ABSTRACT:
An orthopedic device intended to be contacted by the lower pelvic region of a seated user, the device principally involving a foundation member comprising a central bowl portion serving to receive the lower pelvic region of the seated user. The central bowl portion is integrally connected to a front lip-like portion intended to be contacted by the under thighs of the seated user. The central bowl portion is also bounded by an upwardly inclined rear portion and a pair of upwardly curving side portions closely related with the central bowl portion. The side portions curve upwardly somewhat higher than the central bowl portion and serve to interconnect the rear portion with the front, lip-like portion. The weight of the seated user causes the side portions to move inward and upward so as to cup around the lower pelvic region of the seated user. Each of the side portions may have an enlarged, bead-like member extending along its uppermost edge, with the bead-like members and the side portions forming tension members extending between the front, lip-like portion and the rear portion of the foundation member.
