Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a seat cushion interlayer structure and an automotive seat. Background Technology

[0002] Seat cushions are an important component of car seats, and their structure directly affects the passenger's riding experience.

[0003] Traditional car seat cushions typically consist of a frame, foam, and a cover. The foam itself includes rigid and soft foam layers. The rigid foam layer is located near the frame, providing support, while the soft foam layer is located near the cover, providing comfort and enhancing passenger comfort. However, the foam's rebound response is slow and insensitive, which can negatively impact the passenger experience. Therefore, some manufacturers add springs to the rigid foam layer. Springs offer rapid rebound, effectively improving passenger comfort. However, existing solutions suffer from complex overall structures, cumbersome assembly and disassembly, and low efficiency. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a car seat cushion sandwich structure and car seat that is easy to install and disassemble, efficient and comfortable for passengers.

[0005] The technical solution adopted by this utility model to solve its technical problem is to propose a seat cushion interlayer structure for automobile seats, comprising:

[0006] A bottom support and spring pad module, the spring pad module including a support frame and a plurality of springs, the plurality of springs being constrained by the support frame and padding on the bottom support; wherein, the spring pad module has a first support surface and a second support surface disposed opposite to the first support surface, the first support surface abutting against the bottom support;

[0007] A flexible covering layer covers the second support surface of the spring pad module;

[0008] A face mask, covering the flexible covering layer.

[0009] Furthermore, the spring pad module is configured with a plurality of receiving cavities corresponding one-to-one with the springs, and the springs are housed in the receiving cavities.

[0010] Furthermore, the multiple springs are arranged in multiple rows and columns;

[0011] The support frame surrounds the outer periphery of the multiple rows and columns of springs and is fixed to the outer periphery of the multiple rows and columns of springs.

[0012] Furthermore, the spring pad module is configured with a plurality of receiving bags corresponding one-to-one with the spring, and the receiving cavity is disposed in the receiving bag;

[0013] The multiple containment bags are not interconnected.

[0014] Furthermore, the bottom support is configured as rigid foam;

[0015] The flexible covering layer includes a first soft foam layer and a second soft foam layer. The first soft foam layer covers the second support surface of the spring pad module, and the second soft foam layer covers the first soft foam layer. The cover is wrapped around the second soft foam layer.

[0016] Furthermore, the density of the first soft foam layer is greater than the density of the second soft foam layer, and the thickness of the first soft foam layer is greater than the thickness of the second soft foam layer;

[0017] The first soft foam layer is made of latex.

[0018] Furthermore, the spring pad module is arranged in the shape of a cuboid.

[0019] Furthermore, the containing bag is configured as a flexible bag.

[0020] Furthermore, the car seat is equipped with a frame, and the support frame is fixed to the frame.

[0021] This utility model also proposes a car seat, including a seat cushion, wherein the seat cushion is provided with the above-mentioned seat cushion interlayer structure.

[0022] Compared with the prior art, the present invention has at least the following beneficial effects:

[0023] In this invention, a spring pad module is incorporated into the seat cushion interlayer structure, effectively enhancing seat cushion comfort. Utilizing the elasticity of springs, the cushion provides better support, and the spring's elasticity is more sensitive and rapid than the rebound force of foam. Multiple springs are constrained within the support frame, forming the spring pad module, facilitating overall installation and removal. This eliminates the need to individually install or remove each spring from the car seat, significantly improving efficiency. The bottom support provides rigid support to the spring pad module, allowing the springs to function optimally; the flexible covering layer effectively eliminates the sensation of the springs pressing against the body, further enhancing passenger comfort.

[0024] In this invention, the multiple springs in the spring pad module are arranged in multiple rows and columns to ensure the coverage area of ​​the springs, thereby increasing the support range for passengers and improving comfort. The support frame surrounds and is fixed to the outer periphery of the multiple rows and columns of springs, facilitating the fixation of the spring pad module.

[0025] In this invention, each spring is individually housed in a receiving bag, forming an independent unit. This ensures that no foreign objects will enter the springs during use, thus preventing them from affecting their performance. The receiving bag is flexible, ensuring that the springs are not restricted by the bag's deformation.

