Description

Technical Field

[0001] This utility model belongs to the field of seating technology, specifically relating to a gel seat cushion suitable for chairs. Background Technology

[0002] Primary and secondary school students are in a stage of growth and development, and their bodies are more susceptible to the effects of poor posture than adults, easily leading to fatigue and harming their development and physical health. This can affect their bones and joints, and in severe cases, cause spinal deformities. Therefore, patent publication number CN 218355276U discloses a lumbar support and posture correction cushion, which includes a seat cushion, a connecting part, and a backrest connected in sequence. The seat cushion, connecting part, and backrest are integrally injection molded into a single structure. The end of the seat cushion away from the connecting part has an upwardly raised ridge, which extends in an arc shape to both sides. The two sides of the seat cushion curve upward, and the ridge and the two sides of the seat cushion form recesses respectively. The two sides of the backrest extend forward in an arc shape to form a covering structure. The middle of the backrest has an opening, and an elastic support arm is provided at the opening. One end of the elastic support arm is connected to the lower wall of the opening, and the other end of the elastic support arm protrudes forward from the opening. Ultimately, by adopting an ergonomic design, the lumbar support and posture correction cushion fits the waist better. The backrest's curved design is perfectly suited to the waistline of each user, fully leveraging the cushion's function of correcting posture.

[0003] However, in practical applications, the above-mentioned seat cushions only take into account the fit with the human body, but ignore the fact that both the seat cushion and the chair are made of relatively hard materials. Not only can the seat cushion not fit the chair completely, but it also makes it impossible for the human body to sit stably on the chair with the help of the seat cushion. In the long run, it is impossible to distribute the pressure of sitting for a long time. Instead, the human body will feel tired and oppressed because it needs to maintain balance all the time. Utility Model Content

[0004] The purpose of this invention is to provide a gel seat cushion suitable for chairs, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gel seat cushion suitable for chairs, comprising a seat cushion body, the seat cushion body having a seat cushion portion, a lumbar support portion, and a backrest, characterized in that the lumbar support portion has symmetrically opened first heat dissipation holes, the top of the seat cushion portion is provided with a first buffer zone, the first buffer zone specifically being a T-shaped pad and a first pad symmetrically arranged with the T-shaped pad as the center, the left and right sides of the T-shaped pad forming a first heat dissipation channel with the first pad, the first pad having a second heat dissipation hole, and the front side of the backrest is provided with a second buffer zone, the second buffer zone specifically being a V-shaped pad and a second pad symmetrically arranged with the V-shaped pad as the center, the left and right sides of the V-shaped pad forming a second heat dissipation channel with the second pad.

[0006] Preferably, the upper edge of the backrest is recessed inward to form a gap area.

[0007] Preferably, the front side of the seat cushion is in a horizontal position.

[0008] Preferably, the seat cushion body is integrally molded and has a rounded "L" shape.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figures 1 to 4The image shows a gel seat cushion for a chair. The cushion body 1 includes a seat portion 2, a lumbar support portion 3, and a backrest 4. The lumbar support portion 3 has symmetrically arranged first heat dissipation holes 5. The top of the seat portion 2 has a first buffer zone 6, which specifically consists of a T-shaped pad 601 and first pads 602 symmetrically arranged around the T-shaped pad 601. The left and right sides of the T-shaped pad 601 and the first pads 602 form first heat dissipation channels 603. The first pads 602 have second heat dissipation holes 604. The front side of the backrest 4 has a second buffer zone 7, which specifically consists of a V-shaped pad. 701 and a second pad 702 symmetrically arranged with the V-shaped pad 701 as the center, the left and right sides of the V-shaped pad 701 and the second pad 702 form a second heat dissipation channel 703; the upper edge of the backrest 4 is recessed inward to form a partition area 8; the front side of the seat cushion 2 is horizontal; the seat cushion body 1 is integrally molded and presents a rounded "L" shape; a third heat dissipation hole 9 is opened on the T-shaped pad 601; the first heat dissipation channel 603 and the second heat dissipation channel 703 are both connected to the lumbar support 3 inward and are open outward; the first buffer zone 6 and the second buffer zone 7 are both made of gel material.

