A three-point seat belt.
A three-point seat belt.

A seat belt, sometimes called a safety belt, is a safety harness designed to secure the occupant of a vehicle against harmful movement that may result from a collision or a sudden stop. As part of an overall occupant restraint system, seat belts are intended to reduce injuries by stopping the wearer from hitting hard interior elements of the vehicle or other passengers (the so-called second impact) and by preventing the passenger from being thrown from the vehicle. The Seatbelts , also known as SEATBELTS) is a Japanese blues/jazz band led by composer and instrumentalist Yoko Kanno. ... Image File history File links Seatbelt. ...

Types of seat belts

  • Lap: Adjustable strap that goes over the waist. Used frequently in older cars, now uncommon except in some rear middle seats. Passenger aircraft seats also use lap seat belts.
  • Sash: Adjustable strap that goes over the shoulder. Used mainly in the 1960s, but of limited benefit because it is very easy to slip out of in a collision.
  • Lap and Sash: Combination of the two above (two separate belts). Mainly used in the 1960s and 1970s and still today in small aircraft. Generally superseded by three-point design.
  • Three-point: Similar to the lap and sash, but one single continuous length of webbing. Both three-point and lap-and-sash belts help spread out the energy of the moving body in a collision over the chest, pelvis, and shoulders. Until the 1980s three-point belts were commonly available only in the front seats of cars, the back seats having only lap belts. Evidence of the potential for lap belts to cause separation of the lumbar vertebrae and the sometimes associated paralysis, or "seat belt syndrome", has led to a revision of passenger safety regulations in nearly all of the developed world requiring that all seats in a vehicle be equipped with three-point belts. Since September 1, 2007, all new cars sold in the U.S. require a lap and shoulder belt in the center rear.[1]
  • Criss-cross: Experimental safety belt presented in the Volvo SCC. It forms a cross-brace across the chest.[2]
  • Five-point harnesses: Safer but more restrictive than most other seat belt types. They are typically found in child safety seats and in racing cars. The lap portion is connected to a belt between the legs and there are two shoulder belts, making a total of five points of attachment to the seat. (Strictly speaking, harnesses are never to be fastened to the seat—they should be fastened to the frame/sub-frame of the automobile.)
  • Six-point harnesses: Similar to a five-point harness but includes an extra belt between the legs, which is seen by some to be a weaker point than the other parts. These belts are used mainly in racing. In NASCAR, the six-point harness became popular after the death of Dale Earnhardt. Earnhardt was wearing a five-point harness when he suffered his fatal crash. As it was first thought that his belt had broken, some teams ordered a six-point harness in response.
  • Seven-point harnesses (5+2): Aerobatic aircraft frequently use a combination harness consisting of a five-point harness with a redundant lap-belt attached to a different part of the airframe. While providing redundancy for negative-g maneuvers (which lift the pilot out of the seat), they also require the pilot to un-latch two harnesses if it is necessary to parachute from a failed aircraft.

Seat belts were invented by George Cayley in the late 1800s.[citation needed] They were introduced in aircraft for the first time in , by Adolphe Pegoud, who became the first man to fly a plane upside-down. However, seat belts did not become common on aircraft until the 1930s.

American physicians in the 1920s advocated the use of seat belts in cars. Some of them even outfitted their cars with seatbelts. Plastic surgeon Claire L. Straith and physician C. J. Strickland were at the forefront of that demand. Strickland founded the Automobile Safety League of America. The American public showed little interest. [4] Claire L.

Edward J. Hock invented the safety belt first used by the Ford Motor Company as standard equipment, while he was on active duty with the military as a flight instructor. In 1955 his idea was accepted by the naval authorities, and Hock was awarded $20.50 for his invention. The original schematic and blueprints shows that he utilized scrap parachute strapping to implement his idea.

Seat Belt uncovered Inertial Reel
Seat Belt uncovered Inertial Reel

Most seat belts are equipped with locking mechanisms (or inertia reels) that tighten the belt when pulled fast (e.g. by the quick force of a passenger's body during a crash) but do not tighten when pulled slowly. This is implemented with a centrifugal clutch, which engages as the reel spins quickly. Alternatively, this function may be secured by a weighted pendulum or ball bearing: when these are deflected by deceleration or roll-over they lock into pawls on the reel.

Types of inertia reel type seatbelts:

NLR (No Locking Retractor): Commonly used in recoiling lap belts

ELR V (Emergency Locking Retractor - Vehicle sensitive): Single sensitive mechanism, composed of a locking mechanism activated in an emergency by deceleration or rollover of the vehicle. Thus, the seatbelt is sensitive to the vehicle's motion.

ELR VW (Emergency Locking Retractor - Vehicle and Webbing sensitive): Dual sensitive means a seatbelt retractor that, during normal driving conditions, allows freedom of movement by the wearer of the seatbelt by means of length-adjusting components that automatically adjust the strap to the wearer, with a locking mechanism that is activated by two or more of the following:

  • deceleration or rollover of the vehicle,
  • acceleration of the strap (webbing) from the retractor, or
  • other means of activation.

