Abstract
A seat that can be converted between an upright position and a bed position, includes a mechanism for deploying an armrest, The mechanism includes a first guide connection comprising a first roller mechanically connected to the moving part associated with the seat-cushion portion, the first roller collaborating with a first slot formed in the armrest, and a second guide connection comprising a second roller mechanically connected to a fixed part, the second roller collaborating with a second slot formed in the armrest, such that a movement of the seat-cushion portion of the seat as the seat transitions from the upright position to the bed position causes the armrest to move from the up position to the down position.
