ABSTRACT:
An adjustable arm rest assembly comprises an arm rest; a horizontal plane attitude adjustment, adapted to support the arm rest; a vertical elevation adjustment; and, an arm rest bracket. The vertical elevation adjustment is adapted to be pivotally connected to the horizontal plane attitude adjustment to cooperably facilitate hinged adjustment of the horizontal attitude of the arm rest. The horizontal plane attitude adjustment and the vertical elevation adjustment have co-operable detent and block members adapted to be mutually resiliently secured in ones of a plurality of operably aligned registers corresponding to ones of a selectable plurality of horizontal attitudes for the arm rest. In operation, the detent and block are positioned in mutually resiliently biased, releasably locked interfering relation to thereby releasably fix a relative hingedly interconnected positioning between the horizontal plane adjustment and the vertical elevation adjustment corresponding to a selected horizontal attitude of the arm rest. The arm rest frame bracket is adapted to receive the vertical elevation adjustment in vertically slidably positionable relation thereon, to cooperably facilitate adjustment of the vertical positioning of the arm rest. Respective co-operable locking members on the bracket and the vertical elevation adjustment are adapted to be selectively engaged in resiliently biased mutually interfitting register to thereby releasably interferingly secure the bracket and the vertical elevation adjustment in a predetermined vertically fixed position corresponding to a desired vertical position of the arm rest.
