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.
Claims25
A helmet comprised of:
- a hard outer shell;
- a compressible liner in contact with an inner surface of the hard outer shell;
- a comfort liner in contact with an inner surface of the compressible liner, where at least one damping hole is defined longitudinally along a longitudinal axis through the hard outer shell, the compressible liner, and the comfort liner;
- and
- at least one energy damper disposed in a corresponding damping hole and extending longitudinally from the outer shell to the comfort liner, the damper having a pendulum mass that is laterally displaceable within the damping hole.
A helmet comprised of:
- a hard outer shell;
- a compressible liner in contact with an inner surface of the hard outer shell;
- a comfort liner in contact with an inner surface of the compressible liner, where a damping hole is defined longitudinally along a longitudinal axis through the hard outer shell, the compressible liner, and the comfort liner;
- and
- a pendulum damping system disposed in the damping hole and extending longitudinally from the outer shell to the comfort liner, the pendulum damping system comprised of:
- an outer compressible disc attached to the outer shell;
- a rod coupled to the outer disc and extending longitudinally inwardly to an inner compressible disc to which the rod is coupled;
- the inner compressible disc attached to the compressible liner;
- and
- a head stabilizer flexibly coupled to the inner compressible disc and spaced longitudinally and inwardly from the inner compressible disc, wherein the head stabilizer is configured to engage a head of a wearer of the helmet.
