Patent ID: 8128162

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