PROBLEM TO BE SOLVED: To provide a hollow weave air bag capable of suppressing gas leakage from a cut face of the laminated hollow weave air bag and improving an inner pressure maintenance performance.SOLUTION: A hollow weave air bag is made by weaving at least two base clothes into an expandable bag-like shape. The hollow weave air bag comprises: a circumference junction which is located on a circumference of an expansion part; and an outer edge part which extends outward of the circumference junction. A twill-like structure region made of single weave structure is formed at least at a part of the circumference junction and/or the outer edge part. The twill-like structure region is composed so that when a continuous connection line is formed by tying a sinking structure point with another sinking structure point on the top, bottom, left or right of the sinking structure point in a minimum unit diagram of a weave structure diagram, the connection line can be diagonally extended on the weave structure diagram as a whole. The hollow weave air bag has a laminated outer surface.SELECTED DRAWING: Figure 3 |
