Abstract
An air-bag comprising: a circumferential wall including facing wall portions which define a free inflation portion in which a distance between the facing wall portions is not controlled and a distance controlled portion in which a distance between the facing wall portions is controlled; and a tether including two edges on each of which a seam margin is provided, both seam margins has a linear stitch which joins the seam margin with the corresponding facing wall portion and controls a distance between the facing wall portions of the distance controlled portion, and at least one of the seam margins has a curved stitch which is continued from an end of the liner stitch and provided at least at one end of the seam margin. The curved stitch forms a gradually expanding portion between the free inflation portion and the distance controlled portion, which gradually expands in an outward direction perpendicular to the facing wall portions.
