Abstract
Abstract An orthopedic reclining chair is reclinable to a position in which the body of the occupant is substantially inverted, the occupant being retained in the chair by means of a lap belt engaging the upper surface of the thighs whereby to support the weight of the head and torso through the hip joints so as to apply traction to the spine of the occupant. Preferably the heating unit comprises an integral backrest and seat, together with a support for the lower portions of the legs, the seating unit being rockably suspended from a frame relative to which it may be pulled rearwardly from an equilibrium semi-reclining position to its substantially inverted position.
