In the ranking of the importance of motorcycle protective equipment, helmets definitely rank first. Some people may think that riding in the urban area or going to the vegetable market to buy vegetables is a short journey and the road conditions are familiar, so they can not wear helmets. In fact, this is wrong. As a knight, we must wear helmets as long as we ride!
1、 The correct way to wear
This phenomenon often occurs when wearing full helmets or bareheaded helmets. Sometimes we will observe that when some people wear helmets, they feel like pulling out carrots, going straight up and down. What's more, when wearing the helmet, it is very clumsy, and even the pull ring is stuck in the helmet, or even squeezed into the face! Don't think this is a joke. Xiao Bian has really seen such "players"! Some people even fold up their ears. It's strange that they don't feel uncomfortable!
The correct way to wear this type of helmet is to grasp the pull ring of the helmet with both hands, and then wear it from back to front, that is, press down from the occipital bone. If you still feel uncomfortable, Xiao Bian suggests that you put a magic towel or mask on your head before wearing a helmet, and then wear a helmet. In this way, it is easy to enter or exit, and the ears and face are more comfortable after wearing the helmet!
2、 Correct size selection
If the helmet is too large, its protective effect on the head will decline or even disappear. The helmet is too small, which makes people uncomfortable after wearing it, and it will make people headache after wearing it for a long time! So, how to choose a helmet that fits you?
Here we should know that helmets also have a size chart, and only some fake helmets or inferior helmets will have the same size! First, we need to find a tape measure, and then circle around the circumference of the largest part of our head, usually the eyebrows. Then record the size, and use this size to compare with the size chart of the helmet to choose a helmet that fits your size! Usually, after wearing the helmet, we should first move the helmet from left to right, and aim our ears behind the ear of the helmet. If the skull part is not wearing a helmet, then this helmet is suitable for you! If the skull is too tight, the head will ache after wearing it for a long time!
3、 Function of helmet duct
Under normal circumstances, the helmet usually has three air ducts. Some friends may simply think that the air duct only serves as ventilation! In fact, the air duct has three functions, namely, demisting, noise reduction, and ventilation!
Defogging: First, the air duct of the helmet has a defogging effect. Although the defogging effect is not obvious, we also need to know how to use it. To use the air duct for demisting, open the front air duct, the top air duct and close the rear air duct. After the operation, the rapidly rising airflow can effectively remove the fog on the lens!
Noise reduction: as the name implies, it means to keep quiet. To achieve noise reduction and mute, close all three air ducts, or just open the rear air duct. Some helmets are very quiet after all the wind tunnels are closed!
Ventilation: If you want to have good ventilation inside the helmet, you need to open the front and rear air ducts and close the top air ducts. This is the same as the ventilation effect in our room! However, in this case, the interior of the helmet will be noisy!
As the saying goes, you can't have both fish and bear's paw. If you want good ventilation, you must sacrifice silence! If you want to be quiet, the feeling of stuffiness will come!
