Covered by seat cover

Abstract

To prevent marks caused by contact and rubbing of seam allowances of a stitched part from remaining when a seat cover is removed. [Solution] In a seat cover (11) constructed by joining sheet materials (15) together in the surface direction, at least a portion of the joining portion between the sheet materials (15) is constructed with a stitched portion (16) in which the edges of each sheet material (15) are sewn together, leaving a seam allowance (16a) exposed on the back surface. The stitched portion (16) has a non-matching stitched portion that does not match a depression in the pressurized surface of the object to be covered (12). A buffer sheet (13) is provided on the contact surface that comes into contact with the object to be covered (12), which is the back surface, covering the non-matching stitched portion and interposing it between the object to be covered.

Description

[Technical Field]

[0001] The present invention relates to a seat cover for use on seats provided in vehicles such as automobiles and facilities such as theaters. [Background technology]

[0002] Seats, particularly car seats, are covered with a predetermined cover in advance, and are designed to provide a beautiful appearance and comfortable seating.

[0003] However, there is a demand from users to obtain the appearance and comfort they prefer, and as disclosed in Patent Document 1 below, for example, a seat cover of their choice is applied over a pre-covered cover.

[0004] Since seat covers have a three-dimensional shape, they are formed by joining, or sewing together, multiple sheet materials in the surface direction. The sheet materials are sewn together at their edges, and there are quite a few stitching sections in which the edge beyond the stitching line, or the seam allowance, is exposed on the back surface (see Figure 5 of Patent Document 1).

[0005] The seam allowance is generally stiff because the edges of the sheet members are compressed and tightly joined to form a line. In particular, it becomes even stiffer when the sheet members have a synthetic leather-like sheet material on the surface.

[0006] For this reason, in a configuration in which the seam allowance of the stitched portion is exposed on the backside, as shown in FIG. 9, the seam allowance 101 comes into contact with the object to be covered 102, and when a load is applied when sitting down, only that part hits the object to be covered 102 hard. In particular, in the case of car seats, in addition to the load, movement due to vibrations and the like also occurs, which can cause linear scratches that look like they have been caused by rubbing on the cover that has already been covered on the seat. The scratch-like marks appear as lines, as if the color has been rubbed off. The scratches mainly occur in areas where the seam allowance is visible on the backside, in areas that do not match the depressions in the three-dimensional shape of the surface of the cover that is to be covered.

[0007] [Patent Document 1] Registered Utility Model No. 3119792 Summary of the Invention [Problem to be solved by the invention]

[0008] The main object of this invention is to prevent the seam allowance of the stitching from coming into contact with the object to be covered to such an extent that it may cause injury. [Means for solving the problem]

[0009] The seat cover of this invention achieves this goal. Covering structure by has the following structure: Chishi It is made by joining two mating materials together in the surface direction. Covering structure using a seat cover that covers an object to be covered teeth, The covering object is a cover that covers the surface of a seat, and the seat cover At least a part of the joining portion between the sheet materials is formed by a seam portion in a manner in which the edges of the sheets are sewn together and the seam allowance is exposed on the back surface. At least part of Non-matching seams that do not match the depressions on the pressurized surface of the object to be covered The back surface of the seat cover is formed to a size that can cover the pressure-applied surface of the object to be covered. Non-compatible sutures and Between the object to be covered Relative displacement possible It is provided with an intervening buffer sheet.

[0010] In this type of seat cover, the cushioning sheet is interposed between the seat cover and the object to be covered, thereby performing a cushioning function. In other words, it prevents the seam allowance of the stitching from directly contacting the object to be covered and also alleviates the concentration of load. [Effects of the Invention]

[0011] According to this invention, the cushioning sheet is configured to soften the contact of the seam allowance of the stitching, preventing damage to the object being covered. In other words, it prevents marks from being left when the seat cover is removed. Furthermore, since the seam allowance is not directly and strongly pressed against the object being covered and rubbed, it is also possible to prevent color transfer from the seam allowance to the object being covered. Therefore, if the object being covered is a cover that has already been applied to a seat, the seat can be maintained in like-new condition. Furthermore, since it is easier to create non-matching seam portions, it contributes to expanding the range of seat cover designs and simplifying the sewing process.

