ABSTRACT:
A vehicle window wiper system has wipers with a range of motion between an in-wipe position I and an out-wipe position O when the wiper system is in a run mode, and a variable park range for the wipers between the in-wipe position I and a depressed park position P when the system is in a park mode. The wiper system has a reversible motor 40 for rotating a shaft 42 in a first direction when in the run mode and through a first predetermined arc in a counter direction when in the park mode. A clutch mechanism 38 mechanically connected with the shaft 42 has interconnected gears 62, 100, 112 and plates 46, 86 for varying the oscillatory wipe range of the wipers 12 between the in-wipe position I and the out-wipe position O in response to an obstruction therebetween, for moving the wipers 12 to a depressed park position P when wiper system is turned off, while permitting the wipers 12 to move to a variable intermediate position S between the in-wipe position I and the depressed park position P when prevented from moving to depressed park position P.
