[0018] A vehicle (vehicle) 10 employing a vehicle interior structure 1 according to one embodiment will be described with reference to Figures 1 to 12. As shown in Figure 1, the vehicle 10 according to this embodiment has a box-shaped body 12 that is relatively large in the longitudinal and vertical directions, and is capable of transporting a plurality of people in the cabin, which is the interior space of the body 12. A plurality of seats 50 are provided in the cabin, and some of the seats 50 are arranged sideways in the direction of travel along the inside of a side wall portion 11 of the vehicle 10 that extends in the longitudinal direction.

[0019] The side wall portion 11 of the vehicle 10 is configured to include a body 12 that forms the exterior shape of the vehicle 10, and side wall trims 30, 80 that cover part of the body 12 from the inside of the vehicle cabin. The body 12 is equipped with multiple long support members that extend in the front-to-rear direction. As shown in Figure 3, the support member arranged on the upper side is an upper support member 13, which has a flattened rectangular tube shape and is arranged so that the opposing wide surfaces face the inside and outside of the vehicle.

[0020] Three vertical support members 20 (three in this embodiment) extending in the vertical direction are fixed at equal intervals to the surface of the upper support member 13 facing the interior of the vehicle (see FIGS. 2 and 3). The vertical support members 20 are flattened rectangular tubular shapes, and are integrated with the upper support member 13 with their opposing wide surfaces facing the interior and exterior of the vehicle. As shown in FIG. 7, an upper cutout 21 is provided in the vertical support member 20 at a position corresponding to the upper support member 13, cut from the exterior of the vehicle toward the interior of the vehicle. The upper support member 13 is fitted into this upper cutout 21 from the exterior of the vehicle, thereby positioning and assembling the upper support member 13 and the vertical support member 20. The upper end of the vertical support member 20 protrudes slightly upward from the upper end of the upper support member 13.

[0021] A central notch 22 cut from the inside of the vehicle cabin toward the outside of the vehicle cabin is provided in the wall surface of the vertical support member 20, which is approximately in the center in the up-down direction, and faces the inside of the vehicle cabin (see Figure 3), and a central support member 25 extending in the front-to-rear direction is assembled by being fitted into this central notch 22. The central support member 25 has a flattened rectangular tube shape, and is assembled to the vertical support member 20 with the opposing wide surfaces facing the inside and outside of the vehicle.

[0022] Furthermore, below the central cutout 22 of the vertical support member 20, a lower cutout 23 is provided in the wall surface facing the inside of the vehicle cabin, cut from the inside of the vehicle cabin toward the outside of the vehicle cabin, and two lower support members 28 extending in the front-to-rear direction are assembled side by side in the vertical direction by being fitted into this lower cutout 23. The two lower support members 28 have a flattened rectangular cylindrical shape and are assembled to the vertical support member 20 with their opposing wide surfaces facing the inside and outside of the vehicle.

[0023] The upper support member 13 is covered from the inside of the vehicle compartment by a sidewall trim 30, which will be described later, and the lower support member 28 is covered from the inside of the vehicle compartment by a lower sidewall trim 80. The upper support member 13 and the lower support member 28 have lengths that protrude in the vehicle longitudinal direction from both ends of a plurality of seats 50, which will be described later and are arranged side by side in the vehicle longitudinal direction. On the other hand, the central support member 25 has a length that is within the range of the width of the plurality of seats 50 arranged side by side (see FIG. 2).

[0024] 2 is a perspective view of the seat 50, which is disposed sideways in the direction of travel and attached to the three support members 13, 25, and 28. In this embodiment, three seats 50 are arranged in a line in the front-to-rear direction. Each seat 50 includes a seat cushion 51 and a seat back 60.

[0025] The seating surface 51 is attached to the central support member 25 via seating surface attachment portions 52 provided at both ends in the width direction (front-rear direction of the vehicle). In addition, a seating surface support portion 53 attached to the lower support member 28 is provided below the seating surface 51, and the seating surface 51 is supported by this seating surface support portion 53 from the underside.

