PURPOSE:To improve the quality and permit the simple manufacture by forming a plurality of double hollow woven parts for fluid introducing bag part inside each fastening single structure band region and forming a fastened single structure ear part through the double hollow woven structure region arranged on the peripheral edge of the single structure band region. CONSTITUTION:A hollow woven fabric 1 for air bag is formed by arranging, for example, three pieces of unit air bag fabric 2, keeping the prescribed intervals. In each unit air bag fabric 2, a double hollow woven part 3 for fluid introducing bag part is arranged at the center, and a ring-shaped fastened single structure band region 4 is arranged so as to surround the double hollow woven part 3. Further, on the periphery of each unit air bag fabric 2, a double hollow woven structure region 5 is arranged. Further, each ear part 6a, 6b on the both sides is formed from the fastened single structure. Therefore, the hollow woven fabric having a prescribed density can be obtained in simple manners at a low cost without using a special weaving machine. |
