Abstract

The optical unit for a motor vehicle, which has a double glazed front windscreen with a cavity under vacuum between the panels. At least one compressed air cartridge is connected at the cavity of the screen. Which with a forceful operation of the ignition key or a short circuit in the ignition region is activatable. The compressed air/colour mixture upon activation in the cavity between the windscreen panes, forms a non-transparent (opaque) coating on the inner surface of the windscreen, making it impossible to see through the windscreen and impossible to drive the vehicle away.

Description

Die Erfindung betrifft eine optische Einrichtung zur Anzeige und zur Verhinderung des unbefugten Gebrauchs eines Kraftfahrzeuges, welches eine doppeltverglaste Frontscheibe mit einem unter Vakuum stehenden Hohlraum zwischen den Scheiben aufweist.The invention relates to an optical device for Notification and prevention of unauthorized use of a Motor vehicle, which has a double-glazed front window with a cavity under vacuum between the Has discs.

Aus DE-A 43 32 278 ist eine optische Einrichtung zur Anzeige des unbefugten Gebrauchs eines Kraftfahrzeuges bekannt, welche eine doppeltverglaste Seitenscheibe oder eine doppeltverglaste Rückscheibe aufweist und im übrigen mit einem Alarmsystem herkömmlicher Bauart ausgerüstet ist. Spricht das Alarmsystem bei unbefugtem Gebrauch des Fahrzeuges an, so wird ein farbiges Gas in den Zwischenraum der Doppelverglasung eingeleitet unter Einfärbung der doppeltverglasten Scheibe. Um die Signalwirkung zu erhöhen ist es bekannt, eine innenliegende Folie der doppelt­ verglasten Scheibe mit einem Strömungskanal in Form eines Schriftzuges, der auf den unbefugten Gebrauch hinweist zu versehen. Bei unbefugtem Gebrauch wird beispielsweise ein Schriftzug "dieses Fahrzeug wurde gestohlen" durch das in die Verglasung einströmende farbige Gas sichtbar. Die Einfärbung des Glases kann rückgängig gemacht werden, indem ein Entlüftungsventil an der Scheibe geöffnet und der Durchströmungsraum der Scheibe mit einem farblosen Gas gespült wird.From DE-A 43 32 278 an optical device for Notification of unauthorized use of a motor vehicle known which is a double glazed side window or has a double-glazed rear window and the rest is equipped with an alarm system of conventional design. Does the alarm system speak in the event of unauthorized use of the Vehicle, there is a colored gas in the gap the double glazing initiated by coloring the double glazed pane. To increase the signal effect it is known to have an inner double layer glazed pane with a flow channel in the form of a Lettering that indicates the unauthorized use Mistake. With unauthorized use, for example, a Lettering "this vehicle was stolen" by the in colored gas flowing into the glazing is visible. The Coloring the glass can be reversed by a vent valve on the pane opened and the Flow-through space of the disc with a colorless gas is rinsed.

Die bekannte Vorrichtung zeigt den unbefugten Gebrauch eines Kraftfahrzeuges zwar an, doch bleibt das Fahrzeug verkehrstüchtig. Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung anzugeben, die den unbefugten Gebrauch des Fahrzeuges nicht nur anzeigt sondern das Wegfahren des Fahrzeuges durch eine Blicksperre praktisch unmöglich macht.The known device shows the unauthorized use of a motor vehicle, but the vehicle remains roadworthy. The invention is based on the object  to specify a device that prevents unauthorized use of the Vehicle not only indicates but the driving away of the The vehicle is practically impossible due to an eye lock makes.

Zur Lösung dieser Aufgabe lehrt die Erfindung, daß an den unter Vakuum stehenden Hohlraum der doppeltverglasten Frontscheibe mindestens eine mit einer Signalfarbe gefüllte Druckluftpatrone angeschlossen ist, die bei einer gewalt­ samen Betätigung des Zündschlosses oder bei einem Kurz­ schluß im Zündbereich aktivierbar ist, wobei das Druck­ luft/Farbgemisch bei einer Aktivierung in den Hohlraum der Frontscheibe einschießt und auf den Innenflächen der Scheiben einen undurchsichtigen Belag bildet.To achieve this object, the invention teaches that to the double-glazed cavity under vacuum Front window at least one filled with a signal color Compressed air cartridge is connected in case of violence complete actuation of the ignition lock or for a short circuit can be activated in the ignition area, the pressure air / color mixture when activated in the cavity of the Windshields and on the inner surfaces of the Discs forms an opaque coating.
