Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, from the viewpoint of cost reduction, it is conceivable to change the molded product made of synthetic resin to a product made of carpet material.

[0006] However, when manufacturing a product consisting of the three cover parts described above by bending the carpet material, the restorative force of the carpet material causes the lower ends of the front cover and side cover parts to displace outward, making it difficult to conform to the shape of the seat base part described above.

[0007] The present invention aims to provide an interior vehicle component that can conform to the shape of a seat base, where the front surface of the base and one of the left or right side surfaces of the base are inclined downwards and inwards. [Means for solving the problem]

[0008] The vehicle interior part of the present invention as described in claim 1 is a vehicle interior part that is placed over a seat base formed in the vehicle floor panel on the lower side of the seat cushion from above, and functions as a cover for a service hole formed through the seat base, comprising: an upper cover part made of carpet material; a front cover part made of carpet material, the upper end of which is sewn to the front end of the upper cover part; and a left or right side cover part made of carpet material, the upper end of which is sewn to one of the left or right ends of the upper cover part and the front end of which is sewn to one of the left or right ends of the front cover part, wherein at least one of the front cover part and the side cover part has an acute angle between the upper edge and the vertical edge that is sewn, and a shrink portion is formed at the lower end of at least one of the front cover part and the side cover part by sewing a thread along the longitudinal direction of the lower edge so that the lower end shrinks in the longitudinal direction of the lower edge.

[0009] According to the above configuration, at least one of the front cover portion and the side cover portion has an acute angle between its upper edge and the edge of the longitudinal edge that is sewn together. As a result, it is possible to make the angle between the inner surface (bottom surface) of the upper cover portion and the inner surface of the front cover portion, and the angle between the inner surface (bottom surface) of the upper cover portion and the inner surface of one of the left or right side cover portions less than 90°. Furthermore, at least one of the lower ends of the front cover portion and the side cover portion has a contracted portion formed by sewing thread along the longitudinal direction of the lower edge so that the lower end contracts in the longitudinal direction of the lower edge. As a result, the lower end of at least one of these portions is subjected to a force in the direction of contraction, and outward displacement is suppressed.

[0010] The vehicle interior part of the present invention as described in claim 2 is the vehicle interior part of the present invention as described in claim 1, which is placed over the seat base portion having a convex curved ridge at the boundary between the top surface of the base portion and one of the left or right side portions of the base portion, wherein one of the left or right edges of the upper cover portion is formed in a convex curved shape to correspond to the convex curved ridge of the seat base portion, the upper end of the side cover portion is sewn to the convex curved edge side of the upper cover portion, and the shrink portion is formed at the lower end of the side cover portion.

[0011] According to the above configuration, the vehicle interior part is placed over the seat base, which has a convex curved ridge at the boundary between the top surface of the base and one of the left or right side surfaces of the base, from above. One of the left or right edges of the upper cover is formed in a convex curved shape to correspond to the aforementioned convex curved ridge of the seat base, and the upper end of the side cover is sewn to the convex curved edge of the upper cover, so that the side cover is positioned in a convex curved shape when viewed from above. A shrinkage section is formed at the lower end of the side cover by sewing thread to it, so that the lower end of the side cover is subjected to a force in the direction of narrowing, and outward deformation that would bring the curved shape closer to a straight line is suppressed. [Effects of the Invention]

[0012] As described above, the vehicle interior component of the present invention has the excellent effect of allowing the front portion of the base and one of the left or right side portions of the base to conform to the shape of the seat base portion, which is inclined downwards and inwards towards the base. [Brief explanation of the drawing]

[0013] [Figure 1] This is a perspective view showing the arrangement of interior components in a vehicle according to one embodiment of the present invention. [Figure 2] Figure 1 is a perspective view showing a single interior component of a vehicle. [Figure 3] Figure 1 is a plan view showing the three interior components of the vehicle in their pre-sewing state. [Modes for carrying out the invention]

[0014] Vehicle interior components relating to one embodiment of the present invention will be explained using Figures 1 to 3.

[0015] (Configuration of the embodiment) Figure 1 shows a perspective view of the arrangement of the vehicle interior components according to this embodiment. In Figure 1, arrow FR indicates the front side of the vehicle, arrow UP indicates the upper side of the vehicle, and arrow W indicates the vehicle width direction (left-right direction of the vehicle).

