Japanese Utility Model Publication No. 57-32528

However, in the rotating seat device as disclosed in Patent Document 1, although seat arrangement for facilitating communication between adjacent seated persons is somewhat possible, the seated persons further include communication creation. There has been a demand for an arrangement of the seat arrangement and an arrangement of the seat configuration that can be spent in a comfortable environment.
Further, when the rotating seat device is used in a vehicle, there has been a further demand for a seat arrangement and a seat configuration that allow seated persons to enjoy a conversation while simultaneously sharing the scenery seen from the vehicle window.
In particular, it is required to create a more comfortable space in the vehicle by devising the seat arrangement and seat configuration including the front seat and rear seat in preparation for the case where automatic driving of the vehicle is introduced in the near future. It was.

  The present invention has been made in view of the above problems, and an object of the present invention is to devise a seat arrangement and a seat configuration of seats arranged adjacent to each other so that seated persons can spend in a comfortable environment. An object of the present invention is to provide a rotating sheet device that can perform the above-described operation.

According to the rotating seat device of the present invention, the problem is that the seat is provided adjacent to the seat width direction and has a first seat portion and a second seat portion that can be seated, the first seat portion, and the first seat portion. 2 is provided between the seat portion, the first and rotatably connected in the direction toward and away the second sheet portion relative to the seat portion, the second lockable seat seat portion at a position after the rotation The seat includes a seat body including a seat cushion and a seat back, the seat body including a first pad portion provided in the first seat portion, and the second seat portion. A second pad part, and a skin that covers both the first pad part and the second pad part and extends following the rotational movement of the second sheet part, and the second sheet Moves to a predetermined rotational position When the said first sheet portion and the second sheet portion is configured to be continuous in the skin, the epidermis, is solved by, provided in each of said seat cushion and said seat back .

As described above, since the second seat portion is rotatably connected to the first seat portion, and the second seat portion is provided with a seat rotation mechanism that can be locked at an arbitrary position after rotation, The direction of the comfortable seat for the user can be arbitrarily set, and the seat can be locked with the set seating direction.
That is, the seat arrangement of the seating seat and the seat configuration can be devised to realize a rotating seat device that allows seated persons to spend in a comfortable environment.
In the above configuration, when the seating sheet is switched from the normal position where the first seat portion and the second seat portion are close to the rotational position where the second seat portion is separated from the first seat portion, the second seat The epidermis extends following the rotational movement of the seat portion.
Therefore, there is no gap formed between the first seat portion and the second seat portion as in the prior art, and a seating seat in which the first seat portion and the second seat portion are always integrated and continuous with the skin is provided. Can be formed.
As a result, it is possible to always maintain a comfortable distance between the seated persons, and a variety of seat arrangements that expand the imagination of enjoyment are possible.

Further, according to the rotating seat device of the present invention, the problem is that the seating seat is disposed adjacent to the seat width direction and has a first seat portion and a second seat portion that can be seated, the first seat portion, It is provided between the second sheet parts, and the second sheet part can be connected to the first sheet part so as to be rotatable in the approaching and separating directions, and the second sheet part can be locked at a position after the rotation. A seat rotation mechanism, the seating seat having a seat body including a seat cushion and a seat back, the first pad portion provided in the first seat portion, and the second seat portion. At least one of the second pad portions is formed to fill a gap formed between the first pad portion and the second pad portion when the second sheet portion moves to a predetermined rotational position. Towards the gap Having an overhang can pad overhang Te, the pad protruding portion that is provided on each of the seat cushion and the seat back, it is also solved by.
At this time, when the second seat portion moves to a predetermined rotational position, the pad projecting portion may extend while curving along the extending direction of the seating seat.
With the above configuration, when the seating seat is switched from the normal position to the rotation position, the gap portion between the first seat portion and the second seat portion is covered with only the skin, and projects toward the gap portion. Since the pad overhanging portion is provided, the seating comfort of the seat is ensured over the entire surface of the seat.

With the above configuration, the seat rotation mechanism can be assembled with a relatively simple configuration.

At this time, it is preferable that the sheet rotation shaft rotatably connects the first sheet portion to the second sheet portion.
With the above configuration, a wider variety of seat arrangements are possible, and seated persons can spend in a comfortable environment.

At this time, it is preferable that an upper projecting portion that projects outward from the seat rotation axis in a direction intersecting the axial direction is provided in an upper portion of the seat rotation shaft.
With the above configuration, the seated person can spend more comfortably, for example, by using the outer overhanging portion as a table.

At this time, the rotating seat device is a rotating seat device for a vehicle used in a vehicle, and the seat and the seat rotation shaft are slidably connected to the vehicle body floor in the seat front-rear direction or the seat left-right direction. It is preferable that the seat rotation mechanism is provided , and the seat rotation shaft is provided on a slide rail provided in the seat slide mechanism .
With the above configuration, a wider variety of seat arrangements is possible. In particular, a seat arrangement and a seat configuration are possible so that passengers can enjoy a conversation with each other in the vehicle and at the same time share the scenery seen from one of the vehicle windows.

At this time, the seating seat has a first frame portion that is a skeleton of the first seat portion, and a second frame portion that is a skeleton of the second seat portion, and the seat rotation mechanism is One frame part and the second frame part may be connected.
Further, wherein the first frame portion and the second frame portion, the seat front portion, respectively, of the sheet substantially central portion and a seat rear portion, pivotally possible frame connecting the seat rotation axis at least two or more parts It is preferable that the seat rotation shaft is pivotally supported by one selected from the plurality of the frame connecting portions.
With the above configuration, the connection rigidity between the seating seat and the seat rotation mechanism can be improved.
Further, with the above configuration, the assembly position of the seat rotation shaft can be appropriately selected in the front-rear direction of the seat, and a wider variety of seat arrangements is possible.

According to the present invention, it is possible to arbitrarily set the orientation of the seat that is comfortable for the seated persons, and it is possible to lock the seating seat with the set orientation of the seat. That is, the seat arrangement of the seating seat and the seat configuration can be devised to realize a rotating seat device that allows seated persons to spend in a comfortable environment.
Further , according to the present invention, the connection rigidity between the seating seat and the seat rotation mechanism can be improved.