[0026] In this invention, the flexible covering layer includes a first soft foam layer and a second soft foam layer. In comparison, the first soft foam layer has a higher density and is thicker. The first soft foam layer is placed on the second support surface of the spring pad module, which can eliminate the foreign body feeling of the spring. The second soft foam layer covers the first soft foam layer and serves as a comfort component, providing passengers with a soft feel and effectively improving comfort. Attached Figure Description

[0041] like Figures 1-4 As shown, the seat cushion interlayer structure of the car seat in this embodiment mainly includes: a bottom support 1, a spring cushion module 2, a flexible covering layer 3, and a cover 4. The flexible covering layer 3 mainly includes a first soft foam layer 31 and a second soft foam layer 32. Specifically,

[0042] The system comprises a bottom support 1 and a spring cushion module 2. The spring cushion module 2 includes a support frame 20 and multiple springs 21. The multiple springs 21 are constrained by the support frame 20 and then cushioned on the bottom support 1. The spring cushion module 2 has a first support surface 201 and a second support surface 202 opposite to the first support surface 201. The first support surface 201 abuts against the bottom support 1. It can be understood that, with the direction of the seat cushion when used on a car seat as a reference, the first support surface 201 is the bottom surface of the spring cushion module 2, and the second support surface 202 is the top surface of the spring cushion module 2. When a passenger sits on the seat cushion, the force applied by the passenger to the spring cushion module 2 is perpendicular to the second support surface 202 and the first support surface 201. The multiple springs 21 are compressed, and the elasticity of the multiple springs 21 provides support for the passenger to improve passenger comfort.

[0043] A flexible covering layer 3 covers the second support surface 202 of the spring pad module 2; the flexible covering layer 3 mainly eliminates the foreign object feeling of the spring 21 and improves passenger comfort.

[0044] The cover 4 covers the flexible covering layer 3. By covering the cover 4, the seat cushion interlayer structure can be covered and fixed to ensure the stability of the structure.

[0045] In this embodiment, a spring pad module 2 is provided in the seat cushion interlayer structure, which can effectively improve the comfort of the seat cushion. Utilizing the elasticity of the spring 21, the seat cushion provides better support, and the elasticity of the spring 21 is more sensitive and rapid than the rebound force of foam. Multiple springs 21 are constrained by the support frame 20, forming the spring pad module 2, facilitating overall installation and disassembly. It eliminates the need to install or remove each spring 21 from the car seat individually, effectively improving installation and removal efficiency. The bottom support 1 provides rigid support for the spring pad module 2, allowing the elasticity of the spring 21 to function better; the flexible covering layer 3 effectively eliminates the foreign body sensation caused by the spring 21, thereby improving passenger comfort.

[0046] The spring pad module 2 is configured with multiple receiving cavities 220 corresponding to each spring 21. The spring 21 is housed in the receiving cavity 220. By housing multiple springs 21 in independent receiving cavities 220, the springs 21 are protected from external interference during operation.

[0047] Specifically, the multiple springs 21 are arranged in multiple rows and columns to ensure that the springs 21 can provide timely support when the passenger is sitting on the seat cushion. The multiple rows and columns of springs 21 can increase the support range and improve the support effect, thereby enhancing the passenger's riding comfort. The multiple rows and columns of springs 21 are arranged to form a cuboid shape, that is, the spring cushion module 2 in this embodiment is arranged in a cuboid shape, which is convenient for arrangement and convenient for setting structures (such as mounting slots or holes) adapted to the cuboid shape.

[0048] The support frame 20 surrounds the outer periphery of the multiple rows and columns of springs 21 and is fixed to the outer periphery of the multiple rows and columns of springs 21.

[0049] It should be explained that the support frame 20 can be configured as a steel wire arranged along the outer periphery of the spring pad module 2 to facilitate the fixation of the entire spring pad module 2.

[0050] The car seat has a frame, and the support frame 20 is fixed to the frame. By fixing the support frame 20 to the car seat frame, the spring pad module 2 is thus fixed to the car seat frame, ensuring structural stability. For example, the support frame 20 can be fixed to the car seat frame using screws.

