Which part of the helmet is designed to absorb impact energy?

The inner foam liner of a helmet is specifically designed to absorb impact energy. This foam material plays a critical role in reducing the forces transmitted to the head during a collision or fall. When an impact occurs, the foam compresses and dissipates the energy, thereby minimizing the risk of injury.

While the outer shell provides protection against penetration and can deflect objects, it is the inner liner that is primarily responsible for managing the impact energy. The suspension system helps keep the helmet in place on the head and can contribute to comfort, but it does not absorb impact energy directly. The chin strap secures the helmet to the wearer but also does not play a role in energy absorption. Therefore, the inner foam liner is the key component for safeguarding the helmet wearer upon impact.
