Windabweiser für ein Fahrzeugdach mit beweglichem DachteilWind deflector for a vehicle roof with a movable roof part
Die Erfindung betrifft einen Windabweiser für eine mittels eines beweglichen Dachteils verschließbare und wenigstens teilweise freigebbare Dachöffnung in einem Fahrzeug mit einem zwischen einem in einem Dachoffnungsrahmen integrierbaren, bügeiförmigen Basiselement und einem darüber angeordneten bügeiförmigen Ausstellelement aufspannbaren Netz, wobei das Ausstellelement mittels mindestens einer in seitlichen Bügelendbereichen des bügeiförmigen Ausstellelements angeordneten Kurvenbahn ausstellbar ist, gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a wind deflector for a roof opening in a vehicle that can be closed and at least partially released by means of a movable roof part, with a net-shaped base element that can be stretched out between a bow-shaped base element that can be integrated in a roof opening frame and a bow-shaped deployment element arranged above it, the deployment element using at least one in side temple end areas of the Bow-shaped display element arranged cam track is deployable, according to the preamble of claim 1.
Windabweiser mit einem bügeiförmigen Basiselement und einem darüber ange- ordneten bügeiförmigen Ausstellelement, zwischen welchen ein Netz aufspannbar ist, sind aus DE 102 10 142 A1 bekannt. Derartige Netzwindabweiser sind herkömmlicherweise in nicht wasserführenden Bereichen des Dachöffnungsrahmens untergebracht, um ein Einfrieren des Netzes im Winter und ein Verschmutzen desselbigen durch Regenwasser oder dergleichen zu vermeiden. Bei dem nicht wasserführenden Bereichen handelt es sich um denjenigen Anteil des Dachöff- nungsrahmens, der zu der Dachöffnung hin - also bei einer Draufsicht auf den Dachoffnungsrahmen innenliegend - angeordnet ist.Wind deflectors with a bow-shaped base element and a bow-shaped deployment element arranged above them, between which a net can be stretched, are known from DE 102 10 142 A1. Such net wind deflectors are conventionally housed in non-water-bearing areas of the roof opening frame in order to avoid freezing the net in winter and soiling it by rain water or the like. The non-water-carrying areas are the parts of the roof opening frame that are arranged towards the roof opening - that is, when the roof opening frame is viewed from the inside.
Solche Windabweiser zeichnen sich dadurch aus, dass sie insbesondere in Dach- Öffnungen mit sich nach außen öffnenden Schiebedeckeln oder so genannten Spoilerdächern aufgrund der anfänglich stattfindenden Nachobenbewegung des Schiebedeckels während des Öffnungsvorganges vorteilhaft angeordnet werden können. Zeitgleich mit der Nachobenbewegung des Schiebedeckels stellt sich ein derartiger Windabweiser zur Unterdrückung von in einen Fahrgastinnenraum einströmender Zugluft ansatzweise auf.Such wind deflectors are characterized in that they are advantageously arranged in roof openings with outwardly opening sliding lids or so-called spoiler roofs due to the initial upward movement of the sliding lid during the opening process can. Simultaneously with the upward movement of the sliding cover, such a wind deflector for the suppression of drafts flowing into a passenger interior is beginning to set up.
