A single-post, height-adjustable and removable armrest apparatus (30) for a wheelchair having wheelchair frame (21). The armrest apparatus includes a base (31) formed for mounting to the wheelchair frame and an arm support assembly (32) having a height-adjustable armrest post (33). Interdisposed between the base and the support assembly is an elongated mounting assembly (34). A locking mechanism (37) is movably mounted to a mounting end (35) of the mounting assembly between a locked condition and a unlocked condition. In the locked condition, the mounting end is locked to the base member, while in the unlocked condition, the mounting end is released from the base. A securing mechanism (40) is movably mounted to an engaging end (36) of the mounting assembly between a secured condition and an unsecured condition. In the secured condition, the armrest post is locked to the mounting assembly, while in the unsecured condition, height adjusting movement of the armrest post is permitted relative to the engaging end. The armrest apparatus further includes a manually engageable latch assembly (41) operably engaging both the locking mechanism and the securing mechanism. The latch assembly moves between a selected one of: 1) the locking mechanism to move the locking mechanism from the locked condition to the unlocked condition, while the securing mechanism is retained in the secured condition; and 2) the securing mechanism to move the securing mechanism from the secured condition to the unsecured condition, while the locking mechanism is retained in the locked condition. |
