Abstract
An adjustable armrest for a vehicle seat in which a ratchet mechanism is provided to resist downward movement of the armrest and allow upward movement to adjust the armrest position relative to the seat back. The ratchet mechanism is released upon raising the armrest passed the upper end of its adjustment range enabling the armrest to be lowered to the lower end of its adjustment range wherein the ratchet mechanism again engages to hold the armrest in place. Attachment of the armrest to the seat back is provided by sliding the armrest over a mounting stud extending laterally from the seat back. A wire spring clip attached to the armrest seats in a groove in the stud to hold the armrest axially on the mounting stud. When assembled, the spring clip will be positioned at the interface between the armrest and the seat back enabling a flat tool such as a screw driver to be inserted between the armrest and the seat back to manipulate the clip to remove the armrest.
