Abstract
An energy-absorbing hood assembly for a vehicle includes an inner layer operatively secured to an upper layer having a first interface surface. The inner layer has opposing first and second surfaces defining a sinusoidal profile that is oriented to extend from the forward end of the vehicle towards the rearward end of the vehicle. The sinusoidal profile includes varying amplitudes and wavelengths along different regions of the hood assembly. The amplitudes and wavelengths are individually configured to provide regionally distinct predetermined levels of absorption and attenuation of kinetic energy imparted to the hood assembly by an object upon impact therebetween. Preferably, the hood assembly also includes a lower layer having a second interface surface; wherein the inner layer has a plurality of bonding surfaces attached to the first and second interface surfaces to thereby define a plurality of laterally oriented channels.
