Abstract: A shoe insole structure which includes a non-springy, acceleration-rate-sensitive viscoelastic cushioning layer carrying, on its upper surface, a low-friction, abrasion-resistant, load-distributing, moisture-wicking overlayer.

Abstract: A method for making a multi-layer helmet shell wherein inner and outer, structural, load-bearing semi-rigid layers are spray-deposited onto opposite surfaces of a pre-shaped, pliable viscoelastic, acceleration-rate-sensitive, microcellular foam core.

Abstract: A multilayer helmet shell, and a method of making the same, are disclosed wherein inner and outer, structural, load-bearing semi-rigid layers jacket a viscoelastic, acceleration-rate-sensitive, microcellular foam core layer.

Abstract: A unitary helmet liner suspension structure which is designed for easy and quick and correct fitment into differently sized helmet shells whose specific sizes reside within a known and defined range of such sizes.

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.
