Definitions

  • the invention relates to a vehicle door adjustment unit for a motor vehicle sliding door with a deflection device for deflecting a cable for automatic opening and/or closing of the motor vehicle sliding door.
  • Sliding motor vehicle doors are typically used for delivery vans and vans, and more recently also for passenger cars. What all sliding doors have in common is that they can be moved into an open position and into a closed position by means of a sliding movement. This sliding movement takes place essentially parallel to the side wall of the vehicle. The fact that unhindered loading and unloading and getting on and off is made possible is particularly advantageous.
  • sliding doors are increasingly being equipped with a motorized adjustment unit for automatic opening and/or closing.
  • An electric motor is typically used to drive the adjustment unit and, for the motorized adjustment of the sliding door, exerts a tensile force on a cable which is connected to the sliding door at the other end.
  • the sliding door is mounted on the outside of the vehicle so that it can be displaced laterally in the longitudinal direction of the motor vehicle, so that the sliding door can be slid back and forth in the longitudinal direction.
  • the cable runs inside the vehicle from the drive to a passage in the vehicle body from the inside to the outside and is guided and deflected through the passage by means of a deflection pulley in such a way that that the cable can run on the outside of the vehicle longitudinally in the opposite direction as on the inside, for example to be able to follow a closing movement of the sliding door or to open the sliding door automatically, i.e. motor-assisted.
  • the deflection roller which is rotatably mounted on a generally vertical axis of rotation, thus enables the cable to be guided in a U-shape around a wall-shaped body side.
  • the adjustment drive of the vehicle door adjustment unit for the motor vehicle sliding door is therefore generally not arranged directly behind the deflection roller, but rather at a suitable point in the body with sufficient installation space available.
  • the cable is therefore guided from the deflection roller to the adjustment drive by a guide means, in particular a sleeve similar to a Bowden cable.
  • the guideway or sleeve often curves around the intervening components between the idler pulley and the drive. As the cable moves alternately in opposite directions when opening and closing the sliding door, this can lead to the cable twisting about its own axis.
  • a vehicle door adjustment unit for a motor vehicle sliding door serves to solve the task.
  • Advantageous embodiments emerge from the dependent claims.
  • a vehicle door adjustment unit for a motor vehicle sliding door with a deflection device for deflecting a cable for automatic opening and/or closing of the motor vehicle sliding door having the cable and a first deflection pulley basically for deflecting the cable and a second deflection pulley with a U shaped or V-shaped cable receiving profile basically comprises for deflecting the same cable, wherein a first deflection axis of the first deflection roller and a second deflection axis of the second deflection roller are oriented perpendicularly or essentially perpendicularly to one another.
  • the first deflection roller and the second deflection roller are enclosed by a common housing, the housing of the deflection device being equipped with a first cavity for the first deflection roller and a second cavity for the second deflection roller, the first cavity being connected to the second cavity by a through-opening whose maximum opening width is greater than the rope diameter and optionally less than 1.5 times the thickness of the first pulley or second pulley.
  • the invention is based on the finding that providing a second deflection roller arranged vertically or essentially vertically behind the first deflection roller acts as a stopper for twisting the rope about its own axis and thus prevents twisting about its own axis due to the features of the invention specified above can be counteracted effectively.
  • Installing the deflection device in a passage from the outside to the inside of the motor vehicle body side can thus simultaneously enable the bonus effect of a sealing and protective effect against external influences.
  • the housing for just the first idler pulley would typically not be large enough to fully cover the passageway.
  • a particularly effective countermeasure can be made possible with the U-shaped or V-shaped cable receiving profile of the second and/or first deflection pulley.
  • Substantially perpendicular to one another includes in particular an angular range of ⁇ 20°, preferably ⁇ 15°, preferably ⁇ 10°, very particularly preferably ⁇ 5°.
  • the first deflection axis and the second deflection axis are at a distance from one another that is smaller than the sum of a first diameter or radius of one of the deflection rollers and a second radius of the other of the deflection rollers.
  • the distance can therefore be smaller than the diameter of the first and radius of the second deflection roller.
  • the distance can also be smaller than the radius of the first and diameter of the second deflection roller.
  • the distance can be smaller than the radius of the first and second deflection rollers.
  • the first deflection axis and the second deflection axis have the above-specified distance orthogonally to the first deflection axis and/or orthogonally to the second deflection axis.
  • the distance is therefore to be measured along a straight line orthogonal to the first deflection axis or orthogonal to the second deflection axis. It is also advantageous to measure the distance on a common straight line that is orthogonal to the first and second deflection axis.
  • a particularly effective countermeasure against twisting about the rope's own axis can be supported by a distance measured in such an oriented manner.
  • the distance corresponds at least to the first radius of the first deflection roller or to the second radius of the second deflection roller.
  • the distance between the intersection points of the deflection rollers with the respective deflection axes can also be measured.
  • the cable runs from the first deflection pulley directly to the second deflection pulley.
  • Running from the first deflection pulley to the second deflection pulley means that the cable is deflected successively by the first deflection pulley and the second deflection pulley.
  • Running directly from the first deflection roller to the second deflection roller means that no further deflection roller or other deflection means is arranged between the first deflection roller and the second deflection roller and acts on the cable.
  • the rope thus runs directly from the first deflection pulley to the second deflection pulley, with "running” meaning the geometric extension and not a feed movement.
  • a particularly effective countermeasure against twisting around the own axis of the rope can be supported in this way.
  • the cable runs tangentially to the first pulley and tangentially to the second pulley. If the rope were a line with no diameter, the first and second pulleys would share a common tangent. The tangent and the cable then rest at points on the first and second deflection rollers that are essentially offset by 90° or essentially 90°—or, to be more precise, in particular in the valley of a U-shaped cable receiving profile. A particularly effective countermeasure against twisting around the own axis of the rope can be supported in this way.
  • the cable is tensioned between the first and second deflection pulleys.
  • Tensioned essentially means running in a straight line.
  • the course of a tensioned rope during operation does not deviate by more than 1 mm, preferably 0.5 mm, from a straight line or sags by this amount.
  • a sufficiently large pulling force and/or short cable length is therefore always ensured.
  • the cable In the section of the cable between the first and second deflection rollers, the cable otherwise does not touch any other components. At most, unintentional contact with a housing or other means of protection surrounding the rope is possible, especially if the rope sags. Due to the tense state between the first and second deflection roller, grinding on another surface and thus wear is avoided.
  • the higher friction effects can also contribute to counteracting the rope twisting around its own axis.
  • the deflection device is designed in such a way that the rope is deflected by the first deflection pulley by at least 90°, preferably 135°, particularly preferably exactly or essentially 180°.
  • Deflecting by an angle means deflecting the angle from a cable section running to the deflection pulley to a cable section running away from the deflection pulley.
  • a deflection angle of 180° therefore means a complete reversal of direction.
  • a particularly effective countermeasure against twisting around the own axis of the rope can be supported in this way.
  • the deflection device is designed in such a way that the cable is guided through the second deflection pulley by at least 15°, preferably 30°, and/or at most 135°, preferably 90°; is deflected.
  • a particularly effective countermeasure against twisting around the own axis of the rope can be supported in this way.
  • Thickness means extension in the direction of the deflection axis.
  • a particularly high sealing effect can be made possible by a through-opening which is narrow in the manner described above.
  • a guide means in particular a cover, is provided for guiding and protecting the cable in front of or behind the deflection device.
  • Cover means in particular a tubular cover.
  • guide means are arranged behind the second deflection roller and/or vice versa, as seen from the first deflection roller.
  • a particularly high protection of the cable and a variable course of the path to the connection point on the sliding door or the drive can be made possible.
  • the guide means is firmly connected to a housing of the first deflection roller and/or second deflection roller.
  • a smooth and low-abrasion transition between the housing or the in particular second deflection roller to the guide means, in particular the casing, can thus be made possible.
  • the guide means is a Bowden cable-like sleeve and/or the sleeve and the cable form a Bowden cable, basically with a non-positive and/or positive coupling of the sleeve on the housing of the deflection device and with the other side on the housing of the drive.
  • the coupling can be done by sliding it on to the side, for example with a dovetail-like connection or a dovetail connection.
  • Bowden cable-like sheath means a tubular sheathing of the rope, which can transmit compressive and tensile forces.
  • the provision of a Bowden cable with the sleeve and the cable enables the motor vehicle sliding door to be opened and closed automatically by the drive.
  • the first deflection roller and the second deflection roller have the same diameter and/or are identical in construction.
  • a vehicle door adjustment unit can be manufactured in this way with a particularly small number of different parts and with little effort.
  • the figure 1 shows a wall-like motor vehicle body side from the inside, in which a variety of components 7, of which figure 1 only two of them, such as a loudspeaker or electronic component, are integrated as an example and diagrammatically.
  • a motor vehicle sliding door is laterally mounted on the outside of the wall-like motor vehicle body side or the vehicle along a guide rail 11 (in figure 1 hidden and represented by a dashed line) mounted translationally so that the sliding door can be slid longitudinally back and forth for opening and closing.
  • a vehicle door adjustment unit with a drive 10 is provided for automatic opening—preferably also closing—of the motor vehicle sliding door.
  • the drive 10 is not attached to the sliding door, but fixedly attached to a location provided for this purpose on the motor vehicle body next to the other components 7 .
  • the sliding door In an open position of the motor vehicle sliding door, the sliding door is behind the view figure 1 .
  • a cable 1, which the sliding door through the drive 10 from the open position to the closed position, ie to the left in the view of figure 1 , can move is connected to the drive 10 at one end and to the sliding door at the other end.
  • the cable 1 From the first end of the cable 1, which is connected or coupled to the sliding door by means of a cable end connection, the cable 1 runs via an outer cable path section 12, preferably at the level of the guide rail 11, in particular centrally thereto, along the outside of the motor vehicle body side to a passage 15 from the outside to the inside of the automobile body side.
  • the first deflection roller 3 is rotatably mounted on a vertical first deflection axis 6 in order to deflect the cable 1 in a U-shape around the wall-like side of the motor vehicle body.
  • the cable 1 runs from the first deflection pulley 3 directly to a second deflection pulley 4 which is rotatably mounted on a second deflection axis 8 which is horizontal and orthogonal to the motor vehicle body side.
  • a cable path section between the first and second deflection pulleys 3, 4 extends along a common tangential line 13 to the first and second deflection pulleys 3, 4 in such a way that the cable 1, after being released from the first deflection pulley 3 in a straight-line tensioned state, runs parallel to the guide rail 11 and parallel to the motor vehicle body side on the second deflection roller 4 touches down.

