When being charged to suitable state, air inlet button, air inlet pipeline open circuit are unclamped, air bag maintains inflated condition, and inflated condition such as Fig. 3 is empty
Shown in line；When needing to reduce or emptying the gas in air bag, need to press exhaust button, exhaust pipe and exhaust connection tracheae
Access, the gas in air bag are discharged from exhaust pipe through control switch unit from exhaust connection tracheae, empty or be vented to air bag
To exhaust button when being suitble to state, is unclamped, the air bag after gas emptying, which is rolled up, to be fitted in by back, and it is empty in addition not occupy seat
Between, the air bag state after vent gas is as shown in figure 3 by the solid lines.
Detailed description of the invention:
Fig. 1 is the D structure schematic diagram of the utility model；
Fig. 2 is the local structure schematic diagram of Fig. 1；
Fig. 3 is the organigram of air bag expansion and contraction state；
Fig. 4 is the diagrammatic cross-section of intake valve air-suction state；
Fig. 5 is the diagrammatic cross-section of intake valve not air-suction state.
Specific embodiment:
The utility model public transportation vehicle inflatable waist-protection seat includes 1 He of seat on public transportation vehicle
It is located at the air bag 2 of backrest Yu cushion turning point, the seat side is equipped with control switch unit 3, the control switch list
First 3 first sides connect tracheae 9 with air inlet by exhaust connection tracheae 8 and connect with air bag 2, and the second of the control switch unit 3
Side is connect by air inlet pipe 7 with the feeder 10 of public transportation vehicle, is set between the air inlet pipe 7 and air inlet connection tracheae 9
There is the intake valve 11 being located on control switch unit, the intake valve 11, which is equipped with, connect tracheae with air inlet for opening and closing air inlet pipe
The air inlet button 4 of connection, exhaust pipe 6 is also connected in described control switch unit second side, and the exhaust pipe 6 is connected with exhaust
The exhaust valve 12 being located on control switch unit is equipped between tracheae 8, the exhaust valve is equipped with for opening and closing exhaust pipe and row
Gas connects the exhaust button 5 of tracheae connection.
Further, rationally for easy to make, design, above-mentioned air bag is made of airtight flexible material, and is vented
