Abstract

The cable (3) is coupled to a driving member (2) moving along the rail (1). It runs round guides (4) at the rail ends, and is coupled to a drum (5) on the drive mechanism (6). The drum is situated at the end of the rail and also acts as a cable guide, and the motor and drive mechanism can also be mounted on the rail, typically at the bottom. With the driving member in the bottom position, the cable on the drum can be immediately adjacent to it, being further away from it in the top position. Where there are front and rear rails, each with a driving member, the cable is reeved in a figure-8 pattern, the drum being at the bottom end of one of the rails.

Description

Die Erfindung betrifft einen Seilzug-Fensterheber mit motorischem Antrieb, insbesondere für den Einbau in Fahrzeugen o. dgl., bestehend aus wenigstens einer Führungsschiene mit einem darin geführten, mit der Fensterscheibe verbindbaren Mitnehmer, wobei der Seilzug mit dem Mitnehmer gekoppelt sowie mittels i. w. im Bereich der Enden der Führungsschiene angeordneten Umlenkmitteln geführt ist und mit einer Seiltrommel de Antriebes in Antriebsverbindung steht.The invention relates to a cable window regulator with a motor drive, in particular for installation in vehicles or the like, consisting of at least one guide rail with a driver guided therein, which can be connected to the window pane, the cable cable being coupled to the driver and by means of i. w. is guided in the region of the ends of the guide rail arranged deflection means and is in drive connection with a cable drum de drive.

Ein derartiger Seilzug-Fensterheber ist bspw. aus der DE 36 15 578 C1 bekannt. Ein vergleichbarer, allerdings handbetätigter Fensterheber ist desweiteren bspw. aus der DE 195 06 226.4 zu entnehmen.Such a cable window regulator is known, for example, from DE 36 15 578 C1. A comparable, but manually operated window lifter can also be found, for example, in DE 195 06 226.4.

Der Antrieb, bestehend aus einem Elektromotor und einer Seiltrommel zum Betätigen des Fensterhebers ist üblicherweise auf halber Hubhöhe mit einem Adapter an der Führungsschiene befestigt oder in anderer Weise ortsfest an der Fahrzeugtür angeordnet. U. U. kann es vorkommen, daß der Platz auf halber Türhöhe für die Anordnung des Elektromotors nicht ausreicht. Dies ist insbesondere dann der Fall, wenn die Innenverkleidung zur Türaußenseite hin gezogen ist, um bspw. Kartentaschen, Konsolen oder dgl. an der Türinnenverkleidung anzubringen und dennoch auch in diesen Fällen genügend Bewegungsfreiheit für den Fahrer zu ermöglichen. Unter Umständen werden auch Lautsprecherboxen für Radioanlagen bei Kraftfahrzeugen in halber Türhöhe angeordnet, so daß auch insoweit der Raum für die Anordnung des Elektromotors des Fensterhebers nicht zur Verfügung steht.The drive, consisting of an electric motor and a cable drum for actuating the window lifter, is usually fastened to the guide rail at half the lifting height with an adapter or is arranged in another manner in a stationary manner on the vehicle door. It may happen that the space at half the door height is not sufficient for the arrangement of the electric motor. This is particularly the case when the inner panel is pulled towards the outside of the door, for example to attach card pockets, consoles or the like to the inside panel of the door and still allow sufficient freedom of movement for the driver in these cases as well. Under certain circumstances, loudspeakers for radio systems in motor vehicles are arranged at half the door height, so that the space for the arrangement of the electric motor of the window regulator is not available.

Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, einen Fensterheber der eingangs genannten Art dahingehend weiterzubilden, daß bei einfacher und bequemer Montage, sowie kostengünstiger Herstellung genügend Stauraum im Mittelbereich der Fahrzeugtür zur Verfügung steht.Proceeding from this, the object of the invention is to develop a window lifter of the type mentioned at the outset such that there is sufficient storage space in the central region of the vehicle door with simple and convenient assembly and cost-effective manufacture.

