Description

Title of the invention: Windshield wiper blade Field of invention

[0001] The present invention relates to a windshield wiper blade comprising a wiper blade adapter for connection to a wiper arm, the wiper blade adapter comprising a removable primary connection link for a supply line supplying cleaning fluid or current, the supply line passing through the wiper blade adapter into the wiper blade. State of the art

[0002] The wiper blade is connected to the wiper arm by a wiper blade adapter to enable the wiper blade to be mounted on the vehicle and replaced. The wiper blade adapter serves, among other things, to transmit the lateral guiding forces of the wiper arm during the wiping movement and, in many embodiments, allows a pivoting movement to be provided so that the wiper blade can adapt to the inclination and curvature of the window during the wiping movement. Thus, embodiments of parts are known in which the wiper blade adapter comprises a pivot joint, but also embodiments in which the connection with the wiper arm is made by an axis allowing rotation; the receiving elements of the wiper arm are installed in a removably manner.

[0003] According to the state of the art, windscreen wiper blades are also known which are equipped with nozzles for distributing the cleaning liquid onto the window; the windscreen wiper blade adapter is traversed by liquid lines to the windscreen wiper arm, being removably connected to the windscreen wiper blade adapter.

[0004] Similarly, in the state of the art, it is known to provide electrical supply lines for the wiper blade, for example, for heating, as protection against freezing of the cleaning liquid. Thus, embodiments are known in which the wiper blade adapter has a connection via a connector.

[0005] According to US 2014 331437 A1, a wiper blade system arrangement with a wiper blade adapter is known which allows a rotational movement between the wiper arm and the wiper blade; the wiper blade adapter has a hydraulic connection and / or an electrical connection for the wiper blade with a connection point of the wiper arm.

[0006] Document US 2015 175131 A1 describes an electrical connection member for a windshield wiper blade comprising a connector and which is clipped securely to the wiper blade adapter for its connection with the wiper arm. According to another known embodiment, a hydraulic connection member is provided between the wiper arm and the wiper blade; this member is fixed to the wiper blade adapter. The electrical connection member is located below the hydraulic connection member and these two connection members form an angle with respect to the horizontal direction from one side, in the longitudinal direction of the wiper blade, with the wiper blade adapter.

[0007] Document DE 10 2013 104 900 A1 describes a connection between the wiper arm and a wiper blade adapter. According to this document, the hydraulic lines are connected by connections topped by an electrical connector. Both the electrical line and the hydraulic lines pass through the wiper blade adapter into the wiper blade.

[0008] Description and advantages of the invention

[0009] The invention relates to a windscreen wiper blade comprising a wiper blade adapter for connection to a windscreen wiper arm, the wiper blade adapter comprising a removable primary connection link for a supply line supplying cleaning liquid or current, the supply line passing through the wiper blade adapter to arrive in the wiper blade, this wiper blade being characterized in that a secondary connection link is provided, separate from the wiper blade adapter and removable, for the cleaning liquid or current, the primary connection link being provided for the cleaning liquid and the secondary connection link being provided for the current or vice versa.

[0010] This wiper blade has the advantage that the separation of the connection connections for the cleaning fluid supply line is on one side and that for the current is on the other side. Thus, the cleaning fluid passes either via the primary connection connection and the wiper blade adapter to arrive at the wiper blade or via the secondary connection connection. The current is then supplied via the other connection connection. This allows, for example, to have a flatter construction because due to the relatively narrow width of the wiper blade and thus of the wiper blade adapter, the supply connections for the current and the cleaning fluid are often superimposed. However, according to the invention, this is not done at the same point of the wiper blade adapter and the connection to the wiper arm.Moreover, the supply lines can be at a slight angle to the horizontal direction and pass through different places in the wiper blade. In addition, there is a separation. fundamentally advantageous, in the space between the current lines, i.e. the electrical connections and the cleaning fluid, i.e. the water. Finally, the installation on the wiper arm is made easier for the customer. One of the two connection connections is made, for example, in the form of a connection for the current and a free cable that is first brought together before connecting the wiper arm and the wiper blade via the wiper blade adapter.

