A removable chin curtain assembly selectively attachable to a helmet is disclosed. The helmet has a helmet shell, a chin strap, and a pair of fasteners connecting the chin strap portion to the helmet shell. The fasteners are made at least in part of ferromagnetic material. The removable chin curtain assembly has a chin curtain and at least one permanent magnet connected to the chin curtain. The at least one permanent magnet is adapted for selectively magnetically connecting the chin curtain to at least one of the fasteners. Alternative embodiments of a removable chin curtain assembly are also disclosed.

A helmet with a gear-constraint type transformable chin guard structure may include a shell body, a chin guard and two branches on the chin guard, wherein a supporting base, the branch, an inner gear, an outer gear and a drive member form an associated mechanism, the inner gear and the outer gear are rotatable about fixed axes and constitute a meshing constraint pair, the inner gear and the branch are in sliding fit with each other and constitute a sliding constraint pair, and the drive member transfer the motion of the outer gear to the branch and causes the chin guard to make an extension/retraction displacement relative to the shell body, such that the chin guard makes an turnover motion while also recombining a reciprocating motion, thereby realizing a transformation between a full-helmet position and a semi-helmet position.

A protective sports helmet that includes a chin strap system that allows for rapid, one-handed adjustment of a chin strap assembly by the player while he/she is wearing the helmet is provided. The chin strap assembly includes a protective chin cup and a pair of straps extending from opposed sides of the chin cup and having a plurality of securing elements. The assembly also includes a pair of adjustable connectors affixed to the helmet and that include a central opening that receives an extent of the strap and a lever that engages a portion of the securing elements. The adjustable connector allows movement of the strap in a first direction, and prevents movement of the strap in a second direction when the lever is engaged with at least one of the securing elements. The adjustable connector allows movement of the strap in both the first and second directions when the lever is not engaged with the securing elements.

A helmet includes a shell having an interior surface, a padding disposed along the interior surface of the shell, and a chinbar. The padding defines a first engagement surface positioned at a first lateral side of the padding and a second engagement surface positioned at an opposing second lateral side of the padding. The chinbar includes a cage, a first flange, and a second flange. The cage includes a first end defining a third engagement surface and a second end defining a fourth engagement surface. The third engagement surface interfaces with the first engagement surface and the fourth engagement surface interfaces with the second engagement surface. The first flange extends from the first end of the cage. The second flange extends from the second end of the cage. The first flange and the second flange of the chinbar are embedded within the padding.

A chin cup that has a hard outer cup and a soft inner cup that may be removable from the outer cup. The inner cup has a peripheral edge extending beyond the edges of the outer cup. Three strap guides, allow a strap to slide through. A one size fits all design includes a central indentation that extends upward toward a top central portion of the cups as well as a central narrowing longitudinally of the cups. Aligned vent holes in the inner and outer cups let the user's chin breathe. The cups have an arcuate longitudinal arch shape. Various embodiments include a boss and hole design that has buttons or mushroom caps that prevent the separation of the cups when not in use and an overmold one piece chin cup embodiment with the soft inner cup imbedded in the hard outer cup.

Systems and methods of a safety helmet for protecting the human head against repetitive impacts, moderate impacts and severe impacts so as to significantly reduce the likelihood of both translational and rotational brain injury and concussions may be provided. The helmet may include an outer shell, an outer liner disposed within and coupled to the outer shell, and an inner liner disposed within and coupled in spaced opposition to the outer liner. A damper array may allow for omnidirectional movement of the inner liner relative to the outer liner and the outer shell.

Protective headgear that is wearable on a head of a user and may be configured to provide impact protection and contaminant protection. The protective headgear may comprise a helmet configured to protect the user's head against impacts and a contaminant blocker configured to protect against contaminants (e.g., infectants), such as pathogens (e.g., viruses, bacteria, or other microorganisms) or other biohazards, chemical hazards, or other hazardous substances, transmittable to or from the user (e.g. as part of spatter, an aerosol, or other droplets). The helmet and the contaminant blocker may be configured to connect or otherwise interact with one another to be usable together. This may facilitate their use to enhance protection of the user and/or an environment of the user, while maintaining performance of the user, including by providing breathability, being spatter proof, ensuring proper vision, being antifogging, being customizable, and/or having other desirable attributes.

A helmet for a goalie is described herein. The helmet includes a head protective outer shell, a chin cup support bracket, and a shock membrane. The head protective outer shell defines an interior space. The head protective outer shell includes an exterior portion and in interior portion. The exterior portion includes an exterior lower section and an exterior upper section. The exterior upper section is curved. The interior portion is opposite the exterior portion. The interior portion includes an interior lower section and an interior upper section. The chin cup support bracket is secured to the interior lower section. The chin cup support bracket includes dual arm members configured to interface with a removable chin cup. The shock membrane is coupled with the interior upper section. The shock membrane includes a honeycomb design adapted to match a curvature of the exterior upper section and the interior upper section.

The present invention relates to a helmet including mouth vents. The helmet of the present invention includes: a chin guard 100 having a first fastening portion 110 and a second fastening portion 120; a vent body 200 having a first fastening protrusion 210 protruding toward the chin guard 100 so as to be inserted into and fixed to the first fastening portion 110 and a second fastening protrusion 220 protruding toward the chin guard 100 so as to be inserted into and penetrate the second fastening portion 120; and fixing means 300 detachably coupled with the second fastening protrusion 220 penetrating the second fastening portion 120 to fix the second fastening protrusion 220 to the second fastening portion 120.
