Abstract
An element for the absorption of energy which contains reinforcing elements which extend at least partially in the direction of compression to which the element is subjected, wherein the reinforcing elements within the element are encircled by plastic foam particles glued or welded to one another, said reinforcing elements at least partially taking up the compressive force whereby they buckle in on overshoot of a compression of at most 20% with respect to their length in the direction of compression.

An element for the absorption of energy which contains reinforcing elements which extend at least partially in the direction of compression to which the element is subjected, wherein the reinforcing elements within the element are encircled by plastic foam particles glued or welded to one another, said reinforcing elements at least partially taking up the compressive force whereby they buckle in on overshoot of a compression of at most 20% with respect to their length in the direction of compression.
A method of forming an energy absorbing element, comprising:
- placing reinforcing elements within a mold cavity in a position such that the elements extend in the direction of stress which is applied to the product body in its use;
- filling the mold cavity with plastic foam particles thereby enveloping the reinforcing elements;
- heating the contents of the mold thereby bonding the foam particles to each other to obtain a shaped plastic body.
