Description

Die Erfindung betrifft eine Schutzvorrichtung gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a protective device according to the preamble of Claim 1.

Die gattungbildende DT 1 806 595 beschreibt ein Wasserwerferfahrzeug, vor dessen Frontscheibe sich in seiner Betriebsstellung ein Schutzgitter von netzartiger Struktur befindet; wird es nicht gebraucht, ist es um eine in Dachhöhe querverlaufende Schwenkachse hochgeschwenkt, so daß der Fahrerdurchblick durch die Windschutzscheibe nicht beeinträchtigt wird. Diese Schutzvorrichtung, die also von Hand im Bedarfsfalle verschwenkt wird, dient dem Schutz der Windschutzscheibe gegen das Auftreffen von geschleuderten Farbbeuteln, und zwar in der Weise, daß die Farbbeutel vom Schutzgitter aufgefangen und damit gehindert werden, auf die Windschutzscheibe aufzutreffen. Was eben bezüglich des Schutzes gegen Farbbeutel gesagt wurde, gilt auch für geworfene Gegenstände, insbesondere größere Steine. Insofern stellt der Stand der Technik auch eine Personenschutzvorrichtung dar, da das Eindringen dieser Steine in den Fahrgastraum verhindert wird.The generic DT 1 806 595 describes a water cannon vehicle, in front of it In its operating position, the front screen has a protective grille with a net-like structure located; if it is not used, it is a cross-section at roof level Swiveled axis pivoted up so that the driver can see through the Windshield is not affected. This protection device, so by hand is pivoted if necessary, serves to protect the windshield against Impact of flung paint bags, in such a way that the paint bags caught by the protective grille and thus prevented on the windshield encounter. What has just been said about protection against paint bags applies also for thrown objects, especially larger stones. In this respect, the stand technology also represents a personal protection device because the penetration of these stones is prevented in the passenger compartment.

Die Erfindung befaßt sich primär mit einem anderen Problem, nämlich dem Schutz von Personen gegen das Eindringen von Wildtieren bei einem Wildunfall. Die Wirkung der erfindungsgemäßen Schutzvorrichtung erstreckt sich jedoch auch auf die Verhinderung des unfallbedingten Eindringens irgendwelcher Gegenstände durch die Windschutzscheibe in den Fahrzeuginnenraum.The invention is primarily concerned with another problem, namely the protection of People against wildlife intrusion in a game accident. The effect of However, the protective device according to the invention also extends to prevention the accidental penetration of any objects by the Windshield in the vehicle interior.

Der Erfindung liegt mithin die Aufgabe zugrunde, eine gattungsgemäße Schutzvorrichtung so auszulegen, daß sie ohne Behinderung des normalen Fahrbetriebs, insbesondere ohne Beeinträchtigung der Fahrersicht während des Normalbetriebs des Fahrzeugs, einen wirksamen Schutz gegen das unfall- bzw. crashbedingte Eindringen von Gegenständen in den Fahrgastraum durch die Windschutzscheibe nach Zerstörung derselben bietet.The invention is therefore based on the object, a generic Protective device must be designed so that it does not interfere with normal driving, in particular without impairing the driver's view during normal operation of the Effective protection against accidental or crash-related intrusion  objects into the passenger compartment through the windshield after destruction the same offers.

Die erfindungsgemäße Lösung dieser Aufgabe besteht in den kennzeichnenden Merkmalen des Hauptanspruchs, vorteilhafte Ausbildungen der Erfindung beschreiben die Unteransprüche.The inventive solution to this problem consists in the characterizing Features of the main claim describe advantageous embodiments of the invention the subclaims.

