The longitudinal load-arresting cross-member 5 consists, for example, of a bent tube 51 fastened at each of its ends 52, 53 to the support element, in particular to the respective lateral parts of the element. of support. Advantageously, attachment points 330, 340 of the support member on the rear floor of the body can be used to mechanically connect the ends 52, 53 of the welded tube 51 to the support member. In addition, near each of the ends 52, 53 of the longitudinal load-arresting crossbar 5, a force-recovery leg, 54, 55, extending perpendicularly to the cross-member, respectively, is provided. the rear portion of the rear body floor relative to the cross member and 10 to connect the cross member 5 and the support member 3 on either side of the receiving area 31 of the battery. The force recovery legs 54, 55 thus making it possible to take up the forces exerted on the cross member 5 in the longitudinal direction. According to the exemplary embodiment, the support element 3 further comprises fastening means 36 adapted to allow the attachment of a battery case (cladding around the battery, not shown). The support element 3 also preferably comprises a longitudinal reinforcing bar 6 removably mounted on the support element 3 and adapted to extend transversely substantially facing the battery receiving zone 31, so as to constitute a support for the battery case at the top of the battery case when the case is mounted around the battery on the support member. According to the exemplary embodiment, the longitudinal reinforcing bar 6 of the battery casing is mounted at each of its ends, for example by means of fixing screws, on support lugs 56, 57 projecting substantially vertically from the Stress recovery legs 51, 55. Finally, according to the exemplary embodiment, the support member 3 comprises gripping handles 37, located on either side of the receiving zone 31 of the battery. Each of these gripping handles 37 is, for example, constituted by a curved wire forming a hoop, fixed at each of its ends to the surface of the support member, on each side of the battery receiving zone. The gripping handles 37 thus secured to the support member are adapted to cooperate with a mounting assistance means for handling and placing the support member on the rear floor of the body. In particular, a tool having the shape of a fork with two horizontal carrying longitudinal members intended to cooperate with the gripping handles 37 arranged on each side of the battery receiving zone of the support element, can be used to handle the support member, especially for lifting and installing or removing the support member. The "all-in-one" integration of the support element 3 of the various functions described above makes it possible to prepare assembly of the assembly 10 at the edge of the assembly line, before being put in place in the vehicle. This facilitates the operation of mounting and implementation of these functions within the vehicle, and keeps good ergonomics in preparation at the edge of the chain, rather than multiple interventions inside the vehicle. 15 20 25
