3-Point Seat Belt

3-point seat belt is known as the universal seat belt which is extensively used in almost every vehicle nowadays. It was invented by Volvo engineer, Nils Bohlin in 1959.

The invention offers more value as a free life-saving tool, saving more lives ahead of corporate profits, which made Volvo gave away the patent of their most important invention to be installed in any vehicle regardless from different vehicle manufacturers.

3-point seat belt is a vehicle safety device, built in a Y-shaped configuration that goes over the waist (lap) and the shoulder of the occupant, designed to hold the occupant of a vehicle and spreads out the energy of the moving body over the chest, pelvis, and shoulders during a collision or at a sudden stop/de-acceleration.

We should be thankful to Nils Bohlin and Volvo as the invention continues to protect millions of people from death and/or serious injuries in car accidents every year, especially if we were once involved in a car accident.