[0016] As shown in Figure 1, the vehicle interior component 30 according to this embodiment is placed over the seat base portion 20 formed in the vehicle body floor panel 12 on the lower side of the seat cushion 10 of the vehicle seat, and also functions as a cover for the service hole 22H formed through the seat base portion 20. In Figure 1, for the sake of clarity, only the outer shape of the seat cushion 10 in the view in Figure 1 is simplified and shown with a dashed line, and parts of the vehicle interior component 30 and the seat base portion 20 are shown as if the seat cushion 10 were transparent.

[0017] The vehicle in which the interior components 30 shown in Figure 1 are installed is a light truck (broadly speaking, a cab-over type vehicle). The seat cushion 10 is a component that supports the buttocks and thighs of the seated occupant. A seat back (not shown) that supports the back of the seated occupant is positioned at the rear end of the seat cushion 10. In addition, the seat cushion 10 in this embodiment can be raised to an upright position by flipping its front end diagonally upward and rearward of the seat.

[0018] The seat base portion 20 is formed as part of the vehicle body floor panel 12 and is convex upward relative to the general floor portion 14 of the vehicle body floor panel 12. The seat base portion 20 comprises a top plate portion 22 that constitutes its apex, a front wall portion 24 extending downward from the front end of the top plate portion 22 toward the vehicle, and a side wall portion 26 extending downward from one end of the top plate portion 22 (the left side in this embodiment). The angle between the inner surface (bottom surface) of the top plate portion 22 and the inner surface (rear surface) of the front wall portion 24, and the angle between the inner surface (bottom surface) of the top plate portion 22 and the inner surface (inner side surface) of one of the left or right side wall portions 26 are all less than 90°. That is, the front surface (outer surface) of the front wall portion 24, which is the front base front portion 24A, and the outer side surface of one of the left or right side wall portions 26A, which is the side base side portion 26A, are inclined downward toward the inside of the base. For example, the vertical dimension of the side wall portion 26 is set to be smaller than the vertical dimension of the front wall portion 24. A shelf-like portion 28 is formed from the lower end of the side wall portion 26, extending to the left side of the vehicle.

[0019] The front end of the top plate portion 22, excluding the right-hand end of the vehicle, and the front wall portion 24 are slightly curved, sloping towards the rear of the vehicle on the left side, while the left-hand end of the top plate portion 22 and the side wall portion 26 are curved to bulge outwards to the left of the vehicle. Specifically, the boundary between the top surface portion 22A of the base of the top plate portion 22 and the front base portion 24A of the front wall portion 24 is a gently convex curved ridge line L1, and the boundary between the top surface portion 22A of the base of the top plate portion 22 and the side base portion 26A of one of the left or right side wall portions 26 is a convex curved ridge line L2. The rear end of ridge line L2 is located slightly to the left of the vehicle than the front end of ridge line L2.

[0020] In addition, a service hole 22H is formed to penetrate the top plate portion 22. A battery (not shown) or the like is mounted on the lower side of the top plate portion 22 with respect to the vehicle. That is, when the seat cushion 10 is lifted up and the vehicle interior part 30 is removed, it becomes possible to access the battery or the like from the service hole 22H.

[0021] In FIG. 2, the vehicle interior part 30 alone is shown in a perspective view. The front-rear direction of the vehicle interior part 30 is the same as the vehicle front-rear direction, the up-down direction of the vehicle interior part 30 is the same as the vehicle up-down direction, and the left-right direction of the vehicle interior part 30 is the same as the vehicle width direction (vehicle left-right direction). For convenience, arrows FR, arrow UP, and arrow W are shown in the drawing of FIG. 2.

[0022] The vehicle interior part 30 includes an upper cover portion 32, a front cover portion 34 whose upper end is sewn to the front end portion of the upper cover portion 32, and a side cover portion 36 on one side (left or right) of the upper cover portion 32 whose upper end is sewn to one end portion of the upper cover portion 32 and whose front end is sewn to one end portion of the front cover portion 34 on one side (left or right). The upper cover portion 32, the front cover portion 34, and the side cover portion 36 are all made of a carpet material.

