Are you curious as to who invented the seat belt used in all today's vehicles?

The Swedish car manufacturer Volvo has begun seeking enhancements to seat belts since mid-twentieth century. At the beginning, the company experimented with a single strap over the belly but sadly, abdominal injuries were still unavoidable in high-speed collisions. More than that, Volvo's engineers also trialed a diagonal chest restraint yet finally, it beheaded crash-test dummies.

Afterwards, the Swedish marque turned to Nils Bohlin – a 38-year-old engineer who had developed Saab aircraft company’s pilot ejector seats. Since passengers in car want both safe and comfort, transferring aerospace tech to automobile would be a demanding task, according to Bohlin.

However, after a year experimentation and research, he achieved a significant breakthrough - the most effective safety device ever – 3 point seat belt which includes one strap across the hips and another across the chest, each tied up at the same point. This kind of seat belt was so straightforward that driver and occupants were able to fasten with one hand. Volvo introduced its fruit 50 years ago and other carmakers followed suit.

Up to now, we cannot count exactly how many lives Nils’ 3 point seat belts has saved. The only we know is that the unanimity among safety experts is no less than a million. Nonetheless, there’s no denying that some drivers have been involved in accidents owing to wearing seatbelts.
