Modes for Carrying Out the Invention

[0019] Embodiments of the present invention will be described below with reference to the drawings. In the following description, directions such as front, back, up, down, left, and right shall be the same as the directions of Vehicle 1 unless otherwise specified. In the following description, expressions representing relative or absolute arrangements such as "parallel," "orthogonal," "center," and "coaxial" shall not only strictly represent such arrangements, but also represent states of relative displacement with tolerances or angles and distances that allow the same function to be obtained.

[0020] Figure 1 is a perspective view of the interior of the vehicle compartment S from the rear. Figure 2 is a perspective view of the interior of the vehicle compartment S from the side. Vehicle 1, shown in Figures 1 and 2, is, for example, a minivan-type vehicle. Vehicle 1 comprises a body 2, front side doors 3, rear side doors 4, and a tailgate (not shown).

[0021] The vehicle body 2 defines the passenger compartment S. Specifically, the passenger compartment S is partitioned by pillars (A-pillar, B-pillar, C-pillar, D-pillar, E-pillar), floor, roof, etc. Each pillar is provided in pairs on both sides in the vehicle width direction. The vehicle interior structure according to the present invention is composed of the parts exposed within the passenger compartment S in the vehicle 1.

[0022] Figure 3 is a perspective view showing the front of vehicle 1. As shown in Figure 3, a sub-window 20 is provided between the A-pillar and the B-pillar in the vehicle body 2. A front side door opening 21 is formed between the B-pillar and the C-pillar. As shown in Figure 2, a rear side door opening 22 is formed between the C-pillar and the D-pillar in the vehicle body 2. As shown in Figure 1, a luggage compartment opening 23 is formed between a pair of E-pillars in the vehicle body 2.

[0023] As shown in Figure 3, the front side doors 3 open and close the front side door opening 21. The front side doors 3 are provided in pairs on both sides in the vehicle width direction, corresponding to the front side door opening 21. The front side doors 3 are, for example, hinged doors. The front side doors 3 are attached to the vehicle body 2 so as to be rotatable with the front end opening edge of the front side door opening 21 as the pivot point.

[0024] Figure 4 is a side view of the front side door 3. Figure 5 is a cross-sectional view corresponding to the VV line in Figure 4. As shown in Figures 3 to 5, the front side door 3 comprises a door body 31, a lifting support part 32, and a front side window 33. The door body 31 constitutes the lower half of the front side door 3. The inner surface (design surface) of the door body 31 is composed of a door lining 35 and a door pad 36.

[0025] The door lining 35 constitutes the design surface at the upper end of the door body 31. The door lining 35 is a molded product made of, for example, a resin material. The door lining 35 is formed in an L-shape when viewed in cross-section along the vehicle width direction. Specifically, the door lining 35 comprises a door lining upper surface 35a and a door lining side surface 35b.

[0026] The upper surface 35a of the door lining constitutes the inner portion of the upper end surface of the door body 31 in the vehicle width direction relative to the front side window 33. The upper surface 35a of the door lining extends along a horizontal plane. The side surface 35b of the door lining extends downward from the inner end in the vehicle width direction of the upper surface 35a of the door lining. Specifically, the side surface 35b of the door lining extends outward in the vehicle width direction as it goes downward. Therefore, in the door lining 35, the corner 35c formed by the upper surface 35a of the door lining and the side surface 35b of the door lining is formed at an acute angle. The corner 35c extends linearly in the front-rear direction. The door lining 35 is formed in a color such as black to clearly define the boundary with the front side window 33.

[0027] A sub-lining 37 is provided in front of the door lining 35. The sub-lining 37 constitutes the lower frame portion of the sub-window 20 and is made of the same texture (material, color, etc.) as the door lining 35. The upper surface of the sub-lining 37 has the same width as the upper surface 35a of the door lining and is positioned flush with the upper surface 35a of the door lining.

[0028] The door pad 36 is located on the inner surface of the front side door 3, below the door lining 35. The door pad 36 has a different texture from the door lining 35. Texture refers to the material, color, etc. In this embodiment, the design surface of the door pad 36 is made of a fabric material such as a cloth material or a tricot material, and is formed in a lighter color (for example, gray) than the door lining 35.

