Abstract

The invention relates to a wiping device, in particular a wiping device for a motor vehicle pane, comprising a spring element ( 16 a - 16 g ), a retaining unit ( 10 a - 10 g ) that has a retaining element ( 12 a - 12 g ) with a longitudinal guide channel ( 14 a - 14 g ) for guiding the spring element ( 16 a - 16 g ), and comprising a spoiler unit ( 22 a - 22 g ). According to the invention, the spoiler unit ( 22 a - 22 g ) has at least one supporting rib ( 72 a - 72 g , 74 a - 74 g ) that extends from an inner contour of the spoiler ( 22 a - 22 g ) in the form of a projection and that is provided in order to transmit the downforces that occur from the spoiler ( 22 a - 22 g ) to the retaining unit ( 10 a - 10 g ).

First claim

What is claimed is:

1. A wiper device, comprising a spring element ( 16 a - 16 g ) and a retaining unit ( 10 a - 10 g ), which retaining unit comprises a retaining element ( 12 a - 12 g ) with a longitudinal guide channel ( 14 a - 14 g ) guiding the spring element ( 16 a - 16 g ), the retaining element ( 12 a - 12 g ) further including two channel walls ( 36 a - 36 d , 38 a - 38 d ) wrapped around sides of the spring element ( 16 a - 16 g ), wherein each channel wall ( 36 a - 36 d , 38 a - 38 d ) includes a first portion that extends over and contacts a top of the spring element ( 16 a - 16 g ), a second portion that extends along and contacts a side of the spring element ( 16 a - 16 g ), and a third portion that extends under and contacts a bottom of the spring element ( 16 a - 16 g ), and the wiper device comprising a wind deflector unit ( 22 a - 22 g ) including two supporting webs ( 72 a - 72 g , 74 a - 74 g ) extending by prolongations from an inner contour of the wind deflector unit ( 22 a - 22 g ), which supporting webs transfer contact pressing forces which occur from the wind deflector unit ( 22 a - 22 g ) directly onto either the first portions of the channel walls ( 36 a - 36 d , 38 a - 38 d ) or directly onto the spring element ( 16 a - 16 g ), wherein a further channel is disposed between the longitudinal guide channel ( 14 a - 14 g ) and the wind deflector unit ( 22 a - 22 g ), and wherein the two supporting webs ( 72 a - 72 g , 74 a - 74 g ) divide the further channel into three separate longitudinal channels above the retaining element ( 12 a - 12 g ).

2. The wiper device as claimed in claim 1 , characterized in that the wind deflector unit ( 22 a - 22 g ) is produced using a coextrusion process.

3. The wiper device as claimed in claim 2 , characterized in that the wind deflector unit ( 22 a - 22 g ) comprises two wind deflector subcomponents ( 32 a - 32 g , 34 a - 34 g ) of different hardnesses.

4. The wiper device as claimed in claim 3 , characterized in that a harder wind deflector subcomponent ( 34 a - 34 g ) closes the wind deflector unit ( 22 a - 22 g ) laterally.

5. The wiper device as claimed in claim 4 , characterized in that the retaining element ( 12 a - 12 g ) has a longitudinal opening ( 84 a - 84 g ), which opens the longitudinal guide channel ( 14 a - 14 g ) towards the wind deflector unit ( 22 a - 22 g ) at least partially.

6. The wiper device as claimed in claim 5 , wherein the longitudinal opening ( 84 a - 84 g ) forms part of the further channel.

7. The wiper device as claimed in claim 3 , characterized in that a softer wind deflector subcomponent ( 32 a - 32 g ) comprises a longitudinal channel ( 82 a - 82 g ) which includes a triangular cross-section.

8. The wiper device as claimed in claim 1 , characterized in that the wind deflector unit ( 22 b - 22 g ) bears against the retaining element ( 12 b - 12 g )at least partially laterally in a region of the longitudinal guide channel ( 14 b - 14 g ).

9. The wiper device as claimed in claim 1 , wherein the wind deflector unit ( 22 a - 22 g ) comprises two wind deflector subcomponents ( 32 a - 32 g , 34 a - 34 g ) of different hardnesses, wherein a harder wind deflector subcomponent( 34 a - 34 g ) closes the wind deflector unit ( 22 a - 22 g ) laterally, and wherein the retaining element ( 12 a - 12 g ) has a longitudinal opening ( 84 a - 84 g ), which opens the longitudinal guide channel ( 14 a - 14 g ) towards the wind deflector unit ( 22 a - 22 g ) at least partially.

10. The wiper device as claimed in claim 1 , wherein the longitudinal guide channel ( 14 a - 14 g ) opens into the further channel, and wherein the further channel extends entirely axially through the wiper device along a longitudinal direction of the wiper device.

11. The wiper device as claimed in claim 1 , wherein a width of each of the two supporting webs ( 72 a - 72 g , 74 a - 74 g ) is constant moving along a direction away from the inner contour of the wind deflector unit ( 22 a - 22 g ).

12. The wiper device as claimed in claim 1 , wherein the first portions of the channel walls ( 36 a - 36 d , 38 a - 38 d ) are separated from one another by a gap.
