Abstract
A helmet with an inner liner and an outer liner that slidably move in relation to each other. At least one flexible connector is positioned at the ovoid surface between the inner and outer liner that directly connects at least three of a plurality of liner ribs of the first liner segment to the second liner segment across a gap at a center portion of a second liner segment and at left and right sides of the second liner segment. The at least one flexible connector is in-molded with the first and second liner segments so that they move relative to each other when the inner liner slidably moves in relation to the outer liner by flexing the at least one flexible connector. Elastomeric anchors coupled to the outer liner and to the at least one flexible connector may be included, and a fit system may be used.
