ABSTRACT:
An orthopedic back support for displacing a person's weight from the lower area of the spine by providing support for the upper torso and for use with a chair or seat having a seat base and a seat back. A flexible fabric cross piece is connected between vertical axillary support members to provide back support. The cross piece may include vertical channels or sleeves at opposite sides to receive and support the vertical members. The entire unit is portable and when in use facilitates unobtrusive intermittent use and easy ingress and egress from the seat to relieve discomfort after long periods of use. A rib band may be attached to the flexible fabric by means of hook and loop fabric strips such as Velcro to form a detachable connection. A hook strip is disposed on the back of the rib band and is adapted to cooperate with a mating soft loop strip on the forward side of the flexible fabric member which supports the user in a seated position by the combined action of the flexible fabric and rib band. Alternatively, the rib band may be used separate from flexible fabric back support in which case the detachable connection is made between the rib band and the seat back. The connections are such that the force of connection is greater in sheer than in tension.
