The present application discloses a helmet, a retention system for a helmet, and a method of adjusting a helmet. In certain embodiments, the helmet comprises a helmet shell and a retention system attached to the helmet shell. The retention system generally comprises a rear portion connected to the rear of the helmet shell, at least one strap extending from the rear portion to a front portion of the helmet shell, and an adjustment device attached to the rear portion and configured to selectively adjust the length of the strap between the rear portion and the front portion of the helmet shell.

A protective headgear having a protective outer layer, an inner impact dispersing layer, an opening in the posterior of the helmet to allow hair to exit the protective helmet, and juxtaposed to the posterior opening, a flap that covers a portion of the opening and is selectively attachable to the inner impact attenuating layer.

In one aspect, a protective headwear is provided and includes a headgear, an outer shell, a duct and a manifold. The headgear is configured to engage a wearer's head and at least partially support the protective headwear on a wearer's head. The headgear includes a front, a rear opposite the front, a right side, and a left side opposite the right side. The outer shell is coupled to the headgear at a coupling location and includes a shield positioned to the front of the headgear. The duct is at least partially coupled to and at least partially positioned in an interior of the outer shell. The duct is located below the coupling location. The manifold is positioned to the rear of the headgear and configured to divert airflow into at least a first potion of airflow and a second portion of airflow

A sports helmet for protecting a head of a wearer, comprising: an outer shell comprising an external surface of the sports helmet; inner padding disposed between the outer shell and the wearer's head; an adjustment mechanism operable by the wearer to vary an internal volume of the cavity to adjust a fit of the sports helmet on the wearer's head; and a rotational impact protection device disposed between the external surface of the sports helmet and the wearer's head when the sports helmet is worn, the rotational impact protection device comprising a surface movable relative to the external surface of the sports helmet in response to a rotational impact on the outer shell to absorb rotational energy from the rotational impact, the surface of the rotational impact protection device undergoing displacement when the adjustment mechanism is operated by the wearer to vary the internal volume of the cavity.

The present application provides a headband arrangement for a welding helmet, comprising: a fixed attachment structure; and a helmet mounting structure cooperating with the attachment structure, wherein at least two stopping positions are defined longitudinally between the attachment structure and the helmet mounting structure, the helmet mounting structure is selectively switchable between an unlocking state and a locking state, wherein in the unlocking state, the helmet mounting structure is slidable between the stopping positions relative to the attachment structure, and wherein in the locking state, the helmet mounting structure can be locked to one of the stopping positions relative to the attachment structure and can be kept there by a magnetic force generated between a pair of magnetic parts.

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.

A head-mounted display device includes a wearable assembly, at least one cushion and at least one adjustable fixing assembly. The wearable assembly is adapted to be worn on a head of a user. The at least one cushion is floatingly connected to the wearable assembly and contact the head of the user. The at least one adjustable fixing assembly includes a first positioning structure and a second positioning structure. The first positioning structure is connected to the wearable assembly, and the second positioning structure is connected to the at least one cushion. A structural interference generated between the first positioning structure and the second positioning structure positions the at least one cushion to the wearable assembly.

The present invention relates to a functional/multi-purpose head cushion for a headband; the headband is formed from a head cushion comprising: a main body which is depressively formed from up, down, left and right towards the central part; a fixing clip which is provided on the upper part of the main body and is inserted into the band main body or the support band; and banding members for integrally connecting both end portions of the fixing clip and the upper edge portions of the main body, wherein the head cushion is formed from a resilient material so as to have easy shape transformation and resilience and is insert-provided inside the headband and thereby assist in supporting a wearer's head.

Systems and methods of a safety helmet for protecting the human head against repetitive impacts, moderate impacts and severe impacts so as to significantly reduce the likelihood of both translational and rotational brain injury and concussions can be provided. The helmet can include an outer shell, an omnidirectional liner disposed within and coupled to the outer shell and configured to move relative to the outer shell, and a chinstrap coupled to the omnidirectional liner. The chinstrap coupled to the omnidirectional liner can hold a wearer's head to the omnidirectional liner and prevent the chinstrap from applying forces to the wearer while omnidirectional liner moves relative to outer shell. Other embodiments may include a chinguard with a movable chincup.
