ABSTRACT:
In a device for adjusting the support pressure of the passenger's thighs by raising or lowering a thigh support part in a seat cushion, a lock mechanism is mounted both in a seat frame and the thigh support pipe which rotates in the up and down directions of said seat frame. The lock mechanism consists of a lock piece pivotally fixed to a rotating shaft disposed horizontally in the thigh support pipe, a stopper which engages with the lock piece mounted rotatably free to the thigh support pipe and a lock release lever which releases a locking state by pushing said stopper in the direction opposite to its engaging direction.
