Apparatus for attachment of a unit to attachment devices in a vehicle

An apparatus for attaching an adapter for a flight data recorder to at least a first aircraft seat rail, the first aircraft seat rail being of the type having a first longitudinal axis, said apparatus, comprising:

• a first attachment adapter having a first attachment adapter first part and a first attachment adapter second part;
• the first attachment adapter first part being connectable to the first aircraft seat rail for securing the first attachment first part to the first aircraft seat rail;
• the first attachment adapter second part being connectable to the adapter for a flight data recorder;
• the first attachment adapter also having a first articulated joint by way of which the first attachment adapter first part and the first attachment adapter second part are connected to one another;
• the articulated joint comprising a hole through one of the first attachment adapter first or second parts;
• the hole having a hole thickness in a direction generally parallel to the first pivot axis;
• the first articulated joint being configured to allow the first part and the second part to (i) pivot relative to one another about no more than a first pivot axis oriented transversely to the first longitudinal axis of the first aircraft seat rail and, (ii) be longitudinally moved at least a distance equal to the hole thickness with respect to one another in a direction oriented parallel to the first pivot axis.
