Definitions
- the invention relates to a double-strand cable window lifter for motor vehicles according to the preamble of claim 1.
- the window lifter is specially designed for guiding spherically curved window panes of a motor vehicle and, in the case of widely differing radii of curvature of the window pane at the locations of the two guide rails, ensures exact adherence to a predetermined pull-off path.
- single-strand cable window lifters often appears to be less advantageous for lifting and lowering large, spherically designed window panes, because tilting of the window pane cannot usually be avoided due to the insufficiently available driver base.
- the typical parallel trigger does not meet the requirements of the different trigger lengths at the locations of the respective guide rails. Therefore, the window pane inevitably tilts out of its intended trigger path, which can also lead to jamming.
- a cable window lifter is known from DE-C1 36 15 578, which represents a combination of two single-strand cable window lifters, each of the two closed cable loops being guided over a separate cable drum.
- a common drive wheel transmits the driving force to the two cable drums. The purpose of this construction is to avoid rope change bends and thus to improve the durability of the rope.
- the invention has for its object to develop a double-strand cable window lifter for motor vehicles, which ensures an exact deduction of a spherically curved window pane on an intended trigger path using a simple and inexpensive structural design.
- the window regulator should have a small footprint and allow good accessibility in the lock area.
- the object is achieved by a double-strand cable window lifter, of which at least one guide rail has means which bring about a change in the otherwise usual stroke length. If these means are to be used on the guide rail in the region of the smaller radius of curvature of the spherically curved window pane, these lead to a stroke shortening; and in the event that these means are to be used on the guide rail in the region of the larger radius of curvature, they lead to a stroke extension.
- Another option for moving a window pane on two guide rails with different lifting characteristics is the use of two separate ropes stretched along the guide rail, each of which is assigned a separate electric motor drive, which is controlled by a common electronic control unit.
- the desired different stroke ratios can be used.
- the software of the electronic control unit mainly adapts to the different conditions of different vehicles.
- the invention can be used in all those applications in which the advantages of the double-strand cable window lifter are to be paired with the need for a non-parallel window trigger. Such tasks occur with such retractable window panes that have a strong but not uniform spherical curvature.
- the guide rails of which are arranged in areas of different curvature of the pane this results in the need to move the window pane at these points with a different stroke in each case.
- the large front window panes between the A and B pillars of a motor vehicle often pose corresponding requirements.
- the rear window panes which are guided between the B and C pillars, can also be adjusted using the window lifters described.
- the invention provides various solution variants of the principle of the invention. Which of the stroke-shortening technical means should preferably be used depends on the specific conditions of the individual application.
- FIG. 1 schematically shows a double-strand cable window lifter
- the A-pillar-side guide rail 1A guide rail in the region of the smaller radius of curvature of the window pane
- the angle ⁇ with respect to the other B-pillar-side guide rail 1B.
- both the angle of inclination ⁇ and the lever length 3A of the compensating rail 3 which is dependent thereon are shown in a greatly exaggerated manner.
- the figure shows the carriers 10 A, 10 B guided on the guide rails 1 A, 1 B in their upper and lower stop positions, respectively.
- the compensating rail 3 in the form of a longitudinally slotted box profile, which is guided on a suitable shaped piece of the driver 10 A in the X direction (transverse to the withdrawal direction of the window pane 7) (see also FIG. 1 a).
- the pane holder 4 A is listed as a clamping element, between the clamping jaws of which the window pane 7 is clamped.
- the screw connection 30 is used to generate the clamping force for fastening the window pane to the compensating rail.
- the other driver 10 B is directly connected to the pane holder 4 A.
- Both guide rails 1 A, 1 B are of the same length and have at their ends deflection rollers 50, over which the rope loop 5 is guided.
- the drivers 10 B are firmly connected to the rope loop 5 in order to be able to absorb the adjusting force generated by a drive 6.
