Abstract: An articulated twin spline windshield wiper blade assembly for acceptance in the claws of a conventional windshield wiper arm assembly comprises a relative high durometer polymeric female spline having a circular channel therein for journaling of a male spline of a relatively low durometer elastomeric material. The female spline has a pair of oppositely directed flanges that are accepted in the claws of the wiper arm assembly and lie in a plane containing the central axis of the circular channel therein to minimize the moment of inertia of the female spline about an axis extending at a right angle to the central axis of the channel therein and parallel to a surface to be wiped.
