Know better about the helmet anatomy and its function

Helmet become one of the tools that must be used when we riding a motorcycle. Not because regulations require, but should be more on awareness of the safety of themselves.
Just like your head, a helmet has plenty of parts that need to work together to protect your brain. These are the things to look for. (Picture from: http://bit.ly/1Xe8DEM)
Helmet also consists of a number of parts, thus forming a complete helmet. As released by Cycleworld based on The Total Motorcycling Manual book, this is the anatomy of a helmet.

1. Protective visor has a duty to protect the eyes and face from the wind, heat up and dust. However, glass is also able to reduce wind noise that could disturb while riding.

2. Outer hard shell, made of various types of materials, from plastic, Kevlar, fiberglass to carbon fiber. If the shell is broken, then the parts underneath the helmet will be damaged and could head injury.

3. Impact absorbing liner, one part of the helmet that are not visible, the position sandwiched between the shell and the soft liner. Made of polystyrene or polypropylene (EPS), which has the task of reducing the impact energy. Never reuse the damaged liner.

4. Comfort liner, this is the part which is in contact with the skin and hair. This part is made of soft material and generally can be removed to be washed and cleaned.

5. Airflow vents, imagine if a helmet without air vents. Users will be uncomfortable, and sultry. The best ventilation design at three positions, namely at the front of the helmet near the mouth, above the eyebrows and the rear for the exit airflow.

6. Chin bar or chin protector present only in the full-face helmet type. That's why the full-face helmet can protect the entire facial area.

7. Retention system or strap, usually made of nylon rope. The fastening system are the quick buckle model, or the D-ring.

8. Helmet standardization, a quality helmet should display a sticker showing it’s been tested. In the United States, DOT is acceptable; Snell is generally viewed as better. In Europe, look for an ECE-certified lid. In Indonesia alone requires the SII standard outside the standards earlier. *** [EKA | FROM VARIOUS SOURCES | CYCLEWORLD]
