Description

Die Erfindung betrifft einen Bowdenrohr-Fensterheber mit Seillängenausgleich gemäß dem Oberbegriff des Patentanspruchs 1. Sie gewährleistet mit einfachen Mitteln auch den Ausgleich vergleichsweise großer Seillängungen, ohne die Seilschlaufe übermäßig zu verspannen.The invention relates to a Bowden tube window lifter Rope length compensation according to the preamble of the claim 1. It also guarantees that with simple means Compensation for comparatively large rope lengths, without the To tighten the rope loop excessively.

Aus der DE 38 29 922 C2 ist ein Bowdenrohr-Fensterheber mit einer geschlossenen Seilschlaufe bekannt, die über an den Enden einer Führungsschiene gelagerten Umlenkrollen geführt ist. Die Verstellkraft wird von einer Antriebseinheit mit einer Seiltrommel erzeugt, deren Gehäuse zwei parallele Seilausgänge aufweist. Beim Drehen der Seiltrommel wird das Seil in die eine oder andere Richtung über die Seiltrommel gewickelt und verschiebt dabei den mit der Seilschlaufe verbundenen Gleiter, der einerseits mit der Führungsschiene im formschlüssigen, verschieblichen Eingriff steht und andererseits an der Fensterscheibe befestigt ist.From DE 38 29 922 C2 there is a Bowden tube window lifter a closed rope loop known to the End of a guide rail mounted guide rollers is. The adjustment force is provided by a drive unit generated a rope drum, the housing of which two parallel Has rope exits. When you turn the rope drum, it will Rope in one direction or the other over the rope drum wrapped and moves it with the rope loop connected slider, the one with the guide rail is in a form-fitting, slidable engagement and on the other hand is attached to the window pane.

Auf den Enden der parallelen Seilausgänge des Seiltrommelgehäuses sind separate Seilhülsen aufgesteckt. Die freien Enden der Seilhülsen weisen verdickte Enden auf, in denen die Enden der flexiblen Bowdenrohre eingesteckt sind. Andererseits stützen sich zwischen den verdickten Enden und dem Gehäuse der Seiltrommel Schraubenfedern ab, die die Seilschlaufe unter Spannung halten. Mit zunehmender Seillängung werden die verschieblichen Seilhülsen etwas mehr aus ihrer Führung im Seiltrommelgehäuse herausgeschoben, was quasi einer Verlängerung des Bowdenrohres gleichkommt.On the ends of the parallel cable exits of the cable drum housing separate cable sleeves are attached. The free Ends of the cable sleeves have thickened ends in which the ends of the flexible Bowden tubes are inserted. On the other hand lean between the thickened ends and the Housing the rope drum from coil springs that secure the rope loop keep under tension. With increasing rope elongation the sliding cable sleeves are a little more out of theirs Guide in the cable drum housing pushed out, what quasi is equivalent to an extension of the Bowden tube.

Von Nachteil ist jedoch, daß der beschriebene Seillängenausgleich ein relativ großes Umkehrspiel aufweist, da infolge einer Drehrichtungsumkehr mal die Schraubenfeder des einen Seilausganges und mal die Schraubenfeder des anderen Seilausganges je nach Belastung mehr oder weniger zusammengedrückt wird. Dieses Umkehrspiel läßt sich zwar durch die Verwendung stärkerer Federn verkleinern, jedoch mit dem Nachteil größerwerdender Reibung im Bowdensystem und dem damit verbundenen Wirkungsgradverlust des Antriebssystems. Außderdem muß der vorgesehene Ausgleichsweg zur Kompensierung der Seillängung in beiden Seilhülsen vorgehalten werden.The disadvantage, however, is that the rope length compensation described has a relatively large backlash, as a result a reversal of the direction of rotation times the coil spring of one Rope exit and times the coil spring of the other rope exit depending on the load more or less compressed becomes. This reversal game can be done by Reduce the use of stronger springs, but with the Disadvantage of increasing friction in the Bowden system and the associated loss of efficiency of the drive system. In addition, the intended compensation path for compensation the rope elongation held in both rope sleeves become.

Aus der DE 27 50 904 A1 ist ein Bowdenrohr-Fensterheber der voranbeschriebenen Art bekannt, dessen von einer Spannfeder beaufschlagte Seilhülsen von einer der Spannkraft entgegenwirkenden Sperre abgestützt sind. Dazu trägt jede Seilhülse sägezahnförmige Elemente, in die ein federartiges Sperrelement einrasten kann. Das Sperrelement verhindert, daß bei Betätigung (Belastung) des Fensterhebers die Spannfeder zusammengedrückt wird. Somit kann ein Umkehrspiel nicht auftreten. Nachteilig ist jedoch, daß die beschriebene Vorrichtung auch solche Seillosen ausgleicht, die infolge der Verspannung des Fensterhebers im unbelasteten Bereich des Seiles am anderen Seilausgang auftreten. Eine solche Seillose entspricht keiner echten Seillosen (Spiel) und führt bei ihrem Ausgleich nach der Entlastung des Fensterhebers zu bleibenden Verspannungen im System. Dadurch verschlechert sich der Wirkungsgrad und erhöht sich der Verschleiß der Verstellvorrichtung. Außerdem führt diese Spannung zu vorzeitiger weiterer Seillängung, wodurch ein besonders großer Ausgleichsweg in der Vorrichtung zum Seillängenausgleich vorgehalten werden muß.From DE 27 50 904 A1 is a Bowden tube window lifter known type known, of a tension spring acted upon rope sleeves by one counteracting the tension force Lock are supported. Each rope sleeve carries with it sawtooth-shaped elements into which a spring-like locking element can snap into place. The locking element prevents Actuation (load) of the window regulator compresses the tension spring becomes. So a reverse game cannot occur. The disadvantage, however, is that the described Device also compensates for those ropes that result the tension of the window lifter in the unloaded area of the rope occur at the other rope exit. Such Ropeless does not correspond to a real ropeless (game) and leads in their compensation after relieving the window regulator permanent tension in the system. This worsened efficiency and wear increases the adjusting device. This tension also leads to premature further rope elongation, whereby a particularly large compensation path in the device for Rope length compensation must be kept.

