However, in the conventional vehicle interior structure described above, when the vehicle interior space is expanded, part of the lower surface (floor surface) of the vehicle interior space is formed by the back surface of the seat back. There was a possibility that the comfort inside the room would be lost. For example, the cushioning material on the back side of the seatback is thinner than that on the front side of the seatback, where the passenger rests their body, and a metal seatback frame is often placed inside the backside. . For this reason, if the back surface of the seat back becomes part of the lower surface of the vehicle interior space when the vehicle is expanded, the occupant is likely to feel uncomfortable (hardness) in the back surface of the seat back. For example, if a rotating and deployable auxiliary table is installed on the back of the seat back, the auxiliary table cannot be used when the cabin space is expanded, making it difficult for passengers to eat or do office work using a PC. turn into.

The present invention has been made with attention to the above points, and an object of the present invention is to provide a vehicle interior structure that can improve comfort in a vehicle interior space that is expanded depending on the state of the vehicle seat.

The seat portion 21 of the front seat 2 is a portion where an occupant is seated. A seat cushion 21B having elastic properties is installed on the upper part of a seat frame 21A that constitutes the skeleton of the seat 21. A seating surface is formed on the upper surface of the seat cushion 21B, and is covered with a seat cover (not shown). A reclining mechanism 23 is provided at the rear of the seat frame 21A.

The seat back 22 of the front seat 2 is a portion extending upward from the rear portion of the seat portion 21, and is configured to support the upper body of an occupant seated on the seat portion 21. The seat back 22 is used in an upright state when driving the vehicle. 1 and 2 show a state in which the seat back 22 is reclined toward the rear of the vehicle by the reclining mechanism 23.

A seat back frame 22A (dotted line) that constitutes the skeleton of the seat back 22 is formed into a substantially rectangular shape by curving a pipe-shaped member. When the seat back 22 is in an upright state, a seat back cushion 22B made of a cushioning material having elastic properties is installed at the front part of the seat back frame 22A.

A seat surface (support surface) that supports the back of the occupant is formed on the front surface of the seat back cushion 22B in the upright state. There is. Further, a headrest 24 (see FIG. 9, which will be described later) is removably attached to the upper surface of the seat back cushion 22B in the upright state. The headrest 24 supports the head of an occupant seated on the seat portion 21 of the front seat 2. Note that in FIGS. 1 and 2, the headrest 24 is removed from the seat back cushion 22B. The seat back cushion 22B is covered with a seat back cover (not shown).

The front seat 2 as described above has a reclining mechanism 23 that allows the seat back 22 to be adjusted to a horizontal position where the rear part of the seat surface of the seat back 22 is horizontal when the seat back 22 is tilted backwards. The structure is as follows. Note that the horizontal position does not need to be strictly horizontal as long as the rear portion of the seat surface of the seat back 22 is approximately horizontal. Specifically, for example, the rear portion of the seat surface of the seat back 22 may be within a range of ±10°, preferably within a range of ±5° with respect to the horizontal direction. Further, although not shown in the drawings, the seat back 22 of the front seat 2 can be tilted forward by a reclining mechanism 23.

In this embodiment, when the seatback 22 of the front seat 2 is folded backward to the horizontal position, the rear seat 3 located behind the front seat 2 is stored in the foot space as shown in FIGS. 1 and 2. It is necessary to do so. The rear seat 3 is a tilt-down type (dive-down type) vehicle seat similar to that installed in the interior of the conventional vehicle described above.

The rear seats 3 are installed as a right rear seat and a left rear seat in the vehicle interior, respectively, spanning the rear part of the front floor 11 and the front part of the rear floor 12 of the vehicle interior. The rear seat 3 includes a rear seat portion 31 and a rear seat back 32. The rear seat 3 is configured such that the vehicle interior space can be expanded by folding the rear seat back 32 forward and storing it together with the rear seat portion 31 in the front leg space.

Specifically, the rear seat portion 31 is configured to be adjustable between a storage position located on the front floor 11 side of the vehicle interior and an expanded position located on the rear floor 12 side above the storage position. The storage position of the rear seat portion 31 is a position that utilizes the foot space in front of the rear seat 3, and corresponds to a recess provided at the rear of the front floor 11. The rear seat back 32 is configured to be adjustable to an overlapping position where it overlaps the rear seat portion 31. The rear seat 3 shown in FIGS. 1 and 2 is adjusted to a tilt-down state (storage state) with the rear seat back 32 in the stacked position and the rear seat portion 31 in the storage position.

