The patent showcases several images of a conventional-looking sun visor, the kind you’d find in any vehicle. Mounted on a metal rod, it offers the flexibility to be flipped as needed to shield against the sun’s rays. However, what sets this sun visor apart is its ability to be detached, revealing a pointed end, referred to as the “impact point” in the patent’s documentation. Furthermore, the rod can also be removed from its roof-mounted bracket, transforming into a handy tool capable of breaking windows. It’s an ingeniously simple concept.
