Provided is an air-bag integrally formed by hollow weaving and including a control seam for restricting expansion. The control seam is extended from the base fabric on one surface of an expansion portion of the air-bag to the base fabric on another surface, and the base fabrics are joined. The control seam extending from the base fabric on the one surface to the base fabric on the other surface, and the control seam extending symmetrically from the base fabric on the other surface to the base fabric on the one surface constitute a pair of control seams One or more pairs of the restriction yarns are arranged in a block shape, forming a restriction yarn block. Adjacent restriction yarn blocks are disposed in a parallelly staggered manner with respect to the direction in which the restriction yarns extend. |
