Tray table for aircraft seat, deployable by a combined movement limiting its overall size

A tray table for aircraft passenger seat, comprising a deployable plate, forming an operating surface for the passenger, a first support, to which the plate is hinged, and an interface for fastening said table in a seat environment, said table being characterized in that:

• it comprises a second support on which the first support is slidably mounted along a translational direction (T) parallel to the plane of the plate;
• in that the second support is slidably mounted on the interface along the same translational direction (T), so that said supports are telescopically deployable;
• in that the plate is rotatably mounted on the first support, about an axis of rotation (R) perpendicular to the plane of the plate;
• and in that the movements of sliding of the supports and rotation of the plate are coupled, such that said plate performs a gradual and automatic rotation during its deployment and stowing;
• and,
• an actuation mechanism configured to ensure simultaneous sliding of the first and second supports and synchronized and progressive rotation of the plate, said mechanism comprising:
• a first pinion connected to the plate and mounted in a first notched belt connected to the first support, said first notched belt sliding on a cam connected to the second support, said second support comprising a second belt translationally driving the first support via a first slide stage, said second belt being itself translationally driven by a second pinion of the second support cooperating with a rack of the interface, said second pinion driving the second support via a second slide stage.
