FIELD: individual life-saving appliances. SUBSTANCE: reservoir charged with compressed gas is made in form of buckle of belt having form of inflatable member 1. Interior of buckle 2 is filled with compressed gas. It is made in form of single-member solid plastic structure. Part of wall of buckle 2 adjacent to inner cavity of inflatable member 1 tightly connected to buckle by one of its ends has thinned area which may be broken by depressing through wall of inflatable member 1. This section of wall may be provided with tubular section 3 with local circular thinned area 4 which enters inflatable member 1. When this area of wall is broken, gas expands over thinned area 4, thus filling the inflatable member. Elongation of belt which occurs in filling it with gas makes it possible to shift the belt to victim axilla. EFFECT: enhanced reliability and constant readiness for immediate use. 4 cl, 4 dwg |