Häufig werden solche Windabweiser mittels eines in seitlichen Endbereichen des bügeiförmigen Ausstellelementes und am Dachoffnungsrahmen angebrachten aktiven Steuerungsmechanismus mit Hilfe einer vorgegebenen Kurvenbahn selbsttätig und zeitgleich mit der Öffnungsbewegung des Schiebedeckels bewegt. Während des Öffnungsvorganges findet nach der anfänglichen Nachobenbewe- gung und der nach vorne gerichteten leichten Schwenkbewegung des Deckels ein Nachhintenverschieben des Schiebedeckels entlang einer relativ langen Wegstrecke der seitlichen Bereiche des bügeiförmigen Windabweisers statt. Das Ausstellelement kann erst dann vollständig ausgestellt werden beziehungsweise vollständig nach oben verschwenkt werden, wenn es von einer fahrzeugvorderseitigen Kante des Schiebedeckels während des Öffnungsvorganges überfahren wurde. Dieser Steuerungsmechanismus hat zur Folge, dass während dieses Öffnungsvorganges ein spaltartiger Zwischenraum zwischen der Unterseite des Schiebedeckels und einem in Fahrzeugquerrichtung verlaufenden Teil des Windabweisers, der eine Spaltbreite von ca. 5 mm aufweist, entsteht. Hierdurch werden wei- terhin unerwünschte Windgeräusche und Zugluft im Fahrzeuginnenraum verursacht.Frequently, such wind deflectors are moved automatically and simultaneously with the opening movement of the sliding cover by means of an active control mechanism attached in the lateral end regions of the bow-shaped opening element and on the roof opening frame with the aid of a predetermined curved path. During the opening process, after the initial upward movement and the forward, slight pivoting movement of the cover, the sliding cover is moved backwards along a relatively long distance of the lateral areas of the bow-shaped wind deflector. The opening element can only be completely exhibited or swiveled completely upwards when it has been run over by an edge of the sliding cover on the front of the vehicle during the opening process. The consequence of this control mechanism is that a gap-like space is created between the underside of the sliding cover and a part of the wind deflector which runs in the transverse direction of the vehicle and has a gap width of approximately 5 mm during this opening process. This continues to cause unwanted wind noise and drafts inside the vehicle.
Demzufolge liegt der vorliegenden Erfindung die Aufgabe zugrunde, einen Windabweiser mit einem aktiven Steuerungsmechanismus zum Ausstellen des Wind- abweisers für ein Fahrzeugdach mit beweglichen Dach zur Verfügung zu stellen, bei dem unerwünschte Windgeräusche und Zugluft während des Öffnungs- und Schließvorganges des Fahrzeugdaches vermieden werden.Accordingly, the object of the present invention is to provide a wind deflector with an active control mechanism for opening the wind deflector for a vehicle roof with a movable roof, in which undesirable wind noise and drafts are avoided during the opening and closing process of the vehicle roof.
Diese Aufgabe wird gemäß den Merkmalen des Patentanspruches 1 gelöst. Ein wesentlicher Punkt der Erfindung liegt darin, dass bei einem Windabweiser für ein mittels eines beweglichen Dachteils verschließbare und wenigstens teilweise freigebbare Dachöffnung in einem Fahrzeugdach mit einem zwischen einem in einem Dachoffnungsrahmen integrierbaren bügeiförmigen Basiselement und ei- nem darüber angeordneten bügeiförmigen Ausstellelement aufspannbaren Netz und mit einem aktiven Steuermechanismus in seitlichen Bügelendbereichen des Ausstellelementes zusätzlich ein linienförmiges, flexibles Element zur Abdichtung eines während des Öffnungs- und/oder Schließvorganges des Dachteils bestehenden spaltartigen Zwischenraumes zwischen einer Unterseite des Dachteils und dem Ausstellelement auf diesem angeordnet ist. Dieses linienförmige flexible Element ist an einer Oberseite des Ausstellelementes, vorzugsweise im Fahrzeugquerrichtung verlaufenden Bereich des Ausstellelementes angeordnet. Auf diese Weise wird vorteilhaft eine bezüglich der einströmenden Zugluft und der Windgeräusche wirkungsvolle Abdichtung zwischen Windabweiser und dem Dachteil, der als Schiebedeckel ausgebildet sein kann, erhalten.This object is achieved according to the features of patent claim 1. An essential point of the invention is that in the case of a wind deflector for a roof opening in a vehicle roof that can be closed and at least partially released by means of a movable roof part, it has a net that can be stretched between a bow-shaped base element that can be integrated in a roof opening frame and a bow-shaped deployment element arranged above it active control mechanism in the lateral temple end areas of the display element, a linear, flexible element for sealing an existing gap-like gap between the underside of the roof part and the display element during the opening and / or closing process of the roof part is arranged thereon. This linear flexible element is arranged on an upper side of the display element, preferably in the region of the display element running in the transverse direction of the vehicle. In this way, an effective seal with respect to the inflowing drafts and the wind noise is obtained between the wind deflector and the roof part, which can be designed as a sliding cover.
