Abstract:
An energy absorber comprising:a base; and a plurality of recesses extending from the base, at least some of the plurality of recesses becoming at least partially compressed during energy absorption and having a rim; a first wall extending between the base and the rim; a first floor; and a second wall extending between the rim and the first floor so that as the first and second walls collapse during energy absorption, some deformation occurs elastically, thereby providing some spring-back following initial deformation, wherein at least some of the plurality of recesses are oriented such that their first and second walls are inclined respectively at angles alpha and beta to a major incident component of the impacting force, where alpha and beta lie between 1 and 45 degrees, and wherein some of the recesses cooperate to afford mutual support in decelerating an object that imparts the impacting force.
