What kind of motorcycle helmet is safe?
We've seen a lot of "civilian" helmets tested video, with hammers and bullets, but these videos are mostly for entertainment, and their accuracy is unreliable, telling you how bad a bad helmet can get.
So how exactly do you check the safety of motorcycle helmets?
Motorcycle helmets have different safety rating standards in different countries and regions, such as ECE in Europe, DOT in the United States and JIS in Japan. China also introduced a new 3C helmet certification system last year.Generally speaking, the safety of helmets can only be guaranteed if they meet the national standards and pass the inspection of professional institutions.
The main purpose of helmets is to protect the head of motorcyclists when they are hit, to mitigate injuries and even to save their lives. Helmets are important riding safety equipment!There are many kinds of helmets on the market. Today, we will talk to motorcycle drivers about how to choose the right helmet among various kinds of helmets, and how we can better protect each other's helmet types with love helmets. The half helmet only covers our skycap, which is light but poor in protection.Basically only suitable for very slow cycling.
Helmet: open helmet, with no face protection or only one windshield (goggles), many knights who play vintage cars will choose 3/4 helmet.The advantage is that there is a fan, the disadvantage is not enough protection, because motorcycle accidents have 30 percent will fall to the chin.
Full helmet: is often seen in movies, MotoGP events...Cool helmet!In addition to the Fullface helmets commonly seen in the above picture, the helmets also include the following three subcategories：
Cross-country helmet: the chin protection is enhanced based on the full-face type, and there is a hood on the forehead to keep out dust and sunlight, so additional goggles are required.
Pull helmet: pull helmet is similar to the off-road helmet, the lower jaw design will be somewhat convergent, and the helmet lens will be equipped.
Uncovered helmet: at low speed, the partially raised mask can breathe freely, and the whole face is closed, because the structure of uncovered helmet will affect the protection of the helmet to some extent.
Helmet selection from the far right, that is the result of wearing a half helmet when falling!In the event of a situation, half helmet than you are more afraid of death, will run!As for 3/4 helmet, although it can be worn properly, 3/4 helmet will still be on duty, but it can't provide protection around the chin. When you fall off a car, you will 'throw yourself on the street' directly. It is very painful for your chin to grind to the asphalt road.Only the full helmet on the far left provides effective and complete protection!
Drivers often see 'DOT' or 'SNELL' on the back of their helmets. These are considered helmet safety certificates.
Useful life: when buying a helmet, make sure you have the relevant certification. In addition, remember to pay attention to the useful life of the helmet, which is usually 3-5 years (the useful life of the helmet varies with different materials).If the helmet is not damaged by external force, the internal buffer material has been deformed and cannot provide effective protection, please do not use it again.
Ventilation: helmet after the actual wind tunnel test, the actual utility will be on the market.Some manufacturers have mirror defogging designs, such as the Free Flow System, which integrates the opening above the lens, the jaw opening and the neck Flow guide plate design. When the jaw opening is opened, the mirror fog can be removed successfully, greatly improving the defogging efficiency.
Lens: the high quality lens adopts the safety design, not only is not easy to break, and will never break, that is to say, no matter how twisted and bent impact, is cracked will not be broken.There is no need to worry about being cut by broken pieces, and the lens itself is formed in 3D, which is not very thick, so the image dispersion is almost non-existent.
Lining: each helmet pursues a comfortable lining, usually including the main pad above the head, and the ear pads on both sides of the ears.A good lining not only helps the head and helmet fit together, but also, more importantly, absorbs shock.Most good helmets have a dirty lining that can be removed and washed, and can be bought and replaced in different thicknesses to achieve a helmet that really fits your face.
