ABSTRACT:
A method and means for providing pelvic support to improve posture and relieve lower back pain is provided. The method comprises pressing a convex pillow against the region of the ilia, sacrum, and fifth lumbar vertebra to produce a substantial sacral base angle and to fully oppose any moment tending to cause rotational shifting of the pelvis. Another way to define the invention is a back pillow which may be used in a chair having a seat member, wherein the back pillow includes a convexly shaped support pillow for maintaining the pelvis of the user at a sufficient sacral base angle that substantially the entire weight of the upper portion of the user's body is supported by the seat member. The invention may alternatively be described as a chair comprising a substantially horizontal convex seat for supporting the ischial tuberosities of the occupant in the vicinity of the apex thereof, and a substantially vertical, generally convex support means for supporting the posterior portion of the occupant's pelvis at a sacral base angle of from between 25 and 45 degrees, and so that a gravitational line drawn downwardly from the center of L-3 intersects the anterior one-third of the sacral base.
