above, according to the airbag apparatus for a passenger seat of the present invention, the airbag is folded into a strip-shaped body having a width substantially equal to the width of the gas inlet, and the strip-shaped body is provided on the lower side of the airbag. While the roll is wound in a roll shape, the upper part of the airbag in the form of a belt is folded into a bellows shape, and the airbag is stored in the airbag case.The upper part of the airbag folded in a bellows shape is inflated first. Then, by making the lower part of the inflating airbag upper part to be pulled out sequentially, and by gradually expanding the airbag,
This has the remarkable effect of reducing the temporary protrusion of the airbag before inflation and achieving stable inflation of the airbag.
