POSITION ADJUSTABLE ARMREST ASSEMBLIES FOR PASSENGER SEATS

An armrest assembly for an aircraft passenger seat including a base, a first arm having a first end pivotally attached to the base, a second arm having a first end pivotally attached to the base, andan arm support element pivotally connected to a second end of the first arm and pivotally connected to a second end of the second arm. An assist device applies force to bias the arm support element from a first position toward a second position higher than the first position. The base, the arm support element, the first arm, and the second arm operate together as a 4-bar linkage system. Upon actuation of a user-actuatable release device, the arm support element can be moved from the first position to the second position with force assistance from the assist device. 一种用于飞机乘客座椅的扶手组件包括：基座、具有枢转地附接到基座的第一端的第一臂、具有可枢转附接到基座的第一端的第二臂，以及枢转地连接到第一臂的第二端并且枢转地连接到第二臂的第二端的臂支撑元件。辅助装置施加力使臂支撑元件从第一位置朝向高于第一位置的第二位置偏置。所述基座、臂支撑元件、第一臂和第二臂作为四连杆系统一起操作。在能够由用户致动的释放装置被致动时，臂支撑元件能够在辅助装置的力辅助下从第一位置移动到第二位置。
