WINDSCREEN WIPER BRUSH BELT (EMBODIMENTS) Russian patent published in 2020 - IPC B60S1/38 

FIELD: machine building.

SUBSTANCE: group of inventions relates to embodiments of a wiper brush strip, particularly a car wiper, and can be universally used for efficient cleaning of windshield of a vehicle in any weather conditions. Wiper blade of vehicle is made of elastomeric material with possibility of tight, without gaps, and fixed installation in holder, and along the entire length of the belt, in the scraper body, over its elongated contact part, a through hole of triangular cross-section passing through the centre is made, besides, the sides of the hole of the triangular cross section are parallel to the scraper sides, forming the scraper side walls. According to another embodiment of the band along the whole length of the through-hole of the triangular cross-section, its base is executed with one internal but not limited internal longitudinal symmetrical rib, the top of which is directed to the contact part of the scraper. Geometry and number of internal longitudinal ribs in the through hole of the scraper can be different. Also along the whole length of scraper cleaning edge is made with axisymmetric longitudinal cutout of triangular cross-section, forming two symmetrically located wedge-like projecting edges, passing along both longitudinal sides of elongated contact part of scraper or along entire length of scraper, cleaning edge on oblong contact part of scraper has rectangular shape.
