Abstract

A self-centering posture seating device is adapted to induce proper posture in seated persons. Specifically, a back support member designed to provide resilient support selectively in the region of the lumbar vertebra of a seated person is conjoined with a posture seating device designed to provide resilient support primarily in the spaced-apart regions corresponding to the ischial tuberosities. The result is a "self-centering" posture seating device which is noticeably more comfortable when properly used than it is when improperly used.

Claims

1. A self-centering posture seating device adapted to induce proper posture in a seated person comprising:

a seat support member for providing regions of resilient seat support to a seated person primarily in the spaced apart regions corresponding to the ischial tuberosities comprising a rigid seat frame and a plurality of stretched resilient bands intersecting within said frame in two regions spaced apart by the distance separating the ischial tuberosities of a seated person; and

conjoined to said seat support member, a back support member for providing a region of resilient back support to a seated person primarily in the region corresponding to the lumbar vertebra comprising a rigid back frame and a plurality of stretched resilient bands intersecting within said frame at the approximate height of the lumbar vertebra of a seated person, said region of resilient back support being centered with respect to said regions of resilient seat support.

2. A seating device according to claim 1 wherein said back support member is rigidly conjoined to said seat support member.

3. A seating device according to claim 1 wherein said back support member is hingeably conjoined to said seat support member.

4. A seating device according to claim 1 including a layer of soft foam material applied over said rigid seat frame and said resilient bands, thereby enhancing the comfort of the seat support.

5. A seating device according to claim 1 including a layer of soft foam applied over said rigid back support member and said resilient bands, thereby enhancing the comfort of the back support.

6. A seating device according to claim 4 including a protective outer cover of material applied around said seat support member.

7. A seating device according to claim 5 including a protective outer cover of material applied around said back support member.

8. A seating device according to claim 1 wherein said rigid seat frame comprises aluminum tubing.

9. A seating device according to claim 1 wherein said rigid back frame comprises aluminum tubing.
