Bumper assembly

摘要

A bumper assembly includes a bumper beam for absorbing an impact of a vehicle and a crash box attached to the bumper beam and extending along an axis A. A mounting plate is attached to the crash box and defines at least one lateral slot extending laterally along the mounting plate in spaced and perpendicular relationship to the axis A. A fastener extends through the lateral slot for mating with a mounting surface of the vehicle frame to establish a secured position of the bumper assembly. The fastener includes a shoulder disposed in abutting relationship with the mounting surface in the secured position to dispose the mounting plate and the mounting surface in spaced relationship to one another for allowing the fastener to slide laterally along the lateral slot during a vehicle impact to reduce the transfer of lateral impact forces from the bumper assembly to the vehicle frame.

1. A bumper assembly for mating with a mounting surface of a vehicle frame comprising:
a bumper beam for absorbing an impact of a vehicle; a crash box attached to said bumper beam and extending along an axis A; a mounting plate attached to said crash box and defining at least one lateral slot extending laterally along said mounting plate in spaced and perpendicular relationship to said axis A; a fastener extending through said at least one lateral slot for mating with a mounting surface of the vehicle frame to establish a secured position of the bumper assembly; said fastener including a shoulder disposed in abutting relationship with the mounting surface in said secured position to dispose said mounting plate and said mounting surface in spaced relationship to one another for allowing said fastener to slide laterally along said lateral slot during an impact of the vehicle to reduce the transfer of lateral impact forces from said bumper assembly to the vehicle frame; and one of said mounting plate of said bumper assembly and said mounting surface of the vehicle frame defining at least one protrusion biased against the other of said mounting plate and said mounting surface in said secured position of the bumper assembly for reducing vibration between the bumper assembly and the vehicle frame during normal operation of the vehicle and for tuning the lateral impact forces transferred from the bumper assembly to the vehicle frame during the impact of the vehicle.
