Abstract: A device for locking an equipment item onto a locking track attached to the floor of a cabin comprises a support component, the underside of which comprises a insertion section adapted to the contour of a longitudinal slot of the locking track, where said insertion section can be inserted into the locking track, and on the support component a sliding part that can be inserted into the locking track is guided so it can be longitudinally shifted, the outer contour of which corresponds to that of the insertion section, wherein the sliding part can be shifted in the locking track relative to the support component in order to lock the support component on the locking track.

Abstract: Incoming air system for passengers in a passenger compartment, in which the supply duct does not have to be reconstructed if the seat configuration is altered. This is provided by means of an air distribution element, which is continuous in the longitudinal direction of the aircraft and which comprises openings at defined positions which are adapted to possible seat layouts. Openings which are not required are sealed, for example by means of a selection element which encloses the air distribution element and is slitted on one side.
