Description

Technical Field

[0001] This utility model relates to the field of seating technology, and specifically to a seat with stacked layers. Background Technology

[0002] In the automotive industry, seats are key components that provide comfort for drivers and passengers. With technological advancements, the comfort, safety, and functionality of seats have gradually gained importance.

[0003] Current chairs are constructed by incorporating flexible materials such as foam or sponge into the seat frame, with a cover then fixedly attached to the frame. While these flexible materials provide a degree of comfort, the overall appearance and safety of the chair still result in a noticeably hard feel, compromising comfort. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a seat with layers. By setting additional layers on the seat, the layered structure of the seat is increased, thereby improving the comfort of the seat and providing a better riding experience for the user.

[0005] The technical solution to achieve the above objective is a stacked seat, comprising:

[0006] A layered seat includes a foam body and a body cover that at least partially covers the foam body. The layer includes a layered cover and a filler. The layered cover and the body cover are connected to form at least one cavity, and the filler is placed in at least one of the cavities.

[0007] Furthermore, the stacked sleeve includes a surface sleeve and a side sleeve independent of the surface sleeve, and at least one edge of the surface sleeve is connected to the body sleeve through the side sleeve.

[0008] Furthermore, the upper end of the side sleeve is fixedly connected to the surface sleeve, and the lower end of the side sleeve is fixedly connected to or detachably connected to the main body sleeve.

[0009] Furthermore, the stacked cover also includes a back cover connected to the side cover and the main cover, the back cover being disposed in the area where the stacked cover and the main cover overlap.

[0010] Furthermore, the surface sleeve and the body sleeve are connected by a suspension connection, and the surface sleeve, the side sleeve, the suspension connection, and the body sleeve are connected to form multiple cavities.

[0011] Furthermore, the filler is connected to at least one of the surface sleeve, the side sleeve, the clamping device, and the body sleeve to prevent the filler from moving within the cavity.

[0012] Furthermore, the filler is fixedly connected to the stacked surface cover, and a gap is left between the filler and the main body cover.

[0013] Furthermore, the surface cover, the side cover, and the main body cover are connected to form a cavity, the filler is fixedly connected to the stacked cover, and a gap is left between the filler and the main body cover.

[0014] Furthermore, the filler is fixedly connected to the overlay with quilting lines of parallel straight lines or decorative patterns.

[0015] Furthermore, a heating pad base fabric is provided below the stacked layers.

[0016] Furthermore, the heating pad base fabric is disposed between the main body cover and the foamed body, and together with the main body cover, is connected to the stacked cover and the main body cover located outside the stacked coverage area.

[0017] Furthermore, the stacked layers include at least one of a backrest stack, a seat cushion stack, a leg support stack, and a headrest stack.

[0018] Compared with the prior art, this utility model has the following advantages:

[0019] 1. Additional layers are added to the seat, and the cavity formed between the layered cover and the main cover is used to accommodate the filling material. This ensures the original functional and safety requirements of the seat, and also improves the comfort of the seat by adjusting the softness of the filling material.

[0020] 2. At least one edge of the layered surface cover is connected to the main body cover through an independent side cover, creating a relatively upright and floating feel; the middle area of ​​the surface cover is connected to the main body cover by a non-woven fabric suspension, which can ensure the tightness of the main body cover while taking into account the looseness of the layered cover.

[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] See Figure 1 and Figure 2 This utility model provides a layered seat, comprising: a seat frame 1, a foam body 2 disposed on the seat frame 1, and a body cover 3 (e.g., a foam body 2) that at least partially covers the foam body 2. Figure 3 (as shown), 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 positioned at the location where it contacts the person sitting on the seat.

[0039] The stack 4 includes a backrest stack 4a on the backrest, a seat cushion stack 4b on the seat cushion, and a leg rest stack 4c on the leg rest. Although this embodiment shows stacks 4 on the backrest, seat cushion, and leg rest, it is conceivable that stacks 4 could also be provided on at least one of the backrest, seat cushion, and leg rest. It is known that backrests and seat cushions are typically divided into a central area and side areas located on either side of the central area. The backrest stack 4a of this invention can cover a portion of the backrest, for example, only the central area or only the side areas; it can also cover the entire backrest. Similarly, the seat cushion stack 4b can cover a portion of the seat cushion, for example, the central area or side areas, or a U-shaped or annular area formed by the side areas and part of the central area; it can also cover the entire seat cushion. The leg rest stack 4c can at least partially cover the leg rest. It is conceivable that a headrest stack can also be provided on the headrest, and the headrest stack can at least partially cover the headrest.

