[0032] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0033] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0034] The embodiments described in this specification will now be described in detail.

[0035] Reference Figure 1 and Figure 2 As shown, this application discloses a sponge seat cushion, applied to a seating arrangement and installed on top of the seat frame. The sponge seat cushion includes a lower surface 10 and an upper surface 20 disposed opposite each other. The upper surface 20 is for contact with a person's body, and the lower surface 10 contacts the seat frame. The rear side of the sponge seat cushion can rest against the seat back.

[0036] The upper surface 20 includes a main support area 201 and an edge support area 202 located around the main support area 201. The main support area 201 is provided with a recessed portion 30 that is sunken relative to the edge support area 202 and a plurality of protrusions 40 that are raised relative to the recessed portion 30.

[0037] The recess 30 is square and has four sides 301. The recess 30 occupies most of the area of ​​the upper surface 20 and is the main support area. The recess 30 is surrounded by an edge support area 202, which forms a closed area, including four elongated areas corresponding to the four sides of the upper surface 20.

[0038] The four sides 301 of the recessed portion 30 are all inclined, and the sides 301 form an obtuse angle with the bottom surface 303 of the recessed portion 30. The connection between the recessed portion 30 and the edge support area 202 is provided with a rounded chamfer.

[0039] Please refer to Figure 3 As shown, according to another embodiment of this application, each of the four sides 301 is provided with a plurality of spaced transition recesses 302, and each transition recess 302 has a transition surface 3021 that is inclined inward relative to the edge support area 202.

[0040] The tilted design of the side surface 301 and the transition surface 3021 avoids the difference in seating comfort between the edge support area 202 and the main support area 201, avoids the pressure of hard edges, and brings a softer support experience.

[0041] According to other embodiments of this application, the recess 30 may also be circular, polygonal, or other shapes.

[0042] The protrusion 41 is a raised point provided in the recess 30. Figure 1 The shape of the central protrusion is a frustum. The protrusion 41 has a draft transition surface 411, the radial dimension of the protrusion 41 gradually decreases from bottom to top, and the protrusion 41 and the recess 30 are connected by an arc transition.

[0043] The protrusions 41 are independently arranged in a matrix in the main support area 201 and symmetrically arranged along the left and right directions of the sponge cushion. The protrusions 41 are identical in shape and are spaced at equal intervals along the front-to-back and left-to-right directions of the sponge cushion. The top of the protrusions 41 is higher than the edge support area 202, and the multiple protrusions 41 together with the upper end of the edge support area 202 form a support surface that protrudes upward in the middle.

[0044] According to an embodiment of this application, the recessed portion 30 is only provided on the upper part of the sponge cushion, and its lower part is a solid sponge with a certain thickness. The height of the protrusion 41 is 10mm-30mm, and the depth of the recessed portion 30 accounts for 15%-40% of the thickness of the sponge cushion.

[0045] In another embodiment, the tops of the plurality of protrusions are flush with the edge support area 202, and the plurality of protrusions and the upper ends of the edge support area 202 are in the same plane.

[0046] In another embodiment, the tops of the plurality of protrusions are lower than the edge support area 202, and the plurality of protrusions together with the upper end of the edge support area 202 form a support surface that is concave in the middle.

[0047] Multiple protrusions 41 are integrally molded on the sponge cushion, increasing the structural stability of the sponge cushion.

[0048] In another embodiment, the sponge cushion and the protrusion 41 can also be molded separately, and then the protrusion 41 is attached to the bottom surface 303 of the recess 30.

[0049] The spacing between the protrusions 41 helps improve the breathability and ventilation of the foam cushion, preventing heat buildup from prolonged sitting and keeping the cushion dry and comfortable. The rounded corners and smooth transitions allow it to conform more naturally to the curves of the human body, reducing direct pressure and providing a smoother, more comfortable feel.

[0050] Please refer to Figure 4 As shown, it is similar to Figure 1 The only difference in the embodiment is the shape of the protrusion 42. The protrusion 42 has a draft transition surface 421.

[0051] According to other embodiments of this application, the protrusion may also be a square boss, a spherical shape, or a serrated shape. The above shapes can be used alone on a sponge cushion or in combination on a sponge cushion.

[0052] In another embodiment (not shown), the recessed portion includes multiple small indentations, which are independently arranged and matrix-like in the main support area. The small indentations are integrally formed on the sponge cushion, and are recessed portions relative to the upper surface of the sponge cushion. The protrusions are located between the multiple small indentations, on the original upper surface of the sponge cushion.

[0053] When the upper surface of the foam cushion is a flat surface, and the top of the protrusions is flush with the edge support area, multiple protrusions and the upper ends of the edge support area are in the same plane. When the upper surface of the foam cushion is a curved surface, and the top of the protrusions is higher or lower than the edge support area, multiple protrusions and the edge support area together form a support curved surface.

[0054] The material of the foam cushion is molded foam, which is a soft and porous material that increases the breathability of the foam cushion. At the same time, molded foam is more malleable and can be processed by cutting, pressing, folding and other methods according to actual needs. Main support area 201 and multiple protrusions 42.

[0055] This application utilizes a textured structure formed by alternating recessed portions 30 and raised portions 42. This textured feature on the upper surface 20 of the foam seat cushion ensures comfort for short-term use, accelerates airflow to aid in heat dissipation during longer sitting periods, and enhances overall seating comfort.

[0056] This application also discloses a seating fixture, including a sponge cushion placed on a seat frame.

[0057] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
