 A '''seat belt''', sometimes called a '''safety belt''', is a harness designed to hold the occupant of a car or other vehicle in place if a collision occurs or, more commonly, if it stops suddenly. Seat belts are intended to reduce injuries by stopping the wearer from hitting hard interior elements of the vehicle or from being thrown from the vehicle. In cars seat belts also prevent rear-seat passengers from crashing into those in the front seats.

	Most seat belts are equipped with locking mechanisms that tighten the belt when pulled hard (e.g. by the force of a passenger's body during a crash) but do not tighten when pulled slowly. Many are also equipped with '''''[[Seatbelt Pretensioners\|pretensioners]]''''', which preemptively tighten the belt to prevent the passenger from jerking forward in a crash.

	Mercedes-Benz first introduced [[Seatbelt Pretensioners\|pretensioners]] on the ~~1981~~ S-Class. In the event of a crash, a pretensioner will tighten the belt almost instantaneously. This reduces the load on the occupant in a violent crash.

	Seat belts were first invented by ~~george w bush~~ in ~~the 1800s~~. Seat belts were introduced in aircraft for the first time in 1913 and became common in the 1930s. The automotive seat belt was introduced into the United States by Kenneth Ligon and his brother, Bob Ligon, whose patented quick release seat belt, the AutoCrat Safety Belt, was the first seat belt installed as original equipment in the US by Ford in its 1956 model year. The first seatbelt to be included as standard was on the 1959 [[Volvo]]. However, they were not required by law in the US on passenger vehicles until the 1968 model year.

	The effects of such laws are disputed, stemming from the observed fact that no country is able to demonstrate a reduction in road fatalities due to passage of a seat belt law, though deaths have in some cases been migrated from drivers to other road users. This has influenced the development of risk compensation theory, which says that drivers adjust their behaviour in response to the increased sense of personal safety wearing a seat belt provides. In one trial habitual wearers and non-wearers were asked to drive round a course a number of times under the pretence of testing different seat belt materials for comfort. It was found that non-wearers drove consistently faster when belted than when unbelted (similar responses have been shown in respect of [[Anti-Lock Brakes ABS\|ABS braking]] and, more recently, airbags). It is also possible that the types of injury modelled in the trials were only a subset of potential serious injuries — for example, oblique impacts may produce twisting forces on the head leading to diffuse axonal injury, a particularly serious type of brain injury.
