Zusammenfassung:FIELD: face-masks. ^ SUBSTANCE: holding device for protection face-mask, which is fixed at protection helmet, has fitting hooks connected with flexible length-adjusted belts. Hooks are made for introduction into receiving recesses made onto protection helmet. Rest, working with friction and geometrical closing, in combination with flexibility of constriction belt, which serves simultaneously for individual adjustment of mask when it is put onto face, prevent automatic opening of hook. Slide members matched with rests for shift provide automatic optimal balancing of constriction belts. Connection between constriction belt and adjusting hook is made by means of cast holder formed on constriction belt, which is held for geometrical closing in recess, connected with adjusting hook of clamp member. ^ EFFECT: simplified design; comfort at usage. ^ 7 cl, 3 dwg
