US Patent 7234825 Curved rearview system for vehicles

The curved rearview mirror system for vehicles allows a driver to see the entire area of a driver's blind spot from looking into any one of three mirrors without giving the driver an overly distorted view. The mirror system includes a central rearview mirror with a central planar section and two side convexly curved sections having a constant radius of curvature. The mirror system also includes left and right side rearview mirrors. Each side rearview mirror includes a central planar section, a convexly curved side section, a convexly curved top section, and a convexly curved bottom section. The shape and placement of each mirror is governed by a series of equations that give the driver the best possible view of the blind spot.
