Description

Technical Field

[0001] This utility model relates to the field of bamboo weaving technology, specifically to a pressure-reducing and breathable bamboo woven cushion. Background Technology

[0002] Bamboo, as a renewable resource, has the characteristics of high strength, good toughness, good thermal conductivity, and natural antibacterial properties. Its fiber structure has its own pores, which naturally have ventilation and breathability. Bamboo weaving is one of my country's traditional handicrafts, in which bamboo is split into strips and made into various woven products. After processing, bamboo strips are suitable as cushion materials for summer or long-term use.

[0003] Traditional seat cushions have poor breathability, leading to stuffiness and heat. Most current mainstream seat cushion materials are primarily sponge, memory foam, and synthetic fabrics, which, while providing some softness, lack breathability. Prolonged sitting can cause stuffiness and sweating due to poor air circulation. While some fabric cushions have breathable surfaces, their internal filling layers create a "closed space," preventing deep air circulation. To achieve pressure relief, some cushions increase thickness or use highly elastic materials, but excessive softness can cause the body to sag, resulting in uneven pressure distribution on the lower back and buttocks. Long-term use may lead to lumbar muscle strain and sciatic nerve compression. Furthermore, many seat cushions made of synthetic materials have issues such as residual odor, easy aging and deformation, and are difficult to degrade after disposal. Summary of the Invention

[0004] The main purpose of this utility model is to provide a pressure-relieving and breathable bamboo woven seat cushion. It aims to utilize bamboo as a natural renewable resource with natural advantages such as high strength, good toughness, good breathability, and environmental degradability. After processing, the bamboo strips are lightweight and have a smooth surface. By designing the woven structure into a seat cushion, the pressure-relieving and breathable properties, tactile comfort, and environmental durability of the seat cushion are improved.

[0005] To achieve the above objectives, this utility model proposes a pressure-reducing and breathable bamboo woven seat cushion, comprising a bottom layer, a middle layer, a top layer, and a support frame. The support frame includes a bottom frame, several support columns, and a top frame. The two ends of the several support columns are respectively fixed to the bottom frame and the top frame. The bottom layer is interwoven and wrapped around and fixed to the bottom frame. One side of the middle layer passes through and is fixed to the edge of the bottom layer, interwoven and wrapped around and fixed to the several support columns. The edge of the top layer passes through and is fixed to the other side of the middle layer, and the top layer is interwoven and wrapped around and fixed to the top frame.

[0006] In an optional embodiment, the top frame is formed by connecting a front beam, two side beams, and a rear beam; the front beam has a protrusion in the middle, the curvature of which conforms to the inner curve of the thigh root; each side beam has two protrusions and two grooves, the protrusions and grooves being alternately distributed along the length of the side beam; the rear beam has a protrusion and two grooves, the protrusions being located between the two grooves; the height of both side beams and the rear beam is higher than the height of the front beam.

[0007] In an optional embodiment, the bottom layer includes a plurality of first bamboo strips, a plurality of second bamboo strips, and a plurality of fixing strips. The plurality of first bamboo strips and the plurality of second bamboo strips are interwoven and woven together, with their ends respectively wrapped and fixed to the opposite side of the bottom frame. The fixing strips fix the interweaving.

[0008] In an optional embodiment, the shape of the interwoven first bamboo strips and the interwoven second bamboo strips, the interlacing and the winding fixation form the supporting thickness of the bottom layer.

[0009] In an optional embodiment, the middle layer includes a plurality of third bamboo strips, each third bamboo strip passing through a corresponding plurality of first bamboo strips or a plurality of second bamboo strips, and interwoven with the plurality of first bamboo strips, the plurality of second bamboo strips and the plurality of support columns, and wrapped and fixed to the top frame.

[0011] In an alternative embodiment, the top layer includes a locking frame located within the top frame and close to the rear beam, with the same height as the front beam.

[0012] In an optional embodiment, the top layer further includes a plurality of fourth bamboo strips, each of which passes through a corresponding plurality of third bamboo strips and interweaves back and forth, and the ends of the plurality of third bamboo strips and the fourth bamboo strips are respectively wrapped around and gathered to the lock frame.

[0013] In an alternative embodiment, a soft pad is installed on the top layer, and a plurality of protrusions are provided in the direction of the top layer, the protrusions being used for pressure reduction and anti-slip.

