Concept
PackRest is a unique hybrid backpack + chair invention. It is designed for the urban traveler who wants to pack their valuable stuff securely, and get comfortable rest whenever they want it. Simply unzip the bottom of the pack from a sitting or standing position, and a comfortable chair deploys in seconds. This combination chair / backpack is lightweight, sturdy, and super compact – you hardly know it is there. This product can be used anywhere a seat is not available.
What makes this invention unique is the chair is fully concealed within a thin padded “shell”, which is in turn connected to the backpack via a slide mechanism. This allows for the user to carry the chair upon his/her back without the uncomfortable rigidity of rubbing up against the back and shoulders. In this invention, the typical side of a backpack that makes contact with the users’ back, doubles as a padded backrest when the chair is deployed. When the user wants to deploy the chair, a simple action is taken to release the chair seat and legs – folding out from its’ “shell” into a comfortable sitting position.
iterative design sketches
The backpack module would be made from conventional materials and methods that exist in the backpack industry today. The chair module would be made of similar materials and methods that exist in other lightweight portable chairs (such as steel or aluminum tubing, formed metal or plastic, composite core materials, etc.). The criteria of the chair design are that it needs to be: comfortable, thin, compact, lightweight, sturdy, and affordable to produce. Internal to the “shell” of the chair module would also exist a means to deploy the chair, such as an internal frame and/or track which is in turn connected to the chair. The chair module would be connected to the backpack module by conventional means, such as a zipper, clips, Velcro, etc.
