An armrest assembly for a vehicle seat 5 comprises an armrest portion 11a, 11b, 11c, a shingle head restraint portion 12 moveably attached to one end of the armrest portion 11a, 11b, 11c, to permit the shingle head restraint 12 to be moved towards and away from the one end of the armrest portion 11a, 11b, 11c, and a height adjuster to selectively secure the head restraint 12 in one of a number of predetermined displaced positions relative to the armrest portion 11a, the armrest portion being moveable from a folded up position 11a to a folded down position 11c. The head restraint portion 12 is pivotably mounted for rotation about a substantially horizontal axis 14 and includes a head restraint rotation latching mechanism comprising a latching member biased into engagement with part of the head restraint 12 to hold the head restraint 12 in a preferred rotational position, and a means to automatically disengage the latching member only when the head restraint 12 is brought into close proximity to the armrest portion 11a to permit rotation of the head restraint portion 12 about the horizontal axis.
