Aviation inflatable life jacket

Abstract

The invention discloses an aviation inflatable life jacket. The aviation inflatable life jacket comprises a water activated battery, a positioning lamp, a first pull rope, a first gas blow pipe, a first CO2 steel cylinder, a first airbag, a second airbag, a second CO2 steel cylinder, a second gas blow pipe, a second pull rope, a whistle, a waistcoat and a waterproof zipper. According to the aviation inflatable life jacket, the waistcoat made of a composite material replaces belts and belt buckles of a traditional life jacket, the waistcoat is soft in appearance and is integrally similar a traditional waistcoat, the waistcoat is more suitable for dressing concept of a person than the belts and the belt buckles, and the person unfamiliar with the life jacket can even rapidly wear the aviation inflatable life jacket correctly. The composite material contains polyurethane so that the waistcoat possesses very high elasticity, and therefore, a problem that an existing life jacket is difficult to wear is solved. When a user falls into water, the waistcoat can tightly coat the body of a drowning person by means of the elasticity of the composite material with high heat resistance so as tostop the heat from being transmitted from the human body to the water to be very great degree and protect the body temperature of the drowning person; and therefore, a problem that the existing life jacket cannot protect the body temperature of the drowning person is solved.

Description

technical field [0001] The invention relates to the field of aviation, in particular to an inflatable lifejacket for aviation. Background technique [0002] Aircraft lifejackets are one of the necessary equipment for operating aircraft across water, but the most commonly used inflatable lifejackets have problems such as difficulty in wearing and inability to protect body temperature when actual aircraft accidents occur. Airbus A320-214 made an emergency landing in the Hudson River accident in 2009. There were 33 passengers on board who escaped out of the plane and got life jackets, but until the end, only 4 people put on the life jackets correctly and tied their belts so that they could not will fall off. If a passenger puts on an airplane lifejacket but does not fasten the drawstrings and buckles correctly, the lifejacket will float up quickly after the passenger falls into the water, and the passenger's neck will be caught, causing suffocation and death. Some of the 41 p...

AI Technical Summary

Problems solved by technology

In the Hudson River accident, only 12.1% of the aircraft life jackets were worn correctly. Only the buckle works

For those who are not familiar with airplane life jackets, the first step is very simple, but the latter step is difficult for many people to do in panic airplane accidents (especially: life jacket wires, CO 2 The two drawstrings of the steel cylinder are mixed with other straps, which is easy to confuse, and it takes a long time to complete the wearing without understanding the lifejacket), the consequences of only doing the previous step and not the latter step are fatal

This shows that there is a problem of difficulty in wearing inflatable lifejackets for aviation at present.

[0003] At the same time, wearing a traditional aircraft life jacket after falling into the water, only the part above the head floats on the water surface, and the upper and lower parts of the body are in contact with the water. Since the water temperature may be very low, and the heat transfer capacity of water is much higher than that of air, this leads to The body is likely to lose heat too quickly, and eventually the body temperature is too low to cause a cold shock reaction, which may even cause the person who fell into the water to die within 3-5 minutes

This shows that the inflatable life jackets currently used in aviation do not have the effect of protecting the body temperature of those who fall into the water.