Eine weitere Variante dieser Druckschrift sieht eine verschiebbar oder exzentrisch gelagerte Seilumlenkrolle am Ende der Führungsschiene vor, die mit Unterstützung eines Spannelements bei Auftreten einer Seillosen eine entsprechende Verstellbewegung ausführen soll. Durch eine Sperre mit Formschlußelementen wird sichergestellt, daß eine Rückstellbewegung bei Belastung des Fensterhebers ausgeschlossen wird. Zusätzlich zu den vorstehend beschriebenen Nachteilen verursachen Stellbewegungen der Seilumlenkrollen eine veränderte winklige Seilführung, die zusätzlich zu Reibung und Verschleiß führen.Another variant of this publication sees one being displaceable or eccentrically mounted rope pulley on End of the guide rail with the support of a An appropriate tensioning element when a rope loose occurs Perform adjustment movement. Through a lock with positive locking elements ensures that a Resetting movement when the window regulator is loaded is excluded becomes. In addition to those described above Disadvantages cause adjustment movements of the rope pulleys a changed angled rope guide, which in addition to Cause friction and wear.

Aus der EP 0 607 589 A1 ist eine stufenlos arbeitende Vorrichtung zum Ausgleich von Seillängungen bekannt. Die in einem Basiskörper verschieblich gelagerten Seilhülsen stehen mit einem federartigen Klemmelement in Eingriff, das eine Bewegung der Seilhülse nur in Richtung der Spannfeder zuläßt und sich am Basiskörper abstützt.EP 0 607 589 A1 describes a continuously operating device known to compensate for rope lengthening. In the a basic body of slidable cable sleeves are engaged with a spring-like clamping element, the a movement of the cable sleeve only in the direction of the tension spring allows and is supported on the base body.

Der Nachteil dieser Vorrichtung besteht vor allem in der für einen sicheren Betrieb, das heißt zum sicheren Ausschluß einer Rückstellbewegung der Seilhülse notwendigen hohen Flächenpressung zwischen dem Klemmelement und der Seilhülse. Dies aber kann bei Auftreten großer Kräfte in Verbindung mit hohen Temperaturen leicht zu Beschädigungen des Kunststoffkörpers der Seilhülse und sogar zum Ausfall der Ausgleichsvorrichtung führen. The main disadvantage of this device is that for safe operation, that is, for safe exclusion a return movement of the cable sleeve necessary high surface pressure between the clamping element and the Rope sleeve. But this can occur when large forces occur Combination with high temperatures easy to damage of the plastic body of the rope sleeve and even to failure the compensation device.

Der Erfindung liegt die Aufgabe zugrunde, einen gattungsgemäßen Bowdenrohr-Fensterheber so auszubilden, daß ausschließlich sogenannte echte Seillosen ausgeglichen und unerwünschte Verspannungen des Verstellsystems vermieden werden.The invention has for its object a generic Train Bowden tube window lifters so that only so-called real rope lots balanced and unwanted tension in the adjustment system avoided become.

Erfindungsgemäß wird die Aufgabe durch die Merkmale des Patentanspruchs 1 gelöst. Die Unteransprüche geben Vorzugsvarianten der Erfindung an.According to the invention, the object is characterized by the features of Claim 1 solved. The subclaims give preferred variants of the invention.

