ADJUSTABLE ARMREST ABSTRACT An armrest assembly is self-adjusting as to height in response solely to the rotation of a connecting support lever to which an armrest is mounted. The adjustment mechanism includes a spring biased latch pawl engaging a ratchet wheel inside the support lever. The spring holds the pawl engaged to the ratchet when the support lever is rotated in one direction; the spring holds the ratchet wheel and pawl in disengagement when it is rotated in the other direction. The ratchet remains fixed relative to the movement of the armrest portion and the support lever. An adjustable cable running from the ratchet wheel through the support lever and into the armrest portion maintains the armrest portion in a horizontal position and provides adjustment above and below the horizontal.
