摘要：A method for producing for deployment in an air bag module an air bag which in its inflated condition has a three-dimensional form via the fabrication of a two layered material web from which individual air bag cut-outs are continuously cut includes connecting the material web layers to one another along closed contours such that the edges so formed from the connection of the material web layers to one another exhibit a trapezoidal-like shape. The method also includes cutting along a cutting line such that the path of the cutting line of the individual air bag cut-out to be cut out does not correspond, in the area of the corners of the longer trapezoid side, to the contour edge but, instead, to contribute to the formation of the height of the three-dimensional air bag,extends inwardly.
