Abstract
Abstract A back-rest attachment for a boat seat includes first and second pairs of rods spaced from, and hingeably, connected to one another, and a fabric connected between and attached to the rods of the first pair. The pairs of rods may be pivoted from a first position parallel to one another to a second position at right angles with one another, in which latter position the back-rest attachment may be fastened to a board. In a preferred version of my invention the rods are telescopically collapsible so that the back-rest attachment may be folded into a collapsed position, and wherein the folded fabric may be used as a handle.

A back-rest attachment for a boat seat comprising: first and second rods substantially disposed in a first plane and spaced from, and co-extensive with one another, each of said rods having first and second ends, respectively; a fabric disposed between said first and second rods, and attached thereto; third and fourth rods substantially disposed in a second plane and co-extensive with one another, having third and fourth ends, respectively, said third ends of said third and fourth rods being pivotably attachable to said first ends of said first and second rods, respectively, for said second plane to subtend a range of angles from approximately 0° to 90°; first and second hinges connectable to said first and third, and said second and fourth rods, respectively, having snap-in means for holding said third and fourth rods in stabilized first and second positions, said second plane being substantially parallel with said first plane in said first position, and substantially perpendicular thereto in said second position; and clip means attachable to said third and fourth rods for clipping the back-rest attachment to a board or the like and wherein each of said rods is telescopically collapsible for said backrest attachment to be foldable into a collapsed position, and the folded fabric to be usable as a handle, and further comprising first and second caps attachable to said second ends of said first and second rods, respectively, and wherein each of said rods has selectable extended and collapsed positions and including snap-in means for keeping each of said rods in the selected position of said extended and collapsed positions.
