An interface module for a vehicle crash management system wherein the interface module includes a support structure and a covering layer, and the interface module is adapted for attaching a crash box to a bumper beam. A first section of the support structure is adapted for being placed in direct contact with the bumper beam. A second section of the support structure comprises a recess adapted for receiving one end of the crash box, and the second section is further adapted for being covered by the covering layer. The covering layer is adapted for being arranged on the second surface, such that the support structure is completely enclosed between the bumper beam and the covering layer. Also disclosed are a crash management system and a method for assembling such a system.

A vehicle body front structure includes a front sub-frame configured such that a gear box is fitted to a front part of the front sub-frame, an arm portion extending from a front part of the front sub-frame forward and outward in a vehicle width direction, an impact absorbing portion supported by the arm portion, and a horn portion arranged on a front side of the impact absorbing portion.

A hybrid bumper assembly for a vehicle includes a steel reinforcement beam and aluminum crush cans attached to end portions of the steel reinforcement beam. The reinforcement beam has a multi-tubular shape that is formed by a high-strength steel sheet that is roll formed to provide at least two tubular portions. A crush can has an interfacing portion that is coupled to an end portion of the reinforcement beam. The end portions of the reinforcement beam and the interfacing portion of the crush cans may be configured to attach together using a select joining technology in a manner that minimizes or eliminates bimetallic or galvanic corrosion between the reinforcement beam and the crush cans.

The present invention provides a vehicle body structure comprising an exterior component configured to form an outer surface of a vehicle body and provided with an opening portion; and an attachment component attached on a vehicle body inner side of the exterior component with respect to the opening portion, wherein the exterior component includes an extended portion extended from a periphery of the opening portion toward the vehicle body inner side, and the extended portion includes an abutted portion configured to restrict a displacement of the attachment component to the vehicle body inner side by abutment against an abutment portion provided on the attachment component.

A bumper apparatus for vehicle is disposed between a vehicle body frame extending in a front-to-rear direction of a vehicle and a bumper beam extending in a vehicle width direction. The bumper apparatus includes an axial crush member formed in a hollow cylindrical shape and extending in the front-to-rear direction. The axial crush member has a closed cross-section formed by bonding flat band-like flanges provided on a pair of panels to one another. Each of the pair of flanges is formed in a wavelike pattern along the front-to-rear direction while the pair of flanges is bonded to one another. Each of the pair of flanges has a convex surface and a concave surface as bonded surfaces which are arranged alternately in the front-to-rear direction, and a inclined surface as a non-bonded surface which connects the convex surface to the convex surface and is inclined with respect to the front-to-rear direction.

A reinforcement member has a load-receiving portion and an inclined portion. At least a part of the load-receiving portion is placed in front of a Fr side member. An end, at an inner side in the width direction, of the inclined portion matches in the width direction of the vehicle with a ridgeline at an inner side, in the width direction of the vehicle, of the Fr side member, or is provided at an outer side, in the width direction of the vehicle, in relation to the ridgeline.

A bumper member at a vehicle frontmost end is joined to side members. The bumper member has a curved shape, a center portion protrudes further to the vehicle front than a tip end portion of the side member, a projecting portion is positioned on the outer side of the tip end portion, and is curved toward the vehicle rear, a protruding part extending toward the side member is provided on an inner side of the projecting portion, a tip end portion on the inner side of the protruding part has a planar portion opposite a side face portion on the outer side of the side member, a protrusion protruding to the inner side from the planar portion and extending in the longitudinal direction is provided in the planar portion, and a slit-shaped opening into which a tip end of the protrusion is inserted is provided in the side face portion.

A crossmember for a bumper includes an extruded profile base frame with at least two connecting areas, for attaching the crossmember to a vehicle structure, and which are set at a distance from each other along a longitudinal direction. An extruded reinforcing element is fixedly secured to a rear side of the extruded profile base frame between the at least two connecting areas. The crossmember is weight-optimized and which can be produced in a cost-effective manner.

Front part of the body of a vehicle, comprising side reinforcements in case of a frontal impact with another vehicle. Each of the ends of the front beam (1) comprises a rigid reinforcing end piece (4) secured to, and extending from, the front beam (1) and being curved towards the rear of the vehicle, the reinforcing end piece (4) being covered with a damping cover (6).

Energy absorption at the time of load input is improved with high mass efficiency.

A hollow member includes: a hollow metal member having a bending induction portion in a portion thereof in a longitudinal direction; and a resin material which is disposed in close contact with the metal member on both sides of the bending induction portion in the longitudinal direction, and is disposed in at least a part of a range of less than of a cross-sectional height of the metal member from an end portion of the bending induction portion toward an outside in the longitudinal, in which an amount of the resin material per length in the longitudinal direction is larger on the outside of the bending induction portion than on an inside of the bending induction portion.
