摘要： A windshield wiper system in which a flexible cantilever arm to which a wiper blade is attached is preloaded against a rigid support. An additional preload is induced in the cantilever arm as the wiper system is installed on a vehicle with the wiper blade in the horizontal inwipe position and bearing against the windshield. This creates an initial separation between the cantilever arm and the rigid support. As the rigid support and the cantilever arm move together from the horizontal inwipe position to the vertical outwipe position, the separation between the rigid support and the cantilever arm decreases, so that, with the increased contact between the rigid support and the cantilever arm, there is a change in the cantilever arm support location and a shortening of the cantilever arm beam. Conversely, as the rigid support and the cantilever arm move together from the vertical outwipe position to the horizontal inwipe position, the separation between the rigid support and the cantilever arm increases, so that, with the decreased contact between the rigid support and the cantilever arm, there is a change in the cantilever arm support location and a lengthening the cantilever arm beam. In this way, the contact and pressure between wiper blade and the windshield being cleaned is maintained constant or substantially constant as the wiper blade sweeps across the windshield.

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.

摘要翻译： 用于机动车辆的挡风玻璃刮水器系统包括电源和驱动器，用于使刮水片组件相对于刮水器臂在雨刮器组件的延伸位置和刮水片组件的缩回位置之间摆动。 电源和驱动器被选择性地彼此连接，使得连接到刮水片组件上的连杆随着刮水器臂移入和移出隐藏的停放位置而摆动。 第一实施例使用压力流体源作为动力源，而作为驱动器的活塞作为刮水片组件移入和移出隐藏的停放位置时引起连杆的枢转运动。 第二实施例使用电源作为电源，并且电动机作为驱动器，当刮水片组件移入和移出隐藏的停放位置时，引起连杆的枢转运动。
