AIRFOIL FOR HYBRID WIPER ASSEMBLY
An airfoil for a hybrid wiper assembly includes an airfoil for a hybrid wiper assembly including a body extending longitudinally and having a spoiler that tapers outwardly from the body toward a terminal point to define a varying profile along a longitudinal curved surface thereof. The airfoil also includes a plurality of inwardly extending claws extending longitudinally and forming grooves between the body and the claws near each longitudinal end thereof and adapted to receive support structure of the hybrid wiper assembly.
1 . An airfoil for a hybrid wiper assembly comprising:
a body extending longitudinally and having a spoiler that tapers outwardly from said body toward a terminal point to define a varying profile along a longitudinal curved surface thereof; and
a plurality o f laterally inwardly extending claws forming grooves between said body and said claws near each longitudinal end thereof and adapted to receive support structure of said hybrid wiper assembly.
2 . An airfoil as set forth in claim 1 wherein said claws extend longitudinally a predetermined length less than a length of said airfoil.
3 . An airfoil as set forth in claim 1 wherein said claws comprises a pair of opposed claws extending laterally inwardly.
4 . An airfoil as set forth in claim 3 wherein said pair of opposed claws form a space therebetween.
5 . An airfoil as set forth in claim 1 wherein said claws comprise a pair of opposed claws at one longitudinal end and a pair of opposed claws at the other longitudinal end.
6 . An airfoil as set forth in claim 1 wherein said claws extend longitudinally a distance greater than a laterally inwardly distance.
7 . An airfoil as set forth in claim 1 wherein said grooves are generally rectangular in shape.
8 . An airfoil as set forth in claim 1 wherein said claws are generally rectangular in shape.
9 . An airfoil as set forth in claim 1 wherein said body is solid, integral, unitary, and one-piece.
10 . An airfoil as set forth in claim 1 wherein said body is made of a plastic material.
11 . A hybrid wiper assembly comprising:
a wiping element adapted to contact a surface to be wiped;
at least one elongated beam defining a longitudinal axis, said beam acting to support said wiping element and having opposed longitudinal ends;
an airfoil operatively mounted to said beam and extending between said longitudinal ends of said beam; and
said airfoil comprising a body extending longitudinally and having a spoiler that tapers outwardly from said body toward a terminal point to define a varying profile along a longitudinal curved surface thereof, and a plurality of laterally inwardly extending claws forming grooves between said body and said claws near each longitudinal end thereof to receive said beam.
12 . A wiper assembly as set forth in claim 11 wherein said claws extend longitudinally a predetermined length less than a length of said airfoil.
13 . A wiper assembly as set forth in claim 11 wherein said claws comprises a pair of opposed claws extending laterally.
14 . A wiper assembly as set forth in claim 13 wherein said pair of opposed claws form a space therebetween.
15 . A wiper assembly as set forth in claim 11 wherein said claws comprise a pair of opposed claws at one longitudinal end and a pair of opposed claws at the other longitudinal end.
16 . A wiper assembly as set forth in claim 11 wherein said claws extend longitudinally a distance greater than a laterally inwardly distance.
17 . A wiper assembly as set forth in claim 11 wherein said claws are generally rectangular in shape.
18 . A wiper assembly as set forth in claim 11 wherein said body is solid, integral, unitary, and one-piece.
19 . A wiper assembly as set forth in claim 11 wherein said body is made of a plastic material.
20 . A hybrid wiper assembly for a windshield of a vehicle comprising:
a wiping element adapted to contact a surface to be wiped;
at least one elongated beam defining a longitudinal axis, said beam acting to support said wiping element and having opposed longitudinal ends;
a pair of airfoils operatively mounted to said beam and extending between said longitudinal ends of said beam;
each of said air foils comprising a body extending longitudinally and having a spoiler that tapers outwardly from said body toward a terminal point to define as varying profile along a longitudinal curved surface thereof, and a plurality of laterally inwardly extending claws extending longitudinally and forming grooves between said body and said claws near each longitudinal end thereof to receive said beam.
