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 pane, wherein the wind deflecting surface is bordered by a wind deflecting surface edge, and the wind deflecting surface edge has at least •a side which faces the wind and which extends largely in a wiper arm direction, •a side which faces away from the wind and which extends largely in the wiper arm direction, a right-hand side which is arranged between the side facing the wind and the side facing away from the wind and which is arranged on the wiper arm side of the adapter and is designed to couple the adapter unit to the wiper arm, •a rear left-hand side which adjoins the side facing away from the wind and is arranged on the adapter side opposite the wiper arm side, and •a front left-hand side which adjoins the side facing the wind and is arranged on the adapter side lying opposite the wiper arm side. According to the invention, the side facing away from the wind and the right-hand side define a rear angle ranging between 110° and 160°, preferably between 120° and 150°, particularly preferably between 130° and 140°.

First claim

What is claimed is:

1. An adapter unit which is configured to couple a wiper blade to a wiper arm, the adapter unit having a wind deflector face which is configured for deflecting an incident flow of air and for pressing the wiper blade onto a vehicle glass, wherein the wind deflector face is bordered by a wind deflector face periphery, and the wind deflector face periphery has at least
a side configured to face a wind, the side configured to face the wind extending largely in a wiper arm direction,
a side configured to face away from the wind, the side configured to face away from the wind extending largely in the wiper arm direction,
a right side which is disposed between the side configured to face the wind and the side configured to face away from the wind and is disposed on a wiper arm side of the adapter on which the adapter unit is configured to be coupled to the wiper arm,
a rear left side which is adjacent to the side configured to face away from the wind and is disposed on a side of the adapter that is opposite the wiper arm side of the adapter, and
a front left side which is adjacent to the side configured to face the wind and is disposed on the side of the adapter that is opposite the wiper arm side of the adapter, characterized in that the side configured to face away from the wind and the right side define a rear angle between 110° and 160°, wherein the wind deflector face has a button which is configured for releasably coupling the wiper arm to the adapter unit, wherein the button is configured as a latching button which is disposed in a button opening, wherein the latching button is configured such that the latching button is disposed so as to be centric or largely centric in the button opening when the wiper arm is latched, and in that the latching button bears on an upper edge of the button opening when the wiper arm is not latched.

2. The adapter unit as claimed in claim 1 , characterized in that the rear left side and the front left side define a left-hand angle between 70° and 120°.

3. The adapter unit as claimed in claim 1 , characterized in that the side configured to face the wind in relation to the side configured to face away from the wind is disposed at a front right-hand angle between 0.0° and 20.0°.

4. The adapter unit as claimed in claim 1 , characterized in that the front left side in relation to the side configured to face away from the wind is disposed at a front left-hand angle between 10° and 60°.

5. The adapter unit as claimed in claim 1 , characterized in that the front left side in relation to the right side is disposed at an internal angle between 0° and 50°, the side configured to face the wind extending between 10° and 40°.

6. The adapter unit as claimed in claim 1 , characterized in that the wind deflector face has a rectangular push button which is configured for releasably coupling the wiper arm to the adapter unit, wherein two opposite lateral edges of a button contour of the button are oriented so as to be parallel or largely parallel to the right side.

7. The adapter unit as claimed in claim 1 , characterized in that the wind deflector face has a button which is configured for releasably coupling the wiper arm to the adapter unit, wherein the button is configured as a spring button having a spring for applying a restoring force, wherein the spring has an arcuate piece having at least one rib, wherein the at least one rib is oriented so as to be parallel or largely parallel to a radius of the arcuate piece and is provided for reinforcing the arcuate piece.

8. The adapter unit as claimed in claim 1 , characterized in that the adapter unit is configured for connecting the wiper arm to the wiper blade so as to be pivotable about a mounting axis.

9. The adapter unit as claimed in claim 8 , comprising a wiper arm adapter unit and a wiper blade adapter unit, wherein the wiper arm adapter unit is configured for coupling to the wiper arm, and the wiper blade adapter unit is configured for receiving the wiper blade, wherein the wiper arm adapter unit has a wiper blade adapter unit receptacle which is configured for receiving the wiper blade adapter unit so as to be pivotable about the mounting axis.

10. The adapter unit as claimed in claim 9 , characterized in that wiper arm adapter unit includes the wind deflector face.

11. The adapter unit as claimed in claim 8 , comprising a base element, a cover element, and a wiper arm receptacle which is configured for receiving the wiper arm so as to be pivotable about the mounting axis, wherein the cover element is configured so as to be connectable to the base element and largely covers the wiper arm receptacle, and wherein the cover element has the wind deflector face, and wherein the base element is configured for receiving the wiper blade.

12. The adapter unit as claimed in claim 11 , wherein the cover element is configured so as to be fixedly connectable to the base element such that the cover element connected to the base element is largely immovable in relation to the base element.

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

14. The adapter unit as claimed in claim 1 , characterized in that the side configured to face away from the wind and the right side define a rear angle between 120° and 150°.

15. The adapter unit as claimed in claim 1 , characterized in that the side configured to face away from the wind and the right side define a rear angle between 130° and 140°.

16. The adapter unit as claimed in claim 1 , characterized in that the rear left side and the front left side define a left-hand angle between 80° and 110°.

17. The adapter unit as claimed in claim 1 , characterized in that the rear left side and the front left side define a left-hand angle between 90° and 100°.

18. The adapter unit as claimed in claim 1 , characterized in that the side configured to face the wind in relation to the side configured to face away from the wind is disposed at a front right-hand angle between 2.5° and 15.0°.
