Abstract: An eyewear assembly has a frame with removable lenses. The eyewear assembly may include upper and lower frame portions that are separable from one another at a bridge region of the frame using a linkage. A finger actuator actuates the linkage to cause the upper frame to move away from the lower frame, exposing at least one edge of the lenses for removal. The separated upper frame portion and lower frame portion may be held in a stable open position. After lens removal or replacement, the linkage may be actuated to reconnect the upper frame portion and lower frame portion, thereby enclosing the lenses.

Abstract: A helmet accessory attachment member includes a finger-actuatable lock configured to secure an accessory attachment member mount to a helmet mount as part of securing an accessory such as a mandible guard to a helmet. The lock includes a pivot arm with a rotation axis that is parallel to the helmet surface, and also includes one or more blocking surfaces on the pivot arm to engage with grooves on the helmet mount. The lock may be positioned on a slidable insert of the accessory attachment member.

Abstract: A protective helmet adapted to receive and protect a head of a wearer comprises: an outer shell shaped to protect the head of the wearer, with the outer shell defining a bottom opening and an internal cavity for receiving the head of the wearer; a headband and a suspension positioned within the internal cavity of the outer shell; and a visor rotatable between a retracted position within the outer shell to an extended position in front of a face of the wearer, wherein the visor simultaneously rotates about a first pivot axis and a second pivot axis as it moves between the retracted position and the extended position. The visor can also be readily removed from the protective helmet and easily replaced should it become damaged.

Abstract: 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.

Abstract: A visor assembly for a helmet including two adjustment mechanisms each including a base portion connectable to a side portion of the helmet and a cover portion. The base portion has an adjustment aperture and at least one support member. The cover portion of each adjustment mechanism is manually displaceable between a secured position engaged with the base portion and an exposed position. The cover portion allows access to the adjustment aperture(s) in the exposed position. The support member(s) of each adjustment mechanism are removably engaged to the respective side end portion of the visor. In the secured position, the cover portion prevents disengagement of the support member(s) from the visor. A method of adjusting the position of the visor is also disclosed.

Abstract: A cord tensioning device has three modes of operation: a tightening mode, a release to loosen and then hold mode, and a release mode for relieving all tension in the cord. In the tightening mode, the shape of ratchet pawls and ratchet teeth allow a cord winding spool to rotate in only a tightening direction. In the release to loosen and then hold mode, an actuator associated with the knob releases the ratchet pawl from the ratchet teeth in a reverse direction, but upon release of the knob, the pawl re-engages the ratchet teeth to prevent further loosening. In this manner, the tension can be incrementally loosened. In the release mode, the pawls are disengaged from the ratchet teeth, even after release of the knob, and the spool can continue to rotate within the base when an external tension is applied to the cord.
