Described are assemblies that include elements of a tray table, such as for an aircraft or other passenger craft. A tray table body can be movable between a stowed configuration and a deployed configuration. A set of arms may support the table body relative to a seat back in the stowed configuration and in the deployed configuration. In response to movement of the seat back (such as in a crash scenario), the arms may permit release of a constraint of the tray table body that would otherwise inhibit the tray table body from moving with the seat back.
