ABSTRACT:
An armrest mounting assembly (20) for mounting an inverted, U-shaped, armrest assembly (14) to a wheelchair having a frame (10). The mounting assembly (20) includes a body (22) which is formed to receive an end of the armrest post portions (17). Releasable fasteners (29) couple the body (22) of the armrest mounting block to the wheelchair frame (10). The mounting assembly (20) includes a mounting groove (28) defined by the body (22) proximate a frame engaging surface (24) of the body (22). The groove (28) is formed and dimensioned to slidably receive an enlarged head (36) of the fastener (29) for movement of the mounting block (20) through a plurality of positions along the wheelchair frame member (18) when the fastener (29) is not tightened. This movement permits alignment between the armrest post portion (17) and mounting body (22). Further, the groove (28) retains the head (36) of the fastener ( 29) against rotation for tightening of the fastener (29) to secure the mounting block (20) in alignment with the spaced apart armrest post portions.
