Technical Field

[0002] The present application relates to the field of vehicle technology, and in particular to seats and vehicles. Background Art

[0003] Vehicle seats are the only part that comes into direct contact with the human body throughout the entire vehicle's ride. With the development of the automotive industry and increasing vehicle usage, users' expectations for the driving experience are constantly improving. Therefore, improving seat comfort is a technical challenge facing those skilled in the art.

[0004] Summary of the Invention

[0005] The present application provides a seat and a vehicle that can improve the driving experience.

[0006] In a first aspect, the present application provides a seat, characterized in that the seat comprises a cover layer, a foam layer and a skeleton support layer; the foam layer is located between the cover layer and the skeleton support layer;

[0007] The aforementioned cover layer includes a first layer and a second layer, wherein the aforementioned first layer includes leather material, polyurethane material, polyvinyl chloride material or a weavable material, and the aforementioned second layer is a first sponge;

[0008] The foaming layer includes a third layer and a fourth layer, wherein the third layer includes a second sponge and the fourth layer includes foam.

[0009] Optionally, the above-mentioned weavable material is, for example, cotton, linen, plant fiber, artificial fiber or wool, etc.

[0010] Optionally, the foam in the fourth layer is foamed resin or polyethylene foam, etc.

[0011] In the above solution, the cover layer comprises a first layer of soft fabric, on which a soft sponge (the aforementioned first sponge) is laminated. Furthermore, a second soft sponge is arranged in a foam layer beneath the cover layer, thereby achieving a soft seat surface. Furthermore, foam, such as a foamed resin or polyethylene foam, is arranged beneath the second sponge to provide good support and thus enhance seat comfort.

[0012] In a possible implementation, the third layer is closer to the cover layer than the fourth layer, and the foaming hardness of the second sponge is smaller than the foaming hardness of the foam.

[0013] In the above solution, the cover layer is the layer that comes into contact with the user. The third layer is closer to the cover layer than the fourth layer. The second sponge in the third layer is designed to have a lower hardness, resulting in greater softness and providing a softer seat surface feel. Furthermore, the foam in the fourth layer is designed to have a higher hardness, providing better support. This supportive foam beneath the second sponge provides even greater support.

[0014] In a possible implementation, the foaming hardness of the first sponge is smaller than the foaming hardness of the second sponge.

[0015] In the above solution, the second layer is closer to the user, so the first sponge of the second layer is softer than the second sponge of the third layer, which can provide the user with a better riding experience.

[0016] In a possible implementation, the foaming layer further includes a fifth layer, wherein the fifth layer includes a three-dimensional plastic braid.

[0017] Optionally, the fifth layer is located between the third layer and the fourth layer.

[0018] In the above solution, the foaming layer includes a three-dimensional plastic braid, which can play a strong supporting role on the one hand and also play a ventilation role on the other hand.

[0019] In a possible implementation, the aforementioned cover layer or the aforementioned foam layer further includes a sixth layer, wherein the aforementioned sixth layer includes a heating pad.

[0020] In the above solution, adding a heating pad to the seat can provide heating service for users and improve user experience.

[0021] In a possible implementation, the foaming layer further includes a seventh layer, and the seventh layer includes massage air bags.

[0022] In the above solution, adding massage air bags to the seats can provide massage services to users and improve user experience.

[0023] In one possible implementation, the seat includes a backrest, and the backrest includes the surface cover layer, the foam layer and the skeleton support layer; the skeleton support layer of the backrest includes an eighth layer and / or a ninth layer, wherein the eighth layer includes a lumbar support and the ninth layer includes a backrest spring.

[0024] In the above solution, adding a lumbar support and / or backrest spring to the backrest can provide strong support for the user and improve the user experience.

[0025] In one possible implementation, the seat includes a seat cushion, which includes the surface cover layer, the foam layer, and the skeleton support layer; the skeleton support layer of the seat cushion includes a suspension spring.

[0026] In the above solution, adding suspension springs to the seat cushion can provide strong support for users and improve user experience.

