Abstract

The invention proposes a windshield wiper arm of the kind comprising a wiping strip (12) for the glass and a structure acting as a wiping strip support, which is connected to the free end of a driving arm and which comprises a profiled member (10) in a single piece, to which the driving arm is coupled and which receives the wiping strip (12) directly.

Claims

1. A windshield wiper blade comprising:

a wiper strip including a hollow coupling portion, said coupling portion having a pair of spaced apart wall members, each of said wall members having an inside surface, each inside surface including a plurality of grooves, said wiper strip further including a wiper member extending from said coupling portion for engaging a surface to be wiped;

a support member releasably locked in the space between said coupling portion wall members, said support member having a pair of spaced apart side walls and a support wall extending between said side walls, each of said side walls engaging one of the wall members of the coupling portion and having an outside surface and an inside surface, each outside surface of each said side wall having a plurality of ribs, each of said ribs being received in one of the grooves of its associated coupling portion wall member, and

an intermediate portion having a bellows defining folds extending longitudinally, with the bellows joining the wiping element to the hollow coupling portion.

2. A windshield wiper blade according to claim 1, wherein the hollow coupling portion has a substantially U-shaped transverse cross section, the side walls of the support member being substantially enclosed by the wall members of the coupling portion of the wiping strip.

3. A windshield wiper blade according to claim 2, wherein the support member has a substantially U-shaped transverse cross section, which cooperates with the wiping strip to define an internal chamber of substantially rectangular cross section.

4. A windshield wiper blade according to claim 3, which further includes a resiliently deformable material in the internal chamber, the latter deformable material in the internal chamber, the latter being filled with said material.

5. A windshield wiper blade according to claim 4, wherein the resiliently deformable material is a foam.

6. A windshield wiper blade according to claim 1, wherein the support member is a plastic material.

7. A windshield wiper blade according to claim 1, wherein the support member and the wiping strip are pieces cut from a continuous strip.

8. A windshield wiper blade according to claim 7, wherein the wiping strip is made of extruded rubber and the support member is made of extruded plastic material.

9. A windshield wiper blade according to claim 8, wherein the support member has been preformed in a mould prior to its assembly with the wiping strip.

10. A windshield wiper blade according to claim 1 wherein the inside surface of each coupling portion wall member further includes a plurality of rib portions and wherein the outside surface of each support member side wall includes a plurality of grooves, each of the ribs of the coupling portion wall inside surfaces being received in one of the grooves in the outside surface of its associated support member side wall.
