They are connected by a connecting portion 30 or the like. Then, the plurality of external portions 21 and 22 are moved in the frame portions 4F and 6F shown in FIG. 2 so as to be sparse or dense while changing their relative positions. By doing so, it is possible to displace the seating surface portions 10 from an arrangement state in which a planar design surface is formed to an arrangement state in which a curved design surface is formed. In this manner, in this embodiment, the external portions 21 and 22 are arranged in a dense or sparse manner while changing their relative positional relationship, so that they are arranged along a desired shape (planar shape or curved shape). . Therefore, below, the manner in which the shape of the upper seat surface portion 12 is changed will be specifically explained using the upper seat surface portion 12 as an example.

Here, in the following description, with reference to FIGS. 10 and 11, it is assumed that the right arm section 63 of the upper frame section 6F is bent toward the front side, which is the seating side. At this time, in the upper seating surface portion 12, the plurality of external portions 21 and 22 are arranged in a curved shape while gradually rising toward the front side by receiving the force of the right movable portion 63b (movable mechanism) of the right arm portion 63. . In the upper seating surface portion 12, as shown in FIGS. 3 and 12, each first outer shape portion 21 and each second outer shape portion 22 move individually to form a desired curved surface shape (curvature, etc.). Their relative positions can be changed flexibly.

For example, the adjacent first external portion 21 and second external portion 22 slide in the axial length direction (direction of arrow A1) of the connecting portion 30 and gradually move apart, as shown in FIG. In this way, the plurality of external parts 21 and 22 can be displaced from a densely arranged state along the original planar shape shown in FIG. 3 to a sparsely arranged state along the curved shape shown in FIG. . Further, the upper seat surface portion 12 on the side portion 12b of the upper top plate shown in FIG. 11 gradually curves forward as it goes from left to right. At this time, as shown in FIG. 7, the first external portion 21 and the second external portion 22 are connected to each other by the tilting of the connecting portion 30 with respect to the first external portion 21 (tilting in the direction of arrow A3). Their relative positions can be changed in the front-back direction. Furthermore, the upper seating surface portion 12 shown in FIG. 11 may gradually curve forward as it goes from top to bottom (or from bottom to top). In such a case, the first external portion 21 and the second external portion 22 prevent the second plate portion 320 from rotating around the axis of the rotating shaft 313 (in the direction of arrow A2), as shown in FIG. You can change the degree of inclination between them. In this manner, in this embodiment, the curved surface shape (curvature) of the upper seating surface portion 12 can be changed finely by moving each of the external portions 21 and 22 individually to take an appropriate relative positional relationship. When the occupant leaves the vehicle seat 2, the shape of the upper seating surface portion 12 may be maintained as it is, or it may be returned to its original state. That is, by returning the right movable portion 63b to its original state as shown in FIG. 10, the plurality of external portions 21 and 22 can be returned to the planar arrangement state shown in FIG. 3.

In this way, by changing the shape of the seating surface 10 shown in FIG. 1 according to the physical characteristics of the occupant (body shape, size of physique, posture, etc.), the seating surface 10 can be made to fit the seated occupant. It becomes possible. Further, referring to FIGS. 2 and 11, the lower frame portion 4F and the upper frame portion 6F have respective tube materials TM1 and TM2 as artificial muscles. Each of these tube materials TM1 and TM2 is difficult to deform in the direction of contraction (horizontal direction), but easily deformed in a direction perpendicular to the direction of contraction (for example, front-rear direction or up-down direction). Therefore, in this embodiment, each of the tube materials TM1 and TM2 shown in FIG. 11 is able to support the outer seat surface portion 12 and the like while appropriately flexing and deforming, and it is possible to make the outer seat surface portion 12 and the like fit the occupant better. can.

