Meet the Nils Bohlin and Gunnar Engellau, whose work at Swedish carmaker Volvo has helped save millions of lives worldwide.
Engellau, Volvo’s president and an engineer himself, helped push for a more effective seatbelt, after a relative died in a traffic accident due partly to the flaws of the two-point belt design—which was not even standard feature in cars at the time. This personal tragedy drove Engellau to find a better solution, hiring Bohlin to find a solution quickly.
There were two major problems with the historic two-point belt design, which crosses the lap only. First, because the human pelvis is hinged, a single strap fails to restrain the torso, leaving passengers vulnerable to severe head, chest and spinal injuries; positioned poorly, the belt can even crush internal organs on impact. Second, they were notoriously uncomfortable, so many people chose not to wear them. Bohlin’s innovation was to find a design that resolved both problems at once.
After millions of dollars and thousands of tests through the 1950s and 1960s, Volvo became the first carmaker in the world to standardize the three-point safety belt we now take for granted. More than that, Volvo pushed hard for the seatbelt to be adopted in its native Sweden, which like most places was initially resistant to having to wear seatbelts.
But Volvo didn’t stop there. While it patented the designs to protect their investment from copy-cats, the company did not charge significant license fees to rivals or keep the design to itself to give their cars an edge. Knowing that lives were at stake worldwide, Engellau made Bohlin’s patent immediately available to all. Having sponsored the costly R&D, they gifted their designs to competitors to encourage mass adoption. It is estimated that Volvo may have lost out on $400 million in additional profits, if not more.
Instead, literally millions of people have been spared injury and death by this now-ubiquitous seatbelt we take for granted. All because a couple of Swedes decided to put people over profits (which isn’t to say they didn’t reap any financial incentive, but proved you can do both).