DETAILED DESCRIPTION OF THE INVENTION

[0013] An embodiment of the present invention will be described below with reference to the drawings.

[0014] The seat cover 11 is configured not to scratch the object to be covered 12. In other words, in order to prevent scratches from being left on the object to be covered 12 when the seat cover 11 is removed, a buffer sheet 13 is provided on the surface that comes into contact with the object to be covered 12, as shown in an enlarged portion of FIG.

[0015] The seat cover 11 includes a seat portion seat cover 11a that is attached to the seat portion 14a of the seat 14 and a backrest seat cover 11b that is attached to the backrest 14b so as to individually cover each part of the seat 14. If necessary, the seat cover may also include a headrest seat cover 11c that covers the headrest 14c and an armrest seat cover (not shown) that covers the armrest (not shown). Each seat cover 11 is formed in a three-dimensional shape that corresponds to the surface shape of each part of the seat, and is configured so that it can be attached by being fitted over it.

[0016] In this example, the direct covering object 12 of the seat cover 11 is a cover (hereinafter referred to as "lower cover 12a") that covers the surface of the seat 14, and the shape of the seat cover 11 and the shape of the lower cover 12a are different from each other. In other words, the seat cover 11 is configured to achieve the desired aesthetic feel and comfort regardless of the lower cover 12a, and the positions and shapes of the joining parts for joining the sheet materials 15 together in the surface direction to create the three-dimensional shape, that is, the seams 16, are naturally different.

[0017] At least some of the seams 16 have a configuration in which the edges of the sheets 15 are sewn together, exposing the seam allowance 16a on the back surface. Among these seams 16, those that do not match with the depressions on the pressurized surface of the object to be covered 12 are referred to as non-matching seams. The seams 16 formed on the seat cover 11 may be partially or entirely non-matching seams. The seams 16 may also have a configuration in which the seam allowance 16a is enclosed inward, in which case the seams 16 may at least partially match with the depressions on the pressurized surface of the object to be covered 12, or may not match at all.

[0018] The "pressurized surface" is the part that receives pressure during use, and is generally the upper surface of the seat 14a, or the front surface of the backrest 14b. In particular, the parts of the pressure-receiving surface that correspond to the bulging parts of the human body are the parts that receive the most pressure, while the edge parts are the parts that are less likely to receive pressure.

[0019] FIG. 2 is a perspective view of the seat 14 with the seat covers 11 covering it, and FIG. 3 is a perspective view of the seat 14 with the seat covers 11 removed.

[0020] As shown in Figure 3, the upper surface of the seat portion 14a has a three-dimensional recess. Specifically, the seat portion 14a has two recesses 41 extending in the front-rear direction on both the left and right sides, and one recess 42 extending in the left-right direction in the front between the left and right recesses 41. These recesses 41, 42 are seams (transitions) where the sheet material 15 constituting the lower cover 12a is sewn together. While the upper surface of the seat portion 14a has recesses 41, 42 of this shape, the seat portion seat cover 11a has seams 16 of a different shape at different positions from the recesses 41, 42 of the lower cover 12a. Specifically, there are five seams 61 extending in the front-rear direction in a region excluding the front portion, and a wide U-shaped seam 62 at the front end that widens in the left-right direction from the portion containing the seams 61.

[0021] The front surface of the backrest 14b also has a three-dimensional recess. Specifically, the backrest 14b has two recesses 45 extending in the vertical direction on both the left and right sides. These recesses 45 are not the seams between the sheets constituting the lower cover 12a, but are linear recesses. While the front surface of the backrest 14b has such recesses 45, the backrest seat cover 11b has seams 16 at positions different from the recesses 45 on the lower cover 12a. Specifically, these seams are three seams 65 extending in the vertical direction from the center in the vertical middle portion, two seams 66 extending in a manner that curves sharply outward in the horizontal direction, and a wide U-shaped seam 67 at the top that is wider in the horizontal direction than the portion with the five seams 65, 66.

