A beam blade windshield wiper assembly (10) including an elongated backbone (12) having a longitudinal beam length extending between first (20) and second longitudinal ends (22) of the backbone, and upper surface (26) and an opposed mounting surface (28) with first and second sides (30, 32) extending there between. The distance between the upper surface (26) and the mounting surface (28) on the backbone (12) defines a thickness thereof. Similarly, the distance between the first (30) and second sides (32) defines the width of the backbone. A wiper element is mounted to the mounting surface (28) of the backbone (12) and extends for a substantial portion of its longitudinal beam length. The backbone (12) defines an X-axis extending longitudinally, a Y-axis extending transverse to the X-axis and through the upper surface (26) and the mounting surface (28) so as to define a Z-axis extending perpendicular to the X-Y plane. Furthermore, the width of the backbone (12) varies between the first (20) and second ends (22) and the thickness of the backbone (12) is constant. In addition, the backbone (12) varies or curves from the X-axis in the direction of the Z-axis in the plan view. |
