CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY
[001] The present application does not claim priority from any patent application.
TECHNICAL FIELD
[002] The present disclosure in general relates to the field of automobile. More particularly, the present subject matter relates to a system and a method for blocking sun glare on a windshield of an automobile.
BACKGROUND
[003] Driving a car with sun glaring into windshield glass could be quite challenging as glare blocks the driver’s view of road. A sun visor is a component of an automobile located on the interior just above the windshield utilized to block sun glare conventionally. Most modern cars have two conventional sun visors, one for the driver's side and a second for the passenger's side, with the rear-view mirror often mounted in between the two sun visors. Each sun visor can be lowered to help block light from the sun entering through the windshield. Some are designed so they can be released from one bracket and be turned towards the side window, covering a small part of the window at the top to block sunlight shining onto the side of the face.
[004] Generally, the conventional sun visors are static fixed held devices and cannot be moved based on incident sunrays. Thus, the conventional sun visors fail to block the sun glare when the position of sunrays changes as the car navigates the road, where in one moment the sunrays appear directly in front of driver’s eyesight and next moment it disappears after a turn or going downhill. Accordingly, the conventional sun visors fail to provide a mechanism to block sunrays irrespective of contours of road.