Da das Ausstellelement mittels mindestens einer in seitlichen Bügelendbereichen des bügeiförmigen Ausstellelementes angeordneten Kurvenbahn selbsttätig und zeitgleich mit dem Verschieben des Schiebedeckels ausstellbar ist, kann während eines öffnungs- oder Schließvorganges des Schiebedeckels ein gleichmäßiger Druck auf die Unterseite des Schiebedeckels durch das linienförmige flexible Element derart ausgeübt werden, dass der Druck auf der einen Seite hoch genug ist, um eine zufrieden stellende Abdichtung zwischen dem Ausstellelement und der Unterseite des Schiebedeckels zu erhalten und auf der anderen Seite gering ge- nug ist, um störende Gleitgeräusche während des Verschiebens des Schiebedeckels in Fahrzeuglängsrichtung zu vermeiden.Since the opening element can be turned out automatically and at the same time as the sliding cover is being moved by means of at least one cam track arranged in the lateral end portions of the bow-shaped opening element, uniform pressure can be exerted on the underside of the sliding cover by the linear flexible element during an opening or closing operation of the sliding cover that the pressure on one side is high enough to maintain a satisfactory seal between the display element and the underside of the sliding cover and on the other hand is low enough to avoid annoying sliding noises when the sliding cover is moved in the longitudinal direction of the vehicle ,
Fahrzeugdächer von Kraftfahrzeugen weisen häufig eine in Fahrzeugquerrichtung verlaufende Wölbung auf, die eine entsprechende Wölbung des Windabweisers im in Richtung der Fahrzeugquerrichtung verlaufenden Anteil erfordert. Aufgrund die- ser gewölbten Ausbildung des Windabweisers in seinem vorderen Teil, der sich nach einem Nachhintenschieben des Deckels vor einer vorderseitigen Kante des Deckels aufstellt, ist zwingend ein aktiver Steuerungsmechanismus erforderlich, der den Abstand zwischen der Oberseite des Windabweisers und der Unterseite des Schiebedeckels während des Öffnungs- und Schließungsvorganges regelt. Der Steuerungsvorgang des aktiven Steuerungsmechanismuses kann nun mittels des Erfindungsgegenstandes vorteilhaft diesen Abstand derart regeln, dass einerseits kein Geräusch und Schleifspuren erzeugendes Anliegen des flexiblen Elementes an der Unterseite des Schiebedeckels und andererseits eine wind- und geräuschabdichtende Wirkung erreicht wird. Hinzu kommt, dass bei einer anfänglichen Schwenkbewegung des Schiebedeckels während des Öffnungsvorganges derart, dass der Schiebedeckel in seinem hinteren Bereich mehr als in seinem vorderen Bereich nach oben ausgefahren wird, ein nahezu reibungsloses Entlanggleiten der Schiebedeckelunterseite auf dem flexiblen Element während die- ser Schwenkbewegung ermöglicht wird.Vehicle roofs of motor vehicles often have a curvature running in the vehicle transverse direction, which requires a corresponding curvature of the wind deflector in the portion running in the direction of the vehicle transverse direction. Because of this ser arched design of the wind deflector in its front part, which stands up after pushing the cover back in front of a front edge of the cover, an active control mechanism is imperative that the distance between the top of the wind deflector and the underside of the sliding cover during opening and Closing process regulates. The control process of the active control mechanism can now advantageously regulate this distance by means of the subject matter of the invention in such a way that, on the one hand, the flexible element on the underside of the sliding cover does not produce any sound and grinding marks, and on the other hand a wind and noise-sealing effect is achieved. In addition, during an initial swiveling movement of the sliding cover during the opening process in such a way that the sliding cover is extended more upwards in its rear area than in its front area, an almost smooth sliding of the underside of the sliding cover on the flexible element is made possible during this swiveling movement ,
Gemäß einer bevorzugten Ausführungsform kann das linienförmige, flexible Element als Hohlkammerdichtelement ausgebildet sein. Alternativ kann ein weichelastisches Vollmaterial, beispielsweise aus Gummi oder gummiartigen Stoffen, verwendet werden.According to a preferred embodiment, the linear, flexible element can be designed as a hollow chamber sealing element. Alternatively, a soft elastic solid material, for example made of rubber or rubber-like materials, can be used.
