20Adjustable Seat Belts
Seat belts were a novel invention in 1949 when car manufacturer Nash first offered them as options, followed by Ford in 1955. According to the NHTS, they save more than 15,000 lives each year. But it was Nils Bohlin who invented the “modern” three-point seat belt, introducing the lap-and-shoulder adjustable
belt in 1959 with Volvo. These are now standard safety equipment in most vehicles, designed to keep you in your vehicle and to reduce the risk that you’ll collide with the steering wheel, dashboard, or windshield. Adjustable upper belts also help to accommodate passengers of any size and the pre-tensioners retract to remove excess slack, almost instantly, in a crash.
