To produce an inflatable belt (1), especially as a safety belt, a fabric is woven in two layers (O,U) and divided across its width into three equal zones. The warps of the two outer zones (LA,RA) are thinner than the warps for the center zone (M). To produce an inflatable belt (1), especially as a safety belt, a fabric is woven in two layers (O,U) and divided across its width into three equal zones. The warps of the two outer zones (LA,RA) are thinner than the warps for the center zone (M). Two narrow folded zones (FZ) are on both sides of the center, between it and the flanking outer zones, where the warps are thinner than those in the center but coarser than the warps in the outer zones. The two woven layers are bonded together at their outer edges, and also at the narrow folded zones. One outer zone is folded over on one surface of the center zone, along the folded zone, and the other outer zone is similarly folded on to the other surface of the center zone, to give a flattened Z-shape on the warp direction. The center zone is turned inside out so that the original outer surfaces face each other with the folded outer zones between them. The warps of the outer zones are of a thickness used for airbags, and are one-tenth the thickness of the warps in the center zone. The warps in the narrow folded zones have a thickness of about one-half of those in the center zone. The two woven layers are joined together by at least two shear yarns on the warp direction, at the middle of the center zone. Shear yarns are also woven or sewn at the narrow folded zones. The woven fabric is coated before folding. The wefts are monofilaments and/or multifilaments.
