LAYERED PROTECTIVE STRUCTURES

摘要

Protective structures that may be used in various protective gear items, such as helmets and the like. In some embodiments, the protective structure may comprise a layered structure having three distinct layers. The various layers may be selected, arranged, and configured to provide for improved protection at multiple velocities, such as high velocity impacts and low velocity impacts. Some embodiments may also, or alternatively, be configured to provide improved protection and/or durability for multiple impacts at the same portion of the helmet over time.

1. A helmet, comprising:
a layered protective structure shaped to fit over a head of an individual, the layered protective structure comprising:
a first layer;a second layer positioned internally of the first layer, wherein the second layer comprises a more rigid and less compressible material than the first layer, and wherein a thickness of the second layer is less than a thickness of the first layer; anda third layer positioned internally of the second layer, wherein the third layer comprises a compressible, resilient material configured to compress and rebound upon being deformed, and wherein a thickness of the third layer is greater than a thickness of the second layer.
