Eine Drehverbindung benötigt kein Gewinde wie eine Schraubverbindung, insbesondere kann eine Drehverbindung durch eine Drehung kleiner als 360 Grad geschlossen werden. Dadurch werden die Anzahl der Arbeits schritte vor und während der Montage verringert und dadurch Kosten reduziert. Durch die in den Unteransprüchen aufgeführte Maßnahmen ergeben sich vorteilhafte Weiterbildungen und Verbesserung der im Hauptanspruch angegebenen Merkmale.Motor vehicle can be attached. A slewing ring does not require a thread like a screw connection, in particular a slewing ring can be closed by turning less than 360 degrees. This reduces the number of work steps before and during assembly, thereby reducing costs. The measures listed in the subclaims result in advantageous further developments and improvements in the features specified in the main claim.

Besonders vorteilhaft ist, wenn die Drehverbindung eine Raste aufweist, die zur Orientierung des Verschlusselementes- dient und dieses in einer bevorzugten Stellung arretiert. Auf diese Weise wird die Verbindungsfestigkeit erhöht, sodass sich die Verbindung auch bei starken, länger andauernden Erschütterungen, wie sie sich im Fahrbetrieb ständig ergeben, nicht von selbst löst.It is particularly advantageous if the rotary connection has a catch which serves to orient the closure element and lock it in a preferred position. In this way, the connection strength is increased so that the connection does not come off by itself even in the event of strong, longer-lasting vibrations, such as those which constantly arise during driving.

Besonders einfach wird die Drehverbindung dadurch realisiert, dass der Träger eineThe rotary connection is realized particularly simply in that the carrier has a

Figur 1 zeigt eine erfindungsgemäße Scheibenwischvorrichtung 10 in schematischer Darstellung. Diese u fasst im wesentlichen einen Träger 12 der aus einem Rohr besteht, an dessen Enden jeweils ein Wischerlager 14, 16 angeordnet ist. Jedes Wischerlager 14, 16 weist Ohren 18, 20 auf, welche jeweils eine Öffnung 22, 24 besitzen. In den Wischerlagern 14, 16 sind darüber hinaus Wischerwellen 26, 28 gelagert, die mit hier nicht gezeigten Wischerarmen verbunden sind. Angetrieben werden die Wischerwellen 26, 28 über ein Kurbelgetriebe 30, 32, welches von einer Motor 34 in Bewegung versetzt wird.Figure 1 shows a windshield wiper device 10 according to the invention in a schematic representation. This u essentially comprises a support 12 which consists of a tube, at the ends of which a wiper bearing 14, 16 is arranged. Each wiper bearing 14, 16 has ears 18, 20, each of which has an opening 22, 24. In the wiper bearings 14, 16, wiper shafts 26, 28 are also mounted, which are connected to wiper arms, not shown here. The wiper shafts 26, 28 are driven by a crank mechanism 30, 32, which is set in motion by a motor 34.

Figur 2 zeigt ein Wischerlager einer erfindungsgemäßen Scheibenwischvorrichtung in einer Explosionsdarstellung. Das Wischerlager 14 als Teil des Trägers 12 weist ein Ohr 18 mit einer Öffnung 22 auf. In die Öffnung 22 wird die Dämpfungsmuffe 36, 38 eingesteckt, die hier zweiteilig ausgeführt ist. Natürlich ist auch denkbar, die Muffe 36, 38 einteilig auszuführen. Die Dämpfungsmuffen 36, 38 sind als Gummischeiben ausgebildet, die auch formschlüssig in der Öffnung 22 des Trägers 12 sitzen können. In die Öffnung 22 mit den Dämpfungsmuffen 36, 38 ist ein Verschlusselement 40 eingefügt, welche im wesentlichen drei Abschnitte aufweist. Ein erster ellipsenförmiger Abschnitt 42 an den sich ein zweiter kreiszylindrischer Abschnitt 44 anschließt. An diesen schließt sich wiederum ein dritter kreisscheibenförmiger Abschnitt 46 an. Der erste scheibenförmige, im Querschnitt ellipsenförmige Abschnitt 42 weist eine Höhe von Hl auf und besitzt eine Quernut 48 der Breite B.Figure 2 shows a wiper bearing of a windshield wiper device according to the invention in an exploded view. The wiper bearing 14 as part of the carrier 12 has an ear 18 with an opening 22. In the opening 22, the damping sleeve 36, 38th inserted, which is carried out here in two parts. Of course, it is also conceivable to design the sleeve 36, 38 in one piece. The damping sleeves 36, 38 are designed as rubber washers, which can also sit in a form-fitting manner in the opening 22 of the carrier 12. A closure element 40, which has essentially three sections, is inserted into the opening 22 with the damping sleeves 36, 38. A first elliptical section 42 to which a second circular cylindrical section 44 connects. This is in turn followed by a third circular-shaped section 46. The first disc-shaped section 42, which is elliptical in cross-section, has a height of H 1 and has a transverse groove 48 of width B.

