Abstract: A compressible liner for a helmet or other apparatus subject to shock loading comprises three substantially co-extensive layers mutually engaged by respective cone-like protuberances and cone-like recesses. The intermediate layer is of a different compressibility and provides for de-coupling of the layers in an oblique impact.

Abstract: A body part protector includes an inner layer defining an interior space that is configured to be occupied by a human body part, an outer layer connected to the inner layer and forming at least one chamber therebetween, and a plurality of separate dampers. A damper is at least partially disposed in the chamber. Each damper extends into the interior space along a respective longitudinal axis. Each damper has an outer end disposed at a fixed position relative to the outer layer and an inner end disposed longitudinally opposite the outer end in the interior space. The protector includes a plurality of separate engagement members corresponding to the plurality of dampers. Each engagement member is disposed at the inner end of the corresponding damper and is configured to engage the body part of the user. Each damper includes a plurality of compressible damper elements concentrically arranged about the longitudinal axis.

Abstract: A helmet comprised of a hard outer shell, a compressible liner in contact with an inner surface of the hard outer shell, and a comfort liner in contact with an inner surface of the compressible liner. The damping hole is defined longitudinally along a longitudinal axis through the hard outer shell, the compressible liner, and the comfort liner. The helmet also includes a pendulum damping system disposed in the damping hole and extending longitudinally from the outer shell to the comfort liner. The pendulum damping system has a pendulum mass that is laterally displaceable within the damping hole.

Abstract: A system for protecting a head of a wearer from an impact force includes a helmet defining an interior space for housing the head and at least one damper coupled to the helmet at a first end and extending therefrom along a longitudinal axis to a second end. The damper includes of a plurality compressible energy damper elements concentrically arranged about the longitudinal axis. The plurality of compressible energy damper elements includes an outer damper element and an inner damper element. The outer damper element surrounds the inner damper element and extends to the second end of the damper. The outer damper element has a first uncompressed length and the inner element has a second uncompressed length that is different from the first uncompressed length. Alternatively, the plurality of compressible damper elements are concentrically arranged and are arranged end to end in series.

Abstract: A compressible liner for impact protection, which may be installed in a helmet worn by a person. The compressible liner may also be applied to other impact protection situations, for example to baby capsules and child safety seats, as well as offering customised zones of impact protection. The compressible liner may have a relatively low density foam inner layer fused to a relatively high density foam outer layer. The inner layer may have many cone shaped protuberances which project into matching recesses of the outer layer. The compressible liner provides an initial low resistance to the impact for a desired part of the human body. As the impact progresses the level of resistance provided by the compressible liner increases in a controlled manner so that controlled deceleration of the part of the body is occurring throughout the impact for a desired impact protection zone of the compressible liner.
