Apparatus for attachment of a unit to attachment devices in a vehicle
View Patent ↗An apparatus for attachment of a unit to attachment devices in a vehicle, in particular an aircraft, has attachment elements which are provided for connection to the attachment devices. In this case, at least one attachment adapter is provided, and can be connected on the one hand to the unit to be attached and on the other hand by means of the attachment elements to at least one attachment device.
1. 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.
2. The apparatus as claimed in claim 1 wherein the aircraft also has a second aircraft seat rail, the second aircraft seat rail having a second longitudinal axis, the apparatus further comprising: a second attachment adapter by way of which the adapter for a flight data recorder is connected to the second aircraft seat rail.
3. The apparatus as claimed in claim 2 wherein the second attachment adapter comprises:
a second attachment adapter first part and a second attachment adapter second part; the second attachment adapter first part being connectable to the second aircraft seat rail for securing the second attachment adapter first part to the second aircraft seat rail; the second attachment adapter second part being connectable to the adapter for a flight data recorder; the second attachment adapter also having a second articulated joint by way of which the second attachment adapter first part and the second attachment adapter second part are connected to one another in a manner allowing the second attachment adapter first part and the second attachment adapter second part to (i) pivot relative to one another about a second pivot axis oriented transversely to the second longitudinal axis and, (ii) be moved with respect to one another in a direction oriented parallel to the second pivot axis.
4. The apparatus as claimed in claim 3 wherein the second articulated joint includes a second bolt which is centered about the second pivot axis and passes through the second attachment adapter first part and the second attachment adapter second part and connects the second attachment adapter first part and the second attachment adapter second part to one another.
5. The apparatus as claimed in claim 2 , wherein the second attachment adapter is essentially rigid, while the first attachment adapter compensates for at least one of stressing and twisting by allowing the first part and the second part of the first attachment adapter to pivot relative to one another about the first pivot axis.
