Description

Technical Field

[0001] The utility model belongs to the technical field of fabric structures, and more specifically, relates to a heating fabric structure, a seat and a vehicle. Background Art

[0002] Car seats are made of PU foam. PU foam has long faced technical challenges, including resistance to moisture and heat aging, cavitation and cracking caused by unstable foaming processes, and other issues. Current automotive manufacturers adhere a layer of tensile-strength, age-resistant, and bondable non-woven fabric to the PU foam surface. This is typically a multi-layer composite non-woven fabric, with an inner layer of PET long-fiber non-woven fabric and an outer layer of PET staple fiber fabric.

[0003] As people's requirements for car seat comfort continue to increase, many car seats are equipped with electric heating devices based on existing technologies. At present, the electric heating device for seats is to lay electric heating wires on the surface of non-woven fabrics, and use the heat generated by the electric heating wires to heat the seats. However, although non-woven fabrics have good tensile strength and anti-aging capabilities, they have poor ductility. After the user sits on the seat, the entire body weight will be applied to the seat, and the poor ductility of the non-woven fabric makes it unable to deform accordingly with the curves of the human body, and thus cannot fit the curves of the human body. The above phenomenon will cause the contact area between the user and the seat to decrease, resulting in a higher pressure at the contact point between the user and the seat, affecting the comfort of the ride. Utility Model Content

[0004] The purpose of the present utility model is to provide a heating fabric structure, seat and vehicle, aiming to solve the problem in the prior art that the non-woven fabric has poor ductility and the heated seat formed with the heating wire cannot fit the human body, resulting in insufficient comfort for users sitting in the seat.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] In a first aspect, a heating fabric structure is provided, comprising a plurality of fabric layers sequentially distributed in an up-and-down direction and a heating layer disposed between two adjacent fabric layers, wherein the two adjacent fabric layers are connected to each other, and the fabric layers comprise:

[0007] a plurality of deformation zones, sequentially spaced apart along a first direction, the first direction being perpendicular to the up-down direction, the deformation zones having deformation spaces capable of deforming in the up-down direction; and

[0008] The connecting area is provided between two adjacent deformation areas, and is used to connect the two adjacent deformation areas.

[0014] In combination with the first aspect, in a possible implementation, two adjacent fabric layers are spaced apart in the up-down direction, the heating layer is disposed between the two adjacent fabric layers, and the heating layer is respectively connected to the two adjacent fabric layers.

[0015] In combination with the first aspect, in a possible implementation, the longitudinal cross-section of the heating layer is a plurality of triangles distributed sequentially along a first direction, and the vertices of the triangles are connected to the fabric layer.

[0016] The beneficial effect of the heating fabric structure provided by the present invention is that: compared with the prior art, the heating fabric structure of the present invention adopts multiple fabric layers distributed in the vertical direction, which increases the thickness of the heating fabric structure and thus enhances its deformation ability.

After the user sits on the seat, the deformation zone deforms under the action of the user's gravity, thereby fitting the user's body curve, increasing the contact area with the user, reducing the pressure between the user and the heating fabric structure, and improving the user's comfort.

The present invention provides multiple deformation zones distributed at intervals. Compared with the crime of providing a single deformation zone for the fabric layer, the fabric layer can be prevented from deforming and collapsing under the action of its own gravity, ensuring that it has a certain supporting force, and then can produce corresponding deformation according to the user's body curve after the user sits down, thereby improving the comfort during use.

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] In the claims, specification, and drawings of the present invention, unless otherwise expressly defined, terms such as "first," "second," or "third" are used to distinguish between different objects, rather than to describe a specific order. Unless otherwise specified, other directional words such as "vertical," "clockwise," and "counterclockwise" are used to indicate directions or positional relationships based on the directions and positional relationships shown in the drawings, and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or component referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the specific scope of protection of the present invention. In the claims, specification, and drawings of the present invention, unless otherwise expressly defined, terms such as "fixed connection" or "fixed connection" should be understood in a broad sense, that is, any connection method without a displacement relationship or relative rotation relationship between the two, that is, including non-detachable fixed connection, detachable fixed connection, integral connection, and fixed connection through other devices or components. In the claims, specification, and drawings of the present invention, terms such as "including," "having," and their variations are intended to mean "including but not limited to."

[0030] Please also refer to Figures 1 to 3 The heated fabric structure, seat, and vehicle provided by the present invention are now described. The heated fabric structure includes multiple fabric layers 1 sequentially distributed along a vertical direction and a heating layer 2 disposed between two adjacent fabric layers 1. The two adjacent fabric layers 1 are interconnected. The fabric layers 1 include multiple deformation zones 101 and connection zones 102. The multiple deformation zones 101 are sequentially spaced along a first direction, forming a deformation space 1011 in the vertical direction. The connection zone 102 is disposed between two adjacent deformation zones 101 and is used to connect the two adjacent deformation zones 101.

