A B pillar for a motor vehicle is produced as a hot-stamped and press-hardened component composed of a hardenable steel alloy, wherein a lower length section extends over less than 40% of the length (L) of the B pillar in a longitudinal direction and at least regionally has different strength values in relation to an upper length section, which B pillar is, in the lower length section, in at least one cross section, mutually different strengths are formed, and in the lower length section, a soft material structure is formed regionally.

A plate-shaped body component for a motor vehicle has a planar core zone, a planar edge zone and a first intermediate zone, which is set off from the core zone and from the edge zone by at least one step each. The core zone and the edge zone are deflected against the first intermediate zone in opposite directions of a surface normal of the first intermediate zones.

A die apparatus including a first die element, a plurality of second die elements, a plurality of actuators, and a controller is provided. Each of the plurality of actuators is mounted to one of the plurality of second die elements. The controller is programmed to activate the actuators to contact and compress portions of a blank disposed between the die elements at separate pressures to influence microstructure forming for one of a geometry transition region, a deformation region, and a joining region. One of the separate pressures applied to one of the portions of the blank may be approximately 5 N/mm.sup.2 or less to form a soft strength zone. The pressure of approximately 5 N/mm.sup.2 or less may be applied to the one of the portions of the blank for approximately one to two seconds.

A front body structure of a vehicle includes a pair of left and right hinge pillars, a pair of left and right front suspension dampers that are provided in desired positions on an inner side in a vehicle width direction of the hinge pillars and on a vehicle front side of the hinge pillars, a pair of left and right suspension housings that have damper mount parts, and a pair of left and right apron reinforcements to which upper ends of the suspension housings are joined. The apron reinforcements are formed in shapes extending substantially linearly from the rear ends thereof toward the vehicle front side and an inner side in the vehicle width direction through an outer side in the vehicle width direction of the damper mount parts in plan view.

This disclosure relates to a motor vehicle, and in particular a vehicle body structure for a motor vehicle, with an extended roof reinforcement structure. An example vehicle includes an A-pillar, a roof side rail, a dash panel, and a reinforcement structure extending at least partially through the roof side rail and the A-pillar to a front end forward of the dash panel.

A profile includes two end wing portions with substantially a transversal direction (Y), two lateral wall portions having substantially a height direction-(Z), a frontal wall portion having substantially a transversal direction (Y), two curved transition zones (R1, R2) disposed between the lateral wall portions and the frontal wall portion, and two curved transition zones (R3, R4) disposed between the end wing portions and the lateral wall portions. A specific portion of each curved transition zones (R1, R2) between the lateral wall portions and the frontal wall portion has a tensile strength lower than the tensile strength of the rest of the cross-section. This configuration also relates to a longitudinal beam, a cross-member, a pillar, a B-Pillar or a C-Pillar having the profile, and to a vehicle provided thereof.

This bonded structure includes a first member having a metal portion and a film portion disposed on at least a part of a surface of the metal portion; a second member; an adhesive layer for joining the first member and the second member to each other via the film portion. The film portion contains a resin and inorganic particles. The inorganic particles are formed of ferrosilicon or non-oxide ceramics containing V. Some of the inorganic particles protrude toward the adhesive layer. The particle size of at least some of the inorganic particles protruding toward the adhesive layer is less than the film thickness of the film portion.

A vehicle front body structure includes a lower side frame member and an upper frame member each extended in a longitudinal direction of the front body structure. The upper frame member is arranged above, in a height direction of the front body structure, and on an outboard side, in a width direction of the front body structure, of the lower side frame member. A damper housing is arranged to connect the lower side frame member and the upper frame member. The damper housing includes an outboard wall, in the width direction, affixed to the upper frame member. The outboard wall includes a deformation relief feature extended in the longitudinal direction along an opening provided on the damper housing for an associated vehicle suspension component.

Rocker structure (R1-R3) for a vehicle comprising a first steel profile (1) and a second steel profile (2) having the longitudinal direction (L) of the vehicle so that a channel (CH) is defined therebetween, the first and second profiles(1, 2) comprising a vertical central section (13), the rocker structure (R1-R3) comprising a first impact absorption element (3) arranged in the channel (CH), wherein the first impact absorption element (3) is a closed steel profile wherein an upper lobe (31) and a lower lobe (32) joined by a central joining section (33) are defined, the upper lobe (31) being located closer to the upper joining flanges (11, 21), the lower lobe (32) closer to the lower joining flanges (21, 22). The invention also relates to a method for obtaining the rocker structure and to vehicles provided with the inventive rocker structure.

A blank (100) includes a main portion (110) that is made of steel having a tensile strength of 1450 MPa or more and a softened portion (120), the ratio of Vickers hardness of the softened portion (120) to the Vickers hardness of the main portion (110) is 0.7 or more and 0.95 or less, and the softened portion (120) is disposed at a position different from a position of the main portion (110) in an in-plane direction. A structural member (200) includes a first member (210), a second member (220), and a weld (W) at which the first member (210) and the second member (220) are welded to each other.
