evidence: In 1958 Volvo's efforts in creating an effective safety solution resulted in a patent application for Nils Bohlin's three-point safety belt. His design had four important properties: 1) The system consisted of a lap belt and a diagonal belt, 2) the belts were anchored at a low attachment point beside the seat, 3) the belt geometry formed a V shape with the point directed toward the floor and 4) the belt stayed in position and did not move in an impact. [...] Since the 1960s, Bohlin's three-point safety belt has saved many hundreds of thousands of lives and prevented or reduced the severity of injuries among many millions of others. This makes the three-point safety belt the single most important safety device in the car's 120-year history. [...] Since the 1960s, Volvo Cars has worked hard to increase belt usage. For instance, Nils Bohlin conducted a long presentation tour in the US introducing the three-point safety belt to convince the widest possible audience of its benefits.
