Claim:
1. A wiper arm apparatus comprising a wiper stem ( 116 ) of a wiper arm, a windshield wiper fluid duct ( 122 ), and a wiper arm wind deflector unit, wherein the wiper arm wind deflector unit includes at least one wind deflector element ( 112 a , 112 b ; 212 a , 212 b ; 312 a , 312 b ) including at least one first coupling unit ( 114 a , 114 b ; 214 a , 214 b ; 314 a , 314 b ) which in a mounted state is configured to be connected to the wiper stem ( 116 ; 216 ; 316 ) of the wiper arm ( 118 ; 218 ; 318 ) and including at least one second coupling unit ( 120 a , 120 b ; 220 a , 220 b ; 320 a , 320 b ) which in a mounted state is configured to receive the windshield wiper fluid duct ( 122 ; 222 ; 322 ), wherein the wind deflector element ( 112 a , 112 b ) includes an opening ( 132 a , 132 b ) along an exterior of the wind deflector element ( 112 a , 112 b ) that opens into a single recessed cavity within the wind deflector element ( 112 , 112 b ), wherein the single recessed cavity defines both a first receiving region ( 128 a , 128 b ) in the first coupling unit ( 114 a , 114 b ) to hold the wiper stem ( 116 ) and a second receiving region ( 130 a , 130 b ) in the second coupling unit ( 120 a , 120 b ) to hold the wiper fluid duct ( 122 ), wherein the opening ( 132 a , 132 b ) opens directly into only the second receiving region ( 130 a , 130 b ), such that the second receiving region ( 130 a , 130 b ) is disposed between the opening ( 132 a , 132 b ) and the first receiving region ( 128 a , 128 b ), wherein the at least one first coupling unit ( 114 a , 114 b ; 214 a , 214 b ; 314 a , 314 b ) is coupled to the wiper stem ( 116 ; 216 ; 316 ) of the wiper arm ( 118 ; 218 ; 318 ) and the at least one second coupling unit ( 120 a , 120 b ; 220 a , 220 b ; 320 a , 320 b ) is coupled to the windshield wiper fluid duct ( 122 ; 222 ; 322 ), and wherein the wiper arm is configured to be coupled to a wiper blade.
