An air-bag is formed using two substantially identical, but inverted, fabric elements. Each element defines a generally rectangular region having, at one narrow end thereof, a generally triangular extension, one side of which is co-extensive with one side of the rectangular region. The other side of the rectangular region has a triangular or thumb-like projection. The two elements are substantially superimposed with the rectangular regions thereof aligned. If the ends of the rectangular regions carrying the triangular extensions are separated, the projections or thumbs may be folded to form side-walls, and the triangular projections may be folded inwardly to form an end region. A single peripheral seam may seal the two elements together to form an air-bag. |