[0040] The backrest layer 4a, seat cushion layer 4b, leg rest layer 4c, and headrest layer have the same structure. The following example uses seat cushion layer 4b. Figure 3 As shown, the cushion layer 4b covers the central area P and the side wing areas S of the cushion. The cushion layer 4b includes a layered cover 41 and a filling material 42. The layered cover 41 and the main cover 3 are connected to form at least one cavity 43, and each cavity 43 is filled with the filling material 42.

[0041] The laminated 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 comes into contact with the person, and at least one edge of the surface cover 411 is connected to the main cover 3 through the side cover 412 to form the edge of the laminate 4. Specifically, the upper end of the side cover 412 is fixedly connected to the surface cover 411 through a first seam 51, and the lower end of the side cover 412 can be connected to the main cover 3 in either a fixed connection or a detachable connection. As shown in Figure 4(a), a fixed connection means, for example, that the side cover 412 is placed between two pieces of the main cover 3 and fixedly connected to the two pieces of the main cover 3 through a second seam 52, so that the laminate can be firmly fixed to the main cover 3. As shown in Figure 4(b), a detachable connection means, for example, that the side cover 412 and the main cover 3 are fixedly connected to detachable connecting parts A and B respectively, for example, through stitching or adhesive. The detachable connecting parts A and B include the zipper strap, the male and female sides of the Velcro, and the male and female snap fasteners. Thus, the stack 4 can be removed from the main body cover 3 for replacement or cleaning.

[0042] By setting an independent side cover 412 between the surface cover 411 and the main cover 3, instead of the surface cover 411 extending to the side and connecting with the main cover 3, the stacked layer 4 forms a more upright and floating feeling on the main 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 seam 51) is closer to the inside of the seat cushion than the connection position between the side cover 412 and the main cover 3 (such as the position of the seam 52), a layered visual effect of being narrow at the top and wide at the bottom, as shown in Figure 5(a), can be achieved, further increasing the upright and floating feeling; when the connection position between the side cover 412 and the surface cover 411 (such as the position of the seam 51) is farther away from the inside of the seat cushion than the connection position between the side cover 412 and the main cover 3 (such as the position of the seam 52), another layered visual effect of being wide at the top and narrow at the bottom, as shown in Figure 5(b), can be achieved, so that the seam 52 can be covered by the surface cover 411, and the connection position cannot be seen when looking down from above.

[0043] The layered cover 41 may also include a back cover 413 connected to the side cover 412. The back cover 413 is located in the area where the layered cover 41 overlaps with the main cover 3, as shown in Figure 4(c). In particular, the area of ​​the back cover 413 is smaller than that of the surface cover 411, especially near the edge of the layer 4. The upper end of the back cover 413 is connected to the side cover 412 via a third seam 53, and the lower end of the back cover 413 is fixedly connected to the main cover 3 via a fourth seam 54. By providing the back cover 413, the internal space of the cavity 43 can be further increased, thereby allowing more filler 42 to be filled, making the layer 4 more fluffy and comfortable. At the same time, by providing the back cover 413, the layer 4 has a certain amount of expansion and contraction in the height direction, allowing the layer 4 and the main cover 3 to be fixedly connected while also allowing for a certain degree of folding at the edge of the layer 4. Furthermore, in addition to the fixed connection shown in Figure 4(c), the lower end of the back cover 413 can also be connected to the main cover 3 via a detachable connection similar to that shown in Figure 4(b). That is, the back cover 413 and the main cover 3 are respectively fixedly connected to detachable connecting parts A and B. Examples include the chain strap of a zipper, the male and female sides of a Velcro strap, and the male and female snaps of a snap fastener. In this way, the layer 4 can be removed from the main cover 3 for replacement or cleaning.

