Vehicle pillar reinforcement construction for side impact

摘要

A side structure for a vehicle is provided and includes a sill and a header spaced apart from the sill. A pillar outer body extends between the sill and the header and defines an inner channel open toward an interior of the vehicle. An inner cover is attached to the pillar outer body and extends between the sill and the header. The inner cover has a lower cover portion disposed proximate to the sill and formed of a first material having a first ductility and an upper cover portion disposed proximate to the header and formed of a second material having a second ductility less than the first ductility.
