Chair with variable positioning and support

Abstract

An adjustable chair frame with a back and seating surfaces that flex to conform to the shape, weight and movement of an occupant is disclosed. The chair form and proportions provide for a recumbent position that disperses the weight of the occupant more evenly, thereby reducing external and internal physiological point loading. The form also provides ergonomic articulation to minimize internal physiological stresses such as neck/back vertebral compression. Eccentric connections driven by a motor assembly allow positioning adjustment of the components of the chair. Additionally, an air pump assembly may be included to automatically adjust one or more air bladders provided on the interior of the chair frame.

1 . A flexible and adjustable chair comprising:
 a structural frame including a side rail, a pair of front and back structural rings, cross support members, and bottom structural frame member;   a headrest assembly adjustably connected to the structural frame;   a tensioned and flexible sub-structure supporting a seating area;   adjustable eccentric connections between one or more of the components of the chair; and   one or more inflatable air bladders provided on an interior of the structural frame, the one or more inflatable air bladders providing internal support.
