The aircraft tray table may be coupled to the aircraft seat via at least one of one or more hinges or a set of rails, and may be configured to actuate between a stowed position and a deployed position via the at least one of one or more hinges or a set of rails. The tray table magnetic component may be configured to engage the seat magnetic component when the aircraft tray table is in the stowed position. The aircraft tray table retention assembly may include a tray magnetic component configured to engage the tray table magnetic component when the aircraft tray table is in the deployed position. ## Claims ### Claim 1 An aircraft tray table retention assembly, comprising: a seat magnetic component installed within a rear bezel of an aircraft seat; and a tray table magnetic component installed within an aircraft tray table, the aircraft tray table comprising a casing and a frame installed within the casing, a top surface of the aircraft tray table being a surface of the casing, the frame including a cut-out receiving at least a portion of the tray table magnetic component, the aircraft tray table coupled to the aircraft seat via at least one of one or more hinges or a set of rails, the aircraft tray table configured to actuate between a stowed position and a deployed position via the at least one of the one or more hinges or the set of rails, the tray table magnetic component configured to engage the seat magnetic component when the aircraft tray table is in the stowed position, the top surface of the aircraft tray table being in contact with at least one of the seat magnetic component or the rear bezel when the aircraft tray table is in the stowed position, the tray table magnetic component being configured to disengage from the seat magnetic component when a force is applied to at least one of a side surface, an edge, or a corner of the aircraft tray table. ### Claim 2 (depends on 1) The aircraft tray table retention assembly of claim 1, the casing comprising a bottom shell and a top shell attached to the bottom shell, the top shell including the top surface. ### Claim 3 (depends on 1) The aircraft tray table retention assembly of claim 1, the seat magnetic component including a mounting plate fabricated from a magnetic metal, the mounting plate coupled to the bezel via a bezel bracket, the tray table magnetic component including a magnet. ### Claim 4 (depends on 1) The aircraft tray table retention assembly of claim 1, the seat magnetic component including a magnet, the tray table magnetic component including an internal plate fabricated from a magnetic metal. ### Claim 5 (depends on 1) The aircraft tray table retention assembly of claim 1, the seat magnetic component including a magnet of a first polarization, the tray table magnetic component including a magnet of a second polarization, the magnet of the second polarization being configured to attract the magnet of the first polarization. ### Claim 6 (depends on 1) The aircraft tray table retention assembly of claim 1, the seat magnetic component including an electromagnet, the tray table magnetic component including an internal plate fabricated from a magnetic metal, the electromagnet being configured to be controlled via a switch installed on the aircraft tray table, proximate to the aircraft tray table, or within an aircraft cabin 7including the aircraft seat. ### Claim 7 (depends on 1) The aircraft tray table retention assembly of claim 1, the seat magnetic component including a magnetic sensor, the magnetic sensor being configured to transmit information to a controller within an aircraft cabin including the aircraft seat, the information transmitted including a determination whether the aircraft tray table is in the stowed position or the deployed position. ### Claim 8 An aircraft tray table retention assembly, comprising: a tray magnetic component installed within an aircraft tray; and a tray table magnetic component installed within an aircraft tray table, the aircraft tray table comprising a casing and a frame installed within the casing, a top surface of the aircraft tray table being a surface of the casing, the frame including a cut-out receiving at least a portion of the tray table magnetic component, the aircraft tray table coupled to an aircraft seat via at least one of one or more hinges or a set of rails, the aircraft tray table configured to actuate between a stowed position and a deployed position via the at least one of the one or more hinges or the set of rails, the tray magnetic component being configured to engage the tray table magnetic component when the aircraft tray table is in the deployed position, a bottom surface of the aircraft tray being in contact with a top surface of the aircraft tray table when the aircraft tray table is in the deployed position, the tray magnetic component being configured to disengage from the tray table magnetic component when a force is applied to at least one of a side surface, an edge, or a corner of the aircraft tray. ### Claim 9 (depends on 8) The aircraft tray table retention assembly of claim 8, the tray table magnetic component including an internal plate fabricated from a magnetic metal, the tray magnetic component including a magnet. ### Claim 10 (depends on 8) The aircraft tray table retention assembly of claim 8, the tray table magnetic component including a magnet, the tray magnetic component including an internal plate fabricated from a magnetic metal. ### Claim 11 (depends on 8) The aircraft tray table retention assembly of claim 8, the tray table magnetic component including a magnet of a first polarization, the tray magnetic component including a magnet of a second polarization, the magnet of the second polarization being configured to attract the magnet of the first polarization. ### Claim 12 (depends on 8) The aircraft tray table retention assembly of claim 8, the tray table magnetic component including an electromagnet, the tray magnetic component including an internal plate fabricated from a magnetic metal, the electromagnet being configured to be controlled via a switch installed on the aircraft tray table, proximate to the aircraft tray table, or within an aircraft cabin including the aircraft seat. ### Claim 13 (depends on 8) The aircraft tray table retention assembly of claim 8, the tray table magnetic component including a magnetic sensor, the magnetic sensor being configured to transmit information to a controller within an aircraft cabin including the aircraft seat, the information transmitted including a determination whether the aircraft tray is positioned on the aircraft tray table. ### Claim 14 (depends on 8) The aircraft tray table retention assembly of claim 8, the tray table being positionable on a galley workbench, the galley workbench including a galley workbench magnetic component, the tray table magnetic component installed within the tray table being configured to engage the galley workbench magnetic component when the tray table is positioned on the galley workbench. ### Claim 15 (depends on 8) The aircraft tray table retention assembly of claim 8, the tray table being positionable on a galley cart, the galley cart including a galley cart magnetic component, the tray table magnetic component installed within the tray table being configured to engage the galley cart magnetic component when the tray table is positioned on the galley cart.
