Abstract
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.

An air-bag in the form of a woven inflatable curtain, the inflatable curtain comprising at least two spaced-apart inflatable regions and an uninflatable region, the uninflatable region incorporating an expansion panel, the expansion panel having first and second outer fabric layers, the outer fabric layers being interconnected by an intermediate fabric layer extending from a first region where it merges with the first outer fabric layer to a second region where it merges with the second outer fabric layer, there being a first slit line formed in the first outer fabric layer between the first region and a first adjacent edge of the expansion panel, and there being a second slit line formed in the second outer fabric layer between the second region and a second adjacent edge of the expansion panel.
