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.

A bumper device for a motor vehicle has two bumper support members arranged parallel to the vehicle longitudinal center plane. The bumper device has a bumper crossmember arrangement arranged transversely with respect to the vehicle longitudinal center plane. The bumper crossmember arrangement has two fastening portions at which the bumper crossmember arrangement can be fastened to the associated bumper support member directly or by a respective connecting structure. A central portion between the fastening portions and two lateral end portions protrudes beyond the fastening portions. The central portion of the bumper crossmember arrangement is designed as a frame member surrounding an opening, with an upper crossmember, a lower crossmember, a left support post and a right support post.

A vehicle front-end stiffener includes a hinge bracket pivotally coupled to a support bracket. The hinge bracket supports a stiffener beam. A spring engages the support bracket and the hinge bracket biasing the stiffener beam in a deployed position. A moving element in a locking mechanism can retractably interlock the hinge bracket when a vehicle exceeds a threshold speed to maintain the stiffener beam in the deployed position.

A front under-run protection assembly for a medium duty truck. The front under-run protection assembly includes a front bar assembly and a support assembly. The support assembly includes a beam and attachment plates. The front bar assembly has a bar positioned under the bumper of the truck and shaped to match the bumper shape. The front bar assembly includes a plurality of strengthening gussets attached to a back side of the bar. The bar assembly is attached to the support assembly which is in turn attached to the frame of the truck.

A front structure of a vehicle body may include a sub-frame mounted on a front side member through a mounting plate, a lower crush box connected to each front end portion of the sub-frame along the vehicle body length direction thereof, a radiator support lower member connected to the lower crush box along the width direction of the vehicle, and a lower stiffener connected to the front end portion of the lower crush box along the width direction of the vehicle.

A motor vehicle comprising an aerodynamic underbody flap (1) rotating about a transverse axis (10) and a lower transverse structure (4) arranged at the rear of the lower part of a front bumper (6). The rear part of the lower transverse structure (4) comprises guide means (41, 42) which, in the event of a frontal impact, guide the backward movement of the lower transverse structure (4) such that the rear face of the lower transverse structure (4) comes into contact with the axis (10) of the aerodynamic underbody flap (1).

A vehicle includes a hood at a front end, a frunk under the hood, and a cabin. The vehicle includes a cross-beam positioned between the frunk and the cabin, and configured to inhibit protrusion of the frunk into the cabin in a frontal impact. The vehicle also includes a frame and the cross-beam is coupled to the frame. The cross-beam is a unitary member that is coupled to the frame or the cross-beam includes two members separated by a gap and each member is coupled to the frame. The frame includes shock towers for coupling the cross-beam to the frame. The frame can also include a bracket for coupling the cross beam to the frame.
