Articulated windshield wiper blade assembly

摘要

An articulated twin spline windshield wiper blade assembly for acceptance in the claws of a conventional windshield wiper arm assembly comprises a female spline having a circular channel therein for journaling of a cylindrical portion of a male spline. A portion of the male spline is truncated to define a channel for egress of water and debris and to minimize friction between the male and female splines.
