Further, since the adjacent polygon parts 50 and 60 are connected by the rotation shaft 70 in a state where the comb-shaped connecting ends 53 and 63 are meshed with each other, the movable range of the polygon parts 50 and 60 becomes large. ..

As shown in FIG. 6, the sheet main body portion 12 is developed into a single sheet shape while maintaining a connected state between adjacent polygon surfaces 20. As a result, even if the seat surface 22 and the backrest surface 24 have complicated surface shapes, the seat body portion 12 can be deformed into a desired shape by a simple operation that does not involve disassembly of the parts.

<Assembly work>
At the time of assembling the seat device 10, the occupant bends and forms the seat body 12 which is a single sheet shape. As shown in FIG. 3, even if the seat surface 22 and the backrest surface 24 have complicated surface shapes, the seat body portion 12 can be deformed into a desired shape by a simple operation that does not involve assembling parts. ..

After that, the occupant brings the back surface 18 of the seat body 12 into contact with the receiving surface 40 of the support plate 14, and then performs the reverse procedure of the deployment operation described above. As a result, the assembly work of the seat device 10 is completed.

[Effect of sheet device 10]

[4] The sheet main body portion 12 is configured to be expandable into a single sheet shape while maintaining a connected state between adjacent polygon surfaces 20.

In this way, the seat surface 22 and the backrest surface 24 are formed by connecting a plurality of polygon surfaces 20 arranged along the two directions, respectively, so that a complicated surface shape that enhances the adhesion to the occupant can be obtained. It can be expressed and the seating comfort of the occupant can be improved. Further, since the combination expression of the polygon surface 20 creates an artificial and industrial aesthetic feeling, the design of the entire sheet device 10 is improved.

Further, since the seat body portion 12 is configured to be expandable into a single sheet shape while maintaining the connected state between the adjacent polygon surfaces 20, the seat surface 22 and the backrest surface 24 have a complicated surface shape. However, the seat body 12 can be deformed into a desired shape by a simple operation that does not involve disassembling and assembling the parts. As a result, when mounted on a moving body, it is possible to improve the sitting comfort of the occupant, the workability of assembly / deployment, and the design.

Further, the seat device 10 further includes a support plate 14 (support portion) that supports the seat body portion 12 bent so as to form an open curved surface from below, and the seat body portion 12 is higher than the support plate 14. It may be removable along the longitudinal direction. As a result, the workability of assembling and deploying the seat device 10 is further improved. Further, there is an advantage that the seat body portion 12 in use can be prevented from coming off from the support plate 14.

Further, the sheet main body portion 12 may be configured by rotatably connecting polygon parts 50 and 60 forming a polygon surface 20 to each other. As a result, workability when deforming the seat body portion 12 is improved, and reproducibility of the deformed state is improved.

Further, the adjacent polygonal parts 50 and 60 may be connected by the rotating shaft 70 in a state where the comb-shaped connecting ends 53 and 63 are meshed with each other. As a result, the movable range between the polygon parts 50 and 60 is increased.

Further, each polygon component 50 (60) may be formed by laminating a plurality of plate members 51, 52 (61, 62). As a result, the rigidity of the seat device 10 as a whole is increased.
