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 multi-tiered recoiling energy absorbing system has an upper impact surface that is exposed to percussive impact. At least one energy absorbing layer is positioned below or inside the upper impact surface. The energy absorbing layer includes one or more energy absorbing modules. At least some of the modules are provided with one or more energy absorbing units that extend from an upper platform. Several of the energy absorbing units are provided with a flexible wall that extends from the upper platform. A lateral reinforcement member secures the energy absorbing units to prevent them from splaying. The energy absorbing units at least partially absorb energy generated by an impacting object due to the flexible wall bending inwardly or outwardly and recoiling nondestructively after single or multiple impacts to its un-deflected configuration.

Abstract: A liner system and method of thermoforming. A helmet has an energy absorbing inner system positioned inside the shell. The liner has thermoformed interconnected energy absorbing modules. At least some of the modules in the layer have a basal portion with upper and lower sections when viewed in relation to the wearer's head. The upper section has one or more energy absorbing units. At least some of the units are provided with a wall with a domed cap that faces the outer shell. The units at least partially cushion the blow by absorbing energy imparted by an object that impacts the outer shell. The lower comfort section has a tiered arrangement of layers. The layers are relatively compliant and thus provide a comfortable yet firm fit of the helmet upon the wearer.

Abstract: A recoiling energy absorbing system has an outer shell that is exposed to percussive impact. An energy absorbing layer is positioned inside the outer shell. The energy absorbing layer includes one or more thermoformed energy absorbing modules, at least some of the modules being provided with one or more energy absorbing units that extend from an upper basal layer. At least some of the energy absorbing units are provided with a flexible wall that extends from the upper basal layer. The energy absorbing units at least partially absorb energy generated by an impacting object due to the flexible wall bending inwardly or outwardly and recoiling nondestructively after single or multiple impacts to its undeflected configuration.
