Abstract
A protective headgear can include a core and two or more impact absorbing layers coupled to the core. At least one impact absorbing layer can include a number of impact absorbing components that are configured to absorb and reduce the force of impact incident on the protective headgear. The impact absorbing materials can employ cylindrical segments of viscoelastic foam with a sealed central void to absorb high energy impacts. The protective helmet can reduce the occurrence of concussions and subconcussive impacts to the brain.
Claims16
A protective headgear comprising:
- a rigid core;
- and
- a plurality of impact absorbing layers disposed on the rigid core and configured to absorb impact incident on the protective headgear;
- said plurality of impact absorbing layers comprising an inner layer and an outer layer disposed directly on opposed sides of said rigid core;
- wherein at least one of said impact absorbing layers comprises a plurality of impact absorbing components;
- wherein the impact absorbing components comprise conical elements each having an internal cylindrical void;
- wherein at least one of said impact absorbing components further comprises a barrier fixed to a distal end thereof such that said at least one of said impact absorbing components is fixed to the rigid core at a proximal end thereof and fixed to said barrier at said distal end;
- and
- wherein the barrier is configured to prevent the passage of air.
