First appearing in the PV 544 Sedan seen here, three-point seat belts were introduced by what company?

In 1950, the Nash Airflyte became the first American car to offer across the waist seat belts. Volvo introduced the three-point seatbelt in 1959. Volvo patented its belt design but allowed anyone to use it.
