Abstract

The invention relates to a wiping device, in particular a wiping device for a motor vehicle pane, comprising a retaining unit ( 10 a - 10 e ) that has a retaining element ( 12 a - 12 e ) with a longitudinal guide channel ( 14 a - 14 e ) for guiding a spring element ( 16 a - 16 e ), and comprising a spoiler unit ( 22 a - 22 e ). According to the invention, the spoiler unit ( 22 a - 22 e ) lies at least partially at the side of the retaining element ( 12 a - 12 e ) in the region of the longitudinal guide channel ( 14 a - 14 e ).

First claim

What is claimed is:

1. A wiping device, comprising a retention unit ( 10 a - 10 e ) which has a retention element ( 12 a - 12 e ) having a longitudinal guiding channel ( 14 a - 14 e ) for guiding a resilient element ( 16 a - 16 e ) along a longitudinal plane, and a wind deflector unit ( 22 a - 22 e ), characterized in that the wind deflector unit ( 22 a - 22 e ) is at least partially in lateral abutment with the retention element ( 12 a - 12 e ) in a region of the longitudinal guiding channel ( 14 a - 14 e ), wherein the wind deflector unit ( 22 a ) includes a first support web ( 24 a ) which is provided to transmit pressing forces of the wind deflector unit ( 22 a ) directly to the retention unit ( 10 a ) along a direction extending from the wind deflector unit ( 22 a ) toward the longitudinal guide channel ( 14 a - 14 e ) and perpendicular to the longitudinal plane, and wherein the retention unit ( 10 a ) includes two first protrusions ( 90 a ) that define a first channel for receiving the first support web ( 24 a ), and wherein the wind deflector unit ( 22 a ) includes a second support web ( 26 a ) which is provided to transmit pressing forces of the wind deflector unit ( 22 a ) directly to the retention unit ( 10 a ) along a direction extending from the wind deflector unit ( 22 a ) toward the longitudinal guide channel ( 14 a - 14 e ) and perpendicular to the longitudinal plane, wherein the retention unit ( 10 a ) includes two second protrusions ( 92 a ) that define a second channel for receiving the second support web ( 26 a ), wherein the two first protrusions ( 90 a ) and the two second protrusions ( 92 a ) define four separately spaced protrusions that are spaced apart from one another by gaps along a wiping direction ( 18 a ) of the wiping device, the wiping direction ( 18 a ) being parallel to the longitudinal plane, wherein each of the two first protrusions ( 90 a ) and the two second protrusions ( 92 a ) extends upwardly in a direction perpendicular to and away from the longitudinal plane, and wherein each of the first support web ( 24 a ) and the second support web ( 26 a ) extends downwardly in a direction perpendicular to and toward the longitudinal plane.

2. The wiping device as claimed in claim 1 , characterized in that the wind deflector unit ( 22 a - 22 e ) in the region of the longitudinal guiding channel ( 14 a - 14 e ) is at least partially in abutment with a side of the retention element ( 12 a - 12 e ) facing a wiper blade ( 40 a - 40 e ).

3. The wiping device as claimed in claim 1 , characterized in that the wind deflector unit ( 22 a ; 22 b ) is produced in a co-extrusion method.

4. The wiping device as claimed in claim 1 , characterized in that the wind deflector unit ( 22 a - 22 e ) has two wind deflector part-elements ( 32 a - 32 e ; 34 a - 34 e ) of different hardnesses.

5. The wiping device as claimed in claim 4 , characterized in that a harder wind deflector part-element ( 34 a ) laterally terminates the wind deflector unit ( 22 a ).

6. The wiping device as claimed in claim 1 , wherein the two first protrusions ( 90 a ) are separated from the two second protrusions ( 92 a ) by a longitudinal opening ( 84 a ) in the retention element ( 12 a ).

7. The wiping device as claimed in claim 1 , further comprising a wiper blade ( 40 a - 40 e ) coupled to the retention element ( 12 a - 12 e ), wherein the longitudinal guide channel ( 14 a - 14 e ) is disposed between the wiper blade ( 40 a - 40 e ) and each of the two first protrusions ( 90 a ), the two second protrusions ( 92 a ), the gaps, the first support web ( 24 a ), and the second support web ( 26 a ).

8. The wiping device as claimed in claim 7 , wherein the retention element ( 12 a - 12 e ) also includes channel walls ( 36 a , 38 a ) that extend inwardly toward each other and adjoin the longitudinal guide channel ( 14 a ) at a side remote from the wiper blade, wherein the two first protrusions ( 90 a ) extend upwardly from one of the channel walls ( 36 a ) and wherein the two second protrusions ( 92 a ) extend upwardly from the other of the channel walls ( 38 a ).

9. The wiping device as claimed in claim 8 , further comprising a resilient element ( 16 a - 16 e ) disposed within the longitudinal guide channel ( 14 a - 14 e ), wherein the channel walls extend above the resilient element ( 16 a - 16 e ) that is disposed within the longitudinal guide channel ( 14 a - 14 e ), and wherein ends of the channel walls are spaced apart and partially define a longitudinal opening ( 84 a ) in the retention element ( 12 a - 12 e ).

10. The wiping device as claimed in claim 9 , wherein the retention element ( 12 a - 12 e ) also includes an intermediate wall ( 56 a ) between the longitudinal guide channel ( 14 a - 14 e ) and the wiper blade ( 40 a - 40 e ).
