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.
Claims28
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.
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 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°.
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 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°.
