Description

Technical Field

[0001] This utility model relates to the field of automotive foam seat cushion technology, and in particular to an automotive foam seat cushion with good breathability. Background Technology

[0002] Some car seat cushions on the market use a single piece of polyurethane foam, or sponge, which is widely used due to its excellent plasticity, high resilience and cost control. The outside of this foam filling block is usually covered with a layer of fabric or artificial leather.

[0003] In existing technologies, traditional foam seat cushions, due to the lack of specific ventilation mechanisms, tend to accumulate heat as driving time increases. Furthermore, the heat generated by the contact surface between the human body and the seat cushion cannot dissipate into the interior and below the cushion in a timely manner, resulting in a large amount of heat accumulating at the contact interface, especially in the main areas of the buttocks and groin. This heat causes the occupant's buttocks to accumulate heat and sweat, thus requiring a solution. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a car foam seat cushion with good breathability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A breathable car seat cushion includes a supporting sponge layer, on the upper part of which a seat cushion sponge layer and a surface sponge are sequentially connected. A foam tube is installed inside the supporting sponge layer. An arched chamber is provided on one side of the foam tube and is connected to the outside through an air inlet. Duckbill valve mechanisms for air intake and exhaust are provided on both sides of the arched chamber. The arched chamber and the foam tube are filled with high-resilience sponge. A pair of latex support tubes are installed in the middle of the seat cushion sponge layer, and the latex support tubes extend downward and are connected to the foam tubes.

[0006] In addition, a preferred structure is that the interior of the supporting sponge layer has a groove for installing a foam tube, both ends of the foam tube are open and connected to the outside, and one side of the foam tube is connected to an arched chamber, and one side of the arched chamber is connected to an air inlet.

[0007] Furthermore, in a preferred configuration, the latex support tube is arranged in the buttock support area of ​​the seat cushion sponge layer, and the interior of the latex support tube has a cross-mesh structure.

[0008] In addition, a preferred structure is that both the supporting sponge layer and the seat cushion sponge layer have multiple vertically penetrating ventilation holes on one side.

[0009] In addition, in a preferred configuration, the connection between the arched chamber and the foam tube is designated as the air outlet, and the connection between the arched chamber and the air inlet is designated as the air inlet. Both the air outlet and the air inlet are equipped with duckbill valve mechanisms to achieve unidirectional air intake and exhaust functions.

[0010] Furthermore, a preferred structure is that the duckbill valve mechanism includes a mounting base and a pair of rubber diaphragms arranged symmetrically in a V-shape, which naturally close to form a seal in their natural state.

[0011] The beneficial effects of this utility model are as follows: In this invention, components such as arched chambers, high-resilience sponge, and foam tubes inside the supporting sponge layer actively guide airflow and work in conjunction with a pair of latex support tubes in the seat cushion sponge layer to achieve a complete airflow channel, thereby improving the overall breathability of the seat cushion and effectively reducing the heat generated by the contact surface between the human body and the seat cushion.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-4 A breathable car seat cushion includes a supporting sponge layer 1, a seat cushion sponge layer 2 and a surface sponge 4 connected sequentially to the upper part of the supporting sponge layer 1, and a foam tube 3 installed inside the supporting sponge layer 1. The foam tube 3 has an arched chamber 10 on one side, which is connected to the outside through an air inlet 8. The arched chamber 10 has duckbill valve mechanisms 9 on both sides for air intake and exhaust. The arched chamber 10 and the foam tube 3 are filled with high-resilience sponge 7. The high-resilience sponge 7 has a high porosity and can guide the air in the arched chamber 10 to be squeezed out when it is under pressure. After the pressure is released, it quickly rebounds and draws in air.

[0016] A pair of latex support tubes 5 are installed in the middle of the seat cushion foam layer 2. The latex support tubes 5 extend downward and connect with the foam tubes 3. The latex support tubes 5 are arranged in the buttock support area of ​​the seat cushion foam layer 2. The inside of the latex support tubes 5 is a cross-mesh structure with large gaps and high breathability. Together with the seat cushion foam layer 2, they can effectively support the passenger's buttocks and improve air circulation in this area.

[0017] The interior of the supporting sponge layer 1 has a groove for installing the foam tube 3. Both ends of the foam tube 3 are open and connected to the outside. One side of the foam tube 3 is connected to the arched chamber 10, and one side of the arched chamber 10 is connected to the air inlet 8. Both the supporting sponge layer 1 and the seat cushion sponge layer 2 have multiple vertically open ventilation holes 6 on one side.

[0018] The arched cabin 10 is made of flexible rubber.

[0019] The connection between the arched chamber 10 and the foam tube 3 is set as the air outlet, and the connection between the arched chamber 10 and the air inlet 8 is set as the air inlet. Both the air outlet and the air inlet are equipped with duckbill valve mechanisms 9 to realize one-way air intake and exhaust functions. The duckbill valve mechanism 9 includes a mounting base and a pair of rubber diaphragms arranged symmetrically in a V-shape. In its natural state, the two rubber diaphragms close naturally to form a seal. Among them, the duckbill valve mechanism 9 located at the air outlet has its rubber diaphragm facing the foam tube 3 to achieve a single air outlet operation, and correspondingly, the duckbill valve mechanism 9 located at the air inlet has its rubber diaphragm facing the arched chamber 10 to achieve a single air inlet operation.

[0020] In this embodiment, a latex support tube 5 is provided in the buttock support area of ​​the seat cushion foam layer 2. Its large-diameter structure helps to improve the air circulation efficiency in this area. During actual driving, the seat cushion foam layer 2 will exert pressure on the top of the arched cabin 10 located on one side due to vehicle bumps or the movement caused by the adjustment of the passenger's posture.

[0021] Because the top of the arched chamber 10 is significantly higher than the supporting sponge layer 1, it preferentially bears a larger load and deforms. This deformation will cause the high-resilience sponge 7 inside to be compressed, thereby expelling the air in the cavity to the foam tube 3 in one direction through the duckbill valve mechanism 9. This repeatedly generates a weak airflow, gradually promoting the air circulation and exchange inside the seat cushion system. Compared with traditional sponge seat cushions, this mechanism can effectively improve the breathability of the seat cushion and solve the problem of heat accumulation in the occupant's buttock area.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
