Vorrichtung zum Blendschutz vor Kraftfahrzeugen»Device for glare protection in front of motor vehicles »

Die Auslöschung des in allen Eichtungen schwingenden Lichts durch Polarisatoren, welche das Licht nur in einer einzigen Schwingungsrichtung hindurchtreten lassen, ist bekannt. Durch Hintereinanderschalten zweier Polarisationsscheiben, als Polarisator und Analysator bezeichnet, und Drehen dieser Scheiben gegeneinander kann, wenn die Schwingungsrichtungen beider Scheiben einen Winkel von 9o° bilden, also senkrecht aufeinanderstehen, das Licht vollkommen ausgelöscht werden- Es wurde bereits vorgeschlagen, Kraftfahrzeuge mit polarisierten Scheinwerfern auszustatten und im Gesichtsfeld des Fahrers einen als Schutzblende wirkenden Analysator, der auch in Form einer Polarisationsbrille ausgebildet sein kann, anzubringen.The extinction of the light oscillating in all directions through Polarizers which allow light to pass through only in a single direction of oscillation are known. By cascading two polarizing disks, known as polarizer and analyzer, and rotating these disks against each other when the directions of oscillation both discs form an angle of 90 °, i.e. stand perpendicular to each other, the light will be completely extinguished - it has already been suggested Equip motor vehicles with polarized headlights and in the driver's field of vision an analyzer acting as a protective screen, which is also in the form a polarization glasses can be designed to be attached.

Dieses Verfahren, welches die Blendung durch entgegenkommende Fahrzeuge beheben sol hat den Nachteil, dass die Lichtstärke der eigenen Scheinwerfer durch die Polarisation stark herabgesetzt wird, so dass keine ausreichende Fahrbahnbeleuchtung mehr vorhanden ist. Ausserdem ist ein Blendschutz gegenüber entgegenkommenden Fahrzeugen nur dann gegeben, wenn auch diese mit polarisierten Scheinwerfern ausgestattet wind. Aus diesen Gründen konnte sich kein Polarisationsverfahren zum Blendschutz vor entgegenkommenden Fahrzeugen einführen.This procedure, which aims to eliminate the glare from oncoming vehicles has the disadvantage that the light intensity of its own headlights is greatly reduced by the polarization, so that there is insufficient lane lighting there is more. In addition, glare protection against oncoming vehicles is only provided if these are also polarized Headlights fitted wind. For these reasons, no Polarization process for glare protection from oncoming vehicles introduce.

Bekanntlich tritt Blendung nicht allein durch entgegenkommende, sondern auch durch nachfolgende Fahrzeuge auf, dadurch, dass deren Scheinwerferlicht am Innenspiegel reflektiert wird. Der Aussenspiegel ist meist derart eingestellt, dass nicht das volle Scheinwerferlicht des nachfolgenden Fahrzeuges zur Wirkung kommt.As is well known, glare occurs not only through oncoming people, but also by following vehicles, in that their headlights are on Inside mirror is reflected. The outside mirror is usually set in such a way that the full headlights of the following vehicle are not shown Effect comes.

Nachdem durchsichtige polarisierende Folien z.B. aus Kunststoff, bekannt sind, wird eine Vorrichtun g vorgeschlagen, welche die Blendung durch den Wageninnenspiegel vollkommen beseitigt. Dazu wird ein Teil oder die gesamte Fläche der Wagenrückscheibe mit einer Polarisationsfolie beklebt. Das durch das Rückfenster eintretende Licht ist in seiner Lichtstärke bereits geschwächt und schwingt nur in einer Hichtun g. Um die erfindungsgemässe Blen-dschutzäinrichtung zur Wirkung zu bringen, muss auch der Innenspiegel, der vorzugsweise rund ausgebildet ist, mit einer durchsichtigen Polarisationsfolie beklebt wer den. Durch Drehen des Spiegels werden die Schwingungsrichtungen gekreuzt.Since transparent polarizing foils, e.g. made of plastic, are known, a Vorrichtun g is proposed, which the glare from the car interior mirror completely eliminated. For this purpose, a part or the entire area of the rear window of the car is covered with a polarization film. That through the Light entering the rear window is already weakened in its light intensity and only oscillates in one direction. To the blind protection device according to the invention To bring it into effect, the inside mirror, which is preferably round, has to be covered with a transparent polarization film the. By turning the mirror, the directions of oscillation are crossed.

