AI Technical Summary
The seat area of a block sofa lacks an overall rigid frame, causing concentrated stress and making it prone to collapse. Conventional sofa cushions cannot effectively distribute the pressure, affecting its lifespan.
A flat, elastic band is placed under the seat cushion and fixed to Velcro with a flat connecting strap to form an elastic support structure. This structure is then placed on the sofa to distribute the body weight and reduce the stress and deformation of the filling material.
It effectively distributes pressure on the human body, reduces localized deformation of the filling material in the blocky sofa, extends its service life, and improves comfort.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of sofa cushion technology, specifically to a sofa cushion suitable for block sofas. Background Technology
[0002] Tofu block sofas generally do not provide as much support as traditional sofas, mainly because their modular design lacks an overall rigid frame. The seat area is prone to concentrated stress and collapse. On the other hand, regular sofa cushions are just home furnishings placed on the sofa seat, mainly used to increase comfort, protect the sofa, and decorate for aesthetic purposes, but they cannot effectively distribute the stress on the seat area. Utility Model Content
[0003] To address the aforementioned technical shortcomings, this invention provides a sofa cushion suitable for block sofas, which can effectively distribute the force on the seat area of the block sofa, reduce its deformation, and extend its service life.
[0004] This utility model discloses a sofa cushion suitable for block sofas, including a seat cushion, a flat elastic band, a flat connecting band, and Velcro. A flat elastic band is provided under the seat cushion, with one end of the flat elastic band connecting upward to the left side of the seat cushion and the other end connecting upward to the right side of the seat cushion. Flat connecting bands are provided on the left and right sides of the seat cushion at positions corresponding to the flat elastic bands. One end of the flat connecting band is connected to the seat cushion, and the inner side of the other end of the flat connecting band is connected to the outer side of the flat elastic band by Velcro.
[0005] The principle of the above technical solution is as follows: by setting a flat elastic band around the bottom of the seat cushion, the flat elastic band and the seat cushion are put on the tofu block sofa when in use, so that the seat cushion is located at the seat of the tofu block sofa. The flat elastic band is stretched, and then the flat connecting band is fixed to the flat elastic bands on both sides of the seat cushion with Velcro, so that the seat cushion is taut. When sitting on the seat cushion, it can effectively distribute the weight of the human body, thereby reducing the stress deformation of the filling material of the tofu block sofa and extending the service life of the tofu block sofa.
[0006] Furthermore, the hook and loop fastener includes a hook side and a loop side. The loop side of the hook and loop fastener is located on the outside of the flat elastic band, while the hook side is located on the inside of the flat connecting band. The hook side is relatively rough and may scratch the skin or clothing if it is directly exposed, so it is hidden inside the connecting band. The exposed loop side is softer and improves the comfort of use.
[0007] Furthermore, the length of the loop side of the hook and loop fastener is greater than the length of the hook side. Because the loop side is longer, the hook side can be adjusted and fixed in a wider range, enhancing the flexibility of adjustment.
[0008] The sofa cushion obtained by this utility model is suitable for block sofas. Its beneficial effects are that by wrapping the bottom of the cushion with a flat elastic band and fixing it with Velcro on both sides, an elastic support structure is formed. After being put on the block sofa, the rebound force generated by the stretching of the flat elastic band, together with the flat connecting band, can effectively disperse the pressure of the human body, significantly reduce the local stress deformation of the filling material of the block sofa, and extend its service life.

[0012] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0013] Example 1:
[0014] like Figure 1 , 2 As shown in Figure 3, this utility model discloses a sofa cushion suitable for a block sofa, including a seat cushion 1, a flat elastic band 3, a flat connecting band 2, and Velcro. The flat elastic band 3 is provided under the seat cushion 1. One end of the flat elastic band 3 is connected upward to the left side of the seat cushion 1, and the other end of the flat elastic band 3 is connected upward to the right side of the seat cushion 1. The flat connecting band 2 is provided on the left and right sides of the seat cushion 1 at the positions corresponding to the flat elastic band 3. One end of the flat connecting band 2 is connected to the seat cushion 1, and the inner side of the other end of the flat connecting band 2 is connected to the outer side of the flat elastic band 3 by Velcro. The Velcro includes a hook side 5 and a pile side 4. The pile side 4 of the Velcro is provided on the outer side of the flat elastic band 3, and the hook side 5 of the Velcro is provided on the inner side of the flat connecting band 2. The length of the pile side 4 of the Velcro is greater than the length of the hook side 5 of the Velcro.
[0015] The principle of the above technical solution is as follows: by setting a flat elastic band 3 around the bottom of the cushion 1, when in use, the flat elastic band 3 and the cushion 1 are put on the tofu block sofa, so that the cushion 1 is on the upper side of the tofu block sofa. The flat elastic band 3 is stretched, and then the flat connecting band 2 is fixed to the flat elastic bands 3 on both sides of the cushion 1 with Velcro, so that the cushion 1 is taut. When sitting on the cushion 1, the weight of the human body can be effectively distributed, thereby reducing the stress deformation of the filling material of the tofu block sofa and extending the service life of the tofu block sofa.