[0029] As shown in Figure 5, the door pad 36 includes a bulging portion 36a and a recessed portion 36b. The bulging portion 36a has a curved cross-section that is convex inward in the vehicle width direction. Between the upper end of the bulging portion 36a and the lower end of the door lining side surface 35b, a valley portion 36c is formed that is recessed outward in the vehicle width direction relative to the corner portion 35c. Of the bulging portion 36a, at least the portion located furthest inward in the vehicle width direction is located further inward in the vehicle width direction than the corner portion 35c.

[0030] The recessed portion 36b extends downward from the bulging portion 36a. The recessed portion 36b curves outward in the vehicle width direction as it extends downward. The boundary between the lower end of the bulging portion 36a and the upper end of the recessed portion 36b forms a ridge portion 36d that extends in the front-rear direction.

[0031] As shown in Figure 3, the lifting support portion 32 protrudes upward from the door body 31. The lifting support portion 32, together with the upper edge of the door body 31, constitutes a window frame that defines the window opening 32a. In other words, the upper edge of the door body 31 (door lining 35) constitutes the lower frame portion of the window opening 32a.

[0032] The front side window 33 is supported by the door body 31 and the lifting support part 32, and is movable up and down relative to the door body 31. The front side window 33 opens and closes the window opening 32a.

[0033] As shown in Figure 2, the rear side doors 4 open and close the rear side door opening 22. The rear side doors 4 are provided in pairs on both sides in the vehicle width direction, corresponding to the rear side door opening 22. The rear side doors 4 are, for example, sliding doors. The rear side doors 4 are attached to the vehicle body 2 so as to be slidable in the front-rear direction along the upper and lower opening edges of the rear side door opening 22.

[0034] The rear side door 4, like the front side door 3, comprises a door body 41, a lifting support part 42, and a rear side window 43. The door body 41 constitutes the lower half of the rear side door 4. The door body 41 includes the door lining 45 and the door pad 46. The door lining 45 and the door pad 46 extend in the front-rear direction at the same height as the door lining 35 and door pad 36 of the front side door 3. Since the configuration of the door lining 45 and the door pad 46 is the same as that of the front side door 3, a detailed explanation is omitted.

[0035] The rear side window 43 is supported by the door body 41 and the lifting support part 42, and is movable up and down relative to the door body 41. The rear side window 43 opens and closes the window opening 42a that is partitioned by the door body 41 and the lifting support part 42.

[0036] The tailgate opens and closes the cargo compartment opening 23 (see Figure 1). The tailgate is attached to the vehicle body 2 so as to be rotatable, for example, using the side opening edge or the upper opening edge of the tail opening as pivot points.

[0037] As shown in Figure 1, a front windshield 51 is provided between a pair of A-pillars in the vehicle body 2. Inside the passenger compartment S, a dashboard upper 52 is provided below the front windshield 51. The dashboard upper 52 extends rearward from the lower edge of the front windshield 51. The dashboard upper 52 is a molded product made of, for example, a resin material, and is formed in a color such as black.

[0038] Figure 6 is a perspective view of the interior of the vehicle compartment S, seen from the rear. Figure 7 is a cross-sectional view corresponding to the line VII-VII in Figure 6. As shown in Figures 6 and 7, the dashboard upper 52 includes a defroster opening 52a, a protruding section 52b, a valley section 52c, and a flat section 52d.

[0039] As shown in Figure 7, the defroster opening 52a opens upward at the front end of the dashboard upper 52. The protruding portion 52b is located on the dashboard upper 52, behind the defroster opening 52a. The protruding portion 52b projects upward relative to the defroster opening 52a and extends in the vehicle width direction. In a cross-sectional view from the vehicle width direction, the protruding portion 52b is formed in a triangular shape with one apex pointing upward. Of the protruding portion 52b, the slope located in front of the apex (front slope) has a larger angle with respect to the horizontal plane than the slope located behind the apex (rear slope).

[0040] The valley 52c is located behind the protruding portion 52b on the dashboard upper 52. The valley 52c is located between the protruding portion 52b and the flat portion 52d, and is recessed downward relative to the protruding portion 52b and the flat portion 52d. The valley 52c extends in the vehicle width direction, following the shape of the protruding portion 52b. The flat section 52d extends rearward from the rear edge of the valley section 52c. The flat section 52d is positioned along the horizontal plane. The front-to-back dimension of the flat section 52d is larger than that of the protruding section 52b and the valley section 52c.

