An armrest for a vehicle seat, the vehicle seat comprising a seat cushion and a backrest, the armrest being adapted to be turned around a pivot axis between a first active position above and substantially parallel to the seat cushion and a second folded-away position substantially parallel to the backrest, the armrest comprising:

• an upper part, the upper part having a longitudinal axis and, in the first active position, the upper part being positioned with its longitudinal axis substantially parallel to an substantially vertical plane through a side surface defining an outer edge surface of the vehicle seat, the upper part being adapted to support a user's forearm;
• at least one lower part provided with a fixing device for attaching the upper part to the vehicle seat, the lower part comprising a linking mechanism arranged for setting the upper part in a transverse direction between a first position outside the side surface and an adjustable second position when the armrest is in its active position;
• and
• a locking device arranged to activate a catch that locks the upper part in a set position after it has been moved to the adjustable second position.
