Why don t trains have seat belts 100

The train runs smoothly without major fluctuations, and the more crowded seats on the train can greatly increase the safety level and eliminate the need for seat belts.

Trains are relatively safe to travel on tracks. Because he was alone every time he drove, there was no vehicle that met him. And the train is relatively smooth when braking, so there is no need for seat belts.

The reason why trains do not have seat belts is because their speed and smoothness are different, and airplanes will encounter strong convective weather and are at high altitude, so there may be special bumps, so you must wear seat belts. If you don't wear your seat belt, you may be thrown out of the car with a sudden braking, which is very dangerous.

Because the plane, riding, are not stable, the road conditions are not good, at any time emergency braking must wear a seat belt, the plane has a take-off and landing need to fasten the seat belt, other unless special circumstances, after the take-off is stable, there is no need to wear a seat belt, the train has a special track, uniform speed, there is no emergency braking, so there is no seat belt.

Why don't trains have seat belts? Quite simply, the acceleration and deceleration of the train are relatively stable, and the speed is relatively stable during the middle of the journey, and there will be no sudden braking.

The speed of the train is relatively uniform and has good control, unlike cars and planes. The train also has a fixed track, which can ensure its smooth operation, its own performance, technology, are enough to support its smooth operation, and passengers do not need seat belts.

The train is relatively safe to travel on the tracks, and if the train derails, the accident is very serious, and the seat belt will not solve the problem.

Because it's not necessary, and it doesn't involve crashing and braking.

Why are there no seatbelts on high-speed rail?

Trains don't have seat belts because passengers are more likely to be injured when they are tied to their seats in the event of a major accident on the train. This is mainly because passengers who are restrained in their seats by seat belts are more susceptible to injuries caused by the collapse of the cabin structure, as they are unable to effectively dodge.

A seat belt is a safety part used on equipment, a safety part used to ensure safety when riding in an aircraft such as an airplane, or when working at high altitude to correct the liquid and perform a technical performance. The main raw materials are polyester, polypropylene, nylon. Seat belts not only refer to webbing, in addition to webbing, seat belts are also made of other parts that are easy to assemble.

1. High-speed rail has extremely strict control over stability.

A passenger once tested that during the acceleration of the train from standstill to 300 kilometers per hour on the Beijing-Shanghai high-speed railway, a cigarette standing on the small table of the train actually stood still.

2. The ballastless track used by the high-speed rail strictly controls the smoothness of the track.

It ensures that the train cannot have large lateral and vertical vibrations. So under normal circumstances, you can walk freely on the train without having to fix yourself in your seat all the time.

3. In the event of an accident on a high-speed train, the injury given to passengers by the seat belt is far greater than the potential protection.

When a major accident occurs in a train, passengers who are tied to their seats are more likely to be injured, mainly because passengers who are restrained in their seats are more susceptible to injuries caused by the collapse of the carriage structure.

4. The safety seats on the train are more effective.

Some studies have concluded that improving the design of seats on high-speed rail can effectively ensure the safety of passengers. The seat commonly used in high-speed rail trains in various countries is an "anti-collision" safety seat, which is designed to ensure that when the head or knee of the rear passenger hits the back of the seat forward, the seat can collapse and deform in time to prevent the passenger from being stuck.

5. For practical reasons, it is difficult to operate in practice, because people who take high-speed rail are unwilling to wear seat belts.

One of the important reasons why people choose high-speed rail over airplanes is that high-speed rail is spacious and runs smoothly, and people are used to moving freely in the carriage, so few people are willing to take high-speed rail and wear seat belts.

1. The stability of the EMU is excellent, and the probability of an accident before the sudden concession is very small, so there is no seat belt, and the seat of the EMU is specially designed.

2. The EMU has a special running track, which has strict control over acceleration and deceleration, which can ensure the stability of longitudinal movement.

3. When taking the bullet train, passengers do not need to fix themselves on the seats, they can move freely in the carriage, and the situation of unexpected situations in the bullet train will hardly occur, so there is no need to restrain passengers with seat belts.

The main purpose of the <> seat belt is to fix the passenger in the seat, when the vehicle is violently impacted, the seat belt can not let the passenger out of the seat or fly out of the window The high-speed rail does not have a seat belt for several reasons, the first high-speed rail speed is too fast, the role of the seat belt is relatively small, the speed of the general car is 120km h, and the speed of the high-speed rail can reach a virtual width of 360km h, which is 3 times that of the car. At this speed, the seat belt cannot resist such a large pulling force, but because the interaction of forces can cause harm to the human body. In addition, compared with China, some developed countries in Europe and the United States for the application of high-speed rail many years earlier than us, in 1988, Germany had the world's most tragic high-speed rail accident so far, when a high-speed high-speed train off the track, eventually resulting in 101 deaths, 88 serious injuries.

