ABSTRACT:
An air bag has a pair of circular fabrics overlapping one upon the other with their marginal portions being stitched by crossing a sewing thread on the side of their edges to form a seam so that the seam is showing. The marginal end portions can be neatly enwrapped by the seam, not only providing the air bag with an unimpaired appearance but also making it compact when folded.
