摘要

Scraper blade (20) is carried by a support structure (36) belonging to the wiper blade (28). Scraper blade whose lower part is in a rigid material is mounted to move relative to the support in a direction perpendicular to the wiping direction and to the blade longitudinal direction between a top retracted position and a bottom cleaning position. Hydraulic control actuator (40) displaces the scraper blade between its top and bottom positions.
