  • Patent number: 11358567
    Abstract: An automobile vehicle wiper arm system includes a wiper arm base rotatably connected to a fixed structural member. A wiper arm extension is slidably disposed to the wiper arm base during wiper arm base travel about an arc of travel. A motion link is rotatably connected to the wiper arm extension and is rotatably connected to the fixed structural member. The motion link induces the wiper arm extension to outwardly displace and inwardly displace opposite to the outward displacement during wiper arm base rotation about the arc of travel. A wiper blade is connected to the wiper arm extension and traverses an oval-shaped travel arc along a vehicle windshield by the slidable displacement of the wiper arm extension during wiper arm base rotation. A linkage group connects the wiper arm extension to a wiper motor with rotation of the wiper arm base induced by operation of the wiper motor.

  • Patent number: 6526620
    Abstract: A wiper apparatus includes a wiper blade pivotable between a waiting position and an upwardly turning position. The wiper blade has first and second blade holding members disposed in alignment. Mounted to the first and second blade holding members is a blade rubber for wiping a curved windshield. Each blade holding member has a non-pivotal member and a pivotal member which are disposed in alignment. The pivotal member is pivotally connected via a pin to the non-pivotal member. The blade holding member further includes a twisting member. The twisting member has a sub-arm and a cam connected to the sub-arm. The sub-arm is designed to cause the cam to pivot in such a manner that the pivotal member pivots in a lateral direction of the wiper blade in response to the pivotal movement of the wiper blade. The pivotal movement of the pivotal member twists the blade rubber. The thus twisted blade rubber has its opposite ends disposed on the windshield at right angles thereto.

  • Patent number: 6272717
    Abstract: A wiper apparatus employed in a windshield wiper system for supporting a pair of wiper elements via a wiper drive arm pivotably mounted proximate a vehicle windshield. The wiper apparatus comprises a drive arm attachment member adapted to be coupled with the wiper drive arm. In one embodiment, a pivot arm is pivotably secured to the drive arm attachment member about a pivot axis which intersects the windshield. The pivot arm is configured to carry the pair of wiper elements such that each of the wiper elements moves over a corresponding first arcuate path when the drive arm is rotated in a first direction and moves over a corresponding second arcuate path when the drive arm is rotated in an opposite direction. Each of the first and second paths of a first wiper element is different from each of the first and second paths of a second wiper element.

  • Patent number: 6253409
    Abstract: In a wiper device for vehicles, a wiper blade is rotatably connected to a wiper arm at a holding axis. A slider unit is attached to the wiper blade at a position being shifted from the holding axis. A lifter is disposed at the vehicle body at a position where the wiper device is stopped and the wiper blade is concealed. The slider unit runs onto the lifter to lift the wiper blade so that the wiper blade may be rotated on the holding axis until the wiper blade comes in contact with the wiper arm when the wiper device is stopped and the wiper blade is concealed. An elastic element for absorbing noise such as rubber or sponge is disposed between the wiper arm and wiper blade so that the wiper blade comes in contact with the wiper arm via the elastic element when the wiper blade is lifted.
