A protective helmet comprising a helmet shell having at least two layers and the helmet shell having a flexural modulus from 50 MPa to 600 MPa as measured using ASTM D 790 B and a non-foamed specific gravity in the range of 0.916 g/cm.sup.3 up to 1.60 g/cm.sup.3. More than one helmet shell may be combined to provide greater protection to the wearer. The layers may be constructed of an open cell foam, a waterproof coating layer, a separator layer, a flexible layer, a slightly foamed layer, and a cushion layer. A protective facial barrier may be easily removed with use of a locking mechanism which removably secures the facial barrier to the helmet shell. The helmet shells may also be in parts and hinged so that the parts can separate for easy removal of the protective helmet. An adjustment locking mechanism may also tighten and adjust a second helmet shell.

The present disclosure relates to a chin guard pivoting mechanism, and the chin guard pivoting mechanism (100) according to the present disclosure is provided in a helmet which comprises a helmet body (10), a chin guard (20) pivotally coupled to the helmet body (10), and a shield (30) pivotally coupled to the helmet body (10). When the chin guard (20) is pivoted from the front of a user's chin up to a first predetermined angle (A) with respect to the helmet body (10), the shield (30) is pivoted upward, and when the chin guard (20) is pivoted up to a second predetermined angle (B) greater than the first predetermined angle (A) with respect to the helmet body (10), the shield (30) is pivoted downward. Alternatively, when the chin guard (20) is pivoted from the front of a user's chin up to the first predetermined angle (A) with respect to the helmet body (10), the shield 30) is pivoted upward, and when the shield (30) is pivoted downward, the chin guard (20) is pivoted up to the second predetermined angle (B) with respect to the helmet body (10).

Systems and methods are provided for a helmet having a configurable headband assembly. A helmet includes a helmet liner having a plurality of headband attachment points, each headband attachment point including a first opening for receiving and holding a primary attachment structure; and a second opening for receiving a locking pin. A headband assembly is configured to assist in fitting the helmet to a wearer's head. The headband assembly includes a fit adjustment mechanism configured to adjust an internal shape of the headband assembly; and a plurality of attachment structure sets, an attachment structure set including a primary attachment structure; and a locking pin.

A helmet comprises a shell having a front portion, a rear portion, and a pair of lateral portions extending between the front portion and the rear portion. The shell is sized and configured to be placeable on the head of a user. The helmet additionally includes a chin strap having a pair of end portions and an intermediate portion located between the pair of end portions. The end portions are fixedly connected to respective ones of the pair of lateral portions of the shell so as to restrict movement of the end portions relative to the shell. The chin strap is flexible to facilitate placement of the chin strap around a chin of a user in connection with placement of the shell on the head of the user.

A helmet includes a helmet body having a front opening, a closing member attached to the outer side of the helmet body so as to close the opening, and an exterior member attached. The helmet body includes a first outer surface, a first attachment surface to which the closing member is attached, and a second attachment surface which is located between the first outer surface and the first attachment surface and to which the exterior member is attached. The exterior member includes a second outer surface continued to the curved surface shape of the first outer surface, and a side surface. The second outer surface and the side surface form a first angle toward inside of the helmet body. The first outer surface and the second attachment surface form a second angle toward inside of the helmet body. The second angle is larger than the first angle.

A protection device worn on a human body and protects a head of the human body includes a base portion attachable to the human body, and a protection unit having a honeycomb structure or a bellows structure, held by the base portion, and being reversibly switchable between a folded orientation in which the protection unit is folded and an unfolded orientation in which the protection unit is unfolded from the folded orientation and thus the protection unit covers the head of the human body, the protection unit being provided with a fixed end fixed to the base portion and a free end not fixed to the base portion, the protection unit is folded in a state where the free end is close to the fixed end, and the protection unit is unfolded around the head while the free end separates from the fixed end.

A protective headgear can include a core and two or more impact absorbing layers coupled to the core. At least one impact absorbing layer can include a number of impact absorbing components that are configured to absorb and reduce the force of impact incident on the protective headgear. The impact absorbing materials can employ cylindrical segments of viscoelastic foam with a sealed central void to absorb high energy impacts. The protective helmet can reduce the occurrence of concussions and subconcussive impacts to the brain.

A custom-fitted protective sports equipment and a method of making the same can comprise, at a first location, obtaining head data for a customer's head comprising a length, a width, and at least one head contour. With at least one processor, generating a computerized three-dimensional (3D) headform matching the customer's head length, width, and head contour from the head data. The 3D headform can be compared to a safety standard. At a second location different from the first location, the custom-fitted protective sports equipment is formed, wherein the custom-fitted helmet satisfies the safety standard and comprises an inner surface comprising a topography that conforms to the length, width, and at least one contour of the customer's head.