In this embodiment, the rear seat 3 is adjusted to a tilt-down state, and the seatback 22 of the front seat 2 is tilted backward to a horizontal position, thereby expanding the vehicle interior space into a bed mode. . When the vehicle interior space is expanded in the bed mode, the luggage board 4 is supported by the support portion 5 at a facing position where the rear surface 22C of the seat back 22 in the horizontal position and the front surface 4A of the luggage board 4 face each other. Note that the rear surface 22C of the seat back 22 in the horizontal position is the upper surface of the seat back 22 in the upright state. In other words, the attachment surface of the seat back cushion 22B to which the headrest 24 is attached corresponds to the rear surface 22C of the seat back 22 in the horizontal position.

The vertical range α shown in FIG. 2 represents a range in which it is preferable to arrange the front surface 4A of the luggage board 4 at the facing position. In this embodiment, the upper surface (board surface) of the luggage board 4 supported by the support part 5 is arranged below the upper end of the rear surface 22C of the seat back 22 in the horizontal position, and the seat back frame 22A ( It is arranged at a position above the upper surface (dotted line in FIG. 2). Specifically, the upper surface of the seat back frame 22A in this embodiment corresponds to the upper surface of the upper frame portion of the substantially rectangular seat back frame 22A that is located on the side where the headrest 24 is attached and extends in the seat width direction. Further, the position above the upper surface of the seat back frame 22A includes a position where the upper surface of the seat back frame 22A and a portion of the front surface 4A of the luggage board 4 overlap in the front-rear direction. Hereinafter, an example of a specific structure of the support part 5 that supports the luggage board 4 at the facing position will be described in detail with reference to FIGS. 3 and 4.

FIG. 3 is an enlarged perspective view showing the lower part of the side trim 13 where the support portion 5 is formed in this embodiment. Moreover, FIG. 4 is a side view of the lower part of the side trim 13 of FIG. 3 viewed from inside the vehicle interior.

As shown in FIGS. 1, 3, and 4, the support portions 5 are formed at the lower portions of the left and right side trims 13 that constitute the side walls of the rear portion of the vehicle compartment. The side trim 13 is disposed between a rear edge 14A of a rear door opening 14 provided at the side of the vehicle body and a side edge 15A of a back door opening 15 provided at the rear of the vehicle body, and extends in the vehicle vertical direction. It is extending. In the wall surface (reference surface) of the side trim 13, the rear portion in the longitudinal direction of the vehicle is located on the inner side in the vehicle width direction than the front portion. In this embodiment, the wall surface of the side trim 13 is gradually inclined inward in the vehicle width direction toward the rear side of the vehicle. That is, the distance (width) between the wall surface of the right side trim 13 and the wall surface of the left side trim 13 gradually becomes narrower toward the rear of the vehicle. Note that FIG. 1 shows only the right side trim 13, and the illustration of the left side trim 13 is omitted. In FIGS. 3 and 4, the lower part of the right side trim 13 is shown enlarged. Since the wall surface of the side trim 13 is formed in the above-mentioned inclined shape, when installing the luggage board 4 on the support part 5, the luggage board 4 is placed in contact with the wall surface of the side trim 13. 4 can be positioned, and the load transmitted to the luggage board 4 can be distributed to the side trim 13.

The support section 5 in this embodiment has, for example, a three-stage configuration, and includes a first support section 51, a second support section 52, and a third support section 53. In such a three-tiered support section 5, it is the first support section 51 that supports the luggage board 4 at the facing position (α) in the bed mode (FIG. 1).

As shown in FIGS. 3 and 4, the first support portion 51 is formed at the lower end side of the lower portion of the side trim 13, on the upper surface of the bulge that bulges inside the vehicle interior. A tire house (not shown) corresponding to the rear wheel of the vehicle is arranged on the outside of this bulge. The first support part 51 extends in the longitudinal direction of the vehicle, and is divided into a front support part 51A and a rear support part 51B, with a recessed part formed toward the front of the intermediate part and recessed toward the outside of the vehicle interior in between. There is. Each upper surface of the front support portion 51A and the rear support portion 51B is a substantially horizontal flat surface. The width of the upper surface of the rear support portion 51B in the vehicle width direction becomes narrower toward the rear of the vehicle, making it difficult for the rear support portion 51B to bend in the vertical direction. Note that the recessed portion is used when the luggage board 4 is placed vertically.

