John W. Hetrick of Newport, Pennsylvania was an inventor who patented a safety cushion assembly for automobiles in 1953. His patent describes inflatable cushions kept deflated in the passenger compartment that fill from an air reservoir when the vehicle slows suddenly in a collision or hard braking, giving a passenger a yielding surface to meet. A normally closed valve between the reservoir and the cushions opens instantly when the sudden slowing is sensed, with the aim of preventing death and injury.
