Abstract

The invention is based on a wiper blade device having an adapter element ( 14 ) that can be fixedly connected to a main component ( 10 ) of a wiper blade ( 11; 12; 13 ), said adapter element ( 14 ) comprising at least two side walls ( 16, 18 ) facing one another, which at least partially delimit a receiving region ( 20 ) for at least one part of at least one holding element ( 21; 22; 23 ) for a wiper arm ( 24; 26; 28 ). The invention states that at least one of the side walls ( 16, 18 ) has at least one recess ( 34, 36 ), formed as a bearing opening ( 30, 32 ), for a bearing element ( 38; 40 ).

First claim

What is claimed is:

1. A wiper system comprising: a wiper blade device having an adapter element ( 14 ) which is configured to be securely connected to a main component ( 10 ) of a wiper blade ( 11 ; 12 ; 13 ); and
a wiper arm having a retention element, wherein the adapter element ( 14 ) comprises at least two mutually opposed side walls ( 16 , 18 ) which at least partially delimit a receiving region ( 20 ) for at least a portion of the wiper arm ( 24 : 26 : 28 ) or at least the retention element ( 21 ; 22 ; 23 ) for the wiper arm ( 24 ; 26 ; 28 ), characterized in that at least one of the side walls ( 16 , 18 ) has at least one recess ( 34 , 36 ) which is constructed as a bearing opening ( 30 , 32 ) for a bearing element ( 38 ; 40 ), the bearing element ( 38 , 40 ) defining an axis of rotation, wherein the adapter element ( 14 ) comprises at least one other side wall ( 42 ) which has a side face ( 44 ) which faces the receiving region ( 20 ), wherein the side face ( 44 ) has a concave curvature when viewed in a direction along the axis of rotation, and wherein the side face ( 44 ) is in physical abutment with the retention element ( 21 ; 22 ; and 23 ).

2. The wiper blade device as claimed in claim 1 , characterized in that the other side wall ( 42 ) connects the mutually opposed side walls ( 16 , 18 ).

3. The wiper blade device as claimed in claim 1 , characterized in that the side face ( 44 ) is arranged at least substantially perpendicularly relative to a main extent plane ( 46 ) of at least one of the mutually opposed side walls ( 16 , 18 ).

4. The wiper blade device as claimed in claim 1 , characterized in that the side face ( 44 ) at least partially is at least substantially in the form of a portion of a cylinder covering surface.

5. The wiper blade device as claimed in claim 1 further comprising the bearing element ( 38 ; 40 ).

6. The wiper blade device as claimed in claim 5 , characterized in that the bearing element ( 38 ; 40 ) is formed at least partially by a bearing pin ( 56 ; 58 ).

7. The wiper blade device as claimed in claim 5 , characterized in that the retention element ( 23 ) is constructed integrally with the bearing element ( 40 ).

8. The wiper blade device as claimed in claim 5 , characterized in that the bearing element ( 38 ) is constructed as a separate component ( 60 ).

9. The wiper blade device as claimed in claim 1 , further comprising the wiper arm ( 24 ; 26 ; 28 ), characterized in that the retention element ( 22 ; 23 ) is connected to the wiper arm ( 26 ; 28 ) in a non-releasable manner.

10. The wiper blade device as claimed in claim 1 , further comprising the wiper arm ( 24 ; 26 ; 28 ), characterized in that the retention element ( 21 ; 22 ) is connected to the wiper arm ( 24 ; 26 ) as a separate component ( 62 ; 64 ).

11. The wiper blade device as claimed in claim 1 , characterized in that the retention element ( 21 ; 22 ) has at least one recess ( 66 ; 68 , 69 ) for receiving the bearing element ( 38 ).

12. The wiper blade device as claimed in claim 1 , further comprising the wiper arm ( 24 ; 26 ; 28 ), characterized in that the retention element ( 21 ; 22 ; 23 ) rotatably secures the wiper arm ( 24 ; 26 ; 28 ) to the adapter element ( 14 ), at least in a positive-locking manner.

13. The wiper blade device as claimed in claim 1 , characterized in that the retention element ( 22 ) has a catch element ( 70 ) for connection to the wiper arm ( 26 ).

14. The wiper blade device as claimed in claim 1 , characterized in that the retention element ( 21 ) has at least one outer face ( 72 ), which is at least partially adapted to a surface ( 74 ) of the wiper arm ( 24 ).

15. The wiper blade device as claimed in claim 14 , characterized in that the outer face ( 72 ) has at least one main curvature in at least one direction ( 48 ).

16. The wiper blade device as claimed in claim 1 , further comprising the wiper arm ( 24 ), characterized in that the wiper arm ( 24 ) in the at least one assembled state is retained between the retention element ( 21 ) and the adapter element ( 14 ) at least in a positive-locking manner.

17. The wiper blade device as claimed in claim 1 , characterized in that the receiving region ( 20 ) is formed so as to be at least partially open at a side facing away from the main component ( 10 ).

18. The wiper blade device as claimed in claim 1 , characterized in that the receiving region ( 20 ) is formed so as to be at least partially open at a side opposite the other side wall ( 42 ).

19. The wiper blade device as claimed in claim 1 , characterized in that the adapter element ( 14 ) has at least one fixing unit ( 76 ) configured for a direct and secure connection with respect to a resilient strip ( 78 ) of the wiper blade ( 11 ; 12 ; 13 ).

20. The wiper blade device as claimed in claim 1 , wherein the at least one other side wall ( 42 ) extends entirely between the mutually opposed side walls ( 16 , 18 ).

21. The wiper blade device as claimed in claim 1 , wherein the receiving region ( 20 ) includes a front end and an opposite rear end, wherein the rear end is defined by the at least one other side wall ( 42 ), and wherein the bearing opening ( 30 , 32 ) is disposed closer to the rear end than the front end.

22. A wiper system comprising: a wiper blade device having an adapter element ( 14 ) which is configured to be securely connected to a main component ( 10 ) of a wiper blade ( 11 ; 12 ; 13 ); and
a wiper arm,
wherein the adapter element ( 14 ) comprises at least two mutually opposed side walls ( 16 , 18 ) which at least partially delimit a receiving region ( 20 ) for at least a portion of the wiper arm ( 24 : 26 : 28 ) or at least the retention element ( 21 ; 22 ; 23 ) for the wiper arm ( 24 ; 26 ; 28 ), characterized in that at least one of the side walls ( 16 , 18 ) has at least one recess ( 34 , 36 ) which is constructed as a bearing opening ( 30 , 32 ) for a bearing element ( 38 ; 40 ), the bearing element ( 38 , 40 ) defining an axis of rotation, wherein the adapter element ( 14 ) comprises at least one other side wall ( 42 ) which has a side face ( 44 ) which faces the receiving region ( 20 ), wherein the side face ( 44 ) has a concave curvature when viewed in a direction along the axis of rotation, and wherein the side face ( 44 ) is in physical abutment with the wiper arm.
