[0010] When using the chair, the user first adjusts the seat height. After adjusting to the appropriate height, the inflatable element is connected to the external power supply. Once connected, the chair can be used. When the user sits on the seat, the airbag element on the seat plate senses the pressure according to the user's sitting posture. As the inflatable element works, the airbag element begins to inflate and supports the user's legs or legs while sitting.

[0011] Beneficial effects obtained:

[0012] It is equipped with an airbag component and an inflatable component, which can effectively sense the received pressure through the airbag component, and inflate the airbag component through the work of the inflatable component, and through the expansion of the airbag component, the airbag component can effectively support the legs or buttocks of the person. The seat cushion cover can effectively wrap and protect the outside of the airbag component to prevent external damage to the airbag component. The seat cushion cover is detachable for easy cleaning later. The filling layer can absorb impact and pressure, so that the seat cushion provides a comfortable sense of support.

[0017] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0018] Example:

[0019] Reference Figures 1 to 3The present application is a chair with an adaptive seat cushion, comprising a seat 1, a leg 2 and a backrest 3. The seat 1 is installed on the leg 2 in a manner that allows it to be raised and lowered and rotated. A gas rod is provided between the seat 1 and the leg 2, and the seat 1 is raised and lowered by the gas rod. The top of the gas rod is rotatably connected to the bottom of the seat 1 through an installed bearing to increase the rotation function of the seat. The backrest 3 is provided on the seat 1 and is located on one side of the seat 1. An L-shaped connecting block with a certain elastic force is provided between the backrest 3 and the seat 1 for connection, so that the backrest 3 has a certain range of motion relative to the seat 1.

[0020] like Figure 2 and Figure 3 As shown, the chair seat 1 is provided with a seat plate 4, and the seat plate 4 is provided with an airbag component for sensing support. The airbag component includes a number of elastic support sponges 7, a number of airbag bags 8 and a number of pressure sensors 9. A number of mounting grooves 18 are evenly opened on the seat plate 4. One end of a number of support sponges 7 is respectively fixed in the corresponding mounting groove 18, and the other ends of a number of support sponges 7 extend out of the corresponding mounting groove 18. A number of airbag bags 8 are fixed one by one to one of the ends of a number of support sponges 7 extending out of the mounting groove 18. It is worth mentioning that the number of airbag bags 8 are evenly distributed on the seat plate 4 along the direction of the chair back 3 like the word "Chuan". The middle height of the number of airbag bags 8 is greater than the height on both sides. Buffer grooves 10 are opened between the number of support sponges 7 and the bottom of the corresponding mounting groove 18. A number of pressure sensors 9 are respectively fixed at the bottom of the number of mounting grooves 18 and are located in the corresponding buffer grooves 10. The seat 1 is provided with an inflatable element for inflating the airbags. A protective cover 13 is provided at the bottom of the seat plate 4 to house the inflatable element. The inflatable element includes several inflatable pumps 11 and control units 12 for controlling each of the inflatable pumps 11. Each of the inflatable pumps 11 is located at the bottom of the seat 1 and communicates with each of the airbag packages 8. The control unit 12 is mounted at the bottom of the seat plate 4. The pressure sensors 9 are configured to send signals to the control unit 12. The control connection between the control unit 12 and the inflatable pumps 11 utilizes conventional chip control, primarily electrical connections. The detailed principles of this arrangement will not be elaborated upon herein. This arrangement allows the support sponge 7 to move downward and contact the pressure sensors 9 when a person is seated. This pressure sensor 9 transmits a signal to the control unit 12, which then controls the operation of the inflatable pumps 11 and inflates the airbag packages 8. During inflation, the airbags 8 are constrained at their lower position and their sides are lower than their center. Therefore, the airbags expand upward during inflation, effectively supporting the legs or buttocks of the person.

[0021] like Figure 2 and Figure 3As shown, the seat panel 4 has a removable cover with a cushion cover 5, and several airbag packages 8 are located within the cushion cover 5. Several latches 14 are located at the bottom of the seat panel 4, and several buckles 15 are located at the ends of the cushion cover 5. The buckles 15 correspond to and engage with the latches 14 in a one-to-one manner. This snap-on connection structure is similar to the existing press buckle 15 structure. A Velcro layer 16 is located at the bottom of the seat panel 4, and a Velcro layer 17 is provided on the seat cover 5 to adhere to the Velcro layer 16. This arrangement effectively strengthens the connection between the cushion cover 5 and the seat panel 4 through two connections. A filling layer 6 is provided between the airbag assembly and the cushion cover 5. The filling layer 6 is made of silicone gel and is primarily located on both sides of the airbag package 8 within the cushion cover 5. It does not affect the expansion of the airbag package 8.

[0022] How it works

[0023] When in use, the user can first adjust the height of the seat 1 of the chair by using the gas rod. After adjusting to the appropriate height, the control unit 12 is connected to the external power supply. After the connection is completed, the user can use it. When the user sits on the seat 1, the pressure sensor 9 senses the pressure according to the user's sitting posture and transmits a signal to the control unit 12. The control unit 12 controls the operation of different air pumps 11 and inflates the airbags 8 in the pressure-receiving position to support the user's legs.
