| 摘要 |
<p>The invention concerns a wiper arm (10) comprising a body extending longitudinally from is rear driving end (12) towards its front end (14) 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 (18, 20) mutually connected by an upper back (22) and extending towards the surface to be wiped, consisting of a downstream wing (18) remaining substantially perpendicular to the back (22) and an inclined upstream wing (20) forming an acute angle (A) relative to a median plane (V) parallel to the downstream wing (18) to form an aerodynamic deflector integrated in the wiper arm which, by the action of a relative downwind direction (F), tends to urge the wiper arm (10) towards the surface to be wiped. The upstream wing (20) has a substantially planar or curved surface and the value of said angle (A) ranges between 30° and 45°.</p> |
