Abstract

The invention relates to a wiper blade adapter system with a wiper blade adapter unit (10) and at least two differently formed connecting elements (12, 14, 16), wherein, in a mounted state, the wiper blade adapter unit (10) is coupled to one of the at least two connecting elements (12, 14, 16). According to the invention, the wiper blade adapter unit (10) comprises a transmission unit (20) which is provided to release a coupling between the at least one connecting element (12, 14, 16) and the wiper blade adapter unit (10) during a detachment process.

First claim

What is claimed is:

1. A wiper blade adapter system comprising a wiper blade adapter unit ( 10 ) and at least two differently formed connecting elements ( 12 , 14 , 16 ), wherein, in a mounted state, the wiper blade adapter unit ( 10 ) is coupled to one of the at least two connecting elements ( 12 , 14 , 16 ), wherein each of the connecting elements ( 12 , 14 , 16 ) includes an elastically deflectable side wall ( 62 , 64 ), wherein the wiper blade adapter unit ( 10 ) comprises a transmission unit ( 20 ) having a ramp surface ( 24 ) which is configured to deflect the elastically deflectable side wall ( 62 , 64 ) laterally outwardly to release a coupling between the at least one connecting element ( 12 , 14 , 16 ) and the wiper blade adapter unit ( 10 ) during a detachment process, wherein the wiper blade adapter unit ( 10 ) further comprises a coupling unit ( 18 ) which is a separate element from the transmission unit and which, in an assembly process, is configured to be coupled to one of the at least two connecting elements ( 12 , 14 , 16 ) by an end user, wherein the coupling unit ( 18 ) and the connecting elements ( 12 , 14 , 16 ) are arranged such that to install one of the connecting elements onto the wiper blade adapter unit ( 10 ), the connecting element is configured to be pressed down over the coupling unit, and the coupling unit is configured to force the elastically deflectable side wall laterally outwardly.

2. The wiper blade adapter system according to claim 1 , characterized in that the coupling unit ( 18 ) has at least one first connecting link guide ( 32 ) which is configured to guide one of the at least two connecting elements ( 12 , 14 , 16 ).

3. The wiper blade adapter system according to claim 2 , characterized in that at least the first connecting link guide ( 32 ) has a curvature.

4. The wiper blade adapter system according to claim 2 , characterized in that at least one connecting element ( 12 , 14 , 16 ) of the at least two connecting elements ( 12 , 14 , 16 ) has at least one first guide element ( 92 , 94 ) which is configured to be guided in at least the first connecting link guide ( 32 , 96 ).

5. The wiper blade adapter system according to claim 1 , characterized in that the coupling unit ( 18 ) comprises at least one first coupling element ( 22 ) which, in a mounted state, abuts in a form-fitting manner against one of the at least two connecting elements ( 12 , 14 , 16 ) and is configured to prevent the connecting element ( 12 , 14 , 16 ) from releasing from the wiper blade adapter unit ( 10 ).

6. The wiper blade adapter system according to claim 5 , characterized in that at least the first coupling element ( 22 ) has a curved bearing surface ( 74 ) which is configured to pivotably support at least one of the connecting elements ( 12 , 14 , 16 ) in a mounted state.

7. The wiper blade adapter system according to claim 5 , characterized in that at least the first coupling element ( 22 ) is formed from an at least substantially cylindrical fastening element ( 84 ).

8. The wiper blade adapter system according to claim 7 , characterized in that the fastening element ( 84 ) comprises a longitudinal recess ( 86 ).

9. The wiper blade adapter system according to claim 5 , characterized in that at least the first coupling element ( 22 ) is formed from a sleeve element ( 88 ).

10. The wiper blade adapter system of claim 5 , wherein at least one of the elastically deflectable side walls includes a beveled interior surface configured to come into abutment with the at least one first coupling element during the assembly process.

11. The wiper blade adapter system according to claim 1 , characterized by at least three differently formed connecting elements ( 12 , 14 , 16 ) which are configured for coupling to different types of wiper arm adapters ( 200 , 202 , 204 , 206 , 208 , 210 , 212 ).

12. The wiper blade adapter system according to claim 1 , characterized in that at least the first elastically deflectable side wall ( 62 , 64 ) comprises a transverse recess ( 36 , 76 , 90 ) in which the coupling unit ( 18 ) at least partially engages in a mounted state.

13. The wiper blade adapter system according to claim 1 , characterized in that the at least two differently formed connecting elements ( 12 , 14 , 16 ) are configured in each case for coupling to different types of wiper arm adapters ( 200 , 202 , 204 , 206 , 208 , 210 , 212 ).

14. The wiper blade adapter system according to claim 1 , characterized in that the coupling unit ( 18 ) is configured to be detachably coupled to one of the at least two connecting elements ( 12 , 14 , 16 ).

15. The wiper blade adapter system according to claim 1 , characterized in that the ramp surface ( 24 ) abuts at least against a first guide element ( 92 , 94 ) of the elastically deflectable side wall ( 62 , 64 ) during the detachment process.

16. The wiper blade adapter system according to claim 1 , characterized in that the wiper blade adapter unit ( 10 ) has at least two longitudinal webs ( 46 , 48 ) which extend parallel to one another and are disposed on a base body ( 50 ) of the wiper blade adapter unit ( 10 ).

17. The wiper blade adapter system according claim 1 , characterized in that the wiper blade adapter unit ( 10 ) has an oblique locating surface ( 56 ) which is configured to delimit a deflection of a connecting element ( 12 , 14 , 16 ) of the at least two connecting elements ( 12 , 14 , 16 ) relative to a base body ( 50 ) of the wiper blade adapter unit ( 10 ).

18. A wiper blade ( 58 ) comprising the wiper blade adapter system according to claim 1 .

19. A method for detaching the wiper blade adapter system according to claim 1 , wherein one of the at least two connecting elements ( 12 , 14 , 16 ) is released from the wiper blade adapter unit ( 10 ) by the connecting element ( 12 , 14 , 16 ) being lifted on one side.

20. The wiper blade adapter system according to claim 1 , wherein the ramped surface is arcuately shaped.

21. The wiper blade adapter system according to claim 1 , wherein the coupling unit ( 18 ) and the connecting elements ( 12 , 14 , 16 ) are arranged such that during installation the elastically deflectable side wall deflects laterally inwardly after extending laterally outwardly.

22. The wiper blade adapter system according to claim 1 , wherein the transmission unit ( 20 ) and connecting elements ( 12 , 14 , 16 ) are arranged such that to remove one of the connecting elements from the wiper blade adapter unit ( 10 ), the connecting element is configured to be raised in a lifting region ( 80 ) at a first end of the connecting element, thereby forcing a second opposite end of the connecting element to pivot downwards and to engage the ramp surface ( 24 ) and deflect the elastically deflectable side wall ( 62 , 64 ) laterally outwardly.
