Zusammenfassung:PROBLEM TO BE SOLVED: To enable a seat to keep a proper, comfortable seating position even if the angle of its back part is altered. SOLUTION: A seat part 4 is held in position by means of inequilateral tetramerous links 19 such that it can be raised/lowered and also be tilted in a lowering position with its rear part tilting downward. The seat part 4 is composed so as to be actuated by raising-/lowering-drive expansion actuator 2. The back part 5 is pivotally attached to the rear end of the seat part 4 so as to be tiltable. The back part 5 can independently be tilted by a tilting- drive expansion actuator 3.