- Stroke 2A stroke 2B x cos ⁇ , wherein the stroke 2B of the guide rail 1B running parallel to the withdrawal direction of the window pane 7 corresponds exactly to the displacement length of the driver 10A on the inclined guide rail 1A.
- the distance between the pane holder 4 A and the driver 10 A changes continuously.
- the necessary compensation takes place through the sliding joint connection between the glider 10 A and the compensation rail 3.
- differently designed sliding joint connections can also be used.
- the pane holder 4 A can be displaceably mounted on the outer rail 3 or a sliding joint connection is designed with the inclusion of an elongated hole provided in the window pane 7.
- FIG. 2 schematically shows a further variant of the invention of a double-strand cable window lifter using a closed cable loop 5, which is guided over cable pulleys 50 and is connected to drivers 10A 'and 10B'.
- the driver 10B ' is slidably supported on the straight guide rail 1B' running parallel to the withdrawal direction and carries a disc holder 4B 'for attachment to the lower edge of the disc
- the other driver 10A' is on a guide rail 1A which is curved in the withdrawal plane (in the X direction) 'arranged. It is located in the area of the smaller radius of curvature and shortens the disc stroke in comparison to the same guide rail 1B '.
- FIG. 2a shows a section from FIG. 2. Accordingly, a compensating arm 3 ′ with a rectified elongated hole 310 ′ adjoins the driver 10A ′ at right angles, which is penetrated by the screw connection 30 ′ for fastening the disk holder 4A ′. With the cylindrical shaft 300 ', the elongated hole 310' forms a rotary sliding joint to compensate for the different angular positions of the driver 10A 'and the distance between the driver 10A' and the disk holder 4A 'which changes during the disk actuation.
- both drivers 10A ', 10B' travel the same length, but the stroke 2A 'is reduced compared to the stroke 2B' of the straight guide rail 1B '.
- the shorter the stroke the greater the smaller the radius of curvature R 'of the guide rail 1A', i.e. the greater the curvature of this guide rail 1 A '.
- the compensating arm 3 'pointing in the direction of the center of the radius of curvature of the guide rail 1A' apparently guides the disk holder 4A 'onto an arc of a circle whose radius is smaller than the radius R' of the guide rail 1A '.
- the degree of stroke shortening can therefore also be influenced by varying the distance of the disk holder 4A 'from the guide rail 1A'.
- FIGS. 3 to 3c A further embodiment variant of the invention is shown in FIGS. 3 to 3c.
- This is also a double-strand cable window lifter consisting of the usual components (guide rails 1A '', 1B ''; driver 10A '', 10B '' with pane holder 4A '', 4B ''; deflection rollers 50 for Guidance of the rope loop 5; Drive 6).
- the A-pillar-side guide rail 1A ′′ is arranged in the region of the smaller radius of curvature R A of the spherical window pane 7 between the outer door skin 8 and the window pane 7, while the other, B-pillar-side guide rail 1B ′′ is arranged in the region of the larger radius of curvature R B of the window pane 7 is fastened between the door interior trim 9 and the window pane 7.
- the radius of curvature R a ′′ of the A-pillar-side outer guide rails 1A ′′ has a larger amount than the radius of curvature R A of the window pane 7; conversely, the radius of curvature R b '' of the B-pillar-side inner guide rail 1B '' is larger than the radius of curvature R B of the window pane 7 in this area.
- the embodiment according to the schematic representation in FIG. 4 differs significantly from all the embodiment variants described so far; however, it also serves to solve the same problem, according to which the stroke on the two guide rails of a cable window lifter should not be the same size.
- the adjustment system consists of two drives 6A, 6B, which are attached to the window pane 7 and carry drivers 10A ′′′, 10B ′′′, which are positively connected to the profile of the guide rails 1A ′′′, 1B ′′′.
- Separate cables 5A, 5B are tensioned between the ends (clamping points 500) of the guide rails 1A ′′′, 1B ′′′. They loop around the cable drums 60A, 60B, which can be rotated by the drive.
