Abstract
An air-bag in the form of an inflatable curtain has a plurality of zones each provided with vertically extending cells defined by seams. Uninflatable regions are provided, the uninflatable regions being provided with oval apertures. On deployment of the inflatable curtain, the oval apertures will distend to become circular, enabling the uninflated region effectively to stretch to moderate the tension generated between two anchoring points connected by straps to the lower edge of the air-bag.
