Patent

CA 2762276

The invention relates to a safety device that can easily be incorporated into any type of waterproofs and work clothes and is designed to protect people who fall into the sea accidentally, providing insulation against low water temperatures, as well as providing a heat source that considerably prolongs survival time in low-temperature water. The invention comprises: a main ring-shaped bag (1), the outermost part of which is provided with a plurality of long, narrow secondary bags (5); and a check valve (3) arranged on the surface of the main bag which contains sodium that, upon contact with water, produces a chemical reaction that seals possible points at which water could enter the clothing and provides a source of heat for the body.

L'invention concerne un dispositif de sécurité aisément incorporable à n'importe quel type de vêtements pour séjourner dans l'eau et de travail et conçu pour protéger des personnes tombées à la mer de façon accidentelle, conférant à ces dernières une isolation contre les basses températures de l'eau, ainsi qu'un apport de chaleur, qui prolonge de manière considérable le temps de survie dans des eaux à basse température. Il se compose d'un sac principal (1) de forme annulaire disposant dans sa partie la plus à l'extérieure de plusieurs sacs secondaires (5) de forme allongée et étroite, et une valve de retenue (3) disposée sur la surface du sac principal, lequel contient du sodium qui lorsqu'il entre en contact avec l'eau provoque une réaction chimique qui ferme les entrées possibles d'eau dans les vêtements et confère par ailleurs de la chaleur au corps.
