Description

Fensterhebeeinrichtung Window lifter
Die Erfindung betrifft eine Fensterhebeeinrichtung, insbeson¬ dere für eine Kraftfahrzeugtür, mit einem Fensterheber, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a window lifting device, in particular for a motor vehicle door, with a window, according to the preamble of claim 1.
Im modernen Kraftfahrzeugbau sind die manuell zu bedienenden Fensterheber häufig durch Fensterhebeeinrichtungen, insbeson¬ dere mit einem elektrischen Antrieb, ersetzt. Dabei wirkt der beispielsweise elektrische Fensterheber über ein Verbindungs¬ glied, beispielsweise ein Zugseil, auf einen Mitnehmer ein, an welchem die zu öffnende bzw. die zu schließende Fenster¬ scheibe angeordnet ist. Ein Durchtrennen des Verbindungs¬ glieds, also beispielsweise des Zugseils, hat zur Folge, dass die Fensterscheibe einerseits nicht mehr von der Fensterhebe¬ einrichtung verstellt werden kann, andererseits aber händisch leicht durch ein Verschieben zu öffnen bzw. zu schließen ist.In modern motor vehicle engineering, the manually operated window regulators are frequently replaced by window lifting devices, in particular with an electric drive. In this case, for example, the electric window lifter acts via a connecting member, for example a pulling cable, on a driver on which the window pane to be opened or to be closed is arranged. A severing of the Verbindungs¬ member, so for example the pull rope, has the consequence that the window pane on the one hand no longer can be adjusted by the Fensterhebe¬ device, but on the other hand manually by opening or closing is easy to close.
Aus der DE 28 12 314 C3 ist ein Fensterheber für ein schieb¬ bares, insbesondere in den Fensterschacht eines Kraftfahr¬ zeugs versenkbares Fenster, bekannt. Der Fensterheber weist ein zug- und drucksteif in einem Führungsrohr verschiebbares und unmittelbar oder mittelbar am Fenster angeschlossenes Ge¬ windekabel auf, mit dem in einem zweigeteilten, aus Kunst¬ stoff gespritzten Antriebsgehäuse das mit einer in beiden Ge¬ häuseteilen gelagerten Antriebswelle drehfest verbundene An- triebsritzel eines mit Schleppfederbremse ausgestatteten Zahnradantriebs im Eingriff steht. Eine Teilungsebene der beiden Gehäuseteile des Antriebsgehäuses befindet sich dabei außerhalb des durch das Gehäuse geführten Gewindekabeis und des Antriebsritzels zwischen diesem und der Schleppfederbrem¬ se. Die Teilungsebene tangiert desweiteren den Außenumfang des Gewindekabels, so dass der das Gewindekabel führende und zum Antriebsritzel sowie zur Teilungsebene hin geöffnete Füh¬ rungskanal in dem einen Gehäuseteil eingeformt ist. Hierdurch wird der Achsabstand zwischen dem Antriebsritzel und dem Ge¬ windekabel durch die von der Spritzform vorgegebene definier¬ te Lage des Führungskanals in dem einen Gehäuseteil stets ex¬ akt eingehalten. Die erwähnte Lage der Gehäuseteilungsebene sorgt dafür, dass die beiden Gehäuseteile nicht durch den in Folge des Zahneingriffs bewirkten Anpressdruck auf das Kabel auseinander gedrängt werden. Das Gewindekabel verläuft dabei innerhalb des Führungsrohres, welches im Innern einer Fahr¬ zeugtür angeordnet ist.From DE 28 12 314 C3 a window regulator for a schieb¬ bares, in particular in the window slot of a motor vehicle retractable window known. The window lifter has a tension cable which is displaceable in a guide tube and which is directly or indirectly connected to the window, with which the drive shaft rotatably connected to a drive shaft mounted in both housing parts is connected in a two-part drive housing injection-molded from synthetic material. drive pinion of a equipped with drag spring brake gear drive is engaged. A dividing plane of the two housing parts of the drive housing is located outside of the threaded cage guided by the housing and of the drive pinion between the latter and the drag spring brake. The dividing plane further affects the outer circumference of the threaded cable, so that the threaded cable leads to the drive pinion and to the graduation plane open guide channel in which a housing part is formed. As a result, the axial spacing between the drive pinion and the threaded cable is always maintained ex¬ actively by the defined position of the guide channel in the one housing part which is predetermined by the injection mold. The aforementioned position of the housing dividing plane ensures that the two housing parts are not forced apart by the contact pressure caused as a result of the tooth engagement on the cable. The threaded cable runs inside the guide tube, which is arranged in the interior of a vehicle door.
