The vehicle body includes left and right side frames that extend in a vehicle body forward-rearward direction and support a collision load acting from the front or the rear, and a coupling member that is joined to open ends of the side frames and restricts displacement between the open ends in a direction in which the open ends are away from each other. The side frame has a plurality of low-strength sections disposed with high-strength sections interposed therebetween in the vehicle body forward-rearward direction and having a lower strength than the high-strength sections in the vehicle body forward-rearward direction. The low-strength section closer to the open end has a lower strength in the forward-rearward direction.

Vehicle body

The vehicle body includes: a pair of left and right rear side members extending in a front-rear direction of the vehicle body, and a rear bumper beam which extends in a left-right direction of the vehicle body to be coupled to each rear side member at both ends, and bulges rearward toward a center of the left-right direction. The rear bumper beam has an intermediate body extending in the left-right direction at the center of the left-right direction, and inclined bodies which are displaced forward as expanding to the left and right toward the respectively corresponding rear side member from both ends of the intermediate body. A rearward surface of the intermediate body includes a vertical surface, and an inclined surface which is continuous from at least either an upper end or a lower end of the vertical surface and is displaced forward as separating from the vertical surface.

A vehicle body structure includes a bumper beam extending in a left-right direction, and left and right side members functioning as a frame member supporting both ends of the bumper beam. The bumper beam includes a connecting member that connects the both ends to suppress the extension between the both ends.

Vehicle body structure

A bumper beam of a vehicle body structure () is provided with a laterally extending laterally middle part () and a pair of end parts () each extending from a corresponding lateral end of the middle part in an outboard direction with a certain inward slant with respect to a fore and aft direction, and each end part curves at a laterally middle point thereof so as to have a concave side facing outward with respect to the fore and aft direction.

Each rear side member () of a vehicle body rear structure includes a first deformable portion (), a second deformable portion (), a third deformable portion (), and a fourth deformable portion () in that order from a rear end thereof on an inboard side and an outboard side in an alternating manner and in a mutually spaced apart relationship, and the distances between the adjacent deformable portions are substantially 1:2:1:1 in ratio as measure from the rear end of the rear side member.

A metal piece having at least two areas of lower mechanical strength than the body of the piece, said pieces being respectively arranged on one side and the other of a longitudinal central section (PM) of said piece and alternatively located in two locations separated longitudinally along the piece, the areas of lower mechanical strength than the body of the piece being formed by local control of the stamping temperature during a stamping process of the piece, notably a process comprising steps including heating the piece to a temperature range suitable for obtaining an austenitic stage, then stamping this piece in a stamping tool suitable for defining different temperatures in the different areas of the stamped piece, for example by virtue of the voids formed in the stamping tool or by local reheating of the stamping tool.