  • Twisting about the own axis of the rope 1 within the sheath 9 on the inner section of the rope path is effectively prevented from spreading to the first deflection roller 3 by the second deflection roller 4 oriented essentially perpendicularly to the first deflection roller 3 . It goes without saying that the same also applies to the second deflection device, which is not shown.
  • the deflection device 2 is selected in such a way that it is able to overcome a sealing force.

Description

Die Erfindung betrifft eine Fahrzeugtürverstelleinheit für eine Kraftfahrzeugschiebetür mit einer Umlenkeinrichtung zum Umlenken eines Seils für ein automatisches Öffnen und/oder Schließen der Kraftfahrzeugschiebetür.The invention relates to a vehicle door adjustment unit for a motor vehicle sliding door with a deflection device for deflecting a cable for automatic opening and/or closing of the motor vehicle sliding door.

Kraftfahrzeugschiebetüren werden typischerweise für Lieferwagen und Kleintransporter, in jüngerer Zeit zunehmend auch für Personenwagen eingesetzt. Allen Schiebetüren ist gemeinsam, dass sie durch eine Schiebebewegung in eine geöffnete Stellung und in eine geschlossene Stellung verstellbar sind. Diese Schiebebewegung erfolgt im Wesentlichen parallel zur Seitenwand des Fahrzeugs. Besonders vorteilhaft ist dabei die Tatsache, dass ein ungehindertes Be- und Entladen bzw. ein Ein- und Aussteigen ermöglicht wird.Sliding motor vehicle doors are typically used for delivery vans and vans, and more recently also for passenger cars. What all sliding doors have in common is that they can be moved into an open position and into a closed position by means of a sliding movement. This sliding movement takes place essentially parallel to the side wall of the vehicle. The fact that unhindered loading and unloading and getting on and off is made possible is particularly advantageous.

Insbesondere in Personenkraftfahrzeugen werden Schiebetüren zunehmend mit einer motorischen Verstelleinheit zum automatischen Öffnenund/oder Schließen ausgestattet. Ein Elektromotor dient typischerweise als Antrieb der Verstelleinheit und übt für die motorische Verstellung der Schiebetür eine Zugkraft auf ein Seil aus, das an dem anderen Ende mit der Schiebetür verbunden ist. Die Schiebetür ist an der Außenseite des Fahrzeugs seitlich in Längsrichtung des Kraftfahrzeugs verschiebbar gelagert, so dass die Schiebetür in Längsrichtung vor und zurück geschoben werden kann. Da sich der Antrieb in der Regel auf der Innenseite des Fahrzeugs insbesondere örtlich feststehend befindet, verläuft das Seil innerhalb des Fahrzeugs vom Antrieb bis zu einem Durchgang in der Fahrzeugkarosserie von der Innenseite zur Außenseite und wird mittels einer Umlenkrolle so durch den Durchgang geführt und umgelenkt, dass das Seil an der Außenseite des Fahrzeugs in Längsrichtung in die entgegengesetzte Richtung wie auf der Innenseite laufen kann, um beispielsweise einer Schließbewegung der Schiebetür folgen zu können oder die Schiebetür automatisch, also motorgestützt, aufzuziehen.In passenger vehicles in particular, sliding doors are increasingly being equipped with a motorized adjustment unit for automatic opening and/or closing. An electric motor is typically used to drive the adjustment unit and, for the motorized adjustment of the sliding door, exerts a tensile force on a cable which is connected to the sliding door at the other end. The sliding door is mounted on the outside of the vehicle so that it can be displaced laterally in the longitudinal direction of the motor vehicle, so that the sliding door can be slid back and forth in the longitudinal direction. Since the drive is usually located on the inside of the vehicle, in particular in a locally fixed manner, the cable runs inside the vehicle from the drive to a passage in the vehicle body from the inside to the outside and is guided and deflected through the passage by means of a deflection pulley in such a way that that the cable can run on the outside of the vehicle longitudinally in the opposite direction as on the inside, for example to be able to follow a closing movement of the sliding door or to open the sliding door automatically, i.e. motor-assisted.

Die an einer in der Regel vertikalen Drehachse rotierbar angebrachten Umlenkrolle ermöglicht somit das Seil U-förmig um eine wandförmige Karosserieseite herumzuführen.The deflection roller, which is rotatably mounted on a generally vertical axis of rotation, thus enables the cable to be guided in a U-shape around a wall-shaped body side.

