ABSTRACT:
A vehicle wiper blade assembly has a cover for covering blade support members, which support a wiper blade at different points therealong, and for covering portions of the wiper blade. A blade spoiler can be adjustably attached either to a primary lever, which connects the support members with the cover to a wiper arm, or to the wiper arm. The spoiler presses the wiper blade against the windshield when the vehicle is moving, improving the wiping efficiency. The lower edge of the spoiler is positioned nearer to the windshield than to the to the bottom of the cover to improve air and debris (such as snow) flow. The support members are also pivotally coupled to both ends of the primary lever to improve the wiper blade efficiency.
