| 摘要 |
The present invention refers to an arrangement introduced In a blade, secured to an arm (2) of the wiper, wherein said blade (1) acts on the surface of a windshield (3), said blade (1) having a blade body (6) formed as a single piece by welding, bonding, fitting or coextrusion of two different profiled materials, resulting in a single body having a curved shape throughout its length to allow uniform distribution of the load applied by the arm (2) of the wiper. The blade (1) and the arm (2) are joined together by a sequential central support (10), made of metallic or plastic material, or, alternatively, by an enclosing central support (11), joining the blade body (6) through a metal vertebra (7). The blade body (6) has alternative constructive arrangements in its upper region, having a symmetric (16) or asymmetric (21) spoiler, as well as an alternative constructive arrangement with no spoiler at all, but only a convex bulging (26), leading to improved distribution of the airflow on the blade. |
