Speaking of safety helmets
The first reaction of a "cycling friend" is
↓ ↓ ↓
"I have a big head and it's too tight to wear it"
"I just made air bangs, I don't want to wear them"
"I'm afraid of heat and don't want to wear it"
But not wearing a safety helmet, it's too late to regret an accident ! Faced with a wide variety of safety helmets with different functions, how should "cyclists" choose?
Common sense of helmet purchase
1. At present, the helmets on the market are mainly divided into full helmets, 3/4 half helmets, and 1/2 half helmets.
Full face helmet
It protects all parts of the head, including the chin, and is the best helmet for protection. However, this type of helmet has poor breathability, and is generally used less for non-motor vehicles. If you need to ride a motorcycle for a long time every day, you can consider this type of helmet. Of course, "helmet lovers" please feel free.
Three quarter helmet
This helmet protects three-quarters of the head. It takes into account both protection and breathability. It is a relatively common helmet. If you want good protection, but not too stuffy, choose it.
Half helmet
At present, the more common helmets on the road, because of its small size, light weight, and easy to wear, so most people choose it, but it cannot best guarantee the safety of drivers and passengers.
2. Check for protrusions on the inner and outer surfaces of the housing. The protrusion should not cause discomfort to the wearer when trying it on or feeling it with the hand. The surface of the shell shall be firm and smooth, the edges shall be rounded and blunt, and shall remain intact and free of cracks.
3. Check the strength of the wearing device. Correctly fasten the laces and fasten the buckles according to the instructions. Pull it hard, and there should be no slipping, tearing, tearing of the lace, falling off of the connecting piece, loosening or breaking of the buckle.
4. Check the goggles. If the helmet is equipped with goggles, the goggles should not have cracks, scratches and other appearance defects. Push the goggles to the highest position and they should be able to be positioned when released.
5. Check the buffer layer. Try on the helmet, the cushioning layer should not shift. Press hard on the buffer layer of the helmet with your fist, there should be a slight rebound, neither hard, nor out of pits or slag.
6. Select according to head circumference. Try it on yourself as much as possible, not too big or too small.
After buying the helmet, it is also very important to know how to use and wear it correctly.
