Abstract
Abstract A briefcase which can be used, when closed, as a backrest for the upper or lower portions of a person''s back, comprises two traylike rigid compartments. The length of the briefcase is greater than its width and, when closed, the briefcase tapers along its length with the taper being selected so that the closed briefcase will comfortably support the back of an individual when the case is rested against the back of a seat. The compartments are hinged together along the length of the briefcase and the locking means and handle for the briefcase are positioned on the opposite long side of the briefcase.

A combined briefcase and back support comprising first and second tray-like compartments, each of the compartments including two short sidewalls and two long sidewalls extending from a bottom panel, the four sidewalls of one of the compartments being perpendicular to the bottom of said one compartment and of equal height, the short sidewalls of the other compartment being unequal in height, the angle between the lower sidewall and the bottom panel of said other compartment being greater than 90.degree. and the angle between the taller sidewall and the bottom panel of said other compartment being less than 90.degree., both angles being chosen so that the short sidewalls of said other compartment are coplanar with the short sidewalls of said one compartment and substantially transverse to the bottom panel of said one compartment when the briefcase is closed, the dimensions of the long sidewalls of said other compartment being selected so that the height of the briefcase, when closed, tapers along the length of the briefcase, with the extent of the taper being chosen to provide comfortable support for the back of an individual by permitting the individual to sit upright when the briefcase is rested on one of its short sides against the back of a seat or the like, hinge means for securing together the compartments permitting rotation of one compartment relative to the other without relative lateral movement, said hinge means being mounted on contiguous long sidewalls of the two compartments, and means for locking the compartments together, said locking means being located on the other long sidewalls of the compartments.
