The present disclosure relates to a variable helmet that can be unfolded flat and carried or kept when not in use. A configuration of the variable helmet is characterized by including a protective pad in which a plurality of unit pads are planarly coupled like a mosaic so that the protective pad is in a hemispherical shape to cover and protect a head of a wearer and is able to be unfolded flat like a plate, the protective pad having unevenness portions provided in a sawtooth shape at both ends thereof; both-end fixing means allowing the unit pads to have a hemispherical shape by tightening the both ends of the protective pad; and a chin strap allowing the protective pad to be fixed in a state in which the protective pad is covered on the head.

A collapsible protective helmet (10) comprises an impact-resistant base body (11) intended to encircle the head of a wearer and an impact-resistant crown (12) coupled to the base body by coupling means to be movable between a protective position in which the crown is supported by the base body in an orientation in which the crown covers the top of the head of the wearer and a stored position inverted relative to the protective position in which the crown is supported by, but nested in, the base body. The helmet further comprises releasable locking means for locking the base body (11) and crown (12) together in each of the two positions of the crown. The coupling means permits movement between those positions by pivotation of the crown relative to the base body in a direction away from the base body so as to no longer be supported by the base body rotation of the crown relative to the base body through substantially 180 degrees and pivotation of the crown relative to the base body in a direction towards the base body so as to again be supported by the base body.

An impact-attenuating liner for a helmet includes a liner body made from an impact-absorbing material and a plurality of pads removably attached to an interior surface of the liner body, each of the pads being repositionable at different locations on the interior surface of the liner body. A retention system may be attached to the liner body and configured to secure the liner to the wearer's head during use. The liner may be configured to provide substantially uniform impact protection throughout the interior region of the helmet.

Disclosed are devices and methods for optimizing a protective helmet or other item of protective clothing with one or more enhanced principal impact zones and/or impact elements that incorporate protective features that can be particularized to a specific player-position and/or the individual behavior of a specific player or wearer.

A personal protection system for providing a sterile barrier around medical/surgical personnel. The system includes a helmet over which a hood or a toga suspended. A microphone, an amplifier and a speaker are mounted to the helmet. Speech of the individual wearing the personal protection system is picked up by the microphone and amplified speech is broadcast by the speaker. The speaker is outwardly directed so as to broadcast the speech out through the hood or toga covering the helmet.

A forehead support band for work or sports protective helmets, having an elongated structure, and able to assume an arched configuration in the mounted condition on a respective helmet is provided. The structure has at least one fixing appendage, for its fixing to the helmet, interposed between two opposite ends of the structure. The band has two movable connection brackets for the engagement of the structure to the helmet and to a size-adjustment device arranged to engage a user's nape.

A helmet according to the present invention includes: a head frame being open toward the user's face, designed to cover the user's head, and having a rotation part at both sides; a face frame coupled to be turned up and down about the rotation parts and selectively closing the opening of the head frame; and a sun visor disposed at an upper portion of the face frame and coupled to be turned up and down about the rotation parts, in which the sun visor is turned up with the face frame when the face frame is turned up to open the opening of the head frame, and is fixed regardless of rotation of the face frame when a predetermined rotational limit is reached.

A folding hat can include an integrated display system. Methods for folding and manufacturing the hat with integrated displays are also disclosed. The hat can include a visor and cap of various materials integrated with displays. The hat can have hinges that fold the assembly into a small volume for stowing. The hinges are configurable in a multitude of positions and geometries to provide different folding techniques and folded geometries. Such configurations allow for a range of options for carrying and storing the folding hat with integrated display system.

An adjustment mechanism and headband arrangement are disclosed herein, the adjustment mechanism including an elongated cord configured for extending around a perimeter of the headband arrangement; and a locking member receiving a portion of the elongated cord and configured to interact with the elongated cord between a locked state, preventing movement of the elongated cord relative to the locking member, and an unlocked state, permitting movement of the elongated cord relative to the locking member, wherein the locking member comprises at least one tooth configured to engage the portion of the elongated cord received in the locking member in the locked state, and wherein the portion of the elongated cord is configured to disengage from the at least one tooth in the unlocked state in response to at least one of the first end and the second end being pulled in the direction of the major longitudinal axis.

The hard hat with integrated electronic systems is a hard hat comprising a shell, headband, sweatband, suspension harness, and size adjustment ratchet and knob. The hard hat also comprises electronics, which allow the user to listen to radio broadcasts, determine the time, receive and initiate mobile phone calls, issues voice commands to a paired device, or combinations thereof. A pair of audio transducers mounted adjacent to the ears allows the user to hear radio broadcasts and mobile phone audio. A microphone mounted on the control panel allows the user to talk during a mobile phone call or speak voice commands. A microprocessor within the hard hat controller manages devices and routes signals. A control display and operator controls accessible on the exterior side of the hard hat allows the user to change settings and pair the hard hat with a smart phone.
