Abstract
A site-selectable, helmet-installable load-cushioning pad structure employable inside a helmet shell as a part of a plural-spaced-pad distribution featuring a compressible viscoelastic foam core which resists rapid, but not slow-movement, compression. Associated methodology includes the steps of providing such a structure for installation inside the shell of a helmet, and pre-arming the core of that structure with a load-response characteristics which (a) resists sudden-movement, rapid compression, yet (b) offers less resistance to slow-movement compression. An encapsulating moisture barrier layer may be provided around the foam core.
