Abstract
An air-bag (10) is disclosed which defines at least one inflatable region (14). The air-bag (10) is provided with a gas supply duct (22) which extends into the air-bag (10). The gas supply duct (22) is formed of fabric and is provided with at least one outlet aperture (24) therein through which gas may flow into the said at least one inflatable region (14) of the air-bag (10). The outlet aperture (24) is provided with a reinforcement to reinforce the periphery of the aperture (24) in order to prevent undesirable fraying of the fabric around the periphery of the aperture (24), or undesirable deformation characteristics of the fabric around the periphery of the aperture (24), as the air-bag (10) is inflated.
