Abstract
A plural-layer body-contacting cushioning interface structure which is interposable the human body and an external structure, such as a helmet. The cushioning structure of the invention, in one preferred form, has a body-facing side which contacts the body, and a load-facing side which contacts the mentioned external structure. Intermediate these sides is a moisture-wicking layer which is designed to contact, and draw moisture away from, the body, a continuous, moisture-blocking, gas-permeable barrier layer adjacent the moisture-wicking layer, and an acceleration-rate-sensitive cushioning structure disposed protectedly within the barrier layer which fully encapsulates the cushioning structure.
