ABSTRACT:
An articulated twin spline windshield wiper blade assembly includes an elongated, resilient, thin-walled polymeric female spline of relatively high durometer having a generally planar backbone, and two opposing arcuate spline legs which extend downwardly from the backbone and cooperate with the backbone to define a cylindrical spline channel. The wiper blade assembly further includes an elastomeric male spline having a cylindrical body portion rotatably journaled within the spline channel of the female spline. The male spline further includes a neck portion depending from the body portion, and a wiping portion depending from the neck portion. The wiping portion includes opposing wiping edges which are alternately engagable with a surface to be wiped upon rotation of the male spline within the spline channel. The spline legs are specifically designed so that they are sufficiently resilient to permit flexure of the spline legs relative to the backbone during rotation of the male spline so as not to bind the male spline during rotation thereof, particularly when the spline contours to a curved windshield. To further reduce friction and resistance to rotation, the cylindrical body portion of the male spline is truncated at its uppermost edge. An ancillary benefit of the truncation is the discharge of water and debris outwardly of the spline channel at the end of the spline channel.
