Abstract
A seat in which a cushioning member has a high following ability to a human body motion and which can efficiently damp a vibration inputted from the outside is provided. The seat is constituted to use a torsion barand to support a cushioning member of a seat cushion sectionby a parallel link mechanism having a first link platepivotally supported by the torsion bar, a second link platedisposed in correspondence with the first link plate, and a connection link plateconnecting the first link plateand the second link plate, and operational directions of the first link plateand the second link plateare set to almost coincide with a vertical direction along a surface of a seat back section. Thus, a rotational motion following a human body motion generated by an external vibration input is performed, so that a relative motion between a human body and the cushioning member is small and a resonance peak is lowered, whereby a vibration absorption characteristic can be improved.
