Abstract
A wiper blade assembly has an elongate carrier strip for supporting on a windshield wiper arm, a pair of spaced, flexible wiper blades depending parallel to one another from the carrier strip with a gap between the blades, and a cleaning member supported in the gap between the blades, the cleaning member having a base portion and a plurality of conical cleaning tips depending from the base portion. The cleaning tips are shorter than the wiper blades so that they do not contact a windshield surface until the wiper blades are deformed in a wiping action, and are more rigid than the blades.
Claims16
A wiper blade assembly, comprising:
- an elongated carrier strip adapted for mounting on a windshield wiper arm;
- a wiper blade member having mounting means for releasably mounting the wiper blade member on the carrier strip;
- the wiper blade member comprising a flat, elongated base portion having a longitudinal axis along the length of the base portion and opposite longitudinal sides;
- a pair of spaced, elongated flexible wiper blades depending downwardly and parallel to one another from opposite sides of said base portion along the length of the base portion to leave a gap between the wiper blades, each wiper blade having a lower edge for contact with a windshield surface and a predetermined length between said base portion and lower edge in a direction transverse to the longitudinal axis of the base portion;
- a plurality of conical cleaning tips depending downwardly from a central region of said blade member in the gap between the wiper blades, the base portion, wiper blades and conical cleaning tips being formed integrally in one-piece from the same elastomeric material, the cleaning tips each having a length less than the length of said wiper blades;
- and
- the shape and dimensions of the wiper blades and cleaning tips being such that the cleaning tips are more rigid than the wiper blades.

Windshield wiper blade device, comprising:
- an elongated carrier strip having mounting means for securing the carrier strip to a windshield wiper arm;
- a pair of separate, elongated, flexible wiper blades each having a base portion, a lower edge for contacting a windshield surface, and tapering opposite side portions extending from the base portion to the lower edge, the base portion of each wiper blade having an upper mounting flange projecting upwardly and extending longitudinally along said base portion for releasable engagement with said carrier strip;
- said carrier strip comprising support means for engaging said mounting flanges to maintain said blades parallel to one another with a gap between the blades;
- and
- a cleaning member of elastomeric material supported in the gap between the wiper blades, the cleaning member comprising an elongated cleaning member base portion having a mounting flange projecting upwardly for releasable engagement with said carrier strip, and a plurality of conical cleaning tips depending downwardly from said cleaning member base portion, the tips extending parallel to the wiper blades, and each cleaning tip having a length less than that of the wiper blades.
