## Abstract

A motor vehicle screen wiper is of the type comprising a screen wiper blade having an articulated structure which carries, by means of a set of gripping elements, a wiping strip of flexible material. It also includes a flexible aerodynamic deflector mounted on the blade. The deflector includes at least one fastening lug which is fitted on to a gripping element of the articulated structure of the blade.

## Claims

### Claim 1

A screen wiper for wiping a contoured swept surface of a motor vehicle, the screen wiper comprising an elongated, articulated structure, said structure defining a longitudinal direction, the structure being deformable by relative movement of at least two components in a direction perpendicular relative to the elongation thereof, a swingle bar having at least two terminal ends and being part of said structure, a set of grippers coupled to a respective one of each of the swingle bar terminal ends; an elongated wiping strip of flexible material received within and engaged by said grippers and defining, with said structure, a plane, the structure urging the swingle bar and thus the wiping strip against the swept surface to enable the wiping strip to selectively deform in a direction perpendicular to the longitudinal direction; a flexible aerodynamic deflector; and fastening means mounting the deflector on the swingle bar, wherein said deflector is laterally spaced from said plane, and wherein the deflector includes at least one fastening lug with a slot therein elastically and directly engaging a corresponding one of the grippers to establish the fastening means.

### Claim 2 (depends on 1)

A screen wiper according to claim 1, wherein the at least one fastening lug is clipped elastically on to the corresponding gripper, the fastening lug and gripper immobilizing the lug against straight line movement with respect to the gripper.

### Claim 3 (depends on 1)

A screen wiper according to claim 1, wherein the at least one fastening lug is integral with the deflector.

### Claim 4 (depends on 1)

A screen wiper according to claim 1, wherein the at least one fastening lug is of a rigid plastics material, the flexible deflector being molded on to the lug.

### Claim 5 (depends on 1)

A screen wiper according to claim 1, in which the deflector has a plurality of fastening lugs, each attached to a respective gripper.

### Claim 6 (depends on 5)

A screen wiper according to claim 5, wherein the fastening lugs are equal in number to the grippers.

### Claim 7

A screen wiper for wiping a contoured swept surface of a motor vehicle the screen wiper comprising a structure with opposed terminal ends, the structure being deformable in longitudinal direction relative to the wiper blade and at right angles to the structure, the structure including a set of grippers coupled to each of the structure terminal ends; a wiping strip of flexible material secured within said grippers, the structure urging the wiping strip against the swept surface to enable the wiping strip to selectively deform in a direction perpendicular to the longitudinal direction; a flexible aerodynamic deflector; and fastening means mounting the deflector on the structure wherein the deflector includes at least one fastening lug attached on a corresponding one of the grippers to establish the fastening means wherein each gripper has a first portion, the wiping strip having a wiping strip head defining a face thereof, the first portion of the gripper being in engagement against the face of the wiping strip head, the gripper further having a flange portion parallel to its first portion, and a central foot joining the flange portion to the first portion, to define a spacing between the flange portion and the first portion, the at least one fastening lug having a fastening flange with a thickness substantially equal to the spacing, the fastening flange having a transverse edge defining a slot, and being formed with central opening with a further opening in the edge through the slot, the slot being of reduced width with respect to the central opening, the fastening flange being received longitudinally between the first portion and the flange portion of the gripper, with the central foot of the gripper being received through the slot and within the opening of the fastening flange, whereby the fastening lug is immobilized on the gripper.

### Claim 8 (depends on 7)

A screen wiper according to claim 7, wherein the deflector has a lateral surface facing towards the wiping strip, the at least one fastening lug further including a connecting portion joining the deflector lateral surface to the fastening flange of the lug.