[0026] On the other hand, the seat back 60 is attached to the upper support member 13 and the central support member 25. The seat back 60 has both widthwise ends that gently curve toward the inside of the vehicle cabin so as to fit the back of the occupant when seated in the seat 50, and the upper portion is shaped like a plate that is slightly warped toward the outside of the vehicle cabin.

[0027] As shown in Figure 4, the seat back 60 has a first locking portion 61 at the upper part of the surface facing outside the vehicle cabin (referred to as the back surface 60A) and a second locking portion 73 at the lower end part, and is attached to the body 12 by the first locking portion 61 locking to the upper support member 13 and the second locking portion 73 locking to the central support member 25.

[0028] 4 and 5, the first engaging portion 61 includes nine plate-shaped upright walls 63 that rise up from the rear surface 60A of the seat back 60 toward the outside of the vehicle cabin in a vertical direction. These upright walls 63 are arranged in groups of three in the width direction of the seat back 60 (the front-rear direction of the vehicle). Each upright wall 63 has an upper portion that is a first protruding portion 64 that protrudes most from the rear surface 60A, and the protruding dimension on the lower side gradually decreases, forming a three-step staircase shape in a side view (see FIG. 6). A slit 66 extending a predetermined distance in the vertical direction is provided at the boundary between the first protruding portion 64 and a second protruding portion 65 that is connected to the lower end of the first protruding portion 64. The opening of the slit 66 has a diameter that increases downward, and this increased diameter portion functions as a guide that guides the bridge portion 16 (described later) into the slit 66.

[0029] Three standing walls 63 having such a shape are grouped together to form three standing wall groups 62. The three standing walls 63 of one standing wall group 62 are connected by a plurality of horizontal walls 67. Specifically, the three standing walls 63 of one standing wall group 62 are connected by a first horizontal wall 67A that continues from the back surface 60A of the seat back 60 and connects upper portions of the first protrusions 64 of the three standing walls 63, a second horizontal wall 67B that connects lower ends of the three first protrusions 64, and a third horizontal wall 67C that connects groove walls of the three slits 66 that are on the outer side of the vehicle cabin.

[0030] Furthermore, each of the three standing wall groups 62 is connected to the adjacent standing wall groups 62 by a connecting rib 68. The connecting ribs 68 are two ribs that protrude from the rear surface 60A of the seat back 60 and extend in the width direction of the seat 50, and are provided at positions that connect the first protrusions 64 that are arranged opposite each other in the adjacent standing wall groups 62.

[0031] In addition, a portion of the connecting rib 68 is connected to a base portion 69 arranged parallel to the back surface 60A of the seat back 60, and the base portion 69 is provided with a cylindrical positioning protrusion 70 that protrudes toward the outside of the vehicle cabin (see Figure 5).

[0032] Furthermore, reinforcing ribs 71 rising from the rear surface 60A of the seat back 60 are provided on both ends of the three standing wall groups 62 in the width direction of the seat back 60.

[0033] The protruding dimensions of the nine standing walls 63 are set so that the tip surfaces of the nine standing walls 63 in the protruding direction from the rear surface 60A of the seat back 60 are aligned on the same plane (see FIG. 12).

[0034] On the other hand, as shown in Fig. 4, the second engaging portion 73 is provided in the center in the width direction of the seat back 60. The second engaging portion 73 is tubular and has a pillar portion 74 rising from the rear surface 60A of the seat back 60 and a hole 75 penetrating in the interior and exterior directions of the vehicle cabin. A peripheral wall 76 rising from the rear surface 60A is provided around the pillar portion 74 so as to surround the pillar portion 74, and the peripheral wall 76 and the pillar portion 74 are connected by a plurality of connecting walls 77. In addition, the outer surface of the peripheral wall 76 is provided with a plurality of reinforcing ribs 78 that rise from the rear surface 60A of the seat back 60 and extend in the width direction.

