Carry on the back the upper end of 3 rear surfaces, the lower end of backrest 3 rear surface；Described feeder is for providing compressed-air actuated device, such as air pressure
Contracting machine.Described feeder 11 connects air intake control valve A, air intake control valve B, air intake control valve C respectively by air inlet pipeline 13,
For inflating to headrest air bag 5, backrest top air bag 6, backrest lower airbag 7；Described feeder 11 is connected with ECU14,
It is operated under the control of ECU14.
ECU14 is the core of whole device, may be integrally incorporated in the central controller of vehicle.ECU14 senses according to speed
The Vehicle Speed of device 15 Real-time Collection, it is judged that whether motor vehicles occurs emergency brake or head-on crash, and then determines motor-driven
Whether car gasbag-type safety seat apparatus works.When motor vehicles generation emergency brake or head-on crash, ECU14 is according to gas pressure
Inside air bag gas pressure (change) information that force transducer gathers, it is judged that heel row driver leg or head impact air bag violent
Degree, the aperture of the disappointing control valve of regulation in real time, thus by the disappointing farthest protection heel row occupant safety of air bag.When tightly
Bringing to a halt or after head-on crash terminates, ECU opens air intake control valve, closes control valve of losing heart, feeder 11 pass sequentially through into
Air pipe 13, air intake control valve are filled with compressed air to air bag, make headrest air bag 5, backrest top air bag 6, backrest lower airbag 7
Recover original swelling state, with the outline that headrest 1, backrest 3, medicated cushion 4 collectively form seat system again, in order to next time makes
With.Finally, after gas pressure sensor detection gassy, ECU terminates the work of motor vehicle air bag formula safety seat apparatus.
In order to reach when automotive emergency brake or head-on crash, effectively protect the purpose of heel row occupant safety, this
Bright realized by following steps:
(1) after motor vehicles starts running, the travel speed of vehicle speed sensor 15 Real-time Collection vehicle, and will collect
Vehicle Speed signal sends to ECU14, when ECU14 is according to the Vehicle Speed of vehicle speed sensor 15 Real-time Collection, sentences
When determining motor vehicles generation emergency brake or head-on crash, ECU14 determines that motor vehicle air bag formula safety seat apparatus is started working；
(2) when the heel row driver leg by belt restraints clashes into backrest lower airbag 7, ECU14 is according to gas pressure
Gas pressure (change) information within backrest lower airbag 7 of sensor C83 Real-time Collection, when pressure varies more than setting
During threshold value, control the aperture of disappointing control valve C93 in real time so that the gas leak in backrest lower airbag 7, thus pass through backrest
The disappointing absorbing impact energy of lower airbag 7, is farthest alleviated or avoided the injury of heel row driver leg；
(3) when the heel row occupant's head by belt restraints clashes into headrest air bag 5, ECU14 senses according to gas pressure
The headrest of device A81 Real-time Collection gas pressure (change) information within air bag 5, when pressure varies more than the threshold value of setting,
Control the aperture of disappointing control valve A91 in real time so that the gas leak in headrest air bag 5, thus losing heart by headrest air bag 5
Absorbing impact energy, is farthest alleviated or avoided the injury of heel row occupant's head；
(4) when the heel row occupant's head by belt restraints clashes into backrest top air bag 6, ECU14 is according to gas pressure
Gas pressure (change) information within backrest top air bag 6 of sensor B82 Real-time Collection, when pressure varies more than setting
During threshold value, control the aperture of disappointing control valve B92 in real time so that the gas leak in backrest top air bag 6, thus pass through backrest
The disappointing absorbing impact energy of top air bag 6, is farthest alleviated or avoided the injury of heel row occupant's head；
(5) after emergency brake or head-on crash terminate, ECU14 open air intake control valve A101, air intake control valve B102,
Air intake control valve C103, and close all of disappointing control valve, feeder 11 is respectively by air intake control valve A101, air inlet control
Valve B102 processed, air intake control valve C103, be filled with headrest air bag 5, backrest top air bag 6, backrest lower airbag 7 by compressed air
In, make three air bags recover original swelling state, with the foreign steamer that headrest 1, backrest 3, medicated cushion 4 collectively form seat system again
Wide, in order to next time uses；
(6) real according to gas pressure sensor A81, gas pressure sensor B82, gas pressure sensor C83 as ECU14
Time the headrest gas pressure information within air bag 5, backrest top air bag 6, backrest lower airbag 7 that gathers, it is determined that three air bags
When recovering original swelling state, ECU14 closes air intake control valve A101, air intake control valve B102, air intake control valve C103；
(7) last, ECU14 terminates the work of motor vehicle air bag formula safety seat apparatus.
Wherein, in step (2), (3), (4), the air leakage amount of the aperture of control valve of losing heart or air bag according to heel row occupant to gas
Depending on the impact force of capsule, its corresponding relation records according to test or the simulation result of different impact forces；When heel row occupant's head is first
Clash into headrest for front row seat rear portion, then when clashing into backrest rear upper, (3) and step (4) in steps；When heel row occupant's head
When clashing into headrest for front row seat rear portion, in steps (3), but without step (4)；When heel row occupant's head only clashes into front-row seats backrest
During rear upper, in steps (4), but without step (3).
The a series of detailed description of those listed above is only for the feasibility embodiment of the present invention specifically
