Patent ID: 7246385

Claim:
Helmet chin-strap harness structure comprising a pair of bilaterally symmetric, bilaterally equi-flex, non-rigid, fabric-strap substantially mirror-image, flexible lateral elements which define opposite sides for the harness structure, and which include, one each, elongate translation slide regions, and a bilaterally symmetric chin-strap substructure having laterally opposite sides releasably attachable through included reverse bends, having inside attached frictioning patches, for fore-and-aft translational, relative-motion sliding on, and cinch-positional-locking relative to, said slide regions in said lateral elements, said bends and patches being structured for closing progressively upon said slide regions during cinching of the harness structure, thus progressively to inhibit relative-motion sliding between said slide regions and said bends and patches in said chin-strap substructure.
