Abstract
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, and an 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 four-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.
