Abstract
A vehicle, including: a windshield; and a first wiper arm including a first segment and a second segment attached to the first segment, wherein the first wiper arm is operatively attached to the vehicle at a first side of the vehicle such that the first wiper arm is rotatable about a first axis of rotation between at least an outer position and an inner position, and wherein the first wiper arm is shaped such that, when the first wiper arm is in the outer position, the first segment extends from the first axis of rotation away from a width center of the vehicle, and the second segment extends from the first segment at least partly along a height direction of the vehicle.
Claims20
A vehicle, comprising:
- a windshield;
- and
- a first wiper arm comprising a first segment and a second segment attached to the first segment,
- wherein the first wiper arm is operatively attached to the vehicle at a first side of the vehicle such that the first wiper arm is rotatable about a first axis of rotation between at least an outer position and an inner position, and
- wherein the first wiper arm is shaped such that, when the first wiper arm is in the outer position, the first segment extends from the first axis of rotation away from a width center of the vehicle, and the second segment extends from the first segment at least partly along a height direction of the vehicle.
A vehicle, comprising:
- a windshield;
- a first wiper arm operatively attached to the vehicle at a left side of the windshield such that the first wiper arm is rotatable about a first axis of rotation between at least an outer position and an inner position;
- and
- a second wiper arm operatively attached to the vehicle at a right side of the windshield such that the second wiper arm is rotatable between at least an outer position and an inner position,
- wherein the first and second wiper arms are shaped and sized to wipe, during a cycle of each of the first and second wiper arms, a wipe area of the windshield having an upper edge that is, at a width center of the windshield, separated from a lower edge of the windshield by at least 60% of a distance between the lower edge of the windshield and an upper edge of the windshield at the width center of the windshield.
The vehicle of claim 14, wherein extensions of the first and second axes of rotation meet and form an angle of at least 20 degrees.
A pair of wiper arms for a vehicle, the pair of wiper arms comprising:
- a first wiper arm, comprising:
- a first segment configured to rotatably attach to an axis of rotation at a proximal end of the first segment, wherein the first segment comprises a first part extending along a first axis from the proximal end of the first segment, and a second part extending along a second axis from the first part of the first segment to a distal end of the first segment, and
- a second segment attached to the distal end of the first segment, and configured to attach to a wiper blade at an inner side of the second segment;
- and
- a second wiper arm, comprising:
- a third segment configured to rotatably attach to a vehicle about an axis of rotation at a proximal end of the third segment, wherein the third segment comprises a third part extending along a third axis from the proximal end of the third segment, and a fourth part extending along a fourth axis from the third part of the third segment to a distal end of the third segment, and
- a fourth segment attached to the distal end of the third segment, and configured to attach to a wiper blade at an inner side of the fourth segment,
- wherein a coordinate system is defined by an X-axis, a Y-axis, and a Z-axis, which are mutually orthogonal,
- wherein the first wiper arm is shaped such that, when the first axis extends from the proximal end of the first segment along an X-axis direction and the second axis extends from the first part of the first segment at least partly in a Y-axis direction, the inner side of the second segment faces at least partly in a negative Z-axis direction, and
- wherein the second wiper arm is shaped such that, when the third axis extends from the proximal end of the third segment along a negative X-axis direction and the fourth axis extends from the third part of the third segment at least partly in the Y-axis direction, the inner side of the fourth segment faces at least partly in the negative Z-axis direction.
