Description

Technical Field

[0001] This utility model relates to the field of seating, specifically to a sponge core for seating. Background Technology

[0002] Seats typically consist of a frame, a foam core, and a lining fabric on the surface. When a user sits down, the foam core is compressed, making the foam compact and reducing its breathability. This, in turn, reduces the overall breathability of the seat. If perforations are made in the foam core to improve breathability, its strength decreases, making it more prone to horizontal deformation. When people sit on the cushion, it tends to tilt laterally, affecting comfort. In this case, the perforations may also become blocked due to deformation, further impacting the breathability of the foam core. Utility Model Content

[0003] The purpose of this invention is to provide a sponge core for seats to overcome the above-mentioned defects in the prior art.

[0004] According to this utility model, a sponge core for a seat includes a sponge body with multiple vertically penetrating vent holes. The upper opening of each vent hole is recessed radially outward to form an installation groove. A support tube is disposed within each vent hole. A ventilated cover is disposed within the installation groove to cover the vent holes. A support ring is disposed on the lower side of the ventilated cover and fixed to its lower edge. The support ring abuts against the bottom wall of the installation groove. A connecting ring is fixed to the lower end face of the support ring and embedded in the upper end of the vent hole. The upper end of the support tube is connected to the connecting ring. The support tube can elastically deform along its axial direction. Multiple vertically penetrating vent holes are disposed within the ventilated cover.

[0005] Preferably, the peripheral wall of the support tube is wavy, and the support tube is made of rubber.

[0006] Preferably, the upper end of the support tube is fixedly provided with a connecting part embedded in the connecting ring, and a supporting part that abuts against the lower end of the connecting ring is fixed around the outer periphery of the connecting part.

[0007] Preferably, a limiting ring is fixed at the lower end of the support tube to abut against the lower end surface of the sponge body, and the support tube, support part, connecting part and limiting ring are integrally formed of rubber.

[0008] Preferably, a support plate is fixed to the lower end face of the sponge body, and a plurality of through holes are opened in the support plate along its thickness and corresponding to the ventilation holes, and the limiting ring is located in the through holes.

[0009] Preferably, the lower end face of the support plate is fixed with a square-shaped support leg, and a through groove is provided on the side wall of the support leg.

[0010] The beneficial effects of this utility model are as follows: by opening the ventilation holes and mounting grooves in the sponge body, the air permeability of the sponge body is increased. At the same time, the strength of the sponge body is increased by the support tube. The elastic deformation of the support tube ensures the elasticity of the sponge body. When the sponge body is compressed, the support tube can provide support in the radial direction of the ventilation holes, thereby ensuring the air permeability of the ventilation holes and reducing the lateral deformation of the sponge when compressed. The support feet support the support plate, and the opening of the grooves allows the support tube to communicate with the outside, thereby ensuring the air permeability of the support tube.

[0017] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

The specific features of a sponge core for a seat are described in detail below:

[0018] One embodiment of this utility model:

[0019] Reference Figures 1-3 This utility model provides a sponge core for seats, including a sponge body 10. The sponge body 10 has multiple vertically penetrating ventilation holes 12. The upper opening of the ventilation holes 12 is recessed radially outward to form an installation groove 11. A support tube 30 is provided in the ventilation holes 12. A ventilation cover 20 covering the ventilation holes 12 is provided in the installation groove 11. A support ring 21 is fixed to the lower edge of the ventilation cover 20. The support ring 21 abuts against the bottom wall of the installation groove 11. A connecting ring 23 embedded in the upper end of the ventilation hole 12 is fixed to the lower end of the support ring 21. The upper end of the support tube 30 is connected to the connecting ring 23. The support tube 30 can undergo elastic deformation along its axial direction. Multiple vertically penetrating ventilation holes 22 are provided in the ventilation cover 20.

[0020] The support tube 30 has a wavy circumference and is made of rubber, which gives it good elasticity in the axial direction.

[0021] The upper end of the support tube 30 is fixed with a connecting part 33 embedded in the connecting ring 23. A supporting part 31 is fixed around the outer periphery of the connecting part 33 and abuts against the lower end of the connecting ring 23. The setting of the supporting part 31 allows the support tube 30 to be compressed downward when the vent hood 20 is pressed down.

[0022] A limiting ring 34 is fixed at the lower end of the support tube 30, which abuts against the lower end surface of the sponge body 10. The support tube 30, the support part 31, the connecting part 33 and the limiting ring 34 are integrally formed of rubber. The setting of the limiting ring 34 ensures that when the support tube 30 is compressed and rebounds, the lower end of the limiting ring 34 can remain flush with the lower end surface of the sponge body 10.

[0023] A support plate 40 is fixed to the lower end face of the sponge body 10. Multiple through holes 43 are opened in the support plate 40, which are through its thickness and correspond to the ventilation holes 12. The limiting ring 34 is located in the through holes 43. A square-shaped support foot 42 is fixed to the lower end face of the support plate 40. A through groove 41 is opened on the side wall of the support foot 42, which supports the sponge body 10 upward. The opening of the through groove 41 allows the support tube 30 to communicate with the outside, thereby ensuring the ventilation function of the support tube 30.

[0024] In use, the sponge body 10 is cut into the shape required for the seat. Multiple mounting grooves 11 and ventilation holes 12 are cut into the sponge body 10 using a laser cutting machine. Support tubes 30 of different heights are selected according to the shape of the sponge body 10, and the support tubes 30 are installed in the ventilation holes 12. The ventilation cover 20 is fixed in the mounting groove 11. The sponge body 10 is fixed on the support plate 40. Then, the present invention is fixed on the seat frame, the support leg 42 is fixed on the seat frame, and the lining cloth is covered on the sponge body 10 and fixed to the seat frame.

[0025] When the seat is compressed, the support tube 30 is compressed in the axial direction. The elasticity of the support tube 30 increases the elasticity of the sponge body 10. At the same time, the support tube 30 supports the ventilation hole 12 in the radial direction, thereby ensuring the breathability of the ventilation hole 12. This ensures that the seat can still maintain good breathability when the user is sitting on it.

[0026] Those skilled in the art will appreciate that various modifications to the above embodiments can be made without departing from the overall spirit and concept of this utility model. All such modifications fall within the protection scope of this utility model. The protection scheme of this utility model is defined by the appended claims.
