ABSTRACT:
A vehicle seat assembly with an attitude adjustable armrest is provided to enable the armrest to be adjusted to maintain a horizontal position when the seat back is reclined rearwardly. The attitude adjustment mechanism includes a cam lock which prevents downward rotation of the armrest while permitting upward rotation of the armrest. The cam lock mechanism includes a cam fixed to the seat back having an arcuate cam edge surface and a pawl having an edge surface engaging the cam surface. The pawl plate is attached to the armrest and spring biased into engagement with the cam plate to prevent downward rotation of the armrest. A release mechanism is provided to disengage the pawl from the cam to enable the armrest to be adjusted downwardly.
