1965
The 1966 Pontiac GTO typically came with a rear seat that had two sets of seat belts. These were standard lap belts for the outboard seating positions, while the middle seat did not have a seat belt. Optional shoulder belts could be added, but they were not included as standard equipment.
I believe it was the first year of seat belts being standard equipment on the Thunderbird.
In the year 1949 seat belts became an option in cars.

Not necessarily. By 1964, Most U.S. automobiles were sold with standard front seat belts; rear seat belts were made standard in 1968. So there were cars sold in 1960 that did not have seat belts.
