Understanding the structure of a motorcycle helmet is essential for a motorcyclist. This is because you need to know how it would protect you while driving on the road. You must also know how the parts function to keep you safe. Another reason for this is that in case your helmet is not working properly, you can know which part needs to be replaced. The helmet parts are available in some motorcycle shops with different brands and designs.
Motorcycle helmet parts are made from the highest quality materials. The most durable material that is used for motorcycle helmet is the carbon fiber. The materials and the construction applied for a motorcycle helmet must meet the standards of Department of Transportation (DOT), Snell, and the ECE. This is to ensure that these helmets can really protect your head from an accident.
The Motorcycle Helmet Basics
The four main components of the motorcycle helmet are as follows:
The outer shell is designed rigidly to absorb and disseminate kinetic force of the impact. It gives penetration protection thus keeping your brain safe. It is made from casted Acrylonitrile Butadiene Styrene materials. These include carbon fiber, Kevlar, and fiberglass.
The EPS or the Expanded Polystyrene liner lies underneath the shell. It also absorbs the kinetic forces of the impact in case the impact cannot be endured by the outer shell. The EPS liner fills the area between the rider’s head and the foam layer. These provide a comfortable fit.
The Retention System
The retention system of the motorcycle helmet is also known as the chin straps. These parts keep the helmet secures on the rider’s head. They are made from nylon. And they are placed from the ear cups of the helmet. The chin straps are bolted into the outer shell of the helmet which provides a strong foundation. There are also D-shaped metal fastening rings that are sewn to the left chin strap. Then the right chin strap passes on both rings then encircle it over the first ring to fasten the helmet onto the riders head.
The EPS foam layer is covered by a padded comfort liner that is made from leather or cloth. This also provides safety. The foam layer also gives areas for the rider’s ears and paths for the air of the helmet.
Other Helmet Parts
Helmet Face Shields and Visors
One of the essential parts of the motorcycle helmet is the face shield or a visor. This protects the rider’s face and eyes from the flying rubbish. It is made from polycarbonate plastics. It may be colored, tinted, or clear. For open-face helmets, the snap button mounting system is used that allow a clear face shield or a sun visor to be attached easily into the motorcycle helmet.
Ventilation is needed inside a motorcycle helmet. Manufacturers provide air vents so air can pass into the helmet and around the rider’s head. The air vents must be located at the top of the head. The air vents of the open-face helmets are placed on the forehead. It can be closed or opened. On the other hand, the full-face helmets have air duct that is located in front of the chin bar. Modern helmets have air vents that are put on the face shield, on top of the helmet, or on the sides of the chin bar.
Helmet Cheek Pads
A motorcycle helmet has right and left cheek pads. They come in different sizes depending on the size of the outer shell. Cheek pads must fit comfortably onto your head. Be sure that the cheek pads of your helmet touch your cheeks. However, they must not be pressed uncomfortably.
There are other parts of the motorcycle helmet. They are as follows:
- Eye Port Gasket
- Breath Deflector
- Super vent
- Mouth Vent
- Pro Shield
- Double “D” Ring
- Rear Vent
