Patent ID: 7735184

Claim:
A wiper blade for scrubbing and cleaning a surface of glass and polymeric windows, comprising: an elongated body made of elastomeric material, said body defining a base portion and a blade portion projecting therefrom, said blade portion having an inside surface and an outside surface, said blade portion having a terminal end that in operation is in close proximity to the window surface; an array including at least one row extending along the blade portion, each row including a plurality of discrete, specifically shaped scrubbing configurations that are independent and non-continuous along the length of the blade portion protruding from a said outside surface of said blade portion, each scrubbing configuration having a reduced radii side and being tapered towards a free end thereof, whereby said reduced radii side is designed to be substantially directed towards the window surface at a angle and provide substantially point contact at its free end with the window surface, as the blade flexes in operation, to engage and impinge debris on said window; whereby at least one of the plurality of specifically shaped scrubbing configurations are located near the terminal end of the blade portion; whereby each of the plurality of specifically shaped scrubbing configurations has, in a transverse cross section as it protrudes from the outside surface, a shape defining at least one linear side, and said inside surface having a substantially smooth surface, said inside surface designed to collect and remove moisture and debris from the window surface.