[0031] Compared to the prior art, the heating fabric structure provided by the present invention utilizes multiple fabric layers 1 distributed vertically, increasing the thickness of the heating fabric structure and thereby enhancing its deformability. A heating layer 2 is positioned between two adjacent fabric layers 1. The heat generated by the heating layer 2 is evenly and quickly transferred to the fabric layer 1, allowing the user to feel the temperature change through the fabric layer 1, thus improving the user experience. Furthermore, the deformation zone 101 of the present invention has a deformation space 1011. After the user sits down on the chair, the deformation zone 101 deforms under the user's gravity, conforming to the user's body curves, increasing the contact area with the user, reducing the pressure between the user and the heating fabric structure, and improving user comfort. The provision of multiple, spaced-apart deformation zones 101 in the present invention, compared to a single deformation zone 101 in the fabric layer 1, prevents the fabric layer 1 from deforming and collapsing under its own weight, ensuring a certain degree of support. This allows the fabric layer 1 to deform according to the user's body curves after sitting down, thus improving user comfort.

[0032] It should be noted that the “first direction” refers to any direction in a plane perpendicular to the up-down direction.

[0033] Optionally, the deformation zone 101 and the connection zone 102 are both formed by weaving warp yarns and weft yarns.

[0034] In some embodiments, see Figure 1 The longitudinal section of the deformation zone 101 is a non-closed polygon or ring. The heating fabric structure further includes a connecting layer 3 connecting two adjacent fabric layers 1. The connecting layer 3 includes a plurality of connecting areas 301. The connecting areas 301 are arranged in a one-to-one correspondence with the deformation zones 101. The connecting areas 301 are located at the opening of the deformation zone 101 and close the opening of the deformation zone 101.

[0035] Two vertically adjacent deformation zones 101 are connected by a common connecting zone 301. This means that both ends of the connecting zone 301 simultaneously enclose the two adjacent deformation zones 101 and connect the two adjacent connection layers. Compared to solutions that employ closed polygonal or annular structures for the two deformation zones 101 and then provide a connecting zone 301 to connect the two storage layers, this embodiment simplifies the structure and reduces the weight of the heating fabric structure.

[0036] Optionally, the heating layer 2 includes a plurality of heating zones 201 distributed at intervals. The heating zone 201 is arranged in the deformation zone 101 or between the connection zones 102 of two adjacent fabric layers 1 and is woven and connected to the deformation zone 101 or the connection zone 102 .

[0037] Optionally, the heating zone 201 includes heating wires arranged along the warp and connecting wires arranged along the weft, and the connecting wires are braided and connected to the connecting zone 102 or the deformed edge. The connecting wires can be heating wires or non-heating wires.

[0038] In some embodiments, see Figure 1 The connection areas 102 of two adjacent fabric layers 1 are spaced apart in the up and down directions to form an accommodating space 202 . The heating layer 2 includes a plurality of heating areas 201 . The heating areas 201 are located in the accommodating space 202 and are arranged in a one-to-one correspondence with the accommodating space 202 .

[0039] In this embodiment, the heating area 201 is arranged in the accommodating space 202, which does not affect the deformation amount of the deformation area 101. Moreover, since the connection area 102 is spaced apart in the upper and lower directions, it also has a certain deformation amount, which can improve the overall deformation ability of the heating fabric structure and improve the user's comfort.

[0040] Optionally, the heating zone 201 includes heating wires arranged along the warp and connecting wires arranged along the weft, and the connecting wires are braided and connected to the connecting zone 102 or the deformed edge. The connecting wires can be heating wires or non-heating wires.

[0041] Specifically, the heating area 201 is a planar structure.

[0042] In some embodiments, see Figure 4 , the heights of the multiple deformation zones 101 located in the same fabric layer 1 gradually decrease along the first direction.

[0043] After a person sits on a chair, the buttocks are located on the side of the chair close to the backrest, and the pressure on this side is the greatest, while the pressure on the side away from the backrest gradually decreases. Therefore, when the heating fabric structure of the present application is laid on the chair, the pressure on different parts of the heating fabric structure after the person sits down is also different, that is, the pressure on the side close to the backrest is greater, and the pressure on the side away from the backrest is less. In this embodiment, the heights of the multiple deformation zones 101 of the same fabric layer 1 are designed to decrease in sequence. The side with the highest height of the deformation zone 101 is in contact with the backrest, and the side with the smallest height is located farthest from the backrest. That is, the deformation zone 101 on the side close to the backrest has a larger deformation amount, which can better fit the human body and improve comfort during use.

[0044] It should be noted that "height" refers to the dimension in the up and down direction.

[0045] In some embodiments, see Figure 5 The longitudinal section of the deformation zone 101 is a trapezoidal structure, and the height of the deformation zone 101 gradually decreases along the first direction.

[0046] In this embodiment, the height of the same fabric layer 1 decreases sequentially, resulting in a uniformly decreasing height structure across the entire heating fabric layer 1. During use, the highest side is placed closer to the seat back, and the lowest side is placed farther away from the seat back. This allows the deformation zone 101 contacting the user's buttocks to deform more significantly after seating, while the area contacting the legs experiences less pressure, resulting in a correspondingly smaller deformation. This allows for a more consistent fit with the body's curves, increases the contact area between the user and the heating fabric structure, reduces pressure, and improves comfort during use.