[0027] In a possible implementation, the foam in the fourth layer is arranged in the wing area of ​​the seat, and the second sponge in the third layer is arranged in the middle block area surrounded by the wing area.

[0028] In this solution, a soft secondary sponge is placed in the body contact area (between the backrest and seat cushion), ensuring a soft feel in these areas. The supporting wing areas are constructed with a harder foam to achieve excellent seat wrapping, ensuring that the outer thighs and sides of the body are well covered during cornering, providing excellent lateral support.

[0029] In a second aspect, the present application provides a vehicle comprising a seat as described in any one of the first aspects above. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In the embodiment of the present application, "multiple" refers to two or more. In the embodiment of the present application, "and / or" is used to describe the association relationship of associated objects, indicating three relationships that can exist independently. For example, A and / or B can be expressed as follows: A exists alone, B exists alone, or A and B exist at the same time. The description methods such as "at least one of a1, a2, ... and an" used in the embodiment of the present application include the situation where any one of a1, a2, ... and an exists alone, and also include any combination of any multiple of a1, a2, ... and an, each of which can exist alone; for example, the description method of "at least one of a, b and c" includes the situation where a is alone, b is alone, c is alone, a and b combination, a and c combination, b and c combination, or abc combination.

[0035] In this application, the terms "first," "second," and the like are used to distinguish between identical or similar items having substantially the same function or effect. It should be understood that "first," "second," and "nth" do not have a logical or temporal dependency, nor do they limit the quantity or order of execution. It should also be understood that although the following description uses the terms "first," "second," and the like to describe various elements, these elements should not be limited by these terms. These terms are simply used to distinguish one element from another.

[0036] In the various embodiments of the present application, unless otherwise specified or there is a logical conflict, the terms and / or descriptions between the various embodiments are consistent and can be referenced by each other. The technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationships.

[0037] Automotive seat comfort refers to the seat's performance in providing users with a comfortable and enjoyable ride, as well as convenient and safe operating conditions. Generally speaking, seat comfort includes static comfort, dynamic comfort, and operational comfort. Static comfort refers to the seat's riding comfort when stationary; dynamic comfort refers to the subjective comfort experienced by the driver or user while the vehicle is in motion; and operational comfort refers to the ease with which the driver or user can operate various functional components within the vehicle.

[0038] The three dimensions of seat comfort perception include seat softness, seat wrapping, and seat support. Within the seat softness dimension, a soft seat touch lays the foundation for seat comfort. Factors influencing seat softness primarily include the hardness of the seat cover or foam material. Within the seat wrapping dimension, the wrapping of the seat is primarily reflected in the seat's side wing design. A good side wing design allows the vehicle to wrap around the outer thighs and sides of the body when cornering, providing good lateral support for the user. Within the seat support dimension, seat support needs to provide support for the lower back and legs separately to alleviate user fatigue.

[0039] As an example, please refer to Figure 1, which shows a conventional seat laminate structure. This conventional seat laminate structure may include a leather or polyvinyl chloride (PVC) layer, a foam layer, a supportive back spring layer, a skeleton layer, and a seat backboard (the seat backboard may be covered with a cover). This conventional seat laminate structure cannot well meet the requirements for seat softness and support. Because the structure simply provides comfort through the foam under the leather or PVC layer, this single layer of foam cannot well meet the user's requirements for the seat, resulting in the seat being too hard or too soft. If the seat is too hard, it cannot meet the user's requirements for softness. If it is too soft, it cannot meet the user's requirements for support.

[0040] To better meet user requirements for seat comfort, embodiments of the present application provide a seat with a highly comfortable laminated structure. This laminated structure provides passengers with a soft seat feel while maintaining excellent support, preventing discomfort caused by insufficient seat support leading to collapse, thereby ensuring excellent passenger comfort.

[0041] The seat provided in the embodiment of the present application includes a backrest and a seat cushion. For example, FIG2 is an exemplary diagram of a seat 100 . As can be seen, the seat 100 includes a backrest 110 and a seat cushion 120 .

