Abstract
A helmet may be worn on a head of a wearer having a shape and a contour. The helmet may have a plurality of layers coupled together including an energy management layer and an outer shell layer disposed over the energy management layer. The plurality of layers are integrally formed with one another, and the energy management layer is configured to absorb and dissipate energy received by the helmet during an impact by an external force. The outer shell layer is configured to disperse and dissipate impact energy from the external force. Each of the plurality of layers has a density and a geometry, and the density or geometry of at least one layer differs from the density or geometry of at least another layer.
Claims41
A helmet configured to be worn on a head of a wearer, the head having a shape and a contour, said helmet comprising:
- a plurality of layers coupled together including an energy management layer and an outer shell layer disposed over the energy management layer,
- wherein the plurality of layers are integrally formed with one another,
- wherein the energy management layer is configured to absorb and dissipate energy received by the helmet during an impact by an external force,
- wherein the outer shell layer is configured to disperse and dissipate impact energy from the external force, and
- wherein each of the plurality of layers has a density and a geometry, and wherein the density or the geometry of at least one layer differs from the density or the geometry of at least another layer.
A method for fabricating a helmet configured to be worn on a head of a wearer, the head having a shape and a contour, said method comprising:
- integrally forming a plurality of layers disposed on top of one another, the plurality of layers comprising an energy management layer and an outer shell layer, wherein the energy management layer comprises a first density and geometry and has an inner surface with a shape and a contour, the energy management layer configured to absorb and dissipate energy received by the helmet when impacted by an external force, and wherein the outer shell layer is disposed over the energy management layer, the outer shell layer having a second density or a second geometry different than the first density or the first geometry, wherein the outer shell layer is configured to disperse and dissipate impact energy from the external force.
A helmet cage clip comprising:
- an elongate arm;
- a tunnel adjacent one end of the elongate arm, the tunnel sized and shaped to receive and hold a wire of a helmet cage;
- a ramp adjacent the tunnel and configured to urge the wire of the helmet cage into the tunnel,
- wherein actuation of the elongate arm opens a side of the tunnel to receive the wire helmet cage, and wherein the elongate arm is biased to return to a neutral position where the side of the tunnel is substantially closed and configured to hold the wire of the helmet cage.
A helmet comprising:
- an outer shell layer and an energy management layer;
- and
- an occipital cushion releasably or adjustably coupled to the energy management layer, wherein the occipital cushion is configured to cushion or accommodate variances in fit in an occipital region of a wearer's head.
A helmet comprising:
- an outer shell layer and an energy management layer;
- and
- a sweat gutter integrally formed on, or independently applied to an inner surface of the helmet, the sweat gutter configured to direct beads of sweat away from eyes of a wearer.
A method for fabricating a helmet configured to be worn on a head of a wearer, the head having a shape and a contour, the method comprising:
- providing a helmet having a plurality of layers integrally formed with one another, the plurality of layers comprising an energy management layer and an outer shell layer, wherein the energy management layer comprises an inner surface with a shape and a contour;
- and
- heating the helmet and forming the shape and contour of the energy management layer to match the shape and the contour of the wearer's head.
