ABSTRACT:
A screen wiper for a motor vehicle windshield comprises a screen wiper arm which is articulated about an articulation axis (X--X) on a drive head for driving the wiper arm. The wiper includes a cam connected to the drive head and a cam follower element which is connected to the screen wiper arm and which is displaced along the cam profile as a function of the relative angular displacements between the wiper arm and the drive head about the articulation axis (X--X), so as to apply to the arm a complementary torque such as to cause the value of the wiping torque to vary.
