Close occupant's back.The air bag 8 for being used to support flexible portion 2, inflating air are additionally provided between flexible portion 2 and rear sealing plate 1
Capsule 8 is shrinkable and expands and then match the differently curved degree of flexible portion.
The flexible portion 2 includes vertically arranged, strip flexible support, and flexible support is by one and is located at flexibility
The right and left at partial middle part, the front side of flexible support is arranged at intervals with multiple horizontal stripes 22 along flexible support extending direction, soft
Property support and multiple horizontal stripes 22 collectively form the back-supported structure for being used to support occupant's back.Flexible support includes flexible rib
21, on the rear side of flexible rib 21 along its length on be arranged at intervals with multiple movable blocks 23, the front end rotation of movable block 23
It is assemblied on flexible rib 21, rubber block 24 is provided between the rear end of adjacent activities block 23.
Backrest frames are equipped with the horizontal concrete chute 31 extended along the longitudinal direction and the longitudinal chute extended in the vertical direction
35, longitudinal chute 35 is fixed on rear sealing plate 1, and guiding is equipped with sliding block 32, the flexible support of flexible portion in horizontal concrete chute 31
It is connect with sliding block 32, the driving mechanism is combined driving device, including for driving the end of flexible portion to move forward and backward
The longitudinal driving device 34 that the end of lateral driver device 33 and driving flexible portion moves up and down, longitudinal driving device 34 are stretched
Contracting end is connect to drive horizontal concrete chute 31 to move up and down with horizontal concrete chute 31, and then is moved up and down with movable slider 32, laterally driven
Device 33, which is oriented to, to be assemblied in longitudinal chute 35 and its telescopic end is connect to move up and down with horizontal concrete chute 31 with sliding block 32
Driving sliding block 32 is moved forward and backward in the process.
The vehicle further includes the control system for controlling driving mechanism 3 and the movement of air bag 8.The control system
System includes controller and the front side positioned at flexible portion, the front side for detecting pressure on top surface between occupant's back and flexible portion
Pressure sensor 4, controller and 4 communication connection of front side pressure sensor are simultaneously controlled by the feedback signal of front side pressure sensor
Driving mechanism movement.Control system further includes the rear side setting of flexible portion for detecting between flexible portion and air bag
The backside pressure sensor of pressure on top surface, the controller connect with backside pressure sensor communication and pass through backside pressure sensor

Personal control 9.In said structure, controller can integrate on the entire car controller of vehicle, or be separately provided
Singlechip controller on each seat.
Seat in the present invention in actual use, in the case where user leans against seat, when the back of user
When portion region or lumbar region are in vacant state, front side pressure sensor 4, which can collect, leans against surface portion areal pressure not
Foot, front side pressure sensor 4 issue signal and the sliding block 32 positioned at 2 lower end of flexible portion are promoted to drive in lateral driver device and longitudinal direction
It is forwardly and upwardly moved under the driving of dynamic device, increases by 2 lower knuckle rate of flexible portion, and then make flexible portion close to human body
Back, the pressure between backside pressure sensor sensing to flexible portion and air bag 8 reduces at the same time, and backside pressure passes
Sensor issue signal promote air bag 8 inflation give flexible portion provide support, current side pressure sensor 4 sense passenger with
When pressure is suitable between flexible portion, backside pressure sensor issues signal and promotes driving mechanism stop motion, works as backside pressure
When sensor sensing is suitable to the pressure between flexible portion and air bag 8, backside pressure sensor issues signal and promotes to fill
Gas air bag 8 stops inflation.
When the back portion region of user, which is in, contacts state, front side pressure sensor 4 can collect and lean against part
Areal pressure is excessive, and front side pressure sensor 4 issues signal and promotes flexible portion lower slider in lateral driver device and longitudinal direction
It is rearwardly and downwardly moved under the driving of driving device, reduces flexible portion lower knuckle rate, and then make flexible portion far from people
Body back, at the same time, the pressure between backside pressure sensor sensing to flexible portion and air bag 8 increase, and issue letter
Air bag 8 number is promoted to deflate the support for reducing and providing flexible portion, current side pressure sensor 4 senses passenger and flexibility
When pressure is suitable between part, backside pressure sensor issues signal and promotes driving mechanism stop motion, when backside pressure senses
When device senses that the pressure between flexible portion and air bag 8 is suitable, backside pressure sensor issues signal and promotes inflating air
Capsule 8 stops deflating.
In the bending deformation process of flexible portion, after flexible rib bending, the movable block of rolling assembling on flexible rib
It is axially rotated along it to adapt to the differently curved degree of flexible rib, the rubber block between two neighboring movable block rear end is pressed
Contracting, provide support to movable block makes flexible portion be maintained at the bending state to provide certain support force for flexible portion.
In actual use, the setting of the forward N-Side surf of the main back lifting of flexible portion acts on seat in the present invention,
Air bag plays a supportive role, and flexing portions flex deformation is that the curvature of flexible portion can continuously be made to adjust more essence
Really, it is more bonded the back curve of passenger, passenger is made to have higher comfort level.
