Abstract

A rail for the fastening of equipment elements, such as, in particular, seats, in aircraft, includes a holding region for connection to an equipment element of an aircraft, and a support region to fasten the rail to a carrier element of the aircraft. The rail has a metallic shell which is, for example, made of titanium and which is filled with a fiber-reinforced thermoplastic filler material which is reinforced by short fibers. To produce the rail, a metallic molded part is used as a casting mold and is filled, for example by injection, with the filler material and, after the rail has been produced, forms the metallic shell for the filler material.

Claims6

Dependent claims

A method for producing a rail for fastening equipment elements in an aircraft, comprising the steps:

molding a rail part, being for the fastening of equipment elements of the aircraft, from metal with a holding region and a support region for fastening to a carrier element of the aircraft,
filling the holding region of the rail part with a filler material and,
wherein, after the rail part has been produced, the rail part forms a metallic shell for the filler material,
wherein the metallic shell defines a cavity having a first end separated from a second end by an intermediate portion, the first end having a cross-sectional area greater than a cross-sectional area of the of the intermediate portion taken parallel to the cross-sectional area of the first end,
wherein the filler material is located within the first end of the cavity and the intermediate portion of the cavity.
