Description

Technical Field

[0001] This utility model relates to the field of memory foam, and in particular to a memory foam with adjustable resilience. Background Technology

[0002] Memory foam, also known as slow rebound foam, is widely used in mattresses, pillows, and chairs to enhance comfort due to its excellent body conformability, pressure distribution, and slow rebound effect. However, the rebound speed and support firmness of traditional memory foam are fixed after production, making it unable to be dynamically adjusted according to different users' weight, sleeping posture preferences, or different usage scenarios, thus lacking flexibility. To overcome this limitation, existing technologies have developed solutions using air bladders to achieve firmness adjustment. By inflating or deflating air into the bladders, the internal air pressure is changed, thereby... Adjusting the overall stiffness of the support structure is an option; however, this type of pure airbag structure has significant drawbacks: First, the support provided by the airbag is significantly insufficient under low pressure, which can easily cause the body to sink excessively and lose effective support; second, after inflation, the airbag forms an unstable "hammock effect," affecting comfort and safety; third, there is a risk of slow air leakage or accidental rupture of the airbag, which would completely lose its support function if it occurred; therefore, there is an urgent need to develop a memory foam with adjustable rebound performance that can flexibly adjust its rebound performance, has high reliability and stable support, and achieves a stable, safe, and comfortable support experience. Utility Model Content

[0003] In order to overcome the limitations of traditional memory foam, where the rebound speed and support hardness are fixed after production and cannot be dynamically adjusted according to different users' weight, sleeping posture preferences, or different usage scenarios, resulting in insufficient flexibility, this invention aims to provide a memory foam with adjustable rebound performance that can flexibly adjust its rebound performance, possesses high reliability and stable support, and achieves a stable, safe, and comfortable support experience.

[0004] This utility model is achieved by the following specific technical means:

[0005] An adjustable-resilience memory foam includes an upper functional layer, an elastic adjustment layer, and a bottom support layer stacked sequentially from top to bottom. The elastic adjustment layer includes a sealed airbag membrane made of a flexible, airtight material and an elastic memory foam core filled within its internal cavity. The airbag membrane is provided with an inflation / deflation port communicating with the external space. Gas is injected into or released into the airbag membrane through this port to change the internal air pressure, thereby adjusting the overall stiffness and resilience of the elastic adjustment layer. The outer surface of the airbag membrane is laminated with a limiting fabric layer to restrict its excessive expansion. The upper functional layer is a multi-layer composite structure including one or more of a breathable layer, a skin-friendly layer, and an antibacterial layer. The bottom support layer is either high-density support cotton or rigid sponge.

[0006] Furthermore, the upper functional layer, the elastic adjustment layer, and the bottom support layer are bonded together with environmentally friendly hot melt adhesive or fixed together by physical means.

[0007] Furthermore, the airbag membrane is made of a flexible and airtight TPU film or rubber film.

[0008] Furthermore, the elastic memory foam core is polyurethane slow rebound memory foam.

[0009] Furthermore, the inflation / deflation interface is a two-way air nozzle or a smart valve that can be connected to a smart air pump.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This invention achieves flexible adjustment of rebound performance, possesses high reliability and stable support, and provides a stable, safe, and comfortable support experience. Attached Figure Description

[0014] The labels in the attached diagram are: 1-upper functional layer, 2-elastic adjustment layer, 3-bottom support layer, 21-airbag membrane, 22-elastic memory foam core, 23-inflation / depression interface, 24-limiting fabric layer. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings: Example

[0016] A type of memory foam with adjustable resilience, such as Figure 1-2 As shown, it includes an upper functional layer 1, an elastic adjustment layer 2, and a bottom support layer 3, which are stacked and composited from top to bottom. The elastic adjustment layer 2 includes a sealed airbag membrane 21 made of flexible airtight material and an elastic memory foam core 22 filled in its internal cavity. The airbag membrane 21 is provided with an inflation / deflation port 23 that communicates with the external space. Gas is injected into or discharged into the airbag membrane 21 through the inflation / deflation port 23 to change the internal air pressure, thereby adjusting the overall stiffness and resilience of the elastic adjustment layer 2. The outer surface of the airbag membrane 21 is composited with a limiting fabric layer 24 to restrict its excessive expansion. The upper functional layer 1 is a multi-layer composite structure including one or more of a breathable layer, a skin-friendly layer, and an antibacterial layer. The bottom support layer 3 is either high-density support cotton or rigid sponge.

[0017] Working principle:

[0018] This invention utilizes the combined effect of an airbag membrane 21 and an elastic memory foam core 22 to achieve efficient control over support performance and rebound characteristics, while overcoming various defects of traditional pure airbags.

[0019] When air is inflated into the airbag membrane 21 through the inflation / deflation port 23, the airbag membrane 21 gradually expands and tends to tighten, increasing its overall rigidity. The elastic memory foam core 22 and the inflated airbag together form a composite cushioning system with higher rigidity, resulting in faster rebound speed and significantly enhanced support. Conversely, when deflated, the airbag membrane 21 relaxes, and the internal elastic memory foam core 22 plays a dominant role, providing a slow rebound and high sink effect that conforms to the body's curves, maintaining comfortable support. Compared with pure airbags, the core advantage is that it eliminates the unstable support that is prone to peripheral bulging and central sinking in traditional pure airbags. The built-in elastic memory foam core 22 provides a continuous and solid base, ensuring that users receive a stable and safe support experience.

[0020] Meanwhile, under low-pressure soft conditions, the conformability of the elastic memory foam core 22 and the buffering effect of air prevent the problem of insufficient support of pure air bladders at low pressure; in the event of slow gas leakage or air bladder rupture, the elastic memory foam core 22 can still provide effective basic support, greatly improving the safety redundancy and reliability of the product; the filling of the elastic memory foam core 22 can also suppress the noise generated by friction and folding of the air bladder membrane 21 during deformation, ensuring a quiet user experience.

[0021] Although this disclosure has been described in detail with reference to exemplary embodiments, it is not limited thereto, and it will be apparent to those skilled in the art that various modifications and changes may be made thereto without departing from the scope of this disclosure.
