Patent ID: 8671482

Claim:
An orthopedic device for improving posture while sitting, the orthopedic device comprising: a foundation member comprising: a front portion configured to receive a user's upper legs; a bowl portion configured to receive a user's lower pelvic area, the bowl portion comprising a central portion and a upwardly inclined lateral portion, wherein the lateral portion and the front portion collectively surround the central portion, and the central portion has plural regions of varying flexibility and the lateral portion has plural regions of varying flexibility, and a concave recessed portion extending from a segment of the lateral portion through the central portion to the front portion along a longitudinal midline of the foundation member wherein the concave recessed portion comprises an arcuate segment that is less flexible relative to other regions of the foundation member, wherein the lateral portion has a rear segment surrounded on either side by a lateral segment, said rear and lateral segments of the lateral portion comprising tension regions extending and coupling to the front portion, said tension regions being of higher flexibility than the concave recessed portion, the concave recessed portion having an arcuate underside corresponding to said arcuate segment, wherein the arcuate underside is configured to rotate the orthopedic device on a supporting seating surface between a first position when the user's lower pelvic area is not disposed in the bowl portion, and a second position, rotationally forward of the first position, when the user's lower pelvic area is disposed in the bowl portion, to thereby cause a forward rotational tilting of the user's lower pelvic area into a forward lordotic position after the lower pelvic area is placed in the bowl portion, whereby the bowl portion applies continuous dynamic upwardly and inwardly compressive force for active stabilization support when the lower pelvic area of the user is disposed in the bowl portion.