Pretensioners and webclamps

Seatbelts in many newer vehicles are also equipped with "pretensioners" and/or "Webclamps".

  • Pretensioners preemptively tighten the belt to prevent the occupant from jerking forward in a crash. Mercedes-Benz first introduced pretensioners on the 1981 S-Class. In the event of a crash, a pretensioner will tighten the belt almost instantaneously. This reduces the motion of the occupant in a violent crash. Like airbags, pretensioners are triggered by sensors in the car's body, and most pretensioners use explosively expanding gas to drive a piston that retracts the belt. Pretensioners also lower the risk of "submarining", which is when a passenger slides forward under a loosely worn seat belt.
  • Webclamps clamp the webbing in the event of an accident and limit the distance the webbing can spool out (caused by the unused webbing tightening on the central drum of the mechanism) these belts also often incorporate an energy management loop ("rip stitching") which is when the lower part of the webbing is looped and stitched with a special stitching. The function of this is to "rip" at a predetermined load, which reduces the load transmitted through the belt to the occupant, reducing injuries to the occupant.

Automatic seat belts

Main article: Automatic seat belt

Some vehicles have shoulder belts that automatically move forward to secure the passenger when the vehicle is started. A separate lap belt is usually included, and the lap belt must be fastened manually. Automatic seat belts have fallen out of favor recently, since the airbag became mandatory in many countries.

Use of seat belts by child occupants

Main article: Infant car seat

As with adult drivers and passengers, the advent of seat belts was accompanied by calls for their use by child occupants, including legislation requiring such use. It has been claimed that children in adult restraints suffer lower injury risk than unrestrained children. An infant safety seat, a child restraint system or restraint car seat is a restraint which is secured to the seat of an automobile equipped with safety harnesses to hold an infant or small stature people in the event of a crash. ...

The UK extended compulsory seatbelt wearing to child passengers under the age of 14 in 1989. It was observed that this measure was accompanied by a 10% increase in fatalities and a 12% increase in injuries among the target population[8]. In crashes, small children who wear adult seatbelts can suffer characteristic "seat-belt syndrome" injuries including severed intestines, ruptured diaphragms and spinal damage. There is also research suggesting that children in inappropriate restraints are at significantly increased risk of head injury[9], one of the authors of this research has been quoted as claiming that "The early graduation of kids into adult lap and shoulder belts is a leading cause of child-occupant injuries and deaths."[10] As a result of such findings, many jurisdictions now advocate and/or require child passengers to use specially designed child restraints. Such systems include separate child-sized seats with their own restraints and booster cushions for children using adult restraints. In some jurisdictions children below a certain size are forbidden to travel in front car seats.

Use of seat belts by expectant mothers

For pregnant mothers, the fetus is protected by a sac full of amniotic fluid. This sac is quite strong and the fluid inside acts like a cushion to protect the fetus. The sac is pliable so it can change shape to a certain degree. The proper use of a seat belt will divert the pressure points off the sac, and thus the fetus would only be minimally affected. The lap belt should be worn low over the pelvic bones and not against the soft stomach area. The shoulder belt should be worn across the chest. Both should be worn snugly.[11]

Reminder chime and light

In North America and some other parts of the world, cars sold since the early 1970s have included a seat belt light on the dashboard, reminding the driver and passengers to buckle up. These systems also included a warning buzzer which sounded for several seconds before turning off (with the warning light), regardless of whether the car was started. New cars sold in the United States in 1974 and the first part of the 1975 model year were sold with a special "ignition interlock", whereby the driver could not start the car until the seat belt was fastened; however, this system was short-lived.

By the early 1980s, many automakers selling in the U.S. market had replaced the buzzer (along with all other buzzers for functions such as headlights-on) with a seatbelt warning chime, though for some models, this change was not implemented until the 1990s or even the early 2000s. Today, many of these carmakers use a red figure with its seatbelt on to serve as its seatbelt warning light, and it may stay on for several minutes after the car is started and the driver's seat belt is not fastened.

In Europe most modern cars include a seat-belt reminder light for the driver and some also include a reminder for the passenger, when present, activated by a pressure sensor under the passenger seat. In some systems (i.e. older Volvos), the seatbelt is connected to the turn signal relay, making clicking sounds constantly until the front passengers are buckled up. Turn signals (US English) or indicators (British English) are a set of lights on a vehicle (be it a car, truck/lorry, tractor, motorcycle, etc. ...

Some newer cars from Audi, BMW, Ford, Honda, Hyundai, Mercedes-Benz, and Toyota will intermittently flash the reminder light and sound the chime until the driver (and sometimes the front passenger, if present) fasten their seatbelt.

