Beschreibung
Zusammenfassung:	The present invention relates to a chair capable of preventing backache, including a posture detecting unit for detecting the posture of a seated person on the chair; a control unit for determining whether the seated person suffers from backache based on the posture of the person detected by the posture detecting unit; and a vibration generating unit for generating vibration to the chair under the control of the control unit. In the case where the person is seated in a bad sitting posture to cause the backache, the chair is vibrated up and down to prevent the backache. Also, since the chair is vertically vibrated by forming an electromagnetic field and using the interaction of a permanent magnet, the vertical vibration width can be precisely controlled according to a bodily state of the seated person.