Dementsprechend wird durch ein für beide Seilhülsen gemeinsames Verriegelungselement eine Kraffkopplung zwischen den Seilhülsen hergestellt. Diese Kraftkopplung erlaubt eine Ausgleichsbewegung einer oder beider Seiihülsen nur, wenn beide Seilhülsen - und somit beide zur Seiltrommel führenden Seilabschnitte - im wesentlichen unbelastet sind. Sobald der Fensterheber betätigt wird, kommt es in Abhängigkeit von der Drehrichtung des Antriebes (Heben oder Senken der Fensterscheibe) zur Belastung des einen oder des anderen Seilabschnittes. Insbesondere in den Anschlagspositionen der Fensterscheibe, wo der Antrieb sein maximales Drehmoment erreicht, treten große Verspannungen des Fensterhebersystems auf, die im allgemeinen mit einer relativ großen "scheinbaren" Seillose im nichtbelasteten Seilabschnitt verbunden sind. Der Ausgleich einer solchen nicht echten Seillose wird durch die Erfindung sicher verhindert, wodurch unnötig mechanische Verspannungen im System und die damit verbundenen Nachteile vermieden werden.Accordingly, a common for both rope sleeves Locking element a force coupling between the Rope sleeves made. This coupling of forces allows one Compensating movement of one or both sheaths only if both rope sleeves - and thus both leading to the rope drum Rope sections - are essentially unloaded. As soon as the window lifter is operated, it depends on the direction of rotation of the drive (lifting or lowering the window pane) to load one or the other Section of rope. Especially in the stop positions the window where the drive is at its maximum When the torque is reached, there is great tension in the window regulator system on that generally with a relative large "apparent" ropes in the unloaded rope section are connected. The balance of such is not real rope lots is reliably prevented by the invention, whereby unnecessary mechanical tension in the system and the associated disadvantages can be avoided.

Sogenannte echte Seillosen liegen nur im unbelasteten Zustand des Fensterhebers vor, deren Ausgleich führt nicht zu unerwünschten Verspannungen. So-called real rope lots are only in an unloaded state of the window regulator, their compensation does not lead to unwanted tension.

Gemäß der Erfindung kann die Ausgleichsbewegung durch eine oder zwei Seilhülsen erfolgen. Im zuletzt genannten Fall tritt neben der Kraftkopplung auch eine Synchronisierung der Ausgleichsbewegungen der beiden Seilhülsen auf, wobei diese nicht unbedingt 1:1 erfolgen muß, das heißt, die Seilhülsen können auch unterschiedlich lange Wege verschoben werden.According to the invention, the compensating movement by a or two rope sleeves. In the latter case In addition to the power coupling, synchronization also occurs the compensatory movements of the two cable sleeves, whereby this does not necessarily have to be 1: 1, that is, the Rope sleeves can also have different lengths of travel become.

Für Bowdenrohr-Fensterheber, die einen parallelen Seilausgang aus dem Antrieb (Seiltrommelgehäuse) aufweisen, sieht eine Vorzugsvariante der Erfindung einen einstückigen Grundkörper vor, in dem beide Seilhülsen sowie eine gemeinsame Anschlagsfläche für das Verriegelungselement integriert sind. Oie Verriegelung - und damit die Unterbindung einer Rückstellbewegung - kann stufig, insbesondere feinstufig, durch Verwendung von Verzahnungselementen und darin eingreifende Verriegelungselemente erfolgen. Hierbei können die Verzahnungselemente entlang des Verschiebeweges des Grundkörpers, also parallel zu den Seilausgängen, am Grundkörper selbst oder am Gehäuse des Antriebes (des Seiltrommelgehäuses) angeordnet sein, wobei sich die Verriegelungselemente am jeweils anderen Körper befinden. Die Verzahnung weist vorzugsweise eine sägezahnähnliche Form auf. Die zugehörigen Verriegelungselemente sollten als federnde Zungen ausgebildet sein.For Bowden tube window regulators that have a parallel rope exit from the drive (cable drum housing) a preferred variant of the invention in one piece Base body in which both rope sleeves as well as a common one Integrated stop surface for the locking element are. Oie locking - and thus the tie-down a return movement - can be staged, especially fine-stepped, by using gear elements and in it engaging locking elements take place. Here you can the gear elements along the displacement path of the Base body, i.e. parallel to the rope exits, on the base body itself or on the housing of the drive (the cable drum housing) be arranged, the locking elements on the other body. The gearing preferably has a sawtooth-like shape. The associated locking elements should be as resilient Tongues are formed.

Es besteht jedoch auch die Möglichkeit eines stufenlosen Ausgleichs der Seillose. Dazu wird als Verriegelungselement ein drehbar gelagerter Exzenter verwendet, der mit einer vorgespannten Feder in Verbindung steht. Diese Feder übt auf den Exzenter ein so ausreichend großes Drehmoment aus daß bei Auftreten einer Seillose der Grundkörper in Verschieberichtung bewegt werden kann. Aufgrund der Selbsthemmung der Vorrichtung oder einer Rückdrehsicherung wird verhindert, daß der Grundkörper bei Belastung des Fensterhebers durch das Bowdenrohr zurückgedrückt werden kann. Idealerweise ist der Exzenter mit Feder, vorzugsweise Schrauben- oder Spiralfeder, bezüglich des Gehäuses der Seiltrommel ortsfest gelagert, während die ihm zugeordnete Anschlagsfläche einstückig im Material des Grundkörpers angeformt ist.However, there is also the possibility of a stepless one Compensation for the rope lots. This is done as a locking element a rotatably mounted eccentric used with a biased spring is connected. That feather exerts a sufficiently large torque on the eccentric from that in the event of a rope loose the base body in Movement direction can be moved. Because of the self-locking the device or a reverse rotation lock prevents the base body when the window lifter is loaded can be pushed back through the Bowden tube. Ideally, the eccentric is preferably spring Coil or coil spring, with respect to the housing of the Rope drum stored stationary, while the one assigned to it Stop surface in one piece in the material of the base body is molded.

