Embodiment Construction

[0022] Hereinafter, suggested embodiments of the present invention are given with reference to the accompanying drawings. Stripe 1 ( figure 1 (A)) comprises a base 2 adapted to be fixed in a holder 3 and a wedge-shaped scraper 4 with a protruding contact portion 5 with a sweeping edge 6 . The scraping part 4 is connected to the base part 2 through a connection assembly 7 . The strip 1 is fitted tightly (without gaps) and fixedly in the cage 3 . The side wall 9 of the wiper 4 is formed by a triangular cavity 8 which is located in the center of the strip, centered on the axis of the strip and extending throughout the entire length of the strip above the projection of the wiper. The thickness of each side wall 9 of the wiper 4 is proportional to the thickness of the protruding portion 5 of the wiper 4 . The plug 14 can be inserted into the through cavity 8 of the rubber strip 1 . The sweeping edge 6 has an axisymmetric longitudinal notch 15 with a triangular cross-section ext...

Abstract

The invention relates to vehicle windshield wiper blades. The present blade is made of an elastomeric material so as to be capable of being tightly and fixedly mounted in a holder. A through aperturehaving a triangular cross section runs along the full length of the blade in the middle of the body of a scraping element, above an elongated contact part of said scraping element. The sides of the aperture are parallel to the sides of the scraping element, forming lateral walls of the scraping element. A cleaning edge is provided with an asymmetrical longitudinal cutout having a triangular crosssection along the full length of the scraping element, said cutout forming two symmetrically disposed wedge-shaped protruding edges running along both longitudinal lateral sides of the elongated contact part of the scraping element. In one embodiment, along the full length of the through aperture, the base of the through aperture is provided with at least one symmetrical internal longitudinal rib,the apex of which is directed toward the contact part of the scraping element. The invention increases operating efficiency at sub-zero temperatures while having a simple structure and being simple to manufacture and use.

Description

technical field [0001] The present invention relates to a strip for wiper blades, designed primarily for motor vehicles, which can be used universally to effectively wipe windscreens in any weather conditions. Background technique [0002] Wiper strips for motor vehicles, such as automobiles, are used to effectively clear rain or snow from windshields and are generally made of resilient, flexible materials. Generally, the wiper strip comprises a base fixed in a cage and a working assembly, which presents a wiper portion with a sweeping edge on its contact portion. The scraper is connected to the base by connecting elastic components in such a way as to allow the working part of the rubber strip to appear as a scraper with a cleaning edge, which bends in one direction or the other, Thus changing the angle with respect to the transverse axis of the base, the wiper is moved on the glass surface in this way. When the wiper is in operation, one of the abutting ends of the rubbe...
