Abstract

A seat comprises a plurality of air mats arranged inside a seat cushion and a seat back. The contour of each of the air mats is automatically varied by a pump and a valve. The fatigue level of a seat occupant is calculated based on a fatigue-indicative parameter weighted in accordance with the running state of a vehicle and the working state of accessories and control gear. The pump and the valves are operated to vary the contour of the air mats when the fatigue level becomes greater than a predetermined value.
