Abstract
A temperature moderation apparatus is structured to be positioned in vehicle passenger compartment. The apparatus includes an outer shell defining an interior of the shell, the wall has an exterior surface structured and positioned for physical contact with a skin surface of a vehicle occupant. The outer shell wall also has a plurality of through-holes formed therein. A phase change material element is positioned within the shell interior. The phase change material element includes a stretchable, thermally-conductive outer wall and a quantity of phase change material positioned therein. A pressurization mechanism is coupled to the phase change material element, the pressurization mechanism is structured to pressurize the phase change material element so as to force portions of the phase change material element to extend from the interior of the shell into associated ones of the through holes and past the outer shell wall exterior surface.