[0044] The filling material 42 is made of highly elastic, large-particle, and softer flocculent material than the foam body 2, such as pearl cotton, silk floss, comfort foam, goose down, and duck down, making the layer 4 softer and improving comfort. As shown in Figure 8(a), the layered structure 42a obtained by processing silk floss or comfort foam is suitable for layers requiring a smoother appearance. Fluffed pearl cotton, or goose down and duck down, are suitable for layers requiring even higher comfort. As shown in Figure 8(b), fluffed pearl cotton, or goose down and duck down have relatively independent particles. After being wrapped by the filling material cover 421, they form a granular structure 42b and are placed as a whole in the cavity 43. There are certain gaps between the independent particles within the filling material cover 421, allowing for relative movement and deformation. The particle size and spacing of these independent particles both affect the fluffiness of the filling material 42. The filling material cover 421 can limit the shape of the filling material, ensuring a smooth surface of the layer 4. The filling cover 421 can be made of textiles, such as knitted fabric, non-woven fabric, breathable mesh fabric, or mesh elastic fabric.

[0045] The following description, in conjunction with Embodiment 1 and Embodiment 2, details different designs of the middle region of the stack surrounded by the stack edge.

[0046] Example 1

[0047] In addition to the edge of the stack 4, where the surface sleeve 411 is connected to the body sleeve 3 via the side sleeve 412, in other areas covered by the stack 4, the surface sleeve 411 can also be connected to the body sleeve 3 via the clamping 44, such as... Figure 3 , Figures 4(a) to 4(d) As shown, multiple cavities 43 are formed inside the stacked layer 4 by connecting the surface sleeve 411, the side sleeve 412, the clamping 44, and the body sleeve 3. Figure 3 The image shows four cavities, two of which cover the central area P of the cushion, and the other two cover the side wing areas S of the cushion. The surface cover 411 comprises multiple pieces of material, and the body cover 3, which is covered by the stack 4, also comprises multiple pieces of material. As shown in Figure 4(d), two adjacent pieces of the surface cover 411 are fixedly connected to two adjacent pieces of the body cover 3 by a clamping 44. The upper end of the clamping 44 is fixedly connected to two adjacent pieces of the surface cover 411 by a fifth seam 55, and the lower end of the clamping 44 is fixedly connected to two adjacent pieces of the body cover 3 by a sixth seam 56. Furthermore, the clamping 44 can be used solely to separate the cavity and fix the surface sleeve 411 to the main body sleeve 3, or it can be extended and fixed to the foam body 2 to simultaneously fix the main body sleeve 3 to the foam body 2, depending on whether the fixing point of the main body sleeve 3 to the foam body 2 is consistent with the fixing point of the laminate 4 to the main body sleeve 3. The clamping 44 can be made of non-woven fabric, which can ensure the tightness of the main body sleeve 3 while also allowing for a loose feel in the laminate sleeve 41.

[0048] Multiple cavities 43 are formed inside the stack 4 by connecting the surface sleeve 411, the side sleeve 412, the clamping 44, and the body sleeve 3, and each cavity 43 contains a filler 42. The filler 42 in each cavity 43 may be the same or different. More advantageously, the filler 42 may be connected to at least one of the surface sleeve 411, the side sleeve 412, the clamping 44, and the body sleeve 3 to prevent the filler 42 from moving around in the cavity 43.

[0049] Example 2

[0050] like Figures 4(a) to 4(c) Figure 6(a) and Figure 7 As shown, the edge of the layer 4, the surface cover 411 is connected to the main body cover 3 through the side cover 412, forming a cavity 43 inside the layer 4. The cavity 43 covers the central area P and the side wing area S of the cushion in other areas of the layer 4. Correspondingly, a filler 42 covering the central area P and the side wing area S of the cushion in the layer 4 is placed in the cavity 43. The filler 42 is fixedly connected to the surface cover 411 with quilting lines 57 of parallel straight lines or decorative patterns (see Figure 6(a) and 6(b)). Figure 7Specifically, when the filling material is a layered structure 42a as shown in Figure 8(a), the quilting thread 57 directly penetrates the layered structure 42a and fixes it to the surface cover 411. When the filling material is a granular structure 42b as shown in Figure 8(b), the quilting thread 57 penetrates the upper and lower surfaces of the filling material and the filling material cover 421 and is then fixedly connected to the surface cover 411. Both fixing connection methods should ensure that the filling material at the fixing point can be pulled taut to the surface cover 411, so that there is a gap between the filling material 42 and the main body cover 3, especially at the positions corresponding to each quilting thread 57, where more gaps can be formed. As shown in Figure 6(b), the gap at each quilting line 57 position is approximately triangular. Let the thickness of the layered cover 41 be L1, and the gap thickness between the surface cover 411 and the main body cover 3 at the quilting line be L2. Preferably, the gap thickness L2 at the quilting line is about 1 / 2 to 2 / 3 of the thickness L1 of the layered cover 41.

