What car manufacturer gave away their patent for the seat-belt in the interest of saving lives?

Volvo is the car manufacturer that gave away their patent for the seatbelt in the interest of saving lives. In 1959, Volvo's CEO at the time, Nils Bohlin, invented the three-point seatbelt, a significant improvement over the two-point lap belt used by other car manufacturers. Instead of capitalizing on the invention, Volvo decided to share this life-saving technology with other automakers. By forgoing their patent rights and making the seatbelt design available to all, Volvo's selfless act revolutionized vehicle safety and helped save countless lives globally.
