Abstract
A suspension system for protective headgear comprising a head band adapted to extend around a wearer's head, and a plurality of tension members secured at their outer ends to the headgear adjacent the skirt thereof and at their inner ends to the head band for holding the head band spaced from the inner surface of the headgear. Each tension member is formed of relatively inextensible material with a transversely extending pocket and has a tube of elastomeric material in the pocket enabling extension of the member within a limited range of extension upon tensioning thereof, whereby with the headgear worn by a wearer and upon application of an impact load to the front, back, or sides of the headgear, the headgear moves in the direction of the force with resultant tensioning and elongation of certain of the tension members, the range of elongation of the members being such as to prevent engagement of the headgear with the wearer's head and the tubes in the pockets of the elongated members deforming to attenuate the shock upon the wearer from the applied load.
