Helmet liner suspension structure

A universal helmet-liner suspension structure selectively installable in a fixed and positionally stabilized condition inside, and directly to, the shells of helmets which are characterized by different sizes in a defined range of sizes, and wherein such shells have a generally common pattern of plural, pre-established and located, spaced host attachment sites with respect to which different pairs of adjacent such sites have differing specific spacings that differ in a known way in relation to helmet-shell size, and wherein said host attachment sites includes a rear, central locating host attachment site, and additional, other host attachment sites, said structure comprising

• an elongate, resilient band having a long axis and opposite ends, said band being bendable, and selectively closable upon itself, to form a generally-closed, endless, curved loop fittable, in a universal manner, closely within the insides of the shells in such helmets, and throughout the mentioned range of helmet sizes, and
• spaced, anchor-accommodating, guest affixing sites furnished in said band, including (a) a longitudinally central, position-locating guest affixing site which is commonly and substantially identically employable with the rear, central locating host attachment sites in all such helmet shells to anchor said band in place and in a positionally stabilized manner in such shells, and (b) plural, range-accommodating, other guest affixing sites which freely accommodate attachable fitment of the band, on a one-to-one basis, at the respective locations of said other host attachment sites in such shells.
