The patent though doesn’t mention anything about the size of the glass breaker, though it does state the L-shaped design.
According to a media report, Ford has filed a patent for a new sun visor design for their cars, which doubles up as a tool to break the car’s glass windows during an emergency.
As seen from the patent images, the sun visor looks like any conventional found in all vehicles. It comes mounted on a metal rod which flips as required to block the sun. However, instead of being permanently mounted, the sun visor can be removed from the metal rod to reveal a sharp end. The rod can further be removed from the roof mount, which can, in theory, shatter a window in case of an emergency.
The patent though doesn’t mention anything about the size of the glass breaker, though it does state the L-shaped design. Also, the patent doesn’t mention safety protocols for accidentally breaking windows, considering it is positioned so close to the windscreen.
The patent by Ford seems simple and a no-brainer, however, whether or not the carmaker will actually bring it to production vehicles is yet to be seen.
