  • Patent number: 11975837
    Abstract: A vehicle region with a roof section of a primary structure and with two luggage compartments. One of the luggage compartments comprises a detachable luggage compartment flap and a luggage compartment top, which forms the upper boundary of a part of a luggage space. A detachable fastening device can rotatably fasten the luggage compartment flap on the luggage compartment. A front edge of the luggage compartment top is at a distance from an end point in an intermediate space above a luggage compartment, to which end point a side of a ceiling panel is movable, the distance being greater than or equal to a width of the ceiling panel. Methods for installing and removing a ceiling panel above two luggage compartments are provided, wherein the ceiling panel is guided at least partially through a luggage space of a luggage compartment when the luggage compartment flap has been removed.
