A windshield wiper blade for a vehicle windshield wiper device features a wiper blade rubber made of a resiliently deformable material which exhibits a backing to which two parallel wiper lips are connected by means of a flexible neck and an intensive-cleaning element attached to each of the mutually remote longitudinal sides of the wiper lips, wherein the intensive-cleaning element leading relative to the direction of motion of the wiper blade rubber and the wiping edge of the trailing wiper lip contacts the windshield. In order to improve the wiping quality of the wiper blade rubber, both wiper lips exhibit an essentially triangular cross-section of standard wiper blade rubbers and are connected to the backing in such a way that, when the wiper is operating, each can be supported on the bottom side of the backing with a shoulder lying at the rear in relation to the direction of motion. In another variant designed to improve the wiping quality of the wiper blade rubber, the intensive-cleaning elements are formed by numerous individual segments mutually spaced along the length of the wiper blade rubber, with the segments of one intensive-cleaning element offset in the longitudinal …
