Volvo engineer Nils Bohlin invents the three-point seatbelt and gives it away
In 1959, Swedish engineer Nils Bohlin designed the three-point seatbelt at Volvo — a lap-and-shoulder strap that let the body’s strongest bones absorb a crash. Then Volvo did something unusual: they opened the patent to every automaker, free. Volvo estimates more than a million people have survived crashes because of it.