[0042] The backrest and seat cushion of the seat provided in the embodiment of the present application are of a laminated structure, each including a cover layer, a foam layer, and a skeleton support layer. For example, as an example, see Figure 3, which shows an exemplary seat laminate structure 300. The seat laminate structure 300 includes a cover layer 310, a foam layer 320, and a skeleton support layer 330. Among them, the cover layer 310 is the top layer of the seat laminate structure 300 and is the layer that comes into direct contact with the user. The foam layer 320 is the middle layer of the seat laminate structure 300, mainly used to meet the user's softness requirements and can also take into account the user's support requirements. Please refer to the following introduction for details, which will not be described in detail here. The skeleton support layer 330 is the bottom layer of the seat laminate structure 300 (optionally, the skeleton support layer 330 can be covered with a cover), mainly used to provide strong support. That is, the foam layer 320 is located between the cover layer 310 and the skeleton support layer 330.

[0043] In one possible implementation, as exemplified in Figure 4 , it can be seen that the cover layer 310 may include a first layer 3101 and a second layer 3102 . The foam layer 320 may include a third layer 3201 and a fourth layer 3202 .

[0044] Exemplarily, the first layer 3101 includes a leather material, a polyurethane material, a polyvinyl chloride material, or a weavable material. The polyurethane material may be, for example, a water-based polyurethane (PU) material. The weavable material may be, for example, cotton, linen, plant fiber, artificial fiber, wool, etc., which is not limited in the present embodiment. Exemplarily, the thickness of the first layer 3101 may be, for example, 1-3 millimeters (mm). It will be understood that the thickness of each layer described in the embodiments of the present application is only an example and does not constitute a limitation on the embodiments of the present application.

[0045] Exemplarily, the second layer 3102 includes a first sponge. Exemplarily, the first sponge may be, for example, a ventilation sponge. In one possible implementation, the second layer 3102 may be a composite layer with the first layer 3101 to form the cover layer 310. Exemplarily, the thickness of the second layer 3102 may be, for example, 3-15 mm.

[0046] Illustratively, the third layer 3201 includes a second sponge. Illustratively, the second sponge may be, for example, a high-elasticity sponge (also known as a high-rebound sponge). Illustratively, the second sponge has a greater resilience than the first sponge. Illustratively, the thickness of the third layer 3201 may be, for example, 10-30 mm.

[0047] Illustratively, the fourth layer 3202 comprises foam. Illustratively, the foam may be, for example, a supportive foam. The supportive foam may be, for example, a foamed resin or polyethylene foam. Illustratively, the thickness of the fourth layer 3202 may be, for example, 20-50 mm. In the embodiments of the present application, the foam may also be referred to as a sponge.

[0048] In a possible implementation, the depression of the fourth layer 3202 may be between 15% and 25%, for example, 20%.

[0049] In the implementation shown in FIG4 , the cover layer 310 comprises a first layer of soft fabric, laminated with a highly flexible ventilated sponge. Furthermore, a foam layer 320 beneath the cover layer 310 is provided with a soft, highly resilient sponge, thereby achieving a comfortable seat surface. Supportive foam is placed beneath the highly resilient sponge to provide support and enhance seat comfort.

[0050] In one possible embodiment, the materials of the third layer 3201 and the fourth layer 3202 may be, for example, polyurethane (PUR). The third layer 3201 is closer to the cover layer 310 than the fourth layer 3202. To provide a softer seat surface, the second sponge in the third layer 3201 has a lower hardness than the foam in the fourth layer 3202. For example, a soft, highly resilient sponge is placed closer to the cover layer 310 to provide a softer seat surface. Furthermore, a more supportive foam with a higher hardness beneath the highly resilient sponge can provide even greater support.

[0051] In one possible implementation, the materials of the second layer 3102 and the third layer 3201 can be, for example, PUR. The foaming hardness of the first sponge in the second layer 3102 can be lower than the foaming hardness of the second sponge in the third layer 3201. In this implementation, because the second layer 3102 is closer to the user, the first sponge in the second layer 3102 is softer than the second sponge in the third layer 3201, providing a better riding experience.

