Claim 7:
8. An adaptive energy absorption module for a vehicle bumper assembly, the adaptive energy absorption module comprising:
a primary deformable impact absorber member defining a first/primary impact chamber having a shape that is structurally adaptive or otherwise conforms to an impact force received by a bumper body of the vehicle bumper assembly;
a secondary deformable impact absorber member arranged in the primary impact chamber and itself defining a secondary impact chamber containing a shear thickening fluid that exhibits a decreasing viscosity responsive to the impact force; and
a plurality of fluidically connected tertiary deformable impact absorber members arranged in the primary impact chamber and itself defining a plurality of tertiary impact chambers containing a volume of fluid, and having a shape that is structurally adaptive to the impact force.
