The invention relates to a rail arrangement for coupling a displaceable element to a support structure, wherein the rail arrangement comprises a guiding rail and a fitting. In this arrangement the fitting is connectable to the displaceable element, and the guiding rail is connectable to the support structure. The fitting is arranged in the guiding rail in such a way that the fitting can be displaced in longitudinal direction of the guiding rail; wherein the guiding rail is formed as an open-top hollow profile with a rail base. In this arrangement the rail base comprises at least one elevation that extends upwards (i.e. towards the open-top). The fitting comprises a bottom surface which in longitudinal direction is interrupted by a continuous groove, wherein the form of the groove of the fitting is designed in such a way that the fitting is guided by the elevation along the guiding rail.

Rail arrangement for guiding a fitting inside guiding rails particularly in aircrafts

A rail for fastening installations in an aircraft, the rail including a rail base section, a running-surface section that extends in a longitudinal direction with a running surface, and a connection section that connects the running-surface section to the rail base section at the face pointing away from the running surface. The running-surface section laterally on both sides, in each case spaced apart at a predetermined pitch, includes a multitude of projections projecting away from the connection section, each with a top that has substantially the same alignment as the running surface and a bottom that has an alignment that substantially is opposed to the alignment of the running surface. The bottom of the projections forms holding surfaces for holding a fitting. The rail is attached to a floor of the aircraft.
