Definitions
- the primary supports are generally used to fix the trunk of electrical equipment on the roof of this car.
- the pavilion is generally made of aluminum.
- the primary supports are exposed to fire. Since the primary supports are made of a metallic material, therefore a heat conductor, the part of the roof adjacent to the primary support can reach or exceed the melting temperature of aluminum.

- the car 10 also includes at least one secondary support 42 interposed between the boot 24 and the roof 16.
- the secondary support 42 is suitable, in the event of the roof 16 collapsing in the area of the primary supports 26, to support the weight of the boot 24.
- the secondary supports 42 are arranged in the central part 36 of the bottom wall 30.
- the car 10 comprises two secondary supports 42 arranged symmetrically with respect to a plane of symmetry of the roof 16, parallel to the direction vertical Z and in the longitudinal direction X.

- the upper rim 48 has a shape substantially identical to that of the lower rim 46. In the preferred configuration, the upper rim 48 has the same dimensions as the lower rim 46.
- the vertical wall 50 of the secondary support 42 has, in the vertical direction Z, a height less than the distance between the trunk 24 and the roof 16 when the pavilion 16 is in the rest position. In other words, when the pavilion 16 occupies its rest position, a vertical distance 52 occurs between the lower wall 30 and the upper rim 48.
- the secondary support 42 also comprises at least one reinforcement rib 54 projecting perpendicularly from the vertical wall 50, and extends substantially over the entire transverse width of the upper and lower edges 46, 48.
- the reinforcement ribs 54 are able to reinforce the structure of the secondary support 42 in the vertical direction Z.
- the secondary support 42 comprises two reinforcing ribs 54.
- the car 10 further comprises a thermally insulating strip 56 disposed on the upper surface of the upper rim 48 facing the boot 24.
- the insulating strip 56 is capable of reducing the transfer of heat between the boot 24 and the supports secondary 42. When the trunk 24 is in the rest position, the insulating strip 56 is away from the bottom wall 30 of the trunk 24.
- the flag 16 When there is no subsidence of the flag 16, the flag 16 is in the rest position.
- the trunk 24 is supported by the primary supports 26, and is spaced from the secondary supports 42.
- the primary supports 26 When there is a significant increase in temperature near the pavilion 16, due for example to the presence of a fire, the primary supports 26 are exposed to heat. Being made of metallic material, the primary supports 26 transfer heat to the roof 16 and thus heat it.
- Pavilion 16 is made of aluminum which has a melting temperature of 660 Ā° C. When the temperature near the primary supports 26 of the trunk 24 approaches this melting temperature, the pavilion 16 softens, and collapses under the effect of the weight of the trunk 24 near the primary supports 26.
- the trunk 24 therefore begins to descend, and the lower wall 30 approaches the secondary supports 42. In doing so, the vertical spacing 52 decreases until the trunk 24 comes into contact with the upper flanges 48.
- the secondary supports 42 being less exposed to heat and in particular to radiation, the part of the pavilion 16 at their proximity remains solid and able to support the weight of the trunk 24.
- the upper edges 48 exert a supporting force on the trunk 24, and the descent of the trunk 24 is stopped.
- the invention makes it possible to obtain a more solid attachment of the boot 24 during a fire and makes the car more reliable.

Le fonctionnement du dispositif selon l'invention est dƩcrit ci-dessous.The operation of the device according to the invention is described below.
Lorsqu'il n'y a pas d'affaissement du pavillon 16, le pavillon 16 est en position de repos. Le coffre 24 est soutenu par les supports primaires 26, et est Ć l'Ć©cart des supports secondaires 42.When there is no subsidence of the
Lorsqu'il y a une augmentation importante de la tempĆ©rature Ć proximitĆ© du pavillon 16, due par exemple Ć la prĆ©sence d'un feu, les supports primaires 26 sont exposĆ©s Ć la chaleur. Etant rĆ©alisĆ©s en matĆ©riau mĆ©tallique, les supports primaires 26 transfĆØrent de la chaleur vers le pavillon 16 et ainsi le rĆ©chauffent.When there is a significant increase in temperature near the
Le pavillon 16 est rĆ©alisĆ© en aluminium qui prĆ©sente une tempĆ©rature de fusion Ć 660Ā°C. Lorsque la tempĆ©rature Ć proximitĆ© des supports primaires 26 du coffre 24 s'approche de cette tempĆ©rature de fusion, le pavillon 16 se ramollit, et s'affaisse sous l'effet du poids du coffre 24 Ć proximitĆ© des supports primaires 26.
Le coffre 24 commence donc Ć descendre, et la paroi infĆ©rieure 30 s'approche des supports secondaires 42. Ce faisant, l'Ć©cartement vertical 52 diminue jusqu'Ć ce que le coffre 24 entre en contact avec les rebords supĆ©rieurs 48.The
