<p>A padding structure for use in helmets and other athletic equipment. The structure is characterized by a resilient padding arrangement which is adapted to be manufactured in different sizes whereby the equipment can be fit to the requirements of different wearers, and the padding structure is also characterized by the ability to absorb the force of impacts in a highly efficient manner irrespective of the particular fitting requirements. The structure consists of a housing of substantially air-impervious material containing a sandwich comprising a first layer of slow-recovery resilient material and a second layer of a softer resilient material. The softer material is adapted to be included in various thicknesses to accommodate different fitting requirements whereby the padding structure can be utilized for wearers having substantially different needs. The fitting material is of a density such that it will be normally slightly compressed without affecting the slow-recovery material so that the impact attenuating ability of the latter is not affected. The housing for the sandwich preferably defines at least one small opening whereby air is adapted to be discharged from the housing in response to an impact for thereby assisting, e.g. to the extent of about 10 percent, in absorbing the force of the impact.</p> |
