Abstract
Abstract A resilient support is provided comprising an elastomer matrix symmetrical with respect to a given axis, a plurality of composite material cables embedded in this elastomer matrix and a plurality of fixing devices allowing the cables to be subjected to flexional forces in any one of three directions of a spatial axis reference system. In a preferred embodiment, the resilient support comprises a cross shaped matrix in the arms of which the cables are embedded and which comprises fixing devices formed by composite blade springs situated in the extension of each arm of the cross.
