摘要

The windscreen wiper blade carries a cleaning scraper (10), mounted on a rigid profile (30), generally flat in shape, to form an aerodynamic deflector. The lower part of the rigid profile, nearer the glass, carries a continuous roll section (42), which consists of an upper claw section (44) for mounting to the rigid profile and a lower slimmer part (46), in the form of a lip, which may contact the windscreen. The roll section is produced by extrusion of two materials, of which one (M1) is rigid, or semi-rigid, and the other (M2) is flexible.
