Crank assembly for a screen wiper drive of an automotive vehicle

Abstract

A crank mechanism of a driving assembly of a screen wiper for use with an automotive vehicle preferrably a lever and a tongue in communication therewith through a swivel joint, with the tongue are eccentrically hinged to an actuated gear wheel, in particular, a worm gear wheel and with the lever is connected or connectible in a non-rotating way to a wiper shaft. The tongue and the lever, in the practice of the invention, are pivotally interconnected through a bajonet-type connection such that the crank mechanism can be connected without tools. The assembled position enabling tongue and lever to be joined together differs from any possible rotary position taken by these two elements during operation.
