A motorcycle helmet, having a helmet shell, a chin part for covering a chin portion of a wearer, and a visor, uses a coupling mechanism by means of which the chin part is fastened to the helmet shell and pivotable between a lower position and an upper position. With the chin part in the lower position, by means of the coupling mechanism, the visor can assume a respective pivoting position between a closed position and an open position. The coupling mechanism is further designed, upon pivoting of the chin part from the upper position into the lower position after the chin part has previously been pivoted from the lower position into the upper position, to cause the visor to occupy a pre-pivoting position differing from the closed position, which pre-pivoting position the visor occupied before the pivoting of the chin part from the lower position into the upper position.

A helmet slide assembly is attached to a helmet and functioning to enable a tilting of a visor relative to the helmet. The helmet assembly includes a base plate that is attached to a sidewall of the helmet and a slide plate disposed substantially in a parallel arrangement relative to the base plate and secured to a sidewall of the visor. The slide plate has an elongated slot for receiving a pivot member. The assembly also includes a pivot plate having locked and unlocked positions. The pivot member is secured at one end thereof to the pivot plate and the slide plate is constructed and arranged for a sliding motion once the pivot plate is unlocked.

The invention belongs to the technical field of helmets and relates to a helmet with a transformable jaw protecting structure, wherein a jaw protector is reliably transformed between a full-face helmet position and a half-face helmet position in a gear constraint structure and mode, and the uniqueness and reversibility of a kinematical and geometrical locus of the jaw protector can be kept everywhere during a round trip. The helmet according to the invention has the greatest advantages that: the integrity of a whole structure of the mount and the jaw protector can be kept while implementing a transformable jaw protecting structure of the helmet in the meanwhile, thus ensuring that these core members have higher intensity and rigidity, and effectively enhancing the use safety of the helmet; in addition, an exposed slit may be dramatically reduced or even completely eliminated, buzzing noises derived by flowing an air current through a helmet housing surface and rainwater invasion may be significantly reduced, and a wearing comfort of the helmet is effectively improved; and besides, the difficulty in assembling the mount and the jaw protector is reduced and a precise gear engagement and constraint structure is adopted, so that the quality reliability of a helmet product can be effectively improved.

A helmet can include a protective shell and a layer of energy management material coupled to an inner surface of the protective shell to form a cavity for receiving a head of a user. An earpad can be coupled to the inner surface of the protective shell that comprises an inner surface that further defines a space for an ear of a user. The earpad can further include a leading edge at a front of the helmet, the leading edge extending between the outer surface of the protective shell and the inner surface of the earpad. An air intake opening can be formed at the leading edge of the earpad. An air exhaust opening can be formed at a trailing edge of the earpad. An airflow channel can extend through the earpad between the air intake opening and the air exhaust opening.

A shower helmet device with a moveable face guard includes a removably attached curvilineal deflector, a cranium cradle attachable to the moveable face guard and has a cranium cushion arranged within a cranium cradle interior. In various embodiments a cervical spine support and a cradle positioner provide additional stability for a user. The shower helmet device provides a relaxing, refreshing, and visually stimulating user experience while showering.

Devices, systems, and methods, etc., that provide, in certain aspects, a two-point, adjustable, partially pliable, and releasable tensioning suspension that supports an anti-blunt-force frame connected to a protective helmet. The protective devices herein can be, for example, sport-level and military/law enforcement-level. The anti-blunt-force frame is positioned and balanced on the wearer's face by an impact absorbing face padding system, including a chin strap, cup or pad comprised of an impact protection material. Thus, in one aspect, the present devices, systems, methods, etc., include an adjustable facial protection system for a human comprising a crescent-shaped face protection element configured to withstand blunt force impact and a ballistic material element to prevent the penetration of ballistic and fragmentation projectiles at various force levels to meet different ballistic hazards. The systems can also include a protective helmet.

A protective helmet having multiple protective zones, including an inner shell having a first inner surface and a first outer surface, a padded inner lining attached to the first inner surface, an outer shell having a second inner surface and a second outer surface, the outer shell functionally attached to the inner shell, an elastomeric zone between the first outer surface and the second inner surface, a plurality of energy dissipation devices arranged between the inner and outer shells, and a plurality of sinusoidal springs positioned in the elastomeric zone. Each of the plurality of sinusoidal springs includes a first end, and a second end connected to one of the plurality of energy dissipation devices.

IMPROVEMENTS INTRODUCED IN A CRANIAL PROTECTION CELL, formed by an outer shell (11, 20) internally coated by absorbent material (12, 12), said material comprising a first layer (21) immediately below the shell, of closed cell foam, rigid or semi-rigid in contact with a second layer (22) of open cell viscoelastic foam, the interface between said first and second layers being provided with interdigitations comprising cavities (24) in said first layer in which protrusions (23), provided in said second layer, fit in a complementary and cooperative manner. Absorbent supporting material are further provided in the jaw region (32), maxillary regions (33, 34) and mastoid regions. When closed, the visor (37) is embedded in the corresponding opening of the cranial protection cell, and its opening occurs in two steps, the former comprising forward movement, and the latter upward rotation. The cranial protection cell (CPC) further comprises a removable chin guard (54) whose unlocking mechanism is driven by buttons (51) located on either side of the shell.

A helmet according to the present invention includes: a head frame being open toward the user's face, designed to cover the user's head, and having a rotation part at both sides; a face frame coupled to be turned up and down about the rotation parts and selectively closing the opening of the head frame; and a sun visor disposed at an upper portion of the face frame and coupled to be turned up and down about the rotation parts, in which the sun visor is turned up with the face frame when the face frame is turned up to open the opening of the head frame, and is fixed regardless of rotation of the face frame when a predetermined rotational limit is reached.
