Motorcycle-related road traffic accidents account for 51% of the total each year, and motorcycle road traffic fatalities account for 63% of all road traffic fatalities. Therefore, you understand that motorcycles are a high-risk object and relatively poor in car accidents. Judging from the death and injury of motorcycle accidents, the fatality rate of warriors is 59.6%. In the absence of a helmet, the chance of a head injury is **.8%.
This person should be impressed by pictures from the past. This was also an unfortunate accident. The speed of the casualty accident was 70mph, about 112km/h, and the helmet rolled on the ground. If you use a fake helmet, the actual effect is the same as without the helmet.
Maybe you can say that riding a bicycle is so risky, so why ride a bicycle? This is not empty talk, then the chrysanthemum will burst when you poop, so why do you poop?
Therefore, everything is one. The motorcycle itself is not a risk. It is the problem of the driver and the operator. If you do not correct your psychology and thoughts and improve your professional skills, then I suggest you not to ride a bicycle.
Returning to the discussion of helmet safety, in terms of damage probability, no helmet is likely to cause 2.5 times the damage than wearing a helmet. At the critical strike level, the fatality rate without a helmet is 1.5 times that of wearing a helmet. If you see here, you still insist on riding a bicycle without a helmet, then for your daily life and your loved ones, you better give up riding a bicycle, it is not worth being a warrior, is it?
The helmet function of maintaining the central nervous system of the human brain.
The brain is encased in a liquid layer in the skull, giving it anti-tear properties. But when the oscillations go beyond the region the liquid can take, the bigger head is the hard skull. Just like the soy products we buy at the mall, people soak them in the water in the package to reduce vibration and thus protect the soy products from damage. Safety|A helmet where your life is valuable.
As you can imagine, the brain in the skull is in a state of rapid motion even though the rapid fitness movement of the skull is terminated or slowed down when the head hits an obstacle in rapid motion. The situation is like throwing soy products against a wall. The apparent level of adverse effects is evident. it will die!
How to maintain the life of the helmet.
The fatal head trauma is not the first impact on the helmet surface, but the second impact on the head and skull. The first shock occurs when the helmet hits an obstacle, and the second shock occurs when the head hits the skull. The head mechanism can be squeezed out or torn, causing permanent damage. Cerebral hemorrhage will increase the working pressure of the skull and destroy the head mechanism! If there is a frontal impact, the impact force will penetrate to the bottom of the skull at the same time, and the obvious impact will damage the spine and skull, breaking the inhalation and heart rate.
So now understand the need for helmets?
Because the fatal head trauma is not the first impact on the surface of the helmet, but the second impact on the head and skull. Thus, the function of the helmet is to reduce the rate at which the head hits the skull. The industry standard is accurately measured in G-values. The key verification requirements for helmet inspection are to place the controller in the helmet, drop the helmet from sharp metal materials from different relative heights, viewing angles and methods, and then verify that the helmet hits an obstacle and moves quickly throughout the movement. How big is the GForce inside the helmet when it stops functioning.
In addition to free fall, there is also continuity. Whether sharp objects will pass through the helmet; at the same time, there are also falling, deformation and bandages, which are all about whether the helmet is very easy to fall off, the helmet is deformed and the bandage is deformed.