The first support portion 51 supports the luggage board 4 from below by placing the side portions of the luggage board 4 in the vehicle width direction on its flat upper surface. In other words, the upper surface of the first support portion 51 serves as a support surface for the luggage board 4. The luggage board 4 placed on the upper surface of the first support portion 51 is set so that its width in the vehicle width direction is wider than the width of the back door opening 15 in the vehicle width direction (FIG. 1). Note that details of the luggage board 4 will be described later. Therefore, at least a portion of the upper surface (support surface) of the first support portion 51 is located on the outer side in the vehicle width direction than the side edge portion 15A of the back door opening 15 when viewed from the vehicle longitudinal direction (FIG. and Figure 3). That is, the entire support surface of the first support portion 51 may be provided on the outer side in the vehicle width direction than the side edge 15A of the back door opening 15, or a portion of the support surface may be provided on the outside of the side edge 15A of the back door opening 15. It may be provided on the outer side in the vehicle width direction than the side edge portion 15A, and the remainder of the support surface may be provided on the inner side in the vehicle width direction than the side edge portion 15A of the back door opening 15.

The front surface 4A of the luggage board 4 supported by the first support portion 51 is in a position facing the rear surface 22C of the seat back 22 which is in the horizontal position as described above (FIGS. 1 and 2). In other words, when viewed from the longitudinal direction of the vehicle, the luggage board 4 supported by the first support portion 51 is arranged so as to overlap the rear surface 22C of the seat back 22 (the mounting surface of the headrest 24) in a horizontal position.

Further, the side trim 13 in this embodiment is provided with a first contact portion 61 that comes into contact with the luggage board 4 placed on the upper surface of the first support portion 51 . The first contact portion 61 positions the luggage board 4 in the front-back direction by restricting movement of the luggage board 4 supported by the first support portion 51 in the front-back direction. Specifically, the first contact portion 61 has a convex shape that protrudes upward from the upper surface of the first support portion 51 . As shown in FIG. 1, on the side part of the luggage board 4 in the vehicle width direction, a concave abutted part 4B that is recessed inward in the vehicle width direction corresponds to the convex shape of the first abutment part 61. A plurality of them (here, two on each of the left and right sides) are provided at intervals in the front-rear direction. That is, in the present embodiment, the positioning of the luggage board 4 in the front-rear direction is performed by the combination of the first abutting part 61 provided on the side trim 13 and the plurality of abutted parts 4B provided on the luggage board 4. It is being said.

When placing the luggage board 4 on the upper surface of the first support part 51, if the luggage board 4 is placed so that the first contact part 61 comes into contact with the abutted part 4B on the rear side of the luggage board 4, The rear surface 22C of the seat back 22 and the front surface 4A of the luggage board 4 are arranged at a position adjacent to each other (first facing position). The luggage board 4 shown in solid lines in FIG. 2 represents a state in which it is disposed at the first facing position. Note that "adjacent" at the first facing position includes "contact" and "proximity without contact."

On the other hand, when the luggage board 4 is placed on the upper surface of the first support part 51, the luggage board 4 is placed so that the first contact part 61 contacts the front abutted part 4B of the luggage board 4. In this case, the front surface 4A of the luggage board 4 is arranged at a position (second facing position) that is rearward of the first facing position with respect to the rear surface 22C of the seat back 22. In FIG. 2, the front surface 4A' of the luggage board 4', which is indicated by a two-dot chain line, represents a state in which it is disposed at the second facing position.

In other words, the luggage board 4 supported by the first support part 51 is positioned at either the first facing position or the second facing position, which are different in the front-rear direction with respect to the rear surface 22C of the seat back 22 in the horizontal position. It turns out. Such positioning of the luggage board 4 is performed appropriately according to the heights of the occupants (FIG. 2) lying on the front seat 2 and the luggage board 4 in the expanded vehicle interior space in the bed mode.

Furthermore, a bush 7 (elastic body) is removably fixed to the lower part of the side trim 13 in this embodiment at a position higher than the upper surface (board surface) of the luggage board 4 supported by the first support part 51. A bushing fixing portion 71 is provided for this purpose (FIGS. 1, 3, and 4). The bush 7 is fixed to the bush fixing part 71 and protrudes inward from the wall surface of the side trim 13, and the lower part of the bush 7 is attached to the upper surface of the luggage board 4 supported by the first support part 51. It is configured to come into contact with. The bush fixing portion 71 is preferably provided adjacent to the first contact portion 61 . By arranging the bush 7 adjacent to the first contact portion 61, even if the first contact portion 61 receives a load from the front and back directions and vibrates, the bush 7 can easily absorb the vibration.

