Abstract: A seat impact energy absorbing system having an energy absorbing module that limits forces transmitted through the seat to its occupant. Such forces may emanate from, for example, a land mine detonation. The module has frustoconical structures joined by hollow interconnecting ribs that create support pillars there between. At least some of the support pillars have tops.

Abstract: A seat impact energy absorbing system having an energy absorbing module that manages forces emanating from, for example, a land mine detonation. The module has frustoconical structures joined by hollow interconnecting ribs that create support pillars there between. At least some of the support pillars have tops that underlie an occupant-supporting surface. To receive forces associated with detonation, an impact-receiving surface underlies the energy absorbing module.

Abstract: A vehicle includes a beam and fascia over the beam, and an energy absorber mounted between the beam and fascia. The energy absorber is thermoplastic and has energy-absorbing wall geometries that are forwardly facing and configured to absorb energy from a low speed impact against a pedestrian. The wall geometries having multiple wall sections defining multiple draft angles and lengths adapted to buckle at transitions of the multiple draft angles during the low speed impact, with the numbers and types of draft angles and transitions of these draft angles being varied to provide a selected amount of resistance force needed to absorb an optimal amount of energy over time during the impact. The energy absorber is tuned for optimal minimized injury to an impacted object.
