A helmet comprising: inner and outer shells configured to slide relative to each other; and a connector connecting the inner and outer shells so as to allow the inner and the outer shells to slide relative to each other, the connector comprising: an attachment part attached to one of the inner shell and the outer shell; wherein: the attachment part comprises one or more protrusions and the inner or outer shell attached to the attachment part comprises one or more channels into which the protrusions extend, the protrusions and channels are configured such that the protrusions can move within the channels in an extension direction of the protrusions, during sliding of the inner and outer shells relative to each other, and the protrusions comprise an abutment member configured to abut an abutment portion of the channel to prevent the protrusion leaving the channel.

A screen device includes a combiner that shows an image projected by a helmet at the helmet; and a vertical movement mechanism attached to a shell of the helmet, wherein the vertical movement mechanism supports the combiner so that the combiner is movable in a vertical direction and so that an inclination of the combiner is changeable with respect to the vertical direction.

A retention system comprises a shroud configured to be coupled to a helmet. The shroud includes a front surface and a rear surface and the shroud is configured to be coupled to an accessory device. A flexible element is coupled to the shroud and configured to at least partially secure the accessory device to the shroud. The flexible element extends through the front surface of the shroud.

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.

The invention relates to a protective helmet, in particular a protective motorcycle helmet, comprising an outer shell (1) for distributing impact forces, a battery socket (2), which is firmly connected to the outer shell (1), for detachably accommodating a battery (3), and a line assembly (4), which is electrically connected to the battery socket (2), for supplying electricity by means of the accommodated battery (3) to an electric apparatus (5) which is mechanically coupled to the outer shell (1).

A bespoke protective sports equipment to be worn by a player engaged in a sporting activity is provided. The bespoke sports equipment system includes methods for acquiring, storing and processing a player's unique data, namely the anatomical features of the body part against which the bespoke equipment is worn. The systems also includes methods of using the player's unique data to manufacture the bespoke protective equipment with a custom formed internal padding assembly that substantially corresponds to the player's unique data. The system and method allows for the design and manufacture of bespoke protective sports equipment that is purposely designed and manufactured to match the anatomical specifications of the player's body part.

A hard hat with symmetric front and back mounting ridges to support a headlamp is described. The hard hat provides mounting ridges to receive insertion slots of a rigid mounting bracket that fit around the ridges. The rigid mounting bracket includes channels to loop a strap through the channels and support a lamp on the bracket. The strap may include a hook and loop fastener system to enable attachment of a variety of lamps to the rigid support bracket. In this way, the hard hat can support a wide variety of headlamps attached to the rigid mounting bracket without destructive alterations to the hard hat. Clips may be added to the rigid mounting bracket to secure or lock the bracket in place during operation and prevent accidental knocks or jarring of the headlamp.

A clip for a hard hat includes a body having a first end and a second end opposite the first end, a plurality of longitudinally extending fingers formed in the body, and a plurality of slots formed in the body to separate the plurality of longitudinally extending fingers. The plurality of slots is in communication with openings at the second end of the body. The plurality of slots is configured to receive a strap. The clip further includes a hook portion formed in the body at the second end of the body for removably coupling the clip to the hard hat. The hook portion curves toward the first end of the body.

A safety helmet fan system includes a fan housing carrying a first fan on a first side of the fan housing and a second fan on a second side of the fan housing and configured to be mounted, by a mount connector located between the first side and the second side, on an exterior of a safety helmet shell above a brim of the safety helmet shell, and an elongate cooling air duct connected to the fan housing to direct cooling air flow from the fan housing around the brim and into an interior of the safety helmet shell.

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.