Für eine einfache Montierbarkeit des Seils weist jede Seilhülse des Grundkörpers einen durchgehenden, sich in Seilrichtung erstreckenden Schlitz auf, durch den das Seil eingelegt werden kann.Each rope sleeve shows for easy assembly of the rope of the main body a continuous, in the rope direction extending slot through which the rope can be inserted.

Die Erfindung ist aber auch auf Bowdenrohr-Fensterheber mit winklig zueinander stehenden Seilhülsen anwendbar. Dazu wird ein drehbarer Exzenter verwendet, der übereinander, das heißt entlang seiner Drehachse, zwei separate exzentrisch verlaufende Anschlagsflächen aufweist. Jede dieser exzentrischen Anschlagsflächen steht in Verbindung mit der Anschlagfläche einer Seilhülse. Vorzugsweise ist auch dieser Exzenter bezüglich der Seiltrommel ortsfest angeordnet.The invention is also with Bowden tube window lifters Rope sleeves can be used at an angle to each other. To a rotatable eccentric is used, one above the other, that is, along its axis of rotation, two separate eccentrically has running stop surfaces. Any of these eccentric stop faces is in connection with the Stop surface of a rope sleeve. Preferably too this eccentric with respect to the rope drum arranged stationary.

Falls eine im Verhältnis 1:1 synchronisierte Verstellbewegung der Seilhülsen gewünscht sein sollte, so weisen die beiden Anschlagflächen des zweistufigen Exzenters die gleiche Kontur auf und sind zueinander genau um den Winkel verdreht, den die Seilhülsen miteinander einschließen. Sobald die Kontur der exzentrischen Anschlagflächen voneinander abweichen und/oder der zwischen ihnen eingeschlossene Winkel nicht mit dem Winkel zwischen den Seilausgängen (Seihülsen) übereinstimmt, erfolgt eine vom Verhältnis 1:1 abweichende synchrone Stellbewegung (Ausgleichsbewegung) der Seilhülsen. Das heißt, die Länge des Stellweges der einenbSeilhülse unterscheidet sich von der Länge des Stellweges der anderen Seilhülse.If an adjustment movement synchronized in a ratio of 1: 1 the sleeves should be desired, so the two stop surfaces of the two-stage eccentric same contour and are exactly at the angle to each other twisted, the rope sleeves enclose with each other. As soon as the contour of the eccentric stop faces from each other deviate and / or the trapped between them Angle not with the angle between the rope exits (Pod pods), the ratio is 1: 1 deviating synchronous actuating movement (compensating movement) the rope sleeves. That is, the length of the travel of the A rope sleeve differs from the length of the travel the other rope sleeve.

Falls eine Ausgleichsbewegung durch die Verschiebung nur einer Seilhülse erfolgen soll, so ist die Kontur des Exzenterabschnitts, der mit der anderen nicht verschieblichen Seilhülse in Eingriff tritt, kreisförmig und konzentrisch zur Exzenterachse auszubilden. Eine Drehbewegung des Exzenters führt somit nur noch zur Verschiebung einer Seilhülse, während die andere Seilhülse ausschließlich zur Aufrechterhaltung der Kraftkopplung dient.In the event of a compensatory movement due to the shift only a cable sleeve, the contour of the eccentric section is the one that cannot be moved with the other Rope sleeve engages, circularly and concentrically to form the eccentric axis. A rotary movement of the eccentric thus only leads to the displacement of a rope sleeve, while the other rope sleeve is for maintenance only serves the coupling of forces.

Der Eingriff dieser Seilhülse mit der konzentrischen Kreisfläche des Exzenters sollte über verzahnungsähnliche Formschlußelemente hergestellt werden, um gleichzeitig die Funktion einer Rückdrehsicherung gewährleisten zu können.The engagement of this rope sleeve with the concentric circular area the eccentric should have gear-like form-locking elements are manufactured to simultaneously the To be able to guarantee the function of a reverse rotation lock.

Bei der Auslegung des Federelements, das auf die Seilhülsen direkt oder über den Exzenter indirekt in Verschieberichtung einwirkt, sollte berücksichtigt werden, daßE - je nach dem verwendeten Konstruktionsprinzip der Erfindung (Erfindungsvariante) - dem Verstellweg ein maximal doppelt so langer Seilausgleichsweg gegenüber steht. Der Ausgleich einer eventuell vorliegenden Seillose erfolgt in der Regel bei einer Umkehrung der Belastungsrichtung des Fensterhebers .Denn dabei wird ein Teil der Seillosen vom unbelasteten zum belasteten Seilstrang transportiert, so daß für einen kurzen aber für den Seillängenausgleich ausreichenden Zeitraum an beiden Seileingängen der Seilausgleichsvorrichtung eine Seillose anliegt, die ausgeglichen werden kann. Für den Fall, daß das Federelement stark genug ist, einen Teil der Seillose von einem Seilausgang zum anderen zu verlagern, das heißt, das Seil herumzuziehen, kann ebenfalls ein Seillängenausgleich erfolgen.When designing the spring element, which on the rope sleeves directly or indirectly via the eccentric in the direction of displacement acts, it should be taken into account that E - depending on the construction principle of the invention used (variant of the invention) - The adjustment path a maximum of twice long rope compensation path faces. The compensation if there is a rope loose, this is usually done with a reversal of the load direction of the window regulator Because part of the ropes will be unloaded transported to the loaded rope, so that for a short one, but sufficient for rope length compensation Period at both rope entrances of the rope compensation device there is a rope loose that can be compensated. In the event that the spring element is strong enough, one Part of the rope lots from one rope exit to the other shifting, that is, pulling the rope around, can also rope length compensation.

