Windscreen wiper and deflector therefor
First Claim
1. A deflector apparatus for use on a windshield wiper having a blade and carried by a wiper arm, said apparatus comprising:
- a longitudinal deflector member having a convex deflector surface to be directed toward a windshield surface to be wiped;
hooking means, connected to said deflector member, for mounting said deflector member on one of the wiper or the wiper arm in a position such that said deflector surface is spaced from the windshield surface to be wiped;
said deflector member having a first edge spaced from said hooking means and a second edge adjacent said hooking means;
said deflector surface having the shape of a convex dihedron and including a substantially flat first portion extending from said first edge toward said second edge and a substantially flat second portion intersecting said first portion and extending therefrom to said second edge, said first and second surface portions being continuous surfaces along the entire length of said deflector; and
said first surface portion being inclined at a first angle relative to the median plane of the windshield surface to be wiped, when said deflector member is mounted in said position, and said second surface portion being inclined at a second angle, relative to such median plane when said deflector member is in said position, said second angle being greater than said first angle.

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.
