Next, the arrangement of each seat will be described with reference to FIGS. 1 to 3 and FIG. FIG. 8 is a perspective view showing one embodiment of the structure of the vehicle of the present invention.
First, as shown in FIGS. 1 and 8, the vehicle 1 is provided with three seats (seats) 62, 64, 66 arranged in the vehicle width direction. In the present embodiment, the seat 62 at the center in the vehicle width direction is a driver seat provided facing the steering wheel 28. Adjacent to the right side and the left side are left and right seats 64 and 66 for passengers.
In the state shown in FIG. 1 and FIG. 8 (first state), the left seat 64 and the right seat 66 are provided on the second floor 76 and above the slope portion 83 described above. Further, the left seat 64 and the right seat 66 are provided in front of the wheel house 4 at positions that do not interfere with the wheel house 4.

  As shown in FIGS. 1, 2, and 8, these seats 62, 64, 66 are all provided on the upper surface portion 80 of the second floor 76. Here, the occupant model shown in FIG. 2 shows an occupant model A seated in the central seat (driver's seat) 62 and an occupant model B seated in the left seat 64. As represented by the occupant model A, the occupant seated on the central seat 62 places his / her feet on the first floor 70. It should be noted that the feet are placed on the first floor 70 in the same manner as the passenger seated in the right seat 66. On the other hand, as represented by the occupant model B, the occupant seated on the left seat 64 puts his feet on the floor tunnel 72 of the first floor 70. As described above, the first floor 70 is formed as a footrest.

  In general, the floor on which the occupant places his / her feet preferably has a low vertical position in the vehicle body so that the space under the occupant's knees can be expanded. In particular, in the driver's seat, the driver must ensure sufficient depth and depth to the dash panel (dash lower panel) so that the driver can depress the pedals such as the brake and accelerator. On the other hand, since the exhaust system member must be passed to the rear of the vehicle body under the floor, a floor tunnel extending in the vehicle longitudinal direction is conventionally provided at the center portion in the vehicle width direction on the floor extending to a low position.

In the present invention, such a floor tunnel is offset to the left or right side in the vehicle width direction. On the other hand, according to the present invention, a three-seat arrangement in which three seats are arranged in the vehicle width direction is provided, and a cargo space is provided behind the seat, thereby shortening the vehicle body. The driver's seat 62 is disposed in the center in the vehicle width direction, and the passenger seats 64 and 66 are disposed on the left and right sides thereof.
In such vehicle packaging, according to the present invention in which the floor tunnel is offset to the left or right in the vehicle width direction, the space below the knee of the driver seat 62 arranged at the center in the vehicle width direction is the same as the conventional driver seat in the left and right arrangement or It is possible to achieve both of securing more than that and securing a space through which the exhaust pipe passes in the front-rear direction. The same applies to the passenger seat (passenger seat 66 in the present embodiment) disposed on the side opposite to the side where the floor tunnel 72 is offset.

  However, the space below the knee of the passenger in the passenger seat on the side where the floor tunnel 72 is offset becomes smaller. In the present embodiment, the floor tunnel 72 is offset to the left side on the assumption that the vehicle is running on the right lane. In this case, the knee space of the left passenger seat 64 is reduced. As described above, in the present embodiment, the passenger seat 64 with the floor tunnel located below is arranged on the side of the roadway where there is little opportunity to board from the sidewalk side (left side if this is a right lane run (this embodiment is equivalent)) If so, it is placed on the right). Therefore, the seats with higher necessity (right seat (66) in the case of right lane traveling (this embodiment is equivalent), left seat in the case of left lane traveling) and the driver seat 62 in the center) It is possible to realize a state of two passengers with a space below the knee.

  Next, as shown in FIG. 2, the fuel tank 34 is disposed below the second floor 76 and the floor tunnel 72, and these lower spaces are effectively used. In the case of a hybrid vehicle, a battery may be arranged together with such a fuel tank, and in the case of an electric vehicle, a battery may be arranged instead of the fuel tank.

  Next, in the embodiment of the present invention, the space above the third floor 84 and the space on the rear side of each seat 60, 62, 64 is a luggage space. On the other hand, the rear suspension 40 and the silencer 32 described above are disposed below the third floor 84, and the lower space of the third floor 84 is effectively used.

