Modular arrangement

A vehicle having a passenger cabin and comprising:

• a part of a vehicle body including an outward skin panel outlining an external shape of the vehicle and,
• a structural lining panel inwardly lining the outward skin panel and containing at least one of a polymer material and a natural material, the structural lining panel having a non-planar surface,
• fixation means to directly fasten the structural lining panel to the vehicle body part,
• a module set including at least one module extending in a non-planar surface, the at least one module comprising:
• an airtight envelope and, enclosed under vacuum within the airtight envelope:
• a layer comprising a thermally insulating material,
• wherein said module set is directly fastened to said structural lining panel, and,
• wherein said module set is further indirectly fastened to said vehicle body part, via said fixation means.

A vehicle having a passenger cabin and comprising:

• a part of a vehicle body including an outward skin panel outlining an external shape of the vehicle, the vehicle body part having an inward non-planar surface,
• a structural lining panel which is inwardly lining the outward skin panel, the structural lining panel containing at least one of a polymer material and a natural material, and having a outward non-planar surface,
• fixation means to fasten the structural lining panel to the vehicle body part, a module extending in a non-planar surface, the module comprising:
• an airtight envelope and, enclosed under vacuum within the airtight envelope:
• a layer comprising a thermally insulating material, and,
• wherein said module is arranged between the structural lining panel and the outward skin panel, and
• wherein said module is directly fastened to the vehicle body part, only.

The vehicle according to claim 14,

• wherein said module further includes one of a foam layer, a felt layer and a soundproofing layer chemically bonded with the airtight envelope, so that said one of the foam layer, the felt layer and the soundproofing layer is interposed between the airtight envelope and said vehicle body part, and,
• wherein said direct fastening of the module is a chemical bonding between:
• said one of the foam layer, the felt layer and the soundproofing layer, and
• at least one of the frame and outward skin panel.
