On November 10, 1970, Samuel Young received U.S. Patent No. 3,538,508 on a Combination pillow and Crash Helmet:

The patent explains that the device “is useful as a courtesy pillow for the comfort of airline passengers, and doubles as a crash helmet which may be put over the head of the passenger when he is forewarned of an impending crash landing.”

The pillow never caught on, but one can imagine the eerie sight the FAA and NTSB would encounter investigating a crash and finding all these bodies with their heads in a cloth envelope.