Auf der Innenseite der Karosserie befinden sich üblicherweise eine Vielzahl von Komponenten wie z.B. Lautsprecherboxen, Elektronikbauteile usw. auf engem Raum. Der Verstellantrieb der Fahrzeugtürverstelleinheit für die Kraftfahrzeugschiebetür ist daher aus Platzgründen regelmäßig nicht unmittelbar hinter der Umlenkrolle, sondern an einer geeigneten Stelle in der Karosserie mit hinreichend verfügbarem Bauraum angeordnet. Durch ein Führungsmittel, insbesondere einer Hülle ähnlich wie bei einem Bowdenzug, wird das Seil daher von der Umlenkrolle zum Verstellantrieb geführt.On the inside of the body there are usually a large number of components such as loudspeaker boxes, electronic components, etc. in a confined space. For reasons of space, the adjustment drive of the vehicle door adjustment unit for the motor vehicle sliding door is therefore generally not arranged directly behind the deflection roller, but rather at a suitable point in the body with sufficient installation space available. The cable is therefore guided from the deflection roller to the adjustment drive by a guide means, in particular a sleeve similar to a Bowden cable.

Der Führungsweg bzw. die Hülle weisen häufig einen geschwungenen Verlauf um die zwischenliegenden Komponenten zwischen der Umlenkrolle und dem Antrieb auf. Im Zuge der Seilbewegung abwechselnd in entgegengesetzte Richtungen beim Öffnen und Schließen der Schiebetür kann es dadurch zu einem Verdrehen des Seils um seine eigene Achse kommen.The guideway or sleeve often curves around the intervening components between the idler pulley and the drive. As the cable moves alternately in opposite directions when opening and closing the sliding door, this can lead to the cable twisting about its own axis.

Ein frühzeitiges Verschleißen oder Versagen der Verbindungsstellen des Seils mit den Endanschlüssen des Seils, die zum Ankoppeln des Seils an den Antrieb oder die Schiebetür dienen, kann die Folge sein. Bei Seilen aus einem verdrehten Drahtbündel oder Litzen kann es zusätzlich zu einem frühzeitigen Verschleiß oder Versagen des Seils selber kommen.Premature wear or failure of the cable connections to the cable end fittings used to couple the cable to the operator or sliding door can result. In the case of ropes made from a twisted bundle of wires or strands, premature wear or failure of the rope itself can also occur.

Aus beispielsweise der Druckschrift US 6,134,836 A ist es bekannt, zwei Umlenkrollen für das Seil einer Fahrzeugtürverstelleinheit vorzusehen, wobei die Umlenkachse der Umlenkrollen senkrecht zueinander orientiert sind. Aus der DE 603 15 402 T2 ist eine Fahrzeugtürverstelleinheit bekannt, die zwei Umlenkrollen in einem gemeinsamen Gehäuse aufweist.For example from the pamphlet US 6,134,836A it is known to provide two deflection rollers for the cable of a vehicle door adjustment unit, the deflection axes of the deflection rollers being oriented perpendicular to one another. From the DE 603 15 402 T2 a vehicle door adjustment unit is known which has two deflection rollers in a common housing.

Die vorgenannten, aus dem Stand der Technik bekannten Merkmale können einzeln oder in beliebiger Kombination mit einem der nachfolgend beschriebenen erfindungsgemäßen Gegenstände kombiniert werden.The aforementioned features known from the prior art can be combined individually or in any combination with one of the objects according to the invention described below.

Es ist Aufgabe der Erfindung, eine weiterentwickelte Fahrzeugtürverstelleinheit für eine Kraftfahrzeugschiebetür bereitzustellen.It is the object of the invention to provide a further developed vehicle door adjustment unit for a motor vehicle sliding door.

Zur Lösung der Aufgabe dient eine Fahrzeugtürverstelleinheit für eine Kraftfahrzeugschiebetür gemäß dem Hauptanspruch. Vorteilhafte Ausführungsformen ergeben sich aus den Unteransprüchen.A vehicle door adjustment unit for a motor vehicle sliding door according to the main claim serves to solve the task. Advantageous embodiments emerge from the dependent claims.

Die Aufgabe wird gelöst durch eine Fahrzeugtürverstelleinheit für eine Kraftfahrzeugschiebetür mit einer Umlenkeinrichtung zum Umlenken eines Seils für ein automatisches öffnen und/oder Schließen der Kraftfahrzeugschiebetür, wobei die Fahrzeugtürverstelleinheit das Seil sowie eine erste Umlenkrolle grundsätzlich zum Umlenken des Seils und eine zweite Umlenkrolle mit einem U-förmigen oder V-förmigen Seilaufnahmeprofil grundsätzlich zum Umlenken desselben Seils umfasst, wobei eine erste Umlenkachse der ersten Umlenkrolle und eine zweite Umlenkachse der zweite Umlenkrolle senkrecht oder im Wesentlichen senkrecht zueinander orientiert sind. Die erste Umlenkrolle und die zweite Umlenkrolle sind von einem gemeinsamen Gehäuse umschlossen, wobei das Gehäuse der Umlenkeinrichtung mit einem ersten Hohlraum für die erste Umlenkrolle und einem zweiten Hohlraum für die zweite Umlenkrolle ausgestattet ist, wobei der erste Hohlraum mit dem zweiten Hohlraum durch eine Durchgangsöffnung verbunden ist, deren maximale Öffnungsweite größer ist als der Seildurchmesser und optional geringer ist als das 1,5-fache der Dicke der ersten Umlenkrolle oder zweiten Umlenkrolle.The object is achieved by a vehicle door adjustment unit for a motor vehicle sliding door with a deflection device for deflecting a cable for automatic opening and/or closing of the motor vehicle sliding door, the vehicle door adjustment unit having the cable and a first deflection pulley basically for deflecting the cable and a second deflection pulley with a U shaped or V-shaped cable receiving profile basically comprises for deflecting the same cable, wherein a first deflection axis of the first deflection roller and a second deflection axis of the second deflection roller are oriented perpendicularly or essentially perpendicularly to one another. The first deflection roller and the second deflection roller are enclosed by a common housing, the housing of the deflection device being equipped with a first cavity for the first deflection roller and a second cavity for the second deflection roller, the first cavity being connected to the second cavity by a through-opening whose maximum opening width is greater than the rope diameter and optionally less than 1.5 times the thickness of the first pulley or second pulley.

Der Erfindung liegt die Erkenntnis zugrunde, dass ein Vorsehen einer senkrecht oder im Wesentlichen senkrecht hinter der ersten Umlenkrolle angeordnete zweite Umlenkrolle als Stopper für ein Verdrehen des Seils um seine eigene Achse wirken und so durch die oben angegebenen Merkmale der Erfindung einem Verdrehen um die eigene Achse effektive entgegenwirken werden kann.The invention is based on the finding that providing a second deflection roller arranged vertically or essentially vertically behind the first deflection roller acts as a stopper for twisting the rope about its own axis and thus prevents twisting about its own axis due to the features of the invention specified above can be counteracted effectively.

Ein Einbau der Umlenkeinrichtung in einen Durchgang von der Außenseite zur Innenseite der Kraftfahrzeugkarosserieseite kann so gleichzeitig den Bonuseffekt einer abdichtenden und schützenden Wirkung gegen äußere Einflüsse ermöglichen. Das Gehäuse für nur die erste Umlenkrolle wäre in der Regel nicht groß genug, um den Durchgang vollständig abzudecken.Installing the deflection device in a passage from the outside to the inside of the motor vehicle body side can thus simultaneously enable the bonus effect of a sealing and protective effect against external influences. The housing for just the first idler pulley would typically not be large enough to fully cover the passageway.

