The invention relates to a crossmember (1) of the body of a motor vehicle, intended to interconnect the two upper portions (2) of the passenger compartment sides (3) in a zone located above the bay (4) of the windscreen. The crossmember (1) comprises an upper body shell (1a) made from sheet metal and welded to a lower body shell (1b) made from sheet metal, defining therebetween an elongate hollow body. The invention is characterised in that the cross-section of the hollow body changes progressively between each of its two ends (1c, 1d) that are intended to be connected to an upper portion (2) of a passenger compartment side (3) and the midpoint (M) of the hollow body such as to allow the progressive deformation of the crossmember (1) in the event of an impact exerted on the upper body shell (1a) of the crossmember between the aforementioned end (1c, 1d) and the midpoint (M) of the crossmember.