Die vorliegende Erfindung beschäftigt sich mit dem Problem, für eine Fensterhebeeinrichtung eingangs erwähnter Art eine verbesserte Ausführungsform anzugeben, welche insbesondere den Diebstahlschutz des Kraftfahrzeugs erhöht.The present invention is concerned with the problem of providing for a window lifting device of the kind mentioned an improved embodiment, which in particular increases the theft protection of the motor vehicle.
Dieses Problem wird durch den Gegenstand des unabhängigen An¬ spruchs gelöst. Vorteilhafte Ausführungsformen sind Gegens¬ tand der abhängigen Ansprüche.This problem is solved by the subject matter of the independent claim. Advantageous embodiments are the subject of the dependent claims.
Die Erfindung beruht auf allgemeinen Gedanken, bei einer Fensterhebeeinrichtung, insbesondere bei einer Fensterhebe¬ einrichtung für eine Kraftfahrzeugtür, mit einem Fensterhe¬ ber, der über zumindest ein Verstellglied mit einem Mitnehmer und einer damit verbundenen Fensterscheibe kraftübertragungs¬ gekoppelt ist, das Verstellglied von zumindest einer Schutz- blende wenigstens teilweise zu verdecken und es dadurch bei in die Fahrzeugtür eingebautem Zustand von außen nicht oder nur schwer zugänglich zu machen.The invention is based on general thoughts, in a window lifting device, in particular a Fensterhebe¬ device for a motor vehicle door, with a Fensterhe¬ over which is coupled kraftübertragungs¬ at least one adjusting member with a driver and an associated window, the adjustment of at least one Protection- Aperture to hide at least partially and thus make it difficult to access from the outside when installed in the vehicle door condition.
Da ein Durchtrennen des Verstellglieds, beispielsweise eines Zugseils, die Verbindung zwischen dem Mitnehmer und dem Fens¬ terheber unterbricht und dadurch ein händisches Öffnen des Fensters durch ein einfaches Herabschieben ermöglicht, sollte das Verstellglied von außen gegen einen unbefugten Zugriff geschützt werden. Das Verstellglied kann dabei ein geschlos¬ sener Seilzug sein, an welchem der Mitnehmer fest angeordnet ist. Denkbar ist auch, dass das Verstellglied ein Hubseil und ein Gegenhubseil aufweist, welche jeweils mit dem Mitnehmer und dem Fensterheber verbunden sind. Durch das Verdecken des Verstellglieds mittels der Schutzblende, kann das Verstell¬ glied wirkungsvoll vor einem direkten Zugriff von außen ge¬ schützt werden und dadurch das Eindringen in das Fahrzeug er¬ schwert bzw. verhindert werden. Ein erhöhter Diebstahlschutz gewährleistet dabei zum einen größere Sicherheit gegen ein Aufbrechen und ein Entwenden des Fahrzeugs und ermöglicht zum anderen eine günstigere Einstufung in der Versicherung.Since a severing of the adjusting, for example, a pull rope, the connection between the driver and the Fens¬ terheber interrupts and thereby enables a manual opening of the window by simply pushing down the adjustment should be protected from the outside against unauthorized access. The adjusting member can be a closed cable, to which the driver is fixed. It is also conceivable that the adjusting member has a hoisting rope and a counter-lifting cable, which are each connected to the driver and the window regulator. By concealing the adjusting member by means of the protective cover, the adjusting member can be effectively protected against direct access from the outside, thereby making it possible to prevent or prevent intrusion into the vehicle. An increased theft protection ensures on the one hand greater security against breaking up and stealing the vehicle and on the other hand allows a more favorable classification in the insurance.
Gemäß einer bevorzugten Ausführungsform der erfindungsgemäßen Lösung ist die Schutzblende aus Metall und/oder aus Kunst¬ stoff. Unabhängig von der Auswahl des Materials für die Schutzblende sollte stets gewährleistet sein, dass diese ei¬ nen effektiven Schutz vor einem unbefugten Zugriff auf das Verstellglied bietet. Eine Schutzblende aus Kunststoff bietet dabei den Vorteil, dass sie zum einen in einem geeigneten Spritzgusswerkzeug in nahezu beliebiger Form und damit pass¬ genau herstellbar ist und zum anderen aufgrund des geringen Gewichts nahezu keinen erhöhten Energieverbrauch des Fahr¬ zeugs zur Folge hat. Denkbar ist hierbei auch eine Kombinati¬ on von mehreren Werkstoffen, wie beispielsweise Metall und Kunststoff, wobei beispielsweise die Befestigungspunkte der Schutzblende aus Metall und der Rest aus Kunststoff ausgebil¬ det sein kann, so dass die günstigen Eigenschaften beider Werkstoffe optimal miteinander kombiniert werden können.According to a preferred embodiment of the solution according to the invention, the protective screen is made of metal and / or plastic. Irrespective of the selection of the material for the protective cover, it should always be ensured that this provides effective protection against unauthorized access to the adjusting element. A protective cover made of plastic offers the advantage that on the one hand in a suitable injection molding tool in almost any shape and thus pass¬ accurately produced and on the other hand due to the low weight almost no increased energy consumption of the vehicle Fahr¬ result. Conceivable here is also a combination of several materials, such as metal and Plastic, wherein, for example, the attachment points of the protective cover made of metal and the rest of plastic can be ausgebil¬ det, so that the favorable properties of both materials can be optimally combined.
