A safety helmet with retractable brim comprising a helmet shaped body having a slot presented on a downward facing surface of a front section. The safety helmet includes a brim that translates within the slot between a retracted and a downward configuration. In the retracted configuration the brim is received within the slot. In the downward configuration the second end of the brim does not extend beyond the forward facing surface of the helmet. A pivoting element is configured to pivotally couple the brim proximate to the lip of the slot. The pivoting element allows the brim to move between the downward configuration and a forward configuration. In the forward configuration the brim extends outward beyond a forward facing surface of the helmet shaped body. A first locking element is configured to maintain the brim in the forward configuration.

A helmet including a helmet shell for receiving a head of a wearer, the helmet shell defining therein: a connector chamber, and a connector aperture opening into the connector chamber; the connector chamber being shaped and configured to receive therein an anchor portion of at least one accessory, the at least one accessory being chosen from: a power connector for selectively powering the helmet; a garment for selectively powering the helmet; and a storage fixation for selectively receiving the helmet for storage, the helmet being configured to selectively secure the at least one accessory thereto by receiving the anchor portion of the at least one accessory in the connector chamber.

Some embodiments provide a visor brim including a visor brim body and an optical filter configured to attenuate visible light in certain spectral bands. At least some of the spectral bands can include spectral features that tend to substantially increase the colorfulness, clarity, and/or vividness of a scene. In certain embodiments, headgear incorporates an optical filter that enhances chroma within one or more spectral bands. In some embodiments, a wearer of the headgear can perceive the increase in chroma when viewing at least certain types of scenes. In some embodiments, a wearer can combine chroma-enhancing headgear and chroma-enhancing eyewear to view complementary chroma enhancement.

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.

A protective eyewear apparatus can include a coated visor and an anchoring element configured to removably secure the coated visor to a wearer's head. The coated visor may comprise a visor with a viewing area and a multi-layer visor coating film comprising a protective film and an adhesive layer unreleasably coupled to the protective film and releasably coupled to the visor viewing area. The multi-layer visor coating film may alternatively be included in a visor protection application kit that may additionally comprise a surface treatment solution, an adherence uniformity tool, and instructions for releasably coupling the multi-layer visor coating film to a viewing area of a visor portion of a protective eyewear apparatus. In addition, a method is provided for imparting abrasion resistance, puncture resistance, resistance to tearing, and corrosion resistance to a protective eyewear apparatus.

A shield for a helmet includes a shield having a sun visor rotatably and axially supported at a position different from a rotation center of the shield. The sun visor rotates within a range from a first position where the sun visor, like a bill of a hat, lies above a front opening part and projects forward to a second position where the sun visor lies outside facing the shield in an overlapping manner, and the sun visor is retained in the first position. The sun visor is operated and moved forward and away from the shield to rotate from the first position to the second position.

A method for training an athlete to adopt a vertical head-up position includes: placing a visor comprising an opaque region over the face of the athlete such that the opaque region of the visor blocks the upper peripheral vision of the athlete if the athlete lowers his/her head below the vertical head-up position; and having the athlete train with the visor over his/her face to teach the athlete to keep the head in the vertical head-up position, thereby minimizing a risk of head-to-head contact with another athlete during a game. An apparatus for training an athlete to adopt a vertical head-up position is also described.

A visor removably attached to a helmet includes a brim, a first wing extending from the brim, a first prong from the first wing engaging with the first side vent. A second wing opposite the first wing extends from the brim, a second prong from the second wing engaging with the second side vent. A distance between the first prong and the second prong is smaller than a distance between the first front wall of the first side vent and the second front wall of the second side vent, the first prong and the second prong respectively engaged with the first side vent and the second side vent through tension in the visor resulting from expansion of a wingspan between the first wing and the second wing.

A foldable helmet is provided. The helmet includes a plurality of struts hingedly interconnected thereby enabling the struts to splay out from a closed packed state. Each strut includes a hinge along a length of the strut for folding the strut and a plurality of cutouts allowing the strut to bow in a direction opposite a fold direction of the hinge.

A helmet with an outer shell, an inner liner, a plurality of vents, and an occipital cliff is disclosed. The outer shell includes an outer surface made up of a first and second surface, the first and second surfaces joined by a drop-off running across the outer surface from a left side of the helmet to a right side of the helmet. A majority of the drop-off is closer to a coronal plane bisecting the helmet than it is to the rear of the helmet. The drop-off is contained within a posterior section of the helmet defined by the coronal plane. The first surface defines a top of the drop-off and the second surface defines a bottom of the drop-off, such that the drop-off has a height. The occipital cliff is located at the rear end of the helmet and is approximately perpendicular to the second surface proximate the drop-off.
