Abstract: A wiper with rise-up mechanism includes a crank and a rod that is rotatably connected to the crank through a shift mechanism. The crank supports an eccentric rotor. The rod is coupled to the eccentric rotor to rotate about the axis of the eccentric rotor. A key is supported in the eccentric rotor to move axially. The key can be moved by the rotation of the crank. When the crank rotates in a normal direction, the key locks the eccentric rotor to the rod. When the crank rotates in the reverse direction, the key fixes the eccentric rotor to the crank. Only one key is used, which reduces the number of parts and simplifies the operation of the key.

Abstract: A window wiper system for an automotive vehicle has an electromagnetic device, a rotatable member and a window wiper oscillating mechanism. In another aspect of the present invention, the electromagnetic device is an electric motor which operates in a unidirectional manner to oscillate a window wiper assembly back and forth in a normal window wiping range. The electric motor and rotatable member then reverse rotational direction to move the wiper assembly to a park position offset from the normal window wiping range.

Abstract: In a drive mechanism for a windshield wiper, a switch disk for realizing a park position switch is supported so as to be independently rotatable relative to an output gear of a gear unit. The output gear and the switch disk are coupled with each other via a coupling device, with the coupling device acting as an engaging device carrying the switch disk along, in one direction of rotation only. In order to lower an axial dimension of the gear unit, the disk is rotatably supported on a sleeve, through which an output shaft extends so that the end of the shaft can support itself directly on a housing lid.
