VEHICLE WINDSHIELD WIPER BLADE Russian patent published in 2005 - IPC

FIELD: transport engineering; windshield wipers.

SUBSTANCE: proposed blade 10 has elastic elongated rubber tape 20 pressed by working edge to glass. Said tape is provided with longitudinal slot 29, 30 from both longitudinal sides which are arranged in plane mainly parallel to glass 14 at a distance from glass. Bridge 34 is found between slots. Each said longitudinal slot accommodates spring strip 36, 38 being element of elongated flexible holder in form of strip.
