Description

Luftleitkanal vor der Dachöffnung an einem Kraftfahrzeug, insbesondere Personenwagen Die Erfindung betrifft ein Kraftfahrzeug, insbesondere Personenwagen, mit einem geschlossenen Aufbau, dessen Dach ganz oder teilweise geöffnet werden kann, und mit einem Leitkanal, der der Luft eine die Dachöffnung überspringende Strömung erteilt. Bei bekannten Kraftwagen dieser Art ist zur Bildung des Leitkanals für die Luft eine schmale Leitfläche über der Vorderkante des Daches beweglich angeordnet. Diese Leitfläche erfordert eine umständliche Verstelleinrichtung, die die Anordnung des Leitkanals verteuert. Außerdem büßt der Leitkanal bei der bekannten Anordnung einen wesentlichen Teil seiner Wirkung dadurch ein, daß seine Ausblasmündung nicht unmittelbar vor der Dachöffnung liegt.Air duct in front of the roof opening on a motor vehicle, in particular Passenger car The invention relates to a motor vehicle, in particular a passenger car, with a closed structure, the roof of which can be opened completely or partially can, and with a duct that allows the air to jump over an opening in the roof Current granted. In known motor vehicles of this type is to form the guide channel for the air, a narrow guide surface is movably arranged above the front edge of the roof. This guide surface requires a cumbersome adjustment device, which the arrangement of the guide channel increases in price. In addition, the guide channel loses in the known arrangement a substantial part of its effect by the fact that its blow-out does not lies directly in front of the roof opening.

Der Erfindung liegt die Aufgabe zugrunde, diese bei bekannten Ausführungen bestehenden Mängel zu beseitigen und bei konstruktiv einfachem Aufbau gleichzeitig eine wirkungsvolle und befriedigende Luftführung zu erzielen.The invention is based on the object of this in known designs to eliminate existing defects and at the same time with a structurally simple structure to achieve an effective and satisfactory air flow.

Diese Aufgabe wird mit der Erfindung dadurch gelöst, daß der an die Windschutzscheibe angrenzende, feststehende vordere Dachteil als Luftleitkanal ausgebildet ist, dessen Ausblasmündung unmittelbar vor der Dachöffnung liegt.This object is achieved with the invention in that the to The fixed front roof part adjacent to the windshield is designed as an air duct is, the outlet of which is immediately in front of the roof opening.

Die Erfindung hat den Vorteil, daß die Anbringung des Luftleitkanals keine wesentlichen Mehrkosten erfordert und der Fahrwind bei geöffnetem Dach und jeder Größe der Dachöffnung zuverlässig über diese Öffnung hinweggeleitet wird und keine lästigen Wirbel im Innern des Wagenaufbaues erzeugt.The invention has the advantage that the attachment of the air duct requires no significant additional costs and the wind with the roof open and any size of the roof opening is reliably passed over this opening and no annoying eddies generated inside the car body.

Um die ablenkende Wirkung des Leitkanals auf den Fahrwind zu erhöhen, kann die Ausblasmündung des Leitkanals vorteilhaft so gestaltet sein, daß die Richtung der aus dem Kanal ausströmenden Luft die der umströmenden Luft schneidet. Damit der Fahrwind nur bei geöffnetem Dach durch den Leitkanal strömt, kann die Ausblasmündung desselben zweckmäßig durch den beweglichen Teil des Daches verschließbar sein. Schließlich kann in dem Leitkanal in vorteilhafter Weise dadurch eine Stauwirkung erzielt werden, daß der Querschnitt des Leitkanals nach der Ausblasmündung zu abnimmt.To increase the distracting effect of the guide channel on the driving wind, the blow-out opening of the guide channel can advantageously be designed so that the direction the air flowing out of the duct intersects the air flowing around it. In order to the airflow can only flow through the duct when the roof is open the same can be expediently closed by the movable part of the roof. In the end a damming effect can thereby advantageously be achieved in the guide channel, that the cross-section of the guide channel decreases after the blow-out port.

Die Zeichnung veranschaulicht die Erfindung beispielsweise an zwei schematisch dargestellten Ausführungsformen des Gegenstandes derselben, und zwar zeigt Fig. 1 einen Längsschnitt durch den vorderen Teil des Wagenaufbaues eines Personenkraftwagens bekanuter Ausführung mit Schiebedach, Fig.2 den gleichen Längsschnitt bei einem erfindungsgemäß ausgebildeten Kraftwagen und Fig.3 eine weitere Ausführungsform des Erfindungsgegenstandes, ebenfalls in einem Längsschnitt. Wie aus Fig. 1 ersichtlich ist, trifft der Fahrwind auf die Windschutzscheibe 1 des Wagenaufbaues auf und strömt dann um den vorderen feststehenden Teil 2 des Wagenaufbaues. Bei geöffneten Schiebedach 3 strömt der Fahrwind durch die Öffnung in das Innere des Wagenaufbaues ein und erzeugt hier starke Wirbel, die sich unangenehm bemerkbar machen.The drawing illustrates the invention in two examples schematically illustrated embodiments of the subject matter of the same, namely Fig. 1 shows a longitudinal section through the front part of the car body of a Passenger car well-known version with sliding roof, Figure 2 the same longitudinal section in a motor vehicle designed according to the invention and FIG. 3 shows a further embodiment of the subject matter of the invention, also in a longitudinal section. As can be seen from FIG is, the driving wind hits the windshield 1 of the car body and flows then around the front fixed part 2 of the car body. With the sunroof open 3 the driving wind flows through the opening into the interior of the car body and creates strong eddies here, which are uncomfortably noticeable.

Gemäß der Erfindung ist der feststehende vordere Dachteil 2 als Leitkanal 4 ausgebildet, der sich über die gesamte Breite des Daches erstreckt und so gestaltet ist, daß sein Querschnitt sich nach der Ausblasmündung 5 zu etwas verringert. Durch diesen Kanal 4 wird die an der Windschutzscheibe 1 abströmende Luft erfaßt und durch den Staudruck über die Öffnung des Daches geleitet.According to the invention, the fixed front roof part 2 is used as a guide channel 4 formed, which extends over the entire width of the roof and designed so is that its cross-section decreases to something after the blow-out port 5. By the air flowing off the windshield 1 is detected and passed through this channel 4 the dynamic pressure passed through the opening in the roof.

Bei der in Fig.3 dargestellten Ausführungsform des Erfindungsgegenstandes ist der Leitkanal 4 so gestaltet, daß seine Ausblasmündung 5 schräg nach oben gerichtet ist. Damit diese Mündung 5 bei geschlossenem Dach durch das Schiebedach 3 verschlossen wird, ist an diesem eine vorstehende Abschlußleiste 6 angebracht.In the embodiment of the subject matter of the invention shown in FIG the guide channel 4 is designed so that its blow-out opening 5 is directed obliquely upwards is. So that this mouth 5 is closed by the sliding roof 3 when the roof is closed is, a protruding end strip 6 is attached to this.
