Cycling helmets: species and choice

Cycling helmets: species and choice

Mobile around the bike is becoming more and more popular. To protect the cyclist from injuries with a possible fall there is a special equipment, and the helmet is one of the important attributes.

Description and device

Adult male and women’s vocations in principle do not differ at least and are determined by their appointment. Appointment of a bicycle helmet – Head protection from injury when falling. Protective quality helmets are based on the principle of operation described below.

The main strength of the strike obtained during the fall, assumes the outer sheath of helmets, and the blow to a certain extent is softened by the inner polystyrene layer of the case.

Then, to a lesser extent, the load through the layer affects the head of the person. Thus, Voshlem distributes shock power throughout the head, protecting her skin from the Russian Academy of Sciences and Absadin.

This principle is provided by a special design.

A biker helmet includes a number of elements.

Frame

Polystyrene foam and polyurethane foam material. Expanded polystyrene foam at first, and then restored in the form. It is characterized by low weight and high ecology. Polyurethane Foam reminds usual foam.

To enhance the protective effect, some models are strengthened with nylon or carbon fibers.

Shell

Case Caski outside covered with plastic shell. Sheath allows you to distribute shock power. In addition, it protects the body from damage, punctures and cracks, and also capable of sliding on the ground after the fall of the cyclist. This ability reduces the risk of hazardous damage to the neck and head.

Fixing elements

Veloshlem is fixed using these elements:

  • Rememkov – They are designed for fastening helmets on the head+
  • Head Volume Controller – It is located in the occipital part of the helmet and coordinates the degree of tightening using a special disk or runner.

Holes for ventilation

They are needed to access fresh air to the head and prevent overheating.

Additional attributes of the helmet are visor and mosquito net, which create greater comfort for a cyclist. Some experienced highway attachments also attach to the viscosle Rearview mirror, What makes it easier to drive in dense traffic.

There are 2 types of bicycle helmets – Hardshell and In-Mold.

They possess the same protective properties, but have some differences in the method of manufacture.

Type helmet Hardshell It is a 2-layer design consisting of an internal foamed layer capable of amortizing the blows, and the outer layer of high-strength plastic. The weight of such a helmet is quite large, but it has a higher degree of reliability.

Cascading type In-Mold – This is a solid design of a shock-absorbing foam and a thin outdoor layer. Weight of such a helmet is relatively small and he has good ventilation. It increases comfort when wearing it and reduces the pressure on the neck. But the external coating does not have sufficient strength.

Primary requirements

The main and main requirement for the Slem is the maximum security provision. To guarantee the protective properties of the helmets tested by depreciation when hitting, damage resistance to cutting items, the strength of the head of the head by locking belts, the quality of the fastener system, is monitored by visibility overview – It should not be less than 105 degrees.

In Europe and the United States, there are standard impairment rates. Therefore, import helmets must have a factory labeling and a mark on passing acceptance.

In addition, helmets should have good aerodynamic properties, which is achieved due to the form, size and general type. These properties reduce resistance during a ride, which is especially important for cyclists-athletes.

Other equally important requirements are Convenience when wearing, ease of helmets, aeration. Reflective sticker is also needed, it is fixed on the occipital piece of helmets. Such an element, reflected in the sun or in the light of the headlight, draws the attention of other drivers and improves traffic safety on the motorway.

Varieties

There are several types of helmets. First of all, a variety is determined by the manner and style of cycling.

Cross Country (Amateur)

Such helmets are suitable for newcomers and amateurs of outdoor activities, for cycling and driving on the highway. They cover the top of the head, leaving the whiskey and the heads open open, are equipped with a large number of aeration holes that provide good ventilation. Often complemented by a sunscreen visor.

However, this is a disposable helmet. If the blow during falling is quite strong, then its inner part is damaged and makes it unsuitable for use.

Highway or racing

They are considered the easiest weight and applied by professional athletes. According to its design, they are similar to cross-crate, but differ in better ventilation due to holes are somewhat larger, good aerodynamic properties and a sufficient overview. The visor is absent.

Kotelok

This species is used by athletes in special bicycles type VMK (Street, Dertt). For the manufacture of such helmets is used thicker and durable plastic. Aerial holes are absent. Protective properties The bowler is higher, but also weight is much larger.

Fulfeis

Used cyclists who prefer such extreme ride styles like Freeride, Downhill. This is a closed helmet, which protects the head and face, and the neck. It usually happens with a fastened visor (or with glasses), protecting eyes from foreign particles.

For the manufacture, high-strength materials such as carbon and fiberglass are used, which are not damaging even with very strong impact.

Track

This species is applied by athletes in racing on cycle shops. The streamlined shape and lack of ventilation reduces resistance when driving and enhances aerodynamics.

Aerodynamic

    Such helmets are intended exclusively for high-speed ring and cycline racing. Their boobs form contributes to an increase in aerodynamic properties. They have a fairly large weight and fewer air vents.

    Voshlem for mountain bike

    They differ in a solid fixation system, a stronger outer layer.

    Men’s and female helmets can differ only by hole for fixing hair on the occipital part, designer performance and colors.

    Except adults exist and Baby helmets. These are usually universal amateur types, the size of which does not exceed 45-57 cm, intended for children from 2 to 12 years. In children’s bowlers, aeration holes are somewhat less. It is lighter by weight, and the inner gasket layer is much softer.

    Dimensions

    Usually the size of the helmet is indicated by the manufacturer in the alphabet. To determine your size, It is necessary to correctly measure the scope. It is measured along the line passing over the eyebrows (above 2 cm) and through the occipital, most protruding, part of the head.

