ABSTRACT:
An armrest adjustment mechanism that comprises a sleeve, a bracket, an adjustment rod and a pair of adjustment blocks, by pulling the pulling portion of the adjustment rod upward will cause withdrawal of the adjustment blocks and further lead to disengagement of the adjustment blocks from the toothed portion of the sleeve, therefore, a height-adjustment of the armrest can be performed, after being adjusted, the adjustment rod is released and will be pulled back to its original position by the return spring, this will cause outward motion of the adjustment blocks and further lead to an engagement of the adjustment blocks with the sleeve, and thus adjustment of the armrest is accomplished.
