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.

A helmet that includes vents in the shell and removable plugs that may be positioned in the vents to provide an airtight seal while maintaining the aerodynamic shape of the helmet. The vent has an outer vent opening in the outer wall surface of the shell and an inner vent opening in the inner wall surface of the shell. The plug includes a resilient lower surface and an upper surface opposite the resilient lower surface. The resilient lower surface has a lower peripheral lip that compresses when the plug is pushed through the outer vent opening and the inner vent opening and that subsequently expands after the lower peripheral lip passes through the inner vent opening so that the lower peripheral lip engages a portion of the inner wall surface of the shell. The upper surface has an upper peripheral lip configured to conform to a portion of the outer wall surface of the shell when the plug is inserted in the vent.

The present invention relates to a helmet from which pads are removable in case of emergency. The helmet includes a helmet body 100, pads 200 attached to the inside of the helmet body 100, and fastening means 300 detachably attaching the corresponding pads 200 to the inside of the helmet body 100. Each of the fastening means 300 includes a first fastening member 400 in the form of a bar provided on either one of the pad 200 and the inside of the helmet body 100 and a second fastening member 500 provided on the other of the pad 200 and the inside of the helmet body 100, surrounding the first fastening member 400 such that the first fastening member 400 is inserted thereinto, and having an open portion 510 formed at one side thereof. When the pad 200 is pulled out, the first fastening members 400 are separated from the second fastening members 500 through the open portions 510 of the second fastening members 500.

A protective helmet for protecting the head of a user, characterized in that it comprises an enveloping structure consisting of an inner component (1), at least one intermediate component (2) and an outer base component (3) having an annular configuration, where the components (1, 2, 3) are coupled one inside the other, can move in relation to each other from a retracted position to a deployed position and vice versa, and create a space, in a deployed position, corresponding to the part of the user's head that is inside 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 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.

The adjustable safety helmet for motorsports is an item of personal protective equipment. The adjustable safety helmet for motorsports is configured for use in activities involving high velocities including riding motorcycles. More specifically, the adjustable safety helmet for motorsports is a motorcycle helmet. The adjustable safety helmet for motorsports comprises a protective structure, a plurality of rack and pinions, and a plurality of resistance springs. The protective structure further comprises an anterior structure and a posterior structure. The plurality of rack and pinions and the plurality of resistance springs are installed within the protective structure such that: 1) the anterior structure and the posterior structure separate when the protective structure is donned; and, 2) the anterior structure and the posterior structure join to create the protected environment of the adjustable safety helmet for motorsports.

A helmet can include a helmet body comprising an energy-absorbing layer and an outer shell disposed over the energy-absorbing layer. An electronic device can be integrated with the helmet body. A first electrical contact can be formed at an exterior of the outer shell and adapted to be in electrical communication with the electronic device. A helmet visor can be coupled to the helmet body with at least one visor arm, the helmet visor comprising controls integrated within the visor. A second electrical contact can be formed at an inner surface of the at least one visor arm and adapted to be in electrical communication with the controls integrated within the visor. The second electrical contact can be adapted to mateably couple with the first electrical contact such that the electronic device and the controls are adapted to be in electrical contact.

A protective football helmet is provided having a two-piece mold shell diminution shell system. The helmet is comprised of a nine-piece part outer shell, a solid rim outer shell to deflect direct impact from the nine piece part outer shell, an inner liner helmet, compression springs as shocks, and a spin dial to control and restrict the movement of the compression springs and nine piece part outer shell. The nine piece part is a special designed helmet to absorb impact on contact from the crown of the helmet, all four sides and all angles in between to protect the players' head from direct contact at any angle. The outer shell diminution system is piece parted to absorb the impact energy individually by the outer shell protection. Each outer shell piece parted section takes on the impact of energy with an oval shape to deflect and transfer contact impact energy from one piece part to another, thereby dispersing the energy throughout the outer shell of the helmet.
