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. [1] 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.
The five-point harness is preferred as a safety mechanism for its high amount of safety compared to other designs. [2] The five-point harness consists of five straps. Two are located at the shoulders, two at the hips, and one at the crotch that all come to connect to a buckle release mechanism. [3] [4] This way of buckling up holds the driver's body tight in the seat, which in turn protects the upper body from injury. The only downside to this seat belt mechanism is the insecurity of the driver's head. [4]
There have been different models of helmets designed to hold the drivers head in place. A helmet restraint is equipped in some five-point harness seats to prevent brain and neck injury. For example, in NASCAR, it protects the driver in case of a car crash or an immediate change of velocity where the driver has limited control of his momentum. [4] The apparatus consists of a strap that runs from both of the sides of the helmet to the vehicle; or a strap connected to the vehicle from both sides of the driver that runs across the front of the helmet, instead of two independent straps on each side attached to the helmet. The mechanism is called a HANS (head and neck support) device [4]
To prevent the helmet straps from impairing the drivers vision, there is a design where the straps are held horizontal to prevent the straps from sagging. [5] There are also designs in which no apparatus is needed to keep straps out of the drivers sight. [4] Helmet straps are made up of shock absorbing material used while climbing or for security when working at high elevations. The straps include a woven nylon that requires up to 475 lbs. of force to cause the straps to tear. [5] Straps that are stretchable allow the drivers brain to slow down to avoid brain damage caused from the brain slamming into the skull; but the straps do not let the head move too far forward to cause neck injuries.
The five-point harness is also used to buckle up children in forward-facing and rear-facing seats. It is designed with the same concept of tightly holding the passenger to the seat with the use of five different straps but built for the young children. This form of seat harness for young children "should be a default standard" when children are present in a motor vehicle according to Phil Wilson. [6] The reason there have been a number of injured young children and infants in survivable accidents is due to incorrect use of the Child Safety Seat (CSS). [3]
To assist caregivers in the safe transportation of children, the USA National Child Passenger Safety Board maintains the quality and integrity of the National Child Passenger Safety Certification Training Program. [7] The program is used to train and certify child passenger safety technicians and instructors. Three of the most common issues that put children at risk: improperly used or installed safety seats, children left in hot cars, and teen drivers. [8]
Tack is equipment or accessories equipped on horses and other equines in the course of their use as domesticated animals. This equipment includes such items as saddles, stirrups, bridles, halters, reins, bits, and harnesses. Equipping a horse is often referred to as tacking up, and involves putting the tack equipment on the horse. A room to store such equipment, usually near or in a stable, is a tack room.
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.
Webbing is a strong fabric woven as a flat strip or tube of varying width and fibres, often used in place of rope. It is a versatile component used in climbing, slacklining, furniture manufacturing, automobile safety, auto racing, towing, parachuting, military apparel, load securing, and many other fields.
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.
A HANS device is a type of head restraint, a safety device in motorsports. Head restraints are mandatory when competing with most major motorsports sanctioning bodies. They reduce the likelihood of head or neck injuries, including the often fatal basilar skull fracture, in the event of a crash. There are many such devices on the market today, but the HANS is the original and the most common.
A pet harness is equipment consisting of straps of webbing that loop nearly around—that fasten together using side release buckles—the torso of an animal.
A Hutchens device is used for protecting race car drivers in the event of an accident by controlling head movement, reducing head and neck injuries due to whiplash. It consists of a series of straps, attached to the helmet and connected across the chest and at the waist, depending on the lap belt for anchoring. The device was developed beginning in 2000.
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 the United States.
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.
Elwood Jesse "Bill" Simpson was an American racing driver, best known as a pioneer in the racing safety business with his company Simpson Performance Products. Later during his business career he branched into developing equipment for football safety.
A safety harness is a form of protective equipment designed to safeguard the user from injury or death from falling. The core item of a fall arrest system, the harness is usually fabricated from rope, braided wire cable, or synthetic webbing. It is attached securely to a stationary object directly by a locking device or indirectly via a rope, cable, or webbing and one or more locking devices. Some safety harnesses are used in combination with a shock-absorbing lanyard, which is used to regulate deceleration and thereby prevent a serious G-force injury when the end of the rope is reached.
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.
On the afternoon of February 18, 2001, American stock car racing driver and team owner Dale Earnhardt was killed instantly due to a basilar skull fracture in a final-lap collision in the 2001 Daytona 500, in which he crashed into a retaining wall after making contact with Sterling Marlin and Ken Schrader. He was pronounced dead at Halifax Medical Center a short time later.
Simpson Performance Products is an American motorsports parts supplier that manufactures safety products such as gloves, helmets, harness systems, driver's suits, head restraints, and shoes. It is marketed to racers ranging from participants at local track days to international Formula One and NASCAR teams. It was started by Bill Simpson as Simpson Drag Chutes.
Safety in NASCAR has evolved into one of the biggest concerns in stock car racing's largest sanctioning body. Mainly after the death of Dale Earnhardt, a seven time Winston Cup Series champion, NASCAR has decided to change all of their safety policies, such as the use of the HANS device. Since 2001, NASCAR has also changed the cars for the NASCAR Cup Series and the Xfinity Series. NASCAR's safety policy includes the racing fire suit, carbon fiber seating, and roof flaps.
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.
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.
