Abstract: A helmet for protecting the head of a user may include at least one liner comprising an inner surface and a lower edge surrounding the inner surface at a helmet opening configured to receive a head of a helmet wearer. At least two coupling points may be located on the inner surface proximal to the lower edge. At least one flexible forehead strap may follow the lower edge of the energy management layer and may be inwardly offset from the inner surface. At least two prongs may be coupled to, and slidably extend between, the flexible forehead strap and the at least two coupling points, respectively. A continuous gap between the inner surface and the flexible forehead strap may be provided by an offset created by the at least two prongs, the at least two prongs flexibly maintaining the offset.

Abstract: A safety helmet with a rotary impact buffering function comprises a shell and an elastic liner arranged in the shell, wherein a gap is formed between the shell and the elastic liner, and a rotary impact buffering device enabling the shell to rotate relative to the elastic liner is arranged between the shell and the elastic liner. When the safety helmet is impacted by external force, the shell has the tendency to rotate relative to the elastic liner under the effect of component force applied to the shell in the tangential direction; however, through tangential deformation of the rotary impact buffering device, the shell can rotate relative to the elastic liner by a certain angle on the premise of keeping the elastic liner unmoved, and thus the impact to users from external force is greatly reduced.

Abstract: This application relates to a headgear that provides a moisture wicking mechanism. In various embodiments, a headgear may include a crown with a top, a bottom, a front, a rear, and two sides. In various embodiments, the top, front, rear and two sides may enclose an interior space, open at the bottom. In various embodiments, the bottom may include a perimeter, and the crown may include an outer surface and an inner surface, with the inner surface facing the interior space. In some embodiments, the crown may include multiple sections joined at seams, and the seams may form a convergence at the top of the crown. In some embodiments, a dome comprised of wicking material may at least partially cover the top of the crown, may have a wicking element comprised of wicking material, and may extend through the convergence of seams into the interior space of the crown.
