Abstract: A motor vehicle has a passenger compartment and two side members provided with respective rear portions, arranged longitudinally at the passenger compartment, and respective struts, which project forward of the passenger compartment; the motor vehicle has a crossbar with front attachment portions and rear attachment portions fixed to the side members by means of connecting devices, so as to keep the crossbar suspended in relation to the struts; the connecting devices have at least one weakened zone, designed so as to cause at least part of the crossbar to detach from the side members when a given load threshold is exceeded; the connecting devices have a first pierced wall, which is part of the front or rear attachment portions, a second pierced wall, which is part of the side members, and a bolt that tightens the first and second wall together; the weakened zone is defined by at least one slot cut in the first wall, beginning from a hole edge of the first wall itself.

Abstract: An end structure of a motor vehicle body has two longitudinal struts which extend along respective axes have respective ends, on which respective attachment plates are fitted; the attachment plates have respective walls, which are ring-shaped about longitudinal axes and defined frontally by respective faces having substantially vertical and flat resting zones; two supporting plates rest respectively on these resting zones and are fixed to the walls and to two buffering elements, which are substantially coaxial to the struts; the two attachment plates further have respective tabs, which are radiused to said walls at an inner annular perimeter thereof and end with respective edges, which are longitudinally aligned with the supporting plates.

Abstract: A motor vehicle body has a structure defining a passenger compartment, two primary longitudinal struts, and two secondary longitudinal struts; the primary struts are arranged in lower positions and more inwards with respect to the secondary struts and are provided with front end portions adapted to support a front end of the motor vehicle; such front end portions are joined to the secondary struts by means of respective connection devices having respective intermediate portions extending along respective directions which are substantially symmetric with respect to a vertical centerline plane and diverge, extending backwards.
