Abstract
An image-reproducing arrangement for motor vehicles, in which a real image is represented as virtual image in the field of vision of the vehicle user by means of a lens and the windshield following the lens in the path of the light rays; the real image and the lens are thereby arranged at the upper edge of the windshield. Only a mirror element is located between the lens and the windshield within the area of the surface of the instrument panel. This mirror element requires a relatively small amount of space and by reason of the relatively large distance from the lens element offers the possibility to match the virtual image falling into the eye of the vehicle user to the respective prevailing conditions.
