Abstract
A structural reinforcement for a vehicle comprising: a) a carrier having a base wall from which a plurality of projections extend, the plurality of projections including at least one first projection and at least one second projection and the at least one first projection having a height greater than a height of the at least one second projection; b) an activatable material which is heat activatable and affixed to the carrier, configured to secure the carrier in a cavity of the vehicle; wherein in event of an impact, the at least one first projection and second projection are configured to deform toward the base wall and/or in a direction of an impact load in response to the impact load; and the at least one first projection is configured to receive the impact load and deform before the at least one second projection receives the impact load and deforms.
