  • Patent number: 4775182
    Abstract: The chair of the present invention comprises a foldable frame of metal or other rigid material, comprising a fabric or plastic seat rest supported between a pair of tubes or rods, to the ends of which are hingedly connected a pair of telescoping tubular back supports, which, in open position extend upward, supporting between them in taut relation a backrest, also of fabric or plastic, which is further supported by a pair of X-pivoted braces and other braces connected to the telescoping tubular supports. Four stub legs support the seat rest in open position. A particular feature of the invention is that it is readily folded into an elongated configuration of narrow width, which may be fitted into a tube, by first folding the back and seat together, and telescopically extending the back supports, which simultaneously causes the X-pivoted braces and other braces to rotate into approximately parallel relation with the back supports.
