Summary:

This invention solves a significant safety issue where drivers have low visibility of the Outside Rear View Mirror (ORVM) in the case of rain, fog, dust or ice formation on the Side Door Window Glass (SDWG). Currently developed methods, such as hydrophobic finishing or films and heated window glass on the doors, provide temporary or weak results, and thus, a more successful and dependable method is demanded. In order to address this problem, we have modified the Outer Waist Seal, which includes a Glass Wiping Mechanism in it. Outer Waist Seal is a type of weather strip fixed on the bottom of the side window of a vehicle on the panel of the door. It does not allow the flow of heavy water, dust and debris into the door cavity, besides supporting the glass on the window when it is in a movement process. The stationary fixed arm of this system is coupled with a rotating arm and an attached wiper blade powered by a low-speed-high-torque motor and interfaced with the Body Control Module (BCM) of the vehicle. When activated, the rotating arm having a blade will clean or wipeout the dust, water or loose ice particles from the viewing zone or area of an ORVM on the SDWG. The design will have a fixed arm, a rotating arm with a blade, a sliding body, a variable height rib plate (VHRP), a flexible bushing, a Low Speed and High Torque (LSHT) Motor, a base plate, housing which will be attached to the door waist reinforcement panel using fasteners. This system is also successful in eliminating the water droplets, dust, and ice that result in an excellent and consistent visibility of the ORVM in different environments. This promotes confidence in the driver as well as his safety and comfort, and can be used both in passenger and commercial vehicles. The solution is a compact, efficient and robust way of introducing massive change to vehicle safety and drivability and is flexible to accommodate future technologies such as automatic activation when the rain is detected through the sensors, et cetera
