Wiper device

1. A wiper device comprising a wiper blade adapter unit ( 10 a - 10 i ) which is configured to releasably couple a wiper blade ( 12 a - 12 i ) to a wiper arm adapter unit ( 14 a - 14 i ) and which includes at least one wiper blade adapter base member ( 16 a - 16 i ) configured to be fixedly connected to the wiper blade ( 12 a - 12 i ), and an adapter wind deflector unit ( 18 a - 18 i ) configured to deflect incident air and to press the wiper blade ( 12 a - 12 i ) against a vehicle windscreen ( 20 a ), wherein the wiper blade adapter base member ( 16 a - 16 i ) includes a wiper arm receiver ( 36 a - 36 i ) in the form of a pin ( 92 a ) that extends in an elongate direction that is parallel to a wiping direction and that which, when viewed along a longitudinal direction ( 30 a - 30 i ) of the wiper blade adapter unit ( 10 a - 10 i ), is arranged offset from a plane that both passes through a wiper blade adapter unit center of gravity ( 40 a - 40 i ) and is perpendicular to the elongate direction of the pin, wherein the longitudinal direction is a direction that extends parallel to a main longitudinal dimension of the wiper blade ( 12 a - 12 i ) and perpendicular to the elongate direction of the pin, wherein the wiper blade adapter base member includes two side walls ( 56 a , 58 a ), wherein the pin ( 92 ) extends between the two side walls, and wherein the wind deflector unit ( 18 a ) contacts an upper end of each the side walls, wherein the wiper blade base member ( 16 a - 16 i ) includes a base region ( 88 a ), wherein the first side wall ( 56 a ) extends a first distance from the base region ( 88 a ) along a vertical direction that is perpendicular to both the longitudinal direction ( 30 a ) and the elongate direction of the pin ( 92 a ), and the second side wall ( 58 a ) extends a second distance from the base region ( 88 a ) along the vertical direction, wherein the first distance is greater than the second distance.

2. The wiper device according to claim 1 , characterized in that the adapter wind deflector unit ( 18 a - 18 i ) is releasably fastened to the wiper blade adapter base member ( 16 a - 16 i ).

3. The wiper device according to claim 1 , characterized in that the adapter wind deflector unit ( 18 a - 18 i ) comprises at least one adapter cover element ( 22 a - 22 i ) which is configured to cover the wiper blade adapter base member ( 16 a - 16 i ) at least to a large extent.

4. The wiper device according to claim 1 , characterized in that the adapter wind deflector unit ( 18 a - 18 i ) comprises at least one first wind deflection surface ( 24 a - 24 i ) and an upper face ( 28 a - 28 i ) which enclose an angle of at least 110°.

5. The wiper device according to claim 1 , characterized in that the wiper arm receiver ( 36 a - 36 i ) is arranged offset from the wiper blade adapter center of gravity ( 40 a - 40 i ) in the direction of a leeward side ( 42 a - 42 i ) of the adapter wind deflector unit ( 18 a - 18 i ), wherein the leeward side is a side configured to be remote from a driving wind.

6. The wiper device according to claim 1 , wherein the first side wall ( 56 a ) and a second side wall ( 58 a ) are arranged parallel to one another.

7. The wiper device according to claim 6 , wherein the base region ( 88 a ) includes two claw-shaped spring rail retaining elements ( 52 a , 54 a ) defining a longitudinal guide channel configured to receive a spring rail, wherein the first side wall ( 56 a ) and the second side wall ( 58 a ) each extend along the vertical direction and away from the longitudinal guide channel.

8. The wiper device according to claim 6 , wherein the pin ( 92 a ) extends between the first side wall ( 56 a ) and the second side wall ( 58 a ) and is received in openings in the first side wall ( 56 a ) and the second side wall ( 58 a ).
