An energy absorber for interposition between a cover and a covered object includes a generally planar matrix of cells. Each of the cells includes a plurality of generally elongate micro-elements interconnected to form a cell micro-structure, with each cell having a respective energy absorption capacity such that an energy absorption capacity of the energy absorber varies across at least one direction. The cells are configured such that impulse of an object with the cover with the energy absorber sandwiched between the cover and the covered object causes a deceleration vs. time response in the object, beginning with a generally linear rise in the deceleration to a peak deceleration within 5 ms after the beginning of the impulse event, followed by a generally nonlinear decrease in the deceleration over a period of not greater than 15 ms to a final target deceleration of not greater than 10% of the peak deceleration.

A louver for a vehicle includes a panel having a central portion and a first outer edge portion. A hinge interconnects the central portion and the first outer edge portion. The louver rotates about a rotation axis in a first direction from an open position to a closed position. The hinge bends to allow the first outer edge portion to move relative to the central portion to reduce an effective moment arm resisting rotational movement of the louver when the louver is bound.
