[0016] The following further details the specific embodiments of the present utility model. It should be understood that the description of the embodiments of the present utility model herein does not limit the protection scope of the present utility model.

[0017] Please refer to Figures 1 to 3 , which is a schematic structural diagram of a sofa cushion with high fullness and high stiffness provided by the present utility model. The sofa cushion with high fullness and high stiffness includes a sofa frame 10, a plurality of elastic strips 20 arranged in the sofa frame 10, at least two sponge cushions 30 arranged above the elastic strips 20, and a cushion 40 arranged above the sponge cushions 30. It can be imagined that the sofa cushion with high fullness and high stiffness also includes some other functional modules, such as sofa covers, etc., which are well-known technologies to those skilled in the art and will not be elaborated here.

[0018] The sofa frame 10 includes a contour frame 11, a plurality of mounting brackets 12 arranged on the contour frame 11, and a plurality of support brackets 13 connected to the contour frame 11.

[0019] The sofa frame 10 is used to support and maintain the shape of the sofa cushion. In this embodiment, the contour frame 11 is in an irregular oval shape. The two sides of the contour frame 11 are straight, and the sides in contact with the thighs and the opposite sides in contact with the thighs are arc-shaped, which are used to adapt to the human body's needs. The arc-shaped design reduces the edge pressure of the sofa cushion to improve comfort.

[0020] A plurality of the mounting brackets 12 are arranged in parallel. In the direction close to the sponge cushion 30, the mounting brackets 12 are flush with the contour frame 11 to provide support for the sponge cushion 30. The mounting brackets 12 are used to mount the elastic strips 20 and assist the elastic strips 20 in supporting the sponge cushion 30. In this embodiment, the mounting brackets 12 are arranged at both ends of the arc of the contour frame 11 to increase the installation range of the elastic strips 20. The mounting brackets 12 are provided with mounting holes for mounting the elastic strips 20.

[0021] A plurality of the support brackets 13 are arranged on the contour frame 11 to support the contour frame 11 and maintain the stability of the sofa cushion. One end of the support bracket 13 supports on the ground, and the other end of the support bracket 13 is connected to the contour frame 11 and is provided with a slope near the contour frame 11 to provide enhanced support strength.

[0022] A plurality of the elastic strips 20 are mounted on the mounting brackets 12. The elastic strips 20 include at least two connectors 21 respectively arranged on two of the mounting brackets 12, at least one elastic band 22 connecting the two connectors 21, and at least one elastic plastic strip 23 arranged in the elastic band 22.

[0023] The connecting member 21 is arranged on the facing end faces of the two mounting brackets 12. The connecting member 21 is fixed in the mounting holes on the mounting bracket 12 through fasteners.

[0024] The elastic band 22 uses an elastic material to increase its resilience, so as to assist the sponge cushion layer 30 to improve the stiffness of the sofa cushion. The elastic band 22 is arranged on the connecting member 21 in an unstretched state. Both ends of the elastic band 22 are respectively arranged on the connecting members 21 of the two mounting brackets 12.

[0025] The elastic plastic strip 23 is pressed on the elastic band 22, and both ends thereof are connected to the connecting member 21. The elastic plastic strip 23 uses a high-strength elastic material to support the sponge cushion layer 30 and the cushion 40, provide support for the elastic strip 20, reduce the loss suffered by the elastic band 22, and is beneficial to increasing the service life of the elastic strip 20. The elastic plastic strip 23 is buffered by the support of the elastic band 22 to reduce the loss suffered by the elastic plastic strip 23. The elastic plastic strip 23 provides elastic support for the sponge cushion layer 30, so that the sponge cushion layer 30 takes the plane where the elastic strip 20 is located as the bottom surface, which is beneficial to improving the plumpness and stiffness of the sofa cushion.

[0026] The sponge cushion layer 30 is arranged between the elastic strip 20 and the cushion 40. In the direction from the cushion 40 to the elastic strip 20, the areas of multiple layers of the sponge cushion layer 30 are arranged from large to small. The sponge cushion layers 30 are stacked within the area range of the elastic strip 20, and the installation positions are confirmed by the elastic strip 20. The same-direction side surfaces of multiple sponge cushion layers 30 are respectively attached to the same side of the connecting member 21, and the side edges perpendicular to the attached connecting member 21 are respectively clamped by the elastic plastic strip 23. The sponge cushion layer 30 is squeezed by the cushion 40 and supported by the elastic strip 20. The sponge cushion layers 30 on the side attached to the connecting member 21 support each other, and the small-area sponge cushion layers 30 on the opposite side cannot support the large-area sponge cushion layers 30, so that the sponge cushion layer 30 takes the elastic strip 20 as the bottom surface to form an arc-shaped structure to support the cushion 40, thereby making the cushion 40 form an arc under the influence of the shape of the sponge cushion layer 30 to improve the stiffness and plumpness of the sofa cushion. Since different supporting forces are provided at the multi-layer sponge cushion layer 30 and the single-layer sponge cushion layer 30 respectively, different supporting forces are provided for the user at the center and the edge of the cushion 40, improving the user's comfort.

[0027] The cushion 40 is arranged in a block shape above the sofa cushion layer 30. The cushion 40 is used to provide a good sitting feeling, and the cushion 40 is a general technology and will not be elaborated here.

[0028] Compared with the prior art, a sofa cushion with high fullness and high stiffness provided by the utility model increases the fullness and stiffness of the sofa cushion with high fullness and high stiffness by arranging the elastic band 22 and the sponge cushion layer 30. The elastic band 22 and the elastic plastic strip 23 in the elastic strip 20 and the sponge cushion layer 30 use elastic materials to improve the stiffness of the sofa cushion with high fullness and high stiffness. The elastic plastic strip 23 supports the sponge cushion layer 30 and the cushion 40, reducing the supporting force on the elastic band, which is beneficial to reducing the loss of the elastic band 22, thereby increasing the stiffness of the elastic band 22. In the direction from the cushion 40 to the contour frame 11, the area of the sponge cushion layer 30 is set from large to small, so that the sponge cushion layer 30 forms an arc-shaped structure with the elastic strip 20 as the bottom surface to support the cushion 40, thereby improving the fullness of the sofa cushion with high fullness and high stiffness.

[0029] The above are only the preferred embodiments of the utility model and are not used to limit the protection scope of the utility model. Any modifications, equivalent replacements or improvements within the spirit of the utility model are covered within the scope of the claims of the utility model.
