Abstract
In a chair having a base, a seat, a backrest, and a tilt control mechanism, a horizontal adjustment mechanism is provided for allowing fore and aft shifting movement of the seat relative to the backrest. The tilt control mechanism typically includes a pair of rails or other mounting structure by which the control mechanism is normally fastened to the seat. The rails present a pair of laterally spaced longitudinally extending edges and a plurality of mounting holes arranged in a predetermined pattern. The horizontal adjustment mechanism includes a seat mounting assembly provided with a pair of laterally spaced guides adapted to engage the edges of the rails to support the seat mounting assembly for sliding movement on the control mechanism. The seat mounting assembly presents at least one plurality of mounting holes by which it can be fastened to the seat, and these mounting holes of the seat mounting assembly are arranged in the same pattern as the holes in the rails so that the horizontal adjustment mechanism can be employed on the chair without requiring modification or added expense. Likewise, by employing the rails of the tilt control mechanism to support the guides of the seat mounting assembly, a low profile is presented that reduces the overall height of the seat above the ground.
