Abstract

The blade has an upper bar (24) subdivided into parts that are separated by cuts in its longitudinal direction. A support element (26) has assembling windows that are moved in the direction, through which the parts of the bar are slid during assembling, where the element is made of plastic material. Projection parts form a space between the windows. The element is locked by sliding in the direction. A deflector (44) is installed as a distinct part on branches of the element, and has a plate sectioned longitudinal channel (46) that is positioned parallel to the element.

Description

Stand der TechnikState of the art

Die Erfindung geht von einem Wischblatt nach dem Oberbegriff des Anspruchs 1 aus.The Invention is based on a wiper blade according to the preamble of the claim 1 off.

Aus der DE 296 11 721 U1 ist ein Wischblatt in Flachbauweise mit den Merkmalen des Oberbegriffs bekannt. Das Tragelement ist so vorgekrümmt, dass die Anpresskraft eines Wischarms, die über ein gelenkiges Anschlusselement auf das Wischblatt übertragen wird, sich in Längsrichtung in geeigneter Weise verteilt, wobei die Wischlippe der Krümmung einer Fahrzeugscheibe folgen kann.From the DE 296 11 721 U1 is a flat wiper blade with the features of the preamble known. The support element is pre-curved so that the contact force of a wiper arm, which is transmitted via an articulated connection element on the wiper blade, distributed in the longitudinal direction in a suitable manner, wherein the wiper lip of the curvature of a vehicle window can follow.

Offenbarung der ErfindungDisclosure of the invention

Nach der Erfindung ist die Rückenleiste durch Aussparungen in Längsrichtung unterteilt. Dabei besitzt das Tragelement in Längsrichtung versetzt zu den Aussparungen Montagefenster, durch die die verbleibenden Teilstücke der Rückenleiste bei der Montage geschoben werden können, während Vorsprünge zwischen den Montagefenstern einen Spalt bilden und zwischen verbleibenden Teilstücken der Rückenleiste auf den Steg der Kopfleiste geschoben werden können. Durch eine Verschiebung des Tragelements in Längsrichtung gelangen die Vorsprünge des Tragelements unter die verbleibenden Teilstücke der Rückenleiste, sodass das Tragelement in Richtungen quer zur Längsachse verriegelt ist. Es ergibt sich bei einer geringen Teilevielfalt eine besonders günstige Montage. Das Tragelement des erfindungsgemäßen Wischblatts eignet sich für Wischblätter ohne und mit Spoiler. Der Spoiler weist zweckmäßigerweise einen Längskanal auf. Dieser dient zur Werkstoff- und Gewichtseinsparung und verbessert die Flexibilität des Spoilers. Außerdem kann er zur Aufnahme eines zusätzlichen Tragelements in Form einer Federschiene dienen. Die Tragelemente können entweder aus Federstahl in einem kostengünstigen Biege- und Stanzprozess gefertigt werden oder als Kunststoffteil in einem Spritzgießverfahren.To The invention is the back bar through Recesses in the longitudinal direction divided. In this case, the support element has offset in the longitudinal direction of the Recesses mounting window, through which the remaining sections of the back strip can be pushed during assembly, while protrusions between the mounting windows form a gap and between remaining sections the back bar can be pushed onto the bridge of the header. By a shift of the support element in the longitudinal direction get the projections of the Support member under the remaining portions of the back strip, so that the support element in directions transverse to the longitudinal axis is locked. It results with a small variety of parts a very cheap one Assembly. The support element of the wiper blade according to the invention is suitable for wiper blades without and with spoilers. The spoiler expediently has a longitudinal channel on. This serves to save material and weight and improves the flexibility the spoiler. Furthermore Can he accept an additional Serving support element in the form of a spring rail. The supporting elements can either spring steel in a cost-effective bending and stamping process be manufactured or as a plastic part in an injection molding.

