A seat belt, also known as a safety belt or spelled seatbelt, is a vehicle safety device designed to secure the driver or a passenger of a vehicle against harmful movement that may result during a collision or a sudden stop. A seat belt reduces the likelihood of death or serious injury in a traffic collision by reducing the force of secondary impacts with interior strike hazards, by keeping occupants positioned correctly for maximum effectiveness of the airbag, and by preventing occupants being ejected from the vehicle in a crash or if the vehicle rolls over.
An airbag is a vehicle occupant-restraint system using a bag designed to inflate extremely quickly, then quickly deflate during a collision. It consists of the airbag cushion, a flexible fabric bag, an inflation module, and an impact sensor. The purpose of the airbag is to provide a vehicle occupant with soft cushioning and restraint during a collision. It can reduce injuries between the flailing occupant and the interior of the vehicle.
A crash test dummy, or simply dummy, is a full-scale anthropomorphic test device (ATD) that simulates the dimensions, weight proportions and articulation of the human body during a traffic collision. Dummies are used by researchers, automobile and aircraft manufacturers to predict the injuries a person might sustain in a crash. Modern dummies are usually instrumented to record data such as velocity of impact, crushing force, bending, folding, or torque of the body, and deceleration rates during a collision.
Automotive safety is the study and practice of automotive design, construction, equipment and regulation to minimize the occurrence and consequences of traffic collisions involving motor vehicles. Road traffic safety more broadly includes roadway design.
A school bus is any type of bus owned, leased, contracted to, or operated by a school or school district. It is regularly used to transport students to and from school or school-related activities, but not including a charter bus or transit bus. Various configurations of school buses are used worldwide; the most iconic examples are the yellow school buses of the United States which are also found in other parts of the world.
A car seat is the seat used in automobiles. Most car seats are made from inexpensive but durable material in order to withstand prolonged use. The most common material is polyester.
Seat belt legislation requires the fitting of seat belts to motor vehicles and the wearing of seat belts by motor vehicle occupants to be mandatory. Laws requiring the fitting of seat belts to cars have in some cases been followed by laws mandating their use, with the effect that thousands of deaths on the road have been prevented. Different laws apply in different countries to the wearing of seat belts.
The National Traffic and Motor Vehicle Safety Act was enacted in the United States in 1966 to empower the federal government to set and administer new safety standards for motor vehicles and road traffic safety. The Act was the first mandatory federal safety standards for motor vehicles. The Act created the National Highway Safety Bureau. The Act was one of a number of initiatives by the government in response to increasing number of cars and associated fatalities and injuries on the road following a period when the number of people killed on the road had increased 6-fold and the number of vehicles was up 11-fold since 1925. The reduction of the rate of death attributable to motor-vehicle crashes in the United States represents the successful public health response to a great technologic advance of the 20th century—the motorization of America.
A child safety seat, sometimes called an infant safety seat, child restraint system, child seat, baby seat, car seat, or a booster seat, is a seat designed specifically to protect children from injury or death during vehicle collisions. Most commonly these seats are purchased and installed by car owners, but car manufacturers may integrate them directly into their vehicle's design and generally are required to provide anchors and ensure seat belt compatibility. Many jurisdictions require children defined by age, weight, and/or height to use a government-approved child safety seat when riding in a vehicle. Child safety seats provide passive restraints and must be properly used to be effective. However, research indicates that many child safety restraints are often not installed or used properly. To tackle this negative trend, health officials and child safety experts produce child safety videos to teach proper car seat installation to parents and caregivers.
Head restraints are an automotive safety feature, attached or integrated into the top of each seat to limit the rearward movement of the adult occupant's head, relative to the torso, in a collision — to prevent or mitigate whiplash or injury to the cervical vertebrae. Since their mandatory introduction in some countries beginning in the late 1960s, head restraints have prevented or mitigated thousands of serious injuries.