[0052] In a possible implementation, an example can be seen in FIG5 . As can be seen in FIG5 , the foaming layer 320 further includes a fifth layer 3203 .

[0053] For example, the fifth layer 3203 may be a 3D plastic woven fabric (3D Muller). This 3D plastic woven fabric has good ventilation properties, thereby increasing the ventilation of the seat. For example, the thickness of the fifth layer 3203 may be, for example, 10-30 mm.

[0054] In a possible implementation, as shown in FIG. 5 , the fifth layer 3203 is located between the third layer 3201 and the fourth layer 3202 .

[0055] In one possible implementation, in Figure 5 , the positions of the fourth layer 3202 and the fifth layer 3203 may be interchanged. The positions of the two layers may be set according to actual applications, and are not limited in this embodiment of the present application.

[0056] In one possible implementation, as shown in FIG6 , the seat stack structure 300 may further include a sixth layer. The sixth layer may include a heating pad. For example, the sixth layer may have a thickness of 1-3 mm.

[0057] For example, the sixth layer can be provided in the cover layer 310, as shown in FIG6(a) , as shown in the sixth layer 3103. Alternatively, for example, the sixth layer can be provided in the foam layer 320, as shown in FIG6(b) , as shown in the sixth layer 3204. If provided in the foam layer 320, the sixth layer 3204 can be provided close to the cover layer 310 to better provide heating to the user.

[0058] In one possible implementation, see FIG7 for example. FIG7 shows an example of the sixth layer being disposed in the foam layer 320. The sixth layer being disposed in the cover layer 310 is similar and will not be described in detail. As can be seen in FIG7, the foam layer 320 may further include a seventh layer 3205.

[0059] Exemplarily, the seventh layer 3205 includes massage air bags. As shown in Figure 7, the seventh layer 3205 is arranged close to the face cover layer 310 to better provide the massage function to the user. Exemplarily, the thickness of the seventh layer 3205 can be, for example, 5-10 mm.

[0060] In a possible implementation, the depression amount of the portion consisting of the cover layer 310, the third layer 3201 and the seventh layer 3205 can be between 60% and 75%, for example, 70%.

[0061] In one possible implementation, in FIG7 , the positions of the seventh layer 3205 and the third layer 3201 can be interchanged. The positions of the two layers can be set according to actual applications, and the present application does not impose any restrictions on this.

[0062] In one possible implementation, reference may be made to FIG8 , which illustrates a laminated structure 800 of a seat back. The cover layer 810 included in the laminated structure 800 of the seat back may be exemplified by reference to the cover layer 310 shown in any of the aforementioned FIG4 to FIG7 and their possible embodiments. The foam layer 820 included in the laminated structure 800 of the seat back may be exemplified by reference to the foam layer 320 shown in any of the aforementioned FIG4 to FIG7 and their possible embodiments.

[0063] The skeleton support layer 830 included in the laminated structure 800 of the seat back may include an eighth layer 8301 , a ninth layer 8302 , a tenth layer 8303 and an eleventh layer 8304 .

[0064] Exemplarily, the eighth layer 8301 includes a lumbar support. Exemplarily, the lumbar support may be an electrically adjustable pneumatic lumbar support. Exemplarily, the thickness of the eighth layer 8301 may be 5-7 mm.

[0065] Exemplarily, the ninth layer 8302 includes a backrest spring. Exemplarily, the thickness of the ninth layer 8302 can be, for example, 3-7 mm.

[0066] Exemplarily, the tenth layer 8303 comprises a steel skeleton. Exemplarily, the thickness of the tenth layer 8303 may be, for example, 25-35 mm.

[0067] Exemplarily, the eleventh layer 8304 includes a seat back panel. Exemplarily, the thickness of the eleventh layer 8304 can be, for example, 3-5 mm.

[0068] The eighth, ninth, tenth, and eleventh layers 8301, 8302, 8303, and 8304 layers provide strong support to prevent the seat from collapsing or deforming while the user is seated. Furthermore, the electrically adjustable pneumatic lumbar support on the eighth layer 8301 protects the user's lumbar spine and reduces driving fatigue.

