  • the invention relates to a system for observing things which are located above or to the side of the vehicle, according to the preamble of claim 1.
  • the traffic-regulating devices e.g. traffic signs and traffic lights
  • the traffic-regulating devices are often located above or to the side of the vehicle, outside the driver's natural, direct field of vision. The latter must therefore move from his sitting position to observe them.
  • GB 1 177752 and WO 86-05749 there are known modifications of vehicle rear-view mirrors which allow them to be rotated by suitable means (cables or electric motors) in order to look in front of the vehicle.
  • These devices are mechanically complex, in particular if the view of objects located in front of the vehicle is also to be made possible.
  • a device known from US Pat. No. 5,316,360 provides for integrating a small window in the sun visor through which objects located above the vehicle can be observed.
  • US Pat. No. 5,214,540 proposes an optical system consisting of a combination of a plurality of curved mirrors, which, by means of a suitable combination and arrangement, reflects objects positioned in any manner into the field of view of an observer.

  • a further advantageous embodiment of the invention is the integration of a prism or a lens firmly in the windshield, in the sunroof or in or on the sun visor of the vehicle. When looking in the direction of this prism, the vehicle operator can see objects that are above or are located in front of the vehicle. When looking into a concave lens, he sees vehicles above and to the side.

Abstract

L'invention concerne un système pour augmenter le champ de vision de conducteurs de véhicules à l'aide d'un élément optique, situé à l'intérieur du véhicule concerné. A cette fin, un élément optique est placé dans le champ de vision du conducteur, de manière que ce dernier puisse voir des objets qui ne se trouvent pas dans son champ visuel naturel direct et se situent à l'avant au-dessus du véhicule ou à côté dudit véhicule, sans avoir à sortir de sa position assise. A cet effet, il est prévu un miroir, un prisme ou une lentille de structure Fresnel, monté(e) au bon endroit, par exemple sur le pare-brise ou sur le tableau de bord. Afin d'améliorer l'aptitude à la circulation routière, l'élément optique se présente de manière à réduire la réflexion et la distorsion et agit à l'encontre d'éventuels effets d'éblouissement.
