"Einrichtung zur Darbietung eines Bildes im Kraftfahrzeug""Device for presenting an image in a motor vehicle"
Für den Kraftwagenfahrer ist es wichtig,- die hinter ihm liegende Fahrbahn in möglichst voller Breite als Bild im Fahrzeug zur Verfügung zu haben, um z.B. ihm nachfolgende und/oder zum Überholen ansetzende Fahrzeug« beobachten zu können.It is important for the truck driver - those behind him to have the full width of the lying lane available as an image in the vehicle, e.g. to follow it and / or vehicles preparing to overtake «.
Zwar gehören bereits außen und innen am Fahrzeug angebrachte Rückapiegel zur notwendigen Ausrüstung des Kraftfahrzeugs, doch haben diese Nachteile aufzuweisen. Der außen seitlich angebrachte Rückspiegel hat den Mangel, daß von ihm wegen der Sichtbehinderung ,durch das eigene Fahrzeug ein nur vollständiges Bild dargeboten wird. Der innen vorgesehene Rückspiegel (Mittenspiegel) ist dann wirkungslos, wenn das seine Lichteintrittsfläche darstellende Rückfenster verschmutzt, beschlagen oder vereiat ist, wobei, was nur nebenbei erwähnt sei, zu dessen Aufheizung größere Energien erforderlich sind. Beiden Spiegeln haften die Nachteile an, daß der Raum unmittelbar hinter dem eigenen Fahrzeug, nicht erfaßt werden und daß durch falsche Einstellungen oder ungewollte Verstellungen die gewünschte Bilddarbietung eingeengt oder aufgehoben sein kann. Auch kann ihre ,Beobachtung den Fahrer von derAlthough rearview mirrors attached to the outside and inside of the vehicle are part of the necessary equipment of the motor vehicle, they have disadvantages. The rearview mirror attached to the side on the outside has the disadvantage that only a complete picture is presented of it because of the visual impairment caused by one's own vehicle. The rear-view mirror (center mirror) provided on the inside is then ineffective if the rear window, which is its light entry surface, is dirty, fogged up or iced up, whereby, which should only be mentioned in passing, greater energies are required to heat it. Both mirrors have the disadvantages that the space immediately behind the vehicle is not covered and that the desired image presentation can be restricted or canceled due to incorrect settings or unwanted adjustments. Also can their, observation the driver from the

Die Erfindung, welche sich die Vermeidung dieser Nachteil« zum Ziele gesetzt hat, besteht in ihrem Grundgedanken därin, daß an der Fahrzeugrückseite ein ein Bild der zurückliegenden Fahrbahn aufnehmendes und im Fahrseuginnern ein dieses Bild wiedergebendes Organ vorgesehen sind, wobei diese Organe durch ein optisches Übertragungsmittel miteinander verbunden sind*The invention, which avoids this disadvantage « has set the goal, consists in its basic idea that on the back of the vehicle a picture of the past The lane recording and an organ reproducing this image are provided in the interior of the Fahrseuginnern, wherein these organs with each other through an optical transmission medium are connected*
Nach einer bevorzugten AusfÜhrungsform der Erfindung bestehen das Aufnahme- und V/i ed ergäbe organ aus den Lichteintritts- und -austrittsflachen einer beide Organe verbindenden Glasfaseroptik.According to a preferred embodiment of the invention, the receiving and V / i ed would consist of the light entry and exit surfaces of a connecting both organs Fiber optics.
Der die beiden genannten Flächen verbindende Glasfaserachlauch kann außen am Wagen oder im Wageninnern zur Beobachtungsstelle durchgeleitet werden. The glass fiber tube connecting the two surfaces mentioned can be passed through to the observation point on the outside of the car or inside the car.
Ein wesentliches Merkmal der Erfindung wird darin gesehen, daß die Glasfaseroptik an ihren Lichteintritts- und -austrittsflächen einen im Verhältnis zu dem sie verbindenden Übertragungsschlauch größeren Querschnitt aufweist. Das bedeutet also, daß die einzelnen Glasfasern sich von den Lichteintritts- und -austrittsflachen ab verjüngen, eo daß Aufnahme und Wiedergabe des Bildes in ungefähr gleicher vorteilhafter Größe und mit ausreichendem AuflöeungeVermögen erfolgen, während der beide Flächen verbindende Glas* An essential feature of the invention is seen in the fact that the glass fiber optics on their light entry and exit surfaces has a larger cross-section in relation to the transmission hose connecting them. That means that the individual glass fibers taper from the light entry and exit surfaces, eo that Recording and reproduction of the image in approximately the same of an advantageous size and with sufficient resolution, while the glass connecting the two surfaces *

