Abstract
Apparatus for a swiveling a tray mounted in the back of an aircraft seat. The apparatus has a tube oriented transverse to the seat back around which the tray swivels. A tray is pivotably attached to the tube. A pair of bushes protrude outward from each end os the tube. Each bush ends in a generally mushroom shaped protrusion which is set off by an adjacent undercut defining a stressing and guiding zone. An elastic spring contained within a housing is mounted on the aircraft. The mounted spring has upward directed Y-shaped openings sized to receive and engage the protrusion at the backlash elimination zone and engage the protrusions and the tube. This spring grips and hold the protrusions which secures the tube. This arrangement permits the tube and its attached tray to be quickly and easily attached or removed from the seat. A transmission element in the form of an extending arm is also pivotably attached to the tube. The transmission element is coupled to the tray to urge the tray to rotate with respect to the seat back.
