The angle ɑ between the arc frame 12 and the elastic rod 20 is an obtuse angle, so that the two arc frames 12 are respectively opened to both sides in an inverted "eight" shape relative to the elastic rod 20. The elastic cushion skeleton described in the utility model is wrapped with an outer cover on the outside to be used as a backrest or seat cushion, or is placed under a flexible interlayer such as a sponge or a flexible pad, and is suitable for office seats, car seats, sofas, etc. The two support frames 10 support the back, lower back or buttocks of a person through the outer cover or flexible interlayer, making the user feel comfortable, and having good ventilation and air permeability and heat dissipation, and a good use experience. The user can regularly disassemble the outer cover or flexible interlayer for cleaning and drying, keep it clean, prevent bacteria from growing, and be beneficial to health. The two arc-shaped frames extending in an inverted "eight" shape support and tighten the outer cover. When in use, the back, lower back or buttocks of a person touch the outer cover, but not the elastic cushion frame 1, and there is no feeling of hardness. The two arc-shaped frames extending in an inverted "eight" shape protect the human body from the back, lower back or buttocks of a person, further increasing the comfort and sense of security of the user.

[0038] Preferably, a plurality of first reinforcing connectors 14 are provided on the arc-shaped frame 12 and the main side rod 11. The first reinforcing connector 14 may be a rod-shaped or sheet-shaped with a circular, elliptical or quadrilateral cross-section. The function of the first reinforcing connector 14 is to strengthen the connection strength between the arc-shaped frame 12 and the main side rod 11 so that the first reinforcing connector 14 can withstand greater pressure.

[0039] Preferably, a plurality of mounting seats 17 are provided on the top surface of the main side rod 11 , and the mounting seats 17 correspond to the first reinforcing connectors 14 one by one, and each of the first reinforcing connectors 14 is connected to one side of the mounting seat 17 .

[0040] The mounting seat 17 is provided with an insert tube 15a on the opposite side of the first reinforcing connector 14, and one end of each elastic rod 20 is inserted into the insert tube 15a, so as to facilitate the installation and disassembly of the elastic rod 20. When transporting and storing the elastic cushion skeleton 1, the elastic rod 20 and the support frame 10 can also be packaged separately, which saves space and reduces transportation and storage costs.

[0041] It should be understood that the end of the elastic rod 20 matches the shape of the plug-in tube 15a, so that after the end of the elastic rod 20 is inserted into the plug-in tube 15a, the structure is stable and the elastic rod 20 will not rotate or slide. Preferably, the end of the elastic rod 20 is flat, and the tube mouth of the plug-in tube 15a is also flat.

[0042] Preferably, the plug-in tube 15a is arranged on the top of the mounting seat 17, so that after the elastic rod 20 is installed, there is a vertical distance H between it and the plane where the bottom surface of the main side rod 11 is located, forming a storage space 19, which can be used to place health products such as sachets and medicine bags.
