(A) is a side view which shows the arrangement structure of the vehicle seat of embodiment, (b) is the top view.

Hereinafter, the arrangement structure of the vehicle seat of the present embodiment will be described with reference to FIG.
As shown in FIGS. 1A and 1B, a hatchback type vehicle 10 includes a stair-like floor 12 that rises from the front to the rear in a vehicle interior 11. The floor 12 of the present embodiment is a three-stage floor, in which the front is a first floor 12a, the middle is a second floor 12b, and the rear is a third floor 12c. The vehicle 10 includes a driver seat (a first seat S1 described later) in which a driver sits in front of the vehicle interior 11 (on the first floor 12a side), and a handlebar 13 in front of the driver seat. The second floor 12b is at a position higher than the first floor 12a by a height H1, and the third floor 12c is at a position higher by a height H2 than the second floor 12b. The dimension of the second floor 12b in the front-rear direction is shorter than the dimension of the first floor 12a and the third floor 12c in the front-rear direction, and is set to half or less. The dimension of the second floor 12b in the front-rear direction is shorter than the dimension of the second sheet S2 described later in the front-rear direction. The third floor 12c of the present embodiment includes a protruding portion 14 that protrudes by a height H3 from a portion on the rear side in the front-rear direction and on the left side in the left-right direction (vehicle width direction) of the third floor 12c.

  One or two sheets S are arranged on the first to third floors 12a to 12c. A first seat S1 (driver's seat) is disposed on the right side of the first floor 12a. A second seat S2 is arranged on the left side of the second floor 12b. A third sheet S3 is disposed in front of and on the right side of the third floor 12c, and a fourth sheet S4 is disposed on the protrusion 14. That is, the positions of the first to fourth sheets S1 to S4 increase in the order of the first sheet S1, the second sheet S2, the third sheet S3, and the fourth sheet S4. Further, the first sheet S1 and the third sheet S3 are arranged in the front-rear direction, and the second sheet S2 and the fourth sheet S4 are arranged in the front-rear direction at positions different from the first sheet S1 and the third sheet S3 in the left-right direction. The first to fourth sheets S1 to S4 are alternated in the left-right direction.

  The heights H1 to H3 are such that the head of the occupant C of the third seat S3 is located above the head of the occupant A of the first seat S1, and the head of the occupant D of the fourth seat S4 is The second seat S2 is set to be located above the head of the occupant B. Thus, the field of view of the occupant C of the third seat S3 is not blocked by the occupant A (driver) of the first seat S1. Further, the field of view of the occupant D of the fourth seat S4 is not obstructed by the occupant B of the second seat S2.

  Each of the first to fourth seats S1 to S4 is a seat having the same configuration, and has a seat portion 15 and a backrest portion 16. The intervals X1 to X3 between the sheets S in the front-rear direction are equal. That is, the distance X1 between the hip point P1 of the first sheet S1 and the hip point P2 of the second sheet S2, the distance X2 between the hip point P2 of the second sheet S2 and the hip point P3 of the third sheet S3, and the third sheet The distance X3 between the hip point P3 of S3 and the hip point P4 of the fourth sheet S4 is set equal.

  The distances X1 to X3 in the front-rear direction between the seats S of the present embodiment are set to values smaller than the distances in the front-rear direction of the conventional vehicle seats. For example, while the interval between the conventional sheets is set to 760 mm, the intervals X1 to X3 between the sheets S according to the present embodiment are set to 530 mm. Therefore, the sheets S are approaching in the front-back direction.

  By setting the intervals X1 to X3 in this manner, the seats S partially overlap each other in the front-back direction when the vehicle 10 is viewed from the side in the left-right direction (vehicle width direction). A straight line that passes through the front end S2a of the second sheet S2 (the front surface 15a of the seat portion 15) and extends in the left-right direction is defined as a virtual line L2a. The virtual line L2a intersects with the backrest 16 of the first sheet S1. A straight line that passes through the front end S3a of the third sheet S3 (the front surface 15a of the seat 15) and extends in the left-right direction is defined as a virtual line L3a. The imaginary line L3a intersects the backrest 16 of the second sheet S2. In other words, a straight line that passes through the rear end S2b of the second sheet S2 (the back surface 16a of the backrest 16) and extends in the left-right direction is defined as a virtual line L2b. The imaginary line L2b intersects the seat 15 of the third sheet S3. A straight line that passes through the front end S4a of the fourth sheet S4 (the front surface 15a of the seat portion 15) and extends in the left-right direction is defined as a virtual line L4a. The virtual line L4a intersects the backrest 16 of the third sheet S3.

  Although FIG. 1 shows the inclination angle of each of the backrests 16 with respect to each of the seats 15 of the first to fourth seats S1 to S4 at about 90 degrees, the backrests are set in a state where the occupants A to D are sitting. The relationship between the imaginary lines L2a, L2b, L3a, L4a and the first to fourth sheets S1 to S4 is established even when the seat 16 is tilted forward or backward as much as possible.

  In such an arrangement structure of the seat S, the leg of the occupant B of the second seat S2 is located in the left space of the first seat S1 on the first floor 12a. The leg of the occupant C on the third seat S3 is located in a space on the right side of the second seat S2 on the second floor 12b. The leg of the occupant D of the fourth seat S4 is located in a space on the left side of the third seat S3 on the third floor 12c. That is, in the side view of the vehicle 10, the occupants A to D adjacent in the front-rear direction will sit at positions where the occupants overlap. In FIG. 1B, illustration of the legs of the occupants A to D is omitted.

Next, the operation and effect of the arrangement structure of the sheet S of the present embodiment will be described.
(1) Since the floor 12 is stepped, the seats S1 to S4 cannot move to another floor 12a to 12c adjacent in the front-rear direction. However, in the step-like floor 12 of the present embodiment, the first to fourth sheets S1 to S4 are arranged so as to partially overlap in the front-rear direction in a side view of the vehicle 10, and the sheets S adjacent to each other in the front-rear direction are arranged. Becomes closer. The first to fourth sheets S1 to S4 are alternately arranged in the left-right direction.

  Therefore, the occupant B of the second seat S2 can communicate while seeing the faces of the occupant A of the first seat S1 and the occupant C of the third seat S3, and the occupant of the third seat S3 can communicate with the occupant of the second seat S2. Communication can be performed while looking at the faces of the occupant B and the occupant D on the fourth seat S4. Further, the occupant A of the first seat S1 and the occupant of the fourth seat S4 can easily communicate with each other via the occupant B of the second seat S2 and the occupant C of the third seat S3. As a result, communication between all the occupants can be facilitated.

The above embodiment may be modified as follows.
In the embodiment, the floor 12 is of a three-stage type, but may be changed to a four or more-stage type. For example, in the case of the four-stage type, the space in the rear half of the third floor 12c of the above embodiment is the fourth floor located at a position higher than the third floor 12c. Then, the fourth sheet S4 arranged on the protrusion 14 of the third floor 12c in the above embodiment is arranged on the left side of the fourth floor.

  The distances X1 to X3 in the front-rear direction between the sheets S are 530 mm, but may be changed in a range of 520 to 540 mm. If the sheets S partially overlap each other in the front-rear direction, the intervals X1 to X3 may not be equal.

  Although the first and third sheets S1 and S3 are arranged on the right side of the floor 12 and the second and fourth sheets S2 and S4 are arranged on the left side, they may be arranged left and right reversed. That is, the first and third sheets S1 and S3 may be arranged on the left side of the floor 12, and the second and fourth sheets S2 and S4 may be arranged on the right side.

Next, technical ideas that can be grasped from the above embodiment and other examples will be additionally described below.
