Benefits of technology

The patent describes a protective gear that can be used for various activities. It has a special outer layer that can protect against impact and rotational forces. A padding assembly can be added on top of the outer layer, which can absorb normal forces. The padding layer can be attached to the outer layer through an interface layer that allows for sliding motion, reducing tangential forces. In some cases, the padding layer can be made up of multiple pieces that can be linked together with elastic material. The technical effects of the invention are improved protective gear that can provide more comprehensive coverage and comfort for users.

Problems solved by technology

Nonetheless, the effectiveness of protective gear remains limited.

example embodiments

[0027]Protective gear such as knee pads, shoulder pads, and helmets are typically designed to prevent direct impact injuries or trauma. For example, many pieces of protective gear reduce full impact forces that can structurally damage an area of contact such as the skull or knee. Major emphasis is placed on reducing the likelihood of cracking or breaking of bone. However, the larger issue is preventing the tissue and neurological damage caused by rotational forces, shear forces, oscillations, and tension / compression forces.

[0028]For head injuries, the major issue is neurological damage caused by oscillations of the brain in the cranial vault resulting in coup-contracoup injuries manifested as direct contusions to the central nervous system (CNS), shear injuries exacerbated by rotational, tension, compression, and / or shear forces resulting in demyelination and tearing of axonal fibers; and subdural or epidural hematomas. Because of the emphasis in reducing the likelihood of cracking ...

Abstract

Protective gear includes an outer shell layer connected to a middle shell layer through an outer energy and impact transformer layer. A padding assembly can be provided over the outer shell layer. The padding assembly can include a padding layer configured to absorb forces normal to the outer shell. The padding assembly can be coupled to the outer shell via an interface layer that allows the padding layer to slide over the outer shell layer in response to tangentially applied forces. The interface layer and associated sliding motion can reduce the tangential forces transmitted through the padding layer to the outer shell while still allowing normal forces to be absorbed. 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.

Description

TECHNICAL FIELD[0001]The present disclosure relates to biomechanics aware protective gear.DESCRIPTION OF RELATED ART[0002]Protective gear such as sports and safety helmets are designed to reduce direct impact forces that can mechanically damage an area of contact. Protective gear will typically include padding and a protective shell to reduce the risk of physical head injury. Liners are provided beneath a hardened exterior shell to reduce violent deceleration of the head in a smooth uniform manner and in an extremely short distance, as liner thickness is typically limited based on helmet size considerations.[0003]Protective gear is reasonably effective in preventing injury. Nonetheless, the effectiveness of protective gear remains limited. Consequently, various mechanisms are provided to improve protective gear in a biomechanically aware manner.SUMMARY[0004]Protective gear, including an outer shell layer connected to a middle shell layer through an outer energy and impact transforme...
