A helmet comprising one or more additively-manufactured components designed to enhance performance and use of the helmet, such as: impact protection, including for managing different types of impacts; fit and comfort; adjustability; and/or other aspects of the helmet. Methods of additively-manufacturing components for such helmets are also provided, including methods involving expandable materials and the expansion of post-additively manufactured expandable components.

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 full-face helmet for use in sport is provided. The helmet comprises a rigid outer shell for fitting about a top, back and sides of a user's head, and a detachable chin guard for partially covering a user's face. The detachable chin guard is magnetically connected to the sides of the rigid outer shell. A secondary fastening means is provided on the chin guard as a pair of hinged clips.

An auxiliary visor system for use with or without helmet. Includes an attachment band formed of an improved stretch loop material with loop connector material on one side and silicone on the second. The second, inward facing side secures the front visor to the helmet. The stretch material provides inwardly-directed force to the exterior surface of a helmet. The silicone material is flexible and also provides frictional grip to secure the attachment band to the exterior of the helmet. A hook material fastener couples to the loop connector material on the exterior of the improved stretch loop material to close the attachment band. An optional detachable visor attaches to the outside of the attachment strap formed of the stretch loop material with hook material.

The present invention discloses a sports helmet. The helmet comprises a rigid shell defining a cavity configured to fit over a user's head, a frame pivotally connected to the shell via a linkage, a wire mesh attached to the frame and adapted to extend across the user's face. The wire mesh comprises an opening transversely extending across the user's eyes. A transparent eye shield is disposed at the opening of the mesh. The eye shield comprises holes to prevent accumulation of fog and allow airflow to provide clear vision to the user. A shock absorber is disposed at an interior side of a bottom portion of the wire mesh. The shock absorber is configured to conform onto the facial contour of the user upon impact with an object and mitigate effect of impact force. Further, concussion sensors are embedded in the helmet configured to detect impact to identify concussive injuries.

A protective helmet comprising a shell with an internal halo band and a sub assembly comprising of a shock absorber panel located in use intermediate the shell and the head of the wearer over reduce transfer of shock forces encountered by the shell to the head of the wearer. The sub assembly also comprises of framing, secured to the halo band and extending from the halo band to the shock absorber panel to releasably secure the shock absorber panel to the halo. The sub assembly is able to be removed from the shell for cleaning and replacement purposes.

An adjustable helmet includes a first shell, a second shell, and a size adjustment mechanism. The first shell includes a first side portion and a second side portion. The second shell is positioned between the first side portion and the second side portion. The first side portion and the second side portion of the first shell (a) at least partially overlap the second shell and (b) are laterally flexible with respect to one another to facilitate adjusting a size of the first shell between a minimum size and a maximum size. The size adjustment mechanism includes a tensioner extending between the first side portion and the second side portion. The size adjustment mechanism facilitates ratchet-less and infinite adjustment of the size of the first shell between the minimum size and the maximum size without requiring user manipulation of the size adjustment mechanism.

The present invention relates to a helmet and protector elements for protecting a user's head. The helmet being flexible and/or foldable and comprising a head-fitting element (2), having an outer surface and an inner surface, a plurality of protector elements (3) arranged and attached at preselected positions on the outer surface of the head-fitting element to provide a helmet, which has at least a front portion (11), a middle portion (12) and a back portion (13) that are separated by a gap (4). The protector element when attached to a helmet provides an absorption of a force received during an impact to a level reducing the risk of a trauma of a user.
