Abstract: A three piece wiper blade mechanism for mounting to a conventional automotive wiper blade assembly featuring an elongated arm having plural pairs of C-configured claw arms for removably attaching to the mechanism. The three piece wiper mechanism comprises a first, elongated plastic housing, preferably permanently received within the claw arms, a second, elongated plastic insert for slidably engaging the first housing, and a rubberized wiper blade element in fixed engagement with the second insert. By the use of plastic sliding on plastic, a new wiper blade element and second insert may be readily inserted into the first plastic housing, especially for the do-it-yourself mechanic.