[0023] As shown in FIG. 1, the upper cover portion 32 of the vehicle interior part 30 is formed in a shape corresponding to the top plate portion 22 of the seat pedestal portion 20, and the edge 32S on one side (the side where the upper end portion of the side cover portion 36 is sewn) of the upper cover portion 32 is formed in a convex curved shape so as to correspond to the convex curved ridge line L2 of the seat pedestal portion 20. The upper cover portion 32 is disposed on the top plate portion 22 and closes the service hole 22H. The front cover portion 34 of the vehicle interior part 30 is formed in a shape corresponding to the front wall portion 24 of the seat pedestal portion 20 and is disposed along the front wall portion 24. The side cover portion 36 of the vehicle interior part 30 is formed in a shape corresponding to the side wall portion 26 of the seat pedestal portion 20 and is disposed along the side wall portion 26.

[0024] Figure 3 shows a plan view of the three pieces: the upper cover portion 32, the front cover portion 34, and the side cover portion 36, before sewing. The dashed line 32A, shown along the front end (lower end in the figure) of the upper cover portion 32, indicates the sewing position where it will be sewn to the front cover portion 34, and the dashed line 32B, shown along one of the left or right ends (the right end in the figure) of the upper cover portion 32, indicates the sewing position where it will be sewn to the side cover portion 36. Similarly, the dashed line 34A, shown along the upper end of the front cover portion 34, indicates the sewing position where it will be sewn to the upper cover portion 32, and the dashed line 34B, shown along the upper part of one of the left or right ends (the right end in the figure) of the front cover portion 34, indicates the sewing position where it will be sewn to the side cover portion 36. Furthermore, the dashed line 36A, shown along the upper end (left end in the figure) of the side cover portion 36, indicates the sewing position where it is sewn to the upper cover portion 32, and the dashed line 36B, shown along the front end (lower end in the figure) of the side cover portion 36, indicates the sewing position where it is sewn to the front cover portion 34. The angle between the line of the upper end (left end in the figure) and the line of the front end (lower end in the figure) of the side cover portion 36 is acute. In Figure 3, sewing positions 32A, 32B, 34A, 34B, 36A, and 36B are shown as dashed lines (discontinuous lines) for the sake of clarity, but it goes without saying that the sewing is done continuously.

[0025] The seam allowance of the front end (lower end in the diagram) of the upper cover portion 32 and the seam allowance of the upper end of the front cover portion 34 are overlapped with right sides facing each other and sewn together at sewing positions 32A and 34A. The seam allowance of one of the left or right ends of the upper cover portion 32 (the right end in the diagram) and the seam allowance of the upper end (left end in the diagram) of the side cover portion 36 are overlapped with right sides facing each other and sewn together at sewing positions 32B and 36A. The seam allowance of one of the left or right ends of the front cover portion 34 (the right end in the diagram) and the seam allowance of the front end (lower end in the diagram) of the side cover portion 36 are overlapped with right sides facing each other and sewn together at sewing positions 34B and 36B. In addition, small V-shaped notches are appropriately formed in each seam allowance, cut inward in the direction of the seam allowance width.

[0026] As shown in Figure 2, the side cover portion 36 has an acute angle formed by the upper edge 36X and the front vertical edge 36Y (the edge of the vertical edge that is sewn). At the lower end portion 36U of the side cover portion 36, a shrinkage portion 36S is formed by sewing thread 40 (shown as a dashed line in the figure) along the longitudinal direction of the lower edge 36Z so that the lower end portion 36U shrinks in the longitudinal direction of the lower edge 36Z. The total amount of shrinkage of the shrinkage portion 36S is set appropriately based on the material of the side cover portion 36, the angle of the angle formed by the upper edge 36X and the front vertical edge 36Y, and the inclination of the base side portion 26A of the seat base portion 20 shown in Figure 1. Note that in Figures 1 and 2, the shrinkage portion 36S is simplified and shown as a tuck for easier understanding.

[0027] In Figure 3, a dashed line 36C is shown at the lower end 36U of the side cover portion 36 where the thread 40 (see Figure 2) is sewn. In Figure 3, the sewing position of the thread 40 (see Figure 2) is shown with a dashed line (a discontinuous line) for convenience, but it goes without saying that the sewing using the thread 40 (see Figure 2) is done continuously. In the state shown in Figure 3, the thread 40 (see Figure 2) has not been sewn, so the shrinkage portion 36S (see Figure 2) has not been formed.

