  • Patent number: 6929313
    Abstract: A plastic fender has an upper first edge area and a second edge area extending at an approximately 90° angle thereto. The fender is fixed to the vehicle body in the second edge area by a screw. Furthermore, along the first and second edge areas, a plurality of spaced-apart elongated holes is provided, which admit a mounting section of a guide element which in turn is mounted to the vehicle body with a mounting screw. On the mounting sections of the guide elements, a guide edge covering, respectively, the opposite longitudinal edges of an elongated hole is provided such that, during thermal expansion, the fender can elongate unhindered. For this purpose, the longitudinal extent of the mounting section of the guide elements is shorter than the corresponding longitudinal extent of the elongated hole.

  • Patent number: 4561042
    Abstract: An instrument illuminating arrangement for the glare-free illumination of indicators such as characters of the instrument display area or, especially of movable hands or movable displays or electronically variable characters, has an excitation source which is so arranged as to irradiate the surfaces of the indicators and cause them to emit visible light. Preferably the excitation source generates light energy at least to some extent in the invisible range and the indicators' surfaces are provided with luminophors which convert the invisible light into visible light so that the light energy supplied to the indicators will not disturb the operator of, for example, a vehicle equipped with such instruments.