Zweckmäßig ist die Schutzblende an der Fahrzeugtür angebracht oder ausgebildet. Denkbar ist hierbei, dass die Schutzblende bereits bei der Herstellung eines Türrahmens an diesen ange¬ formt bzw. an diesem vorgesehen wird und dadurch der erhöhte Diebstahlschutz bereits werkseitig ausgebildet werden kann. Um nachträglich eine bessere Einstufung bezüglich der Versi¬ cherungsprämie zu erreichen, können auch entsprechende Schutzblenden, beispielsweise über den Zubehörhandel, ver¬ trieben werden, welche nachträglich in. oder an der Fahrzeug¬ tür angebracht werden können und das Verstellglied wirkungs¬ voll abdecken.Suitably, the protective cover is attached or formed on the vehicle door. It is conceivable here that the protective cover is already formed or provided on the door during the production of a door frame, and thus the increased theft protection can already be formed at the factory. In order subsequently to achieve a better classification with regard to the insurance premium, it is also possible to use corresponding protective covers, for example via the aftermarket, which can be retrofitted in or on the vehicle door and effectively cover the adjusting element.
Entsprechend einer besonders bevorzugten Ausführungsform bil¬ det die Schutzblende einen umfangsmäßig zumindest halbge¬ schlossenen Kanal, in dem das Verstellglied verläuft. Hierbei kann beispielsweise der Schutzblende zusätzlich eine Füh¬ rungsfunktion für das Verstellglied zukommen, wodurch die Schutzblende einen Zusatznutzen erhält. Darüber hinaus bietet der zumindest halb geschlossene Kanal den Vorteil, das Ver¬ stellglied besonders effektiv vor unbefugten Zugriff zu schützen.According to a particularly preferred embodiment, the protective screen forms a channel which is circumferentially at least semi-closed and in which the adjusting member runs. In this case, for example, the protective cover can also be provided with a guiding function for the adjusting element, as a result of which the protective cover receives an additional benefit. In addition, the at least half-closed channel has the advantage of protecting the adjusting member against unauthorized access in a particularly effective manner.
Weitere wichtige Merkmale und Vorteile der Erfindung ergeben sich aus den ünteransprüchen, aus der Zeichnung und aus der zugehörigen Figurenbeschreibung anhand der Zeichnung.Further important features and advantages of the invention will become apparent from the dependent claims, from the drawing and from the associated description of the figures with reference to the drawing.
Es versteht sich, dass die vorstehend genannten und die nach¬ stehend noch zu erläuternden Merkmale nicht nur in der je¬ weils angegebenen Kombination, sondern auch in anderen Kombi- nationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen.It is understood that the features mentioned above and those yet to be explained not only in the combination indicated, but also in other combinations. nations or alone, without departing from the scope of the present invention.
Ein bevorzugtes Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird in der nachfolgenden Beschrei¬ bung näher erläutert.A preferred embodiment of the invention is shown in the drawing and will be explained in more detail in the following descrip tion.
Die einzige Fig. 1 zeigt eine erfindungsgemäße Fensterhebe¬ einrichtung mit einer Schutzblende.The only Fig. 1 shows a Fensterhebe¬ device according to the invention with a protective cover.
