Abstract

The invention relates to an adapter unit which is provided for coupling, in particular releasably coupling, a wiper blade to a wiper arm, having a wind deflecting surface which is designed to deflect inflowing air and press the wiper blade against a vehicle windshield. According to the invention, the wind deflecting surface has at least one first sub-surface and a second sub-surface, wherein the first sub-surface has a different orientation than the second sub-surface and/or the first sub-surface has a different geometry than the second sub-surface.

First claim

What is claimed is:

1. A wiper assembly comprising an adapter unit and a wiper blade and a wiper arm, wherein the adapter unit is configured to connect the wiper blade to the wiper arm, wherein the wiper arm extends along a wiper arm direction that is parallel with a main longitudinal extent of the adapter unit, the adapter unit comprising a wind deflector face which is configured to deflect an incoming flow of air and to press the wiper blade against a vehicle window, characterized in that the wind deflector face has at least a planar first part-face and a planar second part-face, wherein the first part-face and the second part-face are separated by a separation line, wherein the separation line extends perpendicular to the wiper arm direction, wherein the first part-face has a different orientation from the second part-face, wherein the first part-face is arranged at a first angle between 5° and 30° relative to the second part-face, wherein the first angle is the angle between a surface normal of the first part-face and a surface normal of the second part-face.

2. The wiper assembly as claimed in claim 1 , characterized in that the wind deflector face encloses a main angle between 25° and 75° with a wind flow direction, wherein the main angle is an angle which the wind deflector face has with respect to the wind flow direction, and wherein the wind flow direction is perpendicular to the wiper arm direction.

3. The wiper assembly as claimed in claim 1 , characterized in that the first part-face and the second part-face coincide at least partially in the separation line and define a second angle at the separation line, wherein the second angle is located at an outer side of the wind deflector face or at a wind-facing side of the wind deflector face and the second angle is between 180° and 270°.

4. The wiper assembly as claimed in claim 3 , characterized in that the first part-face and the second part-face coincide at least partially in the separation line and define a third angle at the separation line, wherein the third angle is located at an outer side of the wind deflector face or at a wind-facing side of the wind deflector face and the third angle is between 90° and 180°.

5. The wiper assembly as claimed in claim 1 , characterized by a rear side which is arranged at a side of the adapter unit opposite the wind deflector face and which is arranged at a downwind side of the adapter unit, wherein the rear side is tilted by a rear angle between 10° and 40° relative to a surface normal of an adapter unit base face, so that the rear side projects beyond the adapter unit base face in the wind flow direction.

6. The wiper assembly as claimed in claim 1 , characterized by a wiper-arm-facing surface arranged at a side of the adapter which is configured to introduce and/or receive the wiper arm for connection to the adapter unit, wherein the wiper-arm-facing surface is tilted by a right-handed angle between 10° and 40° relative to a surface normal of an adapter unit base face.

7. The wiper assembly as claimed in claim 6 , characterized in that the wiper-arm-facing surface is constructed to be concave at least in regions.

8. The wiper assembly as claimed in claim 1 , characterized by a wiper-arm-remote surface which is arranged opposite a side of the adapter unit which is provided so that the wiper arm is connected to the adapter unit at that side, wherein the wiper-arm-remote surface is tilted by a left-handed angle between 10° and 40° relative to a surface normal of an adapter unit base face.

9. The wiper assembly as claimed in claim 8 , characterized in that the wiper-arm-remote surface is constructed to be convex at least in regions.

10. The wiper assembly as claimed in claim 1 , characterized in that the adapter unit is configured to connect the wiper arm to the wiper blade so as to be pivotable about a bearing axis.

11. The wiper assembly as claimed in claim 1 , comprising a base element, a covering element and a wiper arm receiving member which is provided to receive the wiper arm so as to be pivotable about a bearing axis, wherein the covering element is constructed so as to be connectable to the base element and substantially covers the wiper arm receiving member, and wherein the covering element has the wind deflector face, and wherein the base element is configured to receive the wiper blade.

12. The wiper assembly as claimed in claim 1 , characterized in that the adapter unit is configured to releasably connect the wiper blade to the wiper arm.

13. The wiper assembly as claimed in claim 1 , characterized in that the wind deflector face encloses a main angle between 40° and 60° with a wind flow direction, wherein the main angle is an angle which the wind deflector face has with respect to the wind flow direction, and wherein the wind flow direction is perpendicular to the wiper arm direction.

14. The wiper assembly as claimed in claim 1 , characterized in that the first angle is between 10° and 20°.

15. The wiper assembly as claimed in claim 1 , characterized in that the first part-face and the second part-face coincide at least partially in the separation line and define a second angle at the separation line, wherein the second angle is located at an outer side of the wind deflector face or at a wind-facing side of the wind deflector face and the second angle is between 190° and 235°.

16. The wiper assembly as claimed in claim 1 , characterized in that the first part-face and the second part-face coincide at least partially in the separation line and define a second angle at the separation line, wherein the second angle is located at an outer side of the wind deflector face or at a wind-facing side of the wind deflector face and the second angle is between 200° and 220°.

17. The wiper assembly as claimed in claim 1 , characterized in that the first part-face and the second part-face coincide at least partially in the separation line and define a third angle at the separation line, wherein the third angle is located at an outer side of the wind deflector face or at a wind-facing side of the wind deflector face and the third angle is between 135° and 170°.

18. The wiper assembly as claimed in claim 1 , characterized in that the first part-face and the second part-face coincide at least partially in the separation line and define a third angle at the separation line, wherein the third angle is located at an outer side of the wind deflector face or at a wind-facing side of the wind deflector face and the third angle is between 150° and 160°.

19. The wiper assembly as claimed in claim 1 , characterized by an upper face which is arranged at a downwind side of the wind deflector face and which is orientated parallel or substantially parallel with the wiper arm direction and wherein the upper face encloses an upper angle between 15° and 20° with the wind flow direction so that the upper face is configured to deflect an incoming flow of air and to press the wiper blade against a vehicle window.

20. The wiper assembly as claimed in claim 1 , characterized by a rear side which is arranged at a side of the adapter unit opposite the wind deflector face and which is arranged at a downwind side of the adapter unit, wherein the rear side is tilted by a rear angle between 20° and 30° relative to a surface normal of an adapter unit base face, so that the rear side projects beyond the adapter unit base face in the wind flow direction.