[0041] Figure 8 is an enlarged view of the front of the vehicle compartment S. As shown in Figure 8, the upper surface of the flat portion 52d is connected to the upper surface of the sub-lining 37 on both sides of the flat portion 52d in the vehicle width direction. In this embodiment, the upper surface of the flat portion 52d is flush with the upper surface of the sub-lining 37. The front edge of the sub-lining 37 coincides with the boundary portion (ridge portion 52g) between the valley portion 52c and the flat portion 52d.

[0042] As shown in Figure 7, the instrument panel 53 comprises an instrument panel upper 53a and an instrument panel lower 53b. The instrument panel upper 53a is connected to the rear edge of the dashboard upper 52. The instrument panel upper 53a has a different texture from the dashboard upper 52 and the instrument panel lower 53b. In this embodiment, the design surface of the instrument panel upper 53a is formed from a fabric material or the like, similar to the door pad 36.

[0043] The instrument panel upper 53a includes a rear surface 54 that extends downward in a curved shape toward the rear, and a folded surface 55 that extends forward from the lower edge of the rear surface 54. The rear surface 54 extends in the vehicle width direction at the same height as the door pad 36. In the instrument panel upper 53a, the boundary portion 53f between the rear surface 54 and the folded surface 55 extends in the vehicle width direction.

[0044] The lower instrument panel 53b extends downward from the lower edge of the upper instrument panel 53a. Specifically, the lower instrument panel 53b extends diagonally downward and rearward from the front edge of the folded surface 55. The lower instrument panel 53b is formed of a different texture from the upper instrument panel 53a. The lower instrument panel 53b is provided with a vent opening 53c (see Figure 6). The vent opening 53c blows conditioned air supplied from the air conditioning system towards the rear within the passenger compartment S.

[0045] As shown in Figure 1, the passenger compartment S is equipped with multiple rows of seats 61-63 in the front-to-back direction. The vehicle 1 of this embodiment is a three-row type with a first-row seat 61, a second-row seat 62, and a third-row seat 63.

[0046] The first row of seats 61 consists of a driver's seat 65 located on one side in the vehicle width direction and a passenger seat 66 located on the other side in the vehicle width direction, separated by an aisle. The second-row seats 62 consist of a first rear seat 67 located on one side in the vehicle width direction and a second rear seat 68 located on the other side in the vehicle width direction, arranged side by side in the vehicle width direction. The driver's seat 65, passenger seat 66, first rear seat 67, and second rear seat 68 are all independent seats, each capable of accommodating one passenger. The third-row seat 63 is a so-called bench seat type. The third-row seat 63 allows multiple passengers to sit across the width of the vehicle. Note that each of the seats 61-63 may be an individual seat or a bench seat type.

[0047] In the vehicle 1 of this embodiment, a boundary enhancement section 80 is provided inside the passenger compartment S. The boundary enhancement section 80 is intended to allow occupants (especially occupants other than the driver) to recognize the boundary between the inside and outside of the passenger compartment S. The boundary enhancement section 80 comprises a lateral enhancement section 81, a forward enhancement section 82 (see Figure 6), and a seat enhancement section 83. As shown in Figure 2, the lateral emphasis portion 81 extends in a band shape in the longitudinal direction on the inner surface of the passenger compartment S. The lateral emphasis portion 81 comprises a sub-emphasis portion 90, a front window-side emphasis portion 91, a rear window-side emphasis portion 92, a central emphasis portion 93, and a rear emphasis portion 94.

[0048] The sub-enhancement section 90 extends linearly in the front-rear direction along the inner edge in the vehicle width direction of the upper surface of the sub-lining 37. The front window-edge emphasis portion 91 is a band-shaped portion that extends linearly in the front-rear direction along the upper edge of the door body 31 on the front side door 3. The upper edge of the front window-edge emphasis portion 91 is defined by the corner portion 35c, and the lower edge is restricted by the ridge portion 36d. The aforementioned sub-emphasis portion 90 is connected to the front of the upper edge of the front window-edge emphasis portion 91.

[0049] Figure 9 is a perspective view of the interior of the vehicle S, looking forward from the second-row seat 62. As shown in Figure 9, the rear window edge reinforcement portion 92 is a strip-shaped portion that extends linearly in the front-rear direction along the upper edge of the door body 41 on the rear side door 4. Similar to the front window edge reinforcement portion 91, the upper and lower edges of the rear window edge reinforcement portion 92 are defined by the corner portion 45a of the door lining 45 and the ridge portion 46a of the door pad 46, respectively. It extends in the front-rear direction at the same height as the front window edge reinforcement portion 91. In this embodiment, the upper edges and lower edges of the rear window edge reinforcement portion 92 and the front window edge reinforcement portion 91 are positioned at the same height. However, it is sufficient that at least a portion of the rear window edge reinforcement portion 92 and the front window edge reinforcement portion 91 overlap in the vertical direction.

