A head protection system, comprising; a helmet or hat; and one or more pads. The one or more pads are configured to engage the helmet or hat via an engagement mechanism, which may be selected from a hook and loop fastener, an adhesive, and friction snaps. The engagement mechanism may be located on a rear portion of said headwear.

Protective headgear in one case comprises a main body having a pair of side head parts connected by a forehead part and a crown part extending from the forehead part. The body is shaped to encompass the head of a wearer. The main body comprises an inner sheet of an open cell polyurethane foam material, an outer barrier layer, and an intermediate section comprising portions of an open cell polyurethane foam material between the inner and the outer layers. The open cell polyurethane foam has a density of from 100 to 300 kg/m.sup.3 which significantly reduces the G-force energy transferred to a players head during impact.

A flocked helmet cover pad (FHCP) attachable add-on to a helmet cover includes a central hub and multiple appendages attached to the central hub. The appendages are shaped and arranged to provide additional impact energy absorption properties for a helmet.

A helmet configured to protect a human head against mild traumatic brain injury upon impact includes an outer shell and a liner consisting of pairs of fluid fillable flexible fluid chambers fluidly connected to each other by fluid connections between each of the pairs of fluid fillable flexible fluid chambers being spaced on opposite sides of the helmet and configured to fill a space between the head and the outer shell when the helmet is positioned on the head. Impact resistant flexible pads are also inside the liner and are spaced around an inner circumference of the outer shell adjacent to each of the fluid fillable flexible fluid chambers. A flexible inner shell inside the liner is configured to fit closely on the head. The flexible fluid chambers are configured to compress in response to impacting of the helmet on an impact side and to force liquid through the fluid connections to inflate fluid chambers on an opposite side of the helmet thereby cushioning the head against a rebound impact on the opposite side.

A dual functioning head protection device for a fall prone user including a c-shaped neck collar that is configured to compress the jugular veins of the user during application to the user's neck and an expandable airbag helmet that is removably affixed to the collar. The airbag helmet includes an inflatable innerbag surrounded by an outer hag, such that the structure of the outer bag defines a shape of the airbag helmet when the inner bag is inflated. The inner bag includes a number of chambers which inflate to protect the user's skull during a fall. A trigger device in the collar detects if the user is falling and inflates the airbag helmet in such instances. This dual functioning device also protects the user's brain from brain slosh because of the collar's compression of the user's jugular veins. Compression of the vein sends blood into the skull with each fall impact, which reduces the brain's freedom to jostle around in the skull in a fall.

The present invention is a deployable segmented sport equipment for reducing the impact force on sport equipment worn by a user by using deployable panels. The invention has a body defining a recess, and a panel movable within the recess. The panel includes a panel magnetic element capable of being acted upon by a magnetic force. An electromagnet is provided producing an attractive or repulsive magnetic force on the panel magnetic element. A proximity sensing device capable of sensing an object at a distance from the deployable segmented sport equipment is provided with the body. An electronic controller unit receives signals from the proximity sensing device and controls operation of the controllable magnetic element so as to deploy or retract the panel from or into the recess. The panel being deployed prior to impact with the object, with the repulsive force being controlled to absorb the impact force after impact.

The present invention provides a protective headgear having a multi-layered shell to attenuate amplitude of mechanical waves of a blunt trauma to a human head by phase reversal of the mechanical waves at a boundary established between two adjacent layers of the multi-layered shell.

A liner (10) for fitting within a headcap to provide a degree of impact protection, said liner comprising a generally concave shell for receiving a wearer's head, in use, and having a top section (16), a front section (12) and a rear section (14), and a pair of side panels extending downward from, and integrally formed with, respective side edges of said top section (16), wherein a first slot (14a) is provided on each side of said rear section (14), extending from a side edge thereof to a hinge portion (14b) located between said top portion (16) and said rear section (14), and a second slot (12a) is provided on each side of said front section (12) extending from a side edge thereof to a hinge portion (12b) located between said top portion (16) and said front section (12).

A helmet (1) comprising an energy absorbing layer (3), a relatively hard layer (2) that is harder than the energy absorbing layer (3) and is formed outward of the energy absorbing layer (3) and a plurality of outer plates (20) mounted on the outer surface of the relatively hard layer (2); wherein the outer plates (20) are mounted on the relatively hard layer (2) such that, under an impact to an outer plate (20), the outer plate (20) can slide across the relatively hard layer (2) and move relative to other outer plates (20); and a low friction interface is provided between the outer surface of the relatively hard layer (2) and at least a part of the surface of the outer plates (20) that is in contact with the outer surface of the relatively hard layer (2) under an impact to an outer plate (20). FIG. 6 A helmet (1) comprising an energy absorbing layer (3), a relatively hard layer (2) that is harder than the energy absorbing layer (3) and is formed outward of the energy absorbing layer (3) and a plurality of outer plates (20) mounted on the outer surface of the relatively hard layer (2); wherein the outer plates (20) are mounted on the relatively hard layer (2) such that, under an impact to an outer plate (20), the outer plate (20) can slide across the relatively hard layer (2) and move relative to other outer plates (20); and a low friction interface is provided between the outer surface of the relatively hard layer (2) and at least a part of the surface of the outer plates (20) that is in contact with the outer surface of the relatively hard layer (2) under an impact to an outer plate (20).

An energy diverting football helmet is disclosed. The helmet contains the shell having an inside and an outside, padding positioned against the inside of the shell. There is also a face mask attached to the front of the football helmet, and a chin strap. On the outside of the shell there is a plurality of flexible energy divergent baffles (FEDB) attached to the outside of said shell. The flexible energy divergent baffle comprises a base, a flat top, and an offset baffle connecting the flat top with the base. On top of the base is a wafer, upon which resides an energy transferring bumper.
