ABSTRACT:
A pack frame that is convertible to a chair, having a generally rectangular shaped back section which has fittings that allow a back pack to be attached to it, and a generally rectangular shaped seat section pivotally connected to the back section. The seat section has a rigid frame at the sides and back but not at the front. The back and seat sections have fabric or plastic panels attached to each respectively that form the back and seat of the chair. A front leg section and a rear leg section are each pivotally connected to the seat section. Two adjustable shoulder straps are each attached at one end to a cross member connecting the left front leg and the right front leg at a point below the front of the chair seat and the shoulder straps are connected at the other end to the lower portion of the rear leg member of the chair. When the invention is folded into position for use as a pack frame, retaining clips hold the front and rear legs together. All horizontal cross members are shaped to curve away from the user's body, so they will not come in contact with the user's body when the invention is used as a pack frame, for the comfort of the user. The invention is designed to be used with a padded hip belt and ventilated back pad for the user's comfort.