- the drive 6A, 6B connected to the window pane 7 winds upwards and downwards.
- both drives 6A, 6B are controlled by a (not shown) common electronic control unit, different strokes or lifting speeds can be carried out on the two guide rails 1A ′′′, 1B ′′′. In conjunction with position detection, even complex disc sequences can be implemented.

Abstract
Description
Die Erfindung betrifft einen doppelsträngigen 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 double-strand cable window lifter for motor vehicles according to the preamble of claim 1. The window lifter is specially designed for guiding spherically curved window panes of a motor vehicle and, in the case of widely differing radii of curvature of the window pane at the locations of the two guide rails, ensures exact adherence to a predetermined pull-off 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 actuate spherically curved window panes in motor vehicles with arm window lifters, the window panes sliding in lateral guides of the vehicle door, which extend close to the door floor. These Lateral guides are necessary in order to be able to derive the forces occurring perpendicular to the plane of the pane. The disadvantage, however, is that the lateral guidance in the lock area often leads to space problems, especially if the door construction is particularly narrow. Therefore, if necessary, part of the side guide is designed as a separate additional part and used after the lock has been installed. Thus, an increased installation effort must 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 often appears to be less advantageous for lifting and lowering large, spherically designed window panes, because tilting of the window pane cannot usually be avoided due to the insufficiently available driver base.
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.Although the use of known conventional double-strand cable window lifters is suitable for safely guiding the window pane in the so-called Y direction (transverse to the plane of the pane) and for preventing the window pane from tilting, the typical parallel trigger does not meet the requirements of the different trigger lengths at the locations of the respective guide rails. Therefore, the window pane inevitably tilts out of its intended trigger path, which can also lead to jamming.
Aus der DE-C1 36 15 578 ist ein 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.A cable window lifter is known from DE-C1 36 15 578, which represents a combination of two single-strand cable window lifters, each of the two closed cable loops being guided over a separate cable drum. A common drive wheel transmits the driving force to the two cable drums. The purpose of this construction is to avoid rope change bends and thus to improve the durability of the rope.
Der Erfindung liegt die Aufgabe zugrunde, einen doppelsträngigen 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. Der Fensterheber soll einen geringen Platzbedarf aufweisen und eine gute Zugänglichkeit im Schloßbereich ermöglichen.The invention has for its object to develop a double-strand cable window lifter for motor vehicles, which ensures an exact deduction of a spherically curved window pane on an intended trigger path using a simple and inexpensive structural design. The window regulator should have a small footprint and allow good accessibility in the lock area.
Erfindungsgemäß wird die Aufgabe durch einen doppelsträngigen Seilfensterheber gelöst, von dem wenigstens eine Führungsschiene Mittel aufweist, die eine Veränderung der sonst üblichen Hublänge bewirken. Im Falle daß diese Mittel an der Führungsschiene im Bereich des kleineren Krümmungsradiuses der sphärisch gekrümmten Fensterscheibe zur Anwendung kommen sollen, führen diese zu einer Hubverkürzung; und im Falle daß diese Mittel an der Führungsschiene im Bereich des größeren Krümmungsradiuses zur Anwendung kommen sollen, führen diese zu einer Hubverlängerung.According to the invention, the object is achieved by a double-strand cable window lifter, of which at least one guide rail has means which bring about a change in the otherwise usual stroke length. If these means are to be used on the guide rail in the region of the smaller radius of curvature of the spherically curved window pane, these lead to a stroke shortening; and in the event that these means are to be used on the guide rail in the region of the larger radius of curvature, they lead to a stroke extension.
