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.

The present disclosure relates to a protective device (100) for protecting a head from impact, the device 100 comprising a shell (110) substantially formed in a dome-shape and having a first outer edge (1101); an inner layer (120) substantially formed in the dome-shape disposed within the shell (110), having an second outer edge (1201) and arranged at a gap distance in a direction of in the surface normal of the shell (110), at least one connecting member (130) interconnecting the shell (110) and inner layer (120) by interconnecting the first outer edge (1101) and the second outer edge (1201), an intermediary structure (140) comprising a plurality of deformable elements (1401) arranged in a single layer, wherein each of the deformable elements (1401), in an undeformed state, is arranged in simultaneous contact with the shell (110), the inner layer (120) and at least one other deformable element of the deformable elements (1401).

A helmet includes an outer shell and an impact absorbing layer adjacent to the outer shell. The helmet also includes a fit system mounted to the impact absorbing layer. The fit system includes a rear portion that includes a rotational mount having a ball and an extension mounted to the ball. The fit system also includes a rear mount that includes a plurality of grooves. Each groove in the plurality of grooves is configured to receive the rotational mount of the rear portion of the fit system.

Systems for detecting, locating and mitigating impact forces directed towards a person's head are described herein. The systems include devices for wearing on a wearer's head. The devices include a base configured to conform to the wearer's head and retain a plurality of pouches on an outer surface of the base. The plurality of pouches are configured to absorb at least a portion of the impact force directed towards the outer surface of the base, provide an indication when the impact force directed towards the outer surface of the base has a magnitude exceeding a concussion-indicating level of force, and provide a location of impact when the impact force directed towards the outer surface of the base has a magnitude exceeding the concussion-indicating level of force.

A combat helmet has a shell made from a ballistic rated material, the shell having an outer surface and an inner surface such that at least a portion of the outer surface is formed as a series of adjoining polygon shaped faceted regions that help distribute any force impacted on such regions across a relatively large portion of the shell. The faceted regions are curvedly contoured, and may extend through to the inner surface of the shell. The faceted regions may cover primarily the crown section of the helmet shell, the lower section, or both.

A helmet includes a shell having an interior surface, a padding disposed along the interior surface of the shell, and a chinbar. The padding defines a first engagement surface positioned at a first lateral side of the padding and a second engagement surface positioned at an opposing second lateral side of the padding. The chinbar includes a cage, a first flange, and a second flange. The cage includes a first end defining a third engagement surface and a second end defining a fourth engagement surface. The third engagement surface interfaces with the first engagement surface and the fourth engagement surface interfaces with the second engagement surface. The first flange extends from the first end of the cage. The second flange extends from the second end of the cage. The first flange and the second flange of the chinbar are embedded within the padding.
