FIELD: individual rescue equipment used in extreme situations. ^ SUBSTANCE: individual rescue apparatus has gas balloon and is made from water- and air-impermeable material which defines in operating state streamlined shape with double walls, with space between walls being adapted to be filled with gas having specific weight smaller than that of air. Space between walls is divided by meridional partitions into sectors communicating with one another through annular channel which is connected through pipe with gas balloon located within individual apparatus. Annular channel is formed within upper bottom, circumferentially thereof, in V-shaped slot along axis of symmetry. Each sector is connected to annular channel through radial apertures. There is zipper fastener on side surface of individual apparatus, said zipper fastener being equipped with lock at its inner side. In closed position, lock carrier is blocked by means of hook rigidly attached to wall. On lower bottom made in the form of rectangle with rounded sides there is rigidly fixed balloon with compressed air used as air for breathing. Breathing valve with flexible binder for opening thereof is located on the top within upper bottom. Diameter of upper bottom is within the width of lower bottom. Petal made from dense fabric is rigidly attached to lower side of zipper in axially symmetric manner, said petal being adapted for tightening of material and avoiding jamming of zipper fastener during closing thereof. ^ EFFECT: wider operational capabilities and enhanced reliability in operation of apparatus. ^ 2 cl, 4 dwg |
