Description

Technical Field

[0001] This utility model belongs to the field of seat cushion technology, specifically relating to a high-support rigid seat cushion structure. Background Technology

[0002] Seat cushions are common items in people's daily lives. With the widespread use of computers, many office workers need to sit in front of computers for long periods of time. Prolonged sitting not only leads to fatigue but can also damage the spine, lumbar vertebrae, and sciatic nerve, and in severe cases, may even cause hemorrhoids, prostatitis, and other diseases. Traditional seat cushions are relatively simple in design and lack lumbar support, failing to effectively alleviate these health problems. Therefore, people have developed new lumbar support seat cushions. When existing seat cushions are too soft, prolonged sitting can cause muscle relaxation in the buttocks, thighs, and other areas, affecting the body's strength and stability. Utility Model Content

A soft leather bump 12 is installed at the center line of the sub-frame 3. The soft leather bump 12 is filled with sponge 13. The seat cushion frame 1 is glued to fix the sub-frame 3. The sub-frame 3 is made of ABS material. The cushioning pad 8 is made of hydrogel material. The air cushion 9 is made of TPU material. The soft leather covering layer 11 is made of PU leather material.

[0021] Through the above technical solution, the seat cushion frame 1 of this utility model is fixedly installed with a secondary frame 3. The secondary frame 3 improves the rigidity of the seat cushion. The secondary frame 3 is provided with a connecting column 4. The connecting column 4 is provided with a slot 5. The connecting column 4 is elastically connected to a small support plate 7 through a spring 6. A cushioning pad 8 is fixedly installed on the end face of the small support plate 7. An air cushion 9 is fixedly connected to the secondary frame 3. The bottom of the air cushion 9 is provided with a concave hole 10. The end face of the cushioning pad 8 abuts against the top of the concave hole 10. The spring 6 provides support force to the small support plate 7. The cushioning pad 8 is applied to the air cushion 9, so that the seat cushion has elastic cushioning and high support force, preventing muscle relaxation problems in the buttocks, thighs and other parts caused by prolonged sitting.

[0022] This utility model has a soft leather bump 12 installed at the center line of the sub-frame 3. The soft leather bump 12 is filled with sponge 13. When the user sits on the cushion, the buttock groove fits into the soft leather bump 12 to prevent hemorrhoids caused by prolonged sitting.

[0023] Example 2:

[0024] like Figures 1-5As shown, this utility model includes a seat cushion frame 1 and a backrest frame 2. The seat cushion frame 1 and the backrest frame 2 are manufactured using an integrated molding process to ensure the stability and load-bearing capacity of the overall structure. A sub-frame 3 is fixedly installed on the seat cushion frame 1. The sub-frame 3 is made of ABS material and provides additional support and rigidity. The sub-frame 3 has multiple connecting posts 4, each with a slot 5. The connecting posts 4 are elastically connected to a small support plate 7 via springs 6, forming a support system. A cushioning pad 8 is fixedly installed on the end face of the small support plate 7. The cushioning pad 8 is made of hydrogel material and has good shock absorption and pressure dispersion effects. The sub-frame 3 is fixedly connected to an air cushion 9. The air cushion 9 is made of TPU material and provides additional elastic support. The bottom of the air cushion 9 has multiple recesses 10, which abut against the end face of the cushioning pad 8 to form a composite cushioning structure. A soft leather wrapping layer 11 is fixedly connected to the outer surface of the air cushion 9. The soft leather wrapping layer 11 is made of PU leather material and provides a comfortable touch and durability. A soft leather bump 12, filled with sponge 13, is installed at the center line of the sub-frame 3, providing extra support and comfort for the user's buttocks. This structural design combines rigid support with multi-layered cushioning, ensuring both the cushion's support and providing necessary elasticity and pressure distribution. The cushion frame 1 and sub-frame 3 are bonded together with high-strength adhesive to ensure structural stability. The spring 6 connecting the connecting column 4 and the small support plate 7 allows for slight vertical movement, further enhancing the cushion's comfort. The combined design of the cushioning pad 8 and the air cushion 9 with its recessed holes 10 enhances the overall shock absorption, helping to reduce the pressure on the body caused by prolonged sitting. The soft leather bump 12 is specifically designed to provide support for the buttocks, helping to maintain correct posture and reduce localized pressure. The overall structure comprehensively considers support, comfort, and health factors, providing an ideal cushion solution for people who sit for long periods of time while working or resting.

[0025] Example 3:

[0026] The connection between the seat cushion frame 1 and the sub-frame 3 in this invention is achieved by bonding and fixing with high-strength epoxy resin adhesive. This bonding method ensures a strong bond between the seat cushion frame 1 and the sub-frame 3, enhancing the stability and durability of the overall structure. The sub-frame 3 is made of ABS (acrylonitrile-butadiene-styrene copolymer), a material with excellent mechanical strength, impact resistance, and dimensional stability. The ABS sub-frame 3 can withstand various stresses and loads during daily use while maintaining good shape retention. During the bonding process, clamps are used to position and fix the seat cushion frame 1 and the sub-frame 3, ensuring a tight fit between the bonding surfaces. The adhesive is applied evenly, covering the entire contact surface, avoiding air bubbles or unbonded areas. The bonded structure undergoes a constant-temperature drying process to ensure complete curing of the adhesive and achieve optimal bonding strength. The ABS sub-frame 3 not only provides additional support but also has good anti-aging properties, maintaining good performance over long-term use.

[0027] Example 4:

[0028] The cushioning pad 8 of this invention is made of hydrogel material. This material provides excellent shock absorption and pressure dispersion properties. The hydrogel cushioning pad 8 is manufactured using a mold, ensuring that each pad is the same size and shape. The hydrogel material has good elasticity and resilience, allowing it to quickly return to its original shape after being compressed, maintaining its cushioning effect over long-term use. The surface of the cushioning pad 8 undergoes special treatment to increase its adhesion to the small support plate 7, ensuring it will not detach during use. The hydrogel material also has a certain temperature regulation capability, absorbing and slowly releasing heat to improve the comfort of the seat cushion.

[0029] Example 5:

[0030] The air cushion 9 of this invention is made of TPU (thermoplastic polyurethane elastomer). TPU material has excellent elasticity, abrasion resistance, and aging resistance, making it suitable for manufacturing air cushions 9 that need to maintain elasticity for a long time. This ensures that the shape and thickness of the air cushion 9 are uniform. The TPU material air cushion 9 has good airtightness, enabling it to maintain its inflated state for a long time and maintain a stable support effect.

[0031] Example 6:

[0032] The soft leather wrapping layer 11 of this invention is made of PU (polyurethane) leather. PU leather has excellent wear resistance, flexibility, and aging resistance, making it suitable for use as a surface material for seat cushions used for extended periods. The soft leather wrapping layer 11 is manufactured using precision cutting and sewing processes to ensure that the size and shape of each wrapping layer precisely match the seat cushion structure. The PU leather material undergoes special treatment to increase breathability and improve comfort during prolonged use. The surface of the soft leather wrapping layer 11 features a fine texture design, providing a comfortable touch while increasing anti-slip properties. The edges of the wrapping layer are double-stitched, enhancing the durability and aesthetics of the structure. The PU leather material has good waterproof properties, facilitating daily cleaning and maintenance. The soft leather wrapping layer 11 is fixed to the air cushion 9 with a high-strength adhesive, ensuring that it will not wrinkle or detach during use.
