Including Energy-absorbing Means Patents (Class 2/411)
  • Patent number: 10357077
    Abstract: A bicycle helmet for protecting the head of a wearer includes an outer shell and an energy dissipating inner layer coupled to the outer shell. The inner layer defines an inner surface, and front attachment locations are inwardly offset from the inner surface substantially at a frontal portion of the helmet. Rear attachment locations are inwardly offset from the inner surface substantially at a rear portion of the helmet. An internal ventilation system is supported by the front attachment locations and the rear attachment locations. The internal ventilation system is configured for direct engagement with the head of the wearer for supporting the helmet upon the head of the wearer. The internal ventilation system provides a gap between the head of the wearer and the inner surface. The gap allows ventilating air to flow over a substantial extent of the wearer's head and within the helmet.

    Abstract: A helmet includes one or more pads on an inside surface of a shell, with the pads including a cushioning material that includes porous particles within a carrier liquid. The surfaces of the pores of the particles are lyophobic, resisting wetting by the carrier liquid. When the carrier liquid is placed under sufficient pressure, for example by an impact against the pad, the carrier liquid is forced into the pores. This causes the system to store and absorb energy within the carrier liquid. The pad may be made of flexible material with a pair of opposed major surface face pieces, with cells full of the liquid and particles extending between the face pieces. The liquid and particles may make up a majority of the volume of the pad, for example being at least 50% of the volume of the pad.

  • Patent number: 9414636
    Abstract: A bicycle helmet for protecting the head of a wearer includes an outer shell and an energy dissipating inner layer coupled to the outer shell. The inner layer defines an inner surface, and front attachment locations are inwardly offset from the inner surface substantially at a frontal portion of the helmet. Rear attachment locations are inwardly offset from the inner surface substantially at a rear portion of the helmet. An internal ventilation system is supported by the front attachment locations and the rear attachment locations. The internal ventilation system is configured for direct engagement with the head of the wearer for supporting the helmet upon the head of the wearer. The internal ventilation system provides a gap between the head of the wearer and the inner surface. The gap allows ventilating air to flow over a substantial extent of the wearer's head and within the helmet.

  • Patent number: 9408423
    Abstract: A sport equipment for absorbing and dispersing, at least in part, an impact force, thereby reducing the impact force. The sport equipment can be a helmet having an outer shell, an inner shell, and a tensile sheet located between the outer and inner shells. The outer shell includes an interior side featuring a plurality of outer shell detents extending out therefrom. The inner shell includes an exterior side featuring a plurality of inner shell detents extending toward the outer shell. The tensile sheet is configured to dissipate and redirect, randomly directed impact force applied to the outer shell, to a tensile loading directed along a respective longitudinal axis of the tensile sheet. The outer and inner shells are in a spaced apart relationship with and movable to each other. The outer shell detents extend toward the inner shell.

  • Patent number: 9332800
    Abstract: A helmet structure without any hard outer shell has axially compressible cell units contained in a hemispheric frame by a thin fabric covering stretched over cup shaped cell retainers that have sidewalls of compressible foam. The frame is supported on the wearer's head on plastic foam posts that space the inner ends of compressible bladders from the wearer's head, and ambient air in the bladders compresses at impact, being vented then through openings for gradually absorbing such impact forces. Each bladder is vented into a space between the cup “bottom” and the outer end of a bladder. At least two cell sizes are provided, and some of these are on depending lobes in the frame, for protecting the wearer's ears and neck.

  • Patent number: 9210962
    Abstract: A reinforcement structure of safety helmet and a manufacturing method thereof. The reinforcement structure includes a helmet body formed of a cushion foam material; and a structure body integrated with the helmet body. The structure body is a texture at least composed of multiple strip members arranged in an array. The structure body is formed with a substantially cellular structure. The helmet body is defined with a top section and a peripheral section and the structure body is defined with a first section and a second section connected to the first section corresponding to the top section and peripheral section of the helmet body. The cushion foam material is injected into a molding module to enclose the first and second sections to form an integrated complex reinforcement structure, which is easier to manufacture and has higher structural strength, lighter weight and higher security.

  • Patent number: 9179727
    Abstract: A helmet includes an inner and outer shell that are connected posterior of the head via a two degree freedom of movement rotating hinge. The connector allows for angular rotation about the inferior/superior and left/right axes. One potential mechanism for the connector is four springs, located left, right, inferior and superior of the connector, connected to both the inner and outer layers. The goal of the springs is two-fold to provide resistance in the event that the outer layer rotates with respect to the inner layer about either axis in response to an impact or applied force, and to rapidly return the outer layer to its equilibrium position post-impact or after the removal of the applied force.
