Abstract

The invention relates to a wiping device, in particular a wiping device for a motor vehicle pane, comprising a spoiler unit ( 22 a - 22 p ). According to the invention, said spoiler unit ( 22 a - 22 p ) is produced in a co-extrusion process.

First claim

What is claimed is:

1. A wiping device, with a spoiler unit ( 22 a - 22 p ) produced in a co-extrusion process, wherein the spoiler unit ( 22 a - 22 p ) has two separate harder spoiler part elements ( 34 a - 34 p ) separated from one another by an open gap along a wiping direction ( 88 a ) and a softer spoiler part element ( 32 a - 32 p ) coupled to each of the two harder spoiler part elements ( 34 a - 34 p ), and wherein each of the harder spoiler part elements ( 34 a - 34 p ) conceals a respective portion of the softer spoiler part element ( 32 a - 32 p ) along the wiping direction ( 88 a - 88 p ), so that the harder spoiler part elements ( 34 a - 34 p ) protect the softer spoiler part element from damage on opposite sides of the softer spoiler part element along the wiping direction ( 88 a - 88 p ), and further comprising a separate holding element ( 12 a - 12 p ) coupled to the spoiler unit ( 22 d - 22 p ), wherein the holding element ( 12 a - 12 p ) includes a longitudinal guide channel ( 14 a ) sized to receive a spring element ( 16 a - 16 p ) along a longitudinal direction, wherein the longitudinal guide channel ( 14 a ) is spatially offset from the open gap, such that the entire spoiler unit ( 22 a - 22 p ) is spaced above the longitudinal guide channel ( 14 a ) along a vertical direction ( 102 a ) that is perpendicular to both the longitudinal direction and the wiping direction ( 88 a ), wherein the holding element ( 12 a - 12 p ) includes side walls ( 52 a , 54 a ) and channel walls ( 36 a , 38 a ) that extend perpendicular to the side walls ( 52 a , 54 a ), wherein the side walls ( 52 a , 54 a ) and the channel walls ( 36 a , 38 a ) define boundaries of the longitudinal guide channel ( 14 a ) and are configured to guide the spring element ( 16 a - 16 p ) in the longitudinal guide channel ( 14 a ), wherein the holding element ( 12 a - 12 p ) includes two L-shaped fixing elements ( 18 a , 20 a ) that extend from the channel walls ( 36 a , 38 a ), wherein the fixing elements include upper portions that extend along the wiping direction, wherein the upper portions include free ends ( 24 a , 26 a ) that are received in the spoiler unit ( 22 a - 22 p ), wherein the free ends face away from one another, and wherein a distance between the free ends along the wiping direction defines a width of the holding element that is greater than a width of any other portion of the holding element along the wiping direction.

2. The wiping device as claimed in claim 1 , wherein the softer spoiler part element ( 32 a - 32 i ; 32 n ) has a longitudinal channel ( 82 a - 82 i ; 82 n ) with a triangular cross section.

3. The wiping device as claimed in claim 1 , further comprising a spring element ( 16 a - 16 p ) disposed in the longitudinal guide channel ( 14 a - 14 p ), wherein the entire spring element ( 16 a - 16 p ) is spaced below the spoiler unit ( 22 a - 22 p ) along the vertical direction ( 102 a ).

4. The wiping device as claimed in claim 1 , wherein the spoiler unit ( 22 d - 22 h ; 22 n ) lies at least partly laterally on the holding element ( 12 d - 12 h ; 12 n ) in the region of the longitudinal guide channel ( 14 d - 14 h ; 14 n ).

5. The wiping device as claimed in claim 1 , further comprising a wiper blade connected to the holding element on a side of the holding element opposite the spoiler unit.

6. The wiping device as claimed in 1 , wherein the spoiler unit ( 22 a - 22 p ) is symmetrical about an axis ( 102 a - 102 p ) that extends perpendicular to the wiping direction.

7. The wiping device as claimed in claim 6 , wherein interfaces between the harder spoiler part elements ( 34 a - 34 p ) and the softer spoiler part element ( 32 a - 32 p ) define planes that extend at oblique angles relative to the wiping direction.

8. The wiping device as claimed in claim 7 , wherein the planes form a “V”-shape.

9. The wiping device as claimed in claim 1 , wherein a plane extends along the wiping direction ( 88 a - 88 p ), wherein the plane passes through one of the harder spoiler part elements ( 34 a - 34 p ), then through the softer spoiler part element ( 32 a - 32 p ), and then through the other harder spoiler part element ( 34 a - 34 p ) moving along the wiping direction ( 88 a - 88 p ).

10. The wiping device as claimed in claim 9 , wherein the spoiler unit ( 22 a - 22 p ) is symmetrical about an axis ( 102 a - 102 p ) that is perpendicular to the plane.

11. The wiping device as claimed in claim 1 , wherein the wiping direction ( 88 a - 88 p ) extends through a portion of each of the harder spoiler part element ( 34 a - 34 p ) and the softer spoiler part element ( 32 a - 32 p ).
