[0002] In the automotive industry, seats are key components that provide comfort for drivers and passengers. With the development of technology, the comfort, safety and functionality of seats have gradually received more attention.

[0003] It is known that the current seat is to set a flexible material such as foam or sponge on the seat frame, and cover the flexible material with a cover fixedly connected to the seat frame. Although the flexible material can make people feel comfortable to a certain extent when sitting on the seat, in order to ensure the appearance and safety of the seat, the flexible material of the seat still has a noticeable hard touch, making the seat less comfortable. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the prior art and provide a seat with laminated layers. By arranging additional laminated layers on the seat, the hierarchical structure of the seat is increased and the comfort of the seat is improved. The laminated layers can produce more adaptive deformation amounts based on the different pressures applied to different areas, thereby better fitting the human body and providing a stronger wrapping feeling.

[0035] See also Figure 1 As shown in FIG. 3 , the present invention provides a seat with a laminate, comprising: a seat frame 1, a foam body 2 arranged on the seat frame 1, a body cover 3 at least partially covering the foam body 2, and a laminate 4 laid on the outer surface of the foam body 2 or the outer surface of the body cover 3. The laminate 4 is basically arranged at a position in contact with a person sitting on the seat.

[0036] The stack 4 includes a backrest stack 4a provided on the backrest, a cushion stack 4b provided on the seat cushion, and a leg rest stack 4c provided on the leg rest. Although the stack 4 is provided on the backrest, the seat cushion, and the leg rest in this embodiment, it is conceivable that the stack 4 may also be provided on at least one of the backrest, the seat cushion, and the leg rest. It is known that the backrest and the seat cushion are usually divided into a middle block area and wing areas located on both sides of the middle block area. The backrest stack 4a of the present invention may cover a part of the backrest, for example, only the middle block area or only the wing area; or it may cover the whole area of ​​the backrest. Similarly, the cushion stack 4b may cover a part of the seat cushion, for example, the middle block area or the wing area of ​​the seat cushion, or the U-shaped area or the annular area formed by the wing area and part of the middle block area, or it may cover the whole area of ​​the seat cushion. The leg rest stack 4c may at least partially cover the leg rest. It is conceivable that a headrest stack may also be provided on the headrest, and the headrest stack may at least partially cover the headrest.

[0037] The backrest laminate 4a, the cushion laminate 4b, the leg support laminate 4c and the headrest laminate have the same structure. The cushion laminate 4b is taken as an example below. Figure 4 As shown, the cushion layer 4b covers the middle block area P and the side wing area S of the cushion, and the cushion layer 4b includes a laminated layer cover 41 and a filler 42; the laminated layer cover 41 and the main body cover 3 are connected to enclose at least one cavity 43, and a filler 42 is placed in each cavity 43. The filler 42 is fixedly connected to the laminated layer cover 41, and a gap is left between the filler 42 and the main body cover 3.

[0038] Specifically, the laminated layer cover 41 includes a surface cover 411 and a side cover 412 independent of the surface cover 411. When an occupant sits on the seat, the surface cover 411 contacts the person, and at least one side edge of the surface cover 411 is connected to the main body cover 3 through the side cover 412 to form the edge of the laminate 4.

[0039] Different designs of the middle region of the laminate surrounded by the edge of the laminate are described below in combination with the first embodiment and the second embodiment.

[0040] Embodiment 1

[0041] See Figure 3 to Figure 6 As shown, at the edge of the laminate 4, the surface cover 411 is connected to the main body cover 3 through the side cover 412, and a cavity 43 is formed inside the laminate 4. The cavity 43 covers the middle block area P and the side wing area S of the cushion in the laminate 4. Accordingly, a filler 42 covering the middle block area P and the side wing area S of the cushion in the laminate 4 is placed in the cavity 43. The filler 42 is fixedly connected to the surface cover 411 by a quilting line 57 of a parallel straight line or a decorative pattern, as shown in FIG. Figure 4As shown, the quilting line 57 penetrates the fixed filler 42, and tightens the filler at the fixed position to the surface cover 411, so that a gap is left between the filler 42 and the main body cover 3, especially more gaps can be formed at the position corresponding to each quilting line 57. As shown in FIG3(b), the gap corresponding to the position of each quilting line 57 is approximately triangular, and the thickness of the laminated surface cover 41 is L1, and the gap thickness between the surface cover 411 and the main body cover 3 at the quilting line is L2. Preferably, the gap thickness L2 at the quilting line is about 1 / 2 to 2 / 3 of the thickness L1 of the laminated surface cover 41.

