Description
Technical Field
The present invention relates to a system comprising a wiper blade and a wiper arm according to the types of independent claim 1.
Background
The wiper blade is connected to the wiper arm via a wiper blade adapter in order to achieve the mounting and replacement of the wiper blade at the vehicle. The wiper blade adapter serves to transmit a lateral guiding force from the wiper arm to the wiper blade during a wiping movement. Furthermore, wiper blade adapters often perform a rotational movement, so that the wiper blade can adapt to tilting and bending of the pane during the wiping movement over the curvature of the pane. Embodiments are known here in which the wiper blade adapter comprises a swivel hinge, but also in which the connection to the wiper arm takes place at a shaft which enables a swivel and which can be detachably mounted on the receiving element of the wiper arm. In a final embodiment, the pivot pin mounted on the wiper arm is moved as a shaft into the receiving opening of the wiper blade adapter in the lateral direction.
Wiper blades are also known in the prior art which have a nozzle for applying a cleaning fluid to a pane and in which a fluid supply line can lead to the wiper arm via a wiper blade adapter or is arranged at the wiper blade adapter and can be connected in a detachable manner between the wiper arm and the wiper blade adapter.
It is also known in the prior art to provide electrical connections to the wiper blade, for example for heating to prevent freezing of the cleaning fluid. For this purpose, embodiments are known in which a plug connection is provided at the wiper blade adapter.
A device for a windscreen wiper system is known from US 2014331437A1, comprising a wiper blade adapter with a wiper blade, which wiper blade adapter effects a rotational movement between a wiper arm and a wiper blade, wherein the wiper blade adapter is provided for effecting a hydraulic and electrical connection of the wiper blade to a connection point of the wiper arm.
Disclosure of Invention
The system comprising a wiper blade and a wiper arm with the features of independent claim 1 has the advantage that the separation of the joint connection for the cleaning fluid is done on one side and the separation of the joint connection for the electricity is done on the other side. A relatively flat design can thus be achieved, for example, because the supply connections for the electric and cleaning fluid can often be arranged only one above the other due to the relatively narrow width of the wiper blade and thus of the wiper blade adapter. This can be accomplished at different points and thus with a smaller overall height by the separation. In principle, the distance between the connection point for the cleaning fluid or water and the electrical connection point is also advantageous. The risk that liquid can come out of one of the connection points and can always be present in the electrical connection is that no complete tightness against moisture and water is present. In addition, an advantageous and easy installation by the customer is possible, since the sliding contact surface automatically contacts after the wiper arm and wiper blade are connected and, if appropriate, after the connection of the joint connection for the cleaning fluid, when the wiper blade and wiper arm are connected into the operating position.
Advantageous developments and improvements of the features specified in the independent claims are also achieved by the measures specified in the dependent claims.
The joint connection for the cleaning fluid is advantageously arranged at the lower part of the wiper blade adapter.
The fluid line of the wiper arm can be connected to the joint connection and can be designed to be elastic, in particular a hose line.
In one embodiment, the joint connection is oriented upwards in the direction of the wiper arm.
The wiper blade is advantageously a flat-beam wiper blade with a support element exerting a preload in the direction of the pane, a wiper strip and a cover element, which covers the support element on the upper side, wherein the cover element can have a spoiler.
In an advantageous embodiment, the wiper blade adapter is connected to the support element and the separate supply adapter is connected to the support element.
A portion of the covering element can be arranged between the wiper blade adapter and the supply adapter.
Drawings
Embodiments are shown in the drawings and will be explained in more detail in the following description.
FIG. 1 shows a wiper blade with a wiper arm mounted; and is also provided with
Fig. 2 shows an exploded view of the elements of fig. 1.
Detailed Description
Fig. 1 shows a wiper blade 1 with a wiper arm 2 mounted thereon in a partial manner. A wiper blade adapter 3, which is formed by an upper part 4 and a lower part 5 connected to a supporting element of the wiper blade 1, is used for fixing the wiper arm 2. The cleaning fluid is fed via a fluid line 6 through the wiper arm 2, which is distributed via the wiper blade adapter 3 to a fluid line 7 in the wiper blade 1, which has nozzle openings for spraying the cleaning fluid 8.
The wiper blade 1 further has a covering element 9 in the form of a spoiler 10. The supply adapter 12 is arranged at the wiper blade 1 by means of a portion 11 of the cover element 9, separately and at a distance from the wiper blade adapter 3. The supply adapter 12 has a contact surface 13 which forms a sliding contact with a wiper arm contact surface 18.
Fig. 2 shows an exploded view of the elements of fig. 1. The wiper blade 1 relates to a flat-beam wiper blade 14 with a support element 15 which applies a preload force to the wiper strip 16 oriented in the direction of the pane, not shown here, in such a way that, during a wiping movement, the wiper strip 16 always rests against the pane when moving over the curvature of the pane. The electrical heating element 17 prevents the water of the cleaning fluid from freezing at sub-zero temperatures. The cover element 9 is mounted to the support element 15. A portion 11 of the cover element 9 is arranged between and separates the wiper blade adapter 3, which is formed by the upper part 4 and the lower part 5, and the supply adapter 12 with the contact surface 13. The fluid line 7 passes through the cover element 9, the lower part 5 and the supply adapter 12, through the nozzle opening of which the cleaning fluid 8 can come out. The wiper arm 2 has a wiper arm contact surface 18.
