In 1959, Volvo Cars engineer Nils Bohlin introduced the concept of the v-type three-point safety belts in Volvo vehicles. This cross-strap design made seat belts easier to use, and much safer. Volvo performed the standard industrial practice of patenting the design to protect their investments. This would have allowed Volvo to have a defensible advantage over competitors: 20 years of Monopoly rights in the U.S, the position to charge significant license fees to competitors, and/or maintain exclusivity to market their cars as the safest available.
Further demonstrating their extreme prioritization for safety, Volvo Cars took advantage of neither of these options. Rather, they opened the patent to allow, and even encourage, all competitors to adopt the design in the name of automotive safety.
