/ˈsiːt belt//ˈsiːt belt/

The term "seat belt" was coined in the 1950s as a result of the need to provide additional safety to car passengers. Prior to the invention of seat belts, car manufacturers solely focused on designing sturdy and reliable vehicles, assuming that the vehicle's structure would offer sufficient protection to occupants in the event of an accident. However, in the early 1950s, safety concerns began to rise as the number of car accidents increased. In response to these concerns, engineer Nils Bohlin proposed a new safety feature – a three-point seat belt system. The name "seat belt" is derived from the function of this invention, which is used to hold car passengers in place while seated, thus reducing the risk of injury during collisions or sudden stops. The name "seat belt" combines the words "seat" and "belt" to denote the attachment of the belt to the seat. The three-point seat belt system includes two shoulder straps and a lap strap, which work together to secure the occupant in an upright position during the event of a collision, minimizing the risk of injury. The initial reaction to seat belts was mixed, as some drivers and passengers found them uncomfortable to wear. However, as the safety benefits of seat belts became more evident, they gradually gained acceptance in the automotive industry. Today, seat belts are mandatory safety equipment in all passenger cars globally, with seat belts' widespread adoption credited to their significant contribution to reducing traffic fatalities and injuries.
