AbstractAn energy absorbing structure suitable for example of use in a motor vehicle body panel to absorb impact loads comprises a wall having a plurality of ridges extending in a longitudinal direction corresponding to the expected direction of an applied load, and at least one reinforcement secured to the wall on adjacent ridges. The dimensions of the ridges and the points at which the reinforcement is secured are so arranged that the wall undergoes progressive collapse under impact in the longitudinal direction.
