Vehicle windshield wiper blade

Abstract

This invention relates to tape of glass cleaning brushes, mainly to automobile windscreen wipers, and can be used universally for efficient cleaning of the windscreen of a motor vehicle in any weather conditions. The windscreen cleaning brush tape is made of an elastomeric material that can be firmly, without any gaps and installed motionless in the holder, while an axisymmetric cavity, triangular in its cross-section, runs along the entire length of the tape through the body of the scraper above its stretched out portion, and the sides of the triangular cavity run parallel to the sides of the scraper, forming sidewalls of the scraper. In another claim of this invention, the base of the triangular cavity carries at least one longitudinal symmetric rib, the vertex of which is directed towards the contacting portion of the scraper. Geometry and quantity of longitudinal ribs inside the cavity may vary. Also, the cleaning edge carries an axisymmetric longitudinal notch of triangular cross-section, which forms two symmetrically protruding wedge-shaped edges, running along both longitudinal sides of the stretched out contacting portion of the scraper. Higher efficiency of windscreen wipers motor vehicles at sub-zero temperatures is achieved. The offered tape for wipers is simple in structure and production method and is easy to use.
