Abstract

The present invention relates to a windscreen wiper ( 1 ) for a motor vehicle window ( 3 ), comprising:
a longitudinally extending wiper blade ( 5 ), an aerodynamic deflector ( 9 ) extending longitudinally above said wiper blade ( 5 ), at least one longitudinally extending fluid circulation duct ( 31, 32 ) having at least one spraying orifice ( 35 ), characterized in that the wiper comprises at least one lower lateral skirt ( 43, 44 ) extending longitudinally on a lateral side of the wiper blade ( 5 ) and of the spraying orifice ( 35 ), the spraying orifice ( 35 ) being located between the wiper blade ( 5 ) and the lower lateral skirt ( 43, 44 ).

First claim

The invention claimed is:

1. A windscreen wiper for a motor vehicle window, comprising:
a longitudinally extending wiper blade;
an aerodynamic deflector that deflects air streams from the windscreen wiper,
wherein the aerodynamic deflector extends longitudinally above a head of said wiper blade,
wherein the aerodynamic deflector comprises at least one lower lateral skirt, and
wherein the aerodynamic deflector and the at least one lower lateral skirt are monolithic;
at least one longitudinally extending fluid circulation duct having at least one spraying orifice; and
wherein the at least one lower lateral skirt extends longitudinally on a lateral side of the wiper blade and of the spraying orifice, the spraying orifice is located between the wiper blade and the at least one lower lateral skirt,
wherein the spraying orifice has a spraying direction directed at the at least one lower lateral skirt, and
wherein the head of the wiper blade extends into a recess of a mount, the mount is located between the aerodynamic deflector and the wiper blade, and the aerodynamic deflector is mounted on the mount.

2. The windscreen wiper according to claim 1 , wherein said at least one fluid circulation duct is located in a lateral part of the aerodynamic deflector.

3. The windscreen wiper according to claim 1 , wherein the at least one lower lateral skirt is inclined with respect to the wiper blade.

4. The windscreen wiper according to claim 3 , wherein the at least one lower lateral skirt is inclined at an inclination angle of between 0° and 60°.

5. The windscreen wiper according to claim 1 , wherein the at least one spraying orifice has the spraying direction directed approximately parallel to the wiper blade.

6. The windscreen wiper according to claim 1 , wherein the at least one lower lateral skirt has at least one relief for projecting a jet of windscreen washer liquid in the spraying direction.

7. The windscreen wiper according to claim 1 , wherein the aerodynamic deflector comprises an upstream face and a downstream face, and wherein said upstream face and downstream face are in the form of circular arcs.

8. The windscreen wiper according to claim 1 , wherein the aerodynamic deflector comprises lateral protrusions that extend into lateral recesses of the mount located between the aerodynamic deflector and the wiper blade.
