Extendable windshield wiper system

An extendable windshield wiper system includes a wiper blade assembly having a resilient material wiper blade; and a wiper extension rod connected to the wiper blade. A wiper sleeve is configured to move about an arc of rotation with respect to an axis of rotation of the wiper sleeve. A bore of the wiper sleeve has the wiper extension rod slidably disposed within the bore. An actuation portion directs a pressurized fluid to outwardly extend the wiper extension rod from the wiper sleeve and thereby to outwardly extend the wiper blade in an extension direction during a first portion of the arc of rotation. The wiper blade is induced to traverse an extended arc of travel during rotation of the wiper extension rod and the wiper sleeve along the arc of rotation. 一种可延伸的挡风玻璃雨刮器系统包括雨刮器片组件，该雨刮器片组件具有弹性材料雨刮器片和连接到雨刮器片的雨刮器延伸杆。雨刮器套筒配置成相对于雨刮器套筒的旋转轴线绕旋转弧运动。雨刮器套筒的孔具有可滑动地设置在所述孔内的雨刮器延伸杆。致动部分引导加压流体在旋转弧的第一部分从雨刮器套筒向外延伸雨刮器延伸杆，从而在延伸方向上向外延伸雨刮器片。在雨刮器延伸杆和雨刮器套筒沿旋转弧旋转的过程中，雨刮器片被引导横穿延伸的行进弧。
