The invention relates to an internal protection device for a helmet (2) comprising a hard outer shell (4), a flexible inner cap (6) arranged inside the shell (4), and a chain of air cushions (8) designed to be placed inside the helmet (2), between the head that is to be protected and the flexible inner cap (6). The flexible inner cap (6) comprises a layer of thickness (E) within which there is created a plurality of cavities (100-n) of which the shape, number, respective depth (P) and arrangement are chosen, dimensioned and combined with the air cushions (10-n) so as to improve the shock absorbing properties of the helmet and cover the parts of the user's head that are to be protected when the air cushions (8) are filled with air, while allowing simple removal from the helmet when the air cushions are deflated.

A protective sports helmet that includes a chin strap system that allows for rapid, one-handed adjustment of a chin strap assembly by the player while he/she is wearing the helmet is provided. The chin strap assembly includes a protective chin cup and a pair of straps extending from opposed sides of the chin cup and having a plurality of securing elements. The assembly also includes a pair of adjustable connectors affixed to the helmet and that include a central opening that receives an extent of the strap and a lever that engages a portion of the securing elements. The adjustable connector allows movement of the strap in a first direction, and prevents movement of the strap in a second direction when the lever is engaged with at least one of the securing elements. The adjustable connector allows movement of the strap in both the first and second directions when the lever is not engaged with the securing elements.

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.

The present disclosure provides a helmet that includes a segmented outer shell comprising a plurality of independently movable segments. The helmet also includes internal layers that comprise flexible bearings and other optional padding to provide mobility to the segmented outer shell and to provide impact protection via force dispersion and compression of the layers of the helmet. In a first embodiment, the bearing is a substantially hemispherically-shaped node. In a second embodiment, the bearing is a substantially torus-shaped pad.

A helmet tool including a housing; a pin at least partially disposed in the housing; a trigger mechanism operatively engaged with the pin, wherein the pin and trigger mechanism may be configured together within the housing such that actuation of the trigger mechanism causes the pin to one of extend from or retract into the housing; and a latch connected to the housing.

The present invention relates to a protective helmet (1) comprising: an outer shell (10); an impact absorbing liner (12), positioned inside the outer shell (10), and a comfort liner (14), positioned at an inner surface of the impact absorbing liner (12), so as to be in contact with the user's head during the use of the protective helmet (1). The comfort liner (14) comprises at least one cheek pad (16) including a padding layer (18) and a pad back plate (20). The at least one cheek pad (16) is coupled to the impact absorbing liner (12) by means of magnetic coupling means (22, 24) provided at the interface surface (P) between the pad back plate (20) and the impact absorbing liner (12). The magnetic coupling means comprise at least one projection (22), provided with a first magnetic element (26), designed to be inserted inside at least one recessed seat (24) in proximity of which a second magnetic element (28) is arranged. According to the invention, the at least one recessed seat (24) has a different size and shape with respect to said at least one projection (22). Said at least one projection (22) is adapted to move inside said at least one recessed seat (24) between a first position, wherein the first magnetic element (26) and the second magnetic element (28) are faced to each other, and a second position, wherein the first magnetic element (26) and the second magnetic element (28) are spaced apart, so that the pad back plate (20) is releasable from the impact absorbing liner (12).

A helmet removal system includes a detachable helmet liner configured to be positioned in a helmet. The helmet liner includes a central portion configured to receive a user's head therein, a frontal portion integrally formed with the central portion and configured to engage a user's frontal head portion. The helmet liner further includes dual side tab portions integrally formed with the central portion. The dual tab portions are configured to be moved between a folded position, inside of the helmet, to an unfolded position. The helmet liner further includes a top portion extending between opposing edges of the central portion. The helmet liner also includes a rear portion integrally connected to the central portion to provide balanced engagement with the back of a user's head. Helmet removal is achieved by applying lateral pulling forces to the dual tab portions.

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 detachable pad fastening structure of a helmet includes a first fastening unit, which includes a first fastening member having a fastening hole formed therein and is disposed at an inner surface of a helmet main body. A second fastening unit includes a through-hole in the form of a slot in a detachable pad and a second fastening member formed to be movable relative to the through-hole, having at least a part protruding toward the outside of the detachable pad so as to be inserted into the fastening hole when the second fastening member is located at one side of the through-hole, and configured to be inserted toward the inside of the detachable pad so as to be removed from the fastening hole when the second fastening member is moved relative to the through-hole toward the other side of the through-hole.
