<P>PROBLEM TO BE SOLVED: To provide a seat having high following property of a cushioning material to the motion of a human body and capable of efficiently damping the vibration to be input from the outside. <P>SOLUTION: In the seat, a torsion bar 112 is used, and a cushioning material of a seat cushion part 150 comprises a first link plate 113 pivotably supported by the torsion bar 112, a second link plate 116 arranged corresponding thereto, and a connection link plate 117 to connecting the first and second link plates, and is supported by a parallel link mechanism. The operational directions of the first link plate 113 and the second link plate 116 are set so as to be substantially matched with the vertical direction along a surface of a seatback part. Thus, the cushioning material performs the rotational motion following the motion of a human body generated by the input of the external vibration, and the relative motion of the human body to the cushioning material is reduced, the resonance peak is lowered, and the vibration absorption characteristic can be enhanced. <P>COPYRIGHT: (C)2008,JPO&INPIT |