In the vehicle seat 2, as shown in FIGS. 1 and 3, a seating surface section 10, which serves as the design surface of the seat cushion section 4 and the seat back section 6, is integrally formed with a plurality of external sections 21 and 22. . Further, in the seat cushion part 4, the lower top plate main part 11a and each lower top plate side part 11b, 11c are integrally formed, and in the seat back part 6, the upper top plate main part 12a and each upper top plate side part 12b, 12c are integrally formed. are integrally formed. Therefore, in this embodiment, the shape of the seating surface section 10 shown in FIG. The structure is conducive to this. For example, in the case of a small passenger, a movable mechanism (not shown) that moves in the width direction of the seat may be used to closely arrange the external portions 21 and 22 of the seating surface 10 as shown in FIG. Can be made smaller. On the other hand, in the case of a large-sized occupant, the outer portions 21 and 22 of the seating surface portion 10 can be arranged sparsely to increase the area thereof, as shown in FIG. Furthermore, in the vehicle seat 2 shown in FIG. 1, when traveling on a curve, etc., either the left or right top plate side portions 11b, 12b (11c, 12c) are made to protrude toward the seating side, or each top plate side portion is partially It is also possible to make a target stand out and call attention to it (call for attention).

As described above, in this embodiment, the plurality of external parts 21 and 22 forming the seating surface part 10 (design surface) are connected to each other by the connecting part 30 and the like so that their relative positions can be changed. In this embodiment, the external shapes 21 and 22 are arranged densely or sparsely while changing their relative positional relationship, and are arranged along a desired shape (planar shape or curved shape), thereby improving the design. It becomes possible to change the shape of the surface more freely. Therefore, according to this embodiment, the shape of the seating surface portion 10, which serves as a design surface forming the external appearance, can be changed more freely.

Furthermore, in this embodiment, by inserting the connecting part 30 etc. that are tiltably attached to the first external part 21 into the second external part 22 in a state where the relative position can be changed, the design surface can be freely changed. is possible. By arranging the plurality of connecting portions 30 to 32 in a crosswise manner within the second external portion 22, the strength of the second external portion 22 is improved. In addition, in this embodiment, considering that the vehicle interior component is used as a vehicle seat 2, the design surface of each top plate main portion 11a (12a) and each top plate side portion 11b, 11c (12b, 12c) is The seating surface portion 10 is integrally formed with a plurality of external portions 21 and 22. Therefore, the shape of the seating surface portion 10 can be freely changed at appropriate positions on each top plate main portion 11a (12a) and each top plate side portion 11b, 11c (12b, 12c). Furthermore, in this embodiment, the seating surface section 10, which serves as the design surface of the seat cushion section 4 and the seat back section 6, is integrally formed with a plurality of external sections 21 and 22. Therefore, the shape of the seating surface section 10 can be freely changed at appropriate positions of the seat cushion section 4 and the seat back section 6.

[Modification 1]
Here, the configuration of the seating surface portion (design surface) may take various configurations in addition to the above-mentioned configuration. For example, in the seating surface portion 10X of Modification 1 shown in FIG. 13, the first outer portion 21X and the second outer portion 22X are arranged alternately in a generally square grid pattern and connected by corresponding connecting portions 30X. Each of the first external portions 21X and the second external portions 22X is a quadrangular prism-shaped hollow member facing in the front-rear direction, and has a generally regular square shape in plan view when viewed from the design surface side. In this modification, when the second external portion 22X is viewed from the design surface side, the reinforcing column portions 322X of the four connecting portions 30X are arranged in a cross shape to form a cross inside the second external portion 22X. (See the second external portion indicated by the two-dot broken line in FIG. 13). These four reinforcing column parts 322X are formed to have different positions in the height direction (front-back direction) of the second external part 22X, and are arranged so that they overlap from the front and back approximately at the center (X) of the second external part 22X. arranged and intersecting. In this way, in this modification, by using the four reinforcing column parts 322X as reinforcing materials, the strength of the second external shape part 22X can be ensured even more reliably.

[Modification 2]
Further, the seating surface portion 10Y of Modification Example 2 shown in FIG. 14 has roughly the same basic configuration as the seating surface portion of Modification Example 1, but the first outer shape portion 21Y and the second outer shape portion 22Y are approximately cylindrical. It has a circular shape when viewed from the seating surface side. Also in this modification, when the second external portion 22Y is viewed from the design surface side, the reinforcing column portions 322Y of the four connecting portions 30Y cross each other to form a cross inside the second external portion 22Y. Because of this arrangement, the strength of the second external portion 22Y can be ensured more reliably (see the second external portion indicated by the two-dot broken line in FIG. 14). In this modification, each of the external portions 21Y and 22Y is formed into a cylindrical shape, but it may be an elliptical cylinder, a sphere, or a hemisphere, and by combining these, a unique design and feel can be expressed.

