A 3-point belt is a Y-shaped arrangement, similar to the separate lap and sash belts, but unitized. Like the separate lap-and-sash belt, in a collision the 3-point belt spreads out the energy of the moving body over the chest, pelvis, and shoulders. Volvo introduced the first production three-point belt in 1959.[16] The first car with a three-point belt was a Volvo PV 544 that was delivered to a dealer in Kristianstad on August 13, 1959. However, the first car model to feature the three-point seat belt as a standard item was the 1959 Volvo 122, first outfitted with a two-point belt at initial delivery in 1958, replaced with the three-point seat belt the following year.[17] The three-point belt was developed by Nils Bohlin who had earlier also worked on ejection seats at Saab.[18] Volvo then made the new seat belt design patent open in the interest of safety and made it available to other car manufacturers for free.[19][20] @Curionic
