The windscreen wiper device includes the oscillating arm which consists of two end pieces (3,4) jointed to the extremities of an intermediate piece (2). The wipers (5,6) are mounted on the intermediate and outer pieces (2,4) and the arm executes alternating circular movements under the control of a motor coupled to the inner piece (3).Pressure (P) is applied to the windscreen from two springs (10,11) acting across the respective joints. The wipers themselves are conventional with a single blade (20) in a mounting (18) hinged to the arm.
