Description

Technical Field

[0001] This utility model relates to the field of seat cushion technology, specifically to an ergonomic memory foam seat cushion. Background Technology

[0002] Memory foam, also known as slow rebound foam or space foam, is scientifically called polyurethane slow rebound foam. It is a high-density viscoelastic material that is sensitive to temperature and pressure. When compressed, it gradually conforms to the shape of the object applying the pressure, and after the pressure is removed, it slowly returns to its original shape. It can conform to the curves of the body, and its excellent pressure distribution is suitable for protruding parts such as the shoulders and hips, reducing the feeling of pressure.

[0003] Most ergonomic memory foam seat cushions are of a fixed size. To match the seat depth, users need to choose a seat cushion that can fully support the buttocks and provide adequate support for the thighs when purchasing. If the seat depth is too deep, users will unconsciously curl up backward in order to lean against the backrest, resulting in the lumbar spine being unsupported and hunching over. If the seat depth is too shallow, most of the thighs will be unsupported, and the ischial tuberosities will become the only pressure point, which will quickly lead to soreness and numbness in the buttocks.

[0004] This case arose in order to resolve the aforementioned issues. Summary of the Invention

[0005] Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides an ergonomic memory foam seat cushion, which solves the problems mentioned in the background section.

[0006] Technical solution To achieve the above objectives, this utility model is implemented through the following technical solution: an ergonomic memory foam seat cushion, including a base and a second base, the base having an upwardly extending backrest, the base, backrest, and second base having memory foam layers, the base having a guide box, the second base having a connecting slider, and the guide box and the connecting slider being slidably connected.

[0007] Preferably, the guide box has guide grooves on both sides, and a stop tooth with evenly spaced graduations is provided below the guide groove. The left side of the stop tooth is arc-shaped. The connecting slider has limit wheels on both sides, and the limit wheels are rotatably connected to the connecting slider.

[0008] Preferably, the limiting wheel is connected to a second limiting wheel, the second limiting wheel is provided with a stop wheel, the shape of the stop tooth below corresponds to the stop wheel, the stop wheel is disposed in the guide groove, and spring pieces are fixed on both sides of the connecting slider, the other end of the spring pieces is bent downward.

[0009] Preferably, the limiting wheel has a notch, the limiting wheel has a sliding surface, the sliding surface extends backward from the top of one side of the notch, the end of the bent portion of the spring contacts the sliding surface, the left side of the guide groove is inclined at the position where it connects with the arc surface of the stop tooth, and the top of the guide groove to the right end is inclined.

[0010] Preferably, the memory foam layers of the base and the second base correspond to each other on adjacent sides, and the memory foam layers are made of gel memory foam. Beneficial effects

[0011] After adopting the above technical solution, this utility model has the following advantages compared with the prior art: The ergonomic memory foam cushion of this utility model has an adjustable gap between the base and the second base through a stop box and a connecting slider, which improves compatibility and allows a cushion to be used by people of different body sizes and adapt to different sitting posture scenarios. The stop teeth of the stop wheel and the guide groove prevent the second base from sliding at will, so that people adapt to the product and the product adapts to people, which is more in line with ergonomic design.

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1-4 As shown: An ergonomic memory foam seat cushion includes a base 1 and a second base 2. The base 1 is provided with an upwardly extending backrest 3. The base 1, backrest 3, and second base 2 are provided with memory foam layers 4. The base 1 is provided with a guide box 6. The second base 2 is provided with a connecting slider 5. The guide box 6 and the connecting slider 5 are slidably connected.

[0016] Guide grooves 7 are provided on both sides of the guide box 6. Stop teeth 8 with evenly divided graduations are provided below the guide grooves 7. The left side of the stop teeth 8 is arc-shaped. Limiting wheels 12 are provided on both sides of the connecting slider 5. The limiting wheels 12 are rotatably connected to the connecting slider 5.

[0017] The limiting wheel 12 is connected to the second limiting wheel 13, and the second limiting wheel 13 is provided with a stop wheel 14. The shape of the stop tooth 8 below corresponds to the stop wheel 14. The stop wheel 14 is set in the guide groove 7. The connecting slider 5 is fixed with spring pieces 11 on both sides, and the other end of the spring piece 11 is bent downward.

[0018] The limiting wheel 12 has a notch 9 and a sliding surface 10. The sliding surface 10 extends backward from the top of one side of the notch 9. The end of the bent part of the spring piece 11 contacts the sliding surface 10. The left side of the guide groove 7 is inclined at the position where it connects with the arc surface of the stop tooth 8. The top of the guide groove 7 to the right end is inclined.

[0019] The memory foam layers 4 of the base 1 and the second base 2 are adjacent to each other, and the memory foam layers 4 are made of gel memory foam.

[0020] In use, the second base 2 is pulled to a position matching the user's sitting depth. During this pulling motion, the limiting wheel 12 moves to the left, causing the stopping wheel 14 to slide along the arc surface on the left side of the stopping tooth 8. Simultaneously, the limiting wheel 12 rotates upwards along with the second limiting wheel 13. The downward-bent end of the spring piece 11 slides back and forth on the sliding surface 10. After the stopping wheel 14 reaches the top of the arc surface, it falls into the next stopping tooth 8. To reset the second base 2, it is pulled to the far left. During the process, after the stop wheel 14 disengages from the leftmost stop tooth 8 and moves along the left inclined plane, the limit wheel 12 rotates further upward. The end of the downward-bent portion of the spring piece 11 enters the notch 9, preventing the limit wheel 12 from rotating downward. At this time, the stop wheel 14 is located near the upper position of the guide groove 7. Then, the second base 2 is pushed to the right. When the stop wheel 14 contacts the inclined plane above the guide groove 7, the stop wheel 14 slides along the inclined plane, and the end of the downward-bent portion of the spring piece 11 disengages from the notch 9, causing the limit wheel 12 to rotate downward. The stop wheel 14 returns to the rightmost position of the guide groove 7.

[0021] The above-described embodiments are provided for illustrative purposes. Based on the above description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this utility model is not limited to the contents of the specification; its protection scope must be determined according to the claims.
