WIPER FLAT BLADE WITH AERODYNAMIC REFLECTOR Russian patent published in 2009 - IPC B60S1/38 

FIELD: automotive industry.

SUBSTANCE: invention relates to wiper blades. Wiper blade (10) comprises central lengthwise stiffening element (20), cleaner (14) for window (22, 24) arranged above and along aforesaid central element (20) and furnished with lower lengthwise cleaning edge (40) interacting with window (24). It comprises also the element making aerodynamic reflector (16) arranged lengthwise and above central element 20, which features, in its crosswise vertical plane, triangular profile (AE-FM-MA). The said profile comprises lower horizontal base side (AM), front side (AE) that limits windward surface of the said aerodynamic reflector (16). Front side (AE) comprises lower section (AC), intermediate section (CD) representing, in fact, a concave arc, top end section (DE) and rear vertical side (FM) that limits the reflector leeward side and is connected, via side (EF), with front side (AE). Side (EF) limits upper lengthwise edge (42) of the reflector top free end. Ratio (H/L) varies from 1.5 to 2.0. The said ratio defines the dependence between total height (H) of wiper blade (10) that separates upper edge (42) of aerodynamic reflector (16) from lower cleaning edge (40), and crosswise width (L) of wiper blade (10) measured in the plane of stiffening element 20.

EFFECT: improved aerodynamics.
