The emergency protective helmet includes a storage support worn about the neck, a series of curved elements mounted movable in rotation with the storage support worn about the neck and with each other at their ends so as to be able to switch between a first, functional deployed position, in which the curved elements form a protective structure, and a second, non-functional stowed position, in which the curved elements are housed in the storage support worn about the neck, the emergency protective helmet further including a compressed gas cartridge and a set of flexible tubes fluidically connected to the cartridge and connecting the curved elements to each other, the flexible tubes being arranged such that inflating the flexible tubes switches the curved elements from the second, stowed position to the first, deployed position.

A collapsible protective helmet (10) comprises an impact-resistant base body (11) intended to encircle the head of a wearer and an impact-resistant crown (12) coupled to the base body by coupling means to be movable between a protective position in which the crown is supported by the base body in an orientation in which the crown covers the top of the head of the wearer and a stored position inverted relative to the protective position in which the crown is supported by, but nested in, the base body. The helmet further comprises releasable locking means for locking the base body (11) and crown (12) together in each of the two positions of the crown. The coupling means permits movement between those positions by pivotation of the crown relative to the base body in a direction away from the base body so as to no longer be supported by the base body rotation of the crown relative to the base body through substantially 180 degrees and pivotation of the crown relative to the base body in a direction towards the base body so as to again be supported by the base body.

A bicycle helmet that fits over a surface of a head of a user generally includes a segment of flexible cell structures that form a radial honeycomb matrix movable between a folded condition where each side of the segment is disposed generally parallel and an expanded condition where the radial honeycomb matrix of the segment is configured to be expanded at least partially over the head of the user and arranged radially relative to the surface of the head of the user. The bicycle helmet includes a first and second side frame disposed respectively at the first and second ends of the honeycomb matrix. A sliding latch permits selective translation of the first and second side frames.

A helmet which has a plurality of substantially longitudinal members arranged side-by-side, the longitudinal members being in fluid communication with each other. It has a first inflated state in which the longitudinal members are distributed to form a substantially concave shape, and a second compressed state in which the longitudinal members lie flat and substantially coincident against each other. Each longitudinal member is separated from neighbouring longitudinal members by a tubular connecting member in a lattice configuration. The helmet may be made of HDPE or nylon.

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 inner bag surrounded by an outer bag, 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.

A personal protection system for providing a sterile barrier around medical/surgical personnel. The system may include a head unit over which surgical garment such as a hood or a toga may be suspended over. The surgical garment may include a sterile material and a shield configured to be disposed in front of the wearers face when disposed over the head unit. The shield may comprise an anti-reflective coating configured to reduce the glare observed by the individual through said shield. The head unit may comprises a light assembly that is disposed on the wearers side of the surgical garment, and an inner surface of said surgical garment may comprise a light reflective material configured to reduce the amount of light emitted from said light assembly that is reflected back toward the individual.

Embodiments of the present disclosure relate to helmet safety compliance systems for use in personal transportation ride-share systems. A rider safety compliance system, may include a personal transport upon which a user can be transported, a physical lock mechanism securely mounted on the personal transport and mechanically adapted to lock and secure a helmet, and a processor adapted to release the helmet from the physical lock mechanism as a pre-determined action for allowing the user to activate the personal transport.

A bicycle helmet that fits over a surface of a head of a user generally includes at least one segment of flexible cell structures that form a radial honeycomb matrix movable between a folded condition where each side of the at least one segment is disposed generally parallel and an expanded condition where the radial honeycomb matrix of the at least one segment is configured to be expanded at least partially over the head of the user and arranged radially relative to the surface of the head of the user.

A collapsible helmet for use in various athletic activities, and which includes a structure that facilitates collapsing the helmet into a compact position for storage and/or transport of same. The helmet includes an outer shell having an inner cavity, and one or more flexible sheets, each of which includes a center portion and a plurality of segments. The sheets are positioned in the inner cavity such that they are movable and slideable relative to the outer shell and each other so as to allow the helmet to be collapsed from an open position to a collapsed position.
