Foldable chair

A chair that unfolds by a plurality of hinges between an expanded position to a collapsed position to seat a person substantially horizontal in the expanded position while the chair is positioned on an angled surface, comprising:

• a back assembly having a back frame and a back covering which partially covers the back frame, the back frame including opposing back side members which are coupled together by a back cross member;
• a seat assembly secured to a seat hinge of the plurality of hinges, the seat hinge pivotally coupling the seat assembly to the back assembly for relative movement of the back assembly and the seat assembly between the collapsed position and the expanded position, the seat assembly having a seat frame and a seat adjustment assembly, the seat frame including opposing seat side members, the seat adjustment assembly includes a seat track which is integrally disposed within the back side members;
• a leg assembly secured to a leg hinge of the plurality of hinges, the leg hinge pivotally coupling the leg assembly to the seat assembly for relative movement of the leg assembly and the seat assembly between the collapsed position and the expanded position, the leg assembly having a leg frame which includes opposing leg side members;
• and
• a collapsible seat which is removably coupled to the seat assembly, the seat having a proximal end, a distal end, a body positioned between the proximal end and the distal end, the proximal end connecting with the adjustment pin, the distal end connecting with the seat attachment such that the adjustment pin removably engages with the seat track and the seat attachment connects with the seat frame to position the body of the seat in a substantially horizontal position with respect to the angled surface,
• whereby, in the collapsed position, the leg assembly rotates around the leg hinge to be folded within the seat assembly and the seat assembly rotates around the seat hinge to be folded within the back assembly.

A chair that folds by a plurality of hinges between an expanded position and a collapsed position to seat a person substantially horizontal while the chair is positioned on an angled surface, comprising:

• a back assembly having a back frame and a back covering which partially covers the back frame, the back frame including opposing back side members, each back side member having a first back end and a second back end;
• a seat assembly secured to a seat hinge of the plurality of hinges, the seat hinge pivotally coupling the seat assembly to the back assembly, the seat assembly having a seat adjustment assembly, the seat adjustment assembly includes a seat track which is integrally disposed within the back side members, the seat track having a plurality of seat adjustment positions;
• and
• a collapsible seat which is removably coupled to the seat assembly, the collapsible seat having a proximal end, a distal end, a body positioned between the proximal end and the distal end, an adjustment pin and a seat attachment wherein the proximal end connecting with the adjustment pin, the distal end connecting with the seat attachment wherein the adjustment pin removably engages with at least one of the plurality of seat adjustment positions of the seat track such that the engaged adjustment pin with the seat track positions the body of the seat in a horizontal position with respect to the angled surface and such that the adjustable pin is rotatable within the respective seat adjustment position such that the rotation of the adjustment pin adjusts tension of the body of seat.
