An air-bag is formed from two super-imposed layers of fabric which define between them at least one inflatable region. A gas supply duct extends into the air-bag. Apertures are formed in the gas supply duct. The gas supply duct is of elongate form, and is formed from a fabric having intersecting warp and weft yarns, the warp and weft yarns being inclined at an angle of between 30° and 60° and (preferably 45°) to the axis of the gas supply duct.
