FIN-INTEGRATED WIPER BLADE FOR PREVENTING INFILTRATION OF SNOW INTO PRIMARY LEVER, YOKE LEVER, AND BACKING PLATE BY CLOSING RECEIVING SPACE OF COVER BY BASE OF BLADE RUBBER

摘要

PURPOSE: A fin-integrated wiper blade is provided to restrict snow from flowing into a space formed between the wiper blade and a lever, and to secure good wiping performance in the high-speed traveling of a vehicle. CONSTITUTION: A fin-integrated wiper blade(10) is composed of an elongate blade rubber(12) for wiping a wiping surface(W); at least one backing plate(18) extended in the longitudinal direction of the blade rubber, connected with the blade rubber, curved perpendicularly to the wiping surface, and composed of a spring plate material having the elasticity of a spring in the perpendicular direction for the wiping surface; at least one retaining lever for holding the blade rubber and the backing plate; and a cover member(32) comprising an opening unit(35) formed at an end(37) of a base, and front and rear walls(34,36) connected to each other to form a cap-shaped elongate body for receiving the retaining lever and the backing plate. The front wall has an inclined outer surface inclined to the wiping surface to form a fin.