Das flexible Element kann zudem als elastisches Material lippenartig ausgebildet sein, sodass durch ein selbsttätiges sichaufstellen einer Lippe eine zuverlässige Abdichtung zur Unterseite des Schiebedeckels erfolgt.The flexible element can also be lip-shaped as an elastic material, so that an automatic opening of a lip provides a reliable seal to the underside of the sliding cover.
Stattdessen oder zusätzlich kann das linienförmige, flexible Element als schwenkbares klappenartiges Element, wahlweise mit Federbeaufschlagung ausgebildet sein.Instead, or in addition, the linear, flexible element can be designed as a pivotable flap-like element, optionally with spring loading.

In Fig. 1 ist in einer seitlichen Querschnittsansicht ausschnittsweise ein Fahrzeugdach mit einem Windabweiser gemäß dem Stand der Technik dargestellt. Das Fahrzeugdach 1 weist eine Dachöffnung 2 auf, die mittels eines Schiebedeckels 3, der als Glasdeckel ausgebildet sein kann, verschließbar und freigebbar ist. Sofern sich der Schiebedeckel 3 im geschlossenen Zustand befindet, dienen dachöff- nungsvorderseitig angebrachte Dichtelemente 4 und 5 zur Abdichtung eines vorderen Randbereiches der Dachöffnung 2. Das Dichtelement 5 kann an einem Dachoffnungsrahmen oder Karosserieteil 6 befestigt sein.1 shows a partial cross-sectional view of a vehicle roof with a wind deflector according to the prior art. The vehicle roof 1 has a roof opening 2, which can be closed and released by means of a sliding cover 3, which can be designed as a glass cover. If the sliding cover 3 is in the closed state, sealing elements 4 and 5 attached to the front of the roof opening serve to seal a front edge area of the roof opening 2. The sealing element 5 can be fastened to a roof opening frame or body part 6.
Ein ausschnittsweise dargestellter bügeiförmiger Windabweiser 7, der sich in die- sem Fall in Fahrzeugquerrichtung erstreckt, ist unterhalb einer Unterseite 3a des Schiebedeckels 3 angeordnet und bildet während des hier dargestellten öffnungs- Vorganges des Schiebedeckels im Zusammenspiel mit der Unterseite 3a des Schiebedeckels einen spaltartigen Zwischenraum 8, der sich nachteilhaft auf Windgeräusche und Zugluft im Fahrzeuginnenraum auswirkt.A section-shaped bow-shaped wind deflector 7, which in this case extends in the transverse direction of the vehicle, is arranged below an underside 3a of the sliding cover 3 and forms during the opening shown here. Operation of the sliding cover in interaction with the underside 3a of the sliding cover creates a gap-like space 8, which has a disadvantageous effect on wind noise and drafts in the vehicle interior.
In Fig. 2 wird in einer schematischen seitlichen Querschnittsansicht ein Ausschnitt eines Fahrzeugdaches mit einem Windabweiser gemäß einer Ausführungsform der Erfindung gezeigt. Gleiche und gleichwirkende Bauteile sind mit gleichen Bezugszeichen wie in Figur 1 versehen.2 shows a schematic lateral cross-sectional view of a section of a vehicle roof with a wind deflector according to an embodiment of the invention. The same and equivalent components are provided with the same reference numerals as in Figure 1.
