Energy absorbing structure.

摘要

It is known that conical shapes, particularly conical shapes of fibre reinforced plastics, have desirable progressive energy absorption characteristics. According to the invention, the broad end of a conical fibre reinforced plastics structure (18) is positioned so as to receive the load, with the narrow end being secured to a relatively fixed structure (16), and the wall of the structure being constructed so that the broad end of the structure collapses first and the rest of the structure progressively collapses towards the narrow end.
