NOVELTY - The helmet has a shell made of durable and impact absorbent material, and provided with brightly colored, shiny, dirt and peel resistant coating. A buffered layer is made of impact absorbent and harmless material to cover a protection zone of head. The buffered layer is stuck with a padding made of durable, perspiration absorbent, air permeable and harmless material. The light transmission rate of visor is greater than 85. The extensibility of belt is less than 25. The acceleration peak value is less than 300g and reaction time when acceleration exceeds 150g is less than 4ms.    USE - Solar powered fluorescent motorcycle helmet.    ADVANTAGE - The shell is manufactured such that it does not crack during test, and the protective function of shell is not compromised even after the removable components are dismantled. The head and neck are not hurt during impact, by providing the padding. The penetration of iron drill into the helmet is prevented by the anti penetration effect of the helmet. The helmet can be placed on the back seat or rear box of vehicle to see the breakdown of vehicle on the road at night, so the traffic accidents can be avoided. The helmet is effective in keeping the motorists alert to avoid knocking motorcyclists down, even if the headlights and tail lights of the motorcycles are dim or spoilt. The helmet can send clear signal to the public road users and pedestrians and keep them alert to effectively prevent accidents. The brightness of the helmet can prevent young motorcyclists engaging in illegal racing or speeding with the headlights and tail lights off at night while preventing motorcyclists escaping from law and authorities.    DETAILED DESCRIPTION - The exposed height of visor joints is less 7, the exposed height of belt and other joints is less than 3, and the radius of vents on the shell is less than 13. The mass of entire helmet including the accessories is less than 1.60. The left, upper, right and lower visual fields are greater than 105, 7, 105 and 30, respectively.    DESCRIPTION OF DRAWING(S) - The drawing shows a side view of the solar powered fluorescent motorcycle helmet.
