Windscreen wiper with means to regulate the wiping pressure.

摘要

The invention proposes a windscreen wiper device (10) of the type including a windscreen wiper arm (12) mounted so that it is articulated about an axis of articulation (X-X) on a drive head (20) of the windscreen wiper arm, characterised in that it includes a cam (38, 42) connected to the drive head (20) and a cam follower element (44) which is connected to the windscreen wiper arm (12) and which moves along the cam (42) as a function of the relative angular displacements between the windscreen wiper arm (12) and the drive head (20) about the axis of articulation (X-X) in order to apply to the arm a supplementary wiping torque in order to vary the value of the wiping torque. <IMAGE>
