That is, the detecting element 4 and the control element 5 in the present invention may be used in cooperation to collectively achieve the self-expanding action of the supporting airbag 31. Specifically, the detection element 4 is electrically connected to the control element 5, so that the detection element 4 can send the detection result to the control element 5, and the control element 5 can analyze and judge the detection result to determine the actual position of the backrest portion 2 relative to the cushion portion 1 according to the detection result. Thus, a specific algorithm can be integrated in the control element 5 to control the inflator 32 to be turned on when the control element 5 analyzes that the relative position of the backrest portion 2 and the cushion portion 1 exceeds the set value according to the detection result, so that the inflator 32 pumps the gas toward the inside of the support airbag 31.

During specific installation, the detection element 4 can be installed on the backrest part 2 to detect the relative position of the cushion part 1 and the backrest part 2 in the movement process of the backrest part 2, or the detection element 4 can be installed on the cushion part 1 to detect the relative position of the backrest part 2 and the cushion part 1. Of course, the detecting elements 4 may be disposed at the backrest portion 2 and the cushion portion 1 at the same time, that is, the detecting elements 4 may be disposed in plural, the detecting elements 4 are disposed at different positions of the seat 100, and the different detecting elements 4 are all electrically connected to the control element 5, so that the different detecting elements 4 detect the relative positions of the backrest portion 2 and the cushion portion 1 at different positions at the same time, and the control element 5 can analyze and determine the detection results of the detecting elements 4, thereby synthesizing the detection results of the detecting elements 4, screening out abnormal data, and more accurately determining the actual relative position between the backrest portion 2 and the cushion portion 1.

Therefore, the automatic control of the supporting air bag 31 can be realized, the accuracy of the control process can be ensured in the automatic control process, the phenomenon that the error of a detection result is overlarge due to the fault of a part of detection elements 4 is avoided, and the supporting air bag 31 is prevented from being opened by mistake. That is, the detecting element 4 of the present invention can be used as an inductive switch of the supporting component 3, and the real-time detection function of the detecting element 4 is utilized to realize the automatic induction function, so as to cooperate with the control element 5 to realize the automatic control process.

Therefore, a new control element 5 does not need to be separately developed or designed, the design cost of the seat 100 is reduced, the number of parts of the seat 100 is reduced, the installation space occupied by the parts is reduced, and the integrated arrangement of the seat 100 is realized. The control element 5 is integrated in the vehicle control unit, and a user can actively operate the state of the inflator pump 32 on the vehicle control unit, so that active intervention of the user is achieved, and the initiative and flexibility of the seat 100 in use are improved.

In some embodiments, the control element 5 comprises a control PCB board, and the control PCB board is disposed on the cushion part 1 or the backrest part 2. That is, the control element 5 can be separately provided, so that the structure of the control element 5 itself is simple, and a complicated program does not need to be provided, thereby being beneficial to reducing the difficulty of the arrangement of the control element 5.

In the specific arrangement, the control PCB, the detection element 4 and the inflator 32 can be arranged adjacent to each other, so that a signal transmission path between the PCB, the detection element 4 and the inflator 32 is short, thereby facilitating improvement of accuracy and corresponding speed of signal transmission.

In some embodiments, the detecting element 4 includes an angle sensor for detecting a rotation angle of the backrest part 2 with respect to the cushion part 1; and/or the detection element 4 includes a displacement sensor for detecting the amount of displacement of the backrest part 2 relative to the cushion part 1.

In some embodiments, the seat 100 further comprises: a manual switch connected to the inflator 32 and adapted to be actuated by a user to control the inflator 32 to selectively turn on. That is to say, the inflator pump 32 in the present invention can not only realize automatic control through the cooperation of the detection element 4 and the control element 5, but also be operated manually by the user, so as to reduce the limitation of automatic control and facilitate to meet the use requirements of the user in a larger scale.

When the chair is specifically designed, the manual switch can be arranged at a position where the hand of a user can conveniently touch, for example, the manual switch is arranged on the left side or the right side of the cushion part 1, so that when the user sits on the chair 100, the hand of the user can be naturally placed at the position where the manual switch is located, and therefore the user can conveniently and actively operate the manual switch, and the manual switch is favorably in control connection with the inflator pump 32 located below the cushion part 1.

In some embodiments, the support assembly 3 further comprises: the air valve switch 35, the air valve switch 35 is disposed on the air pipe 34, and the air valve switch 35 is located between the air storage bag 33 and the support air bag 31. The air valve switch 35 is used for controlling on/off between the air storage bag 33 and the support air bag 31, that is, when the air valve switch 35 is in a closed state, the air storage bag 33 is disconnected from the support air bag 31.

It can be understood that, when the user uses the seat 100 normally, the supporting airbag 31 does not need to be opened, at this time, a large amount of gas is stored in the gas storage bag 33 to serve as a stored gas source, and when the gas valve switch 35 is in the closed state, the gas storage bag 33 is disconnected from the supporting airbag 31, so that the gas flow in the gas storage bag 33 is not easy to enter the supporting airbag 31 automatically, and the supporting airbag 31 is prevented from entering the gas when the seat 100 is in the normal use state. Similarly, when a user lies on the seat 100, the supporting airbag 31 needs to be expanded, and at this time, the air valve switch 35 is in an open state, and the air storage bag 33 is communicated with the supporting airbag 31, so that the air flow in the air storage bag 33 enters the supporting airbag 31 under the action of the inflator 32, and the expanding action of the supporting airbag 31 is realized.

And, it should be noted that, after the inflator 32 pumps the air flow in the air storage bag 33 into the support air bag 31, the support air bag 31 is in an inflated state, at this time, the inflator 32 is not operated, and the air valve switch 35 can be closed, so that the air pressure in the support air bag 31 is kept constant, thereby ensuring that the support air bag 31 is in a stable state when the user lies on the seat 100.

The air valve switch 35 can be electrically connected with the control element 5, so that the control element 5 can directly control the air valve switch 35, and the automatic control function of the air valve switch 35 is realized.

In some embodiments, a storage space is formed at the connection position of the backrest part 2 and the cushion part 1, and the supporting airbag 31 is disposed in the storage space, wherein an elastic stretchable cloth is disposed at the connection position of the backrest part 2 and the cushion part 1, the elastic stretchable cloth is used for shielding the storage space, and the supporting airbag 31 and the elastic stretchable cloth are disposed opposite to each other.

The elastic telescopic cloth can be propped open to deform under the action of external force, and when the external force is removed, the elastic telescopic cloth is recovered to a contraction state. That is, the elastic stretchable cloth is located outside the support airbag 31. Thus, when the support airbag 31 is in the stowed state, the elastic stretchable fabric automatically contracts and shields the support airbag 31 so that the support airbag 31 is not visible from the user's perspective; when the supporting airbag 31 is in the expanded state, the elastic telescopic cloth is expanded under the action of the supporting airbag 31, that is, the elastic telescopic cloth does not interfere with the supporting effect of the supporting airbag 31 on the waist and the hip of the user, so that the structural arrangement of the seat 100 is more reasonable, and the improvement of the use comfort and the safety of the user on the seat 100 is facilitated.
