ABSTRACT:
A seat adjustment mechanism principally for vehicle seats comprises a frame connected to a base by front and rear linkages. A mechanism is provided that is operated by a handle with a first movement of the handle unlocking the front linkages to allow the tilt of the frame to be adjusted relative to the base and continued movement of the handle unlocking both linkages to allow the height of the frame to be adjusted relative to the base. This is achieved by successively pivoting lever arms that successively unlock the pairs of links.