[0050] The central emphasis section 93 is positioned in the front-rear direction between the front window-side emphasis section 91 and the rear window-side emphasis section 92. In this embodiment, the central emphasis section 93 is formed by a C-pillar garnish 101 that covers the C-pillar. The C-pillar garnish 101 extends in the vertical direction and bulges inward in the vehicle width direction relative to the front side door 3 and the rear side door 4. In a plan view, the C-pillar garnish 101 is formed in a C-shape that opens outward in the vehicle width direction and surrounds the B-pillar from both the front and rear sides and from the inside in the vehicle width direction. The C-pillar garnish 101 has an outlet 101a for the seat belt 105. The outlet 101a is formed in a slit shape that extends in the front-rear direction.

[0051] In the C-pillar garnish 101, the portion located below the outlet 101a constitutes the seat belt storage section 101b and the switch storage section 101c. The seat belt storage section 101b is formed as a flat surface with a surface facing inward in the vehicle width direction extending along the vertical direction. Inside the seat belt storage section 101b is a retraction mechanism (not shown) for the seat belt 105.

[0052] The switch storage section 101c is located below the seat belt storage section 101b. The switch storage section 101c bulges inward in the vehicle width direction relative to the switch storage section 101c. Inside the switch storage section 101c is the opening and closing switch (not shown) for the rear side door 4. The opening and closing switch can be operated via an operating section 106 exposed on the rear surface of the switch storage section 101c.

[0053] The central emphasis section 93 extends in a band shape in the front-rear direction in the C-pillar garnish 101, located between the lower edge of the seat belt storage section 101b (the upper edge of the switch storage section 101c) and the outlet 101a. That is, the central emphasis section 93 is positioned at the same height as the front window-edge emphasis section 91 and the rear window-edge emphasis section 92. In this embodiment, the outlet 101a is positioned at the same height as the upper edges of the front window-edge emphasis section 91 and the rear window-edge emphasis section 92. The lower edge of the seat belt storage section 101b is positioned at the same height as the lower edges of the front window-edge emphasis section 91 and the rear window-edge emphasis section 92. The central emphasis section 93 only needs to overlap with the rear window-edge emphasis section 92 and the front window-edge emphasis section 91 in the vertical direction, at least in part.

[0054] As shown in Figure 2, the rear emphasis section 94 is located behind the rear window-edge emphasis section 92 and extends in a band shape in the front-rear direction. The rear emphasis section 94 is formed by the rear pad 111.

[0055] The rear pad 111 is formed with the same texture as the door pad 46 and extends in a band shape in the front-rear direction below the rear garnish 110. Specifically, the lower edge of the rear pad 111 coincides with the lower edge (ridge portion 46a) of the door pad 46. Therefore, the rear emphasis portion 94 extends in the front-rear direction at the same height as the rear window-edge emphasis portion 92.

[0056] A rear garnish 110 is provided above the rear pad 111. The rear garnish 110 is made of a material with a different texture from the rear pad 111 (for example, a molded product made of resin). The rear garnish 110 covers the portion from the D-pillar to the E-pillar from the inside in the vehicle width direction. The lower edge of the rear garnish 110 is at the same height as the lower edge of the door lining 45 and extends linearly in the front-rear direction. Therefore, the lower edge of the rear garnish 110 indicates the boundary with the upper edge of the rear reinforcement portion 94 (the upper edge of the rear pad 111).

[0057] As shown in Figure 1, a recessed portion 110a is formed at the rear end of the rear garnish 110 in the portion located in front of the E-pillar. The recessed portion 110a is recessed outward in the vehicle width direction and opens forward. An outlet 110b for the seat belt 112 for the third-row seat 63 is opened on the inner surface of the recessed portion 110a. The rear end edge of the recessed portion 110a is located behind the rearmost end of the third-row seat 63. In the illustrated example, the rear end edge of the recessed portion 110a coincides with the rear end edge of the rear pad 111.

