Windscreen wiper device with non-circular wiping pattern, in particular for a motor vehicle.

摘要

In a windscreen wiper device enabling at least one wiper arm (6) carrying a wiper blade (5) to be moved by a drive mechanism (8) through an angular travel movement combined with a translational movement of the arm-blade assembly, the drive mechanism consists of a first system of articulated link rods forming a deformable quadrilateral (9) whose deformation is controlled by a second system of articulated link rods forming a deformable pentagon (18) under the action of an operating means (21, 22, 23, 24). Application to motor vehicles in particular. <IMAGE>