[Modification 3]
Further, in the seating surface portion 10Z of Modification 3 shown in FIG. 15, the first external portion 21Z and the second external portion 22Z each have a triangular shape when viewed from the seating surface side, and are arranged alternately in a roughly triangular lattice shape. has been done. Furthermore, since the reinforcing column parts 322Z of the three connecting parts 30Z are arranged in an intersecting manner inside the second external part 22Z, the strength of the second external part 22Z can be ensured (in FIG. (See the second outline shown in dotted lines). Since each of the external portions 21Z and 22Z has a triangular shape with the minimum sides that do not easily collapse, the structure has even better strength.

[Modification 4]
Moreover, in the modification 4 shown in FIG. 16, a connecting portion 30A that connects the first external portion 21 and the second external portion 22 is different from the example. The connecting portion 30A of this modification has a portion corresponding to the second plate portion (slide plate portion 321, reinforcing column portion 322, tip surface 323) as in the first embodiment, but the first plate portion Instead, it integrally includes a ball joint portion 310A. This ball joint portion 310A is a generally spherical portion, and is rotatably inserted into the first external portion 21. In this modification, the first outer shape part 21 and the second outer shape part 22 are connected in a state in which the positions can be displaced along the curved surface of the ball joint part 310A of the connecting part 30A, so that the relative positions of each other can be further controlled. It can be changed flexibly.

The vehicle seat (vehicle interior component) of this embodiment is not limited to the embodiment described above, and may take various other embodiments. In this embodiment, the configurations (shapes, dimensions, placement positions, number of placements, etc.) of the external portions 21, 22, etc. and the connecting portion 30, etc. are illustrated, but this is not intended to limit the configuration of each part. For example, it is also possible to connect the first plate part and the second plate part of the connecting part via a ball joint or a universal joint. Further, when a plurality of connecting portions are inserted through the second external shape portion, all or part of the plurality of connecting portions can be arranged in an intersecting manner, or may not be arranged in an intersecting manner. Further, as the arrangement state of each external portion, various lattice states can be adopted in addition to a hexagonal lattice, a square lattice, and a triangular lattice, and it is also possible to arrange them randomly. Further, the shape and dimensions of each external portion can be changed as appropriate, and may have mutually different shapes and dimensions (irregular shapes). Further, the plurality of external parts can be made into polygonal shapes that can be filled in a plane, but it is not necessary to arrange them in a filling manner. The configurations of the external shape and connecting portion of the embodiment and each modification can be used in combination as appropriate.

Furthermore, in this embodiment, the seating surfaces of the seat cushion section 4 and the seat back section 6 are integrally formed, but the underwear seating surface section of the seat cushion section and the upper seating surface section of the seat back section may also be formed separately. . Further, the seating surface portion can be formed separately from the top plate main portion and each top plate side portion. Further, in this embodiment, an example in which each frame portion is used as a movable mechanism has been described, but this is not intended to limit the configuration of the movable mechanism. For example, various actuators and airbags can be used as the movable mechanism, and wire rods or surface materials that contract by electrical or thermal stimulation can be used as the artificial muscles. Various movable mechanisms can be installed to change the external shape of the entire or part of the seating surface, or at least a part of it can be moved to provide an attention-calling function or a massage function.

Further, in this embodiment, the vehicle seat 2 is illustrated as an example of a vehicle interior component, but the configuration of this embodiment can be applied to various vehicle interior components. In addition to vehicle seats, examples of this type of vehicle interior parts include various parts such as door parts, instrument panels, ceiling parts, and consoles. The present invention can be suitably applied to vehicle interior parts installed in vehicles. By changing the external shape of the vehicle interior components to suit the occupant, it is possible to create a vehicle interior environment suitable for a specific occupant. Furthermore, in a vehicle seat, the configuration of this embodiment can be applied to the seat cushion portion, the seat back portion, and other portions that constitute the design surfaces of various seat constituent members such as an armrest. Furthermore, even when the length of the front and back of the seat cushion section is variable, or when the length of the seat back section is variable (for example, when the headrest section can be raised and lowered), this embodiment A surface portion can be suitably used.