For example, the seats 62, 64, 66 arranged in a row in the vehicle width direction are arranged on the second floor 76 higher than the foot floor (first floor 70), and the fuel tank 34 (and / or below) A battery having a shorter overall length can be obtained by effectively using the vehicle interior space and the space below the vehicle body. In this case, for example, there is an advantage that the yaw moment can be reduced by bringing the second floor 76 to the center in the longitudinal direction of the vehicle body.
Furthermore, since the seats 62, 64, and 66 are disposed on the second floor 76 that is higher than the foot floor (the first floor 70), the required height of the seat legs can be reduced. In this case, the weight of the vehicle is also reduced.

Next, the displacement state of the sheet will be described with reference to FIGS. 1, 2, and 8 to 11. 9, FIG. 10 and FIG. 11 are a plan view, a side view and a perspective view corresponding to FIG. 1, FIG. 2 and FIG. 8, respectively. FIG. 9 is a diagram illustrating a state at a second position that is inclined obliquely with respect to the first position illustrated in FIG.
In the embodiment of the present invention, the left and right seats 64 and 66 are displaced obliquely in the vehicle longitudinal direction and the vehicle width direction along the slope portion 83 by a slide rail mechanism (not shown) in plan view. In view, it is displaced in the vertical direction of the vehicle. Here, first, the case where the left and right seats 64 and 66 are in the first position (front and lower position, first state) will be described with reference to FIGS. 1, 2, and 8.

  As shown in FIGS. 1, 2, and 8, when the left and right seats 64, 66 are in the first position, the front edge portions 64a, 66a of the seat cushions of the seat seats 64, 66 are in the longitudinal direction of the vehicle body. The front edge 62a of the seat cushion of the central seat (driver's seat) 62 coincides with the front seat 62a. Further, the front edge portions 62a, 64a, 66a of each seat cushion are at the same position as the kick-up portion 78 of the second floor 76 in plan view.

  Similarly, as shown in FIGS. 2 and 8, in the first position, the seat cushion seat surfaces 64 b and 66 b of the left and right seats 64 and 66 have a seat cushion seat surface 62 b of the center seat 62. Is consistent with Similarly, as shown in FIGS. 1 and 8, in the first position, the seat backs 64c and 66c of the seat are coincident with the seat back 62c of the center seat 62.

On the other hand, the seat cushion seat surfaces 64b and 66b and the seat backs 64c and 66c of the left and right seats 64 and 66 for passengers have a width in the vehicle width direction of the seat 62b and the seat of the central seat 62 which is a driver seat. It is smaller than the width of the back 62c.
By arranging such left and right seats 64 and 66 in the first position, for example, when a passenger is not seated in the left and right seats 64 and 66 or a small child is seated, the capacity of the luggage compartment is increased. I can do it. Also, objects can be placed on such left and right seats 64 and 66.

Next, the case where the left and right side seats 64 and 66 are in the second position (rear and upper position, second state) will be described with reference to FIGS. 9, 10, and 11.
The left and right seats 64 and 66 are displaced from the first position described above to the second position shown in FIGS. 9, 10 and 11 along the slope portion 83 described above.
In this second position, the left and right seats 64 and 66 are located rearward and upward in a side view with respect to the central seat that forms the driver's seat as shown in FIGS. As shown, the front part of the seat is oriented obliquely outward in the vehicle width direction so as to be separated from the center seat in plan view.

Specifically, as shown in FIGS. 9 and 11, the positions of the front edge portions 64a and 66a of the seat cushions of the left and right seats 64 and 66 in the longitudinal direction of the vehicle body are more than the front edge portion 62a of the seat cushion of the central seat 62. Is also on the rear side. In this case, the left and right seats 64 and 66 are lowered rearward to a position overlapping the wheel house 4 in a side view.
Similarly, as shown in FIGS. 10 and 11, in the second position, the height position of the seat cushion seat surfaces 64 b and 66 b of the left and right seats 64 and 66 is the height of the seat cushion seat surface 62 b of the center seat 62. The position is higher than the vertical position.