Diese Aufgabe wird nach der Erfindung bei dem Seilzug-Fensterheber mit den eingangs genannten Merkmalen i. w. dadurch gelöst, daß die Seiltrommel des motorischen Antriebs i. w. im Bereich eines Endes der Führungsschiene angeordnet ist und ein Umlenkmittel für den Seilzug bildet. Hierdurch wird gewährleistet, daß im Mittelbereich der mit dem erfindungsgemäßen Seilzug-Fensterheber ausgerüsteten Fahrzeugtür ausreichend Stauraum zur Verfügung steht und auch für eine ausreichende Bewegungsfreiheit für den Fahrer gesorgt ist. Dadurch, daß die Seiltrommel des Antriebs selbst ein Umlenkmittel für den Seilzug bildet, entfällt gegenüber den herkömmlichen Fensterhebern ein ansonsten erforderliches zusätzliches Umlenkmittel. Hierdurch können die Herstellungskosten des Fensterhebers weiter reduziert werden. Ein weiterer mit der Erfindung erzielbarer Vorteil besteht darin, daß der Seilzug über alle Umlenkungen in gleicher Richtung gebogen wird, was sich auf die Lebensdauer des Seilzuges äußerst günstig auswirkt, da die ansonsten auftretenden Wechselbiegungen des Seilzuges vermieden sind.This object is achieved according to the invention in the cable window regulator with the features mentioned at the outset. w. solved in that the cable drum of the motor drive i. w. is arranged in the region of one end of the guide rail and forms a deflection means for the cable pull. This ensures that there is sufficient storage space available in the central region of the vehicle door equipped with the cable-operated window lifter according to the invention and that sufficient freedom of movement for the driver is also provided. Because the cable drum of the drive itself forms a deflecting means for the cable pull, an additional deflecting means that is otherwise required is not required compared to conventional window regulators. As a result, the manufacturing costs of the window lifter can be reduced further. Another advantage that can be achieved with the invention is that the cable is bent over all deflections in the same direction, which has an extremely favorable effect on the life of the cable, since the alternating bending of the cable that would otherwise occur is avoided.

Von Vorteil ist der motorische Antrieb unmittelbar an der Führungsschiene montiert. Durch diese Maßnahme kann auf einen ansonsten erforderlich werdenden zusätzlichen Adapter zur Festlegung des Antriebes an der Führungsschiene verzichtet werden.The motorized drive is advantageously mounted directly on the guide rail. This measure makes it possible to dispense with an additional adapter, which would otherwise be necessary, for fixing the drive on the guide rail.

Nach einer weiteren, vorteilhaften Ausführungsform der Erfindung ist die Seiltrommel im Bereich eines unteren, im eingebauten Zustand bodenseitigen Endes der Führungsschiene angeordnet. Diese Maßnahme erweist sich insbesondere dann von Vorteil, wenn in dem Schachtbereich der Fahrzeugtür neben der Fensterscheibe nicht genügend Raum für den Antrieb zur Verfügung steht. Sofern in Sonderfällen ein solcher Raum zur Unterbringung des Antriebes dennoch vorhanden sein sollte, besteht natürlich auch die Möglichkeit, den Antrieb im Bereich des oberen Endes der Führungsschiene anzubringen.According to a further advantageous embodiment of the invention, the cable drum is in the region of a lower end of the guide rail on the bottom in the installed state arranged. This measure proves to be particularly advantageous if there is not enough space for the drive in the shaft area of the vehicle door next to the window pane. If such a space for accommodating the drive should nevertheless be available in special cases, there is of course also the possibility of mounting the drive in the region of the upper end of the guide rail.

Eine weitere, besonders vorteilhafte Ausgestaltung der Erfindung zeichnet sich dadurch aus, daß durch entsprechende Auslegung der Wickelrichtung der Seilzuges auf der Seiltrommel in einer untersten Position des Mitnehmers der Seilzug auf einem der Führungsschienen nächstliegenden Abschnitt der Seiltrommel angeordnet ist, während in einer oberen Position des Mitnehmers der Seilzug auf einem der Führungsschiene weiter abliegenden Abschnitt der Seiltrommel angeordnet ist. Hierdurch ist ein Verkippen des Mitnehmers, insbesondere in einer unteren Position bei einer Öffnungsstellung der Fensterscheibe vermieden. Der Seilzug läuft somit in der unteren Stellung des Mitnehmers i. w. parallel zum Boden der Führungsschiene auf der Seiltrommel.A further, particularly advantageous embodiment of the invention is characterized in that, by appropriately designing the winding direction of the cable on the cable drum in a lowermost position of the driver, the cable is arranged on a section of the cable drum closest to the guide rails, while in an upper position of the driver the cable is arranged on a section of the cable drum which is further away from the guide rail. This prevents the driver from tilting, in particular in a lower position when the window pane is in an open position. The cable runs i in the lower position of the driver. w. parallel to the bottom of the guide rail on the cable drum.

Eine andere vorteilhafte Ausgestaltung der Erfindung bei einem Seilzug-Fensterheber mit einer vorderen und hinteren Führungsschiene und jeweils einem darin geführten Mitnehmer, die mit dem insbesondere in Form einer gekreuzten Schleife bzw. in 8-Form angeordneten Seilzug gekoppelt sind, besteht darin, daß die Seiltrommel im Bereich eines unteren Endes einer der Führungsschienen angeordnet ist.Another advantageous embodiment of the invention in a cable window regulator with a front and rear guide rail and in each case a driver guided therein, which are coupled to the cable in particular in the form of a crossed loop or in the form of an 8, is that the cable drum one of the guide rails is arranged in the region of a lower end.