Main article: Seat belt legislation

Observational studies of car crash morbidity and mortality,[12][13][14] experiments using both crash test dummies and human cadavers indicate that wearing seat belts greatly reduces the risk of death and injury in the majority of car crashes. Seat belt legislation is a law or laws put in place to enforce or require, the fitting of seat belts to motor vehicles, or the wearing of seat belts by motor vehicle occupants. ... In statistics, the goal of an observational study is to draw inferences about the possible effect of a treatment on subjects, where the assignment of subjects into a treated group versus a control group is outside the control of the investigator. ... A car accident in Yate, near Bristol, England, in July 2004. ... In the scientific method, an experiment (Latin: ex- periri, of (or from) trying) is a set of observations performed in the context of solving a particular problem or question, to retain or falsify a hypothesis or research concerning phenomena. ... Crash test dummies have saved many thousands of lives. ... For other uses, see Cadaver (disambiguation). ... For other uses, see Death (disambiguation). ...

This has led many countries to adopt mandatory seat belt wearing laws. It is generally accepted that, in comparing like-for-like accidents, a vehicle occupant not wearing a properly fitted seat belt has a significantly higher chance of death and serious injury. One large observation studying using US data showed that the odds ratio of crash death is 0.46 with a three-point belt, when compared with no belt.[15] In another study, that examined injuries presenting to the ER pre- and post-seat belt law introduction, it was found that 40% more escaped injury and 35% more escaped mild and moderate injuries.[16] The odds-ratio is a statistical measure, particularly important in Bayesian statistics and logistic regression. ... The emergency room is the American English term for a room, or group of rooms, within a hospital that is designed for the treatment of urgent and medical emergencies. ...

The effects of seat belt laws are disputed by some, stemming from the observation that following the passage of seat belt laws, road fatalities often did not decrease. There was also concern that instead of legislating for a general protection standard for vehicle occupants, laws that required a particular technical approach would rapidly become dated as motor manufacturers would tool up for a particular standard which could not easily be changed. For example, in 1969 there were competing designs for lap and 3-point seat belts, rapidly-tilting seats, inflatable restraints and air bags being developed. But as countries started to mandate seat belt restraints the global auto industry invested in the tooling and standardized exclusively on seat belts, and ignored other designs, such as air bags, for several decades[17] For the Radiohead song, see Airbag (song). ...

Risk compensation

Some have proposed that the number of deaths was influenced by the development of risk compensation, which says that drivers adjust their behaviour in response to the increased sense of personal safety wearing a seat belt provides. In ethology, risk compensation is an effect whereby individual animals may tend to adjust their behaviour in response to perceived changes in risk. ...

In one trial subjects were asked to drive go-karts around a track under various conditions. It was found that subjects who started driving unbelted drove consistently faster when subsequently belted.[18] Similarly, a study of habitual non-seatbelt wearers driving in freeway conditions found evidence that they had adapted to seatbelt use by adopting higher driving speeds and closer following distances.[19] Similar responses have been shown in respect of anti-lock braking system and, more recently, airbags and electronic stability control.[citation needed] A kart racer takes a turn on an indoor track Kart racing (as the word is so spelled by enthusiasts) or karting is a variant of open-wheeler motor sport with simple, small four-wheeled vehicles called karts, go-karts, or gearbox/shifter karts depending on the design. ... An anti-lock braking system (ABS) (translated from German, Antiblockiersystem) is a system on motor vehicles which prevents the wheels from locking while braking. ... An airbag is a flexible membrane or envelope, inflatable to contain air or some other gas. ... Electronic Stability Control (ESC) is a computerized system designed to improve a vehicles handling by intervening at the limits of traction and helping the driver maintain control of the vehicle. ...

A 2001 analysis of US crash data aimed to establish the effects of seatbelt legislation on driving fatalities[20] and found that previous estimates of seatbelts effectiveness had been significantly overstated. According to the analysis used, seatbelts were claimed to have decreased fatalities by 1.35% for each 10% increase in seatbelt use. The study controlled for endogenous motivations of seat belt use, which it is claimed creates an artificial correlation between seat belt use and fatalities, leading to the conclusion that seatbelts cause fatalities. For example, drivers in high risk areas are more likely to use seat belts, and are more likely to be in accidents, creating a non-causal correlation between seatbelt use and mortality. After accounting for the endogeneity of seatbelt usage, Cohen and Einav found no evidence that the risk compensation effect makes seatbelt wearing drivers more dangerous, a finding at variance with other research.

Increased traffic

Other statistical analyses have included adjustments for factors such as increased traffic, and other factors such as age, and based on these adjustments, a reduction of morbidity and mortality due to seat belt use has been claimed.[12] However, Smeed's law predicts a fall in accident rate with increasing car ownership and has been demonstrated independently of seatbelt legislation. Smeeds Law, after RJ Smeed who first proposed the relationship in 1949, is an empirical rule relating traffic fatalities to motor vehicle registrations and population. ...
