ABSTRACT:
A wiper deicing device for a vehicle is disclosed which comprises a mechanism for resiliently impacting the window wiper against the window, including a reciprocatable member operatively engagable with the wiper, and a mechanism for stabilizing movement of the reciprocatable member. The impacting means includes either a manual or powered actuator for cyclically moving the reciprocatable member between extreme positions thereof, corresponding to a position in which the wiper is engaged with the window and a position in which the wiper is disengaged from the window, and will preferably include one of a cam mechanism, a gear mechanism, a crank mechanism and a lever mechanism operatively connected to or engaged with the reciprocatable member. The deicing device also preferably includes a mechanism for limiting pivoting movements of a blade portion of the wiper relative to an arm portion of the wiper for thereby distributing a lifting force of the reciprocatable member across a length of the wiper blade.