Most seat belt laws in the United States are left to the states and territories. However, the first seat belt law was a federal law, Title 49 of the United States Code, Chapter 301, Motor Safety Standard, which took effect on January 1, 1968, that required all vehicles to be fitted with seat belts in all designated seating positions. This law has since been modified to require three-point seat belts in outboard-seating positions, and finally three-point seat belts in all seating positions. Seat belt use was voluntary until New York became the first state to require vehicle occupants to wear seat belts, as of December 1, 1984. New Hampshire is the only state that has no enforceable laws requiring adults to wear seat belts in a vehicle.
The Federal Motor Vehicle Safety Standards (FMVSS) are U.S. federal vehicle regulations specifying design, construction, performance, and durability requirements for motor vehicles and regulated automobile safety-related components, systems, and design features. They are the U.S. counterpart to the UN Regulations developed by the World Forum for Harmonization of Vehicle Regulations and recognized to varying degree by most countries except the United States. Canada has a system of analogous rules called the Canada Motor Vehicle Safety Standards (CMVSS), which overlap substantially but not completely in content and structure with the FMVSS. The FMVSS/CMVSS requirements differ significantly from the international UN requirements, so private import of foreign vehicles not originally manufactured to North American specifications is difficult or impossible.
When a person makes a claim for personal injury damages that have resulted from the presence of a defective automobile or component of an automobile, that person asserts a product liability claim. That claim may be against the automobile's manufacturer, the manufacturer of a component part or system, or both, as well as potentially being raised against companies that distributed, sold or installed the part or system that is alleged to be defective.
A five-point harness is a form of seat belt that contains five straps that are mounted to the car frame. It has been engineered for an increase of safety in the occurrence of an automobile accident. As a result, this form of seat belt has been mandated in the race car competition of NASCAR. This was an invention made mandatory to have due to the high velocities involved in the sport. Along with the design of the seat belt, helmet straps have been designed to increase the safety of the driver. This invention has also been used to secure infants and young children in child safety seats.
Takata Corporation was a Japanese automotive parts company. The company had production facilities on four continents, with its European headquarters located in Germany. In 2013, a series of deaths and injuries associated with defective Takata airbag inflators made in their Mexico plant, led Takata to initially recall 3.6 million cars equipped with such airbags. Further fatalities caused by the airbags have led the National Highway Traffic Safety Administration (NHTSA) to order an ongoing, US-wide recall of more than 42 million cars, the largest automotive recall in U.S. history. In June 2017, Takata filed for bankruptcy. It was acquired by Key Safety Systems.
Michael Henderson is a physician who has made contributions to motor vehicle safety. After moving from the United Kingdom to Australia, Henderson headed the new Traffic Accident Research Unit in the Department of Motor Transport in New South Wales. He wrote an early book on safety in motor racing and was involved in the design of a Pininfarina racing car built with the intent of increasing safety.
Motor Vehicle Manufacturers Association v. State Farm Mutual Automobile Insurance Co., 463 U.S. 29 (1983), is a United States Supreme Court decision concerning regulations requiring passive restraints in cars. In it, the Court struck down an order by the National Highway Traffic Safety Administration rescinding regulations that required either airbags or automatic seat belts in new cars.
Federal Motor Vehicle Safety Standard 208 regulates automotive occupant crash protection in the United States. Like all other Federal Motor Vehicle Safety Standards, FMVSS 208 is administered by the United States Department of Transportation's National Highway Traffic Safety Administration.
The National Child Passenger Safety Board, managed by the National Safety Council, maintains the quality and integrity of the National Child Passenger Safety Certification Training Program in the United States. The program is used to train and certify child passenger safety technicians and instructors in order to assist caregivers in safe transportation of children. Three of the most common issues that put children at risk: improperly used or installed safety seats, hot cars, and teen drivers. The Board is not limited to keeping kids safe in cars in the U.S. The work of Dr. Marilyn J. Bull to help shape automobile safety law in Chile was highlighted in March 2017 by AAP News.
Newborn care and safety are activities and precautions recommended for new parents or caregivers. It is an educational goal of many hospitals and birthing centers to promote newborn care and safety as parents take their infant home.
