WIPER COMPRISING A SUPPORT ARM WHICH IS PREFERABLY A CINEMATIC PANTOGRAPH, AND A WIPER BRUSH WITH A VARIABLE ATTACK ANGLE

摘要

The invention relates to a wiper comprising: - a drive support (10) intended to be displaced in an alternating rotational movement about a so-called scanning axis (B) which is substantially perpendicular to the surface to be wiped; - an arm (20) rotatably mounted on said drive support, - a wiper blade (30) pivotally mounted relative to the arm (20), - control means (40) controlling the rotation of the arm (20) depending on the angular displacement of the drive carrier (10) and / or controlling the pivoting of the wiper blade (30) as a function of the angular displacement of the drive carrier (10), characterized in that said control means are at least partially carried by a plate intended to be secured to a driving motor shaft and in that the windscreen wiper comprises an arrangement for relative positioning and temporary securing of said drive carrier and the said plateau.