Die Erfindung ist somit gleichermaßen von Vorteil bei einem Einschienen- wie auch einem Zweischienen-Fensterheber einsetzbar.The invention is thus equally advantageous to use with a monorail as well as a two-rail window lifter.

Dabei besteht die Möglichkeit, daß die Seiltrommel entweder an der vorderen Führungsschiene bzw. an der hinteren Führungsschiene jeweils entweder am oberen oder am unteren Ende der jeweiligen Führungsschiene angeordnet ist. In jedem Fall wird im Mittelbereich der Fahrzeugtür Stauraum o. dgl. geschaffen, wobei zusätzlich ein ansonsten an der jeweiligen Führungsschiene erforderliches Umlenkmittel entfallen kann, da dieses Umlenkmittel durch die Seiltrommel des Antriebes des Fensterhebers ersetzt wird.It is possible for the cable drum to be arranged either on the front guide rail or on the rear guide rail, either at the upper or at the lower end of the respective guide rail. In any case, storage space or the like is created in the central region of the vehicle door, it also being possible to dispense with a deflecting means which is otherwise required on the respective guide rail, since this deflecting means is replaced by the cable drum of the window lifter drive.

Insbesondere dann, wenn die Seiltrommel an dem unteren Ende einer Führungsschiene angebracht ist, ergibt sich der weitere Vorteil einer Vereinfachung der Montage des Seilzug-Fensterhebers an der Türinnenseite, da der Seilzug-Fensterheber leichter durch die Montageöffnung in den Türkörper eingebracht werden kann.In particular, if the cable drum is attached to the lower end of a guide rail, there is the further advantage of simplifying the assembly of the cable window lifter on the inside of the door, since the cable window regulator can be introduced more easily through the mounting opening into the door body.

Von Vorteil ist der Antrieb im Bereich des Gehäuses der Seiltrommel an der Führungsschiene montiert.The drive is advantageously mounted in the area of the cable drum housing on the guide rail.

Weitere Ziele, Vorteile, Merkmale und Anwendungsmöglichkeiten der vorliegenden Erfindung ergeben sich aus der nachfolgenden Beschreibung der Ausführungsbeispieles anhand der Zeichnungen. Dabei bilden alle beschriebenen und/oder bildlich dargestellten Merkmale für sich oder in beliebiger sinnvoller Kombination den Gegenstand der vorliegenden Erfindung, auch unabhängig von ihrer Zusammenfassung in den Ansprüchen oder deren Rückbeziehung.Further objectives, advantages, features and possible uses of the present invention result from the following description of the exemplary embodiment with reference to the drawings. All of the described and / or illustrated features, alone or in any meaningful combination, form the subject matter of the present invention, regardless of how they are summarized in the claims or their relationship.

Show it:
Figure 1
a two-rail window regulator according to an embodiment of the invention and
Figure 2
a monorail window regulator according to a further embodiment.

Der Fensterheber gemäß Figur 1 besteht aus zwei im Abstand voneinander angeordneten Führungsschienen 1, welche an der Innenhaut der Fahrzeugtür, bspw. mittels einer Verschraubung mit zusätzlichen Höhenausgleich, festgelegt werden. Auf den Führungsschienen 1 ist jeweils ein mit der Scheibe verbindbarer Mitnehmer 2 in etwa vertikaler Richtung verschiebbar. Die Verschiebung des Mitnehmers 2 zum Öffnen und Schließen der Scheibe erfolgt über einen Seilzug 3, welcher über eine gekreuzte Schleife auf- und abbewegbar ist. Der Seilzug 3 ist mittels an den Enden der Führungsschienen 1 angeordneten Umlenkungen 4 geführt. Wie aus Figur 1 ersichtlich, ist die an der linken Führungsschiene 1 angeordnete Umlenkung durch die Seiltrommel 5 des Antriebes 6 des Fensterhebers gebildet. Hierdurch kann gegenüber dem Stand der Technik auf eine Umlenkung 4 verzichtet werden. Gleichzeitig wird der Vorteil erreicht, daß der Seilzug 3 nur jeweils in einer Richtung gebogen wird, so daß die von dem Stand der Technik her bekannte Wechselbiegung und damit ein erhöhter Verschleiß des Seilzuges 3 vermieden ist.The window lifter according to FIG. 1 consists of two spaced-apart guide rails 1, which are fixed to the inner skin of the vehicle door, for example by means of a screw connection with additional height compensation. On the guide rails 1, a driver 2 which can be connected to the disk can be displaced in an approximately vertical direction. The displacement of the driver 2 for opening and closing the pane is carried out by means of a cable 3, which can be moved up and down via a crossed loop. The cable 3 is guided by means of deflections 4 arranged at the ends of the guide rails 1. As can be seen from FIG. 1, the deflection arranged on the left guide rail 1 is formed by the cable drum 5 of the drive 6 of the window lifter. In this way, a deflection 4 can be dispensed with compared to the prior art. At the same time, the advantage is achieved that the cable 3 is only bent in one direction, so that the alternating bending known from the prior art and thus increased wear of the cable 3 is avoided.

