Bike Helmet Construction
It is important to understand the way a helmet is built in order to understand the often very different prices, styles, Certifications de sécurité et matériel utilisé. Bike helmets are made up of three main parts: a Shell, a Liner, and Straps.
Shell
The shell is your bike helmet’s outer layer—the part that people can see when you’re riding. It’s typically made from an impact-resistant plastic or composite and is designed to spread the force of an impact over a broader area, protecting your head in a crash.
Liner
The liner is located directly beneath the outer shell and does most of the work during a crash and is typically made from crushable or impact absorbing foam. During a crash, the liner absorbs the impact energy causing less of it to be transmitted to your noggin.
Straps
Made from nylon or polypropylene, straps keep your helmet attached to your head. Are your bike helmet straps fraying? It might be time to invest in a new helmet since your helmet can’t effectively protect you in a crash without a fully functioning closure system.
Construction Types
There are two main construction types for bike helmets, in-mold and hard shell.
