Abstract
An anti-lift deflector for a windscreen wiper includes a hooking member for mounting the deflector onto a wiper or wiper arm and an aerodynamic blade attached to the hooking member and having a substantially flat first zone extending rearwardly from a leading edge of the blade followed by a second zone which is inclined relative to the first zone and which terminates at a trailing edge of the blade. During use of the deflector, the first zone is slightly inclined relative to the surface to be wiped and the second zone is inclined relative to the surface to be wiped at an angle greater than the first zone. This creates a surface effect giving a relatively large pressure decrease below the deflector, thus forcing the wiper blade into contact with the surface to be wiped.
