An electronic motorcycle helmet. The electronic motorcycle helmet includes a helmet having an aperture therein that can receive a head therethrough. A visor is disposed on a front side of the helmet and a display is disposed on an interior surface of the visor. A microprocessor, including a logic that receives a command input directed to one of a plurality of subsystems, toggles the subsystem between an activated state and a deactivated state, and displays a status window on the display corresponding to the subsystem. The plurality of subsystems includes a plurality of cameras disposed about the helmet, wherein each of the cameras is operably connected to the display and can apply a low-light filter for low-light conditions. Other subsystems include a wireless transmitter to wirelessly communicate with an external device, a GPS system, and a battery disposed at a lower edge of the rear side.

A helmet has an inner liner having a body of molded protective material. The body forms an inner cavity adapted to be mounted on a wearer's head to cover portions thereof. An outer shell is secured to and covers the inner liner and forms a generally continuous exposed surface of the helmet. A peripheral edge of the outer shell defines a lower contour of the helmet. Slits are defined in the outer shell and project generally upward from the peripheral edge. Flaps are defined each slit and by material of the outer shell deformed to an open position from a tucked position to open the lower contour of the helmet. A mechanism connects each flap to a remainder of the helmet at least in the tucked position.

A helmet includes a helmet anchor mounted to the helmet, and the helmet anchor includes a cavity. The helmet also includes a first magnetic element, where at least a portion of the first magnetic element is mounted within the cavity. The helmet also includes a visor. An interior surface of the visor includes a receptacle that extends therefrom. A second magnetic element is mounted within the receptacle, and the receptacle on the visor mates with the cavity of the helmet anchor to secure the visor to the helmet. The first magnetic element and the second magnetic element are attracted to one another such that the visor is detachable in response to an impact that exceeds an attractive force between the first magnetic element and the second magnetic element.

A system for optimizing a rider's head position during riding, said system comprising, a headwear comprising, a sensor unit enabling determining in real time a value corresponding to the inclination I.sub.1 of the riders head in the plane defined by direction X and the field of gravity. A processing unit configured to compare the I.sub.1 value in real-time in real time with a reference value I.sub.REF. An output unit, providing an (realtime) output signal to the rider in function of the comparison performed by the processing unit.

An aerodynamic control device includes a void opening. The void opening decreases a resistance of a turbulence generated by a component part located behind a center of a longitudinal width of a helmet and is formed so that one end is connected to the helmet and the other end protrudes backward from the helmet.

A protective helmet (1) comprising a cap (2) having a rear portion on which an aerodynamic deflector (3) is mounted, the protective helmet (1) being characterised in that at least one aerodynamic flap (4) is mounted so as to move freely on the aerodynamic deflector (3) in order to be able to be deployed by aerodynamic forces generated by an air flow. A favoured, non-limiting use of the invention is in the field of motorbike racing.

A helmet includes a helmet anchor mounted to the helmet, and the helmet anchor includes a cavity. The helmet also includes a first magnetic element, where at least a portion of the first magnetic element is mounted within the cavity. The helmet also includes a visor. An interior surface of the visor includes a receptacle that extends therefrom. A second magnetic element is mounted within the receptacle, and the receptacle on the visor mates with the cavity of the helmet anchor to secure the visor to the helmet. The first magnetic element and the second magnetic element are attracted to one another such that the visor is detachable in response to an impact that exceeds an attractive force between the first magnetic element and the second magnetic element.

A helmet with an outer shell, an inner liner, a plurality of vents, and an occipital cliff is disclosed. The outer shell includes an outer surface made up of a first and second surface, the first and second surfaces joined by a drop-off running across the outer surface from a left side of the helmet to a right side of the helmet. A majority of the drop-off is closer to a coronal plane bisecting the helmet than it is to the rear of the helmet. The drop-off is contained within a posterior section of the helmet defined by the coronal plane. The first surface defines a top of the drop-off and the second surface defines a bottom of the drop-off, such that the drop-off has a height. The occipital cliff is located at the rear end of the helmet and is approximately perpendicular to the second surface proximate the drop-off.

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.

An attachment for a helmet includes an external portion, an internal portion distal from the external portion, and a shaft extending between the external portion and the internal portion. The external portion contains an object to be attached to the helmet. An attachment system including a helmet is also described.
