A curved elongate backbone for a windscreen wiper has a loading profile that increases substantially from a central connector towards one or both ends of the backbone. The second differential of the bending moment also increases substantially from the connector towards the ends. The loading may increase right to the ends of the backbone or the backbone may have end portions with constant loading. In order to obtain the desired loading profile the width, thickness and free-form radius of curvature are suitably selected. In preferred embodiments, the backbone has a rectangular cross-sectional profile and the thickness and width decrease uniformly from the connector to the ends. However the thickness may also be constant for end portions.
