Abstract

Conventional mirrors which can be dipped can be easily misadjusted during tilting, or their construction is susceptible to failure. The novel mirror which can be dipped is intended to reduce the reflectivity (reflecting power) continuously without mechanical manipulation. The light which infringes, through a mirror surface which is coated on one side, upon a sensor is intended to control, by means of a corresponding circuit, a light source which changes the reflectivity of the mirror surface continuously. The field of use is in motor vehicles as interior and exterior mirrors.

Description

Die Erfindung betrifft einen Spiegel, insbesondere einen abblendbaren Rückblickspiegel für Kraftfahrzeuge.The invention relates to a mirror, in particular one dimmable rear view mirror for motor vehicles.

Bei Nachtfahrten von Kraftfahrzeugen stört das auf die Rückblickspiegel von hinten auftreffende Licht den Führer des Kraftfahrzeuges. Es ist daher bekannt, abblendbare Spiegel vorzusehen, die in der Regel ein schwenkbares Prisma enthalten, das von Hand bei einem abblenden des Spiegels in eine andere Position gekippt wird. Die dann reflektierende Fläche des Prismas weist ein vermindertes Reflektionsvermögen auf.When driving motor vehicles at night, this bothers Rearview mirror light hitting the guide from behind of the motor vehicle. It is therefore known to be dimmable To provide mirrors, which are usually a swivel Prism included, by hand when dimming the Mirror is tilted to another position. The then reflective surface of the prism has a diminished Reflectivity.

Weiter ist bekannt, durch Flüssigkristalle zwischen Glasplatten und auf diesen aufgebrachte Polarisations­ filter mit zugehöriger Steuerung die Reflektion zu ver­ mindern (DBP 27 32 727.1).It is also known to be between liquid crystals Glass plates and polarization applied to them filter with associated control to ver the reflection reduce (DBP 27 32 727.1).

Die bekannten abblendbaren Rückblickspiegel weisen aber Nachteile auf. So kann beim Kippen des schwenkbaren Pris­ mas der Spiegel unabsichtlich leicht verstellt werden, was eine Nachjustierung erforderlich macht. Die Anwendung dieses Prinzipes auf Kraftfahrzeug-Außenspiegel ist nicht üblich. Oder aber Aufbau und Konstruktion der Abblende­ einrichtung sind kompliziert und störanfällig sowie mit hohen Kosten verbunden. Das wirkt sich nachteilig auf die Betriebs- und Verkehrssicherheit aus.The well-known dimmable rearview mirrors have Disadvantages. So when tilting the pivoting pris mas the mirror unintentionally easily adjusted what readjustment is necessary. The application this principle on motor vehicle wing mirrors is not common. Or the structure and construction of the aperture furnishings are complicated and prone to failure as well as with associated with high costs. That adversely affects the  Operational and traffic safety.

Es ist daher das Ziel der Erfindung, einen Spiegel, ins­ besondere einen abblendbaren Rückblickspiegel für Kraft­ fahrzeuge vorzusehen, der die Nachteile der bekannten Einrichtungen vermeidet und es ermöglicht, das Reflek­ tionsvermögen während des Abblendvorganges ohne ein Eingreifen des Kraftfahrzeugführers stufenlos veränderlich zu verringern.It is therefore the object of the invention to provide a mirror special a dimmable rearview mirror for power to provide vehicles that have the disadvantages of the known Avoids facilities and allows the reflect ability during the dimming process without one Intervention of the driver is infinitely variable to reduce.

Das Ziel der Erfindung wird durch die im Hauptanspruch gekennzeichneten Merkmale erreicht. Zweckmäßige Ausge­ staltungen der Erfindung sind in den Unteransprüchen dar­ gestellt.The aim of the invention is defined in the main claim marked features achieved. Appropriate Ausge Events of the invention are set out in the dependent claims posed.

Die Erfindung wird in der Zeichnung prinzipiell darge­ stellt und wie folgt näher beschrieben:The invention is principally Darge in the drawing and described in more detail as follows:

Ein Ausführungsbeispiel der erfindungsgemäßen Einrich­ tung enthält eine Platte 1 aus Plastikmaterial oder Glas, die mit einer Reflektionsfläche 2 auf der Vorderseite versehen ist. Derartige Einrichtungen sind bekannt und werden nicht näher beschrieben. Die Platte 1 wird von einem Gehäuse 3 aus Plastikmaterial oder Metall rückseitig eingefaßt. Das Gehäuse 3 enthält eine Öffnung 4 zur Aufnahme der Platine 5, auf deren Vorderseite 6 eine Lichtquelle 7, z. B. eine Soffitenlampe, und ein mit einer seitlichen Abschirmung 8 versehener Sensor 9 aufgebracht sind. Auf der Rückseite der Platine 5 ist die notwendige Steuerung 10 zwischen Lichtquelle 7 und Sensor 9 auf­ gebracht. Die Platine ist mittels lösbarer Steckver­ bindungen durch Kabel 11 an das Stromnetz des Kraftfahr­ zeuges angeschlossen.An embodiment of the Einrich device according to the invention contains a plate 1 made of plastic or glass, which is provided with a reflective surface 2 on the front. Such devices are known and are not described in detail. The plate 1 is bordered on the back by a housing 3 made of plastic material or metal. The housing 3 contains an opening 4 for receiving the board 5 , on the front 6 a light source 7 , z. B. a soffit lamp, and a sensor 9 provided with a side shield 8 are applied. On the back of the board 5 , the necessary control 10 is brought between the light source 7 and sensor 9 . The board is connected by means of releasable plug connections through cables 11 to the power supply of the vehicle.

Im Normalbetrieb wird das einfallende Licht von der Reflektionsfläche 2 ungemindert reflektiert, da der Sensor 9 und die Steuerung 10 auf Grund der geringen Lichtmenge nicht ansprechen. Stärker einfallendes Licht, d. h. bei eintretender Blendwirkung, veranlaßt den Sensor 9 zur Erzeugung einer Steuerspannung, mittels derer über die Steuerung 10 Strom zur Lichtquelle 7 fließt. Dadurch wird die Platte 1 von der rückwärtigen Seite her beleuchtet. Die Reflektion wird verringert, so daß die Blendwirkung des einfallenden Lichtes aufgehoben wird.In normal operation, the incident light is reflected undiminished by the reflection surface 2 , since the sensor 9 and the controller 10 do not respond due to the small amount of light. More intense light, ie when glare occurs, causes the sensor 9 to generate a control voltage by means of which current flows to the light source 7 via the controller 10 . As a result, the plate 1 is illuminated from the rear side. The reflection is reduced so that the glare of the incident light is eliminated.

Der Vorgang läuft ohne notwendige Manipulationen durch den Kraftfahrzeugführer ab.The process runs without necessary manipulation by the Motorists from.