[0051] When the foam body 2 has a concave surface on the side closest to the person, due to the sewing process and the material of the cover, more gaps tend to form between the filler 42 and the cover 3. This means the base of the approximately triangular gap widens outwards, resulting in a larger volume. In this case, noticeable wrinkles can be seen on the surface cover 411. Conversely, when the foam body 2 has a convex surface on the side closest to the person, the base of the approximately triangular gap narrows inwards, resulting in a smaller volume. In this case, the surface cover 411 is relatively smoother. Figure 9 As shown, when a person sits on the seat, the layer 4 is compressed, and the air between the main body cover 3 and the filling 42, as well as the air inside the filling 42, is expelled. Areas subjected to greater pressure F deform more and expel more air, while areas subjected to less pressure F deform less, maintaining strong support for the person and achieving a close fit with the body for a stronger sense of enclosure. Because more gaps are added at the quilting, the seat cushion has more space to be compressed when subjected to pressure F, further improving enclosure and comfort. When the person leaves the seat, the highly elastic, large-particle filling can quickly absorb air, meeting the rebound requirements and maintaining the shape and contour.

[0052] When the area requiring the layer 4 is large, multiple cavities 43 can be formed inside the layer 4 as needed. The formation method of each cavity 43 and the connection method between adjacent cavities 43 are the same as in Embodiment 1. The fixing method of the filling material 42 in each cavity 43 can all adopt the quilted connection method of Embodiment 2. Alternatively, the quilted connection method can be adopted according to the size of each cavity 43. For example, the quilted connection method of Embodiment 2 can be used at the middle block area P, while the connection method of Embodiment 1 can be used at the side wing area S. That is, the filling material 42 is connected to at least one of the surface cover 411, side cover 412, clamping 44 and body cover 3 using a non-quilted method, which can prevent the filling material 42 from moving around in the cavity 43.

[0053] A heating pad base fabric 6 can also be provided below the layer 4 to enable the seat with the layer 4 to have a heating function. Specifically, the heating pad base fabric 6 is located between the main body cover 3 and the foam body 2, and together with the main body cover 3, it is connected to the layer cover 41 and the main body cover 3 located outside the area covered by the layer 4. The heating pad base fabric 6 covers the front of the foam body 2, and the main body cover 3 covers the front of the heating pad base fabric 6. When fixing the layer 4, as shown in Figure 4(d), the two adjacent pieces of the surface cover 411, the two adjacent pieces of the main body cover 3, and the heating pad base fabric 6 can be simultaneously fixed and connected by the suspension 44 through the fifth seam 55 and the sixth seam 56. The heating pad base fabric 6 can also be pre-fixed (e.g., sewn) to the back of the main body cover 3 or fixed (e.g., glued) to 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 heat loss during the heat transfer process. For cases where the heating pad base fabric 6 is pre-fixed to the main body cover 3, when fixing the layer 4, the entire heating pad base fabric 6 and the main body cover 3 can be connected to the main body cover 3 and the layer cover 41 outside the coverage area of ​​the layer 4 by sewing using the clamping 44. For cases where the heating pad base fabric 6 is pre-fixed to the foam body 2, when fixing the layer 4, it is only necessary to connect the main body cover 3 to the main body cover 3 and the layer cover 41 outside the coverage area of ​​the layer 4 by sewing using the clamping 44. The heating pad base fabric 6 can be made of breathable 3D mesh fabric or non-woven fabric. Using breathable 3D mesh fabric also helps to reduce the impact of the heating pad base fabric 6 on the seat ventilation function.

[0054] The layered cover 41 comprises one or more of genuine leather, artificial leather, and fabric. Preferably, the layered cover 41 is made of smooth leather or perforated leather to improve its breathability and ventilation, and ultra-soft PVC is used to improve the comfort of the layer 4. The main cover 3 comprises one or more of genuine leather, artificial leather, fabric, and breathable 3D mesh. The layered cover 41 and the main cover 3 in the visible area can be made of the same material to provide the same appearance; the layered cover 41 and the main cover 3 in the visible area can also be made of different materials to meet different needs.

[0055] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
