ABSTRACT:
A motor vehicle screen wiper apparatus comprises a screen wiper mounted on the upper end of a drive spindle, the apparatus including means for varying the inclination between the spindle axis and a reference axis which is substantially at right angles to the plane of the glass to be swept. The drive spindle is mounted for pivoting movement about at least one pivot axis, and the apparatus includes a cam mechanism which controls this pivoting movement of the drive spindle, so as to vary the inclination between the drive spindle axis and the reference axis as a function of the rotational position of the drive spindle about its own axis of rotation.
