PREAMBLE OF THE DESCRIPTION
The following specification partcularly describes the invention and the manner in which it is to be performed.

FIELD OF THE NVENTION
The present invention relates to a window wiping system of a vehicle, and more
particularly, the present invention relates to the window wiping system of the
vehicle, which is packaged wihin the door assembly or the body of the vehicle or
he like for wiping window glass of vehicle ke window glass of de doors
ncluding font or rear door
BACKGROUND OF THE NVENTION
The use of wipers is known in the prior art. More specifically, wipers have been used extensively for the front and rear glasses of the vehicle, wherein the wiper assembly is structured on the vehicle, preferably on or near the periphery of the glass screens. Also while driving it is sometimes required to look into the ORVM e. outer rear view mirror, to judge the scope for changing ane or take any specific direction by ascertaining that no vehicle is coming from either side of the vehicle. However, durng certain conditions lke rain or fog situation, it becomes very difficult to ook nto the ORVM and o identify whether it is safe to change ane or take any specific directions due to foggy door glasses. Therefore, it results in unsafe siuation for the driver to make proper judgement, thereby resulting in accidents. In order to provide proper vision hrough ORVMs durng rainy or foggy situations, a wiper assembly can be positioned on or at the periphery of the window glass of the sde doors. However, due to smaller size of the window glass and the side door, such positioning would result in protruding or extending vehicle breadth across its horizontal axis and also would decrease he vion hrough window glass due its smaller sze.
US Patent No. US5410774A discloses a portable vehicle window wiper which includes a housing having a bracket projecting therefrom, which is inserted between a base of the window and he adjoining portion of the vehicle door A

wiper blade is pivotally mounted to the wiper arm for effective cleaning of the window. The housing also includes a motor which is powered through a power chord. The power cord can receive power from the vehicle. Though the US documents provides a solution of using a portable vehicle window wiper, but since it is installed on the outer side of the door, it will result in increasing overall vehicle width, which can alter the vision area through ORVM. Further, since it is hooked between the window and the adjacent portion of the vehicle, it may get unhooked while at higher speed or when the window is opened or closed. Furthermore, the structure requires power supply from an external source by means of a power of cord, in such case, it will be necessary to keep window slightly open to accommodate he power cord, which would again esult in a compromie wih the noise fom outde.
Therefore, the problem to be solved s to provide a wiping system that efficiently cleans the window of the side doors to overcome the impaired vision due to foggy window glasses during rain and to provide a proper vision ORVM (Outer Rear View Mirror) during rain, and can be packaged within the door assembly without increasing the overall width of the vehicle, and the problem is solved in the present invention by the window wiping system of a vehicle, which includes a wiping assembly comprising of a wiper arm and a wiper blade pivotally connected with the wiper arm, the wiper assembly is mounted on the inner door assembly of the side door, such that the actuating assembly extends and retracts he wiper assembly fom within the inner door assembly, wihout increasing the width of the vehicle.
