A bumper crossmember for a vehicle having a first crossmember provided by an outer shell facing away from the vehicle and an inner shell facing toward the vehicle, which two shells are connected to one another along their circumference. This crossmember has at least one passage oriented in the direction of its longitudinal extension and extending over its middle with respect to its longitudinal extension (y direction), and by which the crossmember is divided into an upper hollow chamber section and a lower hollow chamber section. Crash boxes arranged at distance from one another are connected to the lower hollow chamber section on its side facing the vehicle. The bumper crossmember has a second lower crossmember spaced apart in the z direction from the lower hollow chamber section and connected by at least two connector parts to the lower hollow chamber section of the first crossmember. Crash boxes arranged at a distance to one another are connected on the side of the second crossmember facing the vehicle.

A bumper for a motor vehicle has at least one longitudinal beam and a transverse beam that is secured to the longitudinal beam. The transverse beam is designed as a hollow profile body and is produced by connecting, in a material fit, a plurality of straps and webs.

A closed cross-sectional structure member includes a hollow member, the hollow member having a collision side wall part located on a collision side, an opposed collision side wall part opposing the collision side wall part, a pair of first side wall part and second side wall part connecting with end portions of the collision side wall part and end portions of the opposed collision side wall part, a first inner wall part extending from the first side wall part to an inside of the hollow member, a second inner wall part extending from the second side wall part to the inside of the hollow member, a third inner wall part connecting with the first inner wall part and the collision side wall part, and a fourth inner wall part connecting with the second inner wall part and the collision side wall part.

Provided is a vehicle body front part structure having an increased degree of freedom in design while maintaining transmission performance of collision load. A vehicle body front part structure includes a front side frame, a bumper beam bracket provided at a front end in the front side frame, a subframe provided below the front side frame, and a subframe support provided in a standing manner below a position behind the front end in the front side frame, the subframe support being connected to the subframe, the subframe support includes a pair of left and right side walls and on opposite sides in a vehicle width direction in the subframe support, and each of the pair of left and right side walls and extends forward and is connected to a lower end in the bumper beam bracket.

A bumper arrangement for a motor vehicle, having a crossmember which is able to be coupled to a motor vehicle by means of crash boxes. The crossmember is designed as a hollow profile which is open on one side. An opening of the hollow profile faces forwards. The crossmember is designed in its end portions to run with an orientation obliquely downwards with respect to the vertical direction.

A front bumper includes a bumper fascia, an upper panel, and a shock absorbing member and a rigidity member in the interior of the upper panel. The shock absorbing member is formed in a hat shape in cross section by a front wall, an upper wall (a front-side upper wall and a rear-side upper wall), a rear wall, and a lower wall. The rigidity member includes an upper end portion fixed to the upper wall, a lower end portion fixed to the lower wall, and an intermediate portion connecting the upper end portion and the lower end portion in the vehicle up-down direction. The intermediate portion is spaced apart from the rear wall in the vehicle front-rear direction.

A variable back beam and a method of allowing an inflator to vary the variable back beam in case of collision. The variable back beam includes a main beam connected to a front end module carrier, an inner beam inserted into each of both sides of the main beam, and an operation member operable to move the inner beam in a vehicle-width direction at the time of left front or right front collision of the vehicle. Since the back beam is extended in length at the time of collision, the impact area or shock absorption area of the back beam can be increased, the impact on the back beam, a crush box, and a collision object can be reduced, and particularly, it is possible to reduce the crush length of the left or right end of the back beam.

A vehicle comprises: a vehicle body having a front and a rear; a vehicle chassis supporting the vehicle body, the vehicle chassis including a chassis portion; a component attached to the front of the vehicle body; and a member comprising (i) an elongate portion having teeth, and (ii) an attachment portion attaching the member to one of the chassis portion or the component, wherein the member is configured for ratcheting of the teeth against an edge of the other of the chassis portion or the component due to relative movement between the component and the chassis portion.

An automotive vehicle includes a body having fore and aft portions. The vehicle includes a bumper beam coupled to the vehicle body proximate the fore portion and a heat exchanger disposed aft of the bumper beam. A fascia assembly is coupled to the vehicle body and extends about the bumper beam. The fascia assembly includes a fascia inlet configured to direct an airflow from the exterior of the fascia assembly to the interior of the fascia assembly. An energy absorption member is disposed between the fascia and the bumper beam. An air passage extends through at least one of the bumper beam and the energy absorption member. The air passage extends from an air passage inlet to an air passage outlet. The air passage inlet is positioned downstream of the fascia inlet with respect to the airflow, and the air passage outlet being positioned upstream of the heat exchanger.

A pedestrian contact detection apparatus, for a vehicle, includes a bumper beam, an absorber, an upper rib, a lower rib, a contact detection sensor, and a cover. The upper rib and the lower rib each protrude from a front face of the absorber toward a vehicle front side and each extend discontinuously in a vehicle width direction. The lower rib is disposed on a vehicle lower side of the upper rib. A pressure tube extends in the vehicle width direction and is disposed between the upper rib and the lower rib. The cover covers a front face of the absorber from the vehicle front side, includes a support having insertion holes through which the upper and lower ribs are disposed, and is disposed on the vehicle front side of and adjacent to the bumper beam. The support supports the pressure tube from a vehicle rear side.
