Abstract (en)
[origin: WO9515286A1] Into two films (1, 2) having predetermined width and length, a self-sealing air-blowing tube (10) is inserted in the lengthwise direction of the films, and both side edges of the films are formed as sealing edges (3, 4). The two films are sealed laterally along the widths of the films with a plurality of lateral parting lines (5, 6) so as to connect together a plurality of individually partitioned expanded portions (7), on each of which one or more bending seals (8-1, 8-2, ...) extending between widely spaced adjacent parting lines (5, 6) are formed so as to divide each expanded portion into two or more divisional expanded portions (7-1, 7-2, 7-3, ...). This air bag bendable after expanded is thus formed in such a manner that, after it has been expanded by blowing air thereinto, the expanded portions can be bent easily and freely at the bending seals, and in such a manner that the air bag thus bent can be formed to an annular cross-sectionally polygonal shape by connecting the opposed end portions of the air bag to each other.
