Beschreibung
Zusammenfassung:	A mechanical, active crash pulse management structure (100) for providing modification of crash pulse, wherein the structure has a dormant (initial) state volume, but then in the event of a crash, timely expands into a much larger deployed volume for providing management of an expectant crash energy. The preferred crash energy management structure is a before expansion honeycomb celled material brick (102), wherein expansion of the honeycomb brick (102) is in a plane (8) transverse to the cellular axis (A) of the cells thereof, and crash crush is intended to be parallel to the cellular axis. In the event of a crash, either an active or passive activation mechanism (114) is provided for causing expansion of honeycomb celled material (104).
