摘要
A new inflatable liner for an aircraft or other protective helmet is disclosed. The liner includes a multiplicity of separate inflatable cells adjacently arranged in the general shape of a cap or of the inside of a helmet. Each inflatable cell includes a separate inflation tube. The inflation tubes extend out the back or side of the liner to one or more collector tubes. A valve controls a supply of inflatable fluid, typically pressurized air, to the collector tube. The inflation tubes may be grouped so that adjacent inflatable cells are differentially pressurized to provide impact energy absorption and so that inflatable cells on the sides of the helmet liner are more highly pressurized than cells on the top of the helmet liner to hold the helmet liner, and an accompanying helmet, more securely on a person's head.
