A windshield wiper system (3) for a windshield (1) having a curved surface and an oscillating gear drive (2) with a central park position (A). Said system (3) comprises at least one wiper arm (13) and wiper blades (5), said wiper blades (5) being mounted by means of said at least one wiper arm (13) to said oscillating gear drive (2). The windshield (1) and the wiper blade lips (11) have a frictional coefficient (μ). Two wiper arms (13), two wiper blades (5) each with a fit bolt (20), bearing bushes (10), a prolongation fitting (7) and a rocker (6) are provided. Said two wiper blades (5) are mounted rotatable about a wiper blade rotation axis (9), perpendicular to said oscillatory axis (V) and said longitudinal axis (U). Said wiper blade rotation axis (9) is defined by a center line through the fit bolts (20) mounted opposed to each other on said two wiper blades (5) being essentially parallel with a distance (a) to each other. Said rocker (6) rotatable attaches each of the two wiper blades (5) by means of the fit bolt (12). The prolongation fitting (7) rotatable attaches the rocker (6) to the wiper arms (13). The fit bolt (12) with the rocker (6) defines a rocker rotation axis (8) in a plane defined by said oscillatory axis (V) and said longitudinal axis (U) with an inclination angle β to the outer surface of the windshield (1) in the central park position (A) providing a distance (b) direct under the wiper blades rotation axis (9) between the windshield (1) and the rocker rotation axis (8) perpendicular to the windshield (1) in the central park position (A) fulfilling [ 2 · b a ]
