The present disclosure relates to a rotating body fixing means for a helmet. The rotating body fixing means for a helmet, according to the present disclosure, is provided at the helmet comprising a helmet body (10) and a rotating body (20) rotatably coupled to the helmet body (10), and comprises a fixing part (100), which is slidably disposed at one side of the helmet body (10), slides such that the protruding degree thereof from the helmet body (10) varies, and comes in contact with the rotating body (20) when protruding from the helmet body (10).

A helmet includes a shell having an interior surface, a padding disposed along the interior surface of the shell, and a chinbar. The padding defines a first engagement surface positioned at a first lateral side of the padding and a second engagement surface positioned at an opposing second lateral side of the padding. The chinbar includes a cage, a first flange, and a second flange. The cage includes a first end defining a third engagement surface and a second end defining a fourth engagement surface. The third engagement surface interfaces with the first engagement surface and the fourth engagement surface interfaces with the second engagement surface. The first flange extends from the first end of the cage. The second flange extends from the second end of the cage. The first flange and the second flange of the chinbar are embedded within the padding.

A helmet assembly having a helmet, a mandible guard, and an accessory attachment system that is used to selectively attach and secure the mandible guard to the helmet is disclosed. In some embodiments, the mandible guard is arranged to be detached from a first side of the helmet while remaining secured to a second side of the helmet. In such embodiments, the mandible guard may be moved outwardly and away from a wearer as the mandible guard pivots around the accessory attachment system attached to the second side of the helmet.

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.

A protective helmet including a shell on which are moveably mounted a shield and a chin guard, the chin guard being moveable between a closed position and an open position and having two lateral branches each provided with a guide in which is meshed a guiding finger fixed on the shell, and the shield being moveable between a lowered position and a lifted position and having two lateral arms articulated on the shell, the helmet having an automatic lifting mechanism of the shield configured to lift the shield from the lowered position during the closing movement of the chin guard and including at least a cam-follower system including: a rotary cam secured to a guiding finger pivotally mounted on the shell and connected in rotation to the corresponding lateral branch of the chin guard by cooperation of form with the guide, and a follower element secured to a lateral arm of the shield, wherein the cam and the follower element are at least in partial contact along a given cam surface.

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.

A protective helmet that includes a hard outer shell including an inner surface, a hard inner shell slidingly connected to the hard outer shell where the hard inner shell is spaced apart from the hard outer shell and a leaf spring comprising a center portion anchored onto the hard inner shell, a first end arranged to slidingly contact the hard outer shell, and a second end arranged to slidingly contact the hard outer shell.

Pads on an interior of a helmet contact portions of a wearer's head to secure the helmet to the wearer's head. To simplify removal of the helmet from the wearer's head, an exterior surface of a helmet includes an opening and a pad, or a receptacle plate to which a pad is coupled, includes a fastener opening. The opening in the helmet and the fastener opening in the pad are aligned and a fastener is inserted into the opening in the helmet so fastener is also inserted to the fastener opening in the pad, securing the pad to an interior surface of the helmet. To remove the pad from the interior of the helmet, the fastener is removed from the fastener opening in the pad. As the fastener is accessible from the exterior surface of the helmet, the pad may be removed with minimal movement of the wearer's head.

A contact surface, such as a seating surface on a mandible guard is adjustable such that variations in helmet geometry and/or mandible geometry can be accommodated. The mandible guard may be fixedly attached to a helmet with an attachment arm, yet be configured to permit adjustment of the height of the contact surface to reduce or eliminate a gap between the helmet and a guard portion of the mandible guard. A tilt arrangement may be provided between the attachment arm and the guard portion of the mandible guard to allow a wearer to adjust a pitch angle of the guard portion relative to the attachment arm.

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.
