Abstract

The invention relates to a wiping device, in particular a wiping device for a motor vehicle pane, comprising a retaining element ( 10 a - 10 f ) with at least one longitudinal guide channel ( 18 a - 18 f ) for guiding at least one spring element ( 20 a - 20 f ). According to the invention, the retaining element ( 10 a - 10 f ) has at least three fixing cavities ( 26 a - 26 f, 28 a - 28 f, 30 a - 30 f, 32 a ) that are offset in the longitudinal direction ( 22 a - 22 f ) and that are provided in order to interlock with a wiper blade adapter ( 12 a - 12 f ).

First claim

What is claimed is:

1. A wiper device, comprising a retaining element ( 10 a - 10 f ) including at least one longitudinal guide channel ( 18 a - 18 f ) for guiding at least one spring element ( 20 a - 20 f ), characterized in that the retaining element ( 10 a - 10 f ) comprises at least three fastening recesses ( 26 a - 26 f , 28 a - 28 f , 30 a - 30 f , 32 a ) offset in a longitudinal direction ( 22 a - 22 f ), the wiper device further comprising a wiper blade adapter ( 12 a - 12 f ) interlocked to the retaining element ( 10 a - 10 f ) in the fastening recesses ( 26 a - 26 f , 28 a - 28 f , 30 a - 30 f , 32 a ), wherein the fastening recesses ( 26 a , 28 a , 30 a , 32 a ) are arranged at least partially in a wind deflector fastening element ( 50 a , 52 a ) of the retaining element ( 10 a - 10 f ), wherein the wind deflector fastening element ( 50 a , 52 a ) interlocks with a wind deflector element ( 14 a ) of the wiper device.

2. The wiper device as claimed in claim 1 , further comprising a wiper strip fastened to the retaining element, wherein the wiper blade adapter ( 12 a ) comprises at least one latching element ( 40 a , 42 a ), which bears laterally against the retaining element ( 10 a ) in a mounted state on a side facing the wiper strip ( 46 a , 48 a ) and is provided to prevent movement of the wiper blade adapter ( 12 a ) relative to the retaining element ( 10 a ) in a vertical direction ( 44 a ).

3. The wiper device at least as claimed in claim 1 , characterized in that the wiper blade adapter ( 12 b - 12 f ) comprises at least one latching element ( 40 b - 40 f , 42 b - 42 f ), which bears laterally against the retaining element ( 10 b - 10 f ) in a mounted state and is provided to prevent movement of the wiper blade adapter ( 12 b - 12 f ) relative to the retaining element ( 10 b - 10 f ) in a longitudinal direction ( 22 b - 22 f ) of the retaining element ( 10 b - 10 f ).

4. The wiper device as claimed in claim 3 , characterized in that the latching element ( 40 b - 40 f , 42 b - 42 f ) bears laterally against the spring element ( 20 b - 20 f ) in a mounted state and is provided to avoid movement of the wiper blade adapter ( 12 b - 12 f ) relative to the spring element ( 20 b - 20 f ) in a longitudinal direction ( 22 b - 22 f ).

5. The wiper device at least as claimed in claim 3 , characterized in that the latching element ( 40 b - 40 d , 42 b - 42 d ) is provided to be deflected at least substantially in a wiping direction ( 24 b - 24 d ) in an assembly.

6. The wiper device at least as claimed in claim 3 , characterized in that the latching element ( 40 c ; 40 f , 42 c ; 42 f ) comprises at least two latching arms ( 88 c ; 88 f , 90 c ; 90 f ) which are connected to the wiper blade adapter ( 12 c ; 12 f ) and are provided to be resiliently deflected.

7. The wiper device as claimed in claim 1 , further comprising a wiper strip fastened to the retaining element.

8. The wiper device as claimed in claim 1 , further comprising a wind deflector element interlocking with the wind deflector fastening element ( 50 a , 52 a ).

9. The wiper device as claimed in claim 1 , wherein the wind deflector fastening element ( 50 , 52 a ) has an L-shaped cross-section.

10. The wiper device as claimed in claim 1 , wherein the wind deflector fastening element ( 50 a , 52 a ) is provided to releasably interlock with the wind deflector element ( 14 a ), such that the wind deflector ( 14 a ) is moved along the longitudinal direction ( 22 a - 22 f ) into the wind deflector fastening element ( 50 a , 52 a ) during an assembly.

11. The wiper device as claimed in claim 1 , wherein the wind deflector fastening element ( 50 a , 52 a ) is a first wind deflector fastening element ( 50 a , 52 a ), and wherein the retaining element ( 10 a - 10 f ) includes a second wind deflector fastening element ( 50 a , 52 a ).

12. The wiper device as claimed in claim 1 , wherein free ends of the first and second wind deflector fastening elements ( 50 a , 52 a ) face in opposite directions.

13. The wiper device as claimed in claim 1 , wherein the longitudinal guide channel ( 18 a - 18 f ) is spatially offset from the wind deflector fastening element ( 50 a , 52 a ) along a vertical direction ( 44 a ), wherein the vertical direction ( 44 a ) is perpendicular to the longitudinal direction ( 22 a - 22 f ) and to a wiping direction ( 24 a - 24 f ).

14. The wiper device as claimed in claim 1 , wherein the wiper blade adapter ( 12 a - 12 f ) includes bridge webs ( 34 a ) that interlock with the fastening recesses ( 26 a - 26 f , 28 a - 28 f , 30 a - 30 f , 32 a ).
