ABSTRACT:
A seat is mounted on right and left slide rails slidable on right and left guide rails so that the position of the seat is adjustable back and forth. Right and left lock mechanisms are mounted on the right and left slide rails, respectively, for locking a relative movement between a right or left pair of the slide and guide rails. A handle bar is connected with the left lock mechanism, for example, and extends forwardly so that the left lock mechanism is unlocked with the handle bar. The motion of the handle bar for unlocking the left lock mechanism is transmitted through a release wire and link mechanism to the right lock mechanism to unlock the right lock mechanism together. The release wire extends from the handle bar adjacent the left slide rail to the right slide rail near the front of the seat. The link means extends backwardly along the right slide rail from the end of the release wire to the right lock mechanism. The link means makes it possible to displace the position of the right end of the release wire toward the front of the seat.
