A helmet for work or sports, including a structure having a substantially convex outer surface and a substantially concave inner surface; a protective body of polystyrene, having a first portion engageable to the inner surface and a second portion having a concavity for receiving the head of a user. The protective body includes: a base element made up of a first material for shock and/or impacts absorption having a predetermined first density value, the base element having a concave surface defining the concavity and a housing cavity facing away with respect to the concave surface; a protective insert made of a second material for shock and/or impact absorption having a second predetermined different density value, preferably lower, than the first density value of the first material, the protective insert being at least partially insertable in the housing cavity.

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 which includes a helmet shell, a protective shield, and at least first and second fastener arrangement which respectively secure the protective shield to opposed sides of the helmet shell, and wherein each fastener arrangement includes a shock absorbing element which is engaged with and secured to a respective section of the protective shield.

A protective helmet includes a shell, which defines a bottom opening and an internal cavity for receiving the wearer's head. The shell further includes a brim with a central opening defined in the brim. An attachment mechanism for securing an accessory to the shell includes one or more openings defined through the brim on either side of the central opening, wherein each of the openings includes a larger diameter portion and a smaller diameter portion, which are separated by a detent. Each opening receives a respective boss of the accessory, which can be selectively advanced from the larger diameter portion to the small diameter portion of the opening. Furthermore, the attachment mechanism includes a slot defined in and along the edge of the shell, with the slot corresponding with the central opening defined in the brim, such that the slot is configured to receive a projection extending from the accessory.

A football helmet including a one-piece outer shell defining an exterior and an interior. The shell includes a plurality of slots penetrating at least partially through the shell from the exterior to the interior of the shell. Each slot may be disposed adjacent to at least one other slot and each pair of adjacent slots defines an energy absorbing beam portion between the adjacent slots. Each beam portion is configured to deform and absorb energy when the exterior of the shell is impacted from a normal direction.

A helmet is described, more specifically a helmet comprising a protective shell (10) formed of a flexible expanded polyurethane (EPU) material which defines a cavity for receiving the wearer's head, the shell being foldable, the helmet further comprising a strap (11) arrangement for fastening the shell to the wearer's head.

A protective helmet system for protecting a user's head including outer and inner shells; a mat including a plurality of cells and a plurality of channels collectively defining a fluid flow system wherein each of the plurality of channels is structured and disposed for connecting adjacent ones of the plurality of cells such that each of the plurality of cells is in fluid flow communication; a fluid in the fluid flow system; and wherein a critical dampening occurs when a force impacts the outer shell at a point of impact causing the fluid to flow away from the point of impact thereby dampening at the point of impact as the fluid flows through the fluid flow system causing each of the plurality of cells on the opposing end of the mat to fill such that motion of the user's head away from the point of impact is decelerated.

Helmet padding systems are disclosed. One helmet padding system includes a rigid shell and a spacing pad. The rigid shell is configured to cover a top of a user's head and be worn under a piece of headgear. The rigid shell includes a pair of slots extending in a direction from a lower rear edge of the rigid shell toward a lower front edge of the rigid shell. The pair of slots define a central portion and opposed side portions of the rigid shell. The central portion includes at least one pair of flaps, with each of the at least one pair of flaps extending outwardly from the central portion into a respective slot. The central portion further includes a tail extending outwardly from the central portion into each of the slots. The spacing pad is positioned within the rigid shell. The spacing pad includes a layer of elastomeric material.

The invention relates to a multi-step method with a number of processes and sub-processes that interact to allow for the selection, design and/or manufacture of a protective sports helmet for a specific player, or a recreational sports helmet for a specific person wearing the helmet. Once the desired protective sports helmet or recreational sports helmet is selected, information is collected from the individual player or wearer regarding the shape of his/her head and information about the impacts he/she has received while participating in the sport or activity. The collected information is processed to develop a bespoke energy attenuation assembly for use in the protective helmet. The energy attenuation assembly includes at least one energy attenuation member with a unique structural makeup and/or chemical composition. The energy attenuation assembly is purposely engineered to improve comfort and fit, as well as how the helmet responds when an impact or series of impacts are received by the helmet.

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.
