ABSTRACT:
A piece of furniture adapted to support a person in a reclining position includes a base and a mattress support that may be tilted on the base about an axis near the head end of the support. The position of the foot end and the resulting inclination of the supporting surface may be varied by means of a spacer arrangement which includes two hangers pivotally suspended from the mattress support near the foot end. One or two spacer members are secured to the free, lower end portions of the hangers for angular movement about a horizontally extending axis. Stops keep the center of gravity of the spacer or spacers above the last-mentioned axis and limit its angular movement. A friction brake prevents gravity from affecting the angular position of the spacer on the hanger or hangers. When the spacer is in a position in which its center of gravity is vertically aligned with the pivoting axis of the hangers, its downwardly directed face may be engaged by an abutment on the base for angular movement on the hangers when the foot end of the support moves toward the base. Mutual lifting and setting down of the foot end adjusts the spacer arrangement to hold the supporting surface alternatively horizontal or upwardly sloping toward the foot end.