Entsprechend Fig. 1 weist eine erfindungsgemäße Fensterhebe¬ einrichtung 1 einen Mitnehmer 2 auf, welcher an einer Füh¬ rungsschiene 3 verstellbar gelagert ist. Am Mitnehmer 2 ist eine Fensterscheibe 4 angeordnet, welche aufgrund der Ver¬ stellbewegungen des Mitnehmers 2 entlang der Führungsschiene 3 verstellt wird. Zum Verstellen des Mitnehmers 2 ist dieser über ein Verstellglied 5 mit einem nicht dargestellten Fens¬ terheber kraftübertragungsgekoppelt. Die Fensterhebeeinrich¬ tung 1 ist gemäß Fig. 1 für den Antrieb einer Seitenscheibe 4 in einer nicht dargestellten Kraftfahrzeugtür vorgesehen.According to FIG. 1, a window lifting device 1 according to the invention has a driver 2, which is mounted adjustably on a guide rail 3. At the driver 2, a window pane 4 is arranged, which is adjusted due to the Ver¬ adjusting movements of the driver 2 along the guide rail 3. For adjusting the driver 2, it is force-transmittingly coupled via an adjusting member 5 to a window lifter (not shown). The Fensterhebeeinrich¬ device 1 is provided in FIG. 1 for driving a side window 4 in a motor vehicle door, not shown.
Das Verstellglied 5 kann dabei ein geschlossener, umlaufender Seilzug sein, an welchem der Mitnehmer 2 fest angeordnet ist oder beispielsweise ein Bowdenzug, welcher sowohl eine Hub¬ ais auch eine Senkbewegung der Fensterscheibe 4 bewirkt. Denkbar ist auch, dass das Verstellglied 5 ein Hubseil und ein Gegenhubseil aufweist, welche jeweils mit dem Mitnehmer 2 und dem Fensterheber verbunden sind.The adjusting member 5 may be a closed, circulating cable, on which the driver 2 is fixed or, for example, a Bowden cable, which causes both a Hub¬ ais and a lowering movement of the window 4. It is also conceivable that the adjusting member 5 has a hoist rope and a Gegenhubseil, which are each connected to the driver 2 and the window regulator.
Bei geschlossener Seitenscheibe 4 bleibt der Mitnehmer 2 von außen unsichtbar unterhalb einer Fensterschachtabdichtung 6, so dass die Fensterhebeeinrichtung 1 weder bei geöffneter noch bei geschlossener Seitenscheibe 4 von außen sichtbar ist. Da ein Durchtrennen des Verstellglieds 5, beispielsweise des Hubseils, zur Folge hätte, dass die Fensterscheibe 4 problem¬ los von Hand geöffnet werden kann, gilt es dieses gegen einen unbefugten Zugriff von außen wirksam zu schützen. Hierzu sieht die Erfindung vor, dass das Verstellglied 5 von zumin¬ dest einer Schutzblende 7 wenigstens teilweise verdeckt ist, so dass das Verstellglied 5 bei in die Fahrzeugtür eingebau¬ tem Zustand von außen nicht oder nur schwer zugänglich ist. Der erschwerte bzw. nicht mögliche Zugriff von außen auf das Verstellglied 5 erhöht somit den Diebstahlschutz und bietet darüber hinaus die Möglichkeit aufgrund des erhöhten Dieb¬ stahlschutzes das Fahrzeug in eine günstigere Versicherungs¬ klasse einstufen zu lassen, wodurch Kostenvorteile realisiert werden können.When the side window 4 is closed, the carrier 2 remains invisible from the outside underneath a window shaft seal 6, so that the window lifting device 1 is not visible from the outside either when the side window 4 is open or closed. Since a severing of the adjusting member 5, for example of the hoisting cable, would result in the window pane 4 being able to be opened by hand without difficulty, it must be effectively protected against unauthorized access from the outside. For this purpose, the invention provides that the adjusting member 5 is at least partially concealed by at least one protective screen 7, so that the adjusting member 5 is not accessible or difficult to access from the outside when the vehicle is in a built-in state. The difficult or impossible access from the outside to the adjusting member 5 thus increases the theft protection and moreover offers the possibility of classifying the vehicle in a more favorable insurance class due to the increased theft protection, whereby cost advantages can be realized.
Die Schutzblende 7 kann dabei beispielsweise als Stanzteil aus Metall und/oder als Spritzgussteil aus Kunststoff ausge¬ bildet sein. Ein Spritzgussteil aus Kunststoff bietet die Möglichkeit nahezu jede beliebige Form auszubilden, wobei gleichzeitig aufgrund des geringen Gewichts des Kunststoffes kein wesentlich erhöhter Energiebedarf des Kraftfahrzeugs mit der Schutzmaßnahme einhergeht.The protective cover 7 can be formed, for example, as a stamped part made of metal and / or as an injection molded part made of plastic. An injection-molded part made of plastic offers the possibility of forming almost any shape, while at the same time, due to the low weight of the plastic, there is no significantly increased energy requirement of the motor vehicle associated with the protective measure.