Figuren 1a und 1b zeigen die Vorder- und Rückansicht der Platzierung einer Ausführungsvariante der erfindungsgemäßen Seillängenausgleichsvorrichtung 1 auf einer in der Fahrzeugtür zu befestigenden Grundplatte 3, die auch den (nicht dargestellten) Antrieb, wie Handkurbelantrieb oder Motorantrieb mit der Seiltrommel 2 trägt. Die Erfindung wird am Beispiel eines einsträngigen Bowdenrohr-Fensterhebers, dessen geschlossene Seilschlaufe 20 über zwei Seilumlenkrollen 8 geführt und von der Seiltrommel 2 angetrieben ist, näher erläutert. Mit dem Seilabschnitt zwischen den Seilumlenkrollen 8 steht ein Mitnehmer 7 in fester Verbindung, an dem wiederum die Fensterscheibe befestigt ist. Im allgemeinen wird der Mitnehmer 7 von einer sogenannten (nicht dargestellten) Führungsschiene geführt, die sich entlang des Verschiebeweges der Fensterscheibe erstreckt. Die Bowdenrohre 200 erlauben eine an die konkreten Bedingungen in der Fahrzeugtür weitestgehend angepaßte Seilführung. Ihre Enden sind einerseits in parallele Seilausgänge der Seilhülsen 110 eingesetzt (siehe auch Figuren 1d bis 1f) und stützen sich andererseits an (nicht dargestellten) Anschlagflächen der oberen und unteren Seilumlenkung im Bereich der Seilumlenkrollen 8 ab.Figures 1a and 1b show the front and rear view of the Placement of an embodiment variant of the invention Rope length compensation device 1 on one in the vehicle door to be attached base plate 3, which also the (not shown) Drive, such as a hand crank drive or motor drive with the cable drum 2. The invention is on Example of a single-strand Bowden tube window lifter, whose closed rope loop 20 over two rope pulleys 8 guided and driven by the cable drum 2, explained in more detail. With the rope section between the rope pulleys 8 is a driver 7 in a fixed connection, to which the window pane is attached. In general the driver 7 of a so-called (not shown) guided guide rail that runs along of the displacement path of the window pane extends. The Bowden tubes 200 allow one to the specific conditions in cable guide largely adapted to the vehicle door. Your Ends are on the one hand in parallel rope exits of the rope sleeves 110 used (see also Figures 1d to 1f) and are based on the other hand on (not shown) stop surfaces the upper and lower rope deflection in the area of Cable pulleys 8 from.

Zwischen der Seiltrommel 2 und Seillängenausgleichsvorrichtung 1 verläuft das Seil 20 offen und in direkter Verbindung, das heißt, es wird nicht in Bowdenrohren 200 geführt. Wie in der Schnittdarstellung von Figur 1c zu erkennen ist, besteht die Seillängenausgleichsvorrichtung 1 im wesentlichen aus drei Teilen: einem drehbaren Grundkörper 12, der in direkter Verbindung zur Grundplatte 3 steht, einer Feder 13, die auf den drehbaren Grundkörper 12 ein Drehmoment ausübt, und einem verschieblichen Grundkörper 11, der auf dem drehbaren Grundkörper 12 in Gegenrichtung der Stützkräfte der Bowdenrohre 200 auf die Seillängenausgleichsvorrichtung 1 verschieblich lagert.Between the rope drum 2 and rope length compensation device 1, the rope 20 runs openly and in direct connection, that is, it is not routed in Bowden tubes 200. As can be seen in the sectional view of FIG. 1c, there is the rope length compensation device 1 essentially from three parts: a rotatable base body 12, the is in direct connection to the base plate 3, a spring 13, a torque on the rotatable base body 12 exercises, and a displaceable base body 11, which the rotatable base body 12 in the opposite direction of the supporting forces of the Bowden tubes 200 on the rope length compensation device 1 slidably mounted.

Der drehbare Grundkörper 12 besteht im wesentlichen aus einem äußeren Stützring 120, der die Stützkräfte der Bowdenrohre 200 über ein als Materialausstellung ausgebildetes Stützelement 30 der Grundplatte 3 abstützt, einem inneren Stützring 121, an dem die im Loch 31 eingehängte Feder 13 angreift, und einem auf der Gegenseite angeformten Exzenter 10, der in eine Öffnung des verschieblichen Grundkörpers 11 eingreift. Zur Gewährleistung einer einfachen Montierbarkeit der Vorrichtung weisen die parallel verlaufenden Seilhülsen 110 durchgehende seitliche Längsschlitze 112 auf, durch die das Seil 20 geführt ist.The rotatable base body 12 consists essentially of an outer support ring 120, which supports the Bowden tubes 200 via a trained as a material exhibition Support element 30 of the base plate 3 supports an inner Support ring 121 on which the spring 13 suspended in hole 31 attacks, and an eccentric formed on the opposite side 10, which in an opening of the movable base body 11th intervenes. To ensure easy assembly the device have the parallel Rope sleeves 110 through lateral longitudinal slots 112 through which the rope 20 is guided.