Der Seilzug 3 selbst ist endlos auf die Seiltrommel 5 aufgewickelt. Durch Betätigen des Elektromotors in die eine oder andere Drehrichtung wird der Seilzug 3 längs der Führungsschienen 2 und damit über die Mitnehmer 2 die Fensterscheibe auf- und abbewegt. Ein weiterer Vorteil der Ausführungsform gemäß Figur 1 ist, daß auf einen zusätzlichen Adapter zur Festlegung des Antriebes 6 an der Führungsschiene verzichtet werden kann. Ein weiterer Vorteil ist, daß sich die Montage des Fensterhebers an der Türinnenseite vereinfacht, da der Fensterheber mit am unteren Ende der Einführungsschiene 1 angeordneten Antrieb sich leichter durch die Montageöffnung in den Türkörper einbringen läßt, als in dem Fall, wenn der Antrieb 6 nach dem Stand der Technik im mittleren Bereich der Führungsschiene angeordnet ist.The cable 3 itself is wound endlessly on the cable drum 5. By operating the electric motor in one or the other direction of rotation, the cable 3 is moved up and down along the guide rails 2 and thus via the catches 2. Another advantage of the embodiment according to FIG. 1 is that an additional adapter for fixing the drive 6 on the guide rail can be dispensed with. Another advantage is that the installation of the window lifter on the inside of the door is simplified, since the window lifter with the drive arranged at the lower end of the insertion rail 1 is easier to pass through the installation opening in allows the door body to be inserted than in the case when the drive 6 according to the prior art is arranged in the central region of the guide rail.

Die Montage des Antriebes 6 an der Führungsschiene 1 erfolgt vorteilhafterweise im Bereich des Gehäuses der Seiltrommel 5. Die Wickelrichtung des Seilzuges 3 auf der Seiltrommel 5 sollte dabei so ausgelegt werden, daß in der untersten Stellung des Mitnehmers 2 der Seilzug 3 auf der der Führungsschiene 1 nächstliegenden Rille der Seiltrommel 5 liegt, während bei in Schließstellung befindlichem Mitnehmer 2 der Seilzug 3 auf der weiter äußeren Rille der Seiltrommel 5 zu liegen kommt. Hierdurch ist ein Verkippen des Mitnehmers 2, insbesondere in einer unteren Position bei einer Öffnungsstellung der Fensterscheibe vermieden. Der Seilzug 3 läuft somit in der unteren Stellung des Mitnehmers 2 parallel zum Boden der Führungsschiene 1 auf die Seiltrommel 5.The drive 6 is advantageously mounted on the guide rail 1 in the region of the housing of the cable drum 5. The winding direction of the cable 3 on the cable drum 5 should be designed such that in the lowest position of the driver 2 the cable 3 on that of the guide rail 1 The closest groove of the cable drum 5 is located, while when the driver 2 is in the closed position, the cable pull 3 comes to rest on the further outer groove of the cable drum 5. This prevents the driver 2 from tilting, in particular in a lower position when the window pane is in an open position. The cable 3 thus runs in the lower position of the driver 2 parallel to the bottom of the guide rail 1 on the cable drum 5.

Figur 2 zeigt einen Einschienen-Fensterheber, wobei im Vergleich zu Figur 1 gleichen Bauteile mit identischen Bezugszeichen versehen sind. Mit Figur 2 soll insbesondere gezeigt werden, daß ein Umlenkmittel 4 bildende Seiltrommel 5 auch bei einem Einschienen-Fensterheber einsetzbar ist.FIG. 2 shows a monorail window lifter, the same components being provided with identical reference numerals in comparison to FIG. 1. FIG. 2 is intended in particular to show that a cable drum 5 forming a deflection means 4 can also be used with a monorail window regulator.

Ersichtlich kann bei den hier gewählten Ausführungsformen die sonst erforderliche Seilausgleichsfeder an dem einen Abgang des Gehäuses der Seiltrommel 5 entfallen. Allerdings kann insoweit im Bereich der Anlenkung des Mitnehmers 2 an dem Seilzug 3 eine Seilausgleichseinrichtung u. U. vorsehen werden.Obviously, in the embodiments chosen here, the otherwise required cable balancing spring on one outlet of the housing of the cable drum 5 can be omitted. However, in the area of the articulation of the driver 2 on the cable 3, a cable compensation device u. U. be provided.
