In a crash box, a first extending portion extends from a front end of a first body upper portion in a vehicle front-rear direction of a first body portion, and a second extending portion extends from a front end of a second body lower portion in a vehicle front-rear direction of a second body portion. When an impact load is transmitted to the front ends of the first body portion and the second body portion in the vehicle front-rear direction, a rotation moment toward the lower side of the vehicle acts on the first extending portion and a rotation moment toward the upper side of the vehicle acts on the second extending portion. This can suppress peeling between first and second left side bonded portions and between first and second right side bonded portions of the first body portion and the second body portion.

A vehicle bumper is provided integrally to include metal beam-extension portions on both right-and-left end sides of a metal bumper-beam portion. In this vehicle bumper, the bumper-beam portion and the beam-extension portion include a vertical wall portion, an upper wall portion and a lower wall portion, and a resin reinforcing rib is joined to inner surfaces of a void formed of each of the wall portions. In addition, in this vehicle bumper, an extension dimension of the upper wall portion and the lower wall portion of the beam-extension portion is larger than an extension dimension of the upper wall portion and the lower wall portion in the bumper-beam portion, the resin reinforcing rib in the beam-extension portion is joined to the vertical wall portion, the upper wall portion, and the lower wall portion of the beam-extension portion; and the stiffness of the bumper-beam portion is higher than the stiffness of the beam-extension portion.

The present disclosure discloses a bumper beam for a motor vehicle including a center portion free of mobility-specificity and side portions that may be altered according to design and specification of the mobility to secure collision performance so that the bumper back beam of which collision performance is secured and which satisfies various mobilities may be flexibly applied. Accordingly, it is possible to configure the back beam satisfying various mobilities based on a standardized model to secure collision performance so that manufacturing cost is reduced by assembling and producing the back beams with minimum molds.

A bumper for a vehicle includes a bumper crossbeam and two crash boxes extending away from a back of the bumper crossbeam. A one-piece blank made of fiber-reinforced sheet material extends from a wall section of the bumper crossbeam connecting the crash boxes, right into the crash boxes.

The present invention relates to a bumper system for a vehicle, and provides a bumper system for a vehicle, the system comprising: a bumper beam which has a fastening hole formed through each end thereof in the forward and backward direction; a crash box which is inserted into the fastening hole of the bumper beam; and a bracket which is fastened to the bumper beam so as to be able to prevent the crash box from being separated. Thereby, the system can meet both low speed crash regulations and RCAR performance.

An automobile bumper is provided in which the bumper beam includes a middle curved part that curves concavely rearwards and a pair of left and right curved parts that curve convexly rearwards, and the left and right curved parts includes a rear side frame connecting part and a load input part projecting rearwards the most among the bumper beam parts. Since the bumper beam includes a compression-resistant reinforcing part provided along the inner face in the fore-and-aft direction of the load input part, and an extension line of the compression-resistant reinforcing part is directed toward the vicinity of the load input point of the load input part, supporting the compressive load by the compression-resistant reinforcing part to thus prevent the bumper beam from being destroyed enables the strength toward bending deformation to be enhanced without reinforcement by increasing the plate thickness of the bumper beam.

A bumper device for an automobile includes a bumper beam consisting of a fiber-reinforced resin and bumper extensions which consist of a fiber-reinforced resin. The bumper device for an automobile is characterized in that the bumper beam has a Θ-shaped cross-section and in that the bumper beam and the bumper extensions are molded integrally. The bumper device for an automobile has desirable strength and rigidity and is capable of exhibiting excellent energy absorption performance when a large load is inputted to the bumper beam.

A bumper reinforcement includes a body portion joined to a vehicle body front end portion through portions of the body portion on a first direction side and a second direction side in the vehicle width direction, and a reinforcing member joined to the body portion along the body portion. The body portion includes a first standard rigidity region, a high rigidity region, and a second standard rigidity region arrayed next to each other in this order in the vehicle width direction. The high rigidity region has rigidity higher than rigidity of the first standard rigidity region and rigidity of the second standard rigidity region and is positioned in a center of the body portion in the vehicle width direction. The reinforcing member is provided so as to at least partially overlap the high rigidity region and the first standard rigidity region through a first boundary position.

An energy absorber for a vehicle, comprising: a continuous beam to extend across a width of vehicle, the beam defining a plurality of inward facing cavities in a center section, with adjacent inward facing cavities separated from one another by an inward facing rib, and at each end portion a plurality of outward facing cavities, with adjacent outward facing cavities separated from one another by an outward facing rib, wherein the center section includes a panel that is continuous on its outward side, and that forms a relative bottom of each of the plurality of inward facing cavities with its inward face.

A bumper module for a vehicle includes a cross beam and two fastening flanges for fastening the cross beam to a longitudinal body beam. A layer included of fiber-reinforced plastic extends continuously from the cross beam until into the fastening flange.
