Early work
Hugh Robertson Dehaven was an inventor of long standing. Between 1924 and 1933 DeHaven filed seven patent applications related to his design of a self-sharpening single edge safety razor. Between approximately 1930 and 1936 his De Haven Razor Corporation marketed a number of different models based upon these designs. DeHaven himself retired in 1933.
DeHaven was issued in 1955 for the first three-point seat belt.
Early in the 20th century, DeHaven established the ''Aviation Safety and Research Facility'' at Cornell University

s and seat belts at a 45° angle in airplanes. He created the inertial reel and the concept of the "delethalized" instrument panel.
Crash Injury Research (CIR)
In 1942, DeHaven started the Crash Injury Research project at Cornell, and published the classic ''Mechanical analysis of survival in falls from heights of fifty to one hundred and fifty feet''. He concluded:
::''The human body can tolerate and expend a force of two hundred times the force of gravity for brief intervals during which the force acts in transverse relation to the long axis of the body. It is reasonable to assume that structural provisions to reduce impact and distribute pressure can enhance survival and modify injury within wide limits in aircraft and automobile accidents.''
In 1950, DeHaven published a report pointing to the second collision and the risk involved in vehicle ejection. He created the concept of "packaging" car occupants. He concluded:[Hugh DeHaven - Still Relevant for Rollovers](_blank)

Quotes
::''We will get into anybody’s automobile, go any desired distance at dangerous speeds, without safety belts, without shoulder harness, and with a very minimum of padding or other protection to prevent our heads and bodies from smashing against the inside of a car in an accident. The level of safety which we accept for ourselves, our wives and our children is, therefore, on a par with shipping fragile valuable objects loose inside a container.''
::''"...people knew more about protecting eggs in transit than they did about protecting human heads"''
