controller admission port

35,35 ends is in sealing state when high, when air pressure is reduced to certain value, discharge the surplus air in it.The rear end of pressure loosening valve 38 is provided with hollow adjustment nut 41, is used for adjusting the thrust of spring 50.Be installed with limit pull rods 42 in the middle of the hollow adjustment nut 41, the lower end of limit pull rod 42 connects half ball valve 39, and its effect is the position that moves down of restriction half ball valve 39 and once more the seat is inflated, when needing inflation, handle earlier limit pull rod 42, move after making half ball valve 39, pressure loosening valve 38 sealings.The therebetween of sealed film 37 has instant electric detonator 46, and two leads of instant electric detonator 46 are connected on the safety switch 43, when safety switch 43 is positioned at the connection shelves, instant electric detonator 46 is detonated.Shown in Fig. 1,2,4, admission line 19 and appendix 20 are flexible pipes made from rubber, admission line 19 has two, article one, a end connects people's bodily form airbag the latter half 8, the other end connects controller admission port 35 ', and another a end connects adjusts piece 3, and the other end connects an admission port 35 of controller, and check valve 48 is set in this pipeline, be that the air pressure that control is adjusted in the piece 3 is not subjected to anticyclonic influence the in people's bodily form airbag the latter half 8.Loading line 20 1 ends connect controller air extractor duct 36, connect air bag 12 gentle arms 13 respectively behind the other end fork.Air bag preformed hole 10 is arranged on the cushion 4 human body crotch portion front slightly, runs through whole cushion 4 up and down; Gas arm preformed hole 11 is arranged on the waist both sides of human body on the backrest 2, and backrest 2 is run through in front and back; Air bag 12 gentle arms 13 all use nylon cloth airtight or the permeability to air difference to make.On the air bag 12 gentle arms 13 air bleed hole 16 is arranged all, and by 17 sealings of the bleeding plug made with rubber, air bag 12 gentle arms 13 are folded state and are placed in the preformed hole 10,11 at ordinary times.Gas arm 13 is made Contraband shape, and air bag 12 is made the horizontal ellipse that length is about 40CM, 50CM, 30CM.Elastic 21 usefulness elasticity are big, and the elastomeric material that pulling force is strong is made, and intermediate sleeve is on elastic sleeve 23, and two ends are fixed on the elastic adjustment and buckle on 22, and keep stronger pulling force, elastic adjustment to buckle 22 both sides that are fixed on top, backrest 2 back.The existing automobile tyre inflation valve of charge valve 44 usefulness, this charge valve is separately positioned on to be adjusted on piece 3, people's bodily form airbag the first half 6 the latter halfs 8, head rest 1 backrest, 2 lower floors and peripheral part 7, cushion 4 lower floors and the peripheral part 9, to satisfy the requirement of the different air pressure of seat different parts.

When traffic accident takes place, can be by the power connection of manual control of chaufeur or crash sensor control safety switch 43, sealed film 37 is blown by the instant electric detonator in it 46, people's bodily form airbag the latter half 8, the first half 6 and the pressurized air of adjusting in the piece 3 press off check valve, inflate to air bag 12 gentle arms 13 by loading line 20, air bag 12 ejects and expands, and the leg crotch position of human body is pressed on the cushion 4.The both shoulders of clasping human body that two gas arms 13 eject from bottom to top, backrest 2 is under the tension of elastic 21 and human body hypsokinesis together, along with increasing of air bag 12 gentle arm 13 internal gas pressures, when the air pressure in people's bodily form airbag the first half 6 the latter halfs 8 and the adjustment piece 3 are reduced to certain value, half ball valve 39 in the pressure loosening valve 38 moves forward under the thrust of spring, remaining pressurized air is discharged from deflation hole 40, human body is absorbed in the human body connected in star that forms in the middle of the seat, the gentle arms 13 of air bag 12 are because the effect of check valve 49 still keeps original air pressure, jointly human body are formed fixing with the peripheral part at seat.When certain angle was arrived in backrest 2 hypsokinesis, locking tooth 32 and locking button 33 coincide, and with the backrest locking, entered the safety guard-safeguard state this moment fully.When bumping, fix because the peripheral part at seat and air bag 12 gentle arms 13 have formed failure-free to human body jointly, and absorb the inertia impulsive force of human body, avoided the collision of human body and vehicle.When vehicle is impacted distortion, because human body is in the state of couching at this moment, and is absorbed in the middle of the seat, thereby enlarged survival space, reduced the danger that human body is pushed by vehicle deformation.When overturning, fix because air bag, gas arm and seat peripheral part have carried out failure-free to human body, thereby reduced the chance that personnel roll and collide in car.After the accident, as long as the bleeding plug on the gentle arm of air bag under dialling can be removed fixing human body.

Embodiment two: people's bodily form gas the first half 6 is connected with cushion 4 shown in Fig. 7,8,9, and both sides, backrest 2 front are provided with gas arm preformed hole 11, and people's crotch portion slightly is provided with air bag preformed hole 10 in the front on the cushion 4.The shape of air bag 12 gentle arms 3 and manufacturing materials are all as described in the embodiment one.The gentle arm of air bag is in rugosity at ordinary times and places respectively in the air bag preformed hole 10 gentle arm preformed holes 11.The admission port 35 of control setup is connected with cushion 4 by admission line 19, and air extractor duct 36 connects air bag 12 gentle arms 3 respectively after diverging by loading line 20.Safety switch 43 energized when accident takes place, instant electric detonator 46 detonates, get through the path between controller admission port 35 and the air extractor duct 36, pressurized air in people's bodily form airbag the first half 6 and the cushion 4 presses off check valve 49, to air bag 12 gentle arm 13 inflations, air bag 12 ejects pushes down personnel's thigh and waist crotch position, two gas arms 13 are clasped personnel's both shoulders from bottom to top, when the air pressure in cushion 4 and bodily form airbag the first half 6 is reduced to certain value, pressure loosening valve 50 is opened, discharge the surplus air in it, further reduce seat height, air bag 12 gentle arms 3 still keep original air pressure by the effect of check valve 49, air bag, gas arm and the common fixing human of base layer perimeter part, owing to the transfer of rubber seat internal gas pressure, periphery branch shrinks to the centre simultaneously, also human body is played fixation, enter safe condition this moment fully.Because human body has been produced firm fixing, the collision of avoiding human body and vehicle to produce reduces with seat height owing to people's physical efficiency when vehicle deformation, thereby has enlarged survival space, has reduced the injury that human body is pushed by vehicle deformation.This inflatable automobile safety seat not only can be used as the seat and the safety device of some vehicles, also can be used as the back row seats of some vehicle, because the transfer fully of cushion 4 compressed airs has been abdicated more space for the hypsokinesis of dress circle backrest 2.

Pin locking apparatus of the present utility model, locking tooth and locking button adopt metal material processing, and all the other all can adopt elastomeric material to process.
