Life jacket

Abstract

The invention relates to a life jacket which comprises an overcoat (1) and an inner core (2) with the floater effect. The inner core (2) is arranged in the interlayer of the overcoat (1); the inner core (2) is made of foam material formed by mixing and pressing NBR / PVC with soft hand feel and the density being of 0.034g / cm<3>; and the thickness of the part, which is arranged in the overcoat at the chest, of the inner core (2) is at least two times as that of the part, which is arranged in the overcoat at the back, of the inner core (2). The life jacket has the advantages that because the thickness of the part, which is arranged in the overcoat at the chest, of the inner core is at least two times as that of the part, which is arranged in the overcoat at the back, of the inner core, and the buoyancy of the inner core at the chest is large, when falling into the water, a user can automatically turnover the body to keep face upward, the life safety of the user who can not swim can be effectively ensured, the use is safe, and the effect is better; furthermore, the material of the inner core feels soft, the inner core not only has good fitting when being worn, but also is convenient for the user to stoop down, squat down or do various motions, moreover, because the density of the inner core is only 0.034 g / cm<3>, and the weight of each produced life jacket is less than or equal to 0.8 kg, so that the life jacket is light and convenient to carry.

Description

technical field [0001] The invention relates to a lifejacket, which is used for fishing in sea, river and lake, for entertainment such as riding a yacht, or for marine engineering operations, and for floating the user's body when a water disaster occurs. Background technique [0002] Existing a kind of patent No. CN93214217.6 name is called " super buoyancy lifejacket " Chinese utility model patent discloses a kind of structure, and its structure adopts a kind of novel waterproof, flame-retardant fabric to constitute the inner and outer layers of "lifejacket", The interlayer between the inner and outer layers has a specially treated non-absorbent, flame-retardant high-density polyethylene foam material interlayer, which is sewn into a specific form of chest and back. There are flashing belts and sub-shaped buckle clips. Nylon high-strength webbing is stitched together as a whole. The utility model has the advantages of being safe and reliable, super buoyant and warm, simpl...

AI Technical Summary

Problems solved by technology

But its shortcoming is that the buoyancy of this two-piece design of the chest and back is similar. When a person falls into the water, he will not automatically turn his body and keep his face upward, which will cause breathing difficulties to rescuers who are not suitable for water; Combustible high-density polyethylene foam material, if its foam sinks in the water for too long, its buoyancy will decrease, which will further consume the rescuer's physical strength, so its structure and material properties need to be improved