[0047] In some embodiments, see Figure 2 and Figure 3 The longitudinal section of the deformation zone 101 is a closed polygonal or annular structure. The deformation zones 101 of two adjacent fabric layers 1 are connected to each other, and the heating layer 2 is provided between the connection zones 102 of the two adjacent fabric layers 1 .

[0048] In this embodiment, the deformation zones 101 of two adjacent fabric layers 1 are braided and connected, and each deformation zone 101 is a closed polygonal or annular structure. This provides each deformation zone 101 with a certain degree of support, preventing deformation under its own weight and thus preventing the fabric layers 1 from collapsing. The heating layer 2 is positioned between the connection zones 102 of the two adjacent fabric layers 1. This not only does not affect the interconnection of the deformation zones 101, but also avoids the problem of deformation of the deformation zones 101 being affected by stress, which would occur if the heating layer 2 were positioned between corresponding deformation zones 101 above and below.

[0049] Specifically, the heating layer 2 includes a plurality of mutually independent heating zones 201 , and the heating zones 201 correspond to the connection zones 102 one by one.

[0050] In some embodiments, see Figures 2 to 3 The two adjacent fabric layers 1 are spaced apart in the up-down direction, the heating layer 2 is arranged between the two adjacent fabric layers 1 , and the heating layer 2 is respectively connected to the two adjacent fabric layers 1 .

[0051] Two adjacent fabric layers 1 are connected by a heating layer 2. The heating layer 2 is a planar structure and is arranged between the two adjacent fabric layers 1, so that the generated heat can be transferred evenly and quickly to the fabric layer 1 and then to the user through the fabric layer 1.

[0052] In some embodiments, see Figure 3 The longitudinal section of the heating layer 2 is a plurality of triangles distributed in sequence along the first direction, and the vertices of the triangles are connected to the fabric layer 1.

[0053] The longitudinal section of the heating layer 2 is a plurality of triangles. Compared with the planar laying scheme, it not only increases the heating layer 2 and improves the heating efficiency, but also the triangular structure is spaced apart from the adjacent fabric layer 1 to form a spacing space in the upper and lower directions, which can be deformed after being subjected to force, thereby improving the deformation capacity of the heating fabric structure.

[0054] Optionally, the heating layer 2 includes heating wires arranged along the warp direction and connecting wires arranged along the weft direction, which are woven together, and the connecting wires are woven and connected to the fabric layer 1 .

[0055] Based on the same inventive concept, the present invention further provides a seat comprising any one of the above-mentioned heating fabric structures.

[0056] The seat provided by the present invention adopts the above-mentioned heating fabric structure. Multiple fabric layers 1 distributed in the vertical direction increase the thickness of the heating fabric structure, thereby enhancing its deformation ability. A heating layer 2 is provided between two adjacent fabric layers 1. The heat generated by the heating layer 2 can be evenly and quickly transferred to the fabric layer 1, allowing the user to feel the temperature change through the fabric layer 1, thereby improving the user experience. In addition, the deformation zone 101 of the present invention has a deformation space 1011. After the user sits on the seat, the deformation zone 101 deforms under the action of the user's gravity, thereby fitting the user's body curve, increasing the contact area with the user, reducing the pressure between the user and the heating fabric structure, and improving the user's comfort. In the present invention, multiple deformation zones 101 are provided at intervals. Compared with the method of providing a single deformation zone 101 for the fabric layer 1, the deformation and collapse of the fabric layer 1 under its own gravity can be avoided, ensuring that it has a certain support force. After the user sits down, the deformation zone 101 can be correspondingly deformed according to the user's body curve, thereby improving the comfort during use.

[0057] Based on the same inventive concept, the present invention also provides a vehicle comprising the above-mentioned seat.

[0058] The vehicle provided by the present invention adopts the above-mentioned seat. Multiple fabric layers 1 distributed in the vertical direction increase the thickness of the heating fabric structure, thereby enhancing its deformation ability. A heating layer 2 is provided between two adjacent fabric layers 1. The heat generated by the heating layer 2 can be evenly and quickly transferred to the fabric layer 1, allowing the user to feel the temperature change through the fabric layer 1, thereby improving the user experience. In addition, the deformation zone 101 of the present invention has a deformation space 1011. After the user sits on the seat, the deformation zone 101 deforms under the action of the user's gravity, thereby fitting the user's body curve, increasing the contact area with the user, reducing the pressure between the user and the heating fabric structure, and improving the user's comfort. In the present invention, multiple deformation zones 101 are provided at intervals. Compared with the method of providing a single deformation zone 101 in the fabric layer 1, the deformation and collapse of the fabric layer 1 under its own gravity can be avoided, ensuring that it has a certain support force. Then, after the user sits, the deformation zone 101 can be correspondingly deformed according to the user's body curve, thereby improving the comfort during use.

Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
