Abstract: The invention relates to a blade for a windshield wiper device and to a corresponding windshield wiper device. The blade comprises a blade body for wiping said windshield surface and a longitudinal rib. The body has a first housing extending longitudinally inside the body and having at least one insertion end. The rib has a cross-section complementary to the cross-section of the first housing. Furthermore, the rib comprises a plurality of interlocking members protruding from its surface by way of a harpoon with an interlocking end. The plurality of interlocking members is oriented such that they allow the insertion of the first end of the rib through the insertion end for assembling the blade, but prevent the extraction of the rib from the first housing.

Abstract: Windscreen wiper device for windscreens with variable curvature, comprising a secondary shaft rotating about its secondary axis between starting and final secondary positions, and a primary shaft on which the wiper blade arm is mounted rotating in an alternating manner about its own primary axis between starting and final primary positions. The primary shaft is mounted in the secondary shaft, such that their corresponding axes form a first acute angle (?) with respect to one another. The device further comprises a delay device kinematically connecting the driving means with the secondary shaft to cause rotation in the secondary shaft such that when the primary shaft has performed 50% of the rotation between the starting primary position and the final primary position, the secondary shaft has performed between 0% and 30% of the rotation between the starting secondary position and said final secondary position.

Abstract: A windshield wiper device for large size curved windshields comprising first and second arms hingedly connected to each other at a distal end by a main spacer and reciprocatingly operable. The device further comprises a windshield wiper blade rockingly mounted relative to said main spacer through rocking means and a secondary spacer mounted on the distal end in redundancy with said main spacer. The rocking means comprise a first toothed member integral with said secondary spacer and a second toothed member integral with said wiper blade, which are mounted meshed with one another to cause the rocking of said wiper blade about time longitudinal axis thereof in the rocking direction opposite to the direction of reciprocating movement of said first and second arms.
