Replacement Bumper Reinforcement
Replacement bumper reinforcement is basically placed behind the crushable energy absorbers. It is made of steel, aluminum, plastic or composite material. Bumper reinforcement that is made of steel may range from mild to high strength and ultra high strength. This is dependent upon the type of vehicle it is used for. There are some bumpers that are designed without covers and have the reinforcement placed positioned before the mechanical energy absorber while others have the reinforcement bar between the cover and the brackets. Also, there are those with bumper reinforcement and brackets while the others have composite bumpers molded with the reinforcement. A rear portion of a bumper shell mounting a lamp is secured in automotive bumper reinforcement. This bumper accessory includes a vertical front wall having a cut-out portion through which a mounting portion of the lamp is passed; a vertical rear wall having a cut-out portion through which the lamp is capable of moving in the event of a collision; and flanges provided at the top and below cut-out portions and spaced apart from each other by a distance that is a little greater than the height of the lamp mounting portion. Generally, bumper reinforcements have a reversely positioned U-shaped cross section that is adaptive to be combined with a bumper face having a generally U-shaped cross section to constitute a bumper. Within an opening of the bumper face with an opening side of the bumper reinforcement directed toward the bumper face, the bumper reinforcement is removably assembled. Likewise, the bumper reinforcement has a plurality of vertical reinforcing ribs that extend vertically to link upper face portion and lower face portion of the reinforcement with each other, as well as for the segments partitioned by the vertical reinforcing ribs, diagonal reinforcing ribs that extend diagonally in the segments and stretched diagonally across vertical reinforcing ribs on both sides of each segment that links them together.
