## 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).

## Claims

### Claim 1

A windscreen wiper for a motor vehicle window, comprising:
a longitudinally extending wiper blade;
an aerodynamic deflector extending longitudinally above said wiper blade;
at least one longitudinally extending fluid circulation duct having at least one spraying orifice; and
at least one lower lateral skirt extending longitudinally on a lateral side of the wiper blade and of the spraying orifice, the spraying orifice being located between the wiper blade and the lower lateral skirt.

### Claim 2 (depends on 1)

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.

### Claim 3 (depends on 1)

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

### Claim 4 (depends on 3)

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

### Claim 5 (depends on 1)

The windscreen wiper according to claim 1, wherein the spraying orifice has a spraying direction directed approximately parallel to the wiper blade.

### Claim 6 (depends on 1)

The windscreen wiper according to claim 1, wherein the spraying orifice has a spraying direction directed approximately towards the lower lateral skirt.

### Claim 7 (depends on 1)

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

### Claim 8 (depends on 1)

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.

### Claim 9

A method for manufacturing a windscreen wiper, comprising:
extruding a profiled element comprising at least one lower lateral skirt and at least one fluid circulation duct; and
piercing at least one spraying orifice into the at least one fluid circulation duct through the lower lateral skirt.

### Claim 10

A method for manufacturing a windscreen wiper, comprising:
extruding a profiled element comprising at least one lower lateral skirt and at least one fluid circulation duct;
opening up access to a lower part of the at least one fluid circulation duct;
piercing a spraying orifice into the at least one fluid circulation duct; and
barring the access to the lower part of the at least one fluid circulation duct again.

### Claim 11 (depends on 10)

The method for manufacturing a windscreen wiper according claim 10, wherein the access to a lower part of the at least one fluid circulation duct is opened up by lifting the at least one lower lateral skirt.
