A structural member 10 includes a hat member 1 and a closing plate 2. The length LY of the tubular portion formed by the hat member 1 and the closing plate 2 is 6 or more times the height H of a pair of side walls 11 and 12. Each of the side walls 11 and 12 includes a high-strength portion 11A or 12A and low-strength portions 11B or 12B. The high-strength portion has a yield strength not less than 500 MPa. The low-strength portions have a yield strength of 60 to 85% of that of the high-strength portion. Each high-strength portion extends a distance not less than (⅔)H and not more than 3H as measured in the direction in which the ridges extend, and is provided such that the high-strength portions of the pair of side walls face each other. A pair of low-strength portions sandwich the associated high-strength portion.

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 method of managing collisions, the method comprising: identifying a first crash structure (22) and determining an initial stiffness of the crash structure; determining a level of aggressivity of the collision based on the predicted energy absorption for each vehicle; identifying a first crash structure whose stiffness can be adjusted, and determining a subsequent stiffness value for the crash structure based on the determined amount of energy to be absorbed by each of the vehicles such that the energy absorbed by the crash structure is changed and the level of aggressivity is reduced; and stiffening the first crash structure to the determined stiffness value.

A bicycle carrier system for a vehicle includes a guide rail provided on a bumper back beam and formed to extend in forward and backward directions, a carrier portion connected to the guide rail to be slidably drawn out or accommodated along the guide rail, an extended support portion installed on the carrier portion to extend or return in both side directions to carry a bicycle, a motor module installed on the carrier portion and including a first driving portion to enable the carrier portion to move along the guide rail and a second driving portion to extend/return the extended support portion, and a communication control module to store a drawing/accommodating command of the carrier portion and an extending/returning command of the extended support portion and to control operation of the first driving portion and the second driving portion in accordance with an input signal.

A collision countermeasure apparatus for a vehicle includes a longitudinally extending frame rail that defines a transverse opening adjacent a front end. An extension is partially received in a bumper that defines an open end. A pin is received in the transverse opening and has an outer end pivotally connected by a joint to an outboard end of the extension. Collisions outboard of the frame rail drive the extension into the pin and the pin into the rail to laterally displace the vehicle. Collisions inboard of the rail slide the extension outwardly from the bumper and pivot the extension and pin toward each other. Collisions inboard of the rail shift the pin laterally outwardly from the transverse opening.

The disclosure herein relates to vehicle bumper packaging material and method of using. More specifically, the present disclosure relates to a vehicle bumper packaging assembly that is adjustable to fit multiple different bumper shapes and sizes, quick to assemble, and easy to store

A cross member (1) for a bumper beam includes an outer beam (2) with a main beam portion (3) comprising an upper beam wall (12), a lower beam wall (14) and a front beam wall (16), defining together a beam inner volume (17) open in a back direction, a reinforcement element (4) defining a reinforced area (24) of the outer beam (2), located inside a part of said beam inner volume (17) and having a cross section, defining a reinforcement inner volume (25) open in the rear direction, a closing plate (6) closing at least a part of the beam inner volume (17). The cross section of the reinforcement element (4) has a shape which is not matching the shape of the outer beam (2) in the reinforced area (24).

A bumper assembly includes a bumper beam, an extension, a crush can, and a bracket. The bumper beam extends longitudinally from a first end to a second end. The extension attaches to the first end of the bumper beam and has a segment parallel to the bumper beam and a leg extending transversely relative to the bumper beam. The crush can is attached to the segment. The bracket extends from the extension and is welded to the crush can.

A front carriage for a motor vehicle includes a bumper covering and a support structure, which supports the bumper covering. At least one support device supports the bumper covering against the support structure in the direction of the vehicle height (z) and enables a deformation movement of the bumper covering relative to the support structure in longitudinal vehicle direction (x) in the event of a crash.
