US Classification:

29745236, 29745233

Abstract:

A chair back has a shell and a cushion overlying the shell for a patient chair configured to move from a generally upright sitting position to a generally supine position. A patient contact surface is bounded in part by a top edge and an opposing bottom edge, and has resiliently deflectable opposed wing sections extending between the top edge and the bottom edge. A stiff support region is centrally positioned relative to and at least partially recessed from the outer wing sections. The support region is configured to support a patient's spine when the patient chair is positioned in a generally supine position. The opposed wing sections extend laterally outwardly of the support region and are configured to support the arms of the patient when the patient chair is positioned in the generally supine position.

US Classification:

297452360

Abstract:

A back for a patient chair having a back shell with a substantially rigid central S-shaped central portion and laterally extending wing portions which have sufficient flexibility to allow deflection in the direction of the front surface upon imposition of a force. The back consists of a formed back shell, a cushion layer laid thereover and an upholstery layer covering the cushion, with the upholstery layer adhered to the cushion and having edge margins wrapped around the outer edge margins of the cushion. The cushion and upholstery material are secured to the back shell through adhesive applied between the wrapped over edge margin portions of the upholstery material and the back shell.
