WINDOW WIPING DEVICE WITH PANTOGRAPH KINEMATICS AND A VARIABLE ANGLE OF ATTACK

摘要

The invention relates to a window wiping device (100) with pantograph kinematics and a variable attack angle, said device comprising: a drive carrier (110) to be driven in an alternating axially rotating manner; a rotary arm (120) which is mounted in a mobile manner in such a way as to axially rotate in relation to the drive carrier (110); first means (130) for controlling the axial rotation of the rotary arm (120); a rotatable head (140) mounted in a pivoting manner on the distal end of the rotary arm (120) and used to support a wiper blade (1); and second means for controlling (150) the pivoting of the rotatable head (140). The invention is characterised in that the second control means (150) can convert the axial rotary motion of the rotary arm (120) into a linear motion, and transmit the same to the rotatable head (140), said linear motion being able to pivot the rotatable head (140).