[0022] The positions and shapes of the seams 16 of the seat cover 11 and the recesses 41, 42, 45 of the lower cover 12a may not match in all parts, but may match in part. In other words, at least part of the seams 16 is a non-matching seam.

[0023] Although the seat cover 11a and the back cover 11b have different shapes, they have the same basic structure, so in the following explanation, the structure of the seat cover 11a will be explained instead of the back cover 11b.

[0024] In addition, although the seat 14 is shown in FIG. 3, the lower cover 12a is not shown.

[0025] The seat cover 11a is made up of multiple sheet parts that cover the upper surface, front, and left and right side surfaces of the seat 14a, and among these, the upper sheet part 71 that covers the upper surface of the seat 14a in particular is made up of multiple joined sheet materials 15. The boundaries between the sheet materials 15 are the parts separated by the seams 61 and 62 mentioned above. Specifically, the sheet materials 15 include a front sheet material 51 located in front of the seat 14a, four rear sheet materials 52 located further rearward and divided into four in the left-right direction, and side sheet materials 53 located on either side of the front sheet material 51 and rear sheet material 52.

[0026] The front seat material 51 and the rear seat material 52 are made of a highly cushioned seat material 81. As shown in Figure 4, the seat material 81 has a five-layer structure. That is, from the surface side, there are a leather layer 82 with fine through-holes, a base fabric 83 made of tricot fabric, a high-density cotton layer 84, a low-resilience sponge layer 85, and a lining 86 made of tricot fabric. Each layer is bonded together to form a single unit.

[0027] The side sheet material 53 is made of a sheet material that is thinner than the sheet material 81 that constitutes the front sheet material 51 and the rear sheet material 52. This sheet material can be configured in the above-mentioned five-layer structure excluding the low-resilience sponge layer 85. In addition, the leather layer 82 is not punched and has no through holes.

[0028] The same thin sheet material as the side sheet material 53 is used for the front sheet portion 72 and side sheet portions 73 around the upper sheet portion 71, and for the extension piece 71a at the rear end of the upper sheet portion 71.

[0029] The joining of the sheet materials 15 is configured by seams 16 in a manner that exposes the seam allowances 16a on the back side of the seam line of the sewn edge portions, except for the seam 16 between the rear sheet material 52 and the side sheet material 53. This is shown in Figure 5. Figure 5 is a schematic diagram showing the seams 16 between the front sheet material 51, the rear sheet material 52, the side sheet material 53, and the side sheet portion 73 as viewed from the back side. All of the seam allowances 16a protrude to the back side, and are either standing or lying flat.

[0030] The seam 16 between the side sheet material 53 and the side sheet portion 73, in other words the seam 16 surrounding the upper sheet portion 71, is stitched for decoration, with two parallel stitches 16b provided. These stitches 16b are located at the corners where the surfaces of the object 12 intersect when the object 12 is covered.

[0031] The seam 16 between the rear sheet material 52 and the side sheet material 53 is in a state where the seam allowance is wrapped inside without being exposed.

[0032] The back surface having the stitched portions 16, i.e., the contact surface of the seat cover 11a that comes into contact with the object to be covered, is provided with a buffer sheet 13 as shown in Figures 6 and 7. The buffer sheet 13 is made of a sheet material made of elastic open-cell sponge, and is positioned between the object to be covered 12 and the back surface, covering at least the non-matching stitched portions of the stitched portions 16.

[0033] As shown in FIG. 7, the buffer sheet 13 is not joined to the contact surface of the seat cover 11a, and is displaceable relative to the contact surface.

[0034] The buffer sheet 13 is formed to a size corresponding to the pressure-receiving surface of the object 12 to be covered or to a size capable of covering the pressure-receiving surface, with a portion of its edge fixed to the contact surface. Specifically, as shown in FIG. 6 , the portion of the edge refers to both ends in the front-to-rear or up-to-down direction corresponding to the up-to-down direction of the seated person's body, within the portion of the contact surface (the underside of the upper sheet portion 71) that corresponds to the pressure-receiving surface of the object to be covered. The buffer sheet 13 is fixed across the entire width (in the left-to-right direction) with respect to the seams 16 at positions corresponding to the front-to-rear or up-to-down ends of the buffer sheet 13, and the fixed portion 13a is linear. The buffer sheet 13 may be fixed at either end instead of both ends, but fixing at both ends makes handling during covering easier. It is also possible to fix at least one end in the left-to-right direction instead of the front-to-rear or up-to-down direction.

