Abstract
A dashboard is made that presents a cover for an air bag protection system, the cover being invisible from the outside and being defined by an inside line of weakness in the wall of the dashboard, the line of weakness defining an opening for the air bag. A layer of hard plastics material is injected molded; the line of weakness is cut locally inside the wall; the outside of the plastics layer is covered with a decorative covering; a tab with a hinge for hinging the cover is fastened to the cover; the reinforcing frame is fastened to the plastics layer, and prior to welding, it is ensured that a vibratory discontinuity exists between the frame and the tab so that during welding some of the vibration generated is absorbed away from the line of weakness; and the tab is fastened to the reinforcing frame.