[0035] 7, the upper support member 13 is provided with a first locked portion 14 at a position corresponding to the first locking portion 61 of the seat back 60, for collectively locking the first locking portion 61, i.e., the three standing wall groups 62. The first locked portion 14 is formed in a flat, generally U-shape by bending both ends of a long, generally band-shaped plate material in the same direction (toward the outside of the vehicle compartment), and protrudes in a gate-like shape from the lower end of the interior surface of the upper support member 13 toward the inside of the vehicle compartment. Hereinafter, if both ends of the first locked portion 14 are referred to as leg portions 15 and the portion connecting the two leg portions 15 is referred to as a bridging portion 16, the bridging portion 16 of the first locked portion 14 is disposed in a direction such that its plate surface faces the interior and exterior of the vehicle compartment. A notch 17 is formed in the bridge portion 16 of the first engaging portion 14 near one end (to the left in Figure 7) by cutting out from the upper end to allow the positioning protrusion 70 of the seat back 60 to escape.

[0036] Furthermore, a second locked portion 26 is provided on the central support member 25 at a position corresponding to the second locking portion 73 of the seat back 60, for fastening a bolt that is passed through the hole 75 of the second locking portion 73 (see FIG. 2). The second locked portion 26 is formed in a generally U-shape by bending both ends of a generally strip-shaped plate material in the same direction (toward the outside of the vehicle compartment), and protrudes in a gate-like shape from the interior surface of the central support member 25 toward the inside of the vehicle compartment. The bridging portion 27 of the second locked portion 26 is arranged in a direction such that the plate surface faces the interior and exterior of the vehicle compartment.

[0037] The above-mentioned vertical support member 20 is provided at a position where it is located at the center of the first locked portion 14 and the second locked portion 26 in the width direction.

[0038] The upper side of the seat back 60 is attached to the upper support member 13 by collectively engaging the above-mentioned first locking portions 61 (three standing wall groups 62) with the first locked portions 14. In other words, the upper side of the seat back 60 is attached to the body 12 by fitting the bridging portions 16 of the first locked portions 14 into the slits 66 of the nine standing walls 63 (see FIG. 6).

[0039] Furthermore, by fastening the second locking portion 73 to the second locked portion 26, the lower end of the seat back 60 is attached to the central support member 25 (body 12).

[0040] Generally, the side walls of a vehicle are configured by covering the interior surface of the body with trim as an interior material. In this embodiment, the interior surface of the upper support member 13 is also configured to be covered with the side wall trim 30. However, as described above, when the seat back 60 is fixed to the body 12 (the upper support member 13 and the central support member 25), a gap S is formed between the seat back 60 and a main body portion 31 (described later) of the side wall trim 30 (see FIGS. 6 and 12). Such a gap S causes the engaging portion between the seat back 60 and the body 12 to be visible to passengers, resulting in an unattractive appearance and a decrease in the interior design of the vehicle. In addition, there is a problem that objects are likely to fall into the gap S.

[0041] Therefore, in this embodiment, the sidewall trim 30 covering the upper support member 13 is provided with a cover portion 40 that closes the gap S between the seat back 60 and the main body portion 31 of the sidewall trim 30. The sidewall trim 30 will be described below.

[0042] The sidewall trim 30 is an interior material that covers the upper support member 13 from the inside of the vehicle cabin, and as shown in FIG. 8, is mainly composed of a main body 31 that is U-shaped and straight and has a flat cross section. An opening 35 is provided in the main body 31 in an area corresponding to the first locked portion 14 of the upper support member 13 to expose the first locked portion 14 to the inside of the vehicle cabin. The opening is substantially rectangular in shape and has an upper edge 35A that bulges out gently upward (see FIG. 9). The width of the opening 35 is slightly wider than the width of the first locked portion 14, and the height of the widthwise center portion is set to expose the lower end of the first locked portion 14 and the upper end of the upper support member 13 (see FIG. 6). When the side wall trim 30 covers the upper support member 13 from inside the vehicle cabin, the bridging portion 16 of the first engaging portion 14 protrudes slightly toward the vehicle cabin beyond the opening edge of the opening 35 of the main body portion 31 (see also Figure 6).

