Abstract
Abstract An air bag curtain, particularly for a vehicle window, comprises several tube-shaped chambers which are arranged side-by-side. The chambers are spaced from one another and can be filled with gas and have a largely circular cross-section after being filled with gas. In the effective gas-filled position, the air bag curtain extends between two lateral fastening points. The chambers, which are crossed by a tension line connecting the two fastening points with one another, are constructed with a bulge in the crossing area which results in the oval cross-section being oriented approximately in the direction of the tension line.