Generell ist denkbar, dass die Schutzblende 7 an der Fahr¬ zeugtür angebracht oder ausgebildet ist. Bei neu konzipierten Fahrzeugen bzw. Fahrzeugtüren kann deshalb die Schutzblende 7 bereits Bestandteil eines Türrahmens sein, so dass das Ver¬ stellglied 5 nach dessen Einbau problemlos überdeckt wird, ohne dass zusätzliche Maßnahmen, wie beispielsweise ein An¬ schrauben der Schutzblende 7, ergriffen werden müssen. Um Kraftfahrzeuge nachträglich besser gegen Aufbruch bzw. Dieb¬ stahl zu schützen, kann die Schutzblende 7 auch über den Zu- behörhandel vertrieben werden und nachträglich an geeigneter Stelle in der Fahrzugtür angeordnet werden.In general, it is conceivable that the protective cover 7 is attached or formed on the vehicle door. For newly designed vehicles or vehicle doors, therefore, the protective cover 7 may already be part of a door frame, so that the adjusting member 5 is easily covered after its installation, without additional measures, such as An¬ screws the protective cover 7, must be taken , In order subsequently to protect motor vehicles better against breakage or theft, the protective screen 7 can also be used to protect against theft or theft. be sold and subsequently arranged at a suitable location in the vehicle door.
Dabei ist denkbar, dass die Schutzblende 7 einen umfangsmäßig zumindest halbgeschlossenen Kanal bildet, in dem das Ver¬ stellglied 5 verläuft. Hierbei könnte der Schutzblende 7 zu¬ sätzliche eine Führungsfunktion für das Verstellglied 5 zuge¬ wiesen werden, wodurch ein Zusatznutzen erreicht wird.It is conceivable that the protective cover 7 forms a circumferentially at least half-closed channel in which the adjusting member 5 extends. In this case, the protective screen 7 could additionally be assigned a guide function for the adjusting member 5, whereby an additional benefit is achieved.
Gemäß Fig. 1 ist die Schutzblende 7 derart ausgebildet, dass sie das Verstellglied 5 insbesondere in einem kritischen Be¬ reich, d.h. in einem Bereich kurz unterhalb der Fenster¬ schachtabdichtung 6, vor einem unbefugten Zugriff schützt. Im weiteren Verlauf verläuft das Verstellglied 5 wiederum frei innerhalb der Fahrzeugtür zum Fensterheber, wobei es in sei¬ nem frei verlaufenden Bereich bezüglich eines unbefugten Zugriffs von außen weniger oder nicht gefährdet ist.According to FIG. 1, the protective screen 7 is designed such that it supports the adjusting member 5, in particular in a critical region, i. in an area just below the window shaft seal 6, protects against unauthorized access. In the further course, the adjusting member 5 again runs freely within the vehicle door to the window lifter, wherein it is less or not at risk in its free running area with respect to an unauthorized access from the outside.
Generell ist denkbar, dass die Schutzblende 7 einteilig oder mehrteilig ausgebildet ist, wobei insbesondere bei einer mehrteiligen Ausbildung die Schutzblendenteilstücke nur an denjenigen Stellen angeordnet werden, welche besonders durch einen unbefugten Zugriff von außen gefährdet sind.In general, it is conceivable that the protective cover 7 is formed in one or more parts, wherein in particular in a multi-part design, the protective screen sections are arranged only at those points which are particularly vulnerable to unauthorized access from the outside.
Zusammenfassend lassen sich die wesentliche Merkmale der er¬ findungsgemäßen Lösung wie folgt charakterisieren:In summary, the essential features of the solution according to the invention can be characterized as follows:
Die Erfindung sieht vor, bei einer Fensterhebeeinrichtung 1, mit einem Fensterheber, welcher über zumindest ein Verstell¬ glied 5 mit einem Mitnehmer 2 und einer damit verbundenen Fensterscheibe 4 kraftübertragungsgekoppelt ist, das Ver¬ stellglied 5 zumindest von einer Schutzblende 7 wenigstens teilweise zu verdecken. Hierdurch ist das Verstellglied 5 bei in die Fahrzeugtür eingebautem Zustand von außen nicht oder nur schwer zugänglich, wodurch der Schutz gegen Aufbruch bzw. Diebstahl des Kraftfahrzeugs verbessert werden kann und zugleich eine günstigere Einstufung bezüglich einer Versiche¬ rungsklasse erreicht werden kann. The invention provides, in a window lifting device 1, with a window, which is power transmission coupled via at least one Verstell¬ member 5 with a driver 2 and an associated window pane 4, at least partially conceal the Ver¬ actuator 5 of a protective panel 7 at least. As a result, the adjusting member 5 is not installed when installed in the vehicle door state from the outside difficult to access, whereby the protection against break-up or theft of the motor vehicle can be improved and at the same time a more favorable classification can be achieved with respect to a insurance class.
