Abstract

The invention is based on a wiper connecting unit with a basic body ( 12 ) for connecting a wiper blade adapter ( 14 ) to a wiper arm ( 16 ) of a wiper. It is proposed that the basic body ( 12 ) has a spoiler receiving region ( 20 ) arranged on one side ( 18 ) of the wiper arm.

First claim

What is claimed is:

1. A wiper connecting unit with a basic body ( 12 ) configured to connect a wiper blade adapter ( 14 ) to a wiper arm ( 16 ) of a wiper, characterized in that the basic body ( 12 ) extends along a longitudinal direction ( 22 ) and has a top side ( 26 ) configured to face away from the wiper blade adapter ( 14 ) when the basic body ( 12 ) is connected to the wiper blade adapter ( 14 ), a bottom side ( 30 ) disposed opposite and facing away from the top side ( 26 ), a first end ( 18 ) that has a spoiler receiving region ( 20 ) to receive a portion of a spoiler element ( 60 ) along the longitudinal direction ( 22 ), a second, opposite end ( 90 ) spaced from the first end ( 18 ) along the longitudinal direction ( 22 ), a first side wall ( 32 ) disposed between the first and second ends ( 18 , 90 ) and between the top side ( 26 ) and bottom side ( 30 ), and a second side wall disposed between the first and second ends and between the top side ( 26 ) and the bottom side ( 30 ), the second side wall disposed opposite the first side wall ( 32 ), wherein the basic body ( 12 ) further includes a fluid-retaining element ( 52 ) along the first end ( 18 ) that includes a wall that is angled relative to the longitudinal direction ( 22 ) at an oblique angle, wherein the wall of the fluid retaining element ( 52 ) extends at least substantially an entire distance between the first side wall ( 32 ) and the second side wall, and wherein the spoiler receiving region ( 20 ) includes an opening on the wall of the fluid retaining element ( 52 ).

2. The wiper connecting unit according to claim 1 , characterized in that the fluid-retaining element ( 52 ) is a first fluid-retaining element, and wherein the basic body ( 12 ) has a second fluid-retaining element ( 24 ) which is at least partially adjacent to the spoiler receiving region ( 20 ) transversely with respect to the longitudinal direction ( 22 ) of the basic body ( 12 ), wherein the wall of the first fluid retaining element ( 52 ) extends from the first side wall ( 32 ) to the second fluid-retaining element ( 24 ).

3. The wiper connecting unit according to claim 2 , characterized in that the second fluid-retaining element ( 24 ) is of curved design starting from the spoiler receiving region ( 20 ), as viewed from the top side ( 26 ) of the basic body ( 12 ) looking toward the bottom side ( 30 ).

4. The wiper connecting unit at least according to claim 2 , characterized in that the basic body ( 12 ) has a third fluid-retaining element ( 28 ) which adjoins the second fluid-retaining element ( 24 ), is arranged on the bottom side ( 30 ) and extends with at least one component, which extends perpendicularly to the first side wall ( 32 ), into an inner region ( 34 ) of the basic body ( 12 ).

5. The wiper connecting unit according to claim 4 , characterized in that the second fluid-retaining element ( 24 ) is at least partially formed integrally with the third fluid-retaining element ( 28 ).

6. The wiper connecting unit according to claim 1 , characterized in that the basic body ( 12 ) has a bearing receptacle ( 36 ) which is configured to receive a bearing element ( 38 ) for pivotable mounting of the basic body ( 12 ) relative to the wiper blade adapter ( 14 ).

7. A wiper blade with at least one spoiler unit ( 42 ), with a wiper blade adapter ( 14 ) which is at least partially arranged in a recess ( 44 ) of the spoiler unit ( 42 ), and with the wiper connecting unit ( 10 ) of claim 1 , characterized in that the wiper connecting unit ( 10 ) overlaps a side ( 48 ) of the spoiler unit ( 42 ) that faces away from a wiper blade main approach flow side ( 46 ), as viewed in an operating state, at least on the first end ( 18 ) of the basic body ( 12 ).

8. The wiper blade according to claim 7 , characterized in that the fluid-retaining element ( 52 ) is a first fluid-retaining element, and that a second fluid-retaining element ( 24 ) and a third fluid-retaining element ( 28 ) of the basic body ( 12 ) of the wiper connecting unit ( 10 ) at least partially overlap the spoiler unit ( 42 ) on the first side ( 18 ).

9. The wiper blade according to claim 7 , characterized in that the fluid-retaining element ( 52 ) is a first fluid-retaining element, and that a second fluid-retaining element ( 24 ) and a third fluid-retaining element ( 28 ) of the basic body ( 12 ) of the wiper connecting unit ( 10 ) bear in an at least partially sealing manner against a side ( 50 ) of the spoiler unit ( 42 ) which faces away from the wiper blade main approach flow side ( 46 ).

10. The wiper blade according to claim 1 , wherein the wall of the fluid retaining element ( 52 ) is angled relative to the longitudinal direction ( 22 ) at an angle of approximately 135 degrees.

11. The wiper blade according to claim 1 , wherein the wall of the fluid retaining element ( 52 ) extends greater than half of the distance between the first side wall ( 32 ) and the second side wall.

12. The wiper blade according to claim 11 , wherein the distance between the first side wall ( 32 ) and the second side wall is taken along a direction that is perpendicular to both the first side wall ( 32 ) and the second side wall.

13. The wiper blade according to claim 1 , wherein the wall of the fluid retaining element ( 52 ) is planar.

14. The wiper blade according to claim 1 , wherein the wall of the fluid retaining element ( 52 ) extends vertically along a direction perpendicular to the longitudinal direction ( 22 ).

15. The wiper blade according to claim 1 , wherein the first side wall ( 32 ) extends a shorter distance along the longitudinal direction ( 22 ) than the second side wall.
