Abstract

The spherical contoured window for a vehicle door is operated by two cable drives in guide rails. The guide rail corresponding to the more curved part of the window is inclined w.r.t. the drive plane. The amount of tilts is such that the sliders in both guide rails cover the same distances along the tracks but with different actual movements of the window. For steeply inclined guide rails the slider grips the glass via a sliding compensating rail. The inclined rail can be replaced by a curved rail (1A). The cable drives are linked and can each be driven by an electric servo motor.

Description

Die Erfindung betrifft einen Seilfensterheber für Kraftfahrzeuge gemäß dem Oberbegriff des Patentanspruchs 1. Der Fensterheber ist besonders ausgebildet zur Führung von sphärisch gekrümmten Fensterscheiben eines Kraftfahrzeugs und gewährleistet bei stark unterschiedlichen Krümmungsradien der Fensterscheibe an den Stellen der beiden Führungsschienen, die exakte Einhaltung einer vorgegebenen Abzugsbahn. The invention relates to a cable window lifter for motor vehicles according to the preamble of claim 1. The Window regulator is specially designed to guide spherically curved window panes of a motor vehicle and ensures with very different radii of curvature the window pane at the locations of the two guide rails, the exact adherence to a given withdrawal path.

Es ist üblich, sphärisch gekrümmte Fensterscheiben in Kraftfahrzeugen mit Armfensterhebern zu betätigen, wobei die Fensterscheiben in seitlichen Führungen der Fahrzeugtür, die bis nahe an den Türboden reichen, gleiten. Diese seitlichen Führungen sind notwendig, um die senkrecht zur Scheibenebene auftretenden Kräfte ableiten zu können. Von Nachteil ist jedoch, daß die eine seitliche Führung im Schloßbereich oft zu Platzproblemen führt, insbesondere wenn die Türkonstruktion besonders schmal ausgebildet ist. Deshalb wird erforderlichenfalls ein Teil der seitlichen Führung als separates Zuatzteil ausgeführt und nach der Schloßmontage eingesetzt. Somit muß ein erhöhter Montageaufwand in Kauf genommen werden.It is common to have spherically curved window panes in To operate motor vehicles with arm windows, where the window panes in the side guides of the vehicle door, that reach close to the door floor slide. This lateral guides are necessary to make the perpendicular to the To be able to derive the plane occurring forces. Of The disadvantage, however, is that the lateral guidance in Lock area often leads to space problems, especially if the door construction is particularly narrow. Therefore, if necessary, part of the side Run as a separate additional part and after the Lock assembly used. Thus, an increased assembly effort to be accepted.

Die Verwendung einsträngiger Seilfensterheber erscheint oftmals wenig vorteilhaft zum Heben und Senken großer, sphärisch ausgebildeter Fensterscheiben, weil ein Verkippen der Fensterscheibe wegen der nicht ausreichend vorhandenen Mitnehmerbasis meistens nicht vermieden werden kann.The use of single-strand cable window lifters appears often not very advantageous for lifting and lowering large, spherically formed window panes because of a tilting the window pane due to the insufficient availability Driver base mostly can not be avoided.

Die Anwendung bekannter konventioneller doppelsträngiger Seilfensterheber ist zwar geeignet, die Fensterscheibe in der sogenannten Y-Richtung (quer zur Scheibenebene) sicher zu führen und ein Verkippen der Fensterscheibe zu vermeiden, jedoch entspricht der typische parallele Abzug nicht den Erfordernissen der unterschiedlichen Abzugslängen an den Stellen der jeweiligen Führungsschienen. Deshalb kippt die Fensterscheibe zwangsläufig aus ihrer vorgesehenen Abzugsbahn heraus, was auch zu einem Verklemmen führen kann. The use of known conventional double-stranded Cable winch is suitable, the window in the so-called Y direction (across the disc plane) and to prevent the window pane from tilting, however, the typical parallel deduction does not match the requirements of the different trigger lengths the positions of the respective guide rails. Therefore tilts the window pane inevitably out of its intended Trigger path out, which also lead to jamming can.