The second support part 52 and the third support part 53 in the three-tiered support part 5 are compatible with a work mode in which the luggage board 4 is used as a table for eating or doing office work using a PC, etc. be. The second support part 52 is arranged above the first support part 51 at a spacing, and the third support part 53 is arranged above the second support part 52 at a spacing. (Figures 3 and 4).

Specifically, the second support portion 52 is formed in the middle portion of the lower part of the side trim 13 in the vertical direction so as to protrude toward the inside of the vehicle interior. The second support portion 52 extends in the longitudinal direction of the vehicle, and is divided into a front support portion 52A and a rear support portion 52B at a position above the recessed portion of the first support portion 51 described above. Each upper surface of the front support portion 52A and the rear support portion 52B is a substantially horizontal flat surface. The width of the upper surface of the rear support portion 52B in the vehicle width direction becomes narrower toward the rear of the vehicle, making it difficult for the rear support portion 52B to bend in the vertical direction. The second support portion 52 supports the luggage board 4 from below by having the side portions of the luggage board 4 in the vehicle width direction placed on its flat upper surface.

Further, on the upper surface of the second support portion 52, a second contact portion 62 having a convex shape and projecting upward is provided. The second contact portion 62 corresponding to the second support portion 52 is arranged on the rear side of the first contact portion 61 corresponding to the first support portion 51 in the front-rear direction. Similar to the first contact portion 61 described above, the second contact portion 62 restricts the luggage board 4 supported by the second support portion 52 from moving in the front-rear direction. The reason why the second contact part 62 is arranged at the rear side of the first contact part 61 is that when the rear seat 3 is expanded to a state where a passenger can sit, the luggage supported by the second support part 52 This is to prevent the front surface 4A of the board 4 from interfering with the rear seat back 32.

Furthermore, a bush fixing part 72 for removably fixing the bush 7 described above is also provided at the lower part of the side trim 13 at a position higher than the upper surface of the luggage board 4 supported by the second support part 52. There is. The bush 7 fixed to the bush fixing part 72 protrudes inward from the wall surface of the side trim 13, and the lower part of the bush 7 touches the upper surface of the luggage board 4 supported by the second support part 52. are configured to abut. The bush fixing part 72 is preferably provided adjacent to the second abutting part 62 similarly to the bush fixing part 71 described above.

The third support portion 53 is formed at the upper portion of the lower portion of the side trim 13 so as to protrude toward the interior of the vehicle. The third support portion 53 extends in the longitudinal direction of the vehicle, and is divided into a front support portion 53A and a rear support portion 53B at a position above the recessed portion of the first support portion 51 described above. A flat surface is formed at each upper end of the front support portion 53A and the rear support portion 53B. The width of the upper surface of the rear support portion 53B in the vehicle width direction becomes narrower toward the rear of the vehicle, making it difficult for the rear support portion 53B to bend in the vertical direction. The third support portion 53 supports the luggage board 4 from below by having a side portion of the luggage board 4 in the vehicle width direction placed on a flat upper surface.

Further, on the upper surface of the third support portion 53, a third contact portion 63 having a convex shape and projecting upward is provided, similar to the second contact portion 62 described above. The third contact portion 63 is arranged on the rear side of the second contact portion 62 in the front-rear direction. Further, in the lower part of the side trim 13, similar to the bush fixing part 72 described above, there is provided adjacent to the third contact part 63 at a position higher than the upper surface of the luggage board 4 supported by the third support part 53. A bush fixing portion 73 is provided.

In addition, in the lower part of the side trim 13, a portion located behind each of the first support portion 51, the second support portion 52, and the third support portion 53 is provided with a raised portion extending toward the inside of the vehicle interior and extending in the vertical direction. , a first regulating section 81, a second regulating section 82, and a third regulating section 83 are provided (FIGS. 3 and 4). The first to third regulating parts 81 to 83 have a vertical surface that regulates rearward movement of the luggage board 4 supported by the first to third supporting parts 51 to 53, and extend forward from the upper end of the vertical surface, It has a lower surface that restricts the upward movement of the luggage board 4, an inclined surface that extends upward and forward from the front end of the lower surface, and a connecting surface that extends upward from the front end of the inclined surface. There is. The lower end portions of the vertical surfaces of the first to third regulating portions 81 to 83 are connected to the upper surfaces (supporting surfaces) of the first to third supporting portions 51 to 53. Further, the upper end portions of the connecting surfaces of the first and second regulating portions 81 and 82 are connected to the lower surfaces of the second and third regulating portions 82 and 83.

