WINDSHIELD WIPER MECHANISM

摘要

A cowl mounted windshield wiper transmission assembly and power unit is pre-assembled as unit. It includes a rigid guide track having a housing secured thereto at each end and a transversely flexible tape slidable in the guide track. Each housing encloses a cam element to which an end of the flexible tape is secured. A pivot shaft for receiving a windshield wiper arm extends axially from the housing. The output of a power unit is coupled to the tape to cause oscillating linear movement of the tape thus resulting in oscillating motion of the pivot shafts and wiper arms.
