Abstract
Abstract A chair for providing support and corrective forces to a patient having scoliotic, lordotic or kyphotic conditions includes parallel side panels with parallel vertical slots on the inner faces and slats extending between the panels. The slats have end fittings which are selectably insertable in the slots with the bottom of each slat resting on the one below so that the slats define a generally curvilinear surface having predetermined curvatures. Devices for holding straps and pads to apply lateral forces in a predetermined manner are also provided. Specific slat structure and full adjustability is provided.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
128 words
An orthopedic chair having a back structure comprising a plurality of elongated slat-like members extending laterally across the chair back, each of said members having a front surface; means on the longitudnal edges of said slat-like members for interconnecting the members in edge-to-edge articulated relationship; first and second support panels at opposite sides of said chair back; and means on the inwardly facing portions of each of said support panels defining a plurality of recesses for receiving the ends of said slat-like members, said members being insertable between said panels with the ends of said members in pairs of said recesses and with said members in edge-to-edge relationship in a selectable pattern of anterior-posterior locations so that the front surfaces of said members define a preselected curvilinear surface.
Claim 2
Dependent Claim
128 words
An orthopedic chair having a back structure comprising a plurality of elongated slat-like members extending laterally across the chair back, each of said members having a front surface; means on the longitudnal edges of said slat-like members for interconnecting the members in edge-to-edge articulated relationship; first and second support panels at opposite sides of said chair back; and means on the inwardly facing portions of each of said support panels defining a plurality of recesses for receiving the ends of said slat-like members, said members being insertable between said panels with the ends of said members in pairs of said recesses and with said members in edge-to-edge relationship in a selectable pattern of anterior-posterior locations so that the front surfaces of said members define a preselected curvilinear surface.
Claim 3
Dependent Claim
28 words
An apparatus according to claim 1 wherein said means defining said plurality of recesses includes a plurality of generally vertically extending parallel slots in each of said panels.
Claim 4
Dependent Claim
33 words
An apparatus according to claim 2 wherein each of said slat-like members includes an extension at each end of the upper edge thereof dimensioned to be received in any one of said slots.
Claim 5
Dependent Claim
95 words
An apparatus according to claim 1 wherein each of said slat-like members further includes a loop means attached to said slat-like member for receiving an end of a strap, said loop means being slidably movable longitudinally on said slat-like member; and means for locking said loop means against longitudinal movement at any of a plurality of positions along said slat-like member, so that a strap can be extended from one of said loop means around the body of a patient occupying the chair and to the same or a seond one of said loop means.
Claim 6
Dependent Claim
45 words
An apparatus according to claim 4 wherein each said loop means is attached to its associated slat-like member on the back surface thereof, and wherein each said slat-like member includes means defining an elongated opening through said slat-like member to permit passage of straps therethrough.
Claim 7
Dependent Claim
28 words
