ABSTRACT:
A windscreen wiper includes an elongate curved backbone which is of a resiliently flexible material having a Young's modulus of between 50 to 350 GPa. The backbone has a substantially spatially consolidated cross-sectional profile at substantially all points along its length, and the magnitude of the width at substantially the widest point along the backbone, Wm(expressed in millimeters) is at most (−8.89.10−5*E+0.05378)*L−5.25, where L is the total length of the backbone expressed in millimeters and E is the Young's modulus of the backbone material expressed in GPa. The invention also provides a relationship between the thickness and the length of the backbone.
