- raising and lowering means for raising and lowering said seat with respect to said base frame;
- a chair back which is pivotably associated with said seat;
- and
- a chair back support means, associated with said base frame, for supporting said chair back,
- wherein, when said seat is raised with respect to said base frame the chair back is rotated rearwardly from an inclined position to a substantially horizontal position, said support means being operable for supporting said chair back when said chair back is in said substantially horizontal portion.
A chair which is convertible to a table, comprising:
- a base frame;
- an elongate first threaded member having a longitudinal axis, said first threaded member being mounted in said base frame such that each end of said first threaded member is held at a fixed location with respect to said base frame but said first threaded member can be rotated with respect to said base frame about said longitudinal axis;
- a seat structure;
- a second threaded member mounted in said seat structure, said second threaded member being threadedly associatable with said first threaded member such that, when said second threaded member is threadedly associated with said first threaded member and said first threaded member is rotated about said longitudinal axis, said seat structure moves with respect to said base frame along said longitudinal axis;
- rotating means for rotating said first threaded member about said longitudinal axis;
- a chair back which is pivotably associated with said seat structure and;
- a chair back support means, associated with said base frame, for supporting said chair back, said chair back support means being operable for supporting said chair back at at least one reclining angle,
