ABSTRACT:
A reclining chair (10) having a seat (12), backrest (14), side supports (16) and a reclining mechanism which includes a backrest bracket (34) rigidly affixed to the backrest (14) and pivotably mounted to a side support bracket (18), the side support bracket (18) being rigidly affixed to a side support (16). A seat support bracket (30) is rigidly affixed to the seat (12) and pivotably mounted to a side support bracket (18). A coupler link (40) has one end pivotably connected to the backrest bracket (34) and a second end pivotably connected to the seat support bracket (30). The axis of rotation of the backrest (14) is located so as to pass approximately through the hips of a chair occupant. Further, the linkages are so selected and arranged that the reclining motion and return motion take place by a horizontal translation of the center of gravity of the occupant to minimize the effort required to operate the reclining mechanism through its range of movement.
