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).

A two sided motorcycle helmet that allows the operator to select between a full open face helmet and a fully enclosed face helmet. With the fully enclosed face orientation, a face shield protects the face of the wearer. With the full open face orientation, the wearer's face is open to the elements. A padding layer is provided on an interior surface of a shell of the helmet. A chin strap is operable to secure the helmet to the wearer's head in either orientation.

Helmet including a shell and a half chin bar. The half chin bar can be releasably connected to the shell.

An ambidextrous face guard includes an attachment portion having at least two attachment points. The attachment portion extends from a first end of the ambidextrous face guard toward a second end of the ambidextrous face guard along a slope. The ambidextrous face guard includes a protective portion extending from the attachment portion toward the second end of the ambidextrous face guard along the slope. A line of symmetry extends along at least the attachment portion from the first end of the ambidextrous face guard toward the second end of the ambidextrous face guard such that the line of symmetry defines two symmetric portions of the ambidextrous face guard that each extend along at least a portion of a length of the ambidextrous face guard. The ambidextrous face guard is configured to attach to a right side and a left side of a headgear via the attachment points.

A type variable helmet includes a half face unit formed to cover an upper part of a user's head, and an under face unit detachably attached to a lower part of the half face unit and configured to cover a lower part of the head of the user.

A lacrosse helmet with a plastic shell has a full jaw protector attached to the shell at a right side of the shell and at a left side of the shell, extending forwardly from the shell and extending continuously from the right side of the shell to the left side of the shell and adapted to cover and protect a lower jaw of the wearer. A faceguard made of a grid of horizontal wire members, vertical wire members, and a bottom wire member is removably attached to both the shell and the full jaw protector by loop straps. T-intersections are formed by the bottom wire member and certain of the vertical wire members, adjacent to and above the full jaw protector and forward of loop straps connecting the faceguard to the jaw protector. The loop straps act as stops against rearward movement of the vertical wire members thereby resisting the tendency of the faceguard to slide and twist when struck with blows during sports play.

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 chin guard positioning assembly connects a helmet body and a chin guard to each other. The helmet body provides a certain space to allow a user's head to be inserted thereinto and the position of the chin guard is allowed to be moved from a protective position to an open position. The chin guard positioning assembly includes a movable base part in which a position thereof is moved together with the chin guard. A fixed base part is connected to the helmet body and connected to the movable base part to serve as a reference for the movement of the position of the movable base part. A fixed magnetic force part is fixed to the fixed base part. A movable magnetic force part is fixed to the movable base part to fix the movable base part to a first position or a second position.

Plural contact pieces of a shaft member, which is mounted to a helmet main body, abut a cam surface that is formed at a hole portion provided in a proximal end portion of a chin guard. When the chin guard is rotated from a fully closed position to a fully open position with respect to the helmet main body, at least one of the contact pieces abuts an anchor surface, and, simultaneously, at least another one contact piece fits into a concave portion, and, due thereto, the chin guard is fixed with respect to the helmet main body.

A sports helmet comprises a single-piece plastic shell, an occipital shock absorber attached to the inner surface of the shell in the rear region to at least partially overlie an occipital area of the head, an inflatable occipital pad removably attached to the inner surface of the shell in the rear region and positioned between the inner surface of the shell and the lateral padding assembly to push the occipital shock absorber forward when the occipital pad is inflated. The occipital pad comprises a top sheet and a bottom sheet bonded together, a plurality of inflatable pockets formed in the top sheet and fluidly connected through channels formed in the top sheet, a valve assembly for inflating the plurality of inflatable pockets, the valve assembly bonded to the bottom sheet. The valve assembly extends through a hole in the shell for inflation.
