<P>PROBLEM TO BE SOLVED: To provide a seat by which collapse of sitting posture can be reduced over the whole body. <P>SOLUTION: A controller 27 compares an initial period peak position P1 and a peak position P2 after displacement relating to a load peak position P of the pelvis 26A of a passenger 26 sitting on the seat detected by a pelvis displacement detecting sensor 24 arranged in a seat cushion 12 of the seat 10, detects a position 26C of a shoulder blade from load distribution of a thoracic cage 26B of the passenger 26 sitting on the seat detected by a thoracic cage displacement detecting sensor 28 arranged in the upper portion of a seat back 16, and compares an initial period position S1 detected earlier and a position S2 after displacement. Next, the controller 27 moves a sitting portion 22 of the seat cushion 12 in a direction in which displacement between the initial peak position P1 and the peak position P2 after displacement is eliminated and moves the upper portion 16A of the seat back 16 in a direction in which displacement between the initial period position S1 and the position S2 after displacement of the shoulder blade of the passenger 26 sitting on the seat. <P>COPYRIGHT: (C)2009,JPO&INPIT |
