Helmets are mandatory for motorcyclists, but many people still have the wrong idea about it and damage its use. This article will introduce some questions related to all aspects of helmet.
Why Should We Wear A Helmet?
Motorbike, cycling, skiing, rollerblading or any other activity related to the high-speed movement have the same characteristics that the head is not shielded, and protected, which leads to risk of severe head injury, even the risk of death. Wearing a helmet is the best way to minimize trauma to the head of the driver.
A qualified helmet usually includes 4 layers: outer crust, bearing layer, chin lock and adjacent to the first liner. Outer crust is capable of dispersing power, which prevents outside objects from entering the helmet. Bearing inner layer is usually made of EPS (Styrofoam indent) or similar material, which have the ability to absorb impact energy by breaking out. Lock chin and fixed lining helps to put the motorcycle helmet in a correct position.
When riders fall or get collision, the force of impact to the head is moving, which will be distributed evenly peel caps, and absorbed into the inner bearing cap layer, then reduce the forces on the head. Typically, dependence and speed of movement of the head (the speed of the person), and the size, weight and motion of the greater impact are bigger, the force of impact will be surely stronger. The process of shock and stop happen very quickly, within 1 microsecond, inside porous particles will absorb and break off, which do not seriously affect the head.
Can Helmets Be Used Forever?
No, the helmet should be replaced once 5 years. It is recommended by most manufacturers of helmets, and the rating agencies of the Snell helmet. Adhesives, plastics and other materials used in helmets can affect bearing layer. Hair balms, body sprays, and other cosmetics can also degrade the impact of the helmet. That’s not taking into account the external factors like other collisions, which can affect the quality of the helmet. That is why you should replace your helmet after 5 years of use, even though they have not fallen apart or are still beautiful.
Does It Need To Be Replaced Immediately After The Falling?
Usually,the answer is not, if you do not drop the helmet at a too high altitude, too many times or is moving at great speed.
How Can Helmet Fit Your Head?
Today all citizens wear motorcycle helmets when participating on the road, but few people know whether the helmet fits the head in accordance with the standards or not.
When buying a helmet, you necessarily should try to understand if it fit or not. To test whether there is too large or not, you should wear monitoring chin straps to place the right position.
To test cap, which is too small, you should wear a hat for at least 5 minutes then determine whether it has any pressure or feeling cramped up your head or not. If yes, you should choose the wider helmet. In addition, below are the ways parent should teach children how to wear the right helmet.
