Abstract

A window pane (3) for a vehicle door (1) can be raised and lowered by a lifter (4) located in a door recess (2). A low friction, ice repelling coating (10), typically PTFE is applied to the outer face (3') of the window (3) such that in the closed position of the window (3) the coating (10) extends from the window sill (7) down to near the lower edge of the window pane (3). A seal (6) located along the window sill area (7) wipes the coating (10) during window operation. USE/ADVANTAGE - Enables ice to be removed easily from opening vehicle windows in the sill areas ensuring low stresses are placed on the window lifting gear.

Description

Die Erfindung bezieht sich auf eine in einem Fenster­ schacht eines Kraftfahrzeugs verschiebbare, insbesondere höhenverschiebbare Fensterscheibe der im Oberbegriff des Patentanspruchs 1 genannten und beispielsweise aus der DE-OS 36 17 602 hervorgehenden Art.The invention relates to a in a window shaft of a motor vehicle displaceable, in particular height-adjustable window pane in the preamble of Claim 1 mentioned and for example from the DE-OS 36 17 602 emerging Art.

Damit eine in einem Fensterschacht angeordnete Fenster­ scheibe mit möglichst geringem Kraftaufwand höhenver­ schiebbar ist, ist üblicherweise das an der Fenster­ außenseite anliegende Dichtelement mit einer Beflockung versehen. Diese saugt jedoch die ggf. an der Fenster­ außenseite vorhandene Feuchtigkeit auf, wodurch bei sehr tiefen Temperaturen das Dichtelement an der Fenster­ scheibe anfrieren kann. Hierdurch wird der Fensterheber beim Öffnungsvorgang der Fensterscheibe sehr hoch beansprucht, so daß ein Teil des Fensterhebers brechen kann und dieser damit nicht mehr funktionsfähig ist. Ein mit Gleitlack oder dergleichen beschichtetes Dichtele­ ment kann an der Fensteraußenseite aufgrund der an dieser häufig vorhandenen Schmutzpartikel beim Verlagern der Fensterscheibe Kratzspuren oder dgl. erzeugen.So that a window arranged in a window shaft disc with the least possible effort is usually on the window external sealing element with flocking Mistake. However, this sucks the possibly on the window moisture present on the outside, which means very low temperatures the sealing element on the window freeze pane. This will make the window lifter very high when opening the window claimed so that part of the window regulator break can and this is no longer functional. A Sealant coated with lubricating varnish or the like ment can be on the outside of the window due to the of these frequently present dirt particles when moving generate scratches or the like on the window pane.

Aufgabe der Erfindung ist es daher, bei einer Fenster­ scheibe der im Oberbegriff des Patentanspruchs 1 ge­ nannten Art eine Einrichtung vorzusehen, durch die sich eine in Schließstellung befindende Fensterscheibe auch bei sehr tiefen Temperaturen problemlos öffnen läßt.The object of the invention is therefore in a window slice of ge in the preamble of claim 1 referred to provide a facility through which  a window pane in the closed position also can be opened easily at very low temperatures.

Zur Lösung der Aufgabe sind die im kennzeichnenden Teil des Patentanspruchs 1 dargelegten Merkmale vorgesehen.To solve the problem are those in the characterizing part of the features set forth in claim 1.

Durch die erfindungsgemäß an der Außenseite der Fen­ sterscheibe abriebfest angeordnete, eisabweisende Beschichtung, die in Schließstellung der Fensterscheibe mit dem Dichtelement zusammenwirkt und die zweckmäßi­ gerweise aus Polytetraflouretylen oder dergleichen besteht, wird ein Anfrieren des mit einer Beflockung versehenen Dichtelements an der Fensterscheibe auch bei sehr tiefen Temperaturen verhindert. Somit wird bei einer vereisten Fensterscheibe nicht nur der Kraft­ aufwand zu deren Abwärtsbewegen aus der Schließstellung erheblich vermindert, sondern es wird auch ein manuell betätigter Fensterheber nicht beschädigt und der Motor eines elektrischen Fensterhebers weniger belastet. Schließlich wird auch die Beflockung des Dichtelements sehr geschont, da diese beim Öffnungsvorgang der Fen­ sterscheibe nicht losgerissen wird.Due to the invention on the outside of the fen anti-abrasion, ice-resistant Coating in the closed position of the window pane interacts with the sealing element and the expedient sometimes from polytetrafluoroethylene or the like there is a freezing of the flocked provided sealing element on the window pane also prevents very low temperatures. Thus at an icy window not only of strength effort to move them down from the closed position significantly reduced, but it also becomes a manual operated window lifter and the motor are not damaged of an electric window regulator is less stressed. Finally, the flocking of the sealing element very spared, as this happens when opening the fen window is not torn off.

