Abstract: The invention concerns a wiper arm comprising a body extending longitudinally from its rear driving end towards its front end which bears a wiper blade, and wherein, in cross section, at least a section of the arm body has an upturned U-shaped cross section defined by two wings mutually connected by an upper back and extending towards the surface to be wiped, consisting of a downstream wing remaining substantially perpendicular to the back and an inclined upstream wing forming an acute angle relative to a median plane parallel to the downstream wing to form an aerodynamic deflector integrated in the wiper arm which, by the action of a relative downwind direction, tends to urges the wiper arm towards the surface to be wiped. The upstream wing has a substantially planar or curved surface and the value of said angle ranges between 30° and 45°.

Abstract: A windshield wiper, in which an element of the frame of the wiper blade is articulated on the end of a wiper arm by a connector that is articulated on the frame. The connector includes a substantially inverted U-shaped front body which overlaps onto the center part of the hinge of the frame, such that the longitudinally sliding connector is accommodated in the front end of the arm. The connector includes a lock mechanism that locks in a longitudinally direction in relation to the arm. The connector also includes a retaining rod extending vertically with clearance through a hole that is dead center with the center part of the hinge of the frame element.