Ausführungsformen der ErfindungEmbodiments of the invention

Ein Wischblatt 10 besitzt Wischleiste 12 mit einer Wischlippe 14, die über einen Kippsteg 16 mit einer Kopfleiste 18 ver bunden ist. Die Kopfleiste 18 weist zwei seitliche Längsnuten 20 auf, die zwischen sich einen Steg 22 bilden. Dieser verbindet eine Rückenleiste 24 mit dem übrigen Teil der Kopfleiste 18. In die Längsnuten 20 der Kopfleiste 18 wird ein Tragelement 26 eingesetzt, das zwei parallel verlaufende Schenkel 28 besitzt, die an ihren Enden jeweils durch einen integralen Verbindungssteg 32 miteinander verbunden sind. Die Schenkel 28 bilden zwischen sich einen Spalt 30, der im montierten Zustand des Tragelements 26 den Steg 22 aufnimmt.A wiper blade 10 owns wiper strip 12 with a wiper lip 14 which has a tipping foot 16 with a header 18 connected is. The header 18 has two lateral longitudinal grooves 20 up, a bridge between them 22 form. This connects a back bar 24 with the rest of the header 18 , In the longitudinal grooves 20 the header 18 becomes a support element 26 used, the two parallel legs 28 possesses, at their ends in each case by an integral connecting web 32 connected to each other. The thigh 28 form a gap between them 30 in the assembled state of the support element 26 the jetty 22 receives.

Das Tragelement 26 kann quer zur Längsrichtung 42 in Richtung auf die Wischlippe 14 montiert werden. Dazu ist die Rückenleiste 24 durch Aussparungen 36 in mehrere Teilstücke 38 unterteilt, wobei die Länge der Teilstücke 38 zweckmäßigerweise gleich der Länge der Aussparungen 36 ist. Das Tragelement 26 weist entsprechend den Teilstücken 38 dimensionierte Montagefenster 34 auf, die durch Vorsprünge 40 an den längs verlaufenden Schenkeln 28 des Tragelements 26 voneinander getrennt sind. Die Vorsprünge 40 bilden zwischen sich den Spalt 30.The support element 26 can be transverse to the longitudinal direction 42 in the direction of the wiper lip 14 to be assembled. This is the back bar 24 through recesses 36 in several parts 38 divided, with the length of the cuts 38 suitably equal to the length of the recesses 36 is. The support element 26 points according to the sections 38 dimensioned mounting window 34 on that by protrusions 40 on the longitudinal legs 28 of the support element 26 are separated from each other. The projections 40 form the gap between them 30 ,

Bei der Montage werden die in Längsrichtung 42 versetzt zu den Teilstücken 38 angeordneten Montagefenster 34 über die Teilstücke 38 in Richtung auf die Wischlippe 14 über die Teilstücke 38 geschoben. Danach wird das Tragelement 26 in Längsrichtung 42 verschoben, sodass die Vorsprünge 40 in die Längsnuten 20 unter die Teilstücke 38 der Rückenleiste 24 gelangen und somit in den Richtungen quer zur Längsrichtung 42 das Tragelement 26 verriegeln. Das Tragelement 26 kann aus Federblech in einem Stanz- und Biegeverfahren gefertigt werden. Es kann aber auch vorteilhafterweise aus Kunststoff in einem Spritzgießverfahren hergestellt werden.During assembly, the longitudinal direction 42 offset to the sections 38 arranged mounting window 34 over the cuts 38 in the direction of the wiper lip 14 over the cuts 38 pushed. Thereafter, the support element 26 longitudinal 42 moved so that the projections 40 in the longitudinal grooves 20 under the cuts 38 the back bar 24 arrive and thus in the directions transverse to the longitudinal direction 42 the support element 26 lock. The support element 26 can be made of spring steel in a punching and bending process. But it can also be advantageously made of plastic in an injection molding process.

Das Wischblatt 10 in der Ausführung nach 2 besitzt einen Spoiler 44, der einen parallel zum montierten Tragelement 26 verlaufenden Längskanal 46 mit einem flachen Querschnitt aufweist. Der Längskanal 46 dient zur Werkstoff- und Gewichtseinsparung und verbessert die Flexibilität des Spoilers 44. Außerdem kann er zur Aufnahme eines zusätzlichen Tragelements in Form einer Federschiene dienen.The wiper blade 10 in the execution after 2 has a spoiler 44 , one parallel to the mounted support element 26 extending longitudinal channel 46 having a flat cross-section. The longitudinal channel 46 It saves material and weight and improves the flexibility of the spoiler 44 , In addition, it can serve to receive an additional support element in the form of a spring rail.
