Placed on. Here, since the seat cushion 7 of the first seat 3 is disposed to be inclined obliquely forward and downward, even if an occupant tries to sit on the seat cushion 7 of the first seat 3, the seat cushion 7 assumes a forward leaning posture (forward leaning posture). Become. Therefore, it can be clearly recognized that the first sheet 3 is not normally set on the floor surface 19.

  Below, the effect by this embodiment is demonstrated.

(1) A vehicle seat that houses a pair of first and second seats 3 and 5 adjacent to each other in an inverted manner among a plurality of seats arranged side by side along the vehicle longitudinal direction. The first seat 3 disposed on the front side includes a seat cushion 7 and a seat back 11 supported so as to be rotatable with respect to the seat cushion 7, and the front portion of the seat cushion 7 rotates to the floor surface side. It is supported movably. The second seat 5 includes a seat cushion 31 and a seat back 35 that is rotatably supported with respect to the seat cushion 31, and a front portion of the seat cushion 31 is rotatably supported. The floor surface 19 is provided with an erroneous seating prevention member 71. The erroneous seating prevention member 71 folds the first seat 3 backward after the second seat 5 that is folded up in the vertical direction by folding the seat back 35 forward and then tilted backward. The first sheet 3 is configured so as to have a posture different from a normal posture, for example, a forward turning posture (forward leaning posture).

  Therefore, since it can be recognized that the first seat 3 is not in the normal posture when the first seat 3 is tilted on the second seat 5, it is possible to suppress erroneous seating on the first seat 3.

(2) The erroneous seating prevention member 71 is provided so as to protrude upward, and when the second seat 5 that is folded up in the vertical direction by folding the seat back 35 forward is tilted backward. The second sheet 5 is configured to be held in a state of being lifted from the floor surface 19 by a predetermined height.

  Accordingly, when the first seat 3 is tilted backward on the second seat 5, the seat cushion 7 of the first seat 3 is disposed obliquely toward the front obliquely downward, so that the occupant is temporarily in the first seat Even if I sit on 3, I feel uncomfortable because I'm in a leaning position. Therefore, the occupant can clearly recognize that the first seat 3 is not in a normal posture, so that it can be reliably prevented from being seated on the first seat 3 by mistake.
