Abstract:
A modular energy absorbing assembly comprising:a base; andat least one energy absorbing module associated with the base for accommodating deformation of the assembly,at least some of the at least one energy absorbing modules havinga plurality of separated recesses defined within the base, each of the plurality of recesses havinga floor, andat least one curvilinear wall extending from the floor to the base,wherein at least some of the plurality of recesses are oriented such that their floors are substantially orthogonal to a major incident component of the impacting force and their walls are inclined at an angle alpha to the major incident component of the impacting force, where alpha lies between 0 and 45 degrees, the wall at least partially collapsing and at least some of the recesses becoming at least partially compressed during energy absorption,the assembly serving to decelerate an object that impacts thereupon with an incident force in order to maximize energy absorption over a given distance.
