A protective helmet has an outer shell, a protection shield movable relative to the outer shell between a deployed position and a stowed position, and a linkage mechanism for connecting the protection shield to the outer shell and permitting movement of the protection shield between the deployed and stowed positions. The linkage mechanism has a first link with a first end connected to the outer shell and a second end connected to the protection shield, a second link having a first end connected to the outer shell and a second end connected to the protection shield, and a biasing member having a first end connected to the first link and a second end connected to the second link. The second end of the biasing member moves between the first and second ends of the second link during movement of the protection shield between the deployed and stowed positions.

A helmet having a visor and a method of manufacturing such helmet are disclosed. The helmet comprises a shell dimensioned to receive the head of a user. A visor is moveably attached to the shell, and configurable between (1) a first position in which the visor extends from a forward region of the shell and (2) a second position in which the visor is substantially retracted with respect to the forward region of the shell. It is contemplated that actuation of the movement of the visor between the first position and the second position is automated on placement or removal of the helmet from the head of a user.

Glasses for a helmet is configured to rotate a glass member in a state where the glass member is mounted onto the helmet by means of one touch, thereby allowing the glass member to be located in front of a wearer's eyes, and configured to reversely rotate the glass member, thereby opening the front sides of his or her eyes. The glasses for a helmet includes: helmet attachment members fixedly attached to the helmet worn on a wearer's head; glass mounting members separably mounted onto the helmet attachment members by means of one touch; and a glass member adapted to rotate in a state of being rotatably fixed to the glass mounting members in such a manner as to be located in front of the wearer's eyes.

A skydiving helmet including a helmet shell having a front opening, is provided. The helmet further includes a visor having a lateral mounting section, where the visor is operable between a lowered position and a raised position. The skydiving helmet also includes a visor mounting system laterally positioned on the helmet shell to pivotally connect the lateral mounting section to the helmet shell. The visor mounting system includes a base plate having a cavity formed therein with a locking slot and a guiding section communicating with one another. The visor mounting system also includes a locking element positioned within the cavity and being operable between an extended configuration for preventing rotation of the visor, and a retracted configuration for allowing a frontward translation of the visor, away from the helmet front opening, and subsequent rotation of the visor, from the lowered to the raised position.

A visor locking mechanism is applied to a helmet equipped with a visor. The visor is provided on an inner side of an outer shell of the helmet which has a facial opening in a front side thereof. The visor is attached to a pair of left and right holders which are pivotably attached to the outer shell. The visor is configured to close or open at least part of the facial opening. A lock member that has an operation portion and a catch portion is disposed near at least one of the pair of holders. The operation portion allows the catch portion to fit together with or disengage from a catch counterpart portion provided at the pair of holders, whereby the visor becomes anchored or released.

A combination helmet and body protection device for use in contact sports and other activities requiring protection from force impacts is provided. The combination helmet and body protection device provides protection for the human body from potentially crippling forces applied to the head and upper body, comprising shoulder pad collar, a rear helmet portion, a main helmet portion, and a locking mechanism. The rear helmet portion is securely connected to the shoulder pad collar such that the rear helmet portion transfers impact forces inflicted along the helmet to the shoulder pad collar. The main helmet portion is rotatably connected to the rear helmet portion, allowing the main helmet portion to flip open along the rear helmet portion. The main helmet portion is also releasably connected to the shoulder pad collar through a locking mechanism, allowing the user to selectively position the main helmet between an open and a closed configuration.

Plural contact pieces of a shaft member, which is mounted to a helmet main body, abut a cam surface that is formed at a hole portion provided in a proximal end portion of a chin guard. When the chin guard is rotated from a fully closed position to a fully open position with respect to the helmet main body, at least one of the contact pieces abuts an anchor surface, and, simultaneously, at least another one contact piece fits into a concave portion, and, due thereto, the chin guard is fixed with respect to the helmet main body.

A helmet shield opening mechanism is provided, wherein first and second constraint tracks are provided on at least one support leg of a shield jaw guard, and a driver element is configured to come into contact with and drive the two tracks, so that the helmet has forced and controlled modes relative to the opening action and process of the helmet body. On one hand, the operational reliability and flexibility of the shield opening mechanism can be improved; on the other hand, the shield is opened smoothly without collision, thus improving the wearing comfort of the helmet. Further, a helmet with changeable jaw guard equipped with the helmet shield opening mechanism can plan the opening process of the shield flexibly to adapt to states of the jaw guard at different operation positions, thereby greatly reducing the chances of collision between the jaw guard and the shield.
