Abstract
A wiper device for a windshield of a vehicle comprising a wiper arm, a drive for oscillating the wiper arm, and an elongate flexible torsion rigid member for transmitting an oscillating movement of the wiper arm into pivotal movement of the wiping blade about an axis spaced from the windshield and extending substantially parallel thereto, the elongate flexible torsion rigid member including a fixed end having a longitudinal axis extending to the pivot axis of a pivot shaft attached to the other end of the elongate flexible member and connected to the wiping blade, at an angle less than 180.degree., and extending to the axis of a wiper shaft at an angle less than 90.degree., the pivot axis of the pivot shaft being a continuation of the longitudinal axis of the other end of the elongate flexible member.
Claims5
A wiper device for a windshield of a vehicle, said wiper device comprising an oscillating wiper arm having a free end;
- a wiping blade connected with said wiper arm at said free end of said wiper arm and pivotable about a pivot axis as a result of an oscillating movement of said wiper arm, said pivot axis being spaced from the windshield and extending substantially parallel thereto;
- and an elongate flexible member fixed at one end thereof and having at the other end thereof a pivot shaft defining said pivot axis and displaceable with said wiper arm and connected with said wiping blade for transforming the oscillating movement (.alpha.) of said wiper arm into a pivotal movement of said wiper blade, said one end and said pivot axis defining first and second longitudinal axes, respectively, said pivot axis forming an angle (.gamma.) with said first axis less than 180.degree..
