A seat belt is used to prevent a passenger in a car from being thrown off his or her seat in an accident by fixing him or her to the seat and absorbing the impact shock. PET woven fabrics are usually used for their webbing. PET is more suitable than nylon for the webbing because PET has a higher impact-energy-absorbing capability and suffers less discoloration by sunlight. There are several standards for the webbing such as the Federal Motor Safety Standard, Economic Commission for Europe and Japan Industrial Standard. The main mechanical requirements of these standards are strength, width, elongation, and energy absorption ratio. There are also requirements related to durability such as wearing resistance, cold and heat resistance, water resistance, light-degradation resistance, and color fastness. Typical examples of specification values of PET fiber for this end use are yam thickness 1000-2500 dtex with 4-25 dtex of its monofilament thickness and strength 8-10 cN/dtex.

By law, the driver and all passengers (with a few exceptions) must use seat belts. The most popular seat belts are three-point mounting. Front seat belts usually have an inertia reel device to make them self-adjusting. For race and rally cars four- or five-point mounting seat harnesses are used.

In general, seat belt use has a significant impact on the safety of drivers and passengers in the event of a crash. Seat belts are intended to keep individuals securely in their seats, preventing them from being thrown out of the vehicle or colliding with other passengers, thereby reducing the risk of injury or death. Furthermore, seat belts also help drivers maintain control of their vehicles during a crash, allowing them to continue steering and braking, which can help prevent additional crashes from happening. These benefits make it evident that using seat belts is an essential aspect of safe driving. Existing literature has statistically confirmed the safety benefit of the seatbelt in reducing the severity of injuries (Peng and Boyle 2012; Schneider et al. 2009; Xie et al. 2012). In terms of statistical analysis, these previous studies have treated the usage of the seatbelt restraint system as an explanatory indicator in the crash severity model. However, some previous studies have shown that the use of safety devices, such as airbags and seatbelts in vehicles, can also lead to offsetting behavior, where drivers exhibit more aggressive behavior as a result of feeling protected (Abay et al. 2013; Winston et al. 2006). On the other hand, according to Eluru and Bhat (2007) and de Lapparent (2008), drivers who did not wear seat belts were found to display more aggressive driving behaviors, increasing their chances of being involved in more severe crashes.

The main aim of the road transport system is to ease and assist people’s mobility from one place to another. Nevertheless, this system comes with a significant risk, including road traffic accidents. Reports indicated that in 2016, nearly 1.24 million people were killed while between 20 and 50 million people were disabled as a result of vehicle-related accidents (National Highway Traffic Safety Administration, 2018). Seat belts prevent vehicle users from being thrown out from the vehicle or getting hit by objects close by during vehicle accidents. Although seat belts have life-saving potentials (Beck et al., 2018; Goetzke & Islam, 2015; Gras et al., 2007; Lajunen & Räsänen, 2004; Mehri et al., 2015; National Highway Traffic Safety Administration, 2018; Tavafian et al., 2015), 48% of people globally fail to fasten their safety belts (National Highway Traffic Safety Administration, 2018). The National Highway Traffic Safety Administration (NHTSA) estimated that the number of deceased front-seat passengers would be reduced by 45% if the seat belt usage was 100% (Van Houten et al., 2014). However, the massive number of vehicle accidents and low safety belt use rates may increase the traffic accident injuries and fatalities in the years to come (Huang et al., 2011).
Exploring new methods and new areas for safety

Safety belts or seat belts have evolved as an effective restraint system for car occupants since early 1970s. Most countries have mandated the use of seat belts in passenger cars by law. However, use of safety belts in buses, has been under discussion for many years. Recently, seatbelts have been introduced in intercity buses in a few countries. More recently its use has become mandatory in Ghana. Paul Okyere, et al, from Ghana and the USA have made a presentation on seat-belt use by inter-city bus passengers in Ghana. It was observed that the number of passengers on an intercity bus who used the seat-belt increased when prompted to do so by the driver. The self-reported passengers tended to over inflate seat-belt use as compared to those whom the survey covered. We hope to report more studies measuring the effectiveness of seatbelts in buses in future.
