Abstract

L'invention a trait à une structure arrière (102) d'un véhicule automobile, ladite structure (102) comprenant un plancher (104) ; deux profilés structurels arrière (106) s'étendant longitudinalement vers l'arrière depuis le plancher (104) et comprenant, chacun, une partie avant (110), une partie arrière (112) surélevée rapport à ladite partie avant (110), et une partie intermédiaire (114) formant un ressaut et reliant les parties avant et arrière (110, 112). La structure (102) comprend, en outre, deux renforts (118) sur les deux profilés structurels arrière (106), respectivement ; chaque renfort (118) s'étendant longitudinalement sous le profilé structurel (106) correspondant et étant fixé aux parties avant (110), et arrière (112) dudit profilé structurel (106) et configuré pour limiter un pivotement vers le haut de la partie intermédiaire (114) dudit profilé structurel (106) en cas de choc à l'arrière sur ladite structure (102).The invention relates to a rear structure (102) of a motor vehicle, said structure (102) comprising a floor (104); two rear structural profiles (106) extending longitudinally rearwardly from the floor (104) and each comprising a front portion (110), a rear portion (112) raised relative to said front portion (110), and an intermediate part (114) forming a projection and connecting the front and rear parts (110, 112). The structure (102) further comprises two reinforcements (118) on the two rear structural sections (106), respectively; each reinforcement (118) extending longitudinally below the corresponding structural channel (106) and being secured to the front (110), and rear (112) portions of said structural channel (106) and configured to limit upward pivoting of the portion intermediate (114) of said structural section (106) in the event of rear impact on said structure (102).