Aus Figur ld sind die Einzelheiten der Seillängenausgleichsvorrichtung 1 gut zu erkennen. Demnach befindet sich der Exzenter 10 in einer Position, in der seine Drehachse 100 den kleinstmöglichen Abstand zur Anschlagfläche 111 des verschieblichen Grundkörpers 11 einnimmt. Dabei hat die Seillängenausgleichsvorrichtung 1 von der Drehachse der Seiltrommel 2 einen Abstand A. Bei Anliegen einer hinreichend großen Stützkraft der Bowdenrohre 200 auf die Seileingänge der Seilhülsenll0 wird diese Position beibehalten. Eine Verschiebung des Grundkörpers 11 durch den drehmomentbeaufschlagten Exzenter 10 wird auch dann nicht erfolgen, wenn die besagte Stützkraft nur von einem der beiden Bowdenrohre 200 aufgebracht wird, zum Beispiel bei einer großen antriebsseitigen oder abtriebsseitigen Belastung des Fensterhebers. Die dabei im unbelasteten Seilstrang entstehende sogenannte "nicht echte" Seillose wird also nicht ausgeglichen und kann somit auch nicht zu unerwünschten Verspannungen des Seilfenstersystems führen.The details of the rope length compensation device are from FIG 1 easy to recognize. Accordingly, the Eccentric 10 in a position in which its axis of rotation 100 the smallest possible distance to the stop surface 111 of the displaceable base body 11 occupies. The Rope length compensation device 1 from the axis of rotation of the Rope drum 2 a distance A. If one is sufficient great support force of the Bowden tubes 200 on the rope entrances the Seilhülsenll0 will keep this position. A displacement of the base body 11 by the torque applied Eccentric 10 will also not take place if the said support force only from one of the two Bowden tubes 200 is applied, for example in a large one drive-side or output-side loading of the window lifter. The resulting in the unloaded rope strand So-called "not real" rope lots are not compensated for and therefore can not cause unwanted tension of the rope window system.

Ist jedoch die auf den verschieblichen Grundkörper 11 einwirkende Bowdenstützkraft geringer als die von der Anschlagfläche 101 des Exzenters 10 ausgehende und auf die Anschlagfläche 111 einwirkende sowie parallel zum Seilausgang gerichtete Kraft, dann liegt eine (echte) Seillose vor, die durch eine Ausgleichsbewegung des verschieblichen Grundkörpers 11 ausgeglichen wird. Dabei kommt es zu einer Verdrehung des drehbaren Grundkörpers 11, was zu einer veränderten Lage des Exzenters 10 führt, wie in Figur le dargestellt. Damit einher geht eine Abstandsvergrößerung zwischen der Drehachse 100 und der Anschlagfläche 111, die exakt der Abstandsvergrößerung (Differenz zwischen Abstand B und Abstand A) zwischen der Seiltrommel 2 und dem Grundkörper 11 entspricht. Der Abstand des drehbaren Grundkörpers 12 bezüglich der Seiltrommel 2 ändert sich hingegen nicht. Seine Position bleibt weiterhin durch die Stützelemente 30, an die der äußere Ring 120 anliegt, fixiert. However, is that acting on the displaceable base body 11 Bowden support force less than that of the stop surface 101 of the eccentric 10 outgoing and on the stop surface 111 acting and parallel to the rope exit directed force, then there is a (real) rope loose, the through a compensating movement of the displaceable base body 11 is balanced. This leads to a twist of the rotatable base body 11, resulting in a changed Position of the eccentric 10 leads, as shown in Figure le. This is accompanied by an increase in distance the axis of rotation 100 and the stop surface 111, the exactly the distance increase (difference between distance B and distance A) between the cable drum 2 and the base body 11 corresponds. The distance of the rotatable body 12, however, changes with respect to the cable drum 2 Not. Its position remains due to the support elements 30, against which the outer ring 120 abuts.

Da eine Kraftkopplung zwischen den Stützstellen der Bowdenrohre 200 am Grundkörper 11 vorliegt, kann eine Verschiebung des Grundkörpers 11, und somit ein Seillängenausgleich, praktisch nur bei einem unbelastenden Fensterheber erfolgen. Sein Verschiebeweg ist stets halb so groß wie die ausgeglichene Seillose; die Vorrichtung eignet sich also besonders für Seilfensterheber, bei denen über die Einsatzdauer eine relativ große Seillängung erwartet wird.There is a force coupling between the support points of the Bowden tubes 200 is present on the base body 11, a shift can of the base body 11, and thus a rope length compensation, practically only with an unloaded window regulator respectively. Its displacement path is always half as big as that balanced rope lots; the device is therefore suitable especially for cable window lifters, where over the period of use a relatively large length of rope is expected.

