Abstract

The dashboard of the military vehicle has an illuminating plate with a collimating grille behind. The grille directs the light from the instruments etc. directly to the face of the driver, with no stray light to be seen by aircraft etc. The grille is made from an array of opaque slats. The dashboard itself is made from a double layer glass with a liquid crystal in between to control the illumination as well as to provide any display information.

Description

Die Erfidnung betrifft ein Armaturenbrett für Kraftfahr-The invention relates to a dashboard for motor vehicles

zeuge, insbesondere für Militärkraftfahrzeuge.tools, especially for military vehicles.

Die Armaturenbretter von kraftfahrzeugen verbreiten oftmals ein insbesondere den Fahrer blendendes und störendes Licht.The dashboards of automobiles often spread a particular dazzling and annoying light for the driver.

Bei im Nachteinsatz stehen Militär-Lastkraftwagen, insbesondere bei solchen niit offenem Fahrergehäuse, stellt ein stark leuchtendes Armaturenbrett eine akute Gefahr dar, da feindliche Luftaufklarung derartige Lastkraftwegen unverzüglich orten würden.When deployed at night, military trucks, in particular, are available such with the driver's cab open, the dashboard is brightly illuminated pose an acute danger, since enemy aerial reconnaissance immediately takes such heavy haulage routes would locate.

Der Erfiundung leigt die Aufagbe zugrunde, ein derartiges dem Armaturenbrett von Kraftfahrzeugen stammendes, blendendes und verräterisches Licht zu vermeiden.The invention is based on the task, such as the dashboard Avoid glare and tell-tale light from motor vehicles.

Gelöst wird diese Aufgabe nach der Erfindung durch ein Armaturenbrett mit einer durchsichtigen Abdeckscheibe, in. welche jalousieartig angeordnete, zueinander parallel verlaufende Lamellen aus lichtundurchlässigem Werkstoff eingelassen sind, die in einer solchen Winkelstellung im Fahrzeug eingebaut sind, daß die zwischen den Lamellen in deren Richturlg austretenden Lichtstrahlen nur einen Raum bis knapp oberhalb Augenhöhe des Kraftfahrzeugfahrers ausfüllen.This object is achieved according to the invention by a dashboard with a transparent cover plate, in which blind-like arranged, to each other parallel slats made of opaque material are embedded, which are installed in such an angular position in the vehicle that the between the lamellas in the direction of the light rays exiting only a space or just under Fill in above the driver's eye level.

Zweckmäßig ist die durchsichtige Lamellenabdeckscheibe mit einer zwischen zwei Glasscheiben angeordneten Flüssigkeitskristallschicht belegt.The transparent lamellar cover plate with an between liquid crystal layer arranged on two panes of glass.

Nachfolgend wird anhand der Zeichnung eine Ausführungsform der Erfindung näher erläutert.An embodiment of the invention is described below with reference to the drawing explained in more detail.

Es zeigen Figur 1 : einen Ausschnitt einer Seitenansicht eines Fahrergehäuses und Figur 2 t eine Detailseitenansicht in vergrößertem Maßstab.FIG. 1 shows a detail of a side view of a driver's housing and FIG. 2 t shows a detail side view on an enlarged scale.

Die durchsichtige Abdeckscheibe 1 deckt das Armaturenbrett des Kraftfahrzeugs 3 ab. Es besitzt jalousieartig angeordnete, zueinander parallel verlaufende eingelassene Lamellen 2 aus lichtundurchlässigem Werkstoff. Diese lassen das vnn den Lichtquellen hinter dem Armaturenbrett ausgehende Licht nur parallel zu den Lamellen 2 in Richtung der Lichtstrahlen 4 austreten, die das Gesichtsfeld des Fahrers 5 treffen.The transparent cover panel 1 covers the dashboard of the motor vehicle 3 from. It has louvre-like, recessed, parallel to each other Slats 2 made of opaque material. These leave that from the light sources light emanating from behind the dashboard only parallel to the slats 2 in the direction of the light rays 4 exit, which hit the field of view of the driver 5.

Da die Winkelstellung alpha dieser durch die Lamellen 2 hindurchtretenden Lichtstrahlen 4 in Bezug auf das Lot L derart gewählt ist, daß die Lichtstrahlen 4 nur einen Raum bis knapp oberhalb Augenhöhe des Kraftfahrzeugefahrers 5 ausfüllen, ist hierdurch gewährleistet, daß keinerlei störende oder verräterische Lichtstrahlen die Windschutzscheibe 11 durchdringen oder nach oben aus dem entfernten Fahrerhausdach 12 austreten kann. Ein feindliches Beobachtungsflugzeug könnte also kein leuchtendes Armaturenbrett eines solchen Militärlastkraftwagens observieren und lokalisieren, da es sich in Jedem Falle in den Bereich 9 befindet, welcher durch die Lichtstrahlen 4 nicht ausgefüllt wird.Since the angular position alpha of these passing through the slats 2 Light rays 4 with respect to the solder L is chosen such that the light rays 4 only fill a space up to just above eye level of the motor vehicle driver 5, this ensures that there are no disturbing or telltale rays of light penetrate the windshield 11 or up from the removed cab roof 12 can emerge. An enemy observation aircraft could not be a shining one Observe and locate the dashboard of such a military truck, since it is in any case in the area 9, which is through the light rays 4 is not completed.

Das in Figur 1 durch den Kreis 10 eingegrenzte Teil ist in Figur 2 in vergrößertem Maßstab dargestellt und zeigt eine abgewandelte Ausführungsform, bei welcher die durchsichtige Lamellenabdeckscheibe 1, 2 durch zwei Glasscheiben 6,7 belegt ist, zwischen denen eine Flüssigkeitskristallschicht 8 angeordnet ist.The part delimited by the circle 10 in FIG. 1 is shown in FIG shown on an enlarged scale and shows a modified embodiment, in which the transparent lamella cover 1, 2 through two panes of glass 6.7 is occupied, between which a liquid crystal layer 8 is arranged.

Letztere zusätzliche Vorrichtung gestattet noch eine Vergrößerung des Winkels alpha, so daß der Fahrer 5 nicht auf direkt ins Auge auftreffende Lichtstrahlen 4 angewiesen ist, sondern deren Sekundärwirkung beobachten kann, welche von den Flüssigkeitskristallen ausgeht. Auch hierbei ergibt sich ein zwar für den Kraftfahrzeugfahrer kontrestreich erkennbares Signalbild, das jedoch so lichtschwach ist, daß es von keinem tieffliegendem Beobachtungsflugzeug erkannt werden kann.The latter additional device still allows an enlargement of the angle alpha, so that the driver 5 does not have to deal with light rays striking the eye directly 4, but whose secondary effect can be observed, which of the Runs out of liquid crystals. This also results in a situation for the motor vehicle driver Contrastingly recognizable signal image, which is so faint that it is of cannot be detected by any low-flying observation aircraft.