[0069] In a possible embodiment, the eighth layer 8301 and / or the ninth layer 8302 may be removed from the skeleton support layer 830. That is, the skeleton support layer 830 may not be provided with an electrically adjustable pneumatic lumbar support and / or a backrest spring to save costs.

[0070] In one possible implementation, to facilitate understanding of the laminated structure of the backrest, please refer to Figure 9 for example. Figure 9 illustrates a schematic diagram of a possible physical laminated structure of the backrest. In this physical laminated structure, the leather / water-based PU is the first layer 3101; the ventilation sponge is the second layer 3102; the comfortable high-elastic sponge is the third layer 3201; the supportive foam resin is the fourth layer 3202; the electric heating system is the sixth layer 3103 or 3204; the electric massage system is the seventh layer 3205; the ventilation system is the fifth layer 3203; the electric adjustable lumbar support is the eighth layer 8301; the high-strength support back spring is the ninth layer 8302; and the high-strength steel frame is the tenth layer 8303. It is understood that the structure shown in Figure 9 is only an example. In a specific implementation, it may also include more or fewer laminated layers, which can be set according to actual application requirements. This embodiment of the application is not limited to this.

[0071] In a possible implementation, please refer to Figure 10 for example. Figure 10 shows a laminated structure 1000 of a seat cushion. The cover layer 1010 included in the laminated structure 1000 of the seat cushion can be exemplified by referring to the cover layer 310 shown in any of the above-mentioned Figures 4 to 7 and their possible embodiments. The foam layer 1020 included in the laminated structure 1000 of the seat cushion can be exemplified by referring to the foam layer 320 shown in any of the above-mentioned Figures 4 to 7 and their possible embodiments. The skeleton support layer 1030 included in the laminated structure 1000 of the seat cushion can include a suspension spring to provide support for the user. By way of example, the thickness of the suspension spring can be, for example, 3-7 mm.

[0072] In a possible implementation, an example can be seen in Figure 11. The seat provided in the embodiment of the present application includes a wing area and a middle block area, and the middle block area is surrounded by the wing area, as shown in Figure 11. In a specific implementation, the supportive foam in the fourth layer 3202 can be set in the wing area of ​​the seat. The high-elastic sponge in the third layer 3201 can also be set in the middle block area. Under this implementation, the soft high-elastic sponge is set in the area where the human body contacts (the middle block area of ​​the backrest and the seat cushion) to ensure a soft feeling in the area where the human body contacts. The supporting wing area adopts a supportive hard foam arrangement to achieve good seat wrapping, so that the vehicle wraps the outer thigh and the side of the body when turning, providing good lateral support for the user. In order to more intuitively show the materials used in the wing area and the middle block area, an example can be seen in Figure 12.

[0073] The structure shown in Figure 12 (a) is composed of highly resilient foam. This structure can be installed in the center section of the seat, as shown in Figure 12 (b). Furthermore, as shown in Figure 12 (b), the seat's lateral wings, which provide support, are also equipped with supportive foam. This ensures excellent seat wrapping, ensuring that the outer thighs and sides of the body are well covered during cornering, providing excellent lateral support for the user.

[0074] In summary, the seat provided in the embodiments of the present application has the following advantages:

[0075] To achieve a superior surface softness, the seat cover is constructed from a soft material (see the description of the first layer 3101 above) and laminated with a highly flexible, ventilated sponge. Comfortable, high-resilience sponge is placed beneath the seat cover layer. The highly flexible fabric, ventilated sponge, and high-resilience sponge provide a soft surface.

[0076] In order to ensure that the seats have a sense of support when passengers sit for a long time, a well-supportive foam (such as foamed resin, etc.) is arranged under the comfortable high-elastic sponge, and a highly supportive 3D muller layer ventilation layer system is arranged. High-elastic support suspension springs and high-strength steel frames are used to provide support, preventing the seats from collapsing and severely deforming when passengers sit.

[0077] In order to meet the comfort requirements of ventilation, heating, massage, etc., the original parts of the ventilation, heating and massage comfort layers are arranged in an orderly manner in the seat stack.
