  • Patent number: 5287585
    Abstract: A windshield wiper apparatus for a vehicle includes a rotatably supported main shaft to which a wiper arm is secured, a main lever secured to the main shaft, a cam member arranged eccentrically about the main shaft, a plate turnably supported on the main lever, a subordinate lever having one end arranged about the cam member and another end connected to the plate, an arm turnably supported on the plate and having a joint to which a wiper drive mechanism is connected, and a turnover spring arranged between the plate and the arm for holding the arm at a predetermined position. If the wiper arm is moved by wind force during operation at high vehicle velocity, this motion is compensated for by adjusting the oscillation sweep of the arm in such a manner that the wiper arm will reverse direction at its normal upper reversal point. The wiper arm is thus prevented from striking the vehicle pillar, without reducing visibility through the windshield.

  • Patent number: 5201094
    Abstract: A wiper apparatus for a vehicle windshield having a linkage pivotably attached to a main driving lever. Linkage is also coupled to a motor to rotate main lever for rotating a main shaft limit positions for selecting resting place of wiper blade. An eccentric cam is rotatably mounted to the main shaft with an intermediate member rotatable relative to the cam and attached to the linkage. A driving mechanism rotates the cam to adjust the position of the linkage relative to the driving lever which in turn determines the upper and lower position of wiper blade.

  • Patent number: 5161280
    Abstract: A windshield wiper assembly provides variable contact pressure between the wiper blade and the windshield by utilization of a lever arm variably movable within a cam slot as the windshield wiper reciprocates across the windshield. A spring provides a bias force between the wiper arm and the lever arm of the assembly. The spring force acts through a moment arm to urge the wiper blade into contact with the windshield. The magnitude of the moment arm through which the spring bias force acts to urge the wiper blade into contact with the windshield is adjusted in accordance with the position of the wiper blade on the windshield as a result of the predetermined configuration of the cam slot which acts on the lever arm to which one end of the spring is attached. In this manner, the contact pressure between the wiper blade and the windshield is reduced at the extreme ends of the windshield wiper throw so as to reduce the noise typically associated with the windshield wiper reversing direction on the windshield.

  • Patent number: 5142728
    Abstract: A windshield wiper structure for a vehicle which has a wiper stroke adjusting mechanism. The wiper structure includes a main lever connected through a first pin with a wiper actuating rod and secured through a second pin to the wiper arm. The wiper actuating rod drives the main lever to swing about an axis of the second pin. A first eccentric shaft is provided about the first pin and a second eccentric shaft is provided about the second pin. The first eccentric shaft is connected with the wiper actuating rod so that a rotation of the first eccentric shaft causes a relative movement between the main lever and the wiper actuating rod. A second eccentric shaft is provided about the second pin and connected through an interconnecting lever with the first eccentric shaft. A stroke adjusting mechanism is provided for effecting a rotation of the second eccentric shaft.
