Seat device

A method for manufacturing a seat device, wherein the seat device has a seat part on which a seated person is seated and a vibration imparting device configured to impart vibrations to the seated person, the seat part has a frame, a pad material and an overhang portion, the pad material has a recessed part formed on the pad material, the method comprising:

• disposing the pad material at an upper position of the frame, and
• attaching the vibration imparting device to the seat part so that the vibration imparting device is disposed at a position facing the recessed part in a thickness direction of the pad material and is disposed at a back position of the overhang portion,
• wherein the pad material has a through hole that penetrates the pad material in the thickness direction of the pad material, and
• the vibration imparting device is disposed between the overhang portion and the through hole in a front to back direction of the seat part.

A seat device comprising:

• a seat part on which a seated person is seated;
• and
• a vibration imparting device configured to impart vibrations to the seated person, wherein
• the seat part has a frame and a pad material disposed at an upper position of the frame,
• the pad material has a recessed part formed on the pad material,
• the vibration imparting device is disposed at a position facing the recessed part in a thickness direction of the pad material,
• the seat part has an overhang portion formed on a front end portion of the seat part,
• the vibration imparting device is disposed at a back position of the overhang portion,
• the pad material has a pad rear portion disposed at a back position of the vibration imparting device, and
• a vertical thickness of the vibration imparting device is smaller than a vertical thickness of the pad rear portion.
