Abstract

In an embodiment, there is provided a chair including: a chair body; at least one sensing element on the chair body for sensing a human body pressure on the chair body; at least one gasbag on the chair body for supporting a waist of a human body; a gas pump for performing inflation and deflation of the at least one gasbag; and a control assembly in signal connection with the at least one sensing element for controlling the gas pump to perform inflation and deflation of the at least one gasbag according to information acquired by the sensing element.

Claims

1. A chair comprising:

a chair body;

at least one sensing element on the chair body configured for sensing a human body pressure on the chair body;

at least one gasbag on the chair body configured for supporting a waist of a human body;

a gas pump operable for performing inflation and deflation of the at least one gasbag; and

a control assembly in signal connection with the at least one sensing element for controlling the gas pump to perform inflation and deflation of the at least one gasbag according to information acquired by the sensing element.

2. The chair of claim 1, wherein the chair body comprises a chair frame and a lumbar pillow, and the at least one gasbag is between the chair frame and the lumbar pillow.

3. The chair of claim 2, wherein the at least one sensing element comprises a plurality of sensing elements on the chair frame.

4. The chair of claim 3, wherein the chair frame comprises a backboard and a seat board, and both the backboard and the seat board are provided with the sensing elements.

5. The chair of claim 4, wherein the backboard and the seat board are respectively provided with two to four of the sensing elements, and the sensing elements are substantially symmetrically arranged along a central line of the chair body.

6. The chair of claim 4, wherein the at least one gasbag comprises a plurality of gasbags respectively on the backboard and the seat board.

7. The chair of claim 1, further comprising a manual control switch connected to the gas pump and configured for manually performing inflation and deflation of the at least one gasbag.

8. The chair of claim 1, wherein the control assembly comprises:

a data processor for processing the information from the at least one sensing element and outputting an electrical signal, and a memory in signal connection with the data processor for storing user data.

9. The chair of claim 8, wherein the chair body is provided with an identification device for identifying different users.

10. The chair of claim 9, wherein the control assembly is configured for:

retrieving the user data stored in the memory according to an identification of user identified by the identification device, and controlling the gas pump to perform inflation and deflation of the at least one gasbag according to the user data.

11. The chair of claim 9, wherein the identification device comprises at least one of a fingerprint identification device, a face identification device and a barcode identification device.

12. A smart lumbar pillow system for chair, comprising:

at least one sensing element on a chair body configured for sensing human body pressure on the chair body;

at least one gasbag on the chair body configured for supporting a waist of a human body;

a gas pump operable for performing inflation and deflation of the at least one gasbag; and

a control assembly in signal connection with the at least one sensing element and the gas pump.
