A helmet liner includes: (a) an open lattice body portion comprised of a polymer, the body portion having opposite face portions and a circumferential side portion; (b) a helmet contact surface portion formed on one of the face portions; and (c) a skin contact portion formed on the other of the face portions, the skin contact portion configured with the lattice body portion so air can circulate through both the body portion and the skin contact portion.

A device for removably connecting a lining layer to an inner shock-absorbing portion of a helmet, mainly made of foam is disclosed. The device includes a first element constrainable to the lining layer and a second element constrainable to the inner shock-absorbing portion. The second element has a threaded portion that can be inserted by screwing it in the foam of the inner shock-absorbing portion. The device also includes means for the mechanical snap-fit coupling between the first and the second element.

A shock absorbing cap provides shock abortion in the space between the interior of a traditional safety helmet and the head of the wearer. The cap has a first region next to the scalp which is made of 100% knitted cotton for comfort and the absorption of sweat. A second region is made of 100% wool fleece braided fiber bundles that extend alternately in longitudinal and lateral directions sufficiently to nearly fill the space. The outermost region is made of one or more layers of braided 100% carbon fiber bundles, which run the opposite direction of the last wool lock. In an alternative, the first region is used but the second region completely fills the space with woven aramid and carbon fiber squares laid on top of each other and sewn together. The uppermost portion is laser cut for a tight but comfortable fit under the helmet.

A protective headgear device for shielding the user from sunlight including a hat having a brim with an outer portion and an inner portion; wherein the inner portion has at least two hat magnets embedded therein and two grommets with opening along said brim; and a single piece of fabric having two side portions, a headband portion and a fabric opening in the middle which fits over the top portion and including at least two fabric magnets embedded therein; where the side portions of the fabric fit through the grommet so that the fabric magnets attach to the hat magnets to secure the fabric across the user's face, neck and shoulders.

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 protective helmet liner apparatus for prevention of head injury, concussions, and brain trauma includes a liner body dimensioned such that a bottom edge sits below a user's skull and a front edge extends from behind the user's ears, over the ears, and across the forehead above the user's eyebrows. A shock-absorptive filling is coupled within the liner body between an inside and an outside of the liner body. A plurality of engagement members comprises a plurality of first engagement members coupled to the outside of the liner body and a plurality of second engagement members coupled to an inner side of a helmet. The first engagement members are selectively engageable with the second engagement members to secure the liner body to the helmet.
