发明名称 Dispositivo de sombreamento para uma lâmpada de farol de veículo e processo de fabricacão de um dispositivo de sombreamento desse tipo
摘要 A screening device, in particular a low beam shield or screen, is disclosed for screening the luminescent body of a motor vehicle headlamp. The screening device (1) consists of a sheet metal part and has a welding lug (3) shaped at the edge of the screening surface (2, 4a, 4b) of the screening device (1). The welding lug (3) has a recess (5) whose shape is substantially determined by the shape of an area (4a) of the wall of the screening device (1) opposite the welding lug (3). These screening devices (1) are shaped and stamped in series out of a metal sheet. The distance between two successive screening devices (1) is smaller than the longest dimension of each screening device (1). This screening device (1) enables about 15 % material savings without impairing its operation.
