Stopper device for windscreen wiper's brush holding arm of motor vehicle, has stop blocking element's pivotment when gap attains reduced angle and element is subjected to torque lower than value, and deactivated when torque exceeds value

摘要

#CMT# #/CMT# The device (100) has a movable element (20) pivotingly mounted with respect to a support element (10) and coupled to a wiping brush. A U-shaped elastically deformable fusible stop (110) blocks a pivotment of the element (20) when a gap between the elements attains a reduced angle and when the element (20) is subjected to a turning torque that is lower than a predetermined threshold value, where the stop is of accordion shape. The stop is deactivated when the turning torque applied to the element (20) exceeds the threshold value. #CMT#USE : #/CMT# Stopper device for reducing mobility and protecting integrity of a brush-holding arm, of a windscreen wiper of a motor vehicle (claimed), with reduced disengagement. #CMT#ADVANTAGE : #/CMT# The configuration of the device permits to reduce angular displacement between the movable and the support elements of a brush holding arm when the arm is disengaged in normal usage conditions and to indicate a user that the arm is subjected to disengagement with excess amplitude, while guaranteeing integrity of the arm with reduced disengagement. The movable element is coupled to the wiping brush for ensuring clarity. The fusible stop permits to use a standard brush holding arm that is converted into the arm with reduced disengagement, in an easy, rapid and inexpensive manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a brush-holding arm in a disengaged position with excessive amplitude. 10 : Support element 20 : Movable element 100 : Stopper device 110 : U-shaped elastically deformable fusible stop 111, 112 : Lateral grooves.