Dies kann beispielsweise durch folgende Unterprinzipien erreicht werden:
- (1) Die Führungsschiene im Bereich des kleineren Durchmessers der sphärischen Krümmung der Fensterscheibe (meistens im Bereich A-Säule des Kraftfahrzeuges) ist gegenüber der anderen Führungsschiene an der Stelle des größeren Durchmessers der Scheibenkrümmung in der Verschiebeebene der Fensterscheibe geneigt angeordnet. Dabei ist die Neigung so gewählt, daß der Gleiter beim Ablauf auf der Führungsschiene zwischen seiner oberen und seiner unteren Anschlagsposition genau den gewünschten (reduzierten) Hub ausführt. Zwischen dem Mitnehmer und dem Scheibenhalter (Scheibenbefestigung) ist ein quer zur Abzugsbahn wirkender Ausgleich notwendig, der die in Abhängigkeit von der Scheibenstellung unterschiedlichen Abstände zwischen dem Gleiter und dem Scheibenhalter kompensiert. Beispielsweise kann der Ausgleich von einer Ausgleichsschiene gewährleistet werden, die einerseits mit dem Mitnehmer (Gleiter) und andererseits mit dem Scheibenhalter in verschiebbarer Verbindung steht. Das Schiebegelenk kann dabei am Mitnehmer oder am Scheibenhalter angeordnet sein. Es ist aber auch möglich, die Ausgleichsbewegung über ein in der Fensterscheibe befindliches Langloch und ein darin eingreifendes Gleitelement des Mitnehmers zu gewährleisten.
- (2) Die Führungsschiene im Bereich des kleineren Krümmungsradiuses der sphärischen Fensterscheibe ist in der Abzugsebene quer zur Abzugsbahn derart gekrümmt, daß ein in das innere des Krümmungsradiuses weisender, mit dem Mitnehmer verbundener Ausgleichsarm die gewünschte Krümmung des Hubes im Vergleich zur anderen Führungsschiene bewirkt. Dabei steht der Ausgleichsarm mit dem Scheibenhalter über ein Dreh-Schiebegelenk in Verbindung. Zur Veränderung des Verhältnisses zwischen Verschiebestrecke des Mitnehmers und der Führungsschiene und dem tatsächlich realisierten Hub kann der Krümmunggrad der Führungsschiene und/oder die Hebelänge des Ausgleichsarms entsprechend angepaßt werden.
- (3) Die beiden Führungsschienen sind nicht wie bisher üblich auf der gleichen Seite der Fensterscheibe angeordnet. Vielmehr liegt die eine Führungsschiene im Bereich des kleineren Krümmungsradiuses der sphärischen Fensterscheibe im Außenraum zwischen Scheibe und Türaußenhaut und die andere Führungsschiene im Innenraum zwischen Fensterscheibe und der Türinnenverkleidung. Dabei ist der an die Scheibenkrümmung angepaßte Radius der außenliegenden Führungsschiene größer als der Scheibenkrümmungsradius an dieser Stelle und der Radius der innenliegenden Führungsschiene ist kleiner als der Scheibenkrümmungsradius an der entsprechenden Stelle. Eine Anpassung der Hübe der beiden Führungsschienen an die gegebenen konkreten Anforderungen eines Anwendungsfalls kann durch Veränderung des Abstandes der Fensterscheibe zur Führungsbahn der Führungsschiene erfolgen. So verringern entsprechende Hebellängen den Hub der äußeren Führungsschiene, während mit zunehmender Hublänge an der inneren Führungsschiene der Hub verringert wird.
- (1) The guide rail in the area of the smaller diameter of the spherical curvature of the window pane (usually in the A-pillar area of the motor vehicle) is inclined relative to the other guide rail at the location of the larger diameter of the window pane curvature in the plane of displacement of the window pane. The inclination is chosen so that the slider executes exactly the desired (reduced) stroke when it runs on the guide rail between its upper and lower stop positions. Between the driver and the disc holder (disc attachment) is a cross acting to the trigger path Compensation necessary, which compensates for the different distances depending on the position of the pane between the glider and the pane holder. For example, the compensation can be ensured by a compensation rail, which is on the one hand with the driver (glider) and on the other hand with the disc holder in a sliding connection. The sliding joint can be arranged on the driver or on the disc holder. However, it is also possible to ensure the compensating movement via an elongated hole in the window pane and a sliding element of the driver engaging therein.