Ein besonders effektives Entgegenwirken kann mit dem U-förmigen oder V-förmigen Seilaufnahmeprofil der zweiten und/oder ersten Umlenkrolle ermöglicht werden. Im Wesentlichen senkrecht zueinander umfasst insbesondere einen Winkelbereich von ± 20°, vorzugsweise ± 15°, bevorzugt ± 10°, ganz besonders bevorzugt ± 5°.A particularly effective countermeasure can be made possible with the U-shaped or V-shaped cable receiving profile of the second and/or first deflection pulley. Substantially perpendicular to one another includes in particular an angular range of ±20°, preferably ±15°, preferably ±10°, very particularly preferably ±5°.

Erfindungsgemäß weisen die erste Umlenkachse und die zweite Umlenkachse einen Abstand zueinander auf, der kleiner ist als die Summe eines ersten Durchmessers oder Radius einer der Umlenkrollen und eines zweiten Radius der anderen der Umlenkrollen.According to the invention, the first deflection axis and the second deflection axis are at a distance from one another that is smaller than the sum of a first diameter or radius of one of the deflection rollers and a second radius of the other of the deflection rollers.

Der Abstand kann also kleiner als der Durchmesser der ersten und Radius der zweiten Umlenkrolle sein. Der Abstand kann auch kleiner als der Radius der ersten und Durchmesser der zweiten Umlenkrolle sein. Schließlich kann der Abstand kleiner als der Radius der ersten und zweiten Umlenkrolle sein. Ein besonders effektives Entgegenwirken gegen ein Verdrehen um die eigene Achse des Seils kann durch einen solch engen Abstand unterstützt werden.The distance can therefore be smaller than the diameter of the first and radius of the second deflection roller. The distance can also be smaller than the radius of the first and diameter of the second deflection roller. Finally, the distance can be smaller than the radius of the first and second deflection rollers. A particularly effective countermeasure against twisting about the rope's own axis can be supported by such a narrow distance.

In einer Ausführungsform weisen die erste Umlenkachse und die zweite Umlenkachse den oben angegebenen Abstand orthogonal zur ersten Umlenkachse und/oder orthogonal zur zweiten Umlenkachse auf. Der Abstand ist also entlang einer Geraden orthogonal zur ersten Umlenkachse oder orthogonal zur zweiten Umlenkachse zu messen. Ebenfalls vorteilhaft ist es den Abstand auf einer gemeinsamen Gerade zu messen, die sowohl orthogonal auf der ersten und zweiten Umlenkachse steht. Ein besonders effektives Entgegenwirken gegen ein Verdrehen um die eigene Achse des Seils kann durch einen derart orientiert gemessenen Abstand unterstützt werden.In one embodiment, the first deflection axis and the second deflection axis have the above-specified distance orthogonally to the first deflection axis and/or orthogonally to the second deflection axis. The distance is therefore to be measured along a straight line orthogonal to the first deflection axis or orthogonal to the second deflection axis. It is also advantageous to measure the distance on a common straight line that is orthogonal to the first and second deflection axis. A particularly effective countermeasure against twisting about the rope's own axis can be supported by a distance measured in such an oriented manner.

In einer Ausführungsform entspricht der Abstand mindestens dem ersten Radius der ersten Umlenkrolle oder dem zweiten Radius der zweiten Umlenkrolle. Ein besonders zuverlässiger Betrieb und saubere Führung des Seils in den Umlenkrollen kann so ermöglicht werden.In one embodiment, the distance corresponds at least to the first radius of the first deflection roller or to the second radius of the second deflection roller. A particularly reliable operation and clean guidance of the cable in the deflection pulleys can be made possible.

Insbesondere kann auch der Abstand zwischen den Schnittpunkten der Umlenkrollen mit den jeweiligen Umlenkachsen gemessen werden.In particular, the distance between the intersection points of the deflection rollers with the respective deflection axes can also be measured.

In einer Ausführungsform verläuft das Seil von der ersten Umlenkrolle unmittelbar zu der zweiten Umlenkrolle.In one embodiment, the cable runs from the first deflection pulley directly to the second deflection pulley.

Von der ersten Umlenkrolle zu der zweiten Umlenkrolle verlaufen meint, dass das Seil von der ersten Umlenkrolle und der zweiten Umlenkrolle nacheinander umgelenkt wird. Unmittelbar von der ersten Umlenkrolle zu der zweiten Umlenkrolle verlaufen meint, dass zwischen der ersten Umlenkrolle und der zweiten Umlenkrolle keine weitere Umlenkrolle oder sonst ein Umlenkmittel angeordnet ist und auf das Seil einwirkt.Running from the first deflection pulley to the second deflection pulley means that the cable is deflected successively by the first deflection pulley and the second deflection pulley. Running directly from the first deflection roller to the second deflection roller means that no further deflection roller or other deflection means is arranged between the first deflection roller and the second deflection roller and acts on the cable.

Das Seil verläuft also direkt von der ersten Umlenkrolle zur zweiten Umlenkrolle, wobei "verlaufen" die geometrische Erstreckung und nicht eine Vorschubbewegung meint.The rope thus runs directly from the first deflection pulley to the second deflection pulley, with "running" meaning the geometric extension and not a feed movement.

Ein besonders effektives Entgegenwirken gegen ein Verdrehen um die eigene Achse des Seils kann so unterstützt werden.A particularly effective countermeasure against twisting around the own axis of the rope can be supported in this way.

In einer Ausführungsform verläuft das Seil tangential zur ersten Umlenkrolle und tangential zur zweiten Umlenkrolle. Wenn das Seil eine Linie ohne Durchmesser wäre, würden die erste und die zweite Umlenkrolle eine gemeinsame Tangentiale aufweisen. Die Tangente und das Seil liegen dann an grundsätzlich 90° oder im Wesentlichen 90° versetzten Punkten an der ersten und zweiten Umlenkrolle - oder genauer gesagt insbesondere im Tal eines U-förmigen Seilaufnahmeprofils - auf. Ein besonders effektives Entgegenwirken gegen ein Verdrehen um die eigene Achse des Seils kann so unterstützt werden.In one embodiment, the cable runs tangentially to the first pulley and tangentially to the second pulley. If the rope were a line with no diameter, the first and second pulleys would share a common tangent. The tangent and the cable then rest at points on the first and second deflection rollers that are essentially offset by 90° or essentially 90°—or, to be more precise, in particular in the valley of a U-shaped cable receiving profile. A particularly effective countermeasure against twisting around the own axis of the rope can be supported in this way.