[0042] When the side of the foam body 2 close to the person forms a concave surface, affected by the sewing process and the cover material, more gaps are easily formed between the filler 42 and the face cover 3, that is, the bottom edge of the gap that is approximately triangular expands outward, and the volume presented is larger. At this time, obvious wrinkles can be seen on the surface cover 411. On the contrary, when the side of the foam body 2 close to the person forms a convex surface, the bottom edge of the gap that is approximately triangular retracts inward, and the volume presented is smaller. At this time, the surface cover 411 is relatively flatter. Figure 6 As shown, when a person sits on the seat, the laminate 4 is squeezed, and the air between the main body cover 3 and the filler 42 and the air inside the filler 42 are discharged. The area with a large pressure F has a large deformation amount and a large amount of air discharged. The area with a small pressure F has a small deformation amount, which still provides strong support for the person, thereby achieving a fit effect with the person and a stronger wrapping feeling. Because more gaps are added at the quilting, when the seat cushion is subjected to pressure F, there are more gaps to provide compressed space, which can further improve the wrapping and comfort. When a person leaves the seat, the filler can quickly inhale air to meet the rebound requirements and ensure the contour of the shape.

[0043] The filler 42 is made of a flocculent material with high elasticity, large particle size, and softer than the foam body 2, such as pearl cotton, silk cotton, comfort foam, goose down, duck down, etc., so that the laminate 4 is softer to improve comfort. Among them, as shown in Figure 5 (a), the layered structure 42a obtained by processing silk cotton or comfort foam is suitable for laminates that require a smoother appearance. Pearl cotton that has been fluffed, or goose down and duck down are suitable for laminates that require higher comfort. As shown in Figure 5 (b), the pearl cotton that has been fluffed, or goose down and duck down have relatively independent particles, which are wrapped by the filler cover 421 to obtain a granular structure 42b and are placed in the cavity 43 as a whole. There is a certain gap between the independent particles in the filler cover 421, which can be relatively movable and deformed. The particle size and spacing of the independent particles affect the fluffiness of the filler 42. The overall shape of the filler 42 can be limited by the filler cover 421. For the first embodiment, when the filler is a layered structure 42a as shown in FIG5(a), the quilting thread 57 directly penetrates the layered structure 42a and fixes it to the surface cover 411. When the filler is a granular structure 42b as shown in FIG5(b), the quilting thread 57 penetrates the filler and the upper and lower surfaces of the filler cover 421 and is fixedly connected to the surface cover 411. Both fixed connection forms should ensure that the filler at the fixed position can be tightened to the surface cover 411, so that a gap is left between the filler 42 and the main body cover 3. The filler cover 421 can be made of textiles, such as one of knitted fabrics, non-woven fabrics, breathable mesh fabrics, and mesh stretch fabrics.

[0044] For the connection of the edge of stack 4, see Figure 8(a) to Figure 8(c) As shown, the upper end of the side cover 412 is fixedly connected to the surface cover 411 by the first stitching 51, and the connection mode between the lower end of the side cover 412 and the main body cover 3 can be selected from one of the two types of fixed connection and detachable connection. Among them, as shown in Figure 8 (a), the fixed connection refers to, for example, the side cover 412 is placed between the area covered by the laminate 4 and the uncovered area of ​​the main body cover 3, and is fixedly connected to the material sheets of the two areas of the main body cover 3 by the second stitching 52, so that the laminate can be firmly fixed on the main body cover 3. As shown in Figure 8 (b), the detachable connection refers to, for example, the side cover 412 and the main body cover 3 are fixedly connected to the detachable connecting counterparts A and B respectively, for example, by stitching or glue. The detachable connecting counterparts A and B include the chain of the zipper, the male and female surfaces of the Velcro, and the male and female buckles of the snap fastener. In this way, the laminate 4 can be removed from the main body cover 3 for replacement or cleaning.

