ABSTRACT:
A seat comprises a plurality of air mats which are arranged inside a seat cushion and a seat back. The contour of each of the air mats is automatically variable by a pump and a valve according to an automatic mode of variation. When a manual switch is turned on to control the valve, an initial mode of variation is altered by incorporating a manual command so as to determine a second mode of variation. The seat contour is then varied according to the second mode.
