Second Impact (safety)
The second impact (also known as ''second collision'' and ''human collision'') is the impact suffered between a vehicle occupant and the vehicle during a collision. The first impact is the impact between the vehicle and another object. There is also a third impact between the internal organs and the frame of the body. The term was coined in the 1950s by Sergeant Elmer Paul of the Indiana State Police. Paul convinced Indiana authorities to investigate the mechanics of highway injuries, and worked with safety pioneer Hugh DeHaven. The effects of the second impact are reduced by the use of seat belts, airbag An airbag is a vehicle occupant-restraint system using a bag designed to inflate extremely quickly, then quickly deflate during a collision. It consists of the airbag cushion, a flexible fabric bag, an inflation module, and an impact sensor. T ...s, interior vehicle padding and removing of aggressive structures.

Indiana State Police
The Indiana State Police is the statewide law enforcement agency for the U.S. state of Indiana. Indiana was the 12th state to offer protection to its citizens with a state police force. Its headquarters are in the Indiana Government Center North in Indianapolis. History On July 15, 1921, the Indiana legislature, with approval from the governor, to appoint "all necessary deputies in addition to the present officers of the law" to enforce a newly enacted vehicle registration law. The secretary of state appointed a 16-man ''Indiana Motor Vehicle Police,'' becoming the first law enforcement agency in the state to have statewide jurisdiction to enforce traffic laws, although they had only "limited" authority and were only authorized to enforce the "rules of the road" and motor vehicle laws. On March 10, 1927, the Indiana legislature created a ''Bureau of Criminal Identification and Investigation'', also under the secretary of state, for the purpose of installing and maintaining " ...

Hugh DeHaven
Hugh DeHaven (3 March 1895 – 13 February 1980) was an American pilot, engineer and passive safety pioneer. DeHaven survived a plane crash while training as a Royal Canadian Flying Corps pilot during the First World War, and became interested in improving human survivability in vehicle crashes. He has been called "Father of Crash Survivability". Early life DeHaven was born in 1895 in Brooklyn, New York. His father was a steel worker and inventor. He attended Fessenden School in West Newton, Massachusetts from 1906 to 1909 before attending The Hill School in Pottstown, Pennsylvania from 1909 to 1914. Following graduation DeHaven attended Cornell University from 1914 to 1915, and Columbia University from 1915 to 1916. He tried to join the US Army Air Corps in 1916, but was rejected. He joined the Royal Flying Corps Canada in Toronto, Ontario, Canada. While training as a pilot during the First World War, DeHaven survived a plane crash.

Seat Belt
A seat belt (also known as a safety belt, or spelled seatbelt) is a vehicle safety device designed to secure the driver or a passenger of a vehicle against harmful movement that may result during a collision or a sudden stop. A seat belt reduces the likelihood of death or serious injury in a traffic collision by reducing the force of secondary impacts with interior strike hazards, by keeping occupants positioned correctly for maximum effectiveness of the airbag (if equipped), and by preventing occupants being ejected from the vehicle in a crash or if the vehicle rolls over. When in motion, the driver and passengers are traveling at the same speed as the vehicle. If the vehicle suddenly stops or crashes, the occupants continue at the same speed the vehicle was going before it stopped. A seatbelt applies an opposing force to the driver and passengers to prevent them from falling out or making contact with the interior of the car (especially preventing contact with, or goin ...

Airbag
An airbag is a vehicle occupant-restraint system using a bag designed to inflate extremely quickly, then quickly deflate during a collision. It consists of the airbag cushion, a flexible fabric bag, an inflation module, and an impact sensor. The purpose of the airbag is to provide a vehicle occupant with soft cushioning and restraint during a collision. It can reduce injuries between the flailing occupant and the interior of the vehicle. The airbag provides an energy-absorbing surface between the vehicle's occupants and a steering wheel, instrument panel, body pillar, headliner, and windshield. Modern vehicles may contain up to 10 airbag modules in various configurations, including: driver, passenger, side-curtain, seat-mounted, door-mounted, B and C-pillar mounted side-impact, knee bolster, inflatable seat belt, and pedestrian airbag modules. During a crash, the vehicle's crash sensors provide crucial information to the airbag electronic controller unit (ECU), including coll ...
