Chair with Foldable Armrest and Armrest Locking Mechanism

摘要

A chair that facilitates user ingress and egress has a chair support structure and a seat, a backrest, and at least one armrest coupled to the chair support structure. A lower portion of the armrest is coupled to the chair support structure and an upper portion of the armrest is coupled to the lower portion to allow rotation of the upper portion with respect to the lower portion around a horizontal axis that splits the armrest into the two portions. The upper portion can be placed in an upright position above the lower portion and a folded position alongside the lower portion by rotation of the upper portion around the horizontal axis. The upper portion can be locked in the upright position with a locking mechanism that can extend through both the lower portion and the upper portion to prevent rotation of the upper portion around the horizontal axis.