By providing the first to third restriction parts 81 to 83 as described above on the side trim 13, the rear support parts 51B to 53B of the first to third support parts 51 to 53 are connected to each other. Therefore, when the luggage board 4 supported by any of the first to third support parts 51 to 53 is in use, the load applied to the rear support part is transferred to the other rear support parts via the first to third restriction parts 81 to 83. It will be distributed to different departments. Therefore, it is possible to suppress vibrations of the luggage board 4 itself or vibrations caused by elastic deformation of each of the first to third support parts 51 to 53. Note that the first to third regulating parts 81 to 83 as described above may be arranged on the front side of the first to third supporting parts 51 to 53, respectively.

Regarding the support part 5 having the three-stage structure as described above, the area of the upper surface of the first support part 51 (the front support part 51A and the rear support part 51B) used in the bed mode is equal to the area of the upper surface of the first support part 51 used in the bed mode. It is preferable to set the area to be larger than the area of the upper surface of each of the second support portion 52 (front support portion 52A and rear support portion 52B) or the third support portion 53 (front support portion 53A and rear support portion 53B). By setting the area of the upper surface (supporting surface) of the first support part 51 in this way, the load (body weight) of the occupant is most easily applied to the support part 5 via the luggage board 4 in the bed mode. It can be easily received on the upper surface of the first support portion 51 (front support portion 51A and rear support portion 51B).

Here, a specific example of the configuration of the luggage board 4 in this embodiment will be described in detail with reference to FIGS. 5 to 7.
FIG. 5 is an enlarged perspective view showing a state in which the luggage board 4 is arranged so that the first board surface used in bed mode is the top surface. Further, FIG. 6 is an enlarged perspective view showing a state in which the luggage board 4 is arranged so that the second board surface used in the work mode is the upper surface. Furthermore, FIG. 7 is a conceptual diagram for explaining the relationship between the width of the luggage board 4 and the vertical distance between the first to third support parts 51 to 53.

As shown in FIGS. 5 and 6, when the luggage board 4 is placed horizontally, the above-mentioned front surface 4A faces the front of the vehicle. A contact portion 4B is formed. The luggage board 4 has a first board surface portion 4C and a second board surface portion 4D that face the vehicle in the vertical direction, and is arranged so that the first board surface portion 4C faces the vehicle in the bed mode (FIG. 5). In the mode, the second board surface portion 4D is arranged so as to face above the vehicle (FIG. 6). The first board surface portion 4C used in the bed mode is set to have greater flexibility or elasticity than the second board surface portion 4D used in the work mode. Specifically, in the second board surface portion 4D, a reinforcing member made of a sheet metal is arranged inside a resin-molded member, for example. However, the reinforcing member can be omitted if the resin molded member has sufficient rigidity. The first board surface portion 4C has a board surface made of a skin material, and a cushion material is provided between the skin material and the resin molded member of the second board surface portion 4D.

In the luggage board 4 as described above, the first board surface portion 4C, which is highly flexible or elastic, is placed on the top surface in the bed mode, so that the occupant can place the first board surface portion 4C of the luggage board 4 on the floor. When you rest your body on the bed, you can prevent the floor from feeling hard. On the other hand, by arranging the second board surface portion 4D, which has less flexibility or elasticity, on the upper surface in the work mode, meals, office work, etc. can be stably performed. By providing a difference in flexibility or elasticity between the first and second board surface portions 4C and 4D in this manner, the board surface of the luggage board 4 that is suitable for the mode can be easily selected by simply reversing the luggage board 4. becomes possible.

Further, the second board surface portion 4D used in the work mode may be formed with a plurality of recesses 4E to 4H, as shown in FIG. The first recessed portion 4E extends in the vehicle width direction, and is formed in the shape of a horizontally long groove whose width in the vehicle longitudinal direction is shorter than its length in the vehicle width direction. A so-called touch-panel type thin portable device that does not have a keyboard can be inserted into the first recess 4E and placed vertically. By placing the thin portable device vertically using the first recess 4E in this way, it is possible to easily view and touch the display of the device while doing office work. The second recess 4F is a substantially rectangular and flat recess extending in the vehicle longitudinal direction and vehicle width direction. Office equipment such as a notebook computer can be placed in this second recess 4F.
