Description

Technical Field

[0001] This utility model relates to the field of seat cushion technology, specifically a breathable non-woven seat cushion. Background Technology

[0002] A seat cushion is a fabric or filling product used on the surface of a seat. Seat cushions can increase the softness of a seat, reduce the discomfort caused by hard seats, and effectively relieve pressure on the buttocks and reduce fatigue for people who sit in chairs for long periods of time.

[0003] The existing seat cushion design is somewhat unreasonable. Furthermore, due to the lack of a layered moisture-wicking design inside the cushion, sweat accumulates inside the support layer, causing it to become compacted and absorb moisture. This results in poor breathability and overall poor usability of the seat cushion. Utility Model Content

[0004] The purpose of this invention is to provide a breathable non-woven fabric seat cushion that has the advantages of simple structure, reasonable design, rapid moisture wicking, and increased stability of the support layer structure, thus solving the problems mentioned in the above-mentioned technical background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a breathable non-woven fabric seat cushion, which includes a contact layer, a support layer, a bottom layer, and silicone particles; the contact layer is wrapped around the outside of the support layer, the bottom layer is sewn to the bottom of the contact layer, and the silicone particles are pasted to the bottom of the bottom layer, with the silicone particles arranged in a linear array in both the longitudinal and transverse directions.

[0006] The support layer includes PU foam and a TPU mesh wrapped around the PU foam.

[0007] Preferably, the contact layer is a breathable non-woven fabric, and an elastic band is sewn inside the bottom end of the contact layer.

[0008] Preferably, the PU foam has a connecting groove inside, which is egg-shaped, and the TPU mesh has a breathable groove inside, which is diamond-shaped. The breathable grooves inside the flattened TPU mesh are arranged in a linear arrangement both longitudinally and laterally.

[0009] Preferably, a first connecting strip is fixed to one side of the bottom of the TPU mesh, and a second connecting strip is fixed to the bottom of the TPU mesh on the side away from the first connecting strip.

[0010] Preferably, a button is sewn inside the first connecting strip, and the button passes through the inside of the second connecting strip and is attached to the surface of the second connecting strip.

[0011] Preferably, the bottom layer is a TPU-coated nonwoven fabric.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides a breathable non-woven fabric seat cushion, which includes a contact layer, a support layer, a bottom layer, and silicone particles. The contact layer is wrapped around the outside of the support layer, the bottom layer is sewn to the bottom of the contact layer, and the silicone particles are pasted to the bottom of the bottom layer. The silicone particles are arranged in a linear array in both the longitudinal and transverse directions. The overall structure is simple and reasonably designed. Through the TPU mesh and PU foam of the contact layer, a vertical heat dissipation path is formed, and hot and humid air is quickly discharged through capillary effect, avoiding moisture absorption and caking of the support layer, thereby improving the breathability of the seat cushion.

[0014] 2. The egg-shaped connecting groove design of this utility model reduces the weight of the PU foam and improves the airflow efficiency, making the seat cushion more breathable. In addition, the PU foam has high compressive strength, which can extend the service life of the seat cushion.

[0015] 3. By incorporating a bottom layer and silicone particles, this invention improves both the waterproofness and anti-slip properties of the seat cushion, thereby enhancing its practicality. Attached Figure Description

[0025] Please see Figures 1 to 4 One embodiment of this utility model is a breathable non-woven fabric seat cushion, which includes a contact layer 1, a support layer 2, a bottom layer 3 and silicone particles 4; the contact layer 1 is wrapped around the outside of the support layer 2, the bottom layer 3 is sewn to the bottom of the contact layer 1, and the silicone particles 4 are pasted to the bottom of the bottom layer 3, with the silicone particles 4 arranged in a linear array in both the longitudinal and transverse directions.

[0026] The support layer 2 includes PU foam 21 and TPU mesh 23 wrapped around the PU foam 21;

[0027] The contact layer 1 is in direct contact with the surface of the human body and undertakes the core functions of breathability and skin-friendliness. The support layer 2 is used to provide mechanical support and pressure distribution. The bottom layer 3 is a barrier against slipping, wear, and water. The silicone particles 4 are used to enhance the friction between the cushion and the contact surface (such as the seat) to prevent slipping. The PU foam 21 provides the main cushioning support, absorbs the pressure of the human body, and improves the comfort of sitting. The TPU mesh 23 is wrapped around the PU foam to enhance the toughness and wear resistance of the support layer.

[0028] The contact layer 1 is made of breathable non-woven fabric, and an elastic band 11 is sewn inside the bottom end of the contact layer 1;

[0029] The breathable nonwoven fabric has a high porosity fiber structure to ensure air circulation. The elastic band 11 is used to wrap the contact layer 1 around the outside of the support layer 2.

[0030] The PU foam 21 has a connecting groove 22 inside, which is egg-shaped. The TPU mesh 23 has a ventilation groove 24 inside, which is diamond-shaped. The ventilation grooves 24 inside the flattened TPU mesh 23 are arranged in a linear arrangement in both the longitudinal and transverse directions.

[0031] The connecting groove 22 uses a biomimetic oval hole design to reduce the amount of material used while forming an air convection channel and enhancing the support performance of the support layer. The diamond-shaped ventilation groove 24, compared with the round design, can make the TPU mesh 23 have stronger tensile strength.

[0032] A first connecting strip 25 is fixed to one side of the bottom of the TPU mesh 23, and a second connecting strip 26 is fixed to the bottom of the TPU mesh 23 on the side away from the first connecting strip 25.

[0033] A button 27 is sewn inside the first connecting strip 25, and the button 27 passes through the inside of the second connecting strip 26 and is attached to the surface of the second connecting strip 26;

[0034] The first connecting strip 25 and the second connecting strip 26 are used to fix the TPU mesh 23 to the outside of the PU foam 21. The design of the button 27 enables the quick disassembly of the first connecting strip 25 and the second connecting strip 26.

[0035] The bottom layer 3 is made of TPU-coated non-woven fabric.

[0036] TPU-coated nonwoven fabric serves as the bottom protective layer of the seat cushion, preventing wear and tear and isolating external moisture. In addition, TPU-coated nonwoven fabric enhances waterproofness and durability while retaining the breathability of nonwoven fabric.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
