Abstract

The invention proposes a wind deflector unit, more particularly a wiper arm wind deflector unit, having at least one wind deflector element ( 112 a, 112 b; 212 a, 212 b; 312 a, 312 b ), having at least one first coupling unit ( 114 a, 114 b; 214 a, 214 b; 314 a, 314 b ) which in an installed condition is designed to be connected to a wiper stem ( 116; 216; 316 ) of a wiper arm ( 118; 218; 318 ), and having at least one second coupling unit ( 120 a, 120 b; 220 a, 220 b; 320 a, 320 b ) which in an installed condition is designed to receive a wiper fluid duct ( 122; 222; 322 ).

First claim

What is claimed is:

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.

2. The wiper arm apparatus of claim 1 , characterized in that the at least one wind deflector element ( 112 a , 112 b ; 212 a , 212 b ; 312 a , 312 b ) is integrally configured with the at least one first coupling unit ( 114 a , 114 b ; 214 a , 214 b ; 314 a , 314 b ) and/or with the at least one second coupling unit ( 120 a , 120 b ; 220 a , 220 b ; 320 a , 320 b ).

3. The wiper arm apparatus of claim 1 , characterized in that the at least one first coupling unit ( 114 a , 114 b ; 214 a , 214 b ) and the at least one second coupling unit ( 120 a , 120 b ; 220 a , 220 b ) comprise at least one clip fastening element ( 124 a , 126 a , 124 b , 126 b ; 224 a , 226 a , 224 b , 226 b ).

4. The wiper arm apparatus of claim 1 , characterized in that the at least one first coupling unit ( 314 a , 314 b ) or the at least one second coupling unit ( 320 a , 320 b ) comprises at least one clip fastening element ( 326 a , 326 b ).

5. A method for producing a wiper arm apparatus as claimed in claim 1 , characterized in that the wind deflector unit ( 110 a , 110 b ; 210 a , 210 b ; 310 a , 310 b ) is at least partially produced in an extrusion process.

6. The wiper arm apparatus of claim 1 , wherein the wiper stem ( 116 ; 216 ; 316 ) is generally rectangular in cross-section and includes a lower, flat surface that extends from a first side to a second, opposite side of the wiper stem ( 116 ; 216 ; 316 ), wherein the windshield wiper fluid duct ( 122 ; 222 ; 322 ) is generally circular in cross-section, wherein a radius of the circular cross-section of the wiper stem ( 116 ; 216 ; 316 ) extends perpendicular to the lower, flat surface at a central location on the lower, flat surface between the first and second ends, and wherein the first receiving region ( 128 a , 128 b ) has a generally rectangular shape and the second receiving region ( 130 a , 130 b ) has a generally circular shape.

7. The wiper arm apparatus of claim 1 , wherein the first receiving region ( 128 a , 128 b ) has a generally rectangular shape and the second receiving region ( 130 a , 130 b ) has a generally circular shape.

8. The wiper arm apparatus of claim 1 , wherein a main extension plane ( 170 ) extends through the first receiving region ( 128 a , 128 b ) but not the second receiving region ( 130 a , 130 b ), wherein the first receiving region ( 128 a , 128 b ) is disposed directly above the second receiving region ( 130 a , 130 b ) along an axis that is perpendicular to the main extension plane ( 170 ), and wherein the axis extends through the opening ( 132 a , 132 b ), the second receiving region ( 130 a , 130 b ), and the first receiving region ( 128 a , 128 b ).
