ABSTRACT:
A seat frame with an integrally built-in slide rail mechanism, in which a seat-frame side member and a member corresponding to the upper member of the slide rail are integrally combined into a frame structure defining an internal space of closed section, and principal parts of the slide rail mechanism, including a stopper actuated by a handle through a lever, are disposed in this internal space. A slide-rail lower member disposed beneath the corresponding member is formed with locking slots with which engaging lugs of the stopper are engageable so that the seat frame can be locked in any desired position and unlocked to make longitudinal movement along the slide rails.
