The lifesaving air bag comprises an air bag body, an oxygen bag and an oxygen cover, wherein the air bag body is communicated with an air storing tank through an air pipe, consists of a protecting layer and a plastic rubber film and comprises leg air bags, a back air bag, a head air bag and wing air bags; the bottom of the back air bag is communicated with the top ends of the leg air bags; the top of the back air bag is communicated with the bottom of the head air bag; the wing air bags are respectively arranged on the two sides of the back air bag; the oxygen bag is stuck to the head air bag; the oxygen cover is fixed to the oxygen bag. The lifesaving air bag is simple in structure and low in cost. Under the emergent condition that a fire disaster is caused on a plane or the plane is out of control, a passenger only needs to open a liquid nitrogen air storing tank switch and an oxygen storing tank switch, then liquid nitrogen fully fills the whole air bag immediately, the human body is wrapped in the air bag, and external impact and burning are prevented; meanwhile, the passenger can directly suck oxygen through the oxygen cover; therefore, even the passenger cannot escape from the plane, the passenger can be protected.

Description

Life saving air bag

Technical field

The utility model relates to lifesaving appliance, particularly relates to a kind of life saving air bag.

Background technology

At present, airplane is the fastest travel modal, once but aeroplane accident, survivor is very few.Especially 6 minutes after taking off and in land 7 minutes, the accident that the most easily meets accident, apart from aeromedicine man statistics, has 65% accident to occur in these 13 minutes in China, and therefore airplane should on request, must be fastened seat belts before taking off.Aerial common emergency situation has sealing type pressure cabin low suddenly; catch fire or mechanical breakdown etc.; in the time of emergency landing; safety strap is no doubt being brought into play very large effect; protection personal safety, but once big fire occurs in cabin, cannot put out time; passenger is again without any the fire equipment for the protection of oneself, and life security is subject to serious threat.Therefore, the utility model people is through concentrating on studies and test of many times, utility model a kind of life saving air bag, running into above-mentioned clutch, can protect Whole Body, make the person out of danger.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.

As shown in Figure 1 to Figure 3, the structural representation of the utility model life saving air bag, it comprises airbag body 1, oxygen bag 2 and oxygen mask 3; Airbag body 1 is communicated with storage tank 4 by tracheae; airbag body 1 is made up of protective cover 16 and plastic cement rete 15; plastic cement rete 15 is attached to protective cover 16 outsides, and protective cover 16 is made for nylon 66 material, and nylon 66 fatigue resistances and rigidity are higher; resistance to effect of heat is better; friction coefficient is low, and resistance to abrasion is good, and plastic cement rete 15 is made for TPU material; Chinese is TPUE, has that intensity is high, a good toughness, the characteristic such as wear-resisting, cold-resistant.

On airbag body 1, be sewed with some interlaced separation lines, make to be latticed after airbag body 1 inflation, strengthen gas uniform and the shock resistance of airbag body 1, airbag body 1 comprises shank air bag 11, back air bag 12, head airbag 13 and alar part air bag 14, and shank air bag 11, back air bag 12, head airbag 13 and alar part air bag 14 form the air bag that a whole continuous phase is logical.Concrete, the bottom of back air bag 12 is communicated with the top of shank air bag 11, its top is communicated with the bottom of head airbag 13, the calf bladder 111 that shank air bag 11 comprises thigh air bag 112 and is arranged on both sides and is communicated with it, calf bladder 111 is chicken-core-shape, after inflation, be low around shape after front height, thigh air bag 112 is communicated with back air bag 12.Alar part air bag 14 is separately positioned on the both sides of back air bag 12, and is communicated with back air bag 12, and alar part air bag 14 is made as chicken-core-shape, and is around shape, makes in head airbag 13 is wrapped in.Head airbag 13 is bending, and its bending angle is preferably 60 degree-90 degree, and oxygen bag 2 is bonded on head airbag 13, and is connected with oxygen container 5 by tracheae, and oxygen mask 3 is packed on oxygen bag 2, and is communicated with oxygen bag 2.In addition, on head airbag 11 and oxygen bag 2, exhaust safety valve is all installed, to ensure the stability of air pressure in air bag, in storage tank 4, device has liquid nitrogen gas.

The nylon material that it is good, fire-retardant that protective cover of the present utility model can adopt air-tightness is made, and also can adopt other fire-retardant soft material (as polyester material) of holding one's breath to make, simultaneously, the plastic cement rete of its internal layer is preferably TPU material and makes, possesses very strong air-tightness, in the time being full of liquid nitrogen gas in air bag, because liquid nitrogen gas is fire-retardant cryogenic gas, there is the feature of fire-retardant and low temperature, outside nylon 66 protective coveres and plastic cement rete can be remained to lower temperature, therefore, even if in the situation that outside burning things which may cause a fire disaster constantly burns, in short time, be difficult to make nylon 66 protective coveres and plastic cement rete to reach fusing point, personnel and outside are isolated completely, simultaneously, air bag after inflation has stronger shock resistance, through verification experimental verification, this life saving air bag is filled with in liquid nitrogen gas punching press 0.5 barometric pressure situation, can the about 500kg of impact resistance power, can in the time of the flame of 1000 ℃ of high temperature left and right, in air bag, still keep low temperature, can effectively prevent that passenger from being burnt and external impact.

When use, air bag entirety is laid on seat, calf bladder hangs naturally below seat board; passenger rides on thigh air bag; once presence of fire, first passenger starts the switch of liquid nitrogen storage tank, and liquid nitrogen gas is full of whole air bag from calf bladder rapidly; wherein calf bladder is encircled shank interior rapidly; and calf bladder front end is higher than knee, like this; after calf bladder inflation, not only surround shank and avoid burning things which may cause a fire disaster infringement, also can protect knee to avoid extraneous and clash into.Thigh air bag, back air bag, head airbag are isolated from the outside passenger; head airbag is bending, can carry out omnibearing protection to people's the crown and face, after alar part airbag aeration, becomes around shape; in the upper part of the body more than human body thigh is wrapped in completely, blocking-up burning things which may cause a fire disaster.Meanwhile, passenger can open the switch of oxygen canister, oxygen is full of in oxygen bag, then utilize oxygen mask to breathe, prevent from the situations such as anoxic, air be poisoning exhaust safety valve being all installed on head airbag and oxygen bag, gaseous tension in air bag is remained in safe range, gas in air bag is realized gas circulation in the process of constantly inflation and exhaust, remains that air bag has lower temperature, ensures that air bag is not burnt.When passenger can following machine, if the outside condition of a fire not yet stops, passenger can disconnect carbon dioxide tracheae and oxygen hose, carries air bag and depart from aircraft under the protection of air bag.If the outside condition of a fire stops, passenger only need close the switch of oxygen canister, liquid nitrogen storage tank, then pushes alar part air bag aside with hand, can flee from.

Life saving air bag of the present utility model, not only for the act of rescue on aircraft,, also can install on train, automobile meanwhile, at clutch, personal safety is protected.

Finally it should be noted that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
