ABSTRACT:
A collapsible chair has an adjustable in-use position and a folded transport position. A seat is supported by opposite pairs of front and rear legs pivoted together at their upper ends. Opposed pairs of outwardly extending front and rear retainer pins on the seat engage front and rear tracks on the legs to support the seat and also to enable the seat and legs to be folded together for transport. A reclinable back rest is hingedly connected to the seat, and arm rests extend between the back rest and the upper ends of the front legs. The connection of the arm rests to the front legs is adjustable which adjusts the inclination of the reclinable back rest. Drum shaped wheels are rotatably mounted to and between the rear legs at their lower ends. The front and rear legs are spread apart at their lower ends when the collapsible chair is in use. Conversely, in the transport position the legs and seat are folded together and the drum shaped wheels engage the ground. The seat may include a separate central portion which swings outwardly and away from the seat to form a cargo transport when the collapsible chair is in its transport position.
