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 helmet comprises a protective shell, a first energy absorbing layer, a second energy absorbing layer and multiple displace devices. The protective shell forms an outer surface of the helmet. The first energy absorbing layer has a first outer surface and a first inner surface. The first inner surface is configured to couple the helmet to a wearer's head. The second energy absorbing layer has a second outer surface and a second inner surface. The second inner surface faces the first outer surface. The multiple displacement devices are positioned at multiple locations between the first energy absorbing layer and the second energy absorbing layer. The displacement devices allow displacement between the first and second energy absorbing layers in response to an oblique impact to the helmet.

A protective helmet with first and second helmet sections each including an outer shell section and an inner layer section of protective material. The first and second helmet sections are displaceable relative to one another to adjust a size of the helmet. Two opposed side protective members are received inwardly of the outer shell sections on opposed sides of the helmet. Means for adjusting a position of the side protective members relative to the inner layer sections of protective material are provided. The means are configured such that, when the protective helmet is adjusted when on the head of the wearer, the protective members remain substantially stationary with respect to the head of the wearer when the inner layer sections are displaced with the first and second helmet sections.

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).

Helmet including a shell and a half chin bar. The half chin bar can be releasably connected to the shell.

An ambidextrous face guard includes an attachment portion having at least two attachment points. The attachment portion extends from a first end of the ambidextrous face guard toward a second end of the ambidextrous face guard along a slope. The ambidextrous face guard includes a protective portion extending from the attachment portion toward the second end of the ambidextrous face guard along the slope. A line of symmetry extends along at least the attachment portion from the first end of the ambidextrous face guard toward the second end of the ambidextrous face guard such that the line of symmetry defines two symmetric portions of the ambidextrous face guard that each extend along at least a portion of a length of the ambidextrous face guard. The ambidextrous face guard is configured to attach to a right side and a left side of a headgear via the attachment points.

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 relates to a protective helmet (10) comprising an outer shell (12) and a visor (14) removably coupled to the outer shell (12) by means of a fastening mechanism (20) positioned on facing surfaces of the shell (12) and the visor (14). According to the invention the fastening mechanism (20) comprises complementarily shaped elements (22, 24) comprising at least one protrusion (22) and at least one receiving seat (24) provided with a flexible holding portion (26). The at least one protrusion (22) is adapted to be removably fixed inside the at least one receiving seat (24) by engaging the flexible holding portion (26).

A rigid and aerodynamic device for external protection for motorcycle and bicycle vehicles with 2 to 4 wheels. This removable dome type device is formed by multiple overlapping panels that form an oval shell type structure, which protects both the vehicle and the pilot from external weather conditions and physical damage in the event of a collision.
