Helmet liner suspension structure

A universal helmet-liner suspension structure selectively installable inside 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 include a locating host attachment site, and additional, other host attachment sites, such 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 position-locating guest affixing site which is commonly and substantially identically employable with the locating host attachment sites in all such helmet 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.
