Title: Safety helmet

Abstract: A safety helmet comprising an inflatable, interconnected air-cushion system wherein the air-cushion system is positioned in the lower part of an integral helmet. The integral helmet has a tapered portion extending in a downward direction below the chin of the wearer, and has a frontal opening for the face. The air cushion system is positioned within a pocket in the helmet and extends from the lower edge of said helmet to at least the level of the ears, but not higher than the level of the temples of a wearer of the safety helmet. The air-cushion system comprises a continuous band of two flexible foils, and means for interconnecting said foils in an air-tight manner, preferably comprising cross-pieces extending between the foils in such a way that the foils and the cross-pieces form two inflatable cheek cushions and one inflatable neck-cushion. Connecting passage-ways between the cheek cushions and the neck cushion are provided, and throttling passageways are positioned between the non-inflatable areas and the inflatable areas.