In einer Ausführungsform ist das Seil zwischen der ersten und zweiten Umlenkrolle gespannt. Gespannt meint im Wesentlichen geradlinig verlaufend. Grundsätzlich weicht der Verlauf eines gespannten Seils im Betrieb nicht mehr als 1 mm, bevorzugt 0,5 mm, von einer Geraden ab oder hängt um diesen Betrag durch. Für eine hinreichend große Zugkraft und/oder kleine Seillänge ist also grundsätzlich gesorgt. In dem Abschnitt des Seils zwischen der ersten und zweiten Umlenkrolle berührt das Seil sonst keine anderen Bauteile. Allenfalls eine unplanmäßige Berührung mit einem Gehäuse oder einem anderen das Seil umgebenden Schutzmittel ist möglich, insbesondere bei einem Durchhängen des Seils. Durch den gespannten Zustand zwischen der ersten und zweiten Umlenkrolle wird ein Schleifen an einer anderen Oberfläche und somit Verschleiß vermieden.In one embodiment, the cable is tensioned between the first and second deflection pulleys. Tensioned essentially means running in a straight line. In principle, the course of a tensioned rope during operation does not deviate by more than 1 mm, preferably 0.5 mm, from a straight line or sags by this amount. A sufficiently large pulling force and/or short cable length is therefore always ensured. In the section of the cable between the first and second deflection rollers, the cable otherwise does not touch any other components. At most, unintentional contact with a housing or other means of protection surrounding the rope is possible, especially if the rope sags. Due to the tense state between the first and second deflection roller, grinding on another surface and thus wear is avoided.

Durch die höheren Reibeffekte kann so zudem zu einem Entgegenwirken gegen ein Verdrehen des Seils um die eigene Achse beigetragen werden.The higher friction effects can also contribute to counteracting the rope twisting around its own axis.

In einer Ausführungsform ist die Umlenkeinrichtung so beschaffen, dass das Seil durch die erste Umlenkrolle um mindestens 90°, bevorzugt 135°, besonders bevorzugt genau oder im Wesentlichen 180° umgelenkt wird.In one embodiment, the deflection device is designed in such a way that the rope is deflected by the first deflection pulley by at least 90°, preferably 135°, particularly preferably exactly or essentially 180°.

Um einen Winkel umlenken meint, den Winkel von einem zur Umlenkrolle verlaufenden Seilabschnitt zu einem von der Umlenkrolle weglaufenden Seilabschnitt, umzulenken. Ein Umlenkwinkel von 180° bedeutet daher eine vollständige Richtungsumkehr.Deflecting by an angle means deflecting the angle from a cable section running to the deflection pulley to a cable section running away from the deflection pulley. A deflection angle of 180° therefore means a complete reversal of direction.

Ein besonders effektives Entgegenwirken gegen ein Verdrehen um die eigene Achse des Seils kann so unterstützt werden.A particularly effective countermeasure against twisting around the own axis of the rope can be supported in this way.

In einer Ausführungsform ist die Umlenkeinrichtung so beschaffen, dass das Seil durch die zweite Umlenkrolle um mindestens 15°, bevorzugt 30°, und/oder höchstens 135°, bevorzugt 90°; umgelenkt wird.In one embodiment, the deflection device is designed in such a way that the cable is guided through the second deflection pulley by at least 15°, preferably 30°, and/or at most 135°, preferably 90°; is deflected.

Ein besonders effektives Entgegenwirken gegen ein Verdrehen um die eigene Achse des Seils kann so unterstützt werden.A particularly effective countermeasure against twisting around the own axis of the rope can be supported in this way.

Dicke meint Erstreckung in Umlenkachsrichtung.Thickness means extension in the direction of the deflection axis.

Durch eine in oben beschriebener Weise enge Durchgangsöffnung kann ein besonders hoher Abdichtungseffekt ermöglicht werden.A particularly high sealing effect can be made possible by a through-opening which is narrow in the manner described above.

In einer Ausführungsform ist ein Führungsmittel, insbesondere Hülle, zum Führen und Schützen des Seils vor oder hinter der Umlenkeinrichtung vorgesehen. Mit Hülle ist insbesondere eine schlauchförmige Hülle gemeint.In one embodiment, a guide means, in particular a cover, is provided for guiding and protecting the cable in front of or behind the deflection device. Cover means in particular a tubular cover.

Vor oder hinter der Umlenkeinrichtung meint, dass Führungsmittel von der ersten Umlenkrolle aus gesehen hinter der zweiten Umlenkrolle und/oder umgekehrt angeordnet sind.In front of or behind the deflection device means that guide means are arranged behind the second deflection roller and/or vice versa, as seen from the first deflection roller.

Ein besonders hoher Schutz des Seils und ein variabler Verlauf des Weges zum Anschlusspunkt an der Schiebetür oder dem Antrieb kann so ermöglicht werden.A particularly high protection of the cable and a variable course of the path to the connection point on the sliding door or the drive can be made possible.

In einer Ausführungsform ist das Führungsmittel fest mit einem Gehäuse der ersten Umlenkrolle und/oder zweiten Umlenkrolle verbunden. Ein glatter und abriebverschleißarmer Übergang zwischen dem Gehäuse oder der insbesondere zweiten Umlenkrolle zum Führungsmittel, insbesondere Hülle, kann so ermöglicht werden.In one embodiment, the guide means is firmly connected to a housing of the first deflection roller and/or second deflection roller. A smooth and low-abrasion transition between the housing or the in particular second deflection roller to the guide means, in particular the casing, can thus be made possible.

Darüber hinaus eröffnet das Vorsehen einer festen Ankopplung die Nutzung des Seils und der Hülle als Bowdenzug.In addition, the provision of a fixed coupling opens up the use of the rope and the sheath as a Bowden cable.

In einer Ausführungsform ist das Führungsmittel eine bowdenzugartige Hülle und/oder die Hülle und das Seil bilden einen Bowdenzug, grundsätzlich mit kraftschlüssiger und/oder formschlüssiger Kopplung der Hülle am Gehäuse der Umlenkeinrichtung und mit der anderen Seite am Gehäuse des Antriebs. Die Kopplung kann durch seitliches Aufschieben erfolgen, beispielsweise mit einer schwalbenschwanzartigen Verbindung oder einer Schwalbenschwanzverbindung.In one embodiment, the guide means is a Bowden cable-like sleeve and/or the sleeve and the cable form a Bowden cable, basically with a non-positive and/or positive coupling of the sleeve on the housing of the deflection device and with the other side on the housing of the drive. The coupling can be done by sliding it on to the side, for example with a dovetail-like connection or a dovetail connection.

Bowdenzugartige Hülle meint eine schlauchförmige Ummantelung des Seils, welche Druckkräfte und Zugkräfte übertragen kann. Das Vorsehen eines Bowdenzugs mit der Hülle und dem Seil ermöglicht ein automatisches Öffnenund Schließen der Kraftfahrzeugschiebetür durch den Antrieb.Bowden cable-like sheath means a tubular sheathing of the rope, which can transmit compressive and tensile forces. The provision of a Bowden cable with the sleeve and the cable enables the motor vehicle sliding door to be opened and closed automatically by the drive.

In einer Ausführungsform weisen die erste Umlenkrolle und die zweite Umlenkrolle einen gleichen Durchmesser auf und/oder sind baugleich.In one embodiment, the first deflection roller and the second deflection roller have the same diameter and/or are identical in construction.

Eine Fahrzeugtürverstelleinheit kann auf diese Weise mit besonderes wenig verschiedenen Teilen und geringem Aufwand hergestellt werden.A vehicle door adjustment unit can be manufactured in this way with a particularly small number of different parts and with little effort.

Nachfolgend werden Ausführungsbeispiele der Erfindung anhand von Figuren näher erläutert. Merkmale der Ausführungsbeispiele können einzeln oder in einer Mehrzahl mit dem beanspruchten Gegenstand kombiniert werden.Exemplary embodiments of the invention are explained in more detail below with reference to figures.

