The history of belts goes long time back. They played crucial part in the industrial revolution. Belts were introduced as the basic means of power transmission, source of motion or relative movement. Power transmission belts date back to about 200 years before. The demands on a belt drive transmission system are large and this has led to many variations on the theme the materials have changed and the shapes have undergone modifications. Starting from leather, the list has reached up to synthetic fibers without compromising on the properties of belts such as strength, durability etc. A belt drive is simple, inexpensive, and does not require parallel shafts. It helps protect a car from overload and jam, damping it from noise and vibration. …show more content…
Fundamentally, it is designed to deliver non-recoverable extension to reduce the deceleration forces, which the body encounters in a crash. Basically, it is designed to offer non recoverable extension to decrease the deceleration forces that the body comes across in a crash. Non recoverable extension is significant to prevent the occupants from being restrained into their seats and sustaining whiplash injuries right away after a collision. An efficient seat belt will only permit its wearer to move forward a maximum of about 30 cm to avoid contact with any fixed parts of the car. Seat belt was invented concurrently in United States and Sweden. Earlier seat belts were fixed and adjusted manually by the wearer. With the introduction of automatic belts today wearer has more freedom to move. [9] 2.3.2.2 NEED FOR SEAT BELTS 1. In an auto smash, seat belts prevent ejection from a moving car and stop people going through the windshield as the vehicle comes to a sudden stop. Seat belts also minimize injuries due to impact with the vehicle's hard
Since the invention of the automobile, there have been many great innovations within the industry. The suspension of the automobile serves as a good example of one of those innovations. Could you imagine riding around in your brand new Nissan Skyline GT-R, with the same suspension methods used to stabilize old horse and carriage buggies centuries ago? That would not serve its purpose very well. Due to the demands of society, vehicle stabilization became a priority to increase safety. Throughout the years, there have been different variations of vehicle suspension systems. For example, we have adaptive air, solid axle, and dead axle suspensions. Without the advancements made in the way we travel and transport goods, civilization could not prosper the way it has.
These advantages, however, do not balance the many short falls of the belt drive design.
Is there in the world anything more essential than having a new opportunity of life? Although several individuals may possibly think an obligatory use of seat belt is a technique for causing people to feel a prisoner in their own car, putting on a seat belt would make the difference in a car accident. The use of seat belts provides security while driving; shows self-consciousness and has a role in government. That is why, the use of seat belts should be mandatory for drivers.
Many people may choose not to wear a seatbelt because they don’t understand how and why they work. To begin with seatbelts are the first line of defense one has against an injury in a crash.
Even though there are some statistics that may show a lower rate of injury or death if you wear a seat belt when in an automobile accident, I do not feel that the government has the right to make wearing a seat belt mandatory for adults because by making seat belts mandatory it takes away from our right to freedom of choice, and wearing a seat belt does not eliminate the risk of injury or death as people have been injured and/or killed due to wearing a seat belt Current seat belt law originated from federal legislation in the 1960s that made it mandatory for all automobile manufacturers to include seat belts in their vehicles as a standard feature. Originally, the purpose of a seat belt was not to protect the occupants in the case of a crash, but rather to physically keep them in the vehicle, as driving was bumpy business. However, in today’s times, mandatory use of a seat belt falls under various states purview. Each state implements its own laws regarding enforcement of seat belt use.
Seatbelt is a very important component when we all drive a car or other vehicle. The main purpose of seat belts is to provide greater safety to the driver when driving car but at the moment, people do not care about the importance of wearing seatbelt.
...ed as mats or runners in non critical applications and where cost is a factor. Typically used belts are good on one side and worn on the other side and not suitable to be used as conveyor belts any longer. Common thickness is in the ½” – ¾” range and widths can vary up to 96” wide; usually 24”-48” is most common width selected.
It may seem that by making the body of a vehicle extremely rigid, it would be more resistant in an accident than if it deformed. However, this will cause all the forces present during a crash to be transferred to the occupants of the vehicle, causing many injuries. Crumple zones are built into a vehicle to prevent the force of the impact from being transferred to the occupants in the vehicle by absorbing the energy of the impact before it reaches them. They were designed to take as much force as possible so the occupants as well as the vehicle do not suffer the effects.
