Abstract: A seat rail for attaching seats in aircraft is provided. The seat rail includes a profile element for attaching the seats, and a support element for attaching the seat rail in an aircraft. At least the support element is manufactured from aluminum or an aluminum alloy. The surface of the aluminum or the aluminum alloy includes, an oxide layer, and the oxide layer has been manufactured by means of hard anodic oxidation.

Abstract: The invention relates to a device for supporting a door which is pivotably received in a fuselage airframe of an aircraft, with a counter bearing arranged in the region of a doorframe and a thrust bearing located opposite in the region of the door. According to the invention, the counter bearing has a planar counter bearing surface and the thrust bearing has a mounting in which a planar thrust bearing surface which can tilt about at least one spatial axis is received, the counter bearing surface lying against the thrust bearing surface at least in some regions when the door is closed. Because of the thrust bearing surface which can be tilted in at least one spatial direction, the counter bearing always lies against the thrust bearing over the entire surface areas thereof, irrespective of any manufacturing tolerance deviations between the doorframe and the door or the bearing on the fuselage airframe, in such a way that optimal force transfer is ensured.