    The result obtained can be verified in the table:

    Scalp in cm Size Caski
    51-52 Xxs
    53-54 Xs
    55-56 S
    57-58 M
    59-60 L
    61-62 XL
    63-64 Xxl
    65-66 Xxxl

    However, even knowing its size, before buying a helmet it is better to try it.

    The rating of models of different types of caskens showed that the best and most popular models of brands GIRO, CASCO and FOX.

    The best representatives of the GIRO brand are Voshlem Models Giro Synthe and Giro Foray MIPS.

    • Model Synthe refers to the aerodynamic highway casak. She connected such positive characteristic features as low weight (only 223 g), comfort provided by excellent aeration, and good aerodynamic properties.

    • Helmet Case due to use air system Roc Loc It has a slightly raised form, which makes it very convenient for almost every person. According to the manufacturer, the ventilation abilities of the helmet are so high at any speed, which are superior to other models of the line.

    Aerodynamic characteristics are also characterized by the highest indicators.

    • Model Foray It has original design. The streamlined shape of the helmets, narrowed in the occipital part, is convenient for any position of the head.

    The increased strength of the helmet is ensured by the fact that the outer shell and the internal foam layer are connected to one solid layer.

    The helmet is equipped with a system of protection against blows of different directions, which guarantees a very high degree of reliability. Additional stacks of foam rubber create comfort when wearing. The ventilation system includes 5 channels by which the air applies over the entire surface of the head, even at low speed. The model is equipped with a size adjustment mechanism.

    • Company Casco also represented by several models. Casco Speedairo – Helmet, designed to drive at high speeds. Different with reliability and high security. Excellent ventilation is provided by internal air layers and ventilation holes, excluding overheating and supercooling.

The model is also equipped with a CASCO Loc control system, a visor, whose height can be changed, the mechanism for adjusting the size and landing, mosquito net. Increased safety at night is guaranteed by the presence of reflective labeling.

    • Full-Face Voshlems are represented by the FOX brand. Model FOX Rampage Pro Carbon considered the best of the entire brand line. It combines all new technical and design achievements.

    Consider the advantages of this model.

    1. The outer shell is made of high-strength carbon, at the same time having a small weight. The hardness of the whole design gives reinforced jaw.
    2. The use of an additional innovative security system of the MYPS, which is that the inner layer of helmets is attached to the outer sheath in such a way that it can slide according to it due to the fine gasket from special tissue, which reduces the risk of injury at the accident.
    3. Aeratorial system includes 17 holes that are located almost throughout the surface of the helmets.
    4. The inner layer is made of materials with climate control function. They are able to quickly absorb sweat and quickly dry, the air is well passed and have antibacterial properties.
    5. Reliable fixation is guaranteed by fasteners with a double ring in the shape of the letter D.
    6. The design is characterized by brightness and variety of paints with matte or brilliant coating.

    However, the weight of this model is very large – about 1.24 kg for size M.

    How to choose?

    When choosing a helmet, you need to take into account many nuances.

    • The size. Properly selected size guarantees not only comfort, but also safety, so when buying a helmet should be done. Models with adjustable size Customized individually. The feeling of discomfort – reason to try on another model.

    • Landing Voshlem. Nutya helmet and fastening belts, you should check your feelings: helmet should not sit very freely or, on the contrary, tightly and put on the head. Strap and edges should not crash into the skin. When the head is moving, it is permissible a small deviation of the model to the sides, but it should not crawl on the neck or forehead. With proper planting, the helmet occupies a horizontal position, covering the forehead and the back.

    • Fixation. The best option if the clasp is passed through the top surface of the case and attached to it. This is more reliable. Belts fixed on side surfaces do not guarantee reliable fixation, and helmet can fly when falling. Clasp must be unborn with one hand.

    • Ventilation. It should be remembered that the ventilation is better if the holes in the hard hat.

    • Cask weight also need to be considered. Heavy models have a great pressure on the neck, so it is preferable to choose light models, although they are more expensive.

    • Safety. Helmets with Marking CE EN 1078 (European Security Certificate) have a high degree of security. This means that the model has been tested by a number of tests.

    • Quality. It is necessary to check the condition of the inner layer and the outer shell. They should not have no cracks, nor dents, no other defects.

    • Comfort. For greater comfort, many models have an inner lining that absorbs sweat and displays it out. In the best models, these lining are removable, and they can be washed.

    • Colour. Usually cyclists choose a helmet under the color of their form. However, it is desirable that the coloring is bright, and therefore more noticeable other drivers. If night trips are possible, it is recommended to buy helmets with reflective elements or a small shimmering flashlight.

    Preferably buy helmets With size adjustment. This will allow in the cold time to wear a premium, weakening the straps.

    Terms of Use

    In some countries, it is obligatory for a cyclist, and there is a fine for riding without it. In our country in traffic rules, it is not provided, and you can ride without helmets, but personal safety requires its wearing.

    There are certain rules for using a helmet. After buying, you first need to explore the instructions for the Slem and perform it clearly to guarantee the safety.

    The main and most important rule – helmet must be put on even in the shortest trip.

    It is also important to wear it right well and secure fasteners. The helmet is needed only for personal use, and it is impossible to borrow it to someone, or use someone else’s.

    After falling and getting a blow, the helmet must be replaced, even if there are no visible damage, as cracks can be internal and invisible. It is also recommended to change the helmet in 4-5 years, even in the absence of accidents.

    Keep hardware needed in a cool darkened and dry room. Wash with warm water with a rag napkin without the use of cleaning products.
