Abstract:
1. A wiper device comprising a wiper arm ( 10 a ; 10 b ) having a connection end and an intermediate portion supporting an inner circle guide unit ( 14 a; 14 b ) spaced from the connection end and having an inner circle guide element ( 16 a ; 16 b ) for guiding a wiper blade ( 12 a ; 12 b ), the wiper blade ( 12 a ; 12 b ) having a first end and a second end spaced from the first end along a longitudinal axis of the wiper blade ( 12 a ; 12 b ), characterized in that the wiper blade ( 12 a ; 12 b ) is connected to the connection end of the wiper arm ( 10 a ; 10 b ) at a connection point between the first end and the second end and to the intermediate portion of the wiper arm ( 10 a ; 10 b ), via the inner circle guide unit ( 14 a ; 14 b ), proximate the second end, characterized in that the inner circle guide unit ( 14 a ; 14 b ) is configured to guide the second end of the wiper blade ( 12 a ; 12 b ) along an inner circular trajectory ( 24 a ) of the wiper arm ( 10 a ; 10 b ), wherein the inner circle guide unit ( 14 a ; 14 b ) has at least one nozzle element ( 18 a ; 18 b ) for spraying washing liquid onto a motor vehicle windshield ( 20 a ), and characterized in that the at least one nozzle element ( 18 a ) has a spraying direction ( 28 a ) which extends substantially radially to the inner circular trajectory ( 24 a ) of the wiper arm ( 10 a ; 10 b ), the arm ( 10 a ; 10 b ) being pivotally mounted for rotation about an axis, wherein the inner circle guide unit ( 14 a ; 14 b ) has at least one latching means ( 30 a , 32 a ; 30 b , 32 b ) for forming a latching connection with the wiper arm ( 10 a ; 10 b ) and a guide recess ( 40 a ; 40 b ) for receiving the wiper blade ( 12 a ; 12 b ) in an interlocking manner, wherein the wiper arm ( 10 a; 10 b ), the wiper blade ( 12 a ; 12 b ), the at least one latching means ( 30 a , 32 a ; 30 b , 32 b ), and the guide recess ( 40 a ; 40 b ) are centered over the longitudinal axis, and wherein the at least one nozzle element ( 18 a ; 18 b ) is below the at least one latching means ( 30 a , 32 a ; 30 b , 32 b ) relative to the motor vehicle windshield.
