What inspired Nils Bohlin to invent the seat belt?

Nils Bohlin was inspired to invent the three-point seat belt by a combination of his engineering background and the need for improved automotive safety. Working with Volvo, he aimed to create a safety device that would effectively protect occupants during collisions. His design was motivated by the high rates of injuries and fatalities in car accidents, and he believed a simple, easy-to-use restraint could significantly enhance passenger safety. Bohlin's innovative seat belt has since saved countless lives and is now a standard feature in vehicles worldwide.
