Armrest and armrest mechanism

Abstract

An armchair mechanism that includes a toothed pawl and cam mechanism which allows the armrest to rotate in an arc greater than 90 degrees and into a first angular position. The armchair mechanism further includes a lockout member which locks the armrest in a design position and a stowed position. During a first angular portion of movement along the rotation arc, the armrest can be secured in several discrete angular positions whereas movement of the armrest in the first angular position is one-way so that the armrest can only rotate upward and be secured in any one of the several discrete angular positions.
