Suspension System: The intricate webbing inside the helmet is not just for comfort. It creates a critical standoff distance between the shell and the skull. Upon impact or a blast, this space allows for energy dispersion and reduces the direct transmission of force to the head.
Padding & Energy Absorption: The pads attached to the suspension system are made from advanced foam materials designed to absorb and dissipate kinetic energy. They compress upon impact, slowing down the deceleration of the head and reducing the risk of brain trauma, including Concussion or Traumatic Brain Injury (TBI).
Shell Geometry: The rounded, smooth shape of modern helmets is designed to deflect blasts and projectiles. This geometry helps to redirect the force of an overpressure wave around the head, rather than allowing it to strike the surface directly.
Extended Coverage: Newer helmet designs, like the U.S. Army's IHPS, offer increased coverage at the back and sides of the head, as well as mandible protection, safeguarding a larger area from blast effects and secondary impacts.
