Backpack with a seat

Abstract

A backpack includes a body and a supporting frame. The body includes a plurality of straps, a plurality of pouches, and a compartment. The compartment is communicated with outside via an opening in a bottom thereof. A seat is connected via a connecting member to a side delimiting the compartment. The supporting frame includes a base frame and a back frame pivotally connected with the base frame. The back frame is inserted via the opening into the body and abuts against an inner wall delimiting the compartment, with two distal ends of the back frame protruding out of the body. The base frame includes two distal ends respectively pivotally connected to the distal ends of the back frame.

1 . A backpack comprising: 
 a body including a plurality of straps, a plurality of pouches, and a compartment, the compartment being communicated with outside via an opening in a bottom thereof, a seat being connected via a connecting member to a side delimiting the compartment; and    a supporting frame including a base frame and a back frame pivotally connected with the base frame, the back frame including two distal ends each having two mutually facing L-shaped members and two mutually facing restraining sections, each said L-shaped member including a pivotal hole;    the back frame being inserted via the opening into the body and abutting against an inner wall delimiting the compartment, with the L-shaped members of the distal ends of the back frame protruding out of the body;    the base frame including two distal ends that are respectively located between the L-shaped members of the distal ends of the back frame, each said distal end of the base frame including a pivotal hole aligned with the pivotal holes of the L-shaped members, a pivot extending through the pivotal hole of each said distal end of the base frame and the pivotal holes of each said distal end of the back frame, thereby pivotally connecting the back frame and the base frame;    a distance from each said pivotal hole of the base frame to a tip of an associated one of the distal ends of the base frame being smaller than a distance from an associated pivotal hole of the back frame to an associated one of the restraining section.    
   
   
       2 . The backpack as claimed in  claim 1 , wherein the body includes a plurality of hook and loop fasteners for tying up the base frame when the base frame is in a position parallel to the back frame.
