Abstract
An adjustable backrest has a series of adjustable straps extending across a front opening cavity of a backrest support. The straps are held in a locked, fitted position by a series of buckles at one side of the backrest which engage and lock the straps. Each strap is acted on by a bias arrangement and urges the straps to a drawn position across the front open cavity. This drawn position is an initial setup position that allows fitting of the backrest for a particular user.
