A helmet includes an operation mechanism, which is accommodated in an accommodation portion, on an outer shell of the helmet for operating an anti-glare visor with a transmission cable. One wall surface at an end of the accommodation portion in an operation direction defines an end surface including an insertion hole extending through the outer shell for passage of the transmission cable.

The present disclosure relates to a rotating means for a helmet, and the rotating means for the helmet according to the present invention comprises a rotary shaft (100) which allows a shield (30) to be rotatably coupled to a helmet body (10) so that an opening portion (20) of the helmet body (10) is opened/closed by the shield (30), and when the shield (30) is rotated in the direction of closing the opening portion (20), the rotary shaft (100) is moved to the rear direction with respect to the helmet body (10).

A helmet may include: a brain wave detector configured to detect a brain wave of a user; a sound input configured to receive sound; a sound output configured to output sound; and a controller configured to, in response to detecting the brain wave of the user, compare the detected brain wave with a previously stored brain wave, to activate a dialogue mode when the detected brain wave matches the previously stored brain wave, to recognize a speech from the sound received by the sound input, to generate a dialogue speech based on the recognized speech, and to control the sound output so as to output the generated dialogue speech.

A helmet mounted visor includes a lens that may be configured to extend across substantially all of a user's face. The helmet mounted visor may include a pair of mount arms coupled to the lens and each configured to releaseably mount to a mount attached to a helmet. The pair of mount arms may each including first, second and third portions. The first portion may be rotatably coupled to the second portion about a first axis. The first portion may be rotatably coupled to the third portion about a second axis. The second axis may be generally perpendicular to the first axis. A locking mechanism may be provided and configured to selectively retain the first portion relative to the second portion in and between a use position where the lens is positioned in front of the user's face and a stowage position where the lens is positioned proximate the top of the helmet.

A helmet has a helmet shell and a visor pivotally connected to the helmet shell. The helmet further has an electrical device attached to the visor. First and second helmet electrical contacts are attached at both sides of the helmet and are adapted for electrically connecting to an electrical power source. First and second visor electrical contacts are attached to each side of the visor and are electrically connected to the electrical device. The first and second visor electrical contacts are pivotally connected to the helmet shell about first and second pivot axes passing through the first and second helmet electrical contacts respectively. The first and second visor electrical contacts are in contact with the first and second helmet electrical contacts respectively, at all positions of the pivoting visor.

Visor for a protective helmet, having two retaining arms and two bearing devices for the retaining arms which are attached to a helmet shell of a helmet in order to pivot the visor between two end positions corresponding to an operational position and a parked position in which the visor is folded up and is disposed on the outer surface of the helmet shell. The visor is provided with a soft lip, preferably made from TPU or TPE, at the location where it comes into contact with the helmet shell in the end positions. When the visor is manually activated to pivot out of an end position, the visor is accelerated by resilient pretensioning in the direction of the other end position until the lip is in contact with the helmet shell substantially without recoil. The lip damps the movement momentum of the visor and additionally has a sealing function.

Visor assembly (1) comprising an outer shield (2) and an inner shield (6) which is arranged at a distance therefrom and lies within the periphery of the outer shield, wherein a spacer (7) extending along the periphery of the inner shield is provided in order to hold the inner shield at a predetermined distance from the outer shield, wherein mechanical fixing means (10, 12) are arranged between the two shields for mutual fixation thereof, wherein the inner shield is formed at the position of its periphery such that a protrusion (7) from the inner shield is obtained, this protrusion forming the spacer.

A visor (26) for a helmet (22) comprises: an air delivery element (34) for delivering air to a surface of the visor (26). The air delivery element (34) comprises: at least one inlet (28) for receiving air from an air source (30); and a plurality of outlets (44) through which air is transportable to the surface of the visor (26). The visor (26) may also include a ridge (84) formed adjacent to the plurality of outlets (44) for creating a Coanda effect in air passing through the plurality of outlets (44).

Described herein is a self-cleaning visor (1) comprising: a support structure (2) having a see-through portion (2a); an endless transparent film (3); a film drive means (4); and at least one film cleaning means (5); and two fasteners (6). The support structure (2) is releasably attachable to an associated helmet (10) by the two fasteners (6) such that it is tiltable between a raised see-through position (A) and a lowered see-over position (B). The support structure (2) encloses the endless transparent film (3) except for at the see-through portion (2a). The support structure (2) comprises the film drive means (4) and the at least one film cleaning means (5). The support structure (2) supports the endless transparent film (3) to selectively be driven by the film drive means (4) in a continuous loop over the see-through portion (2a) and past the at least one film cleaning means (5).

Disclosed is a pivot mechanism for a shield for a helmet, the pivot mechanism comprising a curved track having a first end and a second end; and a clamp slidingly engaged to the curved track, wherein the clamp is configured to attach to an end of the shield and slide along the track between a first position proximate to the first end of the curved track and a second position proximate to the second end of the curved track.
