A seat comprising:
- a backrest;
- a tray table mounted on the backrest and movable between a stored position, in which the tray table is pressed against the backrest, and a deployed position, in which the tray table is spaced apart from the backrest;
- and
- an additional support mounted on the tray table and movable between a stored position, in which the additional support is pressed against the tray table, and a deployed position, in which the additional support is spaced apart from the tray table, and a locking device capable of selectively taking:
- a locked state, in which the locking device covers an upper edge of the tray table and an upper edge of the additional support, to maintain the tray table and the additional support in the stored position;
- a partially unlocked state, in which the locking device covers the upper edge of the tray table and is disengaged from the upper edge of the additional support, to allow the additional support to move into the deployed position while maintaining the tray table in the stored position;
- and
- a fully unlocked state, in which the locking device is disengaged from the upper edge of the additional support and the upper edge of the tray table, to allow the tray table to move into the deployed position.
