For example, each skin piece can be formed by sewing and connecting a plurality of skin pieces, and can also be configured with a single-piece face material. In addition, one end of the first skin piece can be individually hooked to the seat frame (side frame, wire material or the like), or can be hooked to a wire embedded in the seat pad.

  Further, in the second skin piece, a plurality of folds can be formed in parallel in an appropriate direction such as the sheet width direction, and the cross-sectional shapes of the plurality of folds can be appropriately changed. It can also be arranged. Further, the second skin piece can be formed of a material that is easily expanded and contracted as compared to the first skin piece and can be easily deformed. Further, the first skin piece can be easily deformed by making the locking member easy to expand and contract, and the first skin piece can be easily deformed by connecting it to the side skin piece through the face material that is easy to expand and contract. You can also

  Further, in the present embodiment, the configuration (shape, size, formation position and number of formation of each part, etc.) of the seat pads 4P and 6P is exemplified, but the configuration of the seat pads is not limited. For example, the top plate main portion can be formed in a series without forming the third groove portion. Further, at least one of the first groove and the second groove can be formed in the seat pad. Similarly, the configurations of the seat frames 4F and 6F can be changed as appropriate. And the structure of a massage unit can also be changed suitably, for example, the shape and the number of formation of a massage part can be changed suitably according to a sheet | seat structure.

  Moreover, although the massage unit was illustrated as a movable member in a present Example, the top-plate main part should just be a member which can be relatively moved. For example, various members, such as a lumbar support, can be illustrated as a movable member. In addition, the movable member can be moved in an appropriate direction such as the seat vertical direction, the seat lateral direction, and the seat longitudinal direction. For example, in the seat back, the movable member may be moved in the vertical direction of the sheet in a state where the top plate side portion is pressed.

  Further, in the present embodiment, the seat cushion 4 and the seat back 6 are exclusively described as an example, but the configuration of the present embodiment can be applied to various seat constituent members such as a headrest. Further, the configuration of the present embodiment can be applied to all types of seats for vehicles such as vehicles, aircraft, and trains.
