Types and use of helmets
Sometimes it's hard to pick the helmet than the bike itself. There are many different types, sizes and features. So how to choose ? Firstly , the rider must take into account the type of use that can be divided into : use within cities , on the road or playing sports on-road ( on asphalt floor ) and off road ( in land ) . For urban use , there are three types of helmets : full (fully closed) , open - which leaves exposed face and chin - and folding ( hinged ) . It is clear that the integral is safer because it offers greater protection , both in case of a fall , as the adversities of pathways, such as insects or stones thrown by other vehicles . The open is more comfortable on hot summer days , it leaves the face exposed to the wind , but it is mandatory to have visor ( like the others ) , or be used with goggles own protection for motorcycles . The retractable or hinged models combine the safety of a full face helmet , with the sense of freedom of the open helmet. However , in case of a strong impact, " chin guard " does not offer the same level of protection of the closed model .
The helmets are typically constructed basically of two types of materials : plastic compound injected or synthetic fibers. The hulls are constructed from are cheaper but offer less protection to the rider. The characteristic of the material causes the helmet hit the ground again and again - like a bouncing ball - what is known as end - spring, absorbing less impact. Since helmets made of synthetic fibers (fiberglass , carbon , Kevlar , etc. ) , and are manufactured in a smaller scale, offer greater capacity to absorb impact, as the material can be reconstituted more rapidly than plastic.
It is also important to note that Brazilian standards require a more enhanced protection in the region that corresponds to the skullcap , temples and neck . Therefore , open or only meet the standards helmets do not protect the chin region . So it is advisable to use a full face helmet on travel and roads , where the speed is higher . Vale also , that just does not wear the helmet , remember it should be well fastened . There are two types of locking : jugular strap with quick coupler system or double ring . The first is more practical , but is subject to wear and possible opening in the event of an accident . The second , lasts longer , provides more security but is more cumbersome to buckle and unbuckle . In either case , it is important to always keep well and buckled the strap touching the neck jugular pilot strap . If there is play , there is the possibility of the helmet fly off in an accident .
For sport or leisure use, both paved circuits , as the dirt tracks , we recommend the use of lighter helmets , usually made fiber , usually carbon or glass , and have purpose " Racing " . These models are usually more expensive , but offer safety in extreme conditions . For on-road use , there are models " racing" of integral type and for off-road use , there are helmets designed especially for this type of sport. Are devices with a front " flap " that protects against rocks and other adversities . These helmets also have no visor, however pilots using an exclusive glasses for this purpose, but offer greater space for the mouth of the pilot chin strap to facilitate ventilation and breathing.
measurements
But helmets should not only bring security , should be accommodating. For this it is necessary to know the extent of your head and keep in mind that as the shape of the braincase of each person is different from another , so are the helmets . So before you choose your , the biker should get a tape measure and measure the circumference of your head . The number listed in centimeters will correspond to the size of the helmet. Examples : 56 - Small , 58 - Medium , 60 - Large , 62 - Extra Large , 64 - Extra Extra Large.
Due to their different shapes of heads and helmets , worth trying before buying . The fact that we use a measure of a brand and model does not mean that this will be the same as for other manufacturers . When you taste it , the rider should be aware that the helmet wears well. Ie if it is comfortable both cheeks , as the front of the head. Let us be clear : Comfortable does not mean loose . The helmet needs to lean against the scalp and pads ( foam ) side cheeks . There can be no space between the helmet and head. When the foam and Styrofoam helmet is already spent, or already experiencing a gap between the driver's head , it's time to change . Broad helmets tend to come out of the head in case of accidents .
The cheap comes out expensive
The biker should be aware that the brain , although vital , is one of the most fragile organs of the body . Unfortunately , the head is the first part of the body to be impacted in the event of a fall or accident . Thus , the rider - and croup or - should not opt for the cheapest helmet in the market (not the most expensive ) , but for a reliable product for the type of use . To ensure that trust and quality to consumers in February 2001 and ABNT (Brazilian Technical Standards Association ) created the NBR 7471 . In addition to providing the dimensions and weight , the resolution also requires that all helmets sold in Brazil ( domestic or imported ) undergo quality testing , certified by INMETRO ( National Institute of Metrology , Quality and Technology ) . Remember that helmets bought abroad for personal use are within the law , since the seal is only awarded for helmets sold in the country as envisaged in Resolution No. 203 of the National Traffic Council ( CONTRAN ) , dated September 29, 2006 .
The tests are to assess the strength of various parts of the helmet, as the jugular band , the visor and the hull itself the shocks experienced at the top , sides, and also in the nuchal region. Therefore , when buying a new or your first - helmet, biker should check if the product has the seal INMETRO guarantee that the helmet was approved and passed all tests . According to Rodrigo Almeida , marketing manager of BR Motorsport - representative of AGV and LS2 - consumers should always check the originality of a helmet . " People can not deceive with very low prices . There are many counterfeit copies of helmets known as LS2 and AGV . On the parallel market , LS3 and find brands like AVG , which cost around £ 50 to £ 100. Such equipment does not pass through the test and still receive the counterfeit seal INMETRO . Who buys helmets in these conditions is playing with life , "he says .
Another factor that is fully connected to motorcyclist safety is the field of view offered by the helmet. If the visibility and peripheral vision is compromised by the hull shape , the probability of an accident happening increases exponentially.
No use buying a bike at $ 30,000 and go out riding with a helmet out of specification , or worse, fake . And this is very common . Often the rider believes that being " smart " to save the helmet. The cost can be very expensive ! ( Roberto Brandão Filho / INFOMOTO Agency )
