    Abstract: A windshield wiper blade includes a pressure-distributing frame having a series of levers arranged in partially overlapping relationship flexibly connected together; a lower articulating frame member retained by claws disposed at the free ends of adjacent lever members retains a rubber flexible blade interlocked with a blade-receiving seat in the lower frame member. Primarily for cold weather use the frame is enclosed by a rubber weather-protecting hood interlocked with the lower frame member and the rubber blade. An arm-attaching element is secured to the upper side. The lever members are connected together with a plastic or other nonmetallic substantially cylindrically shaped connector; the connector includes annular grooves adjacent each end which form a head at each end and a spacing flange intermediate the ends. The annular groove at one end of the connector is received in a keyhole slot adjacent an end of the lever. The annular groove at the other end is slidably received in a keyhole slot formed intermediate the ends of an adjacent lever, the levers thus being spaced apart at their points of connection by the intermediate flange of the connector element.

    Abstract translation: 挡风玻璃刮水片包括:压力分配框架,其具有以部分重叠关系布置的一系列杆,弹性地连接在一起; 由设置在相邻杆构件的自由端的爪保持的下铰接框架构件保持与下框架构件中的刀片接收座联锁的橡胶柔性刀片。 主要用于寒冷天气,框架由与下框架构件和橡胶叶片联锁的橡胶防护罩围住。 臂附接元件固定在上侧。 杠杆构件与塑料或其他非金属基本上圆柱形的连接器连接在一起; 连接器包括邻近每个端部的环形槽,其在每个端部处形成头部,在端部之间形成间隔凸缘。 连接器一端的环形槽被容纳在与杠杆的端部相邻的锁眼槽中。 在另一端的环形槽被可滑动地容纳在形成在相邻杆的端部之间的锁眼槽中,杠杆因此在连接点处通过连接器元件的中间凸缘间隔开。
