A bumper assembly for a motor vehicle includes an energy absorber providing a variable stiffness for different displacements. The energy absorber includes a skin portion attached to a bumper beam, a rib pivotally attached to an end of the skin portion and a reinforced element attached to an end of the rib. The rib is movable from a first position that provides a first stiffness for a first displacement to a second position providing a second stiffness greater than the first stiffness over a second displacement.
