Title:
【発明の名称】空力学的デフレクタの形状を有するワイパーアーム
Document Type and Number:
Japanese Patent JP2002528324
Kind Code:
A
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°.
