1. A vehicle wiper blade assembly comprising:
- an elongated wiper blade adapted for wiping a windshield;
at least one support member supporting the wiper blade at different points along the length thereof;
at least one holder pivotally connected to the support member;
a cover covering the support member, the holder, and a portion of the wiper blade;
an elongated primary lever pivotally connected to the holder with the cover situated therebetween, wherein the holder is pivotal on said support member about a first axis substantially transverse to the primary lever and the primary lever is pivotal on said holder about a second axis substantially perpendicular to the first axis;
a blade spoiler connected to the primary lever and adapted to apply pressure to the wiper blade against the windshield when the vehicle is moving.

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.
