摘要

The windscreen wiper assembly has two wiper arms (12) driven by a rotating shaft (18). A drive head (14) is fixed to the upper end (16) of the rotating shaft, and a drive crank (20) moves the rotating shaft. The drive head and wiper arm have complementary indexing features (46,48). The indexing features are arranged differently for each of the two wiper arms to prevent them from being mounted in the wrong position on the vehicle.
