PROBLEM TO BE SOLVED: To increase the reliability of a six-way manual seat adjuster by moving a front cam operation member from a locked position to a release position against eccentric force of an elastic connection member by a pin-slot connection means. SOLUTION: A rear torsion rod 206 and left side rear seat support arm 230 and a right side rear seat support arm 234 are in a condition in which they can rotate freely, and a torsion eccentric mechanism 238 makes the rear seat support arms 230, 234 eccentric upwards. Consequently, a rear part of a seat cushion is pushed up when an occupant floats his weight from the rear part of the seat cushion merely in this condition. Or, the rear part of the seat cushion can be pushed downwards and adjusted when the occupant applies his weight on the rear part of the seat cushion merely. Here, when an operation lever 352 is released, an elastic connection member makes front and rear cam operation members eccentric to respective locking positions again so that the seat is put to a completely locked position again. |