Die Figur 1 zeigt eine wandartige Kraftfahrzeugkarosserieseite von innen, in welche eine Vielzahl von Komponenten 7, von denen Figur 1 nur zwei davon wie z.B. ein Lautsprecher oder Elektronikbauteil exemplarisch und schematisch darstellt, integriert sind.the figure 1 shows a wall-like motor vehicle body side from the inside, in which a variety of components 7, of which figure 1 only two of them, such as a loudspeaker or electronic component, are integrated as an example and diagrammatically.

Eine Kraftfahrzeugschiebetür ist seitlich an der Außenseite der wandartigen Kraftfahrzeugkarosserieseite bzw. des Fahrzeugs längs einer Führungsschiene 11 (in Figur 1 verdeckt und durch eine gestrichelte Linien dargestellt) translatorisch verschiebbar angebracht, so dass die Schiebetür in Längsrichtung vor und zurück für ein Öffnenund Schließen geschoben werden kann.A motor vehicle sliding door is laterally mounted on the outside of the wall-like motor vehicle body side or the vehicle along a guide rail 11 (in figure 1 hidden and represented by a dashed line) mounted translationally so that the sliding door can be slid longitudinally back and forth for opening and closing.

Für ein automatisches Öffnen - vorzugsweise auch Schließen - der Kraftfahrzugschiebetür ist eine Fahrzeugtürverstelleinheit mit einem Antrieb 10 vorgesehen. Der Antrieb 10 ist vorliegend nicht an der Schiebetür, sondern fest an einer dafür vorgesehenen Stelle der Kraftfahrzeugkarosserie neben den anderen Komponenten 7 angebracht.A vehicle door adjustment unit with a drive 10 is provided for automatic opening—preferably also closing—of the motor vehicle sliding door. In the present case, the drive 10 is not attached to the sliding door, but fixedly attached to a location provided for this purpose on the motor vehicle body next to the other components 7 .

In einer geöffneten Stellung der Kraftfahrzeugschiebetür befindet sich die Schiebetür hinter der Ansicht der Figur 1 .In an open position of the motor vehicle sliding door, the sliding door is behind the view figure 1 .

Ein Seil 1, welches die Schiebetür durch den Antrieb 10 von der geöffneten Stellung zur geschlossenen Stellung, also zur linken Seite in der Ansicht der Figur 1, bewegen kann, ist mit einem Ende mit dem Antrieb 10 und mit dem anderen Ende an der Schiebetür verbunden.A cable 1, which the sliding door through the drive 10 from the open position to the closed position, ie to the left in the view of figure 1 , can move is connected to the drive 10 at one end and to the sliding door at the other end.

Von dem ersten Ende des Seils 1, das mittels eines Seilendanschlusses mit der Schiebetür verbunden oder gekoppelt ist, verläuft das Seil 1 über einen äußeren Seilwegabschnitt 12 vorzugsweise auf Höhe der Führungsschiene 11, insbesondere mittig dazu, an der Außenseite der Kraftfahrzeugkarosserieseite entlang bis zu einem Durchgang 15 von der Außenseite zur Innenseite der Kraftfahrzeugkarosserieseite.From the first end of the cable 1, which is connected or coupled to the sliding door by means of a cable end connection, the cable 1 runs via an outer cable path section 12, preferably at the level of the guide rail 11, in particular centrally thereto, along the outside of the motor vehicle body side to a passage 15 from the outside to the inside of the automobile body side.

In diesem Durchgang 15 ist die erste Umlenkrolle 3 drehbar an einer vertikalen ersten Umlenkachse 6 gelagert, um das Seil 1 U-förmig um die wandartige Kraftfahrzeugkarosserieseite umzulenken.In this passage 15, the first deflection roller 3 is rotatably mounted on a vertical first deflection axis 6 in order to deflect the cable 1 in a U-shape around the wall-like side of the motor vehicle body.

Von der ersten Umlenkrolle 3 verläuft das Seil 1 direkt zu einer zweiten Umlenkrolle 4, die an einer horizontalen und orthogonal auf der Kraftfahrzeugkarosserieseite stehenden zweiten Umlenkachse 8 drehbar gelagert ist. Ein zwischen der ersten und zweiten Umlenkrolle 3, 4 zwischenliegender Seilwegabschnitt erstreckt sich entlang einer gemeinsamen Tangentiale 13 zur ersten und zweiten Umlenkrolle 3, 4, derart, dass das Seil 1 nach dem Lösen von der ersten Umlenkrolle 3 bei geradlinig gespannten Zustand parallel zur Führungsschiene 11 und parallel zur Kraftfahrzeugkarosserieseite auf der zweiten Umlenkrolle 4 aufsetzt.The cable 1 runs from the first deflection pulley 3 directly to a second deflection pulley 4 which is rotatably mounted on a second deflection axis 8 which is horizontal and orthogonal to the motor vehicle body side. A cable path section between the first and second deflection pulleys 3, 4 extends along a common tangential line 13 to the first and second deflection pulleys 3, 4 in such a way that the cable 1, after being released from the first deflection pulley 3 in a straight-line tensioned state, runs parallel to the guide rail 11 and parallel to the motor vehicle body side on the second deflection roller 4 touches down.

Nach dem Lösen von der zweiten Umlenkrolle 4 schließt sich ein innerer Seilwegabschnitt an, der geschwungen, also insbesondere zum Teil spiralförmig oder geschlängelt, an den Komponenten 7 vorbei bis zum Antrieb 10 verläuft. Zum Teil oder vollständig ist das Seil 1 auf dem inneren Seilwegabschnitt durch eine Hülle 9 geschützt und an den Komponenten 7 in oben beschriebener Weise vorbei geführt.After detachment from the second deflection roller 4 , an inner cable path section follows, which runs in a curved manner, that is to say in particular in part in a spiral or meandering manner, past the components 7 to the drive 10 . The rope 1 is partially or completely protected on the inner section of the rope path by a sheath 9 and guided past the components 7 in the manner described above.

Zum Schließen der Kraftfahrzeugschiebetür wird nun das Seil 1 durch den Antrieb 10 zum Antrieb 10 hin gezogen. Das Seil 1 bewegt sich also unter Spannung eine Strecke mit der Länge des Translationsweges von der Schiebetür von der geöffneten Stellung in die geschlossene Stellung von der Kraftfahrzeugschiebetür um die erste Umlenkrolle 3 herum und durch die zweite Umlenkrolle 4 in seiner Richtung abgelenkt durch die Hülle 9 in Richtung Antrieb 10.To close the motor vehicle sliding door, the cable 1 is now pulled through the drive 10 towards the drive 10 . The cable 1 thus moves under tension a distance with the length of the translation path from the sliding door from the open position to the closed position from the motor vehicle sliding door around the first deflection roller 3 and deflected by the second deflection roller 4 in its direction through the sheath 9 in Drive direction 10.

Der Antrieb 10 erfasst vorteilhafterweise zumindest zwei Rollen, wobei auf einer ersten Rolle ein erstes Seil 1 während des Schließens aufgewickelt wird und von einer zweite Rolle ein zweites Seil abgewickelt wird. Das zweite Seil ist mit einem Ende an der Schiebetür und mit einem anderen Ende mit dem Antrieb 10 verbunden.The drive 10 advantageously includes at least two rollers, a first rope 1 being wound up on a first roller during closing and a second rope being unwound from a second roller. The second cable is connected to the sliding door at one end and to the drive 10 at another end.