[0058] As shown in Figure 6, the front emphasis portion 82 extends in the vehicle width direction between the ridge portion 52g of the dashboard upper 52 (the boundary portion between the valley portion 52c and the flat portion 52d) and the boundary portion 53f of the instrument panel upper 53a. That is, the ridge portion 52g defines the upper edge of the front emphasis portion 82. The boundary portion 53f defines the lower edge of the front emphasis portion 82. As shown in Figure 7, the front emphasis portion 82 is located at the same height as the lateral emphasis portion 81 and is connected to the front end of the lateral emphasis portion 81 at both ends in the vehicle width direction. Specifically, the front end edge (ridge portion 52g) of the front emphasis portion 82 is located at the same position in the longitudinal direction as the front end edge of the lateral emphasis portion 81 (sub-emphasis portion 90) on both sides in the vehicle width direction and is connected in the vehicle width direction. As a result, the front-emphasizing section 82 and the side-emphasizing section 81 surround the interior of the passenger compartment S from the front and sides, and also indicate the boundary portions with the lower edges of each window 33, 43, and 51. Therefore, it is possible to give the occupants the feeling of being inside a bucket.

[0059] As shown in Figures 1 and 2, the seat emphasis section 83 comprises a first-row emphasis section 120 provided on the first-row seat 61 and a second-row emphasis section 121 provided on the second-row seat 62. As shown in Figure 9, the first row emphasis section 120 is formed by a seat pocket 120b provided on the rear surface of the seat back 120a. The seat pocket 120b extends across the entire width of the seat back 120a at the same height as the lateral emphasis section 81. Therefore, the upper edge of the seat back 120a defines the upper edge of the first row emphasis section 120, and the lower edge of the seat back 120a defines the lower edge of the first row emphasis section 120.

[0060] The seat pocket 120b is formed with the same texture as the seat back 120a and is attached to the seat back 120a by sewing or the like. Items are inserted into and removed from the seat pocket 120b through an opening that faces upwards.

[0061] A seatback table 120d is provided in the portion of the seatback 120a located below the seat pocket 120b. The seatback table 120d is formed in a plate shape that extends across the entire seatback 120a in the vehicle width direction. The seatback table 120d is configured to be foldable by rotating from its upper end. The seatback table 120d is formed of a different texture than the seat pocket 120b (for example, a molded product of resin material). Therefore, the seatback table 120d marks the boundary with the lower edge of the first row emphasis portion 120.

[0062] As shown in Figure 1, the second-row emphasis section 121 includes a seatback emphasis section 131 and a headrest emphasis section 132. The seatback reinforcement section 131 is designed to provide a clear forward view for the occupants of the third-row seats 63. The seatback reinforcement section 131 comprises an outer shell 133a and a kick plate 133b.

[0063] The outer skin 133a covers the seat cushion (not shown) and the like over the upper part of the seat back 135. The outer skin 133a extends over the entire width of the seat back 120a at the same height as the lateral reinforcement portion 81. The outer skin 133a is formed of a fabric material or the like, similar to the door pad 46 and the like. The kick plate portion 133b is formed below the outer skin 133a and extends in a plate-like shape along the width direction of the vehicle, across the entire seat back 120a. The kick plate portion 133b is formed of a different texture from the outer skin 133a (for example, a molded product of resin material). Therefore, the kick plate portion 133b indicates the boundary with the lower edge of the second row reinforcement portion 121.

[0064] The headrest emphasis portion 132 is formed by the headrest 140 of the second-row seat 62. Specifically, the headrest 140 of the second-row seat 62 has a smaller vertical dimension than the headrest 141 of the first-row seat 61. The upper end surface of the headrest 140 of the second-row seat 62 extends along the horizontal plane. When an occupant of the third-row seat 63 looks forward, the upper end surface of the headrest 140 indicates the boundary with the forward view.

[0065] Thus, in this embodiment, the lateral emphasis portion 81, which is provided in a strip shape along the front-rear direction on the inner surface of the passenger compartment S, has an upper edge formed by the door lining side surface 35b which forms an acute corner portion 35c between the upper surface 35a of the door lining and the upper surface 35a of the door lining. This configuration allows occupants to clearly perceive the boundary between the inside and outside of the vehicle compartment S. In particular, sunlight entering the vehicle compartment S through the side windows 33 and 43 can create shadows on the inner surfaces of the vehicle compartment S (door pads 36 and 46, etc.) by the corners 35c. This makes the boundary between the inside and outside of the vehicle compartment S more clearly perceiveable, which can stabilize the occupants' sense of balance and reduce motion sickness. Moreover, unlike conventional systems that guide the occupant's vision through the operation of actuators, this system can reduce motion sickness regardless of the occupant's physique or the number of passengers.

