Abstract
An adjustable attachment has been developed which can be used in combination with an auxiliary backrest to suspend the backrest from a fixed backrest normally found on a chair or wheelchair. The support structure includes an elongate receiver and a hanger. The receiver extends longitudinally and is normally fixed in a vertical position to the auxiliary backrest and defines a plurality of openings spaced apart along the length of the receiver to form a row of openings. The hanger is shaped to fit in any one of the receiver openings and the receiver has an outer part so that in use the hanger can be engaged through a selected one of the openings. The hanger then extends along the length of the receiver and the outer part can be engaged downwardly over an upper edge of a fixed backrest or other support. The structure is also disclosed in combination with an adjustable auxiliary backrest having a resiliently deformable vertical spine and ribs having forwardly and outwardly end portions to give lateral support to the user.