Wird die Tür geöffnet, wird das zweite Seil über eine zweite nicht dargestellte Umlenkeinrichtung geführt. Das zweite Seil wird durch den Antrieb 10 zum Antrieb hin gezogen, so dass das Öffnen der Tür veranlasst wird. Das zweite Seil wird entsprechend auf der zweiten Rolle innerhalb des Antriebs 10 aufgewickelt und das erste Seil 1 wird zeitgleich auf der ersten Rolle abgewickelt.If the door is opened, the second cable is guided over a second deflection device, not shown. The second cable is pulled towards the drive by the drive 10, causing the door to open. The second cable is accordingly wound up on the second pulley within the drive 10 and the first cable 1 is unwound on the first pulley at the same time.

Verdrehungen um die eigene Achse des Seils 1 innerhalb der Hülle 9 auf dem inneren Seilwegabschnitt werden durch die im Wesentlichen senkrecht zur ersten Umlenkrolle 3 orientierten zweiten Umlenkrolle 4 an einem Ausbreiten zur ersten Umlenkrolle 3 wirksam gehindert. Es versteht sich, dass Entsprechendes auch für die zweite nicht dargestellte Umlenkeinrichtung gilt.Twisting about the own axis of the rope 1 within the sheath 9 on the inner section of the rope path is effectively prevented from spreading to the first deflection roller 3 by the second deflection roller 4 oriented essentially perpendicularly to the first deflection roller 3 . It goes without saying that the same also applies to the second deflection device, which is not shown.

Vorteilhafterweise ist die Umlenkeinrichtung 2 derart gewählt, dass diese eine Dichtungskraft zu überwinden vermag. Es ist auch denkbar ein Schließen der Kraftfahrzeugschiebetür bis zu einer Vorrastposition zu veranlassen, so dass eine nicht dargestellte Zuziehhilfe die Tür gegen die Dichtungskraft in die geschlossene Position bringt.Advantageously, the deflection device 2 is selected in such a way that it is able to overcome a sealing force. It is also conceivable to cause the motor vehicle sliding door to be closed up to a pre-locking position, so that a closing aid (not shown) brings the door into the closed position against the sealing force.

Figur 2 zeigt das Innere der Umlenkeinrichtung 2 mit der ersten Umlenkrolle 3 und zweiten Umlenkrolle 4, die in einer Ausführungsform baugleich sind. figure 2 shows the interior of the deflection device 2 with the first deflection roller 3 and second deflection roller 4, which are identical in one embodiment.

Die erste und zweite Umlenkrolle 3, 4 sind scheibenförmig oder haben eine scheibenartige Form. An der Umfangsfläche weisen die Umlenkrollen 3, 4 ein Seilaufnahmeprofil auf, das vorzugsweise U-förmig oder V-förmig ist. Das Seil 1 liegt vorzugsweise mittig im Tal der U-Form oder mittig in der V-Form auf. Insbesondere ist das Seilaufnahmeprofil der ersten Umlenkrolle 3 und/oder zweiten Umlenkrolle 4 an den Seildurchmesser angepasst, derart, dass das Seil 1 flächige auf der Umlenkrolle 3, 4 aufliegen kann. Eine besonders große Haftreibung kann so erzielt werden.The first and second guide rollers 3, 4 are disk-shaped or have a disk-like shape. On the peripheral surface, the deflection rollers 3, 4 have a cable receiving profile which is preferably U-shaped or V-shaped. The rope 1 is preferably centered in the valley of the U-shape or centered in the V-shape. In particular, the rope receiving profile of the first deflection roller 3 and/or second deflection roller 4 is adapted to the rope diameter in such a way that the rope 1 can lie flat on the deflection roller 3, 4. A particularly high static friction can be achieved in this way.

Die erste Umlenkrolle 3 und die zweite Umlenkrolle 4 sind so zueinander angeordnet, dass beide Umlenkrollen 3, 4 eine gemeinsame Tangentiale 13 haben. Diese Tangentiale 13 hat im Sinne der vorliegenden Anmeldung den Durchmesser des Seils 1, so dass auch ein parallel zur Führungsschiene 11 und mittig im Tal der ersten und zweiten Umlenkrolle 3, 4 aufliegend verlaufendes Seil 1 als tangential zur ersten Umlenkrolle 3 und zweiten Umlenkrolle 4 beschrieben werden kann, obgleich beide Umlenkrollen 3, 4 senkrecht und versetzt zueinander orientiert sind.The first deflection roller 3 and the second deflection roller 4 are arranged relative to one another in such a way that both deflection rollers 3, 4 have a common tangential line 13. In the sense of the present application, this tangential 13 has the diameter of the cable 1, so that a cable 1 running parallel to the guide rail 11 and lying centrally in the valley of the first and second deflection rollers 3, 4 is also described as tangential to the first deflection roller 3 and second deflection roller 4 can be, although both deflection rollers 3, 4 are oriented perpendicular and offset to each other.

Denn in Wirklichkeit erstreckt sich eine erste Tangentiale zentriert im Tal auf dem sich entlang des Umfangs erstreckenden Seilaufnahmeprofil der ersten Umlenkrolle 3 genau parallel in einem Abstand entsprechend dem Seildurchmesser zu einer zweiten Tangentiale zentriert im Tal auf dem sich entlang des Umfangs erstreckenden Seilaufnahmeprofil der zweiten Umlenkrolle 4. Auf diese Weise kann das Seil 1 parallel zur Führungsschiene 11 zwischen der ersten und zweiten Umlenkrolle 3, 4 gespannt werden. Für eine vereinfachte Beschreibung mit einer nur geringen Abweichung wurde oben lediglich von einer gemeinsamen Tangentiale 13 der ersten und zweiten Umlenkrolle 3, 4 gesprochen.In reality, a first tangential line extends centered in the valley on the circumferentially extending rope receiving profile of the first deflection roller 3 exactly parallel at a distance corresponding to the rope diameter to a second tangential centered in the valley on the circumferentially extending rope receiving profile of the second deflection roller 4 In this way, the cable 1 can be tensioned parallel to the guide rail 11 between the first and second deflection rollers 3, 4. For a simplified description with only a small deviation, only a common tangential 13 of the first and second deflection rollers 3, 4 was mentioned above.

Wie Figur 2 zeigt, weisen die erste Umlenkachse 6 und die zweite Umlenkachse 8 einen Abstand 5 orthogonal zur ersten Umlenkachse 6 und orthogonal zur zweiten Umlenkachse 8 zueinander auf, der größer ist als der erste Radius der ersten Umlenkrolle 3 und kleiner ist als die Summe des ersten Radius der ersten Umlenkrolle 3 und des zweiten Radius der zweiten Umlenkrolle 4. Insbesondere beträgt der Abstand 5 im Wesentlichen der Summe aus dem ersten Radius und dem halben zweiten Radius. Ein besonders kurzer Abstand 5 und damit ein besonders effektives Stoppen eines Verdrehens des Seils 1 um die eigene Achse kann so ermöglicht werden.As figure 2 shows, the first deflection axis 6 and the second deflection axis 8 have a distance 5 orthogonal to the first deflection axis 6 and orthogonal to the second deflection axis 8 to one another, which is greater than the first radius of the first deflection roller 3 and smaller than the sum of the first radius of the first deflection roller 3 and the second radius of the second deflection roller 4. In particular, the distance 5 is essentially the sum of the first radius and half the second radius. A particularly short distance 5 and thus a particularly effective stopping of twisting of the cable 1 about its own axis can thus be made possible.

