Abstract
An automotive wiper includes a frame supporting a blade. The frame is attached via an adapter to a wiper arm that presses and moves the wiper against and across the windshield. The wiper also includes a tension spring that is inserted along a rail portion of the blade for evenly distributing load along the blade onto the windshield. The adapter is disposed in the direction of a vertical axis (H) of the frame at a central portion thereof. The frame is offset by an adjustable angle θ from a horizontal axis (S) of the adapter taken at a sectional view of the wiper, whereby the frame is offset by an angle θ1 from its vertical axis, due to an offset of the frame and the adapter when the blade is pressed in its entirety against a windshield of a vehicle.
Claims10
An automotive wiper comprising:
- a frame supporting a blade which is adapted to closely contact a surface of an automotive windshield and is attached to a wiper arm for pressing and operating the wiper against and across the windshield via an adapter, and
- a tension spring having a predetermined tension and inserted along a rail portion of the blade for evenly distributing load along the blade onto the windshield,
- wherein said adapter is disposed perpendicularly to a longitudinal axis of the frame at a central portion thereof for a wiper arm mounted to a first arm which is longer than a second arm connected to said frame,
- the frame is maintained to be offset by an angle θ from a horizontal axis taken at a sectional view of the wiper with respect to the adapter, whereby the adapter is offset by an angle θ1 from a perpendicular axis of the wiper with said adapter having a width larger than a tensile member opposite said adapter due to an offset of the frame and the adapter the blade is adapted to be pressed against and to maintain substantially perpendicular to the surface of the automotive windshield, in operation.

An automotive wiper comprising:
- a frame supporting a blade which is adapted to closely contact a surface of an automotive windshield and is attached to a wiper arm for pressing and operating the wiper against and across the windshield via an adapter, and
- a tension spring having a predetermined tension and inserted along a rail portion of the blade for evenly distributing load along the blade onto the windshield,
- wherein
- a tensile member is in the form of the tension spring and has two ends and a central portion between the two ends, said tensile member extending symmetrically to both said ends from the central portion, and formed in a single one-piece tension spring for mounting to a wiper arm,
- said adapter is disposed perpendicularly to a longitudinal axis of the tensile member at a central portion thereof for the wiper arm to mount to said adapter having a width larger than a tensile member opposite said adapter,
- in operation, the tensile member is maintained to be offset by an angle θ from a horizontal axis taken at a sectional view of the wiper with respect to the adapter, whereby the adapter is offset by an angle θ1 from a perpendicular axis of the wiper, and due to an offset of the tensile member and the adapter the blade is adapted to be pressed against the surface of the automotive windshield.

An automotive wiper comprising:
- a frame supporting a blade that is adapted to closely contact a surface of an automotive windshield and being attached to a wiper arm for pressing and operating the wiper against and across the windshield via an adapter, and
- a tension spring having a predetermined tension and inserted along a rail portion of the blade for evenly distributing load along the blade onto the windshield,
- wherein
- a tensile member is in the form of the tension spring and has two ends and a central portion between the two ends, said tensile member extending symmetrically to both said ends said central portion and formed in a single one-piece tension spring for mounting to the wiper arm;
- and
- said adapter is disposed perpendicularly to a longitudinal axis of the tensile member at said central portion for the wiper arm to mount to said adapter having a width larger than a tensile member opposite said adapter,
- the tensile member is maintained to be offset by an angle θ from a horizontal axis resulting from a first arm being longer than a second arm of said frame as taken at a sectional view of the wiper with respect to the adapter, whereby the adapter is offset by an adjustable angle θ1 from a perpendicular axis of the wiper,
- due to an offset of the tensile member and the adapter the blade is pressed against the automotive windshield, and
- the blade is curved to deviate by an angle θ2 from a straight longitudinal axis thereof and maintains a substantially perpendicular angle with respect to the windshield and close contact with the windshield in operation, despite being offset from the perpendicular in conjunction with the tensile member.
