MULTI-STAGE ENERGY ABSORBER

摘要

An energy absorbing liner system that offers a multi-stage reaction to impact and is positioned inside a member that receives an impact. The energy absorbing liner system has one or more interconnected energy absorbing modules that rebound after one or more impacts. At least some of the modules in the layer have a basal portion with multiple levels of reaction to impact. For example, a first stage has one or more membranes. A second stage has energy absorbing units with bendable walls. The membranes extend between the walls of adjacent energy absorbing units. The membranes alone or in combination with the side walls of the units at least partially cushion the blow in multiple stages of reaction by progressively absorbing energy imparted by an object that impacts the outer shell.

1. An energy absorbing liner system that is interposed between an incident surface that receives an impacting force and a mass to be protected from at least some of the impacting force, the energy absorbing liner system having
one or more energy absorbing modules that offer up to a multi-stage resistance to impacting forces, one or more of the energy absorbing modules having a first stage energy absorber with one or more membranes that offer a first level of reaction to impacting forces; a second stage energy absorber with a basal layer and one or more energy absorbing units that extend from the basal layer toward the incident surface, the units having a wall that extends from the basal layer, the units providing a second level of reaction to what remains of the impacting forces after at least partial absorption by the membranes, the one or more energy absorbing units at least partially absorbing energy generated by an impacting object by the wall bending inwardly or outwardly or inwardly and outwardly without rupture.
