Patent ID: 7861363

Claim:
A beam blade windshield wiper assembly comprising: a rubber wiping element adapted to contact a surface to be wiped; an elongated beam having first and second longitudinal ends and lateral outside edges facing away from one another between said first and second longitudinal ends, said beam being of a resiliently flexible material to apply a force from an intermediate position between said first and second longitudinal ends to said first and second longitudinal ends; a retainer including a plate, a pair of legs depending from said plate to operatively engage a portion of said rubber wiping element and a pair of arms extending from said plate in a direction opposite to said legs and wrapping around and engaging said lateral outside edges of said beam so as to retain said beam in the lateral direction, said arms cooperate with said plate to define a space that is operatively engaged by said elongated beam; and an airfoil having an attachment portion and an upper portion extending between first and second distal ends, said attachment portion is integrally attached to said upper portion and is operatively attached to said retainer, said upper portion including a solid base having a leading edge that extends from said base toward said wiping element and a spoiler that is solid in cross-section and extends from said base in a manner opposite to said leading edge, wherein said attachment portion, said retainer and said elongated beam cooperate to define a cavity adapted to provide flexibility between said airfoil and said retainer during operational movement across the surface to be wiped.
