Patent ID: 8622374

Claim:
A buffer for absorbing impacts, said buffer comprising an elastic buffer element made of a material having a first e-module, and a force take-up axis, said buffer element being compressible at least in the direction of said force take-up axis, wherein at least one additional element having a second e-module is enclosed within said buffer element, said second e-module being larger than said first e-module, wherein the buffer element is compressible by 80 to 90% in the direction of the force take-up axis, wherein the additional element is made of such a material that the additional element is deformable to an extent allowing said additional element to follow the deformations of the buffer element when a force is applied, wherein the additional element has the shape of a frustum of a circular cone, the base surface of the additional element extending orthogonally to the force take-up axis of the buffer element.
