CRANK MECHANISM FOR A WINDSCREEN WIPER DRIVE OF A MOTOR VEHICLE

摘要

In a crank mechanism for a windscreen wiper drive for a motor vehicle which consists of a lever (10) and a shackle connected thereto via an articulated joint (11) in which said shackle is articulated eccentrically on a driven gear wheel, especially a worm wheel (4) of the drive, and the lever (10) is or can be connected integrally in rotation to a wiper spindle (12), the shackle (8) and the lever (10) are articulatedly interconnected according to the invention via a bayonet-like joint (13) so that the crank mechanism can be dismantled without the need for tools. The fitting position which permits the connection of the shackle (8) and the lever (10) differs from any possible rotation position which these two components may assume during operation.
