Motorcycle helmet There is no doubt about the function of protecting cyclists' lives. According to the report of the American Highway Safety Insurance Research, in 1999, 98% of the deaths on bicycles in the United States did not wear helmets, and those who wore helmets in collision accidents reduced the risk factor of serious head injuries by 85%. In addition, wearing helmets not only makes people feel cool, but also really cool. At the same time, the air vent on the helmet can make the head feel cooler. As an old saying goes, a clear mind is more likely to win the competition.
China is a major motorcycle producer, with an annual output of more than 10 million and a motorcycle population of about 40 million. It is reported that since the late 1980s, the number of traffic accident deaths in China has ranked first in the world for 10 consecutive years. From the perspective of motorcycle casualties, most of them are caused by wearing inferior helmets and incorrect helmets.
How to choose helmet correctly
Since the introduction of a set of quality inspection equipment for motorcycle helmets costs at least one million yuan or even tens of millions of yuan, and most places cannot afford to purchase it, the quality of motorcycle helmets can only be inspected by one or two designated quality inspection departments, which has caused a management vacuum in helmet sales. In addition to consciously abiding by traffic rules and correctly wearing motorcycle helmets, motorcycle riders should also strengthen their awareness of safeguarding their rights and not buy or use low-quality fake motorcycle helmets for their own safety and family safety. The following is a simple identification method for motorcycle helmets:
1) The shell shall be made of hard, durable materials that can absorb more impact energy; The buffer layer shall be made of non-toxic and harmless materials that can absorb more collision energy and cover the head protection area; The pad is made of sweat absorbing, breathable and other materials; Wear the device to ensure that the helmet is firmly in contact with the head; The goggles are made of materials that meet the light transmission performance and impact force, and the light transmission rate is not less than 85%.
2) Weight requirements of helmet: full helmet<1.6kg, half helmet<1.3kg, left and right horizontal vision>105 °, upper vision>7 °.
3) The helmet must have fixed signs, such as product name, manufacturer name and address, trademark, product type, product model, specification, production date, product batch number or serial number.
4) Helmets can be divided into three sizes according to the head circumference: large 580~600mm, medium 560~580mm, and small 540~560mm. When choosing helmets, you must choose the appropriate number according to your head circumference.
5) The helmet should not be used after a major collision accident.
When choosing a helmet, you should also pay attention to holding both sides of the helmet with your left and right hands, and then rub your head up from left to right. When taking off the helmet, on the contrary, shake it from side to side after putting on the helmet to see if it is appropriate in size. The tightness is subject to no pinching or shaking. When measuring the weight of the helmet, you can't use your hands. The correct way is to use your head after wearing it. If your neck doesn't feel heavy, it's OK.
