  • the present invention relates to a trim assembly intended to be fixed to a body structure forming part of an internal ceiling of a vehicle.
  • the invention also relates to a method of assembling such a trim assembly, and a vehicle comprising at least one such trim assembly.
  • the vehicle is, for example, a car of a high-speed train or an intercity train, the vehicle comprising at least one side wall and a ceiling framing a passenger compartment.
  • a ventilation device In order to air-condition such a vehicle, it is known to position a ventilation device on the side wall of the vehicle. Openings are provided in said side wall delivering air-conditioned air.
  • the side wall and the openings provided therein form a trim assembly.
  • trim assembly is usually small, making it difficult to integrate a ventilation device into the side walls, particularly due to the fact that the side walls are thin in order to reduce the width of the vehicle.
  • the openings are located at passenger height. This makes the openings visible to passengers, which is aesthetically disturbing and reduces passenger comfort.
  • the openings are also easily accessible, so small objects are likely to be introduced or fall into them.
  • trim assemblies comprising an upper panel are known from documents CN 212 980 195 U , FR 2 542 828 A1 , or even KR 100 865 882 B1 .

  • the main part 66 comprises two protrusions 72 similar to the protrusions 50 present on the lower profile 42.
  • Each protrusion 72 comprises a partition 74 and a return 76 and the protrusions 72 correspond on the upper panel 34 to a claw.
  • the stop 80 projects from the main part 66 in the transverse direction T.
  • the stop 80 has a height in the transverse direction T greater than the distance in projection in the transverse direction T of the distance between the distal end 62 of the convex portion 58 and the reinforcement 64.

  • the fixing portion 28 is connected to the first end 46, for example to the protrusion 56, fixing the lower panel 36 to the body structure 12. Simultaneously, for example, one of the rails 26 of the body structure 12 is snapped into the claw of the lower panel 36.
  • the assembly of the cladding assembly 14 is easy and quick.
  • the cladding assembly 14 thus offers easy maintenance. This also saves space for placing the ventilation device 16.
  • the ventilation openings 40 are thus concealed from the passenger compartment 18, avoiding visual discomfort.
  • the openings 40 are difficult to access for a passenger, not shown, placed in the passenger compartment 18, avoiding injuries or loss of small objects.
  • the covering assembly 14 is blocked in rotation in the longitudinal direction L. This also makes it possible to solidify the connection of the covering assembly 14 to the body structure 12.
  • the trim assembly 14 can be directly fixed to the body structure 12 and adapted so that the fixing part 28 is connected to a window or to a side wall 20.