[0028] (Effects and mechanisms of the embodiment) Next, the operation and effects of this embodiment will be described.

[0029] In this embodiment, as shown in Figure 2, the side cover portion 36 has an acute angle formed by the upper edge 36X and the front vertical edge 36Y. Therefore, it is possible to make the angle formed by the inner surface (bottom surface) of the upper cover portion 32 and the inner surface of the front cover portion 34, and the angle formed by the inner surface (bottom surface) of the upper cover portion 32 and the inner surface of one of the left or right side cover portions 36, all less than 90°. Furthermore, at the lower end portion 36U of the side cover portion 36 shown in Figure 1, a contracted portion 36S is formed by sewing thread 40 along the longitudinal direction of the lower edge 36Z so that the lower end portion 36U contracts in the longitudinal direction of the lower edge 36Z. Therefore, the lower end portion 36U of the side cover portion 36 is subjected to a force in the direction of contraction, and outward displacement is suppressed.

[0030] To elaborate, when the contracted portion 36S is formed, the lower end portion 36U of the side cover portion 36 is contracted in the longitudinal direction of its lower edge 36Z. As a result, a force acts in a direction that tries to reduce the angle between the upper edge 36X and the front vertical edge 36Y. Consequently, the contracted portion 36S tends to displace inward, and the lower end portion 36U of the side cover portion 36 tends to curl inward. Therefore, the outward displacement of the lower end portion 36U of the side cover portion 36 is suppressed.

[0031] To explain further, the vehicle interior part 30 of this embodiment, shown in Figure 1, is placed over the seat base 20, which has a convex curved ridge line L2 at the boundary between the top surface 22A of the base and one of the left or right side surfaces 26A of the base, from above. One of the left or right edges 32S of the upper cover part 32 is formed in a convex curved shape to correspond to the convex curved ridge line L2 of the seat base part 20, and the upper end of the side cover part 36 is sewn to the convex curved edge 32S side of the upper cover part 32, so that the side cover part 36 is positioned in a convex curved shape when viewed from above. Furthermore, as mentioned above, thread 40 is sewn to the lower end 36U of the side cover part 36 to form a contracted portion 36S, so that the lower end 36U of the side cover part 36 is subjected to a force in the direction of narrowing, and outward deformation that would bring the curved shape closer to a straight line is suppressed.

[0032] As described above, the vehicle interior part 30 of this embodiment makes it possible to conform the shape of the seat base 20, inclined downwards and inwards towards the base, to the front base portion 24A and one of the left or right side base portions 26A.

[0033] (Supplementary explanation of the embodiment) As a variation of the above embodiment, the front cover portion (34) may also be configured such that the angle between the upper edge and the vertical edge on the side that is sewn to the side cover portion (36) is acute. In such a configuration, the angle between the upper edge (36X) of the side cover portion (36) and the front vertical edge (36Y (the vertical edge on the side that is sewn)) may be either acute or right angle.

[0034] Furthermore, as a modification of the above embodiment, a shrinkage portion can be formed at the lower end of the front cover portion (34) by sewing thread along the longitudinal direction of the lower edge so that the lower end shrinks in the longitudinal direction of the lower edge. In such a configuration, a shrinkage portion (36S) can also be formed at the lower end (36U) of the side cover portion (36), or a shrinkage portion (36S) can not be formed at the lower end (36U) of the side cover portion (36).

[0035] Furthermore, as a variation of the above embodiment, for example, the seat base portion may have a straight ridge at the boundary between the top surface of the base and one of the left or right side surfaces of the base, and the present invention may be applied to a vehicle interior part that is placed over such a seat base portion from above. Furthermore, as another variation, for example, the seat base portion may have a straight ridge at the boundary between the top surface of the base and the front surface of the base, and the present invention may be applied to a vehicle interior part that is placed over such a seat base portion from above.

[0036] Furthermore, the above embodiments and the various modifications described above can be combined as appropriate.

[0037] Although an example of the present invention has been described above, the present invention is not limited to the above, and it is of course possible to implement it in various modified forms without departing from its spirit. [Explanation of Symbols]