Im dritten Abschnitt 46 ist darüber hinaus ein Eingriff 50 angeordnet, der beispielsweise als Vielkant oder als Schlitz ausgebildet ist, in dem ein.Werkzeug eingefügt werden kann, um das Verschlusselement 40 bei der Montage leicht drehen zu können.In the third section 46 there is also an engagement 50, which is designed, for example, as a polygon or as a slot in which a tool can be inserted in order to be able to easily turn the closure element 40 during assembly.

Das Verschlusselement 40 selbst wird bei der Montage in ein erstes Teil 52 eingesteckt und relativ zu diesem um einen Winkel kleiner 360 Grad verdreht. Das erste Teil 52 ist dabei als Blechteil, insbesondere als Stanzbiegeteil ausgebildet, weist die Dicke D auf und ist mit der Fahrzeugkarosserie verbunden. Darüber hinaus weist es ein Loch 54 auf, welches dieselbe Kontur hat, wie der erste Abschnitt 42 des Verschlusselements 40, so daß dieses das erste Teil 54 durchdringen kann. Idealerweise ist das erste Teil 52 einstückig mit der Fahrzeugkarosserie ausgebildet.The closure element 40 itself is inserted into a first part 52 during assembly and rotated relative to the latter by an angle of less than 360 degrees. The first part 52 is designed as a sheet metal part, in particular as a stamped and bent part, has the thickness D and is connected to the vehicle body. In addition, it has a hole 54 which has the same contour as the first section 42 of the closure element 40 so that it can penetrate the first part 54. Ideally, the first part 52 is formed in one piece with the vehicle body.

Die Quernut 48, deren Breite B typischerweise größer ist als die Dicke D des Teils 52, lässt zwei Laschen 49, 49a entstehen, die über das Querschnittsprofil des zweiten Abschnitts hinausragen. Natürlich kann, anstatt der Queraut 48 auch eine einfache Stufe vorgesehen sein, sodass die Laschen 49, 49a ebenfalls über die Kontur des zweiten Abschnitts hinausragen.The transverse groove 48, the width B of which is typically greater than the thickness D of the part 52, creates two tabs 49, 49a which protrude beyond the cross-sectional profile of the second section. Of course, instead of the transverse face 48, a simple step can also be provided, so that the tabs 49, 49a also protrude beyond the contour of the second section.

Bei der Montage durchdringt der erste Abschnitt 42 mit den Laschen 49, 49a des Verschlusselementes 40 das erste Teil 52, durch das Loch 54. Durch Verdrehen desDuring assembly, the first section 42 with the tabs 49, 49a of the closure element 40 penetrates the first part 52, through the hole 54

Verschlusselementes 40 wird der Träger 12 der Scheibenwischvorrichtung 10 mit dem ersten Teil 52 als Teil der Fahrzeugkarosserie verbunden. Im Bereich des Lochs 54 weist das Teil 52 Erhebungen oder Ausstanzungen derart auf, dass eine radiale, gewindeartige Schräge 56 entsteht, an der die Laschen 49, 49a beim Drehen des Verschlusselementes 40 entlang gleiten, sodass sich der Abstand des dritten Abschnitts 46 des Verschlusselementes 40 und 'dem ersten Teil 52 verringert und das Verschlusselement 40 • quasi in das Teil 52 hineingezogen wird. Am hohen Ende der Schräge 56, ist noch eine Raste 58 vorgesehen, die als kleine Senke ausgebildet ist, in die zumindest eine Lasche 49 hineingleitet. Diese verhindert ein Abgleiten der Lasche 49 an der Schräge 56, wenn sich das Verschlußelement 40 im verschlossener Position befindet. So ergibt sich einClosure element 40, the carrier 12 of the windshield wiper device 10 is connected to the first part 52 as part of the vehicle body. In the area of the hole 54, the part 52 has elevations or punched-out areas such that a radial, thread-like bevel 56 is formed, along which the tabs 49, 49a slide along when the closure element 40 is rotated, so that the distance between the third section 46 of the Closure element 40 and 'the first part 52 is reduced and the closure member 40 is drawn quasi • in the part 52nd At the high end of the bevel 56, a notch 58 is also provided, which is designed as a small depression into which at least one tab 49 slides. This prevents the tab 49 from sliding off the slope 56 when the closure element 40 is in the closed position. So there is a

