Abstract
An airbag includes a circumferential plane, a margin, a receiving plane and a second seam line. The circumferential plane is formed by being seamed to form a first seam line from its base end to its farthest end and has a closed cross section. The margin for the first seam line is provided on the circumferential plane. The receiving plane extends integrally from the circumferential panel and receives a passenger at an impact. The circumferential plane and the receiving plane are seamed together to form the second seam line. The second seam line crosses the first seam line and goes across the margin in a width direction of the margin. According to the airbag, its manufacturing efficiency can be improved.
