Shock-absorbing helmet liners may be releasably locked to helmet shells using mechanical fasteners.

A helmet with an energy absorbing layer (2) and a sliding facilitator (5) is provided. The sliding facilitator is provided inside of the energy absorbing layer (2). A method of manufacturing a helmet with a sliding facilitator is further provided. The method has the steps of providing an energy absorbing layer in the mold, and providing a sliding facilitator contacting the energy absorbing layer.

A helmet and suit apparatus comprising a helmet with a lens that is connected to a yoke, a neck dam, or other garment via a seal ring assembly. In some embodiments, the apparatus has an air control system permitting air flow into and out of the helmet and for maintaining positive air pressure in the helmet. In further embodiments, the air control system has a series of passages and lens ports that permit air flow on to the inside surface of the lens for anti-fogging purposes, as well as a series of head ports for cooling the wearer's head. The apparatus further comprises a communication system, accessory rails for mounting equipment, and attachment points in the inside of the helmet for receiving hard hats and chin straps as needed.

A protective helmet comprising a shell with an internal halo band and a sub assembly comprising of a shock absorber panel located in use intermediate the shell and the head of the wearer over reduce transfer of shock forces encountered by the shell to the head of the wearer. The sub assembly also comprises of framing, secured to the halo band and extending from the halo band to the shock absorber panel to releasably secure the shock absorber panel to the halo. The sub assembly is able to be removed from the shell for cleaning and replacement purposes.

An impact attenuating helmet including an outer liner having an inner mating surface, an inner liner positioned under the outer liner and having an outer mating surface configured to be received by the inner mating surface of the outer liner, the inner liner and the outer liner being configured to move relative to each other along a slip plane between outer mating surface of the inner liner and the inner mating surface of the outer liner, and one or more securing attachments, each securing attachment being coupled to the outer liner and being configured to secure the outer liner to the inner liner, each securing attachment comprising a slack element configured to permit a range of movement between the outer liner and the inner liner.

A headwear includes an outer covering and an adjustable suspension configured to adjust between a plurality of fit positions. The outer covering sits at a different height on a head of a user in either an upward direction and/or a downward direction for each of the plurality of fit positions when the headwear is worn by the user. The adjustable suspension includes a plurality of straps that each include at least one engagement feature of a first type and at least one engagement feature of a second type. The engagement features of the first type are configured to detachably fasten to one of the engagement features of the second type.

A helmet comprises a crown and a neckband having a body. Right attachment point and left attachment point attach the neckband to the lateral parts of the crown. The body is installed movable between a use position where the body is salient from the crown and a stowed position where the body is installed in the cavity. The inner face of the body is facing the rear inner face of the crown in the stowed position. The body is of curved shape and moves between the positions by turning elastically. The body is connected to the right attachment point and the left attachment point by a flexible attachment formed by a flexible textile element or a strip of elastomer material. The flexible attachment is elastically deformable in three-dimensional manner.

A helmet liner has a central spine, a front panel, and a plurality of arms. First and second side rails each form at least one track. Each of the arms are integrated with the at least one track on one of the first or second side rails. The first end of first and second side rails is secured to the front panel. The second end of each of the first and second side rails forms a cable return channel. Selective lengthening and shortening of first and second loops of cable integrated with a dial system, each loop of the cable being fed through a respective one of the cable return channels at the second end of the first side rail and the second side rail, permits the helmet liner to loosen or causes the helmet liner to tighten, respectively.

A helmet suspension system for use with a helmet shell is provided. The system includes a circular strap barrier configured to encircle a wearer's head below the apex and attached to the helmet shell via one or more shell-connecting straps. A first set of angled straps is connected to the helmet shell and to the circular strap barrier through one or more net-connecting straps, each angled strap forming an arch with one face in contact with the wearer's head. The angled straps act as chords connecting two points on the helmet shell without passing through a central intersection node to enhance tensile resistance to lateral and top-of-head impacts. In some embodiments, a second set of angled straps connects to the circular strap barrier to provide additional multidirectional support.

A helmet suspension system featuring angled straps acting as chords between points on a circular strap barrier or helmet shell, avoiding a central node to enable immediate response to lateral impacts. The system includes a fixed, non-adjustable net integrated with the circular strap barrier for stable head retention without manual adjustment. Straps with distinct tensile strengths, optionally combined with elastomeric components, enhance energy absorption and force distribution across the helmet shell. The design is lightweight, simple, and improves ventilation and comfort without bulky pads or complex mechanisms.