Figur 1f zeigt die gegenüberliegende Seite der bisher beschriebenen Seillängenausgleichsvorrichtung 1 in perspektivischer Darstellung. Durch eine entsprechende Dimensionierung der zwischen äußerem Stützring 120 und innerem Stützring 121 angeordneten Feder 13 kann auf das Drehmoment des Exzenters 10 und somit auf axiale Verschiebekräfte Einfluß genommen werden. Ist die Feder 13 also stark genug, so kann auch ein Teil einer Seillosen des einen Seilstranges zum anderen Seilstrang hinübergedrückt werden. Dadurch wird eine weitestgehend vollständige Ausgleichung vorhandener Seillosen gewährleistet, ohne Verspannungen im System zu riskieren.Figure 1f shows the opposite side of the previously described Rope length compensation device 1 in perspective Presentation. By appropriate dimensioning that between the outer support ring 120 and the inner support ring 121 arranged spring 13 can on the torque of Eccentric 10 and thus influence on axial displacement forces be taken. If the spring 13 is strong enough, it can also part of a rope of the one rope strand for other rope strand are pushed over. This will a largely complete adjustment of existing ones Rope-less guaranteed, without tension in the system too take risk.

Aus dem Test von Versuchsmodellen der erfindungsgemäßen oben beschriebenen Seillängenausgleichsvorrichtung 1 ist bekannt, daß eine starre Lagerung des drehbaren Grundkörpers 12 auf einer Welle bei abtriebsseitiger Belastung des Fensterhebers zu Rückstellbewegungen des Exzenters 10 führen kann, wenn diese Rückstellbewegung nicht durch ein Sperrelement blockiert ist. Einfacher und sicherer ist jedoch der in den Figuren 1 a bis 1c dargestellte Aufbau, bei dem eine fliegende Lagerung unter Führung der Stützelemente 30 gewählt wurde. Die dort eingeleiteten Stützkräfte am äußeren Ring 120 greifen also auf einem relativ großen Durchmesser an, was dem drehbaren Grundkörper 12 Selbsthemmung gegen Rückdrehung und somit gegen eine Rückstellbewegung des verschieblichen Grundkörpers 11 verleiht.From the test of experimental models of the invention Rope length compensation device 1 described above known that a rigid mounting of the rotatable body 12 on a shaft with the load on the output side Window lifter for resetting movements of the eccentric 10 can lead if this return movement is not caused by a Blocking element is blocked. Is easier and safer however the structure shown in FIGS. 1 a to 1 c, in which a flying storage under the guidance of the support elements 30 was chosen. The supporting forces introduced there the outer ring 120 therefore grips a relatively large one Diameter on what the rotatable body 12 self-locking against reverse rotation and thus against a return movement of the displaceable base body 11.

Eine weitere Ausführungsvariante des Erfindungsprinzips zeigt Figur 2, ebenfalls mit parallelen Seilausgängen der Seilhülsen 410. Diese Seillängenausgleichsvorrichtung 4 besitzt einen einstückigen verschieblichen Grundkörper 41, an dessen Anschlagfläche 412 sich eine Druckfeder 43 abstützt. Das gegenüberliegende Ende der Druckfeder 43 lagert an einem Bock 420, der Bestandteil des unbeweglichen, an der Grundplatte 3 festgelegten Grundkörpers 42 ist. Stützkräfte der Bowdenrohre 200 werden vom Grundkörper 41 über dessen Verzahnung 411, die mit der paßfähigen Gegenverzahnung (Formschlußelemente 421) des Grundkörpers 42 im Eingriff steht, in die Grundplatte des Fensterhebers eingeleitet.Another embodiment variant of the principle of the invention shows Figure 2, also with parallel rope exits of the Rope sleeves 410. This rope length compensation device 4 has a one-piece displaceable base body 41, a compression spring 43 is supported on its stop surface 412. The opposite end of the compression spring 43 is supported on a trestle 420, which is part of the immovable the base plate 3 is fixed body 42. Supporting forces of the Bowden tubes 200 are from the base body 41 its toothing 411, that with the matching counter toothing (Form-locking elements 421) of the base body 42 in engagement is introduced into the base plate of the window regulator.

Die Formschlußelemente 411, 421 sind vorzugsweise sägezahnförmig ausgebildet, wobei der flache Winkel in die Richtung des Seillängenausgleichs weist, um eine möglichst geringe Kraft zur Verschiebung des Grundkörpers 42 aufbringen zu müssen. Die steilen Flanken der Formschlußelemente 411, 421 sollen eine Rückstellbewegung sicher verhindern. Im Vergleich zur eingangs beschriebenen Variante mit Exzenterverstellung kann der Seillängenausgleich hier nicht stufenlos, sondern entsprechend der Geometrie der Verzahnung nur stufig erfolgen.The form-locking elements 411, 421 are preferably sawtooth-shaped formed, the flat angle in the direction of the rope length compensation has the lowest possible Apply force to shift the base body 42 to have to. The steep flanks of the positive locking elements 411, 421 should reliably prevent a return movement. Compared to the variant described above with eccentric adjustment the rope length compensation cannot be stepless here, but only according to the geometry of the gearing done in stages.

