A Seat Belt reduces severity of injuries and chances of death in a serious car accident by reducing the secondary impact of occupants with the car interiors. It also increases the effectiveness of airbags by keeping the occupants positioned correctly.
Seat belts were invented by English engineers in early 19th century and developed over time. Then a doctor came into the picture. In 1946, Dr. Hunter Sheldon, a neurosurgeon in California came with the first idea of retractable seat belt. You will be amazed to know that he was the one who later proposed various other safety features like reinforced roofs, roll-bars, door locks and even airbags.
Seat belts first appeared in American cars- Nash and Ford in 1940s. Then, Swedish manufacturer Volvo was the first to introduce modern 3-point seat belts design in 1959 as seen in cars of today. But for the sake of public safety, Volvo made the patent available to other car manufacturers for free. Just imagine if we had the option of seat belts only in expensive Volvo cars.
As I have told seat belts were developed in America and Europe but the world’s first seat belt law came up in 1970 in Australia.
A Seat belt is the cheapest and very effective safety feature available in every car. Many of you might be aware that road traffic accidents are leading non-medical cause of deaths worldwide and leading cause of death among young people aged 15-29. Wearing a seat belt reduces the risk of fatality among front seat passengers by 40-50% and of rear seat passengers by between 25-75%. If correctly installed and used, child restraints reduce deaths among infants by approximately 70% and deaths among small children by between 54% and 80%.
