1. A tray table assembly for use with a rearward surface of a seatback of a passenger seat, comprising:
- a tray table having a generally planar surface;
at least one support arm attached to said tray table having a free end that extends beyond a forward edge of said tray table and an elongated aperture extending through said free end;
at least one bracket, configured for attachment to the aft surface of the passenger seat, having first and second spaced sidewalls defining a slot there between, wherein a portion of said free end of said support arm is sized for disposition within said slot;
an axel pin extending across said slot between said first and second sidewalls and passing through said elongated aperture pivotally connecting said support arm to said bracket, wherein said support arm is operative to move between a generally vertical orientation where said tray table is in stowed position juxtaposed relative to the aft surface of the passenger seat and a generally horizontal orientation where said tray table is in a deployed position; and
wherein in said generally vertical orientation, positioning said axel pin at a rearward end of said elongated aperture prevents rotation of said support arm to said generally horizontal orientation while positioning said axel pin at a forward end of said elongated aperture permits rotation of said support arm to said generally horizontal orientation.

Abstract
A locking device for a deployable tray table disposed on a rearward surface of a passenger seatback is disclosed. The locking device may be incorporated into a hinge or knuckle of the tray table such that the tray table may be retained in a stowed configuration without a latch mechanism disposed along a top edge of the stowed tray table. In some embodiments, a support arm of the tray table may terminate with a plurality of narrow fingers, each having an elongated slot configured to receive an axel pin disposed within the knuckle.
