Patent ID: RE39022

Claim:
A backpack unit comprising: a frame of a material selected from one of a metal alloy and a plastic in the form of a folding chair including a U-shaped seat frame pivotally coupled at its ends to ends of a U-shaped back frame through a cross-member, a U-shaped front leg frame pivotally coupled to the seat frame and pivotally coupled at its ends to ends of a U-shaped back leg frame, the frame capable of being folded such that the back frame, the seat frame, the front leg frame, and the back leg frame fold substantially parallel and adjacent to one another; a pair of arm rests pivotally coupled to the back frame and positionally coupled along a first diagonal between the ends of the front leg frame and the back leg frame, the pair of arm rests having a plurality of adjustment positions , a pivotal coupling of the ends of the front leg frame and the back leg frame disposed through one of the plurality of adjustment positions ; at least one support panel to support a user coupled about the back frame and the seat frame and associated with the cross-member; a back rest panel adapted to rest against the back of a wearer of the unit coupled to a back side of the at least one support panel adjacent the seat frame; shoulder straps coupled to the back rest panel; a container having a forward wall panel coupled to the back side of the at least one support panel adjacent the back frame, wherein the position of the arm rests is adjusted by the displacement of the arm rests to a second diagonal, the rotation of the back frame, and the return of the arm rests to the first diagonal, wherein the at least one support panel is at a tension such that with the weight of a user on the support panel about the seat frame, the back frame rotates when the pair of arm rests are displaced to the second diagonal.
