Abstract

A beam blade windshield wiper assembly including a wiping element that contacts the surface of the vehicle to be wiped. An elongated beam is operatively attached to the wiping element and has a pair of longitudinal ends. An airfoil assembly is operatively supported on the elongated beam. The assembly also includes a fluid manifold for distributing fluid across the surface to be wiped. The manifold has an inlet in fluid communication with a source of fluid, a plurality of outlets disposed along the longitudinal length of the manifold and an internal passage extending between the inlet and the outlets. A fluid manifold mounting system is adapted to support the fluid manifold on the elongated beam.

Claims

1. A beam blade windshield wiper assembly comprising:

a wiping element that contacts the surface to be wiped;

at least one elongated beam operatively attached to said wiping element and having a pair of longitudinal ends;

an airfoil assembly operatively supported on said elongated beam;

a fluid manifold for distributing fluid across the surface to be wiped, said manifold having an inlet in fluid communication with a source of fluid, a plurality of outlets disposed along the longitudinal length of said manifold and an internal passage extending between said inlet and said plurality of outlets; and

a fluid manifold mounting system adapted to support said fluid manifold on said elongated beam.

2. A windshield wiper assembly as set forth in claim 1 wherein said fluid manifold mounting system includes a body operatively adapted to be mounted to said elongated beam, a clip portion adapted to removably support said fluid manifold relative to said body, and a stabilizer extending between and interconnecting said body and said clip portion of said manifold mounting system.

3. A windshield wiper assembly as set forth in claim 2 wherein said windshield wiper system includes a coupler including first and second ends, said coupler mounted to said elongated beam between said longitudinal ends, said coupler acting to interconnect said wiper assembly to a wiper arm, said airfoil assembly having two segments disposed between said coupler and one of said pair of longitudinal ends of said elongated beam.

4. A windshield wiper assembly as set forth in claim 3 wherein said two segments of said airfoil assembly having a contoured profile, said first and second ends of said coupler having a contoured exterior surface that substantially corresponds to said contoured profile of said two segments of said airfoil assembly, said body of said manifold mounting system defining a spoiler portion that substantially corresponds to said contoured profile of said airfoil segments and said contoured exterior surface of said coupler, said spoiler portion adapted to utilize air flow to increase downward force on said windshield wiper assembly during operational movement across the surface to be wiped.

5. A windshield wiper assembly as set forth in claim 3 wherein said first and second ends of said coupler include a space, said body of said manifold mounting system including a pair of inwardly extending legs that are adapted to wrap around and operatively mount said body to said elongated beam, said legs defining nubs that are adapted to be received in nesting relationship with said space defined by said first and second ends of said coupler.

6. A windshield wiper assembly as set forth in claim 5 wherein said two airfoil segments each include interior terminal ends, said body of said manifold mounting system defining a female portion disposed adjacent said legs and that are designed to receive the interior terminal ends of each of said two airfoil segments in nesting relationship.

7. A windshield wiper assembly as set forth in claim 2 wherein said clip portion of said fluid manifold mounting system includes at least two legs that are disposed at an angle relative to one another to form a quasi-triangular space that is adapted to accommodate said manifold.

8. A windshield wiper assembly as set forth in claim 7 wherein said clip portion further includes a bottom wall that is designed to support said manifold and a sidewall disposed adjacent to one of said at least two legs.

9. A windshield wiper assembly as set forth in claim 8 wherein said clip portion may further include a plurality of compression ribs formed on the interior surface of said legs and said bottom and sidewalls, said compression ribs designed to engage the outer surface of said manifold and to be compressed by an interference fit therebetween to thereby retain said manifold in fixed relationship relative to said clip.

10. A windshield wiper assembly as set forth in claim 8 wherein said stabilizer includes a rib that extends between said body and said sidewall of said clip portion.

11. A windshield wiper assembly as set forth in claim 10 wherein said stabilizer may further include a hollow space defined between said rib and said sidewall of said body.

12. A beam blade windshield wiper assembly comprising:

a wiping element that contacts the surface to be wiped;

at least one elongated beam operatively attached to said wiping element having a pair of longitudinal ends;

a coupler mounted to said elongated beam between said longitudinal ends of said elongated beam, said coupler including first and second ends and acting to interconnect said wiper assembly to a wiper arm;

an airfoil assembly operatively supported on said elongated beam, said airfoil assembly having two segments with one of each of the two segments disposed between said coupler and one of said pair of longitudinal ends of said elongated beam;

a fluid manifold for distributing fluid across the surface to be wiped, said manifold having an inlet in fluid communication with a source of fluid, a plurality of outlets disposed along the longitudinal length of said manifold and an internal passage extending between said inlet and said plurality of outlets; and

a fluid manifold mounting system adapted to support said fluid manifold on said elongated beam, said fluid manifold system including a pair of bodies adapted to be operatively mounted to said elongated beam, each body being disposed between said first and second ends of said coupler and an adjacent segment of said airfoil assembly in nesting relation thereto, a clip portion adapted to removably support said fluid manifold relative to said body, and a stabilizer extending between and interconnecting said body and said clip portion of said manifold mounting system.

15. A windshield wiper assembly as set forth in claim 14 wherein said two airfoil segments each include interior terminal ends, each body of said manifold mounting system defining a female portion disposed adjacent said legs and that are designed to receive the interior terminal ends of each of said two airfoil segments in nesting relationship.

16. A windshield wiper assembly as set forth in claim 12 wherein said clip portion of said fluid manifold mounting system includes at least two legs that are disposed at an angle relative to one another to form a quasi-triangular space that is adapted to accommodate said manifold.

17. A windshield wiper assembly as set forth in claim 16 wherein said clip portion further includes a bottom wall that is designed to support said manifold and a sidewall disposed adjacent to one of said at least two legs.

18.
