ABSTRACT:
A chair conversion device for a backpack of the type having an external H-bar frame configuration which includes a pair of generally straight tubular side members each of which are pivotally connected adjacent their middle portions to existing side frame members of a provided backpack frame. The tubular side members are swingable through an arcuate range of motion between a first generally upright, storage position to a second open, chair use position. While in the open, chair use position, the bottom end portions of each tubular member form chair rear leg members for the resulting backpack folding chair. A pair of side strap members connect the bottom portions of each chair rear leg member to a bottom portion of the backpack frame to form right and left triangular side supports. An additional transverse strap connects each chair rear leg portion to each other to provide lateral stiffness for the backpack folding chair. A fabric type seat member having side ends folded over and hemmed closed to form loops attaches to and extends between the upper ends of the tubular side members to form the seating surface. In an alternate embodiment the seat member is cut in a trapezoidal configuration and is attached to the upper ends of the tubular side members in a manner such that the long side of a trapezoid forms the leading edge of the seating surface to create a cradle having a greater drop. In another alternate embodiment for the chair conversion device, a single, generally U-shaped tubular frame member is substituted in place of the two tubular side members and transverse strap member arrangement such that a bottom transversely oriented portion of the U-shaped member forms part of the chair rear leg support when the U-shaped frame member is pivoted to the open, chair use position.