Der Schiebedeckel 3 liegt mit seiner Unterseite 3a in dem hier dargestellten geschlossenen Zustand des Fahrzeugdaches an einem abdichtenden Element 9 an, welches auf einer Oberseite eines Ausstellarmes 7 eines Windabweisers angeordnet ist. Der Darstellung ist deutlich zu entnehmen, dass bereits im geschlossenen Zustand aufgrund der Anordnung des flexiblen Elementes 9, welches als Hohlkammerdichtelement ausgebildet ist, kein Spalt zwischen der Unterseite 3a des Deckels 3 und dem Ausstellelement 7 besteht.The sliding cover 3 lies with its underside 3a in the closed state of the vehicle roof shown here against a sealing element 9 which is arranged on an upper side of a deployment arm 7 of a wind deflector. The illustration clearly shows that even in the closed state, due to the arrangement of the flexible element 9, which is designed as a hollow chamber sealing element, there is no gap between the underside 3a of the cover 3 and the opening element 7.
In Fig. 3 ist in einer schematischen seitlichen Querschnittsansicht ein Ausschnitt des in Fig. 2 dargestellten Fahrzeugdaches mit dem Windabweiser gemäß der Ausführungsform dargestellt, wobei die in Fig. 3 wiedergegebene Darstellung das Fahrzeugdach in teilweise geöffneten Zustand zeigt. Dieser Darstellung ist deutlich zu entnehmen, dass selbst während eines Öffnungsvorganges des Schiebedeckels 3, während dem sich der Schiebedeckel 3 zunächst nach oben und anschließend nach hinten - in Bildebene gesehen nach rechts - bewegt, eine zuver- lässige Abdichtung gegenüber Zugluft und Windgeräuschen zwischen der Unterseite 3a des Schiebedeckels 3 und dem Hohlkammerdichtelement 9 vorhanden ist.FIG. 3 shows a schematic cross-sectional side view of a section of the vehicle roof shown in FIG. 2 with the wind deflector according to the embodiment, the illustration shown in FIG. 3 showing the vehicle roof in a partially opened state. This illustration clearly shows that even during an opening process of the sliding cover 3, during which the sliding cover 3 first moves upwards and then backwards - as seen to the right in the image plane - there is a reliable seal against drafts and wind noise between the underside 3a of the sliding cover 3 and the hollow chamber sealing element 9 is present.
In Fig. 4 wird in einer perspektivischen Darstellung ein Ausschnitt des Windabwei- sers gemäß der Ausführungsform der Erfindung mit dem Schiebedeckel 3 dargestellt. Der Windabweiser weist zwischen seinem ausstellbaren Ausstellelement 7 und einem ebenso bügeiförmig ausgebildeten Basiselement 10, welches mit einem Dachoffnungsrahmen 13 verbunden ist, ein aufspannbares Netz 11 auf, das sich bei Absenken des Ausstellelementes 7 zusammenfaltet.4 shows a perspective view of a section of the wind deflector according to the embodiment of the invention with the sliding cover 3. The wind deflector has between its deployable opening element 7 and an equally bow-shaped base element 10, which is connected to a roof opening frame 13, a stretchable net 11, which folds when the opening element 7 is lowered.
Das Ausstellelement 7 wird mittels eines aktiven Steuerungsmechanismus, dessen Funktion durch eine in Endbereichen 7a des Ausstellarmes 7 angeordneten Kurvenbahn 12 bestimmt und in seinem Bewegungsablauf vorgegeben ist, ausgestellt. Durch eine entsprechende Ausbildung dieser Kurvenbahn 12 kann ein gleichmäßiger Druck des Hohlkammerdichtelement.es 9 auf die Unterseite 3a des Schiebedeckels 3 während dessen Öffnungs- und/oder Schließablaufes ausgeübt werden, ohne dass hierdurch störende Gleitgeräusche aufgrund von Reibung oder dergleichen entstehen.The deployment element 7 is issued by means of an active control mechanism, the function of which is determined by a curved path 12 arranged in end regions 7a of the deployment arm 7 and is predetermined in its movement sequence. By appropriately designing this curved path 12, a uniform pressure of the hollow chamber sealing element 9 can be exerted on the underside 3a of the sliding cover 3 during its opening and / or closing sequence, without this causing disturbing sliding noises due to friction or the like.
