What is the purpose of the impact cap system in the structure helmet?

• A. To improve ventilation
• B. To increase overall weight
• C. To secure the visor
• D. To reduce shock transmission at the top of the head

Answer: (D)

Reducing shock transmission to the head during impact. The impact cap system acts as a deformable layer inside the helmet that compresses when the helmet strikes a surface. This compression absorbs part of the crash energy and helps distribute it more evenly, so the peak forces reaching the skull, especially at the top of the head, are lowered. That energy absorption is what protects the brain from high-G shocks and reduces the risk of head injuries.

Ventilation improvements aren’t the primary goal of the impact cap; altering airflow is not what this system is designed to optimize. Increasing the overall weight would be undesirable and not the purpose here. Securing the visor is handled by other components of the helmet’s assembly, not the impact cap.