Die Figur 2 zeigt ein Koordinatensystem mit den Koordinatenachsen x, y und z an, wobei die x-Achse längs des Fahrzeugs, also längs der Fahrzeugkarosserieseite und somit auch längs der Führungsschiene 11 verläuft. Die y-Achse erstreckt sich orthogonal dazu, also parallel zur zweiten Umlenkachse 8. Die z-Achse steht orthogonal auf der x-Achse und y-Achse.the figure 2 shows a coordinate system with the coordinate axes x, y and z, the x-axis running along the vehicle, ie along the side of the vehicle body and thus also along the guide rail 11 . The y-axis extends orthogonally thereto, ie parallel to the second deflection axis 8. The z-axis is orthogonal to the x-axis and y-axis.

Das Seil 1 wird durch die erste Umlenkrolle 3 um 180° und anschließend durch die zweite Umlenkrolle 4 um 30° umgelenkt (Figur 2).The cable 1 is deflected by 180° by the first deflection pulley 3 and then by 30° by the second deflection pulley 4 ( figure 2 ).

In Figur 2 wird das Seil 1 vom äußeren Seilwegabschnitt 12 aus unter einem Einlaufwinkel 15 von 90° zur y-Achse von der ersten Umlaufrolle 3 aufgenommen. Der Auslaufwinkel 16 des inneren Seilwegabschnitts 14 zur x-Achse oder zur Tangentialen 13 beträgt 30° in Figur 2. Ein besonders effektives Hemmen oder Unterbinden einer Ausbreitung eines Verdrehens des Seils 1 um seine eigene Achse kann so erzielt werden.In figure 2 the rope 1 is taken up by the first revolving roller 3 from the outer rope path section 12 at an infeed angle 15 of 90° to the y-axis. The run-out angle 16 of the inner cable path section 14 to the x-axis or to the tangential 13 is 30° in figure 2 . A particularly effective inhibition or suppression of a propagation of a twisting of the cable 1 about its own axis can be achieved in this way.

Zur Verbindung des Seils 1 mit der Schiebetür und/oder dem Antrieb sind unterschiedliche Ausführungen von Seilendanschlüssen und deren Verbindung zum Seil 1 möglich. In einer Ausführungsform ist ein Seilendanschluss als ein am Ende des Seils angelöteter oder angepresster Nippel in Birnen-, Kugel- oder Tonnenform ausgestaltet. In einer weiteren Ausführungsform hat der Seilendanschluss die Form einer Öse, eines Hakens, eines Gewindebolzens oder eines Knopfes. In einer weiteren Ausführungsform ist ein Seilendanschluss mit einem Justiermittel für ein Spannen des Seils 1 vorgesehen. Die Verbindung des Seilendanschlusses zum Seil 1 kann durch Verpressen, Verlöten oder Schrauben realisiert sein.To connect the cable 1 to the sliding door and/or the drive, different designs of cable end connections and their connection to the cable 1 are possible. In one embodiment, a cable end connection is designed as a pear-shaped, ball-shaped or barrel-shaped nipple that is soldered or pressed onto the end of the cable. In a further embodiment, the cable end connection is in the form of an eyelet, a hook, a threaded bolt or a button. In a further embodiment, a rope end connection is provided with an adjustment means for tensioning the rope 1 . The connection of the rope end connection to the rope 1 can be realized by pressing, soldering or screwing.

In einer Ausführungsform umfasst das Seil ein verdrehtes Drahtbündel oder verdrehte Litzen, um mit besonders geringem Aufwand ein äußerst zugfestes Seil 1 bereitstellen zu können.In one embodiment, the cable comprises a twisted bundle of wires or twisted strands in order to be able to provide a cable 1 with extremely high tensile strength with particularly little effort.

In einer Ausführungsform ist die Hülle 9 schlauchförmig und/oder erlaubt eine flexible Richtungsänderung beim Verlegen. Das Seil 1 kann so besonders platzsparend verlegt werden.In one embodiment, the sleeve 9 is tubular and/or allows a flexible change of direction when laying. The rope 1 can thus be laid in a particularly space-saving manner.

In einer Ausführungsform bilden das Seil 1 und die Hülle 9 einen Bowdenzug. Ein Öffnen und Schließen der Kraftfahrzeugschiebetür durch den Antrieb kann so ermöglicht werden.In one embodiment, the cable 1 and the sheath 9 form a Bowden cable. The motor vehicle sliding door can thus be opened and closed by the drive.

Die Figuren 3 und 4 zeigen den Aufbau des Gehäuses 17 (in Figur 1 ausgeblendet) der Umlenkeinrichtung 2 mit einem ersten Hohlraum 18 für die erste Umlenkrolle 3, der durch eine Durchgangsöffnung 20 mit einem zweiten Hohlraum 19 für die zweite Umlenkrolle 4 verbunden ist. Die Hohlräume 18, 19 sind so an die Umlenkrollen 3, 4 angepasst, dass die Umlenkrollen 3, 4 überwiegend oder vollständig von dem Gehäuse 17 umschlossen werden und/oder nur einen engen Spalt zu einer Innenoberfläche des Gehäuses 17, also den Oberflächen eines Hohlraums 18, 19 aufweisen. Auf diese Weise werden nicht nur die Umlenkrollen 3, 4 vor Verschmutzung und anderen die Lebensdauer verkürzenden Einflüssen geschützt werden, sondern die Umlenkeinrichtung 2 kann gleichzeitig dazu genutzt werden, auch das Innere der Karosserie vor den äußeren Umwelteinflüssen zu schützen und gewissermaßen einen abdichtenden Effekt gegenüber Feuchtigkeit und ähnlichen Einflüssen zu erzielen. Die Umlenkeinrichtung 2 ist zu diesem Zweck in einer Ausführungsform innerhalb des Durchgangs 15 oder den Durchgang 15 zum Teil oder vollständig abdeckend angebracht.the Figures 3 and 4 show the construction of the housing 17 (in figure 1 hidden) of the deflection device 2 with a first cavity 18 for the first deflection roller 3, through a through-opening 20 with a second cavity 19 for the second Deflection roller 4 is connected. The cavities 18, 19 are adapted to the deflection rollers 3, 4 in such a way that the deflection rollers 3, 4 are predominantly or completely enclosed by the housing 17 and/or only have a narrow gap to an inner surface of the housing 17, i.e. the surfaces of a cavity 18 , 19 have. In this way, not only are the deflection rollers 3, 4 protected from dirt and other influences that shorten the service life, but the deflection device 2 can also be used at the same time to protect the interior of the body from external environmental influences and, to a certain extent, to have a sealing effect against moisture and similar influences. For this purpose, in one embodiment, the deflection device 2 is fitted inside the passage 15 or partially or completely covering the passage 15 .

Das Seil 1 passiert eine Durchgangsöffnung 20 mit den Abmessungen in x-Richtung und z-Richtung von im Wesentlichen der Dicke, also Erstreckung in Umlenkachsrichtung, der Scheibenform der ersten Umlenkrolle 3. Durch diese vergleichsweise enge Durchgangsöffnung 20 und den zickzackartigen, geschlängelten Verlauf der Hohlräume 18, 19 nebst Verbindung durch die Durchgangsöffnung 20 kann dem Eindringen von äußeren Stoffen ins Innere der Karosserie effizient entgegengewirkt werden.The rope 1 passes through a through-opening 20 with the dimensions in the x-direction and z-direction of essentially the thickness, i.e. extension in the direction of the deflection axis, the disk shape of the first deflection roller 3. Through this comparatively narrow through-opening 20 and the zigzag-like, meandering course of the cavities 18, 19 together with the connection through the through-opening 20, the penetration of external substances into the interior of the body can be counteracted efficiently.
