    Abstract: A replaceable squeegee assembly or refill unit for a windshield wiper blade incorporates a multi-use backing strip for supporting a rubber-like squeegee element. The backing strip may be integrally formed of molded or extruded plastic material. A pair of squeegee holders, each in the form of a channel-shaped body having inwardly extending opposed flanges at the outer ends of the legs of the channel, are arranged in back-to-back relationship and include a common web portion. A pair of elongate side rails extending longitudinally for the entire length of the channel bodies extending laterally outwardly are provided on the legs of the channel bodies. The side rails associated with each channel body are coplanar; the distance between the longitudinal edges of one pair of side rails is greater than the distance between the longitudinal edges of the other pair of side rails. The differences in the overall lateral width of the pairs of side rails permit use of the backing strip in different superstructures having pairs of opposed claws for slidably receiving the side rails which are spaced apart different distances. The squeegee element may be slidably received in either of the squeegee holders while the side rails on the unused squeegee holder are received between the claws of the superstructure. A clip which interlocks with the backing strip adjacent the end thereof serves to retain the squeegee element within the squeegee holder and also serves to limit the longitudinal displacement of the refill unit relative to the superstructure.

    Abstract translation: 用于挡风玻璃刮水片的可替换的刮板组件或再填充单元包括用于支撑橡胶状刮板元件的多用背衬带。 背衬条可以由模制或挤出的塑料材料整体形成。 在通道的腿的外端具有向内延伸的相对的凸缘的通道形体的形式的一对刮板保持器以背靠背的关系布置，并且包括公共腹板部分。 在通道体的腿部上设置一对纵向延伸用于横向向外延伸的通道体的整个长度的细长侧轨。 与每个通道主体相关的侧轨是共面的; 一对侧轨的纵向边缘之间的距离大于另一对侧轨的纵向边缘之间的距离。 两对侧轨的整个横向宽度的差异允许在具有成对的相对爪的不同上部结构中使用背衬带，以可滑动地接收间隔开不同距离的侧轨。 刮板元件可以可滑动地容纳在任一刮板保持器中，而未使用的刮板保持器上的侧轨被接收在上部结构的爪之间。 与邻近其端部的背衬条互锁的夹具用于将刮板元件保持在刮板保持器内，并且还用于限制再填充单元相对于上部结构的纵向位移。