During side impact crashes, cars can potentially flip. Side impact crashes are said to be the most dangerous type of car crash. The rear facing seat is the best option during this type of crash. If the car flips the sides of the seats are better equipped to harness the child in the seat. The seat is able to make pivoting motions because of the attachments to keep the child in a straight line. Keeping them in a straight line reduces the risk of injuries especially in the spinal cord.By having their back straight it won't bend or come close to snapping. A rear facing car seat protects the child by using a 5- point safety harness which is a system of hooks even used for race car drivers, and flight pilots.This allows the child to stay In the seat without them fal...
Car accidents are the leading cause of death for people under the age of 35. Wearing a seat belt can prevent death in about half of these accidents. Did you know that every 15 seconds someone is injured in an automobile accident if they are not buckled up, or that every 13 minutes someone is killed in a crash. Failure to wear a seat belt contributes to more fatalities than any other single traffic safety related behavior. According to the National Highway Traffic and Safety Administration seatbelts saved nearly 12,000 lives in the United States in the year 2000. The NHTSA estimates that more than 9,000 U.S. car accident fatalities in 2000 would have been avoided if the victims had been wearing seatbelts. Sixty three percent of the people killed in accidents were not wearing seat belts. The NHTSA a...
Seatbelts have been around since the 1950s and have proven to save lives over the years. The teenage stigma is that they do not need to wear one because they will be fine. After thousands of accidents where the occupants did not wear their seatbelt, the Supreme Court decided to pass some laws. “In 1972, the agency requires dull passive restraints for front seat occupants” (Supreme Court). The agency that the Supreme Court is referring to is the Department of Transportation. This law is a staple in automobile safety and sets a level of precedents for future laws. After this law was passed, the amount of fatalities from traffic incident relating to seat belts usage had dropped. The Supreme Court did not stop there, they continued to add more laws. “...new motor vehicles produced after September 1982 will be equipped with passive restraints to protect the safety of the occupants of the vehicle in the event of a collision” (Supreme Court). Now all new motor vehicles must have a form of passive restraint added to their vehicles before they can sell them to the public. The government hoped to protect more lives of young drivers who did not insist on wearing seat belts by making them mandatory and being enforced by police officers. Since 1972, hundreds of thousands of teenage lives have been saved with this simple safety
Shock absorbers, otherwise known as dampeners, reduce the vertical movement of the car as it drives down a rough surface. Without this piece of the suspension system, your car would rock and sway back and forth viciously. “It would be a traveling deathtrap. Or at least it would be a traveling deathtrap until the incessant vibration caused it to fall apart,” says Longhurst. Shock absorbers have two main functions. They both absorb any over-average bumps in the road, as I mentioned above, and secondly they keep your wheels on the ground as you drive. (Longhurst)
We have all heard the excuses before, “do I have to wear it? It isn’t like it’s going to protect me,” “it’s uncomfortable, I’m only going around the corner,” or “I’d rather be thrown out of the vehicle than to be stuck in a seat belt.” No matter how good of a driver you are, or you think you might be, there are always situations that are beyond your control. Such as, bad weather, drunk drivers, and road conditions. Sometimes, seat belts can be a life or death in an automobile accident. Not only is wearing your seat belt every time you get in a vehicle, but it is required by law in 49 states, with the exception of New Hampshire. Although seat belts are known to lock up and wrinkle your clothes, I believe that wearing your seat belt is beneficial because every fourteen seconds someone is injured in a traffic crash. Seat belts are not only known for holding you in place during a collision, but more importantly the are known to save the lives of the occupants in the vehicle.
Although there are many unsafe things that people should not do while driving such as, texting, reckless driving, speeding, and driving under the influence of drugs and alcohol, however, they still do it because they think they will not cause an accident. No one ever expects to get into a car accident one day while they are driving minding their own business heading towards their destination and suddenly being hit by someone ending up with head and back injuries and a broken hip bone or even fatality. The use of a seat belt may not save you from bodily injuries but it certainly can keep your body in place preventing you from being ejected out of a vehicle that has come to a halt. I’d rather be held in a car during a car accident than to be thrown on the side of a road any
Bull bars- A bull bar is a device attached to the front of the vehicle to minimise the damage caused to passenger in the case of a crash. Bull bars come in all different shapes and sizes depending on needs. If your car was to collide with a kangaroo, the car passengers would feel the thump because the mass of the kangaroo is big enough to cause damage. The car would also slow down naturally without the driver putting their foot on the brake, because the force has either been thrown forward or over the car (law 1 and 3). The bull bar is designed to stop the force from coming in contact with the cars bonnet.
