A helmet shield opening mechanism is provided, wherein first and second constraint tracks are provided on at least one support leg of a shield jaw guard, and a driver element is configured to come into contact with and drive the two tracks, so that the helmet has forced and controlled modes relative to the opening action and process of the helmet body. On one hand, the operational reliability and flexibility of the shield opening mechanism can be improved; on the other hand, the shield is opened smoothly without collision, thus improving the wearing comfort of the helmet. Further, a helmet with changeable jaw guard equipped with the helmet shield opening mechanism can plan the opening process of the shield flexibly to adapt to states of the jaw guard at different operation positions, thereby greatly reducing the chances of collision between the jaw guard and the shield.

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.

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.

A helmet assembly includes a face shield and a single, center top mounting arrangement that operatively connects a center top location of the face shield to a center front mount on the helmet. The face shield can be raised and lowered about a pivot axis provided in the mounting arrangement between a tilted up, non-use position and a lowered, deployed position. The mounting arrangement can include a detent and two recesses, wherein the detent engages a first recess at a slightly forwardly displaced position to allow ventilation between the helmet and mandible and the face shield and a second recess at the tilted up, non-use position. The recess and detent engagement can be overcome by easy manual force acting on the face shield to reposition the face shield.

A protective helmet, including a hard outer shell, a hard inner shell slidingly connected to, and spaced apart from, the outer shell, and a leaf spring including a center portion, a first end, and a second end, the leaf spring anchored only at the center portion onto the hard outer shell, the first end unattached to, and in sliding contact with the hard inner shell, and the second end unattached to, and in sliding contact with the hard inner shell. In a neutral position, the first end is spaced from the second end by a first distance, and when a force strikes the helmet, the first end is spaced from the second end by a second distance, the second distance being different from the first distance.

A protective football helmet is provided having a face guard mounting system with at least one pair of opposed recessed mounting regions that ensure a low-profile mounting arrangement for a face guard to the helmet. The recessed mounting regions are formed in both the inner and outer surfaces of the helmet shell along a frontal opening in the shell. As a result of the streamlined frontal appearance provided by the face guard mounting system, the width of the face guard closely corresponds to the width of the helmet at the recessed mounting regions.

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).

The invention discloses a helmet with associated rotation of a chin guard and a face mask, comprising a helmet body, wherein the face mask and the chin guard are symmetrically hinged to a mounting groove at a side surface of the helmet body, the mounting groove is provided with a face mask rotation limiter, a face mask mount, a linkage guide annular piece connected with the face mask mount, a driving rod matched with the annular groove on the linkage guide annular piece, a chin guard mount connected with the driving rod via hinging pieces, and a chin guard rotation guide clamped on the driving rod and the chin guard mount, wherein a double-track guide groove for guiding the rotation of the chin guard is formed in the chin guard rotation guide, and the hinging pieces provided at two ends of the driving rod respectively pass through the double-track guide groove and are connected with the chin guard mount; wherein the face mask rotation limiter is mounted on the mounting groove by a connector, and the linkage guide annular piece is hinged with the chin guard rotation guide by a first rotating shaft; and the chin rotation guide is connected with the mounting groove by a connector.

The invention relates to a protective helmet with an outer shell (1) for distributing impact forces, an interior layer (2) accommodated by the outer shell (1) for attenuating impact forces, and a slot (3) for accommodating an electrical device (4), wherein the outer shell (1) has a chin shell area (6) to cover a chin portion of a protective helmet wearer, wherein the outer shell (1) forms a viewing port (8) for the protective helmet wearer to look through. The protective helmet is characterized in that the slot (3) is arranged on the chin shell area (6) in such a way that the accommodated electrical device (4) is arranged between the chin shell area (6) and the interior layer (2), wherein the protective helmet has an interior cover (10) for essentially completely covering the accommodated electrical device (4) in the direction of the viewing port (8).
