ABSTRACT:
A wiper blade is provided and has a pressure distributing rod with a longitudinal groove having a substantially T-shaped form and a wiping element. The T-shaped form of the groove has a horizontal bar and a vertical bar. The wiping element has an upper portion located in the horizontal bar of said T, a medium portion partially located in the vertical bar of said T and a lower portion forming a wiping lip. The vertical bar of said T is tapered in a direction opposite to the surface to be wiped with the junction between the vertical bar and the horizontal bar of said T is defined by rounded curves. The upper portion of the wiping element is linked to the medium portion of the wiping element by a reduced portion which, in cross-section, is defined by rounded curves. The taper of the vertical bar of said T and the rounded curves between the horizontal and vertical bars nest in the rounded curves in the reduced portion of the wiping element whereby the wiping element is permitted to pivot about the rounded curves of the pressure distributing rod.
