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.

1. A stretchable-adjustable, cushioning helmet insert employable in the hollow, domed interior of a selected-size helmet shell, said insert comprisinga generally domed cap adapted for installation within such a shell interior, and formed of a reversibly stretchable fabric, by way of which the cap is biased toward a nominally size-contracted state in which it possesses a size that allows it to be freely placed and received within the hollow, domed interior of such a shell in a manner wherein these exists a defined, surrounding expansion space between the outside of the cap and the inside of the shell allowing for a defined amount of reversible outward expansion of the cap within the shell, andcushioning structure in the form of plural, spaced cushioning pads positionally affixed to said cap on the inside thereof 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.2. The helmet insert of claim 1, wherein the adaptation of said cap for installation in a shell is one which is characterized as a defined-orientation adaptation.3. The helmet insert of claim 1, wherein said pads are positioned relative to said cap in a manner whereby they are respectively disposed inside a helmet shell to engage defined regions on the head of a user.