es lässt sich jede gewünschte Lichtabschwächung erzielen» Ein vollständiges t Kreuzen der Schwingungsrichtungen wäre unzweckmässig, weil in diesem Falle das folgende Fahrzeug im Rückspiegel vollkommen unsichtbar wäre. Selbstverständ-J lieh kann durch diese Anordnun g auch das Tageslicht geschwächt oder ausgelöscht werden. Bs ist daher zweckmässig, die Schwingungsrichtungen der Folien am Tage parallel einzustellen, so dass im Rückblick eine ausreichende Helligkeit vorhanden ist. Das beschriebene Verfahren kommt also zur Wirkung, ohne dass das folgende Fahrzeug mit polarisierten Scheinwerfern ausgerüstet ist und bietet besonders guten Schutz vor Verkehrsteilnehmern, die sich item eigenen Fahrzeug zu nahe mit eingeschaltetem Fernlicht nähern. Bei Ausrüstung aller Fahrzeuge mit dieser Be^Lndschutzvorrichtung ist, solange Gegenverkehr ausbleibt, kein Abblenden mehr erforderlich, die Verkehrssicherheit wird hierdurch erheblich gesteigert.any desired light attenuation can be achieved »A complete one t Crossing the directions of oscillation would be inexpedient because in this case the following vehicle would be completely invisible in the rearview mirror. Of course-J This arrangement can also weaken or extinguish daylight will. It is therefore useful to determine the directions of oscillation of the foils set in parallel during the day, so that in retrospect there is sufficient brightness is available. The method described comes into effect without the following vehicle being equipped with polarized headlights Particularly good protection against road users who are item's own vehicle approach too close with the high beam switched on. If all vehicles are equipped with this protective device, as long as there is no oncoming traffic, there is no More stopping down is required, this considerably increases road safety.

Die Irfindun g wird an einem Ausführungsbeispiel erläutert. In der Zeichnung ist die Durchsicht durch ein Kraftfahrzeug von der Rückscheibe zur Frontscheibe ^dargestellt. Mit 1 ist die Rückscheibe bezeichnet, die etwa zur Hälfte mit einer durchsichtigen polarisierenden Folie 2, dem Polarisator, beklebt ist. Die von rechts oben nach links unten verlaufende Schraffur deutet die Richtung an, in welcher das von hinten durch das Rückfenster eintretende Licht weiterschwingen kann. Mit 3 ist der in ETähe der Frontscheibe befestigte Spiegel bezeichnet, der mit einer durchsichtigen Polarisationsfolie ( Analysator) beklebt ist. Die Schwingungsrichtung des Analysators ist durch die von links oben nach rechts unten verlaufende Sohraffur verdeutlicht. Die Schwingungsrichtung des Polarisators zu der des Analysators bildet zweckmässigerweise einen Winkel, ^er von 9o°, z.B. um Ιο0, verschieden ist, damit dem Auge des Fahrerfs die Scheinwerfer des ihm folgenden Fahrzeuges noch als schwache Lichtquelle erkennbar bleiben. Es ist möglich, die bereits bekannten Rückfensterfolien, die ein Beschlagen der Glasscheibe verhüten^ als Polarisationsfolie auszubilden, um sie somit einem doppelten Verwendungszweck zugänglich zu machen.The Irfindun g is explained using an exemplary embodiment. In the drawing, the view through a motor vehicle from the rear window to the front window is shown. 1 with the rear pane is designated, about half of which is covered with a transparent polarizing film 2, the polarizer. The hatching running from top right to bottom left indicates the direction in which the light entering from behind through the rear window can continue to oscillate. 3 with the mirror attached near the windshield is referred to, which is covered with a transparent polarizing film (analyzer). The direction of oscillation of the analyzer is illustrated by the sohraffur running from top left to bottom right. The direction of oscillation of the polarizer to that of the analyzer expediently forms an angle that differs from 90 °, for example by Ιο 0 , so that the driver's eye can still see the headlights of the vehicle following him as a weak light source. It is possible to design the already known rear window foils, which prevent the glass pane from fogging up, as polarizing foils in order to make them accessible for a dual purpose.
