  When the armrest 40 is in the position as described above, in order for the occupant S to actually use the armrest 40 (or put an elbow on the armrest 40), it may be necessary to move the body toward the door trim 10 side. It is understood as a thing.

  The present invention has been made in consideration of the above problems, and an object of the present invention is to provide a seat structure and a vehicle that make it easy for an occupant to use an armrest.

The sheet structure according to the present invention is
An armrest attached to the door trim,
And a seat cushion attached to the vehicle body,
When the door is in a closed state, a portion of the armrest is positioned directly above the seat cushion.

  According to the present invention, when the door is closed, a portion of the armrest is positioned directly above the seat cushion. For this reason, it is possible to make the armrest easy to use without the occupant getting close to the door.

  The armrest is located above the upper surface of the seat cushion and is an upper convex portion projecting inward from the door trim, and a lower side recessed toward the door trim side relative to the upper convex portion on the side of the seat cushion It may have a side wall portion. Further, a storage space into which a part of the seat cushion enters when the door is in a closed state may be formed on the lower side of the upper convex portion and on the inner side of the lower side wall portion. This makes it easy to position a part of the armrest directly above the seat cushion when the door is closed.

  When the door is in a closed state, the lower surface of the upper protrusion may be in contact with the upper surface of the seat cushion, or the vertical distance between the lower surface of the upper protrusion and the upper surface of the seat cushion may be less than 2 centimeters . As a result, it appears to the eyes of the occupant that the upper surface of the seat cushion and the inner side surface of the upper convex portion are continuous. For this reason, it becomes possible to give a sense of unity to a seat cushion and an armrest.

  When the door is in the closed state, the side surface of the lower side wall portion is in contact with the side surface of the seat cushion, or the side width direction of the lower side wall portion is 3 It may be less than a centimeter. This makes it possible to further strengthen the sense of unity between the seat cushion and the armrest.

  The seat cushion may project in the opening direction of the door more than the seat back. As a result, when the vehicle is stopped and the door is open, the occupant can sit in a manner such that the legs extend outward from the opening of the door.

  The front portion of the seat cushion may be inclined downward toward the front. Further, the rear portion of the seat cushion may be inclined downward toward the rear. Thereby, since the shape becomes the same before and after the seat cushion, it is possible to improve the impression when the door is opened.

  A cushioning material may be disposed on a side surface inside the vehicle of the armrest. This makes it easy for the occupant to rest his / her arm on the upper surface of the armrest while placing the body against the side surface of the armrest on the inner side of the vehicle.

  A skin material made of the same material as the seat cushion may be disposed on a side surface of the armrest on the vehicle inner side. As a result, by unifying the appearance of the seat cushion and the armrest, it becomes easy to feel a sense of unity between them.

  A vehicle according to the present invention includes the seat structure.

  According to the present invention, the occupant can easily use the armrest.
