A one-piece woven air-bag in the form of an inflatable curtain has two inflatable regions separated by an uninflatable region which incorporates an expansion panel to relieve excessive tension that may arise within the inflatable curtain. The expansion panel comprises a region where there are two outer layers of fabric interconnected by an intermediate or third layer extending from the first layer to the second layer. Slit lines are provided in the outer layers so that the expansion panel may expand when subjected to tension.
