Abstract
A windshield wiper assembly for an automobile, comprising a wiper arm, a wiper blade, a plurality of double claw fixtures pivotally mounted onto the wiper arm and adapted to support the wiper blade on the wiper arm, and an actuator adapted to selectively induce rotation of the wiper blade along a longitudinal axis of the wiper blade relative to the wiper arm, each of the double claw fixtures adapted to rotatably support the wiper blade.
Claims18
A windshield wiper assembly for an automobile, comprising:
- a wiper arm;
- a wiper blade having first and second distal ends;
- a plurality of double claw fixtures pivotally mounted onto the wiper arm and adapted to support the wiper blade on the wiper arm;
- and
- an actuator including a first push rod having a first distal end engaging the first distal end of the wiper blade and a second push rod having a first distal end engaging the second distal end of the wiper blade, wherein the actuator is adapted to selectively push the first push rod toward the first distal end of the wiper blade and to push the second push rod toward the second distal end of the wiper blade to twist the first and second distal ends of the wiper blade to induce rotation of the wiper blade along a longitudinal axis of the wiper blade relative to the wiper arm, each of the double claw fixtures adapted to rotatably support the wiper blade.

A windshield wiper assembly for an automobile, comprising:
- a wiper arm;
- a wiper blade having first and second distal ends;
- a plurality of double claw fixtures pivotally mounted onto the wiper arm, wherein each fixture is adapted to rotatably support the wiper blade on the wiper arm;
- an actuator adapted to selectively twist the first and second distal ends of the wiper blade to induce rotation of the wiper blade along a longitudinal axis of the wiper blade relative to the wiper arm;
- and
- the wiper blade includes metallic splines extending longitudinally from the first distal end of the wiper blade to the second distal end of the wiper blade, the actuator including a first electric coil positioned on the wiper arm adjacent the first distal end of the wiper blade and a second electric coil positioned on the wiper arm adjacent the second distal end of the wiper blade, the first and second coils adapted to induce the twist to the first and second distal ends of the wiper blade, inducing the rotation of the wiper blade along the longitudinal axis relative to the wiper arm.
