Abstract

A wiper blade having a wiper strip having a wide portion and a lip, and an elongate backing element. The backing element having a top portion, and two opposing legs that descend from the top portion, such that each opposing leg has a claw which extends towards the other opposing leg. A gap formed between the claws that is narrower than a width of the wide portion of the wiper strip. The claws, legs, and top portion define a wiper strip cavity sized to receive the wide portion wiper strip.

Claims

1. A wiper blade comprising:

a wiper strip having a wide portion and a lip;

an elongate backing element having a top portion, and two opposing legs that descend from the top portion, wherein each opposing leg has a claw which extends towards the other opposing leg, such that a gap between the claws is narrower than a width of the wide portion of the wiper strip, wherein the claws, legs, and top portion define a wiper strip cavity sized to receive the wide portion wiper strip.

2. The wiper blade of claim 1 further comprising a wiper sleeve having a base from which two opposing legs descend, wherein each leg of the wiper sleeve has a claw that extends towards the opposing leg of the wiper sleeve, the wiper sleeve base, legs and claws, defining a sleeve cavity, where the wiper sleeve cavity is sized to receive a top strip of the wiper strip.

3. The wiper blade of claim 2 wherein sleeve further comprises a tongue on the top surface of its base, and wherein the backing element further comprises an upper recess sized to receive the tongue.

4. The wiper blade of claim 1 wherein the wiper strip further comprises an intermediate portion having a securing groove;

wherein the gap between the claws is sized to receive the intermediate portion the wiper strip by engaging the securing groove

5. The wiper blade of claim 1 wherein the backing element further comprises at least one vertical projection extending downward from the legs.

6. The wiper blade of claim 5 wherein the at least one vertical projection extends even with, the bottom of the claws.

7. The wiper blade of claim 6 further comprising a cover having at least one notch that engages the at least one vertical projection.

8. The wiper blade of claim 1 further comprising a cover having a top surface from which two opposing legs descend, and two end walls that join the top surface and legs of the cover at respective ends of the cover;

wherein the cover is disposed on and covers the backing element.

9. The wiper blade of claim 8 wherein in the backing element further comprises a first end and a second end, each end having an end projection, and the end walls of the cover further each comprise a securing recess which receives one of the end projections of the backing element.

10. The wiper blade of claim 8 wherein each opposing leg of the cover further comprises a bottom claw extending towards the opposing leg of the cover.

11. The wiper blade of claim 1 further comprising a mounting base having a base section that is secured on the top portion of the backing element.

12. The wiper blade of claim 11 wherein the backing element has a central recess, wherein the mounting base has a structure extending below the base portion wherein the central recess is sized and shaped to the structure.

13. The wiper blade of claim 12 wherein the mounting base further comprises two opposed vertical side walls extending above and below the base, wherein a rivet is disposed between the opposed vertical side walls, and wherein the structure comprises the portion of the vertical side walls extending below the base.

14. The wiper blade of claim 11 further comprising a cover having a central recess that encircles the mounting base.

15. The wiper blade of claim 11 wherein the base of the mounting base further comprises at least one securing peg, and the top portion of the backing element comprises at least one securing hole, such that at least one securing hole receives and secures the at least one securing peg.

16. The wiper blade of claim 1 further comprising a cover having top surface comprising a spoiler.

17. The wiper blade of claim 1 further comprising a cover having interior projections that engage complementary detents in the backing element.

18. The wiper blade of claim 17 wherein the interior projections are T-shaped.

19. A wiper blade comprising:

a wiper strip having a wide portion and a lip;

an elongate backing element having a top portion, and two opposing legs that descend from the top portion, wherein each opposing leg has a claw which extends towards the other opposing leg, such that a gap between the claws is narrower than a width of the wide portion of the wiper strip, wherein the claws, legs, and top portion define a wiper strip cavity sized to receive the wide portion wiper strip;

a mounting base having a base section that is secured on the top portion of the backing element;

a cover having a top surface from which two opposing legs descend, and two end walls that join the top surface and legs of the cover at respective ends of the cover;

wherein each opposing leg of the cover comprises a bottom claw extending towards the other opposing leg of the cover, wherein the cover is disposed on and covers the backing element, and wherein the cover has a central recess that encircles the mounting base.

20. A wiper blade comprising:

a wiper strip having a top strip;

an elongate backing element having a top portion, and two opposing legs that descend from the top portion, a first rib portion and a second rib portion extending between the opposing legs along a bottom surface of the top portion;

wherein the first rib portion comprises an opposed legs descending from the first rib portion, each opposing leg of the first rib portion having a claw that extends towards the other opposing leg of the first rib portion, such that the opposing legs and claws of the first rib portion secure the wiper strip such that the top strip of the wiper strip is held against the first rib portion.
