摘要： A windshield wiper system for automotive vehicles includes a mechanism for causing a wiper blade assembly to swing, relative to the wiper arm, between an extended position of the wiper blade assembly and a retracted position of the wiper blade assembly. More specifically, the mechanism causes a link, which is attached to the wiper blade assembly, to swing as the wiper arm moves into and out of the hidden park position. A first embodiment includes a "four-bar linkage" which transfers to oscillatory movement of a drive arm of a wiper system to pivotal movement of the link over a limited range of motion of the drive arm corresponding to movement of the wiper blade assembly into and out of the hidden park position. A second embodiment includes a cam element which selectively engages a fixed pin over a range of motion of the drive arm corresponding to movement of the wiper blade assembly into and out of the hidden park position.

摘要： A windshield wiper system for automotive vehicles includes a power source and a driver for causing a wiper blade assembly to swing, relative to the wiper arm, between an extended position of the wiper blade assembly and a retracted position of the wiper blade assembly. The power source and driver, which are selectively connected to one another, cause a link, which is attached to the wiper blade assembly, to swing as the wiper arm moves into and out of the hidden park position. A first embodiment uses a pressure fluid source as the power source and a piston as the driver to cause pivotal movement of the link as the wiper blade assembly moves into and out of the hidden park position. A second embodiment uses an electrical source as the power source and an electrical motor as the driver to cause pivotal movement of the link as the wiper blade assembly moves into and out of the hidden park position.

摘要： A unitized cowl and wiper arm assembly includes a blow molded plastic shell structure and two wiper arms of the integral type. At two locations, the shell is reformed so as to create an area of increased stiffness that includes a pair of spaced, overhanging interior flanges. This allows the journal portion of the arms to pass through the shell and be pivoted thereto between the spaced interior flanges. Thereafter, the arm is rigidly and securely supported. The leakproof interior of the shell may also be used for a fluid reservoir.

摘要： A feedback control circuit limits current being supplied to an electric drive motor. The motor drives a load cyclically along a path, and the load closes a switch when it passes a predetermined position. This activates a timing circuit which times out after a predetermined delay. If the load does not return to the predetermined position at the end of the prescribed delay time, then an oscillator circuit is triggered into operation to periodically terminate current flow to the motor. This provides cooling periods and enables the motor to exert repeated, temporary high torque efforts to restore normal operation.

摘要： An adjustment mechanism uniquely tailored to a space crank wiper system is used to adjust the wipe angle, specifically to lower the inwipe to give a depressed park position. The characteristic spacing of a four bar spatial mechanism that drives the wiper post is shortened by a jack screw mechanism that shifts an input crank closer to the wiper post. This lowers the inwipe position. A worm wheel selectively holds or turns the jackscrew, which axially moves a splined stub shaft in the end of a drive shaft to move the crank back and forth.

摘要： A check valve, for use in a vacuum accumulator. The check valve includes a movable gate, which blocks fluid flow. The gate carries a first electrical contact, which mates with a second electrical contact, when the gate closes, thereby issuing a signal which indicates closure. The invention eliminates the need for a separate pressure sensor, for sensing pressure within the accumulator.

摘要： A windshield wiper system for automotive vehicles includes a rack and pinion arrangement in the wiper arm for causing movement of a wiper blade assembly relative to the wiper arm between an extended position of the wiper blade assembly and a retracted position of the wiper blade assembly. More specifically, the rack and pinion arrangement causes a link, which is attached to the wiper blade assembly, to swing such that the wiper blade moves between the extended position and the retracted position. The movement of the wiper blade assembly into the extended position increases the amount of the surface area of the windshield which is wiped. A planetary gear arrangement is driven by a standard wiper drive and selectively drives the rack and pinion arrangement to move the wiper blade assembly between the extended and retracted positions.

摘要： This invention relates to windshield wiper system and method which utilizes a flexible member to account for compression loads in excess of a predetermined load, such as 30 percent greater than a maximum load for the flexible member. The system utilizes a flexible pultruded composite material having a relatively low modulus of elasticity, yet relatively high elongation characteristics. The flexible arm bends to facilitate preventing damage to components in the wiper system when a compressive load applied to the flexible member reaches a predetermined load as a result of a fatigue condition, such as snow or ice build up on the windshield.