- (2) The guide rail in the region of the smaller radius of curvature of the spherical window pane is curved in the take-off plane transversely to the take-off path in such a way that a compensating arm pointing into the inside of the radius of curvature and connected to the driver brings about the desired curvature of the stroke in comparison to the other guide rail. The compensating arm is connected to the disc holder via a rotating sliding joint. To change the relationship between the displacement distance of the driver and the guide rail and the actually realized stroke, the degree of curvature of the guide rail and / or the lever length of the compensating arm can be adjusted accordingly.
- (3) The two guide rails are not arranged on the same side of the window as usual. Rather, the one guide rail lies in the area of the smaller radius of curvature of the spherical window pane in the outer space between the pane and the outer skin of the door and the other guide rail lies in the inner space between the window pane and the door interior trim. The radius of the outer guide rail adapted to the curvature of the window is larger than the radius of curvature of the window at this point and the radius of the inner guide rail is smaller than the radius of curvature at the corresponding point. The strokes of the two guide rails can be adapted to the specific requirements of an application by changing the distance between the window pane and the guide track of the guide rail. Corresponding lever lengths reduce the stroke of the outer guide rail, while the stroke is reduced with increasing stroke length on the inner guide rail.
Allen beschriebenen Varianten ist der Vorteil zu eigen, daß der für doppelsträngige Seilfensterheber charakteristische strenge parallele Scheibenabzug mit einfachen Mitteln an die speziellen Bedürfnisse sphärisch gekrümmter Fensterscheibe angepaßt werden kann. Trotz gleich langer Verschiebewege der Mitnehmer auf den beiden Führungsschienen wird die Fensterscheibe örtlich mit unterschiedlichem Hub gewegt.All the variants described have the advantage that the strict parallel parallel window take-off, which is characteristic of double-strand cable window lifters, can be adapted to the special needs of spherically curved window windows with simple means. In spite of the same length of displacement of the drivers on the two guide rails, the window pane is moved locally with a different stroke.
Eine weitere Möglichkeit zur Verschiebung einer Fensterscheibe an zwei Führungsschienen mit unterschiedlicher Hubcharakteristik besteht in der Verwendung von zwei separaten, entlang der Führungsschiene gespannten Seilen, denen jeweils separate elektromotorische Antriebe zugeordnet sind, die von einer gemeinsamen elektronischen Steuereinheit angesteuert werden. Somit kann, insbesondere bei Verwendung einer sogenannten Positionserkennung der Fensterscheibe, in den gewünschten unterschiedlichen Hubverhältnissen verfahren werden.Another option for moving a window pane on two guide rails with different lifting characteristics is the use of two separate ropes stretched along the guide rail, each of which is assigned a separate electric motor drive, which is controlled by a common electronic control unit. Thus, in particular when using a so-called position detection of the window pane, the desired different stroke ratios can be used.
Durch den Wegfall der gekreuzten Seilschlaufe wird Bauraum gewonnen. Eine Anpassung an die unterschiedlichen Gegebenheiten verschiedener Fahrzeuge folgt überwiegend durch die Software der elektronischen Steuereinheit.By eliminating the crossed rope loop, installation space is gained. The software of the electronic control unit mainly adapts to the different conditions of different vehicles.

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 which the advantages of the double-strand cable window lifter are to be paired with the need for a non-parallel window trigger. Such tasks occur with such retractable window panes that have a strong but not uniform spherical curvature. When a double-strand cable window lifter is used, the guide rails of which are arranged in areas of different curvature of the pane, this results in the need to move the window pane at these points with a different stroke in each case. In particular, the large front window panes between the A and B pillars of a motor vehicle often pose corresponding requirements. In principle, however, the rear window panes, which are guided between the B and C pillars, can also be adjusted using the window lifters described.
