Abstract
A protective helmet incorporates an inflatable liner that has front, crown, rear, left and right side portions. To ensure uniform inflation, the inflatable liner is comprised of a plurality of inflatable cells interconnected by a series of air passageways. The liner has a front portion that extends to the lower edge of the helmet and a rear portion that extends below the external occipital protuberance of the wearer's head, thereby providing a snug, comfortable fit and ensuring that the helmet will not rise up or lift away from the wearer's head.