[0026] This invention utilizes an integrally molded "L"-shaped structure to provide a stable structure and precise human body support, reducing discomfort caused by seat cushion wobbling or shifting. Simultaneously, the forward-convex design of the lumbar support 3 helps maintain the natural S-curve of the spine, better conforming to the human body's curves, reducing lumbar pressure, and preventing problems such as lumbar disc herniation. The front of the seat cushion 2 is horizontal, allowing the cushion to perfectly conform to the chair surface, providing stable support and avoiding instability caused by improper seat cushion shape. Furthermore, the backrest 4 of this invention reduces the inward twisting range, allowing the backrest 4 to... The design better conforms to the chair surface, while the separated backrest 4 on both sides better conforms to the user's shoulder blades, providing a stable sitting posture. This utility model effectively dissipates heat generated inside the seat cushion by opening heat dissipation holes and forming heat dissipation channels in the lumbar support 3, the first cushion 602, and the T-shaped cushion 601, reducing the stuffiness of the waist and back and keeping the backrest surface cool. This utility model also uses gel material to prepare the first buffer zone 6 and the second buffer zone 7, giving them good support, resilience, and heat dissipation, and can conform to the shape of the human buttocks, effectively dispersing the pressure caused by sitting posture and reducing the harm to the body from prolonged sitting.

[0027] Example 2

[0028] like Figures 1 to 4The illustrated gel seat cushion for chairs includes a seat body 1. The seat body 1 has a seat cushion portion 2 that contacts the legs and buttocks, a lumbar support portion 3 that contacts and supports the waist, and a backrest portion 4 that contacts the back. The seat cushion portion 2, lumbar support portion 3, and backrest portion 4 are integrally molded, presenting a rounded "L" shape. This makes the structure of the seat body 1 more stable and less prone to deformation, and can withstand the use of users of most weight sizes on the market. Users can feel more stable support when using it, reducing discomfort caused by the shaking or displacement of the seat body 1. At the same time, the integral molding design allows the seat cushion to better conform to the curves of the human body, providing more precise support.

[0029] In this invention, the front of the seat cushion 2 is horizontal, and the entire seat cushion 2 is nearly straight. Compared to common posture-correcting seat cushions, the horizontal seat cushion 2 of this invention is more suitable for use on chairs. Most chairs are vertical and hard, and existing posture-correcting seat cushions, considering leg support and leg separation to prevent users from crossing their legs and ultimately to correct and cultivate good posture, often design the front of the seat cushion 2 to extend upwards on both sides in a wrapping shape, while the middle part bulges upwards, making the entire seat cushion 2 present a rounded "W" shape. This shape, when in contact with the flat surface of the chair, not only cannot fit completely against the chair, but also makes it difficult for the body to sit stably on the chair with the support of the seat cushion. In this embodiment, however, the seat cushion 2 in the seat cushion body 1 is horizontal, which allows it to fit perfectly against the chair with the user's weight, making it more convenient to use.

[0030] This embodiment also uses the forward-convex design of the lumbar support part 3 to help the user's spine present a natural S-shaped curve. The seat cushion provides close support to the lumbar spine, relieves lower back discomfort, and guides the user to maintain the correct lumbar posture. When the user sits on the seat cushion, the lumbar support part 3 will give the lower back an upward push, so that the user can sit up naturally, reduce the pressure on the lumbar spine, and prevent problems such as lumbar disc herniation.

[0031] Furthermore, when a user sits on the chair using the cushion, they will lean their back against the backrest 4. Common posture-correcting cushions also adopt a design that extends and bends outwards on both sides, forming a wrap-around shape, while the central curve extends forward. The overall twisting arc is relatively large, which is intended to cause both sides to wrap inwards when the user applies force to the backrest 4, thus protecting the back. However, the above design is still not suitable for chairs. After contacting the flat surface of the chair, it cannot fully fit the chair and the central curve cannot be offset, causing discomfort to the user. Consequently, the user's back cannot be stably supported by the seat cushion. Based on the above background, although the backrest 4 in this embodiment is also wrapped, the inward twisting amplitude is reduced. With the user's weight, the backrest 4 can be driven to fit perfectly against the chair. At the same time, the forward-extending central curve is reduced, and the upper edge of the backrest 4 is recessed inward to form a gap area 8. In this way, the backrest 4 can be divided into two halves, reducing the contact area between the central curve and the chair, making the entire backrest 4 fit the flat surface of the chair better. At the same time, the two sides of the separated backrest 4 will better fit the user's shoulder blades, allowing the user to sit stably on the seat cushion body 1 and the chair.

