  • Patent number: 5839783
    Abstract: A ground-based seat, including a back structure, a seat structure, seat structure support, a foot structure, and foot structure support is described. The back structure includes a top portion, a bottom portion, a front face, and a rear face. The seat structure includes a front portion, a rear portion, a top face and a bottom face, the rear portion of the seat structure being pivotally connected to the bottom portion of the back structure to allow relative rotation of the two structures. The seat structure support extends between the back structure and the seat structure and is positionable for preventing rotation of the seat structure downward and away from the back structure when a person is seated in the seat. The seat structure support may also be configured to allow the seat structure to be positioned substantially parallel to the back structure such that the bottom face of the seat structure lies adjacent the rear face of the back structure.