[0045] By arranging an independent side cover 412 between the surface cover 411 and the main body cover 3 instead of extending the surface cover 411 to the side to connect with the main body cover 3, the laminate 4 forms a more upright suspension feeling on the main body cover 3. In the left-right direction of the vehicle, when the connection position between the side cover 412 and the surface cover 411 (such as the position of the stitching 51) is closer to the inside of the seat cushion than the connection position between the side cover 412 and the main body cover 3 (such as the position of the stitching 52), a visual effect of the laminate being narrow at the top and wide at the bottom extending outward as shown in FIG9(a) can be achieved, further increasing the upright sense of suspension; when the connection position between the side cover 412 and the surface cover 411 (such as the position of the stitching 51) is farther away from the inside of the seat cushion than the connection position between the side cover 412 and the main body cover 3 (such as the position of the stitching 52), another visual effect of the laminate being wide at the top and narrow at the bottom contracting inward as shown in FIG9(b) can be achieved, so that the stitching 52 can be blocked by the surface cover 411, and the connection position cannot be seen from top to bottom.

[0046] The laminated surface cover 41 may also include a back cover 413 connected to the side cover 412, and the back cover 413 is arranged in the area where the laminated surface cover 41 overlaps with the main body cover 3, as shown in Figure 8 (c), especially near the edge of the laminated layer 4, the area of ​​the back cover 413 is smaller than the surface cover 411. The upper end of the back cover 413 is connected to the side cover 412 through the third suture 53, and the lower end of the back cover 413 is fixedly connected to the main body cover 3 through the fourth suture 54. By providing the back cover 413, the internal space of the cavity 43 can be further increased, and then more fillers 42 can be filled, making the laminated layer 4 more fluffy and comfortable. At the same time, by providing the back cover 413, the laminated layer 4 has a certain amount of expansion and contraction in the height direction, allowing the laminated layer 4 and the main body cover 3 to ensure fixed connection, and a certain degree of folding can be achieved at the edge of the laminated layer 4. Furthermore, the connection between the lower end of the back cover 413 and the main body cover 3 can be selected as a fixed connection as shown in FIG8(c), or a detachable connection similar to that shown in FIG8(b), that is, the back cover 413 and the main body cover 3 are fixedly connected to detachable counterparts A and B, respectively. For example, the zipper belt, the male and female surfaces of Velcro, and the male and female buckles of snap fasteners. In this way, the laminate 4 can be removed from the main body cover 3 through this for replacement or cleaning.

[0047] Embodiment 2

[0048] See also Figure 7As shown in FIG. 9 , when the area where the laminate 4 needs to be set is large, a plurality of cavities 43 can be formed inside the laminate 4 as needed. The connection structure of the edge of the laminate 4 is the same as that of the first embodiment, and will not be repeated here. In addition to the edge of the laminate 4, the surface cover 411 is connected to the main body cover 3 through the side cover 412. In other areas covered by the laminate 4, the surface cover 411 can also be connected to the main body cover 3 by tightening 44, such as Figure 7 8 (d), through the surface cover 411, the side cover 412, the suspension 44 and the main body cover 3 are connected to form a plurality of cavities 43 inside the laminate 4, Figure 7 There are four cavities shown in the figure, of which two cavities cover the middle block area P of the cushion, and the other two cavities cover the side wing area S of the cushion. The surface cover 411 includes multiple pieces of material, and the main body cover 3 covered by the laminate 4 also includes multiple pieces of material. As shown in Figure 8(d), two adjacent pieces of material of the surface cover 411 are fixedly connected to two adjacent pieces of material of the main body cover 3 by a sling 44. The upper end of the sling 44 is fixedly connected to the two adjacent pieces of material of the surface cover 411 by a fifth stitch 55, and the lower end of the sling 44 is fixedly connected to the two adjacent pieces of material of the main body cover 3 by a sixth stitch 56. Furthermore, the suspension 44 can be used only to separate the cavity and fix the surface cover 411 to the body cover 3, or it can be extended and fixed to the foam body 2 to realize the fixation of the body cover 3 to the foam body 2, which depends on whether the fixed point position of the body cover 3 and the foam body 2 is consistent with the fixed point position of the laminate 4 and the body cover 3. The suspension 44 can be made of non-woven fabric, which can ensure the tightness of the body cover 3 and take into account the looseness of the laminate surface cover 41.

