Optische Rückfahrhilfe für KraftfahrzeugeOptical reversing aid for motor vehicles
Beim Rückwärtsfahren ist es für den Führer eines Kraftfahrzeugs ausserordentlich wichtig die Lage hinter dem Heck seines Fahrzeugs zu erkennen.Je nach Bauart des Fahrzeugs liegt die Sichtlinie durch das Rückfenster mehr oder weniger viel zu hoch um kleine Kinder und niedrige Hindernisse zu sehen oder den Abstand zum nächsten Auto in der Pa-rkreihe richtig einzuschätzen.When reversing, the position behind the rear of his vehicle is extremely important for the driver of a motor vehicle Depending on the type of vehicle, the line of sight through the rear window is more or less too high to see small children and low obstacles or to correctly estimate the distance to the next car in the park row.
Um diesem Übelstand abzuhelfen wurden Spiegelkombinationen vorgeschlagen, welche sich aber als unpraktisch erwiesen haben. Auch Verkleinerungslinsen auf der Rückscheibe des Autos,welche das Blickfeld erweitern sollten,haben sich nicht bewährt.To remedy this problem, combinations of mirrors have been proposed, but which have proven impractical. Also reducing lenses on the rear window of the car, which should broaden the field of vision have not proven their worth.
"Die vorliegende Erfindung befasst sich damit, diesen Raum hinter dem Fahrzeug in die Sicht des Führers besser eizubeziehen. Es kommt das Prinzip der Lichtbrechung durch Prismen zur Anwendung."The present invention is concerned with putting that space behind better include the vehicle in the driver's view. The principle of light refraction by prisms is used.
Um ein nicht zu kleines Blickfeld zu erhalten,muss das in der Nähe des Hecks angebrachte Prisma ziemlich gross sein.Es erscheint aber nicht praktikabel ein grosses schweres Glasprisma zu verwenden. In order to have a field of view that is not too small, the prism attached near the stern must be quite large, but it does not seem practical to use a large, heavy glass prism.
Es wird deshalb vorgeschlagen eine Prismen-Rasterplatte aus Glas oder glasklarem Kunststoff,welche nur ein geringes Gewicht hat, in der Nähe oder auf der Rückscheibe des Fahrzeugs anzubringen. "Die Prismen-Rasterplatte soll nur einen Teil der Rückscheibe bedecken,so dass die normale Sicht nach hinten nicht wesentlich eingeschränkt wird.It is therefore proposed a prism grid plate made of glass or clear plastic, which is only light in weight, to be placed near or on the rear window of the vehicle. "The prism grid plate should only be part of the rear pane cover so that normal rearward visibility is not significantly impaired.
Die Prismen-Rasterung verläuft wagrecht und soll so fein sein, dass die Rasterung im Bild nicht stört.Das durch die Prismen-Rasterplatte sichtbare Bild ist seitenrichtig und in natürlicherThe prism grid runs horizontally and should be so fine that that the grid does not interfere with the image, thanks to the prism grid plate visible image is correct reading and in more natural