Aus der EP-A-0 064 135 ist ein gattungsgemäßer Scheibenheber für eine sphärisch gekrümmte Scheibe bekannt, deren in Fahrtrichtung vorderer und hinterer Bereich mit unterschiedlichen Geschwindigkeiten auf- und abwärts bewegbar ist. Dies wird in einer ersten Ausführungsform mit einem Scheibenhebemechanismus erzielt, der dem vorderen und hinteren Bereich der Scheibe zugeordnete, karosseriefeste Zahnstangen umfaßt, die mit zwei mit der Scheibe verbundenen und gleichzeitig antreibbaren Ritzeln mit unterschiedlichen Teilkreisdurchmessern kämmen. Dadurch werden unterschiedlich lange Abwicklungen der Scheibe in diesem Bereich kompensiert und ein verkantungsfreier Bewegungsablauf der Scheibe erzielt.From EP-A-0 064 135 is a generic window lifter known for a spherically curved disc, the front and rear area with different in the direction of travel Movable speeds up and down is. In a first embodiment, this is done with a Mechanism achieved by the front and assigned to the rear area of the window, fixed to the body Includes racks with two connected to the disc and at the same time driven pinions with different Comb pitch circle diameters. This will be different long windings in this area compensated and a tilt-free movement of the Disc achieved.

In einem Ausführungsbeispiel dieses Dokuments wird die Scheibe in dem Türkörper mittels eines Seilzuges in vertikaler Richtung bewegt, wozu am Türkörper vier Umlenkrollen gelagert sind, um die ein von einer Antriebsvorrichtung angetriebenes Seil gelegt ist. Während die dem hinteren Bereich der Scheibe zugeordneten Umlenkrollen in Bewegungsrichtung übereinander angeordnet sind, stehen die dem vorderen Bereich der Scheibe zugeordneten Umlenkrollen in einem Winkel zur Bewegungsrichtung der Scheibe. Dadurch wird eine geringere Geschwindigkeit in Bewegungsrichtung der Scheibe durch eine längere Abwicklung der Scheibe in ihrem vorderen Bereich ausgeglichen und dadurch die Scheibe ohne Verkanten geführt.In one embodiment of this document, the Washer in the door body by means of a cable in vertical Moved in the direction of which four deflection rollers on the door body are stored around the one of a drive device driven rope is laid. While the rear Area of the pulley assigned pulleys in the direction of movement are arranged one above the other in the front area of the pulley assigned an angle to the direction of movement of the disk. Thereby becomes a slower speed in the direction of movement the disc through a longer development of the disc in balanced their front area and thereby the disc performed without tilting.

Zum Ausgleich des in Bezug auf die Bewegungsrichtung der Scheibe im Winkel verlaufenden Seilzugabschnittes zwischen den dem vorderen Bereich der Scheibe zugeordneten Umlenkrollen ist an einer mit der Scheibe verbundenen Konsole eine Kulissenführung mit einem Langloch angeformt, in dem ein am Seil befestigter Mitnehmer verschiebbar geführt ist. Der dem hinteren Bereich der Scheibe zugeordnete Mitnehmer wirkt dagegen unmittelbar auf die Konsole und damit auf die Scheibe.To compensate for the movement direction of the Washer at an angle between the cable section the pulleys assigned to the front area of the disc is on a console connected to the disc Link guide molded with an elongated hole in which a Rope attached carrier is slidably guided. The drivers assigned to the rear area of the pane on the other hand acts directly on the console and thus on the Disc.