[0011] Advantageously, according to another characteristic, the wiper blade is a flat beam wiper blade with a support element exerting a prestressing force towards the window, a wiper blade and a cover element covering the upper side of the support element, the cover element having a deflector.

[0012] According to another advantageous feature, the wiper blade adapter is connected to the support element and is separated from it in a connecting element which, instead of the cover element, is provided with the support element on the upper side along the length of the connecting element, covered, and which has the secondary connecting connection.

[0013] Flat beam wiper blades very often have an upper cover which is in particular designed in the form of a deflector to exert a supporting force under the effect of the circulating wind. A segment of this embodiment can replace the cover or even be provided in a recess of this cover for the connecting element.

[0014] According to an advantageous development, an intermediate element is provided between the wiper blade adapter and the connecting element, this element covering the top of the support element according to the length of the intermediate element in place of the covering element.

[0015] Advantageously, the primary connection link is provided for the cleaning liquid and the secondary connection link is provided for the current.

[0016] According to an advantageous development, the primary connection connection for the cleaning liquid is on the wiper blade adapter at a small angle to the horizontal direction, in particular in an angular range between 5° and 15° so that the secondary connection connection is a plug-in connection for the current under the supply lines, in the extension of the primary connection connection. This makes it possible, for example, to first make the electrical connection connection and then to fix the wiper blade to the wiper arm.

[0017] The connection link for the current can be made at the same angle relative to the horizontal direction as the primary connection link.

[0018] According to a development, the wiper blade adapter comprises pivots oriented transversely to the longitudinal direction of the wiper blade for connection with the wiper arm.

[0019] In the case of a wiper arm for connecting a wiper blade of the type described above, there is a connecting element for the secondary connection connection, in particular a plug-in connection by a power cable which is connected so as to be free in movement with the wiper arm. This solution has the advantage of having a separate connection between the electrical connection or electrical power connection, when mounting the wiper blade on the wiper arm.

[0020] According to an advantageous development, the secondary connecting link is located under the wiper arm upstream of the end segment of the wiper arm provided for connection to the wiper blade adapter. Presentation of the drawings

[0021] The present invention will be described below, using an exemplary embodiment of a windscreen wiper blade shown in the attached drawings in which:

The wiper arm 3 is provided with a supply line 4 for cleaning liquid. The connecting connection 5 serves as a secondary connecting connection 6 for the current and supplies the wiper blade 1 via a connecting element 7. Between the wiper blade adapter 2 and the connecting element 7, there is an intermediate element 8. The intermediate element 8 and the connecting element 7 replace, according to their respective length, a cover element 9 with an integrated deflector 10.To clean the portion of the window upstream of the wiper blade 11, cleaning liquid 12 may be dispensed through nozzles supplied by the supply line 4 and channels 13 in the wiper blade 1 supplying the cleaning liquid.

[0026] Figure 2 shows the detail of Figure 1 without the covering elements and with the end of the wiper arm 3 limited to a simple part. The secondary connection link 6 with the connection link 5 which supplies the current by the current line 14 through the connection element 7 to the heating 15 of the wiper blade 1, is surmounted by the supply line 4 supplying the liquid cleaning fluid, integrated in the wiper arm 3. A primary connecting link 16 of the wiper blade adapter 2 can supply the cleaning fluid to the wiper blade 1 according to the present exemplary embodiment.

[0027] Figure 2 further shows a pivot 17 used for fixing the wiper arm 3.

[0028] The power supply 4 with the primary connection link 16 makes a small angle by relative to the horizontal direction as the connecting connection 5. Both the primary connecting connection 16 for the cleaning liquid and the secondary connecting connection 6 for the current are each made in duplicate in the present example.