[0066] In this embodiment, the upper surface 35a of the door lining is arranged along a horizontal plane. This configuration allows for a clearer perception of the boundary between the inside and outside of the vehicle compartment S, further reducing motion sickness.

[0067] In this embodiment, a door pad 36 is provided below the corner portion 35c, which bulges inward in the vehicle width direction compared to the corner portion 35c. With this configuration, the door pads 36 and 46 are more easily illuminated by sunlight, etc. Therefore, the shadows formed by the corners 35c can be made more prominent, and the boundary between the inside and outside of the vehicle interior S can be made more clearly recognizable.

[0068] In this embodiment, a switch storage section 101c is provided below the central emphasis section 93, bulging inward in the vehicle width direction from the central emphasis section 93 and indicating the boundary with the lower edge of the central emphasis section 93. An open / close switch for opening and closing the rear side door 4 is stored inside the switch storage section 101c, and an operating section 106 for operating the open / close switch is exposed on the surface of the switch storage section 101c. With this configuration, the switch storage section 101c bulges inward in the vehicle width direction relative to the central emphasis section 93, making it easier for occupants to recognize the central emphasis section 93. Moreover, since the open / close switch can be stored inside the switch storage section 101c, layout flexibility can also be improved.

[0069] In this embodiment, the rear edge of the rear-emphasizing portion 94 extends to the rear edge of the recessed portion 110a. This configuration allows the lateral reinforcement section 81 to extend to the rear of the third-row seat 63. Therefore, it becomes easier for occupants of the third-row seat 63 to recognize the boundary between the inside and outside of the vehicle interior S.

[0070] In this embodiment, the forward-emphasizing portion 82 provided at the front end of the passenger compartment S is located behind the defroster opening 52a that opens on the upper surface of the dashboard upper 52, and is configured to have a stepped portion (a portion extending from the protruding portion 52b to the flat portion 52d) above the defroster opening 52a. This configuration allows the occupants to clearly perceive the boundary between the inside and outside of the vehicle compartment S. In particular, the stepped portion provided behind the defroster opening 52a makes it difficult to see the defroster opening 52a from the rear. This improves the aesthetic appearance from the perspective of the occupants within the vehicle interior S.

[0071] In this embodiment, the stepped portion comprises a protruding portion (front base) 52b, a flat portion 52d located behind the protruding portion 52b, and a valley portion 52c located between the protruding portion 52b and the flat portion 52d, and the boundary portion (ridge portion 52g) between the valley portion 52c and the flat portion 52d constitutes the upper edge of the front-emphasized portion 82. With this configuration, sunlight entering the passenger compartment S through the front windshield 51 can cast a shadow on the upper surface of the dashboard upper 52 (the portion located between the valley 52c and the ridge 52g) using the protruding portion 52b. This makes the boundary between the inside and outside of the passenger compartment S more clearly recognizable. In particular, by forming a valley 52c between the protruding portion 52b and the flat portion 52d, the boundary between the valley 52c and the flat portion 52d (ridge portion 52g) makes the boundary between the inside and outside of the vehicle compartment S more clearly recognizable. Furthermore, by forming the valley portion 52c, it becomes easier to secure the height of the protruding portion 52b, making the defroster opening 52a less visible.

[0072] In this embodiment, the instrument panel upper 53a is located behind the vent opening 53c and includes a boundary portion 53f that forms the lower edge of the forward-emphasizing portion 82. This configuration makes it easier for occupants to recognize the lower edge of the forward-emphasizing section 82. Moreover, sunlight entering the passenger compartment S through the front windshield 51 can create a shadow on the lower instrument panel 53b by the boundary section 53f. This makes the boundary between the inside and outside of the passenger compartment S more clearly recognizable, thereby reducing motion sickness.

[0073] In this embodiment, the front end of the lateral emphasis portion 81 is connected to the front emphasis portion 82. This configuration gives the occupants the feeling of being inside a bucket. This helps stabilize the occupants' sense of balance and reduces motion sickness.

[0074] In this embodiment, the rear surfaces of the seats 61 and 62 are provided with reinforced portions 120 and 121 that extend in a strip-like shape along the vehicle width direction. This configuration allows occupants to clearly perceive the boundary between their forward view and their surroundings. This helps stabilize their sense of balance and reduces motion sickness.
