Abstract:
An adjustable seating system which includes at least a seat and a back and which is adaptable to provide specialized postural control for a person using the seating system by supporting specific anatomical areas of that person, wherein the seating system includes first, second and third pelvic stabilization components, comprising:(1) a raised barrier that extends transversely of the seat at a distance spaced forwardly of a rear end of the seat for co-operation with the ischial tuberosities of the pelvis, to control rotation of the pelvis beneath the person; (2) a pad extending transversely of the back at a location to provide resistance to the posterior superior iliac spine of the pelvis; and, (3) means extending transversely of and spaced above the seat in the vicinity of the upper thigh area of the person for controlling anterior movement of the pelvis, said means comprising two semi-elliptical pads that are suspended above the seat and forwardly of the back by a cantilever mechanism that allows the pads to be moved between operative positions in which they contact the pelvic area of a seated person from opposite sides, and inoperative positions in which the pads are retracted to allow the person to enter and leave the seat; wherein the cantilever mechanism comprises respective brackets at each side of the seat, the brackets being coupled to the seat for adjustment longitudinally thereof and being adjustable height-wise with respect to the seat; a pair of shafts each supporting a said pad for adjustable sliding movement longitudinally of the shaft and turning movement about the shaft; and means coupling the shafts, to the respective brackets for turning between respective generally upright positions and generally horizontal positions corresponding respectively to said inoperative positions and operative positions of the pads.