[0032] Example 3

[0033] like Figures 1 to 4 The gel seat cushion shown includes a seat body 1, which has a seat cushion part 2 that contacts the legs and buttocks, a lumbar support part 3 that contacts and supports the waist, and a backrest 4 that contacts the back. The seat cushion part 2, the lumbar support part 3, and the backrest 4 are integrally molded and have a rounded "L" shape. The seat cushion body 1 can be made of materials with strong support and high elasticity, such as polypropylene (PP) and polyurethane (PU). In addition to providing support, its comfort also depends on the cushioning surface set on the surface of the seat cushion body 1.

[0034] The top of the seat cushion 2 is provided with a first buffer zone 6, which specifically consists of a T-shaped cushion 601 and a first cushion 602 symmetrically arranged around the T-shaped cushion 601. The front side of the backrest 4 is provided with a second buffer zone 7, which specifically consists of a V-shaped cushion 701 and a second cushion 702 symmetrically arranged around the V-shaped cushion 701. When people sit for extended periods, their lumbar spine, back, thighs, and hips are easily subjected to pressure, leading to fatigue and a feeling of pressure. The first buffer zone 6 and the second buffer zone 7 allow the seat cushion body 1 to better conform to the curves of the human body, providing support or distributing pressure, thus reducing discomfort from prolonged sitting and improving comfort.

[0035] The first buffer zone 6 and the second buffer zone 7 can be made of soft, comfortable materials such as high-density memory foam, sponge, polyester fiber, cotton and linen fabric, and gel, which provide moderate support and effectively conform to the curves of the human body. However, considering the usage scenario of this embodiment, where the user needs to sit for a long time, the material of the first buffer zone 6 and the second buffer zone 7 is limited to gel. Gel itself has a cool touch, which can help the user's body maintain a comfortable temperature for a long time and has good heat dissipation. In addition, gel material also has excellent support and resilience. Regardless of the user's body shape, it can conform to the shape of the buttocks, effectively dispersing the pressure caused by sitting posture, reducing the harm to the body from prolonged sitting, and providing a more comfortable experience. Its good resilience allows the cushion to quickly return to its original shape even after long-term use, maintaining the durability of the cushion.

[0036] Furthermore, the gel pad uses a honeycomb arrangement, giving the gel seat multiple support points that can share the user's weight, reducing pressure on the buttocks during long periods of sitting and alleviating the damage caused by prolonged sitting. The honeycomb arrangement also gives the seat body 1 a large number of air holes, which helps air circulation, reduces sweat accumulation, keeps it cool even after long-term use, and reduces bacterial growth and odor.

[0037] Furthermore, the lumbar support 3 has symmetrically arranged first heat dissipation holes 5, the first cushion 602 has a second heat dissipation hole 604, and the T-shaped cushion 601 has a third heat dissipation hole 9. These features dissipate heat generated inside the seat cushion body 1, effectively reducing stuffiness in the waist and back, keeping the backrest surface cool, and improving comfort. Simultaneously, first heat dissipation channels 603 are formed between the T-shaped cushion 601 and the first cushion 602 on both sides, and second heat dissipation channels 703 are formed between the V-shaped cushion 701 and the second cushion 702 on both sides. Both the first and second heat dissipation channels 603 and 703 are connected inward to the lumbar support 3 and open outward. This allows heat accumulated after prolonged sitting to flow outward through these channels, carrying away heat, lowering the surface temperature of the seat cushion body 1, keeping it dry after prolonged sitting, and reducing bacterial growth.
