US Patent 7172233 Motorized extensible wind shield visor

The visor joins to the roof of a motor vehicle to deflect heavy precipitation, such as a downpour, from a windshield. The visor is a permanent motorized device with a hollow planar cover. The cover contains a means to extend and retract the visor from the cover and over the windshield. The extension and retraction means is a spring balanced motorized cable and pulley system. The cable attaches to the rear of the visor and the visor has rollers in tracks for extending and retracting from the cover. A driver presses the switch to extend the visor as the motor unwinds the cable and the springs relax. When a downpour passes, the driver presses the switch to retract the visor as the motorized system reverses. The visor reduces vision impairment of drivers caused by precipitation.
