ABSTRACT:
An adjustment mechanism for armrests includes an armrest plane and a lower plate fastened under the armrest plane. A removable block with smaller length is disposed inside the lower plate. Elastic locating rings are disposed on right and left sides of the removable lock, corresponding to linear locating slot composed of a plurality of curved slots on right and left sides of an inner part of the lower plate. Thus the removable block and the lower plate are moving or located relative to each other. A rectangular slot with a rectangular piece whose width is smaller than that of the rectangular slot is mounted on the removable block. And curved slots for location is arranged on side of the rectangular piece so that the rectangular piece and the rectangular slot move transversely and being located, relative to each other. Moreover, a round slot with a disc therein is arranged on the rectangular piece while a plurality of locating slots is mounted on circumference of the disc so that the rectangular piece and the disc rotate and locate relative to each other. By a fastening member inserting through the disc, the rectangular piece, and the transverse slot on bottom of the removable block, the disc is secured on a fastening seat that is secured on the armrest support. Thereby the armrest has adjustable rotation angle, longitudinal displacement and transverse displacement, relative to the armrest support.