Bei dem bekannten Fensterheber sind die Fensterscheibenführungen und die Angriffspunkte des Fensterscheibenantriebs voneinander getrennt, so daß eine große Teilezahl erforderlich ist und der Scheibenhebemechanismus erst am Ort der Verbindung mit der Kraftfahrzeugtür und der Fensterscheibe funktionsfähig und in seiner Funktion überprüfbar ist.In the known window regulator are the window pane guides and the targets of the window pane drive separated from each other so that a large number of parts is required is and the window lifting mechanism only at the location of the Connection with the motor vehicle door and the window pane is functional and its function can be checked.

Aus der DE-C1 36 15 578 ist ein gattungsgemäßer Seilfensterheber bekannt, der eine Kombination von zwei einsträngigen Seilfensterhebern darstellt, wobei jede der beiden geschlossenen Seilschlaufen über eine separate Seiltrommel geführt ist. Ein gemeinsames Antriebsrad überträgt die Antriebskraft auf die beiden Seiltrommeln. Bezweckt wird mit dieser Konstruktion, Seilwechselbiegung zu vermeiden und so die Haltbarkeit des Seils zu verbessern.From DE-C1 36 15 578 is a generic cable window lifter known of a combination of two single-stranded Rope window lifters, each of the two closed Rope loops run over a separate rope drum is. A common drive wheel transmits the driving force on the two rope drums. The purpose is with this Construction to avoid rope change bends and so the Improve the durability of the rope.

Der Erfindung liegt die Aufgabe zugrunde, einen Seilfensterheber für Kraftfahrzeuge zu entwickeln, der unter Anwendung eines einfachen und kostengünstigen konstruktiven Aufbaus einen exakten Abzug einer sphärisch gekrümmten Fensterscheibe auf einer vorgesehenen Abzugsbahn gewährleistet, einen geringen Platzbedarf aufweist und eine gute Zugänglichkeit im Schloßbereich ermöglicht.The invention has for its object a cable window lifter to develop for motor vehicles using a simple and inexpensive construction an exact deduction of a spherically curved window pane guaranteed on a designated runway, one has a small footprint and good accessibility enabled in the castle area.

Erfindungsgemäß wird die Aufgabe durch einen Seilfensterheber mit den Merkmalen des unabhängigen Anspruchs 1 gelöst. According to the invention, the task is performed by a cable window lifter solved with the features of independent claim 1.

Demgemäss besteht die Möglichkeit zur Verschiebung einer Fensterscheibe an zwei Führungsschienen mit unterschiedlicher Hubcharakteristik durch die Verwendung von zwei separaten, entlang der Führungsschiene gespannten Seilen, denen jeweils separate elektromotorische Antriebe zugeordnet sind. Die elektronischen Antriebe werden von einer gemeinsamen elektronischen Steuereinheit angesteuert. Somit kann, insbesondere bei Verwendung einer sogenannten Positionserkennung der Fensterscheibe, diese in den gewünschten unterschiedlichen Hubverhältnissen verfahren werden.Accordingly, there is the possibility of moving one Window pane on two guide rails with different ones Stroke characteristics through the use of two separate, ropes tensioned along the guide rail, to which each assigned separate electric motor drives are. The electronic drives are shared by one controlled electronic control unit. So, especially when using a so-called position detection the window pane, these in the desired different Stroke ratios.

Durch den Wegfall der üblichen gekreuzten Seilschlaufe wird Bauraum gewonnen. Eine Anpassung an die unterschiedlichen Gegebenheiten verschiedener Fahrzeuge folgt überwiegend durch die Software der elektronischen Steuereinheit.By eliminating the usual crossed rope loop Space gained. An adaptation to the different Conditions of different vehicles mainly follow through the software of the electronic control unit.

Nachfolgend wird die Erfindung anhand eines Ausführungsbeispiels aufgrund der dargestellten Figur näher erläutert. Es zeigt:

The invention is explained in more detail below on the basis of an exemplary embodiment based on the figure shown. It shows:
Figure 1
- Schematic representation of a cable window lifter with two separate cables and separate motor drives.

