Abstract
A stretchable-adjustable, cushioning helmet insert employable in the hollow, domed interior of a helmet shell. The insert includes a generally domed cap formed of a reversibly stretchable fabric, and adapted for installation within the interior such a shell, and cushioning structure in the form of plural, spaced cushioning pads positionally affixed to the inside of the cap in a manner whereby expansion and contraction of the cap causes spatial retreat and closure, respectively, of the spacings existing between each pad and its neighboring pads. This insert accommodates proper-fit the “insertion”, into a single-size helmet shell, of the different “effective” head sizes associated with a single user, such as a firefighter, who may, at certain times, be wearing no other headgear, and at other times, may be wearing auxiliary (and somewhat bulky) head-borne equipment, such as an oxygen mask.
