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 (β) 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.
