Abstract
A cushioning and head-protecting liner insert for the inside of the shell in a helmet includes fore and aft cushioning elements each formed of an expanse of a non-springy, acceleration-rate-sensitive, viscoelastic material, with each element possessing, throughout, a uniform thickness which is the same as that possessed by the other element, and with the two elements having edges which are disposed edge-to-edge, but slightly spaced, adjacent one another along a single, continuous, arcuate, reverse-bend line which sweeps from one lateral side of the rear of the insert, at a location spaced laterally from the insert's fore-and-aft extending, laterally central plane, through and over the crown of the insert, to a mirror-image, spaced location on the opposite lateral side of the rear of the insert.
