A hard hat style helmet includes a powered and filtered air intake and distribution system. The air distribution system directs filtered air into a breathing mask structured and located to cover a wearer's mouth and nose. The helmet includes wireless telecommunication features and a speaker and microphone to enable hands-free voice calling. The helmet also includes a camera for transmitting the wearer's field of view. The helmet also includes a transparent display inside the wearer's field of view and another display outside the wearer's field of view.

A helmet having an energy absorbing layer (2) and a sliding facilitator (5) is provided. The sliding facilitator is provided inside of the energy absorbing (2). A method of manufacturing a helmet having a sliding facilitator is farther provided. The method having the steps of: providing an energy absorbing layer in the mould, and providing a sliding facilitator for contacting the energy absorbing layer.

A headlamp with—a headband; a light source located at the front of the headband is presented. The headlamp has a load balancing device with two strands. The first strand has a first end (A) and a second end (B) respectively attached on one left front fixing point and one left rear fixing point of said headband. The second strand has a first end (A′) and a second end (B′) respectively attached on one right front fixing point and one right rear fixing point of said headband. There is an element wherein the first and second strands are thread up so as to bring closer the two strands at one common point C.

The present invention provides a safety helmet inner lining adjustable for suitable wearing, consisting of: a covering body, which has an inner side surface that contacts a user's head and an outer side surface relative to the inner side surface; at least one interlayer pocket, which is disposed on the outer side surface of the covering body; and at least one cushiony pad, which is suitable for placement inside the interlayer pocket. A user is able to place the cushiony pads of suitable thickness into the interlayer pockets at preset positions according to the user's to head shape and dimensions. The inner lining is then put onto the head and a safety helmet put on top. The cushiony pads enable correcting the interspace between the user's head and the safety helmet, thereby allowing suitable and perfect fitting of the safety helmet that ensures safety of the wearer.

A skull mounting system for headgear, preferably a respirator hood, includes a headband with a front headband and a rear headband. The front headband extends around at least the front of the head of the wearer and the rear headband is found on the back of the head of the wearer, and at least one upper headband is provided that extends over the top of the head of the wearer. The upper headband has higher elasticity than the front and rear headbands.

A skull mounting system for headgear, preferably for a respirator hood, is described. The skull mounting system comprises a headband with a front head strap, which extends around the front of the head of a wearer, and a rear head strap, which is found on the back of the head of the wearer. The rear head strap is connected to the front head strap by means of two swivel joints. The swivel joints are at least partially freely rotatable in a corresponding adjustment position and are not rotatable in a corresponding locked position.

Various embodiments are directed to a protective helmet comprising: a protective shell having a substantially dome-shaped configuration, the protective shell comprising: an outer shell surface; an inner shell surface; and at least one groove extending along at least a portion of the inner shell surface, wherein the at least one groove is embodied as a material recess within a wall thickness; wherein a ratio of the shell thickness at a first shell location adjacent the at least one groove to the groove depth of the at least one groove is at least a predetermined threshold value. In various embodiments, a protective helmet may further comprise an impact cap and/or an inner ring, one or both of which may comprise a respective groove configuration. In various embodiments, the one or more groove configurations may be configured to reduce the helmet weight of the invention by at least 15%.

A protective helmet includes a head support fixed to a crown. The head support forms a U shape with a frontal part fixed to the frontal part of the crown. The two ends of the head support are fixed to the side walls of the crown via two attachment points. First adjustment parts adjust the length of the head support between the two attachment points and the distance separating it from the frontal part of the crown. A neckband is fixed to the occipital part of the crown and is fitted in movable manner. Second adjustment parts of the neckband adjust the distance between the neckband and the frontal part of the head support.
