摘要: An armrest assembly is provided for adjusting an of a seating unit in three degrees motion. The includes angle-adjustment mechanism that allows the to pivot and translate forward, lift enables vertical articulation armrest. bracket with downwardly disposed pin shuttle arcuate slot receive pin. contoured walls form detents restricting movement pin, thereby restraining rotation shuttle, respect bracket, predefined angular positions. rack ride element(s) extending therefrom locking teeth, control bar track(s). upward manual actuation causes track shift laterally retract via interaction between track(s) element(s), respectively.