Die Austritts-(Bildwiedergabe-)fläehe der Faseroptik muß sich im engeren Sichtumkreis des Fahrers befinden. Vorzugsweise ist sie am oder im Armaturenbrett vorgesehen.The exit (image display) surface of the fiber optics must are in the driver's immediate field of vision. It is preferably provided on or in the dashboard.
Durch ein bestimmtes Querschnittverhältnis der Fasern an Lichteintritts- und -austrittsfläche kann zwar bereits eine Bilddehnung erzielt werden. Zur Herbeiführung einer stärkeren Vergrößerung empfiehlt es sich, die Glasfaseroptik zu einem Fernrohr zu vervollständigen, indem der an der Fahrzeugrückseite vorgesehenen Lichteintrittsfläche ein Objektiv, vorzugsweise ein Weitwinkelobjektiv, vorgesetzt und der Lichtaustrittsfläche im Fahrzeuginnern ein Okular, vorzugsweise ein Weitwinkelokular, nachgeschaltet wird. Eine aufrechte und seitenrichtige Wiedergabe des Bildes kann durch entsprechende Verdrehung (Verwindung) des Glasfaserschlauchs erreicht werden.A certain cross-sectional ratio of the fibers on the light entry and exit surfaces can already image stretching can be achieved. To achieve a higher magnification, it is advisable to use fiber optics to complete a telescope by using the light entry surface provided on the rear of the vehicle a lens, preferably a wide-angle lens, placed in front and the light exit surface in the vehicle interior Eyepiece, preferably a wide-angle eyepiece, is connected downstream. An upright and laterally correct reproduction of the Image can be achieved by corresponding twisting (twisting) of the glass fiber tube.
Zur Verhinderung des Beschlagens bzw. zur Enteisung wird die Glasfaseroptik vorteilhaft mit einer Heizeinrichtung (Heizwicklung) versehen. Auch kann an der Lichteintrittaflache eine Regenschute oder Taukappe vorgesehen sein.To prevent fogging or de-icing, the glass fiber optics are advantageously equipped with a heating device (Heating coil) provided. Can also be on the light entry surface a rain hood or dew cap may be provided.
Die Erfindung wird anhand der in den Figuren 1 und 2 dargestellten AusführungsbeispieJLs näher erläutert*The invention is illustrated with reference to FIGS. 1 and 2 Execution examples explained in more detail *

die Lichteintrittsfläche 3 der Glasfaseroptik 4 angebracht ist. Die Anbringung und Ausrichtung dieser Fläche 3 er^ folgt so, daß unter geringster Abdeckung durch die rückwärtigen Karosserieteile ein möglichst umfassendes Bild der zurückliegenden Fahrbahn bis dicht an das Kraftfahrzeug selbst aufgenommen werden kann. Der in diesem Beispiel im Fahrzeuginnern verlegte Glasfaserschlauch 4 endet mit seiner Lichtaustrittsfläche 5 am Armaturenbrett 6, und zwar dort, wo die Beobachtung durch den Fahrer mit geringster Blickwendung von der Geradeaussicht möglich ist. 7 ist eine Heizwicklung zur Verhinderung des Beschlagens der Fläche 3 bzw. zu deren Abtauen, 8 eine Regenschute.the light entry surface 3 of the glass fiber optics 4 is attached. The attachment and alignment of this surface 3 he ^ follows in such a way that a picture as comprehensive as possible is obtained with the least possible coverage by the rear body panels the previous lane can be taken up close to the motor vehicle itself. The one in this example The fiberglass hose 4 installed inside the vehicle ends with its light exit surface 5 on the dashboard 6, and where it is possible for the driver to observe with the slightest turning of his gaze from a straight line of sight. 7th is a heating coil to prevent fogging of the surface 3 or to defrost it, 8 is a rain cover.
Durch die Fig. 2 soll der Querschnitt-Unterschied zwischen der Lichteintritts- und -austrittsfläche einerseits und dem Ubertragungsschlauch der Glasfaseroptik andererseits veranschaulicht werden. Wie man erkennt, besitzen die einzelnen Glasfasern an ihren Enden den jeweils größten Querschnitt und verjüngen sich dann, beispielsweise bis auf das 5-fache, so daß Apertur und Auslösungsvermögen an den Endflächen zwar relativ groß sind, der Durchmesser des ÜbertragungsBchlauches dagegen gering wird, mit 9 und 10 sind ein Objektiv und eine Betrachtungslupe angedeutet.By Fig. 2, the cross-sectional difference between the light entry and exit surface on the one hand and the transmission tube of the glass fiber optics on the other hand illustrated. As you can see, the individual glass fibers have the largest at their ends Cross-section and then taper, for example up to 5 times, so that the aperture and resolution are relatively large at the end faces, but the diameter of the transfer tube is small, with 9 and A lens and a viewing magnifier are indicated.