[0043] In the following description, the portion of the main body 31 of the side wall trim 30 that covers the upper side of the upper support member 13 will be referred to as the ceiling wall 32, the portion that covers the lower side of the upper support member 13 as the bottom wall 33, and the portion that connects the ceiling wall 32 and the bottom wall 33 and covers the interior-facing surface of the upper support member 13 will be referred to as the front wall 34. The opening 35 described above is provided near the top of the front wall 34.

[0044] The sidewall trim 30 has a plurality of locking projections 36 that protrude from the back surface 31A of the main body 31 toward the outside of the vehicle cabin at the boundary between the ceiling wall 32 and the front wall 34 (see FIGS. 6 and 8). These locking projections 36 are intended to be locked to the upper end of the upper support member 13, thereby preventing the main body 31 of the sidewall trim 30 from bending downward or falling off the upper support member 13. In this embodiment, the locking projections 36 are provided between two adjacent openings 35 and near one end of the main body 31 (to the left in FIG. 8).

[0045] Furthermore, a U-shaped cutout 37 is provided in the ceiling wall 32 in a portion corresponding to the widthwise center of the opening 35, cutting out the cutout 37 from the outer end of the vehicle compartment toward the inner end, as shown in Fig. 9. Both sides of the cutout 37 in the widthwise direction are recessed portions 38 recessed from the upper surface of the ceiling wall 32, and a plate-shaped plate 19 can be positioned within the recessed portions 38 (see Fig. 11).

[0046] In addition, in the area of ​​the bottom wall 33 corresponding to the vertical support member 20, an escape recess 39 (see Figure 10) for escaping the vertical support member 20 is provided, cut out in a U-shape from the end outside the passenger compartment toward the inside of the passenger compartment.

[0047] Furthermore, the side wall trim 30 of this embodiment is provided with a cover portion 40 that protrudes from the opening edge of the opening 35 toward the inside of the vehicle cabin. The cover portion 40 protrudes from an upper edge portion 35A located at the top of the four opening edge portions of the opening 35 and from two side edge portions 35B located at the sides. In other words, the cover portion 40 protrudes from the opening edge of the opening 35 toward the inside of the vehicle cabin in a generally gate-like shape.

[0048] In the following description, the portion of cover portion 40 that protrudes from upper edge portion 35A of opening 35 will be referred to as upper wall 41, and the portions that protrude from two side edges 35B will be referred to as side walls 42. As shown in Figures 9 and 10, side walls 42 extend continuously from upper wall 41 to the lower end of opening 35.

[0049] The projection dimension of the cover portion 40 from the opening edge is set to a projection dimension that almost perfectly fills the gap S formed between the seat back 60 and the main body portion 31 of the side wall trim 30 when the seat back 60 is assembled in the correct position. In other words, the projection dimension of the cover portion 40 from the opening edge is set to a dimension that allows the tip of the cover portion 40 to abut against or be close to the back surface 60A of the seat back 60.

[0050] Specifically, the upper wall 41 has a shape in which the protruding dimension at the center is shorter than at both ends, and the tip is arcuate in plan view, in accordance with the curved shape of the seat back 60. The upper wall 41 also has a gently curved shape in which the center in the width direction bulges slightly upward along the upper edge 35A of the opening 35.

[0051] The side wall 42 is generally trapezoidal in side view, with a lower protruding dimension greater than an upper protruding dimension, in accordance with the inclined shape of the seat back 60 .

[0052] With the cover portion 40 shaped as described above, the locking structure between the seat back 60 and the upper support member 13 (body 12), i.e., the locking portion between the first locking portion 61 and the first locked portion 14, is covered and hidden from above and from the sides (see FIGS. 6 and 12), improving the appearance (design) between the seat back 60 and the main body portion 31 of the side wall trim 30. Furthermore, since the gap S is closed by the cover portion 40, it is possible to prevent an object from falling from above between the seat back 60 and the main body portion 31 and becoming unable to be removed.

