摘要

A seat rail for supporting seats in an aircraft comprises a support portion for connection with the cabin floor and a seat receiving portion having a groove for receiving the end portions of connector elements coupled with the support frame of a seat. The support portion comprises a profile arrangement of a fibre-reinforced polymer, preferably carbon fibre-reinforced polymer, having a central main portion and flanges which extend outwardly from and perpendicular with respect so said main portion to form a support surface for the seat rail. The main portion comprises a slot open at least at its end remote from the flanges. At least one metal element comprising the groove for receiving the end portions of the connector elements has a leg which is inserted into the slot of the main portion and is secured therein. The seat rail may be manufactured in a continuous process.