[0051] In this embodiment, the multiple springs 21 in the spring pad module 2 are arranged in multiple rows and columns to ensure the coverage of the springs 21, thereby increasing the support range for passengers and improving comfort. The support frame 20 surrounds and is fixed to the outer periphery of the multiple rows and columns of springs 21, facilitating the fixation of the spring pad module 2.

[0052] Furthermore, the spring pad module 2 is configured with multiple receiving bags 22 corresponding one-to-one with each spring 21, and the receiving cavity 220 is disposed in the receiving bag 22 to form a bag-shaped spring 21. In addition, the multiple receiving bags 22 are not interconnected, that is, each receiving cavity 220 is independent, and the spring 21 is housed in an independent receiving cavity 220, ensuring that the operation of the spring 21 is not easily disturbed.

[0053] Furthermore, the receiving bag 22 is configured as a flexible bag, that is, the receiving bag 22 is flexible rather than rigid, to ensure that it will not affect the elastic deformation of the spring 21. For example, the receiving bag 22 can be formed by non-woven fabric weaving, and two adjacent receiving bags 22 can be sewn together by stitching to form multiple rows and columns of bag springs 21, ensuring that the multiple rows and columns of springs 21 can work together without interfering with each other during operation.

[0054] In this embodiment, each spring 21 is individually housed within a receiving bag 22, forming an independent unit. This ensures that no foreign objects will enter the spring 21 during use, thus preventing it from affecting its performance. The receiving bag 22 is a flexible bag, ensuring that the spring 21 is not restricted by the bag when it deforms.

[0055] In this embodiment, the bottom support 1 is set as rigid foam to provide support rigidity for the spring 21 in the spring pad module 2, so as to ensure that the elasticity of the spring 21 can be better exerted. For example, the bottom support 1 can be, but is not limited to, a support sponge.

[0056] The flexible covering layer 3 includes a first soft foam layer 31 and a second soft foam layer 32. The first soft foam layer 31 covers the second support surface 202 of the spring pad module 2. The main function of the first soft foam layer 31 is to eliminate the foreign body sensation of the spring 21. Without the first soft foam layer 31, when a passenger sits on the seat cushion, they can clearly feel the spring 21 pressing against their thighs and buttocks, resulting in a noticeable foreign body sensation and affecting the passenger's riding comfort. For example, the first soft foam layer 31 can be, but is not limited to, a cloud-like latex.

[0057] The second soft foam layer 32 covers the first soft foam layer 31. The main function of the second soft foam layer 32 is as a comfort component, configured as a soft and pressure-relieving layer to further enhance the passenger's riding comfort.

[0058] The density of the first soft foam layer 31 is greater than that of the second soft foam layer 32, meaning that the strength provided by the first soft foam layer 31 is slightly greater than that provided by the second soft foam layer 32. Furthermore, the thickness of the first soft foam layer 31 is greater than that of the second soft foam layer 32, and the first soft foam layer 31 is made of latex.

[0059] It needs to be explained that rigid foam and soft foam are relative concepts. Compared to the previous one, the bottom support 1 is set as rigid foam, which can provide greater support strength, that is, rigid foam is relatively harder; while the soft foam layer can provide less support strength, that is, soft foam layer is relatively softer.

[0060] The cover 4 covers the second soft foam layer 32. The cover 4 can cover the second soft foam layer 32 and the first soft foam layer 31 on the spring pad module 2. The spring pad module 2 and the bottom support 1 are fixed on the frame of the car seat to ensure the overall fixation effect of the seat cushion interlayer structure, thereby ensuring the overall structural stability.

[0061] In this embodiment, the flexible covering layer 3 includes a first soft foam layer 31 and a second soft foam layer 32. In comparison, the first soft foam layer has a higher density and is thicker. The first soft foam layer 31 is placed on the second support surface 202 of the spring pad module 2, which can eliminate the foreign body feeling of the spring 21. The second soft foam layer 32 covers the first soft foam layer 31 and serves as a comfort component, providing passengers with a soft feel and effectively improving comfort.

[0062] In this design, the seat cushion interlayer structure is easy to assemble and disassemble, highly efficient, and can improve passenger comfort.
