Gelöst wird die Aufgabe erfindungsgemäß dadurch, dass die Signalinformation für den Fahrer eines nachfolgenden Fahrzeugs auf der reflektierenden Fläche der Heckscheibe oder außerhalb der Heckscheibe des Kraftfahrzeugs als Warndreieck in Erscheinung tritt. In Pannensituationen, besonders auf Autobahnen, ist das Warnen des nachfolgenden Verkehrs mit Hilfe eines Warndreiecks in ausreichender Entfernung zwingend vorgeschrieben. Jedoch ist dies aufgrund des dichten Verkehrs auf der Bundesautobahn oft mit einem erheblichen Risiko für die betreffende Person verbunden, die das Warndreieck aufzustellen hat. Die erfindungsgemäße Warnvorrichtung schließt diese Gefahr aus, da mit ihr unmittelbar nach Unfällen der nachfolgende Fahrer eines Kraftfahrzeugs frühzeitig gut wahrnehmbar informiert werden kann, ohne dass der Fahrer das vorausfahrende Fahrzeug verlassen muss. Die Insassen können im Fahrzeug die Warnvorrichtung aktivieren, so dass das Warnsignal sofort als Warndreieck auf der Heckscheibe sichtbar wird. Ebenso ist es möglich, die Warneinrichtung auch außerhalb des Fahrzeugs in Betrieb zu setzen, beispielsweise über eine Schalttaste am Zündschlüssel.Is solved the task according to the invention by that the signal information for the driver of a subsequent vehicle on the reflective area the rear window or outside the rear window of the vehicle as a warning triangle in appearance occurs. In breakdown situations, especially on highways, is the warning the subsequent traffic with the help of a warning triangle in sufficient Distance mandatory. However, this is due to the dense traffic on the federal highway often with a considerable Risk for connected to the person in question who set up the warning triangle Has. The warning device according to the invention includes this danger, since with her immediately after accidents the subsequent drivers of a motor vehicle are well informed early enough can without the driver leaving the vehicle in front got to. The inmates can in the vehicle, activate the warning device, leaving the warning signal Immediately visible as a warning triangle on the rear window. As well is it possible that Warning device also outside of the vehicle in operation, for example via a Switch button on the ignition key.
Vorteilhaft ist es auch, dass der einen gebündelten Lichtstrahl aussendende Laserlichtstrahler oder Laserprojektor die Signalinformation als Warnzeichen außerhalb der Windschutzscheibe auf eine Nebelwand oder ein ähnliches Medium projiziert. Durch die gleiche Laserdiode kann bei Nebel oder anderen Sichtbeeinträchtigungen ein holographisches Warndreieck aus dem Fahrzeug heraus auf den Nebel projiziert werden. Rauch eignet sich aus als Projektionsfläche für geometrische Formen. Je nach Stärke der Sichtbeeinträchtigung kann der Warnhinweis sehr schnell auf weite Distanzen sehr gut sichtbar abgebildet werden. Das bekannte Warnblinklicht oder Warndreieck ist nur auf sehr kurze Entfernung ausreichend sichtbar. Mit der erfindungsgemäßen Einrichtung kann unmittelbar nach Unfällen, insbesondere auf Autobahnen der nachfolgende Fahrer eines Kraftfahrzeugs frühzeitig gut wahrnehmbar informiert werden, ohne dass die Insassen hierzu sofort das Fahrzeug verlassen müssen. Ebenso ist es möglich, dass die Warneinrichtung bei Auftreten einer Störgröße automatisch eingeschaltet und das Warndreieck im Heckbereich des Fahrzeugs sichtbar gemacht wird.Advantageous It is also that one bundled Light beam emitting laser light emitters or laser projectors which Signal information as a warning sign outside the windshield on a smoke screen or similar Medium projected. By the same laser diode can work in fog or other visual impairments a holographic warning triangle out of the vehicle on the Mist be projected. Smoke is suitable as a projection surface for geometric To shape. Depending on the strength the visual impairment the warning message can very quickly be seen very clearly at long distances be imaged. The well-known hazard warning light or warning triangle is sufficiently visible only at very short distance. With the inventive device can immediately after accidents, in particular on highways the subsequent driver of a motor vehicle early be well discernible without the occupants to do so Immediately leave the vehicle. It is also possible that the warning device automatically switched on when a disturbance occurs and the warning triangle in the rear of the vehicle made visible becomes.

Durch Auslösen des Warnblinklichtes projiziert beispielsweise eine rote Laserdiode auf einer reflektierenden Fläche eines Heckfensters des Fahrzeugs ein rotes Warndreieck. Das hierzu verwendete Verbundglas des Heckfensters hat als Projektionswand sehr gute Leitungseigenschaften und kann das abgegebene Licht erheblich verstärken. Je nach Lichtleistung der Diode kann die Leuchtkraft gegenüber einem herkömmlichen Warndreieck oder einem Warnblinklicht erheblich höher liegen. Damit kann die Frühwarnzeit für den nachfolgenden Verkehr erheblich erhöht werden. Der Fahrzeuginsasse braucht hierzu das Fahrzeug nicht mehr zu verlassen. Die Sicherheit für die Fahrzeuginsassen wird durch diese Warnvorrichtung wesentlich verbessert.By Trigger the hazard warning light projects, for example, a red laser diode on a reflective surface a rear window of the vehicle a red warning triangle. This used laminated glass of the rear window has as a projection screen very good conductor properties and can the emitted light considerably strengthen. Depending on the light output of the diode, the luminosity compared to a usual Warning triangle or a hazard warning light are significantly higher. This can the early warning for the significantly increased in subsequent traffic. The vehicle occupant does not need to leave the vehicle for this purpose. The security for the Vehicle occupants are significantly improved by this warning device.
Die Signalinformation für den Fahrer eines nachfolgenden Fahrzeugs kann nicht nur auf der reflektierenden Fläche der Heckscheibe, sondern auch außerhalb der Heckscheibe des Kraftfahrzeuges als Warndreieck in Erscheinung treten.The Signal information for the driver of a subsequent vehicle can not only on the reflective surface the rear window, but also outside the rear window of the Motor vehicle as a warning triangle in appearance.
Durch die gleiche Laserdiode der Warnvorrichtung kann auch bei auftretendem Nebel oder anderen Sichtbeeinträchtigungen ein Warndreieck auch außerhalb des Fahrzeugs sichtbar gemacht werden. Mit Hilfe der erfindungsgemäßen Warnvorrichtung kann die Wiedergabe von Bildern in dreidimensionaler Struktur in zwei zeitlich voneinander getrennten Schritten durch das kohärente Licht von Laserstrahlen erzeugt werden und dadurch auch auf Nebelwänden ein Warndreieck projiziert werden. Rauch eignet sich als sehr gute Projektionsfläche für geometrische Formen. Je nach Stärke der Sichtbeeinträchtigung kann der Warnhinweis auf weite Distanzen sehr gut sichtbar abgebildet werden.By the same laser diode of the warning device can also occur when Fog or other visual impairments a warning triangle also outside be made visible to the vehicle. With the help of the warning device according to the invention can the reproduction of images in three-dimensional structure in two temporally separate steps through the coherent light produced by laser beams and thereby also on fog walls Warning triangle will be projected. Smoke is a very good projection surface for geometric shapes. Depending on the strength the visual impairment can the warning message is clearly visible over long distances become.