Ein wesentliches Merkmal der erfindungsgemäßen Schutzvorrichtung besteht also in dem Precrash-Vorhandensein von Zugantrieben, die durch Precrash- oder Crashsensoren spätestens beim Beginn eines Crashs, bevorzugt aber bereits kurz vor dem Crash angesteuert bzw. gezündet werden, so daß die Windschutzscheibe rechtzeitig durch das Schutzgitter abgedeckt ist, bevor Gegenstände oder Tiere die Windschutzscheibe erreichen können. Ein anderes wesentliches Merkmal ist darin zu sehen, daß in normalen Betriebszuständen des Fahrzeugs praktisch bis zum Auftreten eines Crashs die Sicht des Fahrers durch die Windschutzscheibe nicht beeinträchtigt wird, da das Schutzgitter sich in seiner Ruhestellung etwa in Dachhöhe, bevorzugt in einem Dachschalenschacht, befindet. Nimmt man hinzu, daß die Zugantriebe in A- Säulen des Fahrzeugs untergebracht werden können, so ruft die erfindungsgemäße Schutzvorrichtung praktisch keine Beeinflussung des äußeren Eindrucks des Fahrzeugs hervor.An essential feature of the protective device according to the invention therefore consists in the pre-crash presence of train drives caused by pre-crash or Crash sensors at the latest when a crash begins, but preferably shortly before the crash controlled or ignited so that the windshield is covered in time by the protective grille before objects or animals Can reach the windshield. Another essential feature is there too see that in normal operating conditions of the vehicle practically until occurrence a crash does not affect the driver's view through the windshield is, since the protective grille in its rest position approximately at roof height, preferably in a roof shell shaft. If you add that the train drives in A- Pillars of the vehicle can be accommodated, so calls the invention Protective device practically no influence on the external impression of the vehicle forth.

An dieser Stelle sei eingefügt, daß die Schutzfunktion der erfindungsgemäßen Schutzvorrichtung sich auch auf das Zurückhalten von Fahrzeuginsassen erstreckt, die bei einem Auffahrunfall insbesondere dann, wenn sie nicht angeschnallt sind, nach vorn durch die Windschutzscheibe geschleudert werden. Die erfindungsgemäße Schutzvorrichtung verhindert dann eine gefährliche Bewegung des betreffenden Fahrzeuginsassen aus dem Fahrzeug heraus in Richtung auf den Unfallgegner.At this point it should be inserted that the protective function of the invention Protection device also extends to the restraint of vehicle occupants in the event of a rear-end collision, especially if they are not buckled up, forward to be thrown through the windshield. The invention Protective device then prevents dangerous movement of the person concerned Vehicle occupants out of the vehicle towards the opponent of the accident.

Nach dieser ersten Erläuterung der Erfindung sei zur Abrundung des Standes der Technik auf zwei Gebrauchsmuster hingewiesen. So beschreibt die G 90 01 013.2 U1 eine Schutzvorrichtung für eine Windschutzscheibe mit einer Schutzplatte, die sich in ihrer Ruhestellung in einem flachen Gehäuse auf dem Fahrzeugdach befindet und in ihrer Betriebsstellung aus diesem Gehäuse nach vorn herausgezogen ist, so daß sie die Windschutzscheibe horizontal überragt und gegen den Zutritt von Schnee schützt. Die DE 298 10 712 U1 betrifft ein Wetterschutzrollo für Automobile, dessen Gehäuse auf dem Fahrzeugdach befestigbar ist und dessen Folie mit Hilfe von Magnetstreifen nach ihrem Herausziehen aus dem Gehäuse am Fahrzeug festlegbar ist. In beiden Fällen handelt es sich nicht um eine Schutzvorrichtung im Sinne der Erfindung.After this first explanation of the invention, to round off the state of the art Technology pointed to two utility models. This is how the G 90 01 013.2 U1 describes it a protective device for a windshield with a protective plate, which is in their rest position is in a flat housing on the vehicle roof and in their operating position is pulled out of this housing to the front, so that they The windshield protrudes horizontally and protects against the ingress of snow. The DE 298 10 712 U1 relates to a weather protection roller blind for automobiles, the housing of which is on  can be attached to the vehicle roof and its film with the help of magnetic strips pulling them out of the housing on the vehicle can be fixed. In both cases it is not a protective device in the sense of the invention.

Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand der Zeichnung erläutert, die eine Vorderansicht des Windschutzscheibenbereichs eines mit der erfindungsgemäßen Schutzvorrichtung ausgestatteten Kraftfahrzeugs schematisch wiedergibt.An embodiment of the invention is described below with reference to the drawing explained, which is a front view of the windshield area one with the Protective device equipped motor vehicle according to the invention schematically reproduces.

Die Windschutzscheibe 1 ist beispielsweise bei einem Wildunfall dem Aufprall eines hochgeschleuderten Tieres ausgesetzt, das nach Zerstörung der Windschutzscheibe in den Fahrzeuginnenraum gelangt und dort sitzende Personen gefährdet. Um dieses Eindringen von Wild oder aber ganz allgemein: von Gegenständen bei einem Aufprall zu verhindern, befindet sich bevorzugt vor (aus der Sicht des Fahrers) der Innenseite der Windschutzscheibe 1 das netzartige Schutzgitter 2, das hier als Schutznetz, d. h. allseitig flexibel, ausgeführt ist. Das Schutzgitter 2 ist in seiner Betriebsstellung vor der Windschutzscheibe 1 gezeichnet; in seiner Ruhestellung, d. h. in crashfreien Zeiten, befindet sich das Schutzgitter 2 in dem Dachschalenschacht 3, d. h. innerhalb des eigentlichen Fahrzeugs. Aus dieser Ruhestellung ist das Schutzgitter 2 mit in diesem Ausführungsbeispiel zwei Zugantrieben 4 und 5 herausgezogen, die über Züge, z. B. Bowdenzüge 6 und 7, an einem unteren Randbereich des Schutzgitters 2 angreifen. Diese Zugantriebe 4 und 5 können nach Art von Sicherheitsgurtstrammern aufgebaut sein, beispielsweise als pyrotechnisch arbeitende Patronen, die über den Precrash- oder Crashsensor 8 bei Beginn eines Crashs, besser aber kurz zuvor gezündet werden und dann das Schutzgitter 2 in seine gezeichnete Betriebsstellung vor der Windschutzscheibe 1 bewegen.In a game accident, for example, the windshield 1 is exposed to the impact of an animal which is thrown up and which, after the windshield has been destroyed, enters the vehicle interior and endangers people sitting there. In order to prevent this intrusion of game or in general: objects in the event of an impact, the net-like protective grille 2 is preferably located in front of (from the driver's point of view) the inside of the windshield 1 , which is designed here as a protective net, ie flexible on all sides . The protective grille 2 is drawn in front of the windshield 1 in its operating position; In its rest position, ie in crash-free times, the protective grille 2 is located in the roof shell shaft 3 , ie inside the actual vehicle. From this rest position, the protective grille 2 is pulled out with two train drives 4 and 5 in this exemplary embodiment, which via trains, for. B. Bowden cables 6 and 7 , attack on a lower edge region of the protective grille 2 . These traction drives 4 and 5 can be constructed in the manner of seat belt tensioners, for example as pyrotechnically working cartridges, which are ignited via the pre-crash or crash sensor 8 at the beginning of a crash, but better before, and then the protective grille 2 in its drawn operating position in front of the windshield 1 move.

Mit der Erfindung ist demgemäß eine gattungsgemäße Schutzvorrichtung geschaffen, die mit minimalem Aufwand ohne Beeinträchtigung des Aussehens des Fahrzeugs einen wirksamen Schutz gegen das Eindringen von Tieren und Gegenständen durch die Windschutzscheibe bietet und darüber hinaus auch Bedeutung als Rückhalteelement für Fahrzeuginsassen hat.The invention accordingly provides a generic protective device, the one with minimal effort without affecting the appearance of the vehicle effective protection against the intrusion of animals and objects by the Windshield offers and also important as a retaining element for Has vehicle occupants.
