FOUR WAY ADJUSTABLE ARMREST

摘要

A four way adjustable armrest for use on a vehicle seat includes an arm support member having a extension member and the armrest is connected to a seat back including a pair of toothed track members extending along the seat back. A toothed gear is movable on the extension member of the armrest between an engaging position where the armrest position is locked and a retracted position where the gear teeth are removed from the toothed track members and the armrest is free to rotate and to translate along the track members via a track follower. The gear has a splined inner diameter and is carried on mating splines on an outer surface of the cylindrical extension member. A pivoting actuating member moves or throws the gear on the splined extension member between the engaged and retracted positions.
