#CMT# #/CMT# The wiper blade, made from an extruded elastomer with supporting (1) and wiping (2) sections separated by an inner cavity (3), has the walls (30) of the cavity made with zones (31) of reduced thickness that allow it to deform and give an optimum angle between the wiping portion and the screen (V). Projections (33) on the cavity's inner surface (32) act as stops to control the geometrical shape of its cross-section during deformation. #CMT#USE : #/CMT# Extruded elastomer wiper blade for vehicle windscreen or similar. #CMT#ADVANTAGE : #/CMT# The design of the wiper blade gives an optimum wiping angle relative to the screen with lower noise level and reduced fatigue. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawings show cross-sections of the wiper blade at rest and in motion.