Die Erfindung stellt verschiedene Lösungsvarianten des Erfindungsprinzip zur Verfügung. Welche der hubverkürzenden technischen Mittel vorzugsweise zur Anwendung kommen sollen, hängt von den konkreten Bedingungen des einzelnen Anwendungsfall ab.The invention provides various solution variants of the principle of the invention. Which of the stroke-shortening technical means should preferably be used depends on the specific conditions of the individual application.
Figur 1 stellt schematisch einen doppelsträngigen Seilfensterheber dar, dessen A-säulenseitige Führungsschiene 1A (Führungsschiene im Bereich des kleineren Krümmungsradiuses der Fensterscheibe) gegenüber der anderen, B-säulenseitigen Führungsschiene 1B mit einem Winkel α angeordnet ist. Zur Verdeutlichung des konstruktiven Aufbaus sind sowohl der Neigungswinkel α als auch die davon abhängige Hebelänge 3A der Ausgleichsschiene 3 stark übertrieben dargestellt.FIG. 1 schematically shows a double-strand cable window lifter, the A-pillar-
Die Abbildung zeigt die auf den Führungsschienen 1 A, 1 B geführten Mitnehmer 10 A, 10 B in ihrer jeweils oberen bzw. unteren Anschlagsposition. Gleiches gilt für die Ausgleichsschiene 3 in Form eines längsgeschlitzten Kastenprofils, das auf einem passenden Formstück des Mitnehmers 10 A in X-Richtung (quer zur Abzugsrichtung der Fensterscheibe 7) verschiebbar geführt ist (siehe auch Figur la). Der Scheibenhalter 4 A ist als Klemmelement aufgeführt, zwischen dessen Klemmbacken die Fensterscheibe 7 eingeklemmt wird. Zur Erzeugung der Klemmkraft zur Befestigung der Fensterscheibe an der Ausgleichsschiene dient die Schraubverbindung 30. Der andere Mitnehmer 10 B steht direkt mit dem Scheibenhalter 4 A in Verbindung.The figure shows the
Beide Führungsschienen 1 A, 1 B sind gleich lang und tragen an ihren Enden Umlenkrollen 50, über welche die Seilschlaufe 5 geführt ist. Die Mitnehmer 10 B stehen in fester Verbindung mit der Seilschlaufe 5, um die von einem Antrieb 6 erzeugte Verstellkraft aufnehmen zu können.Both
Bei Betätigung des Antriebes werden nun die Gleiter 10 A, 10 B auf den Führungsschienen 1 A, 1 B um die gleiche Wegstrecke verschoben. Wegen der Neigung der Führungsschiene 1 A um den Winkel α verkürzt sich aber der maximale Hub auf:
wobei der Hub 2B der parallel zur Abzugsrichtung der Fensterscheibe 7 verlaufenden Führungsschiene 1B genau der Verschiebelänge des Mitnehmers 10A auf der geneigten Führungsschiene 1A entspricht.When the drive is actuated, the
wherein the
Während des Hebens oder Senkens der Fensterscheibe 7 verändert sich der Abstand zwischen dem Scheibenhalter 4 A und dem Mitnehmer 10 A kontinuierlich. Der notwendige Ausgleich erfolgt durch die Schiebegelenkverbindung zwischen dem Gleiter 10 A und der Ausgleichsschiene 3. Natürlich sind auch anders gestaltete Schiebegelenkverbindungen einsetzbar. Beispielsweise kann der Scheibenhalter 4 A verschieblich an der Außenschiene 3 lagern oder es wird eine Schiebegelenkverbindung unter Einbeziehung eines in der Fensterscheibe 7 vorgesehenen Langlochs gestaltet.During the raising or lowering of the
