Device for fixing a seat rail on a floor, and aircraft equipped with such a fixing device
View Patent ↗A device for fixing a seat rail, designed to maintain passenger seats on a floor, wherein it includes a connecting bracket, secured to the floor and to the seat rail, the bracket being adapted to support the stresses perpendicular to the plane of the floor, and the stresses parallel to the plane of the floor. The bracket extends obliquely between the floor and the rail seat, a lower end of the bracket being secured to the floor and an upper end of the bracket being secured to the seat rail.
1. An aircraft floor comprising seat rails extending parallel to one another, wherein an external seat rail is secured to the floor by means of at least one fastening device comprising a connecting bracket, said bracket being designed to bear forces perpendicular to the plane of the floor and forces parallel to the plane of the floor and in that the connecting bracket has a Z shape, a bottom end of the bracket being secured to the floor and a top end of said bracket being secured to the seat rail, the body of the bracket extending obliquely between the top end and the bottom end.
2. The aircraft floor as claimed in claim 1 , wherein the fastening device comprises an intermediate part designed to secure the bracket to the seat rail.
3. The aircraft floor as claimed in claim 2 , wherein the intermediate part comprises a flat portion secured to the rail and a vertical portion secured to the top end of the bracket.
4. The aircraft floor as claimed in claim 1 , wherein the top end of the bracket has a flat upper face on which the rail is intended to rest.
5. The aircraft floor as claimed in claim 1 , wherein the bracket is made of aluminum.
6. The aircraft floor as claimed in claim 1 , wherein it forms the roof of a landing gear box.
7. The aircraft floor as claimed in claim 1 , wherein it is segmented into compartments by vertical compartment-forming walls , a connecting bracket being housed in each compartment.
8. The aircraft floor as claimed in claim 7 , wherein the top end of at least one bracket is secured to an adjacent compartment-forming wall.
9. An aircraft, wherein it comprises at least one floor as claimed in claim 1 .