[0049] Through the connection of the surface cover 411, the side cover 412, the suspension 44 and the main body cover 3, a plurality of cavities 43 are formed inside the laminate 4, and a filler 42 is placed partially or completely in each cavity 43. The fillers 42 in each cavity 43 can be the same or different. The fixing form of the fillers 42 in each cavity 43 can all adopt the quilting line connection form of the first embodiment. The quilting line connection form can also be adopted according to the size of each cavity 43. For example, the quilting line connection form of the first embodiment is adopted in the middle block area P, and the filler 42 in the wing area S can be connected with at least one of the surface cover 411, the side cover 412, the suspension 44 and the main body cover 3 in a non-quilting line form, as long as the filler 42 is prevented from moving in the cavity 43.

[0050] Preferably, for the first and second embodiments, a heating pad base cloth 6 can also be provided below the laminate 4 so that the seat with the laminate 4 has a heating function. Specifically, the heating pad base cloth 6 is provided between the main body cover 3 and the foam body 2, and together with the main body cover 3, is connected to the laminate surface cover 41 and the main body cover 3 outside the coverage area of ​​the laminate 4. The heating pad base cloth 6 covers the front side of the foam body 2, and the main body cover 3 covers the front side of the heating pad base cloth 6. When the laminate 4 is fixed, as shown in FIG8(d), the two adjacent pieces of material of the surface cover 411 and the two adjacent pieces of material of the main body cover 3 and the heating pad base cloth 6 can be fixedly connected at the same time by the fifth stitch 55 and the sixth stitch 56 by the tightening 44. The heating pad base cloth 6 can also be pre-fixed (such as sewing) on ​​the back of the main body cover 3 or fixed (such as pasting) on ​​the front of the foam body 2, so that it forms a whole with the main body cover 3 or the foam body 2. This method can reduce the loss in the heat transfer process. In the case of pre-fixing on the main body cover 3, when fixing the laminate 4, the heating pad base cloth 6 and the main body cover 3 can be connected to the main body cover 3 and the laminate layer cover 41 outside the coverage area of ​​the laminate 4 by sewing by tightening 44. In the case of pre-fixing on the foam body 2, when fixing the laminate 4, it is only necessary to connect the main body cover 3 and the main body cover 3 and the laminate layer cover 41 outside the coverage area of ​​the laminate 4 by sewing by tightening 44. The heating pad base cloth 6 can be made of breathable 3D mesh or non-woven fabric. The use of breathable 3D mesh is also conducive to reducing the influence of the heating pad base cloth 6 on the seat ventilation function.

[0051] The laminated surface cover 41 includes one or more of genuine leather, artificial leather, and fabric. Preferably, the laminated surface cover 41 uses smooth leather or perforated leather to improve the air permeability and ventilation function of the laminated surface cover 41, and the laminated surface cover 41 uses ultra-soft PVC to improve the comfort of the laminate 4. The main body cover 3 includes one or more of genuine leather, artificial leather, fabric, and breathable 3D mesh. The laminated surface cover 41 and the main body cover 3 in the visible area can be made of the same material to provide the same appearance; the laminated surface cover 41 and the main body cover 3 in the visible area can also be made of different materials to meet different needs.

[0052] The present invention is described in detail above in conjunction with the embodiments of the accompanying drawings. A person skilled in the art can make various variations of the present invention according to the above description. Therefore, certain details in the embodiments should not constitute a limitation of the present invention, and the scope of protection of the present invention shall be defined by the scope of the attached claims.
