Abstract
An energy absorbing liner system and method of making it, preferably by thermoforming. A helmet has an energy absorbing inner system positioned inside the shell. The liner has thermoformed interconnected energy absorbing modules that non-destructively rebound after one or more impacts. 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.
