An apparatus includes a bumper beam including an outer face, a plate elongated along the outer face, a plurality of ribs elongated from the plate transverse to a direction of elongation of the plate, and a plurality of cylinders each fixed to one of the ribs and spaced from the plate.

A shock absorbing member includes an outer member being hollow and made of a metal, and an inner member held in the outer member. The inner member includes a wood member and a bracket that is made of a solid resin or a metal and that is integral with the wood member. The inner member includes a holding structure configured to position and hold the bracket to the outer member.

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.

A vehicle front structure includes a pair of side rails extending in a vehicle forward-rearward direction on right and left sides in a front portion of the vehicle and a hollow bumper reinforcement extending in a vehicle right-left direction and coupled to front ends of the pair of side rails. The bumper reinforcement includes side extension parts extending outward beyond the side rails, respectively. The vehicle front structure further includes load transmission members each extending from a front face of each of the side extension part of the bumper reinforcement through the side extension part and further extending rearward and toward the inward of the vehicle. In a small overlap crash, the load transmission member transmits a collision load directly to the side rail.

A structure of the vehicle includes a rear side member, a crush box and a bumper reinforcement. The rear side member is arranged outside in a width direction of the vehicle and is extended with a length direction of the rear side member coinciding with a longitudinal direction of the vehicle. The crush box plastically deforms through compression of the vehicle. The bumper reinforcement is provided with a hat-shaped open cross-section where a recess portion recessed outward with respect to the vehicle is provided in an inner surface of the bumper reinforcement in the longitudinal direction of the vehicle. A width of an open-end portion of the recess portion in a vertical direction of the vehicle is set larger than a width of the rear side member and a size of the crush box in the vertical direction of the vehicle.

A bumper assembly includes a bumper elongated along a first axis. The bumper assembly includes a first energy absorbing device extending from the bumper, the first energy absorbing device having a second axis perpendicular to the first axis, the first energy absorbing device being elastically deformable along the second axis. The bumper assembly includes a second energy absorbing device within the first energy absorbing device and being shorter than the first energy absorbing device.

A vehicle bumper may include a bumper absorber having a tube receiving groove that extends in a vehicle width direction, and an elastically deformable airtight pressure tube received in the tube receiving groove formed on the bumper absorber and in communication with a pressure sensor. The bumper absorber includes a beam-shaped absorber body portion extending in the vehicle width direction, and an elongated projecting portion extending in the vehicle width direction at a front end periphery of an upper surface of the absorber body portion. The tube receiving groove is configured to extend in the vehicle width direction on the upper surface of the absorber body portion while penetrating into a rear end portion of the elongated projecting portion, and is configured to open backward.

A pedestrian protection device for a motor vehicle, in particular for a front part of the motor vehicle, includes a bumper crossbeam and a deformation element arranged in front of the bumper crossbeam. The deformation element has a bending section, the end of which is in contact with a surface or which comes into contact with the surface in the event of a collision, in particular a front collision of the motor vehicle. The end of the bending section is designed such that it can move along the surface as a result of the collision, wherein the surface has an engaging device with which the end of the bending section can be, in particular, engaged.

Disclosed is a polyolefin resin, a method for preparing the same, and a vehicle rear bumper beam using the same. The polyolefin resin is characterized by being composed of a thermoplastic resin composite including a polymer base including a polypropylene homopolymer, which has a molecular weight distribution of 2 to 10, and a colorant; and a fiber reinforcing material that is impregnated into the polymer base and has a length of 5 to 20 mm, wherein 10 to 50 wt % of the fiber reinforcing material is included with respect to the polyolefin resin. The method is characterized in that a thermoplastic resin composite is formed by impregnating a molten mixture including a polypropylene homopolymer, which has a molecular weight distribution of 2 to 10, and a colorant with a fiber reinforcing material having a length of 5 to 20 mm.

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).