[0014] In an optional embodiment, several first bamboo strips are interwoven with several second bamboo strips, several first bamboo strips and several second bamboo strips are interwoven with several third bamboo strips, or several third bamboo strips are interwoven with several fourth bamboo strips, forming several ventilation openings evenly arranged between them.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In this utility model, a pressure-reducing and breathable bamboo woven seat cushion is mainly woven from a bottom layer, a middle layer, a top layer, and a support frame. The support frame is ergonomically designed and includes a bottom frame, several support columns, and a top frame. The support columns are fixed to the bottom frame and support the top frame. The top frame is formed by connecting a front beam, two side beams, and a rear beam. The front beam has a protrusion in the middle, and each side beam has two protrusions and two grooves. The protrusions and grooves are alternately distributed along the length of the side beams. The rear beam has a protrusion and two grooves, with the protrusions located between the two grooves. The height of the side beams and the rear beam is higher than the height of the front beam. A number of first and second bamboo strips are interwoven to form a bottom layer, with both ends wrapped around and fixed to the bottom frame. Fixing strips fix the interweaving points of the first and second bamboo strips.

Preferably, the fourth bamboo strips 31 can be bamboo strips with a width of 1-2mm and a thickness of 0.5-0.8mm. The top layer 30 adopts double-layer weaving to achieve thickness and softness, with a 1-2mm gap between the two layers to enhance air circulation, but not limited to this. Preferably, the lock frame 32 can be made of stainless steel or thin-walled steel tubing, which is lightweight and rigid, providing a stable shape reference during weaving, but is not limited to this. Preferably, the lock frame 32 is 10-15cm long and has rounded corners to avoid the anus and perineum, reducing pressure while maintaining breathability, but is not limited to this.

[0034] A plurality of first bamboo strips 11 are interwoven with a plurality of second bamboo strips 12, and a plurality of first bamboo strips 11 and a plurality of second bamboo strips 12 are interwoven with a plurality of third bamboo strips 21, or a plurality of third bamboo strips 21 are interwoven with a plurality of fourth bamboo strips 31, forming a plurality of evenly distributed ventilation openings 50. Preferably, the spacing between the interwoven grids of the plurality of first bamboo strips 11 and a plurality of second bamboo strips 12 is 30mm, the size of the ventilation openings 50 in the bottom layer 10 is 20-22mm, the spacing between the ventilation openings 50 in the middle layer 20 and the top layer 30 is 0.5mm, but not limited to this. Preferably, the first bamboo strip 11, the second bamboo strip 12, the third bamboo strip 21, the fourth bamboo strip 31, and the fixing strip 13 are selected from bamboo species such as light bamboo and water bamboo with a growth cycle of 1-2 years. Their bamboo strip fibers are finer and more resilient. After being made into bamboo strips, they need to be softened by high-temperature steaming for 2 hours in advance and air-dried for 3-5 days to retain their own elasticity. The surface also needs to be polished with fine sandpaper to make it smooth and remove burrs. Beeswax can also be used to lightly rub it to increase smoothness, but it is not limited to this.

[0035] A soft pad 33 is installed on the top layer 30, and several protrusions 33a are provided facing the top layer 30. The protrusions 33a are used for pressure reduction and anti-slip. Preferably, the soft pad 33 can be made of thin pure cotton gauze or linen, with a thickness not exceeding 1mm, to increase surface softness, not to block the perforated structure, and to absorb sweat to prevent the bamboo strips from slipping, but it is not limited to these. Preferably, the protrusions 33a can be made of silicone to reduce local pressure. Silicone is breathable and skin-friendly, but it is not limited to these.

[0036] The working principle of this utility model: A pressure-reducing and breathable bamboo woven seat cushion is mainly woven from a bottom layer 10, a middle layer 20, a top layer 30, and a support frame 40. The support frame 40 is ergonomically designed and includes a bottom frame 41, several support columns 42, and a top frame 43. The support columns 42 are fixed to the bottom frame 41 and support the top frame 43. The top frame 43 is formed by connecting a front beam 43a, two side beams 43b, and a rear beam 43c.

The protrusions and grooves are alternately distributed along the length of the side beam 43b. The rear beam 43c has a protrusion and two grooves. The protrusions are located between the two grooves. The height of the two side beams 43b and the rear beam 43c is higher than the height of the front beam 43a. A number of first bamboo strips 11 and a number of second bamboo strips 12 are interwoven to form a bottom layer 10, with both ends wrapped around and fixed to the bottom frame 41. Fixing strips 13 fix the interweaving points of the first bamboo strips 11 and the second bamboo strips 12. A number of third bamboo strips 21 pass through a number of support columns 42, a number of first bamboo strips 11 and a number of second bamboo strips 12 and interweave to form a middle layer 20. The tail ends of the first bamboo strips 11 and the second bamboo strips 12 are wrapped around and gathered to the top frame 43.