[0053] Furthermore, the sidewall trim 30 of this embodiment is integrally provided with mounting seats 43 for attaching the sidewall trim 30 to the body 12 (upper support member 13). Two mounting seats 43 are provided for each opening 35, extending inward from the opening edge portions near both ends in the width direction of the opening 35, and the sidewall trim 30 can be attached to the upper support member 13 by overlapping the seat surface portions 44 of the mounting seats 43 with the bridging portions 16 of the first locked portions 14 of the upper support member 13 from the inside of the vehicle compartment and fastening them with bolts.

[0054] More specifically, as shown in Figures 9 and 10, the mounting seat 43 extends inward from positions of the lower edge 35C of the opening 35 adjacent to both widthwise ends. As described above, when the side wall trim 30 covers the upper support member 13 from the inside of the vehicle cabin, the bridging portion 16 of the first locked portion 14 is located slightly inside the vehicle cabin relative to the edge of the opening 35 of the main body 31 (see Figure 6). The seating surface portion 44 of the mounting seat 43 is configured to overlap this bridging portion 16 from the inside of the vehicle cabin. In other words, the seating surface portion 44 is arranged parallel to the plate surface of the bridging portion 16 at a position where it rises from the lower edge 35C to the inside of the vehicle cabin by the rising portion 45 so as to be located closer to the inside of the vehicle cabin than the lower edge 35C of the opening 35.

[0055] Furthermore, the side edge of the seat portion 44 is connected to the side wall 42 of the cover portion 40. Specifically, the seat portion 44 is connected to a horizontal connecting portion 46 that extends in an L-shape from the lower end of the cabin-side edge of the side wall 42 of the cover portion 40 toward the inside of the opening 35 and the outside of the cabin. That is, the horizontal connecting portion 46 and the seat portion 44 are connected together in a crank shape as a whole.

[0056] Furthermore, the lower end of this horizontal connecting portion 46 and the lower edge portion 35C of the opening 35 are integrally connected by a lower connecting portion 47. As shown in Figure 10, the rising portion 45 of the seat portion 44 and the lower connecting portion 47 are formed into a single continuous plate.

[0057] A through hole 48 is formed in the seat portion 44, and this through hole 48 is set to communicate with the bridge portion-side through hole 18 provided in the bridge portion 16 (see FIG. 7). This makes it possible to attach the seat portion 44 to the first locked portion 14 (bridge portion 16), and therefore the side wall trim 30 to the body 12 with a bolt, clip, or the like (see FIGS. 11 and 12).

[0058] One of the through holes 48 of each of the two mounting seats 43 provided adjacent to both ends of the opening 35 (left side in FIG. 9) is circular, and the other (right side in FIG. 9) is a horizontally long hole, which allows tolerances during mounting to be accommodated.

[0059] Next, the effects will be described. This embodiment is a vehicle interior structure 1 for a side wall portion 11 to which a seat back 60 of a seat 50 arranged in the passenger compartment of a vehicle 10 is fastened, the side wall portion 11 including an upper support member 13 (body 12) and a side wall trim 30 that covers a part of the upper support member 13 (body 12) from the inside of the passenger compartment, the upper support member 13 (body 12) including a first fastened portion 14 that fastens the seat back 60, and the side wall trim 30 including a main body portion 31 that forms the passenger compartment surface of the side wall portion 11, and a cover portion 40 that protrudes from the main body portion 31 toward a rear surface 60A of the seat back 60 and closes a gap S between the main body portion 31 and the seat back 60 from above the first fastened portion 14.

[0060] According to the above configuration, the locking portions (first locked portion 14 and first locking portion 61) for locking the seat back 60 to the body 12 are covered from above by the cover portion 40, which improves the appearance (design) of the gap S formed between the side wall portion 11 and the seat back 60. Furthermore, by closing the gap S from above with the cover portion 40, it is possible to prevent objects from falling into the gap S.