This is mainly because passengers who are restrained in their seats by seat belts are more susceptible to injuries caused by the collapse of the cabin structure because they are unable to dodge effectively.

Finally, because the cost of a high-speed rail is much higher than that of ordinary cars, even if it is some luxury cars, compared to high-speed rail is still a drop in the bucket, we take China's high-speed rail as an example, according to existing data, the cost of a high-speed rail train with a speed of 350 kilometers per hour is about 200 million Under this high cost, most of the seats of high-speed rail use anti-collision seats, which can collapse and deform when the head or knee of the rear passenger hits the back of the seat forward, preventing the passenger from being stuck, and the ** of ordinary family cars is only more than 100,000, Not to mention the installation of such chairs. There are no seat belts on high-speed rail, which seems to be an international practice, first because of high-speed rail. The accident rate is very low.

In addition, because the high-speed rail is relatively stable and spacious. People are smiling when they take the high-speed train. In fact, it's a bit like being at home or in the office, he needs to exercise and fasten his seat belt, and he can't reflect the spaciousness, stability and comfort of the high-speed rail.

So, I guess it's the international practice of abandoning the design of wearing seat belts.

Because the train is very smooth, there will be no major vibrations or bumps, and even in the train car, water bottles and coins can be upside down. There will be no sudden lane change during the high-speed train, resulting in sharp acceleration or sudden braking. Therefore, there is no need for a good bridge and a seat belt. Friendship is fierce.

Because the speed of high-speed rail is very fast, it is useless to have seat belts, and high-speed rail is very safe, and there will be no vibration in the body of the car when braking in an emergency.

Because the high-speed rail runs very smoothly and can ensure the safety of the high-speed rail, the high-speed rail is not designed with seat belts.

The speed of high-speed rail is fast, and the structure of high-speed rail vehicles is very strong, so in order for people to enjoy comfort, there is no way to install seat belts.

In our daily life, there are many ways for us to travel, we can choose according to our own economic conditions and the concept of time, the way to travel is buses, trains, high-speed rail, airplanes, etc., the faster is high-speed rail and airplanes, whether it is self-driving, buses, or airplanes, there are seat belts on them, only high-speed rail and trains do not have seat belts. So there are no seat belts on high-speed rail, what is the function of seat belts? Everyone knows that the high-speed rail is running on the rails, the heaviest thing is stability and safety, and there will be no bumps on the way, and the seat design of the high-speed rail is also very good.

One. High-speed rail focuses on stability and safety.

Everyone knows that high-speed rail and trains travel on rails, most of the roads are straight, there are hardly any major changes, and it will be much safer to drive on rails. There is no seat belt on the high-speed rail, with a seat belt, it may be more dangerous, because when an accident occurs on the high-speed rail, the items on it fall down, and it is inconvenient to move with a seat belt, and it is even more inconvenient to escape, without a seat belt, it will be much safer, and now the high-speed rail is very safe, there is almost no bumpy feeling along the way, it is very stable, you can walk around in the carriage at will, it is very safe, you can rest assured, do not wear a seat belt, it is also very safe for us. <>

Two. The track of the high-speed rail is well designed, and there are few accidents.

You don't have to worry too much, don't wear seat belts on high-speed rail, and other ways to ride in this safe situation, because accidents may occur in the process of driving the bus, because the bus is flexible, according to the road conditions, the plane in the encounter of long convection or some changes, bumps may occur, get up and land, the feeling of bumps will be great, and it will be safer to wear a seat belt. <>

The above is just a personal opinion, why don't you wear a seatbelt on high-speed rail?

There are no seat belts on high-speed rail because high-speed trains run very smoothly and do not experience large lateral or vertical vibrations, so there is no need to use seat belts; In addition, the high-speed rail has its own safety system, in the event of a major accident, the specially designed safety seat will quickly deform to protect the personal safety of passengers, and will not jam passengers, compared with the seat belt that may bind passengers and affect escape, the protection factor of the safety seat is higher.

Seat belts can play a restraining role, and can also play a cushioning role, and in the event of a car accident, can reduce the degree of injury to the driver and passengers, for the safety of the driver and passengers, and can also prevent the passenger from hitting the windshield due to inertia.

The function of the seat belt is to protect the safety of the people in the car, after being hit, it will not fly out of the car, and the seat belt will fix the person in the seat.

The function of the seat belt is that when the car brakes urgently, the seat belt will be tightened instantly, which can fix the person on the seat and avoid a secondary collision.

The function of the seat belt is to ensure the personal safety of people, and can play a buffering role in the event of an accident to reduce the injury of the accident to people.
