equipment for protecting user's head. SUBSTANCE: safety helmet accessories include interconnected retaining members made in the form of three-dimensional flexible segments with hermetically sealed hollow walls filled with granular filler. When helmet is fixed on user's head, wall cavities are vacuumized. Retaining member are secured to inner side of flexible and nonstretchable enclosure which tightly embraces user's head and may be attached to helmet body. Retaining members are of two-compartment type. Compartment free of filler contains working fluid having excessive pressure, which is established, when pressure in compartment charged with filler is decreased. Such construction prevents formation of gaps and decrease in strength of mechanical coupling between helmet accessories and user's head. EFFECT: simplified construction and convenient usage. 4 dwg
