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 wiping device has at least one undercut ( 18 a - 18 e, 20 a - 20 e ) that is provided in order to interlockingly connect the spoiler unit ( 22 a - 22 e ) to the retaining element ( 12 a - 12 e ) in a wiping direction ( 24 a - 24 e ).

First claim

What is claimed is:

1. A wiping device, comprising a retaining unit ( 10 a - 10 e ) which 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 ), the wiping device further including a spoiler unit ( 22 a - 22 e ), wherein the retaining unit ( 12 a - 12 e ) includes an undercut ( 18 a - 18 e , 20 a - 20 e ) which is provided to connect the spoiler unit ( 22 a - 22 e ) positively to the retaining element ( 12 a - 12 e ) in a wiping direction ( 26 a - 26 e ), wherein the undercut ( 18 a - 18 e , 20 a - 20 e ) has a C-shaped contour defined by two arms that form an opening in the retaining element ( 12 a - 12 e ) along the wiping direction ( 26 a - 26 e ), wherein the opening receives the spoiler unit ( 22 a - 22 e ), wherein the retaining element ( 12 a - 12 e ) further includes a track ( 70 a - 70 e ) for guiding a wiper strip ( 40 a - 40 e ), the track ( 70 a - 70 e ) including a wall ( 66 a - 66 e ) with a surface that extends at an oblique angle relative to a plane that is perpendicular to a plane of symmetry of the wiping device, and wherein the surface of the wall also extends parallel to a further surface ( 30 a - 30 e ) along a bottom of one of the two arms.

2. The wiping device as claimed in claim 1 , characterized in that the surface of the wall ( 66 a - 66 e ) of the retaining element ( 12 a - 12 e ) also extends parallel to a bottom surface of the spoiler unit ( 22 a - 22 e ).

3. The wiping device as claimed in claim 1 , characterized in that the spoiler unit ( 22 a - 22 c ) bears laterally against the retaining element ( 12 a - 12 c ).

4. The wiping device as claimed in claim 1 , further comprising a wiper strip interlocking with the retaining element.

5. The wiping device as claimed in claim 4 , wherein the wiper strip is located on a side of the retaining element opposite the spoiler unit.
