Description

Technical Field

[0001] This utility model relates to the field of chair technology, and in particular to an ergonomic chair for tailbone protection. Background Technology

[0002] Prolonged sitting can cause pain or soreness in the coccyx, which is quite common in clinical practice. This is mainly due to prolonged sitting in daily life, such as sitting on hard benches for extended periods. The long-term compression and friction of the coccyx can lead to inflammation. To address this, we have proposed an ergonomic chair for coccyx protection.

[0003] Publication (Announcement) No.: CN217243367U discloses an ergonomic chair for coccyx protection, relating to the field of ergonomic chair technology. It includes a seat assembly with a cushion assembly at the bottom. The cushion assembly includes a base plate, and the top of the base plate has several sets of inner pads. Each set of inner pads has several sets of through holes at its top, and a flow channel is provided between adjacent sets of inner pads. A cloth cover is provided on the top of the base plate and outside each set of inner pads. When a user sits on the cushion assembly, if the coccyx is located on the inner pads, the material of the inner pads is elastic gel. The softness and elasticity of the elastic gel effectively reduce pressure on the coccyx caused by prolonged sitting, preventing damage. If the coccyx is located above the flow channel between adjacent sets of inner pads, the inner pads support the area around the coccyx, suspending it in the flow channel, thus also preventing pressure on the coccyx.

[0004] Traditional chairs have fixed backrests, making it inconvenient to adjust the angle of the backrest. Traditional methods use seat cushions to protect the tailbone, but the strength of the seat cushion support cannot be adjusted according to needs. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of traditional chairs where the backrest is fixed and the angle of the backrest is inconvenient to adjust, and the traditional method of using a seat cushion to protect the coccyx where the strength of the seat cushion's support cannot be adjusted according to needs. Therefore, this invention proposes an ergonomic chair with coccyx protection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An ergonomic chair with tailbone protection includes:

[0008] The seat has four chair legs at the bottom, a seat cushion is attached to the top of the seat, the seat cushion has a pre-drilled hole for tailbone protection, and two armrests are symmetrically arranged on the top of the seat.

[0009] The pressure adjustment mechanism is installed on the seat panel and is connected to the seat cushion;

[0010] A backrest adjustment mechanism is provided on the seat panel. A backrest plate is provided on the backrest adjustment mechanism. A backrest pad is provided on the inner side of the backrest plate. A backrest groove is provided on the backrest pad.

[0011] Preferably, the top of the seat panel is provided with an annular hook-and-loop fastener, and the bottom of the seat cushion is provided with an annular textured fastener, the annular hook-and-loop fastener and the annular textured fastener being compatible; this allows for easy assembly and disassembly of the seat cushion.

[0012] Preferably, the seat cushion is provided with a silicone seat cushion and a pressure sensor inside, a hollow rubber ring is embedded in the silicone seat cushion, the pressure adjustment mechanism is connected to the hollow rubber ring, and a breathable elastic mesh is covered on the outside of the seat cushion.

[0013] Preferably, the pressure regulating mechanism includes an air pump installed at the bottom of the seat plate. A pressure valve is connected to the air pump, and a hose is connected to the pressure valve. The hose is connected to a hollow rubber ring. A power distribution box is located at the bottom of the seat plate, and a controller is located on the outside of the power distribution box. A control chip is connected to the controller and is located inside the power distribution box. The control chip calculates the pressure value of the pressure sensor, and the controller controls the air pump to work, inflating the hollow rubber ring, increasing the pressure, and improving the support strength of the seat cushion.

[0014] Preferably, the backrest adjustment mechanism includes two fixing blocks, both of which are fixedly installed on the top of the seat plate. The inner side of each of the two fixing blocks is provided with a circular groove, and a rotating rod is rotatably installed in each of the two circular grooves through a bearing.

[0016] The beneficial effects of the ergonomic chair for tailbone protection described in this utility model are as follows:

[0017] This design involves sitting on the top of the cushion, which supports the user's buttocks. The coccyx protection hole protects the user's coccyx. A pressure sensor monitors the pressure value inside the cushion. If a heavier person sits on the top of the cushion, the pressure sensor reading increases. Sitting on the top of the cushion causes the coccyx to shift downwards, triggering the air pump and opening the pressure valve. This inflates the hollow rubber ring inside the cushion through a hose, increasing the cushion's support strength and ensuring the coccyx remains suspended.

