A ballistic helmet comprising a ballistic shell, wherein within the thickness of the ballistic shell, or inside the ballistic shell, there is provided one or more circuit layers forming a circuit, which circuit comprises a power bus and a data bus, and wherein one or more power connections and one or more data connections are provided on the inside and/or on an edge of the ballistic shell for providing power and data to/from one or more electrical devices through the circuit.

The present disclosure relates to a dual helmet that can be easily converted into two sets of helmets having protective cushioning, and which are comfortable, yet strong, safe, and up to the required standards. The helmet includes a first shell and a second shell defining a shell of a first helmet and a second helmet, respectively. The second shell is removably disposed over the first shell such that the helmet can be used as a single combine helmet when the shells are together, and further, the second shell can be separated from the first shell to form two separate helmets. The helmet includes a first cushion disposed within the first shell, and a second cushion for the second helmet being removably configured within the first cushion such that the second cushion can be separated by slightly bending it, and later can be configured with the second shell to form the second helmet and the first helmet, as required.

A modular helmet system comprises a helmet and a chin bar detachably mountable to the helmet. The helmet comprises two receiving-brackets. The chin bar may be inserted into the receiving-brackets of the helmet with its two ends in front in a substantially straight line, wherein the chin bar is lockable in the receiving-brackets in an end position. Each of the two receiving-brackets comprises two insertion flanks which extend towards each other along the direction of insertion at an acute centering angle, wherein the insertion flanks are configured to center the chin bar in the vertical direction when being inserted and to form a stop for the chin bar in the end position of the chin bar.

A protective football helmet is provided having a one-piece molded shell with an impact attenuation system. This system includes an impact attenuation member formed in an extent of the front shell portion by removing material from the front portion. The impact attenuation member is purposely engineered to change how the front portion responds to an impact force applied substantially normal to the front portion as compared to how other portions of the shell respond to that impact force. In one version, the impact attenuation member is a cantilevered segment formed in the front portion of the shell.

The present disclosure relates to a locking means for chin guard, and the locking means for chin guard according to the present disclosure is equipped in a helmet including a helmet body (10) and a chin guard (20) rotatably coupled to the helmet body (10), and includes a first fastening portion (100) formed in any one of the chin guard (20) and the helmet body (10), a second fastening portion (200) formed in the other one of the chin guard (20) and the helmet body (10), and into which the first fastening portion (100) is inserted, and a shutter portion (300) covering the second fastening portion (200), wherein when the first fastening portion (100) is inserted into the second fastening portion (200), the shutter portion (300) opens the second fastening portion (200).

The present disclosure relates to a helmet, and the helmet according to an embodiment of the present disclosure includes a chin curtain (100) disposed at a chin guard (20) of a helmet body (10), wherein the chin curtain (100) rotates with respect to the chin guard (20).

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.

The present disclosure relates to a chin guard pivoting mechanism. The chin guard pivoting mechanism according to the present disclosure is provided in a helmet including a helmet body (10) and a chin guard (20) pivotally coupled to the helmet body (10), wherein while two connectors (100, 200) provided in the chin guard (20) move along two guide parts (300, 400), the chin guard (20) is pivoted, and at least one (400) of the two guide parts (300, 400) extends from the front to the rear.

A full-face helmet for use in sport is provided. The helmet comprises a rigid outer shell for fitting about a top, back and sides of a user's head, and a detachable chin guard for partially covering a user's face. The detachable chin guard is magnetically connected to the sides of the rigid outer shell. A secondary fastening means is provided on the chin guard as a pair of hinged clips.

A helmet includes a shell and a half chin bar releasably connected to the shell. The half chin bar is selectively connectable and disconnectable to and from the shell by means of an attachment device. The attachment device includes a coupling portion and a manual drive portion for the complete release of said coupling portion. The manual drive portion is accessible from the outside of the shell and/or the outside of the half chin bar.
