A helmet can include a helmet body and a shield. The helmet body can include a front portion and a tail portion, and the shield can include two ear portions connected by a brow portion. The shield can be releasably coupled to the helmet body. The ears of a helmet user can be exposed with respect to the helmet body and covered with respect to the shield. The brow portion of the shield can extend across the front portion of the helmet. The tail portion of the helmet can be tapered and the front portion of the helmet can have a rounded leading edge, such that the helmet body has a tear drop form factor.

A safety helmet includes a helmet shell that fits a human head and reaches up to his/her forehead area and a moveable, transparent visor mounted on the helmet shell, wherein an adapter device for attaching helmet attachments is arranged on the helmet shell at the forehead area. A rail leading towards the back of the head designed for the bearing and guidance of the visor is arranged on the adapter device.

A weight compensating bracket to releasably and pivotably mount a protective face shield to a helmet. The bracket has an adapter, which places the pivot of the cap bracket to which the face shield is mounted, rearwardly from the releasable connector to the helmet, enabling the face shield to be well balanced when in the stowed position above the helmet.

An infrared motorcycle helmet device is provided. The infrared motorcycle helmet device includes a helmet. The helmet has an opening on a front portion of the helmet. An external visor is placed on an external surface of the helmets. The external visor can be moved into a position over the opening as desired. An infrared camera is placed on an external surface of the helmet.

A protective helmet including a visor attached to the external sides of the helmet shell. The shell includes substantially flat mount surfaces on each side which correspond with substantially flat portions on the respective ends of the visor. A fastener hole on the shell aligns with an access hole on the visor so that the two elements can be releasably fastened. The access hole provides space for a fastener to protrude out from the surface of the shell, allowing the visor to sit flush against the shell when fastened together. The helmet may include chin straps which are attached to the inner surface of the shell. The helmet may also include a catch strip on the front of the visor which protrudes from the visor such that it can prevent a cloth helmet cover (sometimes used in games such as Roller Derby) from easily sliding off the helmet.

A facial shield for a protective headgear system includes a polymeric sheet having an upper portion configured to be coupled to a support and a lower portion having a lower extremity, wherein the upper portion includes a first hole, a second hole, and a third hole, each one of the first, second, and third holes laterally spaced from the other two of the first, second, and third holes, and the first hole including a first section having a first hole gap and a second section laterally adjacent the first section and having a second hole gap, wherein the first hole gap of the first hole is greater than or equal to the maximum vertical dimension of a first hook of the support, and wherein the second hole gap of the first hole is greater than a vertical base thickness of a base of the first hook and is less than the maximum vertical dimension of the first hook.

A visor has: a visor body defining a visor aperture through the visor body on a side of the visor body; and an attachment device on the side of the visor body to secure the visor to a corresponding one of the flaps of the outer shell of the sport helmet, the attachment device having: a fastener extending through the visor aperture, the fastener having a head facing an outer side of the visor body, the fastener defining first threads threadingly engaged to second threads defined by one or both of the corresponding one of the flaps and a nut secured to the outer shell, and a spacer facing an inner side of the visor body, the spacer defining a spacer aperture in register with the visor aperture, the fastener extending in the spacer aperture at least partially through the spacer.

A protective helmet including a visor attached to the external sides of the helmet shell. The shell includes substantially flat mount surfaces on each side which correspond with substantially flat portions on the respective ends of the visor. A fastener hole on the shell aligns with an access hole on the visor so that the two elements can be releasably fastened. The access hole provides space for a fastener to protrude out from the surface of the shell, allowing the visor to sit flush against the shell when fastened together. The helmet may include chin straps which are attached to the inner surface of the shell. The helmet may also include a catch strip on the front of the visor which protrudes from the visor such that it can prevent a cloth helmet cover (sometimes used in games such as Roller Derby) from easily sliding off the helmet.

A pivoting shield assembly for hats is revealed. The pivoting shield assembly includes mounting slots arranged at two sides of a hat, a pivot base mounted to each mounting slot, a first connecting rod and a second connecting rod each of which having one end pivotally connected to the pivot base and the other end pivotally mounted to a shield, and a pathway groove disposed on an inner side of the first connecting rod. The pivot base includes an elastic locking piece which is mounted and moveable in the pathway groove correspondingly. Thereby lifting up and pulling down of the shield are more precise and having different stages. The pivoting shield assembly for hats is practical.