[0018] This solution uses a servo motor to drive a drive gear to rotate. The drive gear and the driven gear work together to drive a rotating rod to rotate. The rotating rod drives the backrest to rotate through two flipping blocks, which can adjust the support angle of the backrest. The backrest pad supports the user's back through the back groove. When the backrest is laid flat, it can be used by the user to lie down and meet the needs of office rest.

[0019] This invention has good performance and can protect the coccyx. The support strength of the seat cushion can be adjusted for different people to ensure that the coccyx is suspended. The angle of the backrest can be adjusted and it can also be used by lying down. Attached Figure Description

[0033] Reference Figure 5 , Figure 6 In this embodiment, the top of the seat plate 1 is provided with an annular hook-and-loop surface sticker 21, and the bottom of the seat cushion 3 is provided with an annular textured surface sticker 22. The annular hook-and-loop surface sticker 21 and the annular textured surface sticker 22 are compatible, which makes it easy to assemble and disassemble the seat cushion 3.

[0034] Reference Figure 2 , Figure 5 , Figure 6 In this embodiment, the seat cushion 3 is provided with a silicone seat cushion and a pressure sensor inside. A hollow rubber ring is embedded in the silicone seat cushion. The pressure adjustment mechanism is connected to the hollow rubber ring. A breathable elastic mesh is covered on the outside of the seat cushion 3.

[0035] Reference Figure 2 , Figure 6In this embodiment, the pressure regulating mechanism includes an air pump 13, which is installed at the bottom of the seat plate 1. A pressure valve 14 is connected to the air pump 13, and a hose 15 is connected to the pressure valve 14. The hose 15 is connected to a hollow rubber ring. A power distribution box 11 is provided at the bottom of the seat plate 1, and a controller 12 is provided on the outside of the power distribution box 11. A control chip is connected to the controller 12 and is located inside the power distribution box 11. The controller 12 calculates the pressure value of the pressure sensor through the control chip, and controls the air pump 13 to work, inflating the hollow rubber ring, increasing the pressure, and improving the support strength of the seat cushion 3.

[0036] Reference Figure 7 , Figure 8 In this embodiment, the backrest adjustment mechanism includes two fixing blocks 6, both of which are fixedly installed on the top of the seat plate 1. A circular groove 26 is formed on the inner side of each of the two fixing blocks 6. A rotating rod 17 is rotatably mounted in each of the two circular grooves 26 via bearings. Two flipping blocks 16 are fixedly installed on the outer side of the rotating rod 17. A common backrest plate 7 is mounted on each of the two flipping blocks 16. A protective shell 25 is fixedly installed on the top of the seat plate 1. A servo motor 20 is installed on the inner wall of the protective shell 25.

[0037] Working principle: When in use, connect the power supply and controller 12 (which can perform electrical control, but this is existing technology and will not be described in detail here). Sit on the top of the cushion 3. The cushion 3 supports the user's buttocks. The coccyx protection hole 4 is used to protect the user's coccyx, allowing the coccyx to be suspended 3-5cm above the ground. The pressure sensor monitors the pressure value inside the cushion 3. If a heavier person sits on the top of the cushion 3, the pressure value of the pressure sensor increases. Sitting on the top of the cushion 3 will cause the coccyx to move downward. The air pump 13 will work, and the pressure valve 14 will open. The hollow rubber ring inside the cushion 3 will be inflated through the hose 15, causing the hollow rubber ring to expand and increasing the support strength of the cushion 3, ensuring that the coccyx is suspended 3-5cm above the ground. For example, if the pressure increases by 10kg, according to the pressure formula P=F / S, substituting F=9.8*10=98N and S=0.2 square meters (approximately the force-bearing area of ​​a cushion), we get P=490Pa.

[0038] The servo motor 20 drives the drive gear 19 to rotate. The drive gear 19 and the driven gear 18 work together to drive the rotating rod 17 to rotate. The rotating rod 17 drives the backrest 7 to rotate through two flipping blocks 16, which can adjust the support angle of the backrest 7. The backrest pad 8 supports the user's back through the back groove 9. When the backrest 7 is laid flat, it can be used by the user to lie down and meet the needs of office rest.
