The present model 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.
