BACKGROUND OF THE INVENTION
This invention relates to improvements in baekpacks and baek raeks and in particular to a :folding frame raek and baekpaek whieh is eonvertible to a ehair when unfoldecl.
Most modern backpaeks have a frame which typically consists of shaped tubing with an attaehed paek. The assembly is then carried by the user by means of adjsutable staps and, often, an adjustable waste belt. The frame may be flexible or rigid but is primarily intended for the sole purpose of carrying a load while the user is walking. These baekpacks leave the user to his own devices when a rest is required and often the user is required to place the paek on the ground in condition where it may beeome damp and/or soiled while the user may also beeome damp or soiled while sitting.
Previous folding baekpacks are known such as shown in:~S

~lso known in the prior art are folcling chairs such as lawn chairs of various configurations. It is known to add a paek structure to sueh folding ehairs so as to form a baekpack.
In none of the foregoing, however, was there provided an inexpensive folding ehair backpack or back raek eombination wherein the user's baek supports the frame by means of flexible material rather than elements of the frame whether padded or not.
The present invention provides a simple baekpaek or back raek and folding ehair combination which overcomes the problems of the prior art and is, at the same time, easy to manfae-ture and ship.
