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: A luggage compartment of an electric traction vehicle has a floor, an electric/electronic unit for recharging a battery pack, and a support structure provided with a frame that supports such electric/electronic unit in a fixed position; the support structure has an attachment portion which is arranged in front of the frame, is fixed to the floor and is joined to the frame by means of a deformable portion, adapted to bend about an axis which is horizontal and transverse to a travel direction of the vehicle; the floor is provided with a pushing element having a support surface, on which a lower surface of the frame rests at a point which is higher than the bending axis of the deformable portion.

Abstract: A floor-panel structure for a vehicle includes a front body subassembly, a front floor structure, including a central longitudinal tunnel, two lateral longitudinal beams, connected to the floor structure and the body subassembly, and two intermediate longitudinal beams, which connect the floor structure to the body subassembly and extend in areas between the lateral longitudinal beams and central longitudinal tunnel. The lateral longitudinal beams each include a sheet-metal profile element having an open cross section, a front portion reinforced for withstanding relatively high axial loads, and a remaining portion that is more ductile than said front portion so as to be more liable to collapse. Each lateral longitudinal beam is constituted by a single sheet element of steel, and said reinforced front portion is constituted by a hardened portion obtained by subjecting only the front portion to a thermal treatment using high-frequency induction heating.

Abstract: A motor vehicle has a front engine compartment housing a powertrain unit and at least one side-member on which a safety device is mounted; the safety device is configured so as to move said powertrain unit sideways during an impact, towards the opposite side to that which is subject to the impact; the safety device is provided with a beam having a first end, spaced from a terminal portion of the side-member towards the outside of the engine compartment, and a second end fixed to the side-member at an intermediate portion next to the powertrain unit; the safety device is further provided with a pin, which is fixed with respect to the second end of the beam and projects from said second end through a hole of the intermediate portion towards the powertrain unit.

Abstract: A motor vehicle has an engine compartment accommodating a powertrain and at least one strut, which is substantially parallel to an advancing longitudinal axis of the motor vehicle; the motor vehicle has a safety device configured so as to move the powertrain sideways during an impact, towards the side opposite to the one concerned by the impact; the safety device is provided with a beam having a first end, distanced from an end portion of the strut towards the outside of the engine compartment, and a second end fixed to the strut in a position which is horizontally beside the powertrain; the safety device is also provided with a restraining member fixed to the strut and having a protruding portion arranged behind a wall of the beam.

Abstract: A motor vehicle has two upper struts, which project forward from a passenger compartment and are arranged above two lower struts, which extend along respective substantially rectilinear axes inclined from the bottom upwards, going forward; the lower struts have respective intermediate portions with such a variation in cross section to define a preferential bending zone; the rear ends of the lower struts are fixed to a cross member connected to the upper struts by means of two connection members, which are substantially vertical and have respective breakable zones designed so as to break when a given load threshold is exceeded; the motor vehicle also has a powertrain connected to the cross member and to the upper struts by means of supports which are distinct from the connection members and are breakable in the event of a front crash.
