Abstract
Description
Die Erfindung betrifft eine Windschutzscheibe für ein Fahrzeug gemäß Oberbegriff des Patentanspruchs 1.The The invention relates to a windshield for a vehicle according to the preamble of claim 1
Windschutzscheiben dienen hauptsächlich dazu, die Insassen eines Fahrzeugs vor dem Fahrtwind zu schützen. Außerdem beeinflussen sie insbesondere die Aerodynamik und die Optik des Fahrzeugs und müssen daher entsprechend gestaltet sein. Schließlich wird durch die Windschutzscheibe, insbesondere bei Cabrio- und Roadsterfahrzeugen, der subjektive Fahreindruck bezüglich Windgeräuschen und Fahrtwindführung maßgeblich bestimmt. Insbesondere ein oberer Anströmbereich der Windschutzscheibe, über den der Fahrtwind zum Dach beziehungsweise zu der geöffneten Fahrgastzelle des Fahrzeugs hin geleitet wird, beeinflusst diesen Aspekt maßgeblich.Windshield serve mainly to to protect the occupants of a vehicle from the wind. In addition, influence They especially the aerodynamics and the optics of the vehicle and have to therefore be designed accordingly. Finally, through the windshield, in particular in convertible and roadster vehicles, the subjective driving impression in terms of wind noise and airflow guidance decisively certainly. In particular, an upper inflow region of the windshield, over the the wind to the roof or to the open passenger compartment of the vehicle directed, this aspect influences significantly.
Nachteilig ist, dass Optimierungen, insbesondere falls subjektive Kriterien wie beispielsweise die Beurteilung der Optik und das vermittelte Fahrgefühl eines Fahrzeugs eine gewichtige Rolle spielen, meist kompromissbehaftet sind.adversely is that optimizations, especially if subjective criteria such as the assessment of optics and the mediated driving experience a vehicle play a major role, usually compromised are.

Der Erfindung liegt die Aufgabe zugrunde, verschiedene Öffnungspositionen eines öffnungsfähigen Fahrzeugs mit geringem Aufwand zu ermöglichen.Of the Invention is based on the object, different opening positions an openable vehicle to allow with little effort.
Diese Aufgabe wird erfindungsgemäß durch eine Windschutzscheibe mit den Merkmalen des Anspruchs 1 gelöst.These The object is achieved by a Windshield solved with the features of claim 1.
Diese zeichnet sich dadurch aus, dass der obere Anströmbereich der Windschutzscheibe relativ zur Karosserie des Kraftfahrzeugs verstellbar ist. Es ist also möglich, den oberen Anströmbereich der Windschutzscheibe in seiner relativen Lage zum Rest des Fahrzeugs zu beeinflussen beziehungsweise zu verändern. Mithin ergeben sich auch hinsichtlich der Optimierung der Windschutzscheibe mehr Freiheiten, da diese durch die Einstellmöglichkeit ein Spektrum von jeweils anders subjektiv empfundenen Optima abdecken kann. Beispielsweise lässt sich so der Grundcharakter des Fahrzeugs von einem komfortablen Cabrio mit einer möglichst leisen und zugfreien Fahrtwindführung – auch bei geöffnetem Dach – hin zu einem Roadster verändern, bei dem gerade ein besonders zugiges Fahrgefühl mit freier Sicht auch nach vorne erwünscht ist. Weiter kann durch die Lageveränderung des oberen Anströmbereichs der Windschutzscheibe die Aerodynamik des Fahrzeugs beeinflusst werden. Denkbar ist insbesondere eine Anpassung zwischen geöffnetem und geschlossenem Zustand eines Cabrios, um jeweils den Luftwiderstand und damit den Spritverbrauch und die Fahrleistung zu optimieren. Öffnungsfähige Fahrzeuge weisen in der Regel je nach Öffnungszustand des Daches unterschiedliche Luftwiderstandsbeiwerte auf. Bereits eine geringe Lageveränderung des oberen Anströmbereichs kann beispielsweise den im geöffneten Zustand eines Fahrzeugs meist schlechteren Luftwiderstandsbeiwert positiv beeinflussen. Außerdem ist es denkbar, durch die Lageveränderung des oberen Anströmbereichs den insgesamt angeströmten Querschnitt des Fahrzeugs, insbesondere im geöffneten Zustand, zu verringern. Über die Lageveränderung des oberen Anströmbereichs können also für den Luftwiderstand eines Fahrzeugs maßgebliche Größen beeinflusst beziehungsweise abhängig vom Öffnungszustand optimiert werden.These is characterized in that the upper Anströmbereich the windshield is adjustable relative to the body of the motor vehicle. It is so possible, the upper inflow area the windshield in its relative position to the rest of the vehicle to influence or change. Consequently, arise also with regard to optimizing the windscreen more freedom, because of these through the adjustment cover a spectrum of differently subjectively perceived optima can. For example, let so the basic character of the vehicle from a comfortable Convertible with one possible Quiet and draft-free wind deflection - also at open Roof - down change to a roadster, in the just a particularly drafty driving feeling with a clear view even after desired in front is. Further, by the change in position of the upper Anströmbereichs the windshield affects the aerodynamics of the vehicle become. In particular, an adaptation between open is conceivable and closed state of a convertible to each air resistance and thus to optimize fuel consumption and driving performance. Openable vehicles have usually depending on the opening state of the roof on different drag coefficients. Already a slight change in position of the upper inflow region can, for example, in the open Condition of a vehicle usually worse drag coefficient influence positively. Furthermore it is conceivable, by the change in position of the upper Anströmbereichs the total streamed Cross-section of the vehicle, especially in the open state to reduce. About the change of position of the upper inflow region so can for the Air resistance of a vehicle influenced significant quantities or dependent from the opening state be optimized.
Besonders bevorzugt wird ein Ausführungsbeispiel der Erfindung, bei dem an dem Fahrzeug und/oder an der Windschutzscheibe elektrische und/oder mechanische Mittel zum Verlagern der gesamten Windschutzscheibe vorgesehen sind. Bei den Mitteln handelt es sich bevorzugt um übliche Scheibenantriebe, insbesondere um einen oder mehrere entsprechend dimensionierte Elektromotoren oder Getriebemotoren mit einer daran angepassten Abtriebsmechanik oder um durch Muskelkraft angetriebene Kurbel- und/oder Hebelantriebe. Dies ermöglicht eine komfortable Bedienung zur Verstellung des oberen Anströmbereichs beziehungsweise der gesamten Windschutzscheibe, gegebenenfalls auch während des Führens des Fahrzeugs.Especially preferred is an embodiment the invention, wherein on the vehicle and / or on the windshield electrical and / or mechanical means for relocating the entire Windshield are provided. The funds are preferred to conventional disk drives, in particular one or more correspondingly dimensioned electric motors or Geared motors with an adapted output mechanism or by muscle-powered crank and / or lever drives. this makes possible a comfortable operation to adjust the upper Anströmbereichs or the entire windscreen, possibly also during the passing of the vehicle.
Weitere Ausführungsbeispiele ergeben sich aus den Kombinationsmöglichkeiten der übrigen Unteransprüche, aus der Beschreibung und der dazugehörigen Zeichnung.Further embodiments arise from the combination options of the other dependent claims, from the description and the associated Drawing.
