#CMT# #/CMT# The mechanism has a rotary support (30) supporting, in axial rotation, middle and outlet sprockets (50, 60), and a fixed sprocket (40) coaxially positioned with respect to a primary axle (20). An actuating arm (80) has an end (81) integrated with a secondary axle (70) and another end (82) fixedly coupled, by a fixation point (83), with a detachable part displaced along an elliptical sweeping movement. A ratio between a distance separating the secondary axle and the point and a center distance separating the axles is comprised between 0.98 and 1.18. #CMT#USE : #/CMT# Used in a wiping device implanted at a lower part of a rear window and a front windscreen of a motor vehicle (claimed) e.g. car. #CMT#ADVANTAGE : #/CMT# The ratio between the distance separating the secondary axle and the fixation point and the center distance separating the axles ensures a displacement of the fixation point in a straight line when the actuating arm is activated, so that the arrangement of the mechanism at the interior of the vehicle requires only a simple cutting, such as a slit, in the form of a line segment, thus reducing a support surface required by the cutting, and hence ensuring an easy integration of the mechanism in the motor vehicle body. The cutting in the form of the line segment is aesthetic and can be easily sealed so as to avoid the introduction of objects or fingers into the slit, thus avoiding the risk of injury to users and the risk of degradation of the mechanism while preserving the mechanism from bad weather and soiling. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional top view of a wiping device. 1 : Wiping device 10 : Driving mechanism 20 : Primary axle 30 : Rotary support 40 : Fixed sprocket 50 : Middle sprocket 60 : Outlet sprocket 70 : Secondary axle 80 : Actuating arm 81, 82 : Actuating arm`s ends 83 : Fixation point 102 : Slit. |
