The automotive seat belt, as we know it today was first offered on Nash as an option in 1949. Ford followed with optional seat belts in 1955. The first vehicle to offer standard seat belts was Saab, in 1958.
During the 1960s, seat belts became optional in virtually all cars offered in the U.S. Many of the seat belts were dealer installed options, and the engineering wasn’t ideal. The belt kits themselves, were similar to safety belts used in aircraft, which included a friction adjuster and lift-up buckle, with nylon webbing. However the floor pans of early vehicles weren’t engineered to support seat belt loads in an accident.
By the later 1960s, cars were being designed with engineered seat belt attaching points in the car and shoulder belts were also being offered.
