Abstract
Abstract A portable, knock-down massage chair includes a generally rectangular case having opposed side walls, each provided with an arcuate cutout extending therein from the upper edge thereof. A lid is hinged to a first end wall of the case and openable to gain access to the interior of the case. Stored within the case are a seat member, a leg rest, an arm rest, a chest support, a face cradle, and a brace assembly. The brace assembly comprises a hinged, two-panel assembly stored adjacent to the bottom of the case, and pivotable therefrom out of the top opening to be joined to the lid to form a rigid triangular support assembly. The chest support and the face cradle are slidably supported on the upper panel of the two-panel assembly, and the seat member is secured atop the side walls adjacent to the second end wall of the case. The leg rest is adapted to be secured within the arcuate cutouts of the side walls in a variable angle fashion, and the arm rest is joined to the lid panel. A person receiving a massage is supported on the seat facing the brace assembly, leaning forward with the chest supported by the chest support, the face on the face cradle, the lower legs on the leg rest, and the arms on the arm rest, so that the back, shoulders, neck, hips and arms are well-presented for massage. A stabilizing member is pivotally joined to the bottom of the case to provide lateral stability to the chair in the erected configuration.
