Abstract

The invention relates to a wiper blade adapter unit with a wiper blade adapter (10), which is provided for a connection to a wiper arm adapter and has at least one receiving area (12, 14) having at least one contact surface (16, 18) provided for fastening at least one carrier element (20, 22) of a wiper blade. The invention states that the at least one contact surface (16, 18) has a maximum length of 20 mm.

First claim

What is claimed is:

1. A wiper blade adapter unit with a wiper blade adapter ( 10 ), which is configured to be connected to a wiper arm adapter and which has at least one receiving area ( 12 , 14 ) having at least one contact surface ( 16 , 18 ) configured for fastening at least one carrier element ( 20 , 22 ) of a wiper blade, characterized in that the at least one contact surface ( 16 , 18 ) has a maximum length of 20 mm.

2. The wiper blade adapter unit according to claim 1 , characterized in that the at least one contact surface ( 16 , 18 ) has a maximum length of 15 mm.

3. The wiper blade adapter unit according to claim 1 , characterized in that the at least one contact surface ( 16 , 18 ) has a maximum length of 7 mm.

4. The wiper blade adapter unit according to claim 1 , characterized in that the at least one receiving area ( 12 , 14 ) comprises a plateau ( 24 , 26 ) forming the at least one contact surface ( 16 , 18 ).

5. The wiper blade adapter unit according to claim 4 , further comprising at least one energy directing element ( 40 , 42 ) which is disposed on the contact surface ( 16 , 18 ).

6. The wiper blade adapter unit according to claim 1 , characterized in that the at least one receiving area ( 12 , 14 ) has a base ( 28 , 30 ) which differs in a height thereof by at least 0.5 mm from a height of the at least one contact surface ( 16 , 18 ).

7. The wiper blade adapter unit according to claim 6 , characterized in that the base ( 28 , 30 ) of the at least one receiving area ( 12 , 14 ) is spaced apart from a bottom side ( 32 , 34 ) of the wiper blade adapter ( 10 ) at a distance which is less than a distance between the at least one contact surface ( 16 , 18 ) and the bottom side ( 32 , 34 ).

8. The wiper blade adapter unit at least according to claim 6 , characterized in that the base ( 28 , 30 ) of the at least one receiving area ( 12 , 14 ) is connected via an oblique surface ( 36 , 38 ) to the at least one contact surface ( 16 , 18 ).

9. The wiper blade adapter unit according to claim 1 , characterized in that the length of the at least one contact surface ( 16 , 18 ) is at least substantially a quarter of a length of the at least one receiving area ( 12 , 14 ).

10. The wiper blade adapter unit according to claim 1 , characterized in that the at least one contact surface ( 16 , 18 ) has a width that corresponds at least substantially to a width of the at least one receiving area ( 12 , 14 ).

11. The wiper blade adapter unit according to claim 1 , characterized by at least one energy directing element ( 40 , 42 ) which is disposed on the contact surface ( 16 , 18 ).

12. The wiper blade adapter unit according to claim 11 , characterized in that the at least one energy directing element ( 40 , 42 ) is configured to be at least partially fused to the at least one carrier element ( 20 , 22 ) during a welding process.

13. The wiper blade adapter unit according to claim 1 , characterized in that the wiper blade adapter ( 10 ) comprises at least one blind hole ( 44 , 46 ) which is disposed above the at least one contact surface ( 16 , 18 ).

14. The wiper blade adapter unit according to claim 13 , characterized in that the at least one blind hole ( 44 , 46 ) is designed as an elongated hole.

15. The wiper blade adapter unit at least according to claim 13 , characterized in that a base delimiting the at least one blind hole ( 44 , 46 ) is configured to be fused to the at least one carrier element ( 20 , 22 ) during a welding process.

16. The wiper blade adapter unit according to claim 1 , characterized by at least one second receiving area ( 12 , 14 ) which likewise has at least one contact surface ( 16 , 18 ) which is provided for mounting at least one further carrier element ( 20 , 22 ).

17. A wiper blade device comprising a wiper blade adapter unit according to claim 1 and at least one carrier element ( 20 , 22 ) fastened to the adapter unit.

18. The wiper blade device according to claim 17 , characterized in that the wiper blade adapter unit and the at least one carrier element ( 20 , 22 ) are fixedly connected to one another by means of a materially bonded connection.

19. The wiper blade device according to claim 18 , characterized in that the wiper blade adapter unit and the at least one carrier element ( 20 , 22 ) are fixedly connected to one another by means of a welded connection.

20. The wiper blade device according to claim 19 , characterized in that the at least one carrier element ( 20 , 22 ) is joined to the at least one contact surface ( 16 , 18 ) of the wiper blade adapter unit by means of an ultrasonic welding process.

21. A wiper blade comprising a wiper blade device according to claim 17 .