Die Erfindung ist in all jenen Anwendungsfällen nutzbar, in denen die Vorteile des doppelsträngigen Seilfensterhebers mit der Notwendigkeit eines nicht parallelen Scheibenabzugs gepaart werden sollen. Derartige Aufgabenstellungen treten bei solchen versenkbaren Fensterscheiben auf, die eine starke, aber nicht gleichmäßige sphärische Krümmung besitzen. Dadurch ergibt sich bei Einsatz eines doppelsträngigen Seilfensterhebers, dessen Führungsschienen in Bereichen unterschiedlich starker Scheibenkrümmung angeordnet sind, die Notwendigkeit, die Fensterscheibe an diesen Stellen mit jeweils unterschiedlichem Hub zu verfahren. Besonders die großen vorderen Fensterscheiben zwischen der A- und B-Säule eines Kraftfahrzeugs stellen oft entsprechende Anforderungen. Grundsätzlich lassen sich aber auch die hinteren, zwischen der B- und C-Säule geführten Fensterscheiben mit den beschriebenen Fensterhebern verstellen.The invention can be used in all those applications in the advantages of the double-strand cable window lifter with the need for a non-parallel disc trigger to be paired. Such tasks occur with such retractable window panes, the one have strong but not uniform spherical curvature. This results in the use of a double strand Cable window lifter, its guide rails in areas disc curvatures of different strength are arranged, the need to use the window pane in these places to move each different stroke. Especially that large front window panes between the A and B pillars of a motor vehicle often have corresponding requirements. Basically, the rear, window panes guided between the B and C pillars adjust the described window regulators.

Die Ausführungsform gemäß der schematischen Darstellung von Figur 1 dient zur Lösung der Aufgabenstellung, wobei der Hub an den beiden Führungsschienen eines Seilfensterhebers nicht gleich groß sein soll.The embodiment according to the schematic representation of Figure 1 is used to solve the task, the Stroke on the two guide rails of a cable window lifter should not be the same size.

Der Seilfensterheber der Figur 1 besteht aus zwei Antrieben 6A, 6B, die an der Fensterscheibe 7 befestigt sind und Mitnehmer 10A''', 10B''' tragen, die mit dem Profil der Führungsschienen 1A''', 1B''' in formschlüssiger Verbindung stehen. Zwischen den Enden (Einspannstellen 500) der Führungsschienen 1A''', 1B''' sind separate Seile 5A, 5B gespannt. Sie umschlingen die Seiltrommeln 60A, 60B, die vom jeweiligen Antrieb 6A, 6B in Drehbewegung versetzt werden können. Dadurch windet sich der mit der Fensterscheibe 7 verbundene Antrieb 6A, 6B aufwärts bzw. abwärts.The cable window lifter of Figure 1 consists of two drives 6A, 6B, which are attached to the window pane 7 and Carriers 10A '' ', 10B' '' carry with the profile of the guide rails 1A '' ', 1B' '' in positive connection stand. Between the ends (clamping points 500) of the guide rails 1A '' ', 1B' '' are separate ropes 5A, 5B curious; excited. They loop around the rope drums 60A, 60B, the set in rotation by the respective drive 6A, 6B can be. This causes the window pane to twist 7 connected drive 6A, 6B upwards or downwards.

Da beide Antriebe 6A, 6B von einer (nicht dargestellten) gemeinsamen elektronischen Steuereinheit angesteuert werden, können an den beiden Führungsschienen 1A''', 1B''' unterschiedliche Hübe bzw. Hubgeschwindigkeiten gefahren werden. In Verbindung mit einer Positionserkennung können auch komplizierte Scheibenabläufe realisiert werden. Since both drives 6A, 6B from one (not shown) common electronic control unit can be controlled, can on the two guide rails 1A '' ', 1B' '' different strokes or lifting speeds become. In connection with a position detection can complicated disc processes can also be realized.
