Problems solved by technology

The problem with this design is that as the hole size decreases and the energy dissipation increases, the time for energy dissipation also increases
As a result, the user may use a larger helmet, which is at the same time more comfortable and easier to wear, but does not provide the level of protection achievable with a properly fitted helmet

Abstract

The present invention is a protective helmet having multiple zones of protection suitable for use in construction work, athletic endeavors, and similar activities. The helmet includes a hard outer protective that is suspended over a hard anchor zone by elastic cords extending between an elastomeric zone between the outer and inner zones. Fluid filed bladders are positioned in the elastomeric zone and bulge through one or more of a plurality of apertures located in the outer zone. In one embodiment, an additional crumple zone is present. The structure enables the helmet to divert linear and rotational forces away from the user's braincase.

Description

technical field [0001] The present invention relates to protective headgear, more particularly to sports or work site protective headgear, and especially to protective headgear designed to prevent or reduce head injuries caused by linear or rotational forces. Background technique [0002] The human brain is an extremely delicate structure that is protected by a series of enclosures that shield it from harm. The innermost layer, the pia mater, covers the surface of the brain. After the pia mater is the arachnoid, or spider-like membrane, which acts as a waterproof membrane. Finally, there is the dura mater, the tough, leather-like layer that covers the arachnoid and attaches to the bones of the skull. [0003] Although this structure is protected from penetrating trauma due to the bones of the skull, the softer inner layer absorbs too little energy before the force is transmitted to the brain. Additionally, while the skull attenuates some of the linear forces applied to th...
