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.

    本发明涉及车辆挡风玻璃的雨刮器叶片。该叶片由弹性体材料制成以能够被紧密且固定地安装在保持架中。具有三角形横截面的通孔在刮擦元件的细长接触部分上方,在所述刮擦元件的主体的中间沿着叶片的整个长度延展。孔的侧面平行于刮擦元件的侧面,从而形成刮擦元件的侧向壁。清扫边缘设有非对称纵向切口,该非对称纵向切口沿着刮擦元件的整个长度具有三角形横截面,所述切口形成两个对称设置的楔形突出边缘,楔形突出边缘沿着刮擦元件的细长接触部分的两个纵向侧面延展。在一个实施例中,沿着通孔的整个长度,通孔的基部设有至少一个对称的内部纵向肋,该内部纵向肋的尖端朝着刮擦元件的接触部分定向。本发明提高了在零下温度下的运行效率,同时具有简单的结构并且易于制造和使用。