[0035] Regarding the size of the buffer sheet 13, its contour shape should be set so that the buffer sheet 13 approaches or reaches the corners of the surface of the object to be covered 12 that has a pressure-receiving surface. That is, as shown in Fig. 6, the buffer sheet 13 is formed to a size that approaches or reaches the front-rear and left-right edges of the back surface of the upper sheet portion 71 that contacts the surface of the object to be covered 12 that has a pressure-receiving surface, i.e., the seam 16 with the stitches 16b. Preferably, the buffer sheet 13 is slightly smaller. This is because the buffer sheet 13 is located on the back surface side and therefore faces inward when covered.

[0036] The thickness of the buffer sheet 13 may be any thickness as long as it has a buffering function, and in the case of a general foamed sponge sheet, the thickness may be, for example, about 10 mm.

[0037] Regarding the mode of the buffer sheet 13, if the seat to which it is to be used has a seat ventilation function, a sponge sheet having through holes 13b as shown in FIG. 8 can be used for the buffer sheet 13.

[0038] The seat cover 11 constructed as described above is used by covering the corresponding part of the seat in the usual way. During the covering, the buffer sheet 13 is not fixed all around but has a high degree of freedom, that is, the buffer sheet 13 can move relative to the contact surface, so it is easy to cover appropriately without wrinkles or steps.

[0039] The buffer sheet 13 is formed to a size that is close to or reaches the corners of the surface of the object 12 that has a pressure-receiving surface, and covers the entire surface that has a pressure-receiving surface when covered. As a result, all of the seams 16, including the seams 16 that expose the seam allowances 16a, are covered by the buffer sheet 13. This provides a more comfortable sitting experience than when the seam allowances 16a are only partially covered. In particular, even if the left-right contour of the buffer sheet 13 is close to the boundary (the seam 16 with the stitching 16b) between the top sheet portion 71 and the front sheet portion 72 and the side sheet portion 73, the buffer sheet 13 can also cover the seam 16 with the stitching 16b. This is because the buffer sheet 13 is located on the contact surface.

[0040] When a seated person sits on the seat cover 11 and the load is applied, the seam 16 is pressed, forcing the seam allowance 16a against the object 12. However, because the buffer sheet 13 is interposed between the seat cover 11 and the object 12, direct contact of the seam allowance 16a is avoided, dispersing the load. This prevents localized pressure on the object 12, which could cause scratches. Furthermore, because the seam allowance 16 does not come into direct contact with the object 12, there is no color transfer from the seam allowance 12 to the object 12. As a result, if the object 12 is a lower cover 12a that has already been installed on the seat, the seat 14 can be maintained in like-new condition. Furthermore, the seat cover 11 can be designed to incorporate non-matching seams, broadening the design options for the seat cover 11. Furthermore, by designing all seams 16 so that the seam allowance 16a is exposed, the sewing process can be simplified.

[0041] The above configuration is one embodiment for carrying out the present invention, and the present invention is not limited to only the above configuration, and other configurations can also be adopted.

[0042] For example, the object 12 to be covered may be a seat without a lower cover 12 a , in which case the seat becomes the object 12 to be covered directly.

[0043] The buffer sheet 13 may be provided on a part of the surface having the pressure-receiving surface rather than on the entire surface, or may be provided separately from the sheet cover and sandwiched in between when covering, or may be fixed to the contact surface with double-sided tape or the like.

[0044] The buffer sheet 13 may be made of a material other than a sponge sheet, such as a woven fabric or knitted fabric sheet.

[0045] In the case of a buffer sheet 13 having a constant thickness such as a sponge sheet, the peripheral portion may be gradually thinner toward the edge. [Explanation of symbols]
