Abstract
Official abstract text for this publication.
An aircraft armrest may incorporate a rail roller linkage. The roller linkage may include an armrest plate, a rail attached to an aircraft seat assembly, a top roller link, and a bottom roller link. The top roller link may have a threaded upper adjustment cylinder, a pivot joint, and a pair of grooved rollers diagonally disposed on either side of the pivot. The bottom roller link may have an unthreaded lower adjustment cylinder, a pivot joint, and a pair of grooved rollers diagonally disposed on either side of the pivot. The grooved rollers may mesh with the rail. The roller linkage may include a roller adjustment screw, having a threaded portion, and extending through both of the adjustment cylinders. A compression spring may bias the roller link around the rail and may be disposed between the top roller link and the bottom roller link and surrounding the roller adjustment screw.
First claim
Opening claim text (preview).
What is claimed is: 1. An aircraft armrest rail roller linkage apparatus comprising: (a) an armrest plate for attaching to an armrest assembly; (b) a rail attached to an aircraft seat assembly; (c) a top roller link, attached to the armrest plate, having an upper adjustment cylinder that is threaded and also having a pivot joint and a pair of grooved rollers diagonally disposed on either side of the pivot, the grooves meshing with the rail; (d) a bottom roller link attached to the armrest plate, having a lower adjustment cylinder that is unthreaded and also having a pivot joint and a pair of grooved rollers diagonally disposed on either side of the pivot, the grooves meshing with the rail; (e) a roller adjustment screw, having a threaded portion, and extending through both the upper and the lower adjustment cylinders, the threaded portion of the roller adjustment screw meshing with the threaded portion of the upper adjustment cylinder; (f) a compression spring, biasing the top and bottom roller links around the rail, disposed between the top roller link and the bottom roller link and surrounding the roller adjustment screw; and (f) wherein the respective pivot joints of the top roller link and the bottom roller link are positioned on opposite sides of the rail.