[0061] The main body 31 also has an opening 35 that exposes the first latched portion 14 to the interior of the vehicle, and the cover 40 protrudes from an upper edge 35A of the opening 35 toward the rear surface 60A of the seat back 60.

[0062] In addition, the sidewall trim 30 is provided with a mounting seat 43 for attaching the sidewall trim 30 to the body 12, and the mounting seat 43 is formed in a manner that extends from the edge of the opening 35 to the inside of the opening 35.

[0063] According to the above configuration, not only the engaging portion between the body 12 and the seat back 60 but also the portion where the side wall trim 30 is attached to the body 12 is covered from above by the cover portion 40, thereby improving the design of the interior of the vehicle.

[0064] In addition, the opening 35 is approximately rectangular, and the cover portion 40 is gate-shaped, having an upper wall 41 that protrudes from the upper edge portion 35A of the opening 35 toward the back surface 60A of the seat back 60, and side walls 42 that are connected to the upper wall 41 and protrude from the two side edge portions 35B of the opening 35 toward the back surface 60A of the seat back 60, and the mounting seat 43 is connected to the lower edge portion 35C of the opening 35 and the side walls 42.

[0065] According to the above configuration, the mounting seat 43 extending from the lower edge portion 35C of the opening 35 is connected to the side wall 42 of the cover portion 40, thereby increasing the rigidity of the mounting seat 43. Furthermore, the intrusion of foreign matter into the opening 35 can be prevented.

[0066] The opening 35 is formed in the shape of a slot that is long in the horizontal direction, and the mounting seats 43 are provided at positions adjacent to both ends of the opening 35 in the longitudinal direction.

[0067] According to the above configuration, the side wall trim 30 can be attached to the body 12 in a state where it is less likely to shift position.

[0068] In addition, the side wall trim 30 of this embodiment is attached to the inside of the vehicle cabin of the body 12 to which the seat back 60 of the seat 50 arranged in the vehicle cabin is engaged by the first engaging portion 61 and the first engaged portion 14, and together with the body 12 forms the side wall portion 11 of the vehicle 10, and is equipped with a main body portion 31 that forms the interior surface of the side wall portion 11, and a cover portion 40 that protrudes from the main body portion 31 toward the back surface 60A of the seat back 60 and blocks the gap S between the main body portion 31 and the seat back 60 from above the first engaging portion 61.

[0069] <Other embodiments> The technology disclosed in this specification is not limited to the embodiments described above and illustrated in the drawings, and the following embodiments, for example, are also included in the technical scope.

[0070] (1) In the above embodiment, the mounting seat 43 for attaching the sidewall trim 30 to the upper support member 13 (body 12 side) is configured to extend from the edge of the opening 35 to the inside of the opening 35, but the mounting seat may also be configured to be provided in a part other than the opening.

[0071] (2) In the above embodiment, two mounting seats 43 are provided adjacent to both ends of each opening 35 in the width direction, but they are not limited to being provided adjacent to both ends of the opening, and they may be provided at any position within the opening that does not interfere with the locking portion. Furthermore, the number of mounting seats is not limited to two, and one, three or more may be provided.

[0072] (3) The technical scope also includes a configuration in which the cover part is only the upper wall.

[0073] (4) When the cover portion is configured as only the upper wall, the seat portion of the mounting seat can be provided at both ends of the opening and connected to both the lower edge and the side edge of the opening.

[0074] (5) In the above embodiment, the cover portion 40 protrudes from the edge of the opening 35 toward the rear surface 60A of the seat back 60. However, the cover portion may be configured to rise from a portion other than the edge of the opening, for example, from the interior surface of the vehicle. In short, the cover portion may be configured to cover the engaging portion between the seat back and the body from above.

[0075] (6) In the above embodiment, the sidewall trims 30, 80 are separate bodies, but the sidewall trims may be integrated. [Explanation of symbols]
