    • A vehicle window wiper assembly has a one-piece carrier with a central section and flexible tips to allow the wiper to accommodate windows of high curvature. The tips have a higher flexibility than the central section, due in part to molded serrations on the bottom surface in combination with decreased thickness and width with respect to the central section. The central section and the tips also have different radii of curvature which provide a uniform pressure distribution across the window during wiping operation, even at high curvature window locations. A blade channel extends the longitudinal length of the carrier for receiving a wiper blade therein. The central section has a molded air foil defined by a downwardly projecting, longitudinally extending lip on a leading edge for preventing wiper assembly lift. The rear edge of the central section may have similar lip. A pair of laterally opposed attachment flanges, as well as laterally opposed stability posts, are integrally molded with the central section, as are the tips and air foil lips. The carrier is integrally molded with the aforementioned features, preferably of a thermoplastic material, with no moving parts, and thus is not susceptible to the adverse effects of snow and ice induced lock-up.
    • 车窗刮水器组件具有一体式载体,其具有中心部分和柔性尖端,以允许刮水器适应高曲率窗口。 尖端具有比中心部分更高的柔性,部分地由于底面上的模制锯齿结合相对于中心部分的厚度和宽度的减小。 中心部分和尖端也具有不同的曲率半径,即使在高曲率窗口位置,也能在擦拭操作期间在整个窗口上提供均匀的压力分布。 叶片通道延伸载体的纵向长度以在其中接收刮水片。 中心部分具有由前缘上的向下突出的纵向延伸的唇缘限定的模制空气箔,用于防止雨刷组件抬升。 中央部分的后边缘可能具有相似的唇缘。 一对横向相对的附接凸缘以及横向相对的稳定柱与中心部分一体地模制,如尖端和气翼唇缘一样。 载体与上述特征,优选热塑性材料整体模制,没有移动部件,因此不易受到雪和冰引起的锁定的不利影响。