Gemäß dem Merkmal des Patentanspruchs 3 erstreckt sich die eisabweisende Beschichtung in Schließstellung der Fensterscheibe vom Bereich der Fensterbrüstungsoberkante bis nahe zum unteren Rand der Fensterscheibe. Dabei ist jedoch im Bereich der Fensterheberaufnahme keine eisab­ weisende Beschichtung vorgesehen.According to the feature of claim 3 extends the ice-repellent coating in the closed position of the Window pane from the area of the top of the window sill to near the bottom of the window. It is however, there is no ice in the area of the window regulator mount facing coating provided.

Ein Ausführungsbeispiel der Erfindung ist in der Zeich­ nung dargestellt und wird im folgenden erläutert; diese zeigt einen Vertikalschnitt einer Fensterscheibe im Seitenbereich eines Personenkraftwagens in Schließ­ stellung. An embodiment of the invention is in the drawing voltage and is explained below; these shows a vertical section of a window in Side area of a passenger car in closing position.  

Eine Tür 1 eines Personenkraftwagens hat zwischen seinen beiden Wandungen einen etwa senkrecht verlaufenden Fensterschacht 2, in dem eine Fensterscheibe 3 ange­ ordnet ist. Diese ist durch einen an ihrem unteren Rand angebrachten Fensterheber 4 in den Richtungen des Doppelpfeils a höhenverschiebbar, wobei sich die Fen­ sterscheibe 3 in der Zeichnung in Schließstellung b befindet; dabei greift sie in eine Nut des Dachrahmens 8 ein.A door 1 of a passenger car has an approximately perpendicular window shaft 2 between its two walls, in which a window pane 3 is arranged. This is vertically displaceable by a window lifter 4 attached to its lower edge in the directions of the double arrow a, the window 3 in the drawing being in the closed position b; it engages in a groove of the roof frame 8 .

Zur Abdichtung der Fensterscheibe 3 dient jeweils ein am innenliegenden und am außenliegenden Rand des Fenster­ schachts 2 vorgesehenes und längs diesem verlaufendes Dichtelement 5 und 6, die jeweils abdichtend an der Fensterscheibe 3 anliegen. Dabei ist das außenliegende Dichtelement 6 mit einer an der Außenseite 3′ der Fensterscheibe 3 anliegenden Beflockung versehen. Damit das Dichtelement 6 bei sich in Schließstellung b befin­ dender Fensterscheibe 3 nicht an deren eine Feuchtigkeit aufweisenden Außenseite 3′ anfrieren kann, ist diese mit einer aus Polytetrafluoretylen oder dergleichen beste­ henden, eisabweisenden Beschichtung 10 versehen. Diese verläuft bei sich in Schließstellung b befindender Fensterscheibe 3 von etwas oberhalb der Fensterbrüstung 7 bis nahe zum unteren Rand der Fensterscheibe 3, wobei jedoch die eisabweisende Beschichtung 10 außerhalb der Aufnahme des Fensterhebers 4 liegt.To seal the window pane 3 is used on the inside and on the outside edge of the window shaft 2 provided and extending along this sealing element 5 and 6 , each sealingly abut the window pane 3 . The outer sealing element 6 is provided with a flocking on the outside 3 'of the window pane 3 . So that the sealing element 6 when the window 3 is in the closed position b cannot freeze to the outside of which has a moisture on the outside 3 ', this is provided with a best existing, ice-repellent coating 10 made of polytetrafluoroethylene or the like. When the window pane 3 is in the closed position b, this extends from somewhat above the window parapet 7 to close to the lower edge of the window pane 3 , but the ice-repellent coating 10 lies outside the receptacle of the window lifter 4 .

Da somit das außenliegende Dichtelement 6 in Schließ­ stellung b der Fensterscheibe 3 an der eisabweisenden Beschichtung 10 anliegt, läßt sich auch bei sehr tiefen Temperaturen die Fensterscheibe 3 problemlos abwärts verlagern, ohne daß dabei die am außenliegenden Dicht­ element 6 vorhandene Beflockung oder ein Teil des Fensterhebers 4 beschädigt wird. Dabei kann die eisab­ weisende Beschichtung 10 auf die Außenseite 3′ der Fensterscheibe 3 abriebfest aufgespritzt oder durch Tauchen aufgetragen werden. Darüber hinaus kann auch die eisabweisende Beschichtung 10 aus einer selbstklebenden Folie bestehen, die auf die Außenseite 3′ der Fenster­ scheibe 3 abriebfest aufgeklebt wird.Thus, since the outer sealing element 6 in the closed position b of the window pane 3 bears against the ice-repellent coating 10 , the window pane 3 can be moved downwards without problems even at very low temperatures without the flocking on the outer sealing element 6 or part of the window regulator 4 is damaged. The eisab-facing coating 10 can be sprayed on the outside 3 'of the window pane 3 wear-resistant or applied by dipping. In addition, the ice-repellent coating 10 can consist of a self-adhesive film, which is glued to the outside 3 'of the window pane 3 in an abrasion-resistant manner.
