BIOMECHANICS AWARE HEADGEAR

摘要

Protective gear includes an outer shell layer connected to a middle shell layer through an outer energy and impact transformer layer. The middle shell layer is connected to an inner shell layer through an inner energy and impact transformer layer. The outer and inner energy and impact transformer layers flexibly connect the shell layers to absorb impact forces, rotational forces, shear forces, etc., and allow the various shell layers to move and slide relative to the other shell layers. The outer and inner energy and impact transformer layers may be constructed using gels, fluids, electro-rheological elements, magneto-rheological elements, etc. The protective gear may be formed as helmets or body protection for various activities and protect users from not only impact and penetrative forces, but rotational and shear forces as well.

主权项

1. A helmet comprising:
an outer protective layer; an inner protective layer; a first energy transformer layer including a plurality of elastomeric structures residing between the outer protective layer and the inner protective layer, the first energy transformer layer associated with a shear mechanism, wherein the shear mechanism allows the outer protective layer to slide relative to the inner protective layer; a liner layer connected to the inner protective layer, the liner layer configured to reside between the inner protective layer and a human head; a chin strap having a plurality of attachment points on the helmet, the plurality of attachment points including at least two attachment points on the inner protective layer, wherein the chin strap attachment points on the inner protective layer are configured to secure the inner protective layer to the human head while the outer protective layer is allowed to slide relative to the inner protective layer.