Die Figuren 3a und 3b zeigen eine Seillängenausgleichsvorrichtung 5 für Bowdenrohr-Fensterheber mit winklig zueinander verlaufenden Seilausgängen. Mithin können die verschieblichen Grundkörper 51a, 51b nicht, wie beim Ausführungsbeispiel von Figur 1, starr miteinander in Verbindung stehen. Figures 3a and 3b show a rope length compensation device 5 for Bowden tube window lifters with angles to each other running rope exits. So the moveable Base body 51a, 51b not, as in the exemplary embodiment of Figure 1, are rigidly connected.

Jeder Grundkörper 51a, 51b besitzt eine Anschlagsfäche 510a, 510b, die jeweils der Anschlagfläche 521a des Exzenters 520a beziehungsweise der Anschlagfläche 521 des Exzenters 520b zugeordnet ist. Da die Exzenter 520a, 520b fest mit dem in der Achse 50 drehbaren Grundkörper 52 in Verbindung steht, besteht auch hier eine Kraftkopplung zwischen den beiden Abstützungen der Bowdenrohrenden. Das heißt, ein Seillängenausgleich ist nur möglich, wenn beide Seilschlaufen quasi unbelastet sind.Each base body 51a, 51b has a stop surface 510a, 510b, each of the stop surface 521a of the eccentric 520a or the stop surface 521 of the eccentric 520b is assigned. Because the eccentrics 520a, 520b are fixed with the base body 52 rotatable in the axis 50 in connection stands, there is also a force coupling between the two supports of the Bowden tube ends. That is, a Rope length adjustment is only possible if both rope loops are virtually unencumbered.

Die perspektischen schematischen Darstellungen von Figur 3a und Figur 3b bilden die vorstehend beschriebene Erfindungsvariante in ihrer Ausgangsposition ab, noch bevor eine Drehung des Grundkörpers 52 sowie des damit verbundenen Exzenters 520a, 520b zu einer Verschiebung der Grundkörper 51a, 51b geführt hat, in den die Bowdenrohrenden aufnehmenden Seilhülsen integriert sind. Eine mit dem drehbaren Grundkörper 52 gekoppelte (nicht dargestellte) Feder erbringt, analog der Variante von Figur 1, das für den gegebenfalls erforderlichen Seillängenausgleich notwendig Drehmoment. Sämtliche Teile der Seillängenausgleichsvorrichtung 5 sind in geeigneter Weise auf einer Grundplatte oder dergleichen zu lagern.The perspective schematic representations of Figure 3a and FIG. 3b form the variant of the invention described above in their starting position even before one Rotation of the base body 52 and the associated Eccentrics 520a, 520b to shift the base body 51a, 51b has led into the receiving the Bowden tube ends Rope sleeves are integrated. One with the rotating one Basic body 52 provides a coupled spring (not shown), analogous to the variant of Figure 1, for the eventual required rope length compensation necessary Torque. All parts of the rope length compensation device 5 are in a suitable manner on a base plate or to store the like.

Eine weitere Erfindungsvariante, die jedoch der von Figur 3 weitestgehend gleicht, ist in Figur 4 dargestellt. Diese Seillängenausgleichsvorrichtung 6 verwendet nur einen Exzenter 520b, dessen Anschlagfläche 521b mit der Anschlagfläche 610b eines zugeordneten verschieblichen Grundkörpers 61b im Eingriff steht. Der andere Grundkörper 61a steht jedoch mit seiner verzahnten Anschlagfläche 610a der kreisrunden, ebenfalls verzahnten Anschlagfläche 621a des in der Achse 60 drehbar gelagerten Grundkörpers 62 in Verbindung. Da der Grundkörper 62 und der Exzenter 620b fest miteinander verbunden und vorzugsweise als einstückiges Kunststoffteil ausgeführt sind, ist also die Kraftkopplung der beiden Seilausgänge wiederum sichergestellt. Bei einer Drehbewegung des Grundkörpers 62 kommt es jedoch ausschließlich für den verschieblichen Grundkörper 61b zu einer Stellbewegung, die einen Ausgleich der Seillosen bewirkt. Der andere Grundkörper 61a übernimmt lediglich die schon erwähnte Kraftkopplung sowie die Sicherung der Seillängenausgleichsvorrichtung 6 gegen eine Rückstellbewegung infolge eventuell bowdenrohrseitiger Stützkräfte auf den verschieblichen Grundkörper 61b.Another variant of the invention, however, that of FIG. 3 largely identical, is shown in Figure 4. This Rope length compensation device 6 uses only one Eccentric 520b, its stop surface 521b with the stop surface 610b of an associated displaceable base body 61b is engaged. The other base body 61a stands however, with its toothed stop face 610a of the circular, also toothed stop surface 621a of the in the Axis 60 rotatably mounted base body 62 in connection. Since the base body 62 and the eccentric 620b firmly together connected and preferably as a one-piece plastic part executed, is the force coupling of the two Rope exits in turn ensured. With a rotary movement of the base body 62, however, it comes exclusively for the displaceable base body 61b for an actuating movement, which balances the ropes. The other Base body 61a only takes over the one already mentioned Power coupling and securing the rope length compensation device 6 against a return movement as a result Bowden tube-side support forces on the movable Basic body 61b.