Figur 2 zeigt schematisch eine weitere Erfindungsvariante eines doppelsträngigen Seilfensterhebers unter Verwendung einer geschlossenen Seilschlaufe 5, die über Seilrollen 50 geführt wird und mit Mitnehmern 10A' und 10B' in Verbindung stehen. Während der Mitnehmer 10B' auf der geraden, parallel zur Abzugsrichtung verlaufenden Führungsschiene 1B' verschiebbar lagert und einen Scheibenhalter 4B' zur Befestigung an der Scheibenunterkante trägt, ist der andere Mitnehmer 10A' auf einer in der Abzugsebene (in X-Richtung) gekrümmten Führungsschiene 1A' angeordnet. Sie befindet sich im Bereich des kleineren Scheibenkrümmungsradius und bewirkt eine Verkürzung des Scheibenhubes im Vergleich zu der gleich lagen anderen Führungsschiene 1B'.FIG. 2 schematically shows a further variant of the invention of a double-strand cable window lifter using a
Figur 2a zeigt einen Ausschnitt aus Figur 2. Demnach schließt sich rechtwinkelig an den Mitnehmer 10A' ein Ausgleichsarm 3' mit einem gleichgerichteten Langloch 310' an, das von der Schraubverbindung 30' zur Befestigung des Scheibenhalters 4A' durchgriffen wird. Mit dem zylindrischen Schaft 300' bildet das Langloch 310' ein Dreh-Schiebegelenk zum Ausgleich der unterschiedlichen Winkelstellungen des Mitnehmers 10A' und des sich während der Scheibenbetätigung ändernten Abstandes zwischen dem Mitnehmer 10A' und dem Scheibenhalter 4A'.FIG. 2a shows a section from FIG. 2. Accordingly, a compensating
Wird die Fensterscheibe 7 zwischen ihrer oberen und unteren Anschlagsposition verfahren, so legen zwar beide Mitnehmer 10A', 10B' einen gleichlangen Weg zurück, jedoch ist der Hub 2A' gegenüber dem Hub 2B' der geraden Führungsschiene 1B' reduziert. Die Hubverkürzung fällt um so stärker aus, je kleiner der Krümmungradius R' der Führungsschiene 1A', d.h., je stärker die Krümmung dieser Führungsschiene 1 A' ist.If the
Der in Richtung des Mittelpunktes des Krümmungradiuses der Führungsschiene 1A' weisende Ausgleichsarm 3' führt den Scheibenhalter 4A' scheinbar auf einen Kreisbogen, dessen Radius kleiner ist als der Radius R' der Führungsschiene 1A'. Also kann auch durch Variation des Abstandes des Scheibenhalters 4A' von der Führungsschiene 1A' auf den Grad der Hubverkürzung Einfluß genommen werden.The compensating arm 3 'pointing in the direction of the center of the radius of curvature of the
Anderseits ist es auch möglich, eine gerade ausgebildete Führungsschiene A-säulenseitig zu verwenden und eine gekrümmte B-säulenseitige Führungsschiene mit einem solchen Gleiter auszustatten, dessen Ausgleichsarm radial nach außen, also weg vom Mittelpunkt des Krümmungskreises weist. Dadurch wird an dieser Führungsschiene eine Hubvergrößerung hervorgerufen. Der Hub an der A-säulenseitigen Führungsschiene im Bereich des kleineren Krümmungsradiuses der Fensterscheibe 7 bleibt also verhältnismäßig kleiner. Die Erfindungsaufgabe läßt sich mit beiden Untervarianten gleichwertig lösen.On the other hand, it is also possible to use a straight guide rail on the A-pillar side and to equip a curved B-pillar-side guide rail with such a slider, the compensating arm of which points radially outward, ie away from the center of the circle of curvature. This causes an increase in stroke on this guide rail. The stroke on the A-pillar-side guide rail in the region of the smaller radius of curvature of the
