Abstract

A windshield wiper blade cover and a wiper blade having same. The windshield wiper blade cover being capable of being disposed on the top side of a beam of a wiper blade, and comprising two longitudinal sides, two outer ends and a top surface, where the top surface of the cover has a base portion having a height and a raised portion having a height, the height of the raised portion is greater than the height of the base portion, and the height of the raised portion gradually decreases as the raised portion approaches the outer ends of the cover. The wiper blade comprising a cover as described above, a beam having two ends, two longitudinal sides, a top side and a bottom side, a central bridge disposed on the top side of the beam, a wiper strip disposed on the bottom side of the beam, and the cover disposed on the top side of the beam.

Claims

1. A wiper blade comprising:

a beam having two ends, two longitudinal sides, a top side and a bottom side;

a central bridge disposed on the top side of the beam;

a wiper strip disposed on the bottom side of the beam;

a cover having two longitudinal sides, two outer ends and a top surface;

wherein;

the cover is disposed on the top side of the beam;

the top surface of the cover has a base portion having a height and a raised portion having a height wherein the height of the raised portion is greater than the height of the base portion; and

the height of the raised portion gradually decreases as the raised portion approaches the outer ends of the cover.

2. The wiper blade of claim 1 wherein the raised portion forms a wind deflection structure having a generally triangular shape when viewed in cross section.

3. The wiper blade of claim 1 wherein the cover is symmetric in shape across a plane that is transverse to the two longitudinal sides of the cover.

4. The wiper blade of claim 1 wherein the cover is symmetric in shape across a plane that extends vertically through a longitudinal axis of the cover.

5. The wiper blade of claim 1 wherein the raised portion has an apex that merges with the base portion before the outer ends of the cover.

6. The wiper blade of claim 1 wherein the cover is provided with two claws that run along the two longitudinal sides of the cover, wherein the longitudinal sides of the beam are disposed in the two claws.

7. The wiper blade of claim 6 wherein the claws end in the vicinity of the outer ends of the cover, and wherein the outer ends of the cover are provided with a structure that secures the ends of the beam.

8. The wiper blade of claim 1 wherein the cover is a unitary structure and is provided with a hole to accommodate the central bridge of the wiper blade.

9. The wiper blade of claim 1 wherein the cover comprises two sections, each section having an inner end, wherein a gap is provided between the inner ends of the two sections to accommodate the central bridge.

10. The wiper blade of claim 9 wherein a cap is provided that covers the gap and the inner ends of the two sections.

11. A wiper blade cover comprising two longitudinal sides, two outer ends and a top surface;

wherein;

the cover is capable of being disposed on the top side of a beam;

the top surface of the cover has a base portion having a height and a raised portion having a height wherein the height of the raised portion is greater than the height of the base portion; and

the height of the raised portion gradually decreases as the raised portion approaches the outer ends of the cover.

12. The wiper blade cover of claim 11 wherein the raised portion forms a wind deflection structure having a generally triangular shape when viewed in cross-section.

13. The wiper blade cover of claim 11 wherein the cover is symmetric in shape across a plane that is transverse to the two longitudinal sides of the cover.

14. The wiper blade cover of claim 11 wherein the raised portion has an apex that merges with the base portion before the outer ends of the cover.

15. The wiper blade cover of claim 11 wherein the cover is provided with two claws that run along the two longitudinal sides of the cover, wherein the claws are capable of receiving the longitudinal sides of a beam.

16. The wiper blade of claim 15 wherein the claws end in the vicinity of the outer ends of the cover, and wherein the outer ends of the cover are provided with a structure capable of securing the ends of the beam.

17. The wiper blade cover of claim 11 wherein the cover is a unitary structure and is provided with a hole to accommodate the central bridge of the wiper blade.

18. The wiper blade cover of claim 11 wherein the cover comprises two sections, each section having an inner end, wherein a gap is provided between the inner ends of the two sections to accommodate a central bridge of a wiper blade.

19. The wiper blade cover of claim 18 wherein the cover further comprises a cap that covers the gap and the inner ends of the two sections.

20. A wiper blade comprising a beam having two ends, a central bridge disposed on the beam, and a cover, wherein the cover has a spoiler that tapers from a highest point in the vicinity of the central bridge to a lowest point in the vicinity of the ends of the beam.
