VEHICLE BUMPER BEAM CONSTRUCTED OF METAL AND PLASTIC

摘要

A bumper system for a vehicle comprising a stamped metal component and a second polymeric component fixedly attached to form a beam with particular localized energy absorber characteristics. The metal component is formed from a sheet and has a thickness in a width direction along a majority of the length when in a vehicle-mounted position. The second polymeric component engages a face of the first component and is rigidly attached to the first component in at least several locations along the length to form a structural beam with the first component. The second polymeric component has sufficient structure to form an integral part of the structural beam and interconnected walls extending in the width direction to form energy-absorbing cells at centered and corner locations configured to crush and absorb energy upon a vehicle impact.