Eine weitere Ausführungsvariante der Erfindung zeigen die Figur 3 bis 3c. Auch hier handelt es sich um einen doppelsträngigen Seilfensterheber bestehend aus den üblichen Komponenten (Führungsschienen 1A'', 1B''; Mitnehmer 10A'', 10B'' mit Scheibenhalter 4A'', 4B''; Umlenkrollen 50 zur Führung der Seilschlaufe 5; Antrieb 6). Die Besonderheit besteht jedoch darin, daß die A-säulenseitige Führungsschiene 1A'' im Bereich des kleineren Krümmungsradiuses RA der sphärischen Fensterscheibe 7 zwischen der Türaußenhaut 8 und der Fensterscheibe 7 angeordnet ist, während die andere, B-säulenseitig Führungsschiene 1B'' im Bereich des größeren Krümmungsradiuses RB der Fensterscheibe 7 zwischen der Türinnenverkleidung 9 und der Fensterscheibe 7 befestigt ist. Hierbei weist der Krümmungsradius Ra'' der A-säulenseitigen außenliegenden Führungsschienen 1A'' einen höheren Betrag als der Krümmungsradius RA der Fensterscheibe 7 auf; umgekehrt ist der Krümmungsradius Rb'' der B -säulenseitigen innenliegenden Führungsschiene 1B'' größer als der Krümmungsradius RB der Fensterscheibe 7 in diesem Bereich.A further embodiment variant of the invention is shown in FIGS. 3 to 3c. This is also a double-strand cable window lifter consisting of the usual components (
Zwischen den Mitnehmern 10A '', 10B'' bzw. deren neutralen Führungsbahn auf der Führungsschiene 1A'', 1B'' und den Scheibenhaltern 4A '', 4B'' besteht ein durch die Länge 3A'', 3B'' des Verbindungshebels 3'' definierter Abstand. Mit zunehmender Hebellänge 3A'', 3B'' wird ein von der Verschiebestrecke des Gleiters 10A'', 10B'' stärker abweichender Hub 2A'', 2B'' erzeugt. So führt der nach innen weisende Hebel 3'' an der A-säulenseitigen äußeren Führungsschiene 1A'' zu einer Hubverkürzung; hingegen bewirkt der nach außen weisende Hebel 3''' an der B-säulenseitigen inneren Führungsschiene 1B'' eine Hubvergrößerung. Durch Abstimmung der konstruktiven Bedingungen der Scheibenanbindung der beiden Führungsschienen 1A'', 1B'' wird der jeweilige Hub 2A'', 2B'' festgelegt.Between the
An dieser Stelle sei noch darauf hingewiesen, daß die zuletzt beschriebene Variante einen Bowdenfensterheber erfordert, damit das Seil 5 auch in der untersten Position der Fensterscheibe 7 unter die Scheibenunterkante hindurchgeführt werden kann.At this point it should be pointed out that the last described variant is a Bowden window lifter required so that the
Die Ausführungsform gemäß der schematischen Darstellung von Figur 4 weicht von allen bisher beschriebenen Ausführungsvarianten wesentlich ab; jedoch dient auch sie zur Lösung der gleichen Aufgabenstellung, wonach der Hub an den beiden Führungsschienen eines Seilfensterhebers nicht gleich groß sein soll.The embodiment according to the schematic representation in FIG. 4 differs significantly from all the embodiment variants described so far; however, it also serves to solve the same problem, according to which the stroke on the two guide rails of a cable window lifter should not be the same size.
Das Verstellsystem besteht aus zwei Antrieben 6A, 6B, die an der Fensterscheibe 7 befestigt sind und Mitnehmern 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 Antrieb in Drehbewegung versetzt werden können. Dadurch windet sich der mit der Fensterscheibe 7 verbundene Antrieb 6A, 6B aufwärts bzw. abwärts.The adjustment system consists of two
Da beide Antriebe 6A, 6B von einer (nichtdargestellten) 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