Das Verschlusselement 40 hat die Dämpfungselemente 36, 38, sowie die Öffnung 22 und das erste Teil 52 durch das Loch 54 durchdrungen und wurde um etwa 90° zu seiner Längsachse verdreht. Auf dieser Weise bilden die Laschen 49, 49a Halterungen am Teil 52 derart, daß der Träger der Scheibenwischvorrichtung 10 zwischen den dritten Abschnitt 46 des Verschlusselementes 40 und den Laschen 49, 49a des ersten Abschnitts des Verschlusselementes eingeklemmt ist.Figure 4 shows the mounting area of the bracket 12 in an assembled view. The closure element 40 has penetrated the damping elements 36, 38, as well as the opening 22 and the first part 52 through the hole 54 and was rotated by approximately 90 ° to its longitudinal axis. In this way, the tabs 49, 49a form holders on the part 52 such that the carrier of the windshield wiper device 10 is clamped between the third section 46 of the closure element 40 and the tabs 49, 49a of the first section of the closure element.

In Figur 5 ist eine Variation der erfindungsgemäßen Scheibenwischvorrichtung gezeigt. Das Verschlusselement 40 besteht wiederum aus drei Abschnitten. Der erste Abschnitt 42 entspricht einer doppelten Schlüssellochkontur und bildet dadurch zwei Laschen 49, 49a, die über die zylindrische Kontur des zweiten Abschnitts 44 hinausragen. Der zweiteFIG. 5 shows a variation of the windshield wiper device according to the invention. The closure element 40 again consists of three sections. The first section 42 corresponds to a double keyhole contour and thereby forms two tabs 49, 49a which protrude beyond the cylindrical contour of the second section 44. The second

Abschnitt 44 schließt sich an den ersten Abschnitt 42 direkt an und bildet mit diesem an den Laschen 49, 49a eine Stufe. An diesen zweiten Abschnitt 44 schließt sich wiederum der dritte Abschnitt 42 an, der den Eingriff 50 zur Aufnahme eines Werkzeugs aufweist.Section 44 directly adjoins the first section 42 and forms a step with the tabs 49, 49a. This second section 44 is in turn connected to the third section 42, which has the engagement 50 for receiving a tool.

Natürlich kann auch der dritte Abschnitt 46 beispielsweise in seiner Außenkontur alsOf course, the third section 46 can also be, for example, in its outer contour

Vielkant ausgebildet sein und somit selbst als Eingriff dienen. Die Dämpfungsmuffen 36, 38 sind hier einstückig ausgebildet und können als ganzes in die Öffnung 22 des Wischerlagers 14 des Trägers 12 eingefügt werden. Das Loch 54 des ersten Teils 52 hat wiederum die Kontur des doppelten Schlüsselloches, sodass das Loch den ersten Abschnitt 42 des Verschlusselementes 40 aufzunehmen vermag. Das Verschlusselement 40 ist als Kunststoffspritzgussteil ausgebildet, jedoch kann dieses auch aus einem Metall beispielsweise Aluminium, einer Aluminiumlegierung oder einer Zinklegierung ausgebildet sein. Die Dämpfungsmuffen 36 sind aus Gummi oder aus einem anderen elastischen Material, welches über ein gutes Dämpfungsverhalten verfügt. Das Teil 52 ist als einfacher Fortsatz an der Fahrzeugkarosserie festgeschweißt oder einstückig mit dieser ausgebildet. Die Wischerlager 14, 16 des Trägers 12 können aus Kunststoff aber auch aus Metall ausgebildet sein. Prinzipiell kann auch der gesamte Träger 12 einstückig aus Kunststoff gespritzt sein. Be polygonal and thus serve as an intervention. The damping sleeves 36, 38 are formed in one piece here and can be inserted as a whole into the opening 22 of the wiper bearing 14 of the carrier 12. The hole 54 of the first part 52 in turn has the contour of the double keyhole, so that the hole can accommodate the first section 42 of the closure element 40. The closure element 40 is designed as a plastic injection molded part, but this can also be formed from a metal, for example aluminum, an aluminum alloy or a zinc alloy. The damping sleeves 36 are made of rubber or another elastic material which has good damping behavior. The part 52 is welded to the vehicle body as a simple extension or is formed in one piece with it. The wiper bearings 14, 16 of the carrier 12 can be made of plastic but also of metal. In principle, the entire carrier 12 can also be injection-molded in one piece from plastic.
