Abstract
A windshield wiper for an automotive vehicle having an elongated base and an elongated flexible blade extending outwardly in a first direction from the base. The blade has a free edge adapted to contact a windshield on an automotive vehicle. An elongated scraper also extends outwardly from the base at an acute angle relative to the blade so that a free edge of the scraper is spaced from and generally parallel to the free edge of the blade. The scraper is constructed of a material more rigid than the blade to remove adhered debris from the windshield upon transverse movement of the windshield wiper.
Claims2
A windshield wiper comprising:
- an elongated base,
- an elongated flexible blade constructed of an elastomeric material extending outwardly in a first direction from said base, said blade have a free edge,
- a single elongated scraper extending outwardly from only one side of said base at an acute angle relative to said first direction so that a free edge of said scraper is spaced from and generally parallel to said blade free edge, said scraper being constructed of a continuous material having a different durometer than said blade so that said scraper is more rigid than said blade,
- wherein said base is constructed of a flexible material so that said scraper pivots between a windshield contacting position upon transverse movement of the wiper in one direction, and a position spaced apart from the windshield upon movement of the wiper in a transverse direction opposite from said one direction.
- wherein said base, said blade and said scraper are of a one piece integral construction, and
- wherein said scraper material extends down through a center of said blade to an end positioned within the blade and adjacent said free edge of said blade.
