The disclosure provides an interior trim part for a motor vehicle having a sliding or panoramic roof comprising a headliner and a stiffening frame attached to the headliner and enclosing and stabilizing an opening in the headliner enclosing the sliding or panoramic window, the stiffening frame being made of a fiber-reinforced composite material comprising a fiber mat and a textile lattice material, the textile lattice material being applied over a surface of the fiber mat and impregnated together therewith.

The present disclosure provides a header for a vehicle upper body structure. The header includes an elongated body extending between a first side and a second side. The elongated body includes a polymer and a plurality of fibers. The elongated body includes a front end and a back end. The front end is configured to be coupled to a windshield. The back end is configured to be coupled to a roof. At least a portion of the elongated body has a transparency of greater than or equal to about 4%.

A vehicle ceiling material includes: a base material; a skin layer provided on a vehicle-interior side of the base material and forming a ceiling surface in a vehicle interior; a back surface layer as a film layer provided on a back-surface side of the base material; a first adhesive layer between the base material and the skin layer; and a second adhesive layer between the base material and the back surface layer. The vehicle ceiling material includes a fiber body layer formed of a fiber and provided, between the back surface layer and the second adhesive layer, partially to the back surface layer. A part in the back surface layer and over the fiber body layer is cut out.

Methods and systems for a vehicle headliner is provided. In one example, the headliner is a layered assembly, including a base substrate layer and a skin and is configured with a bracket inserted into the base substrate layer. The bracket has a top plate co-planar with a first surface of the base substrate layer and a continuous wall coupled to the top plate. The bracket is positioned in the base substrate layer such that the base substrate layer does not protrude into the skin.

A vehicle having a passenger cabin to be maintained within a temperature range, the vehicle comprising a vehicle body and an assembly defining the passenger cabin, the assembly including: a structural lining panel having a surface and being non-planar, fixation means for attaching the structural lining panel to the vehicle body, and a modular assembly including a plurality of side-by-side modules, each module extending in a non-planar surface and including: an under vacuum envelope and, a layer of a thermally insulating material, the side-by-side modules being arranged side by side in a direction parallel to the surface of the structural lining panel.
The side-by-side modules are joined to said structural lining panel while being joined to said vehicle body only by said fixation means.

A roof structure includes a roof panel constituting a roof of a vehicle, a roof headlining constituting a ceiling of a vehicle cabin, and a stiffening board disposed between the roof panel and the roof headlining. The stiffening board is attached to a lower face of the roof panel by adhering at plural adhesion portions. Steps are formed at the stiffening board between the respective plural adhesion portions so as to widen a space between the stiffening board and the lower face of the roof panel.

A method for stiffening a curved sheet-metal panel, in which a flat cardboard panel is applied to the concave face of the curved sheet-metal panel, includes a step in which a number of parallel cuts that pass partially through the thickness of the cardboard panel are made in that face of the cardboard panel that is intended to be applied to the concave face of the sheet-metal panel. A number of adhesive strips that each cover said parallel cuts are applied to said face of the cardboard panel and said face, provided with said adhesive strips, of the cardboard panel is applied to said concave face of the sheet-metal panel.
