A protective helmet has an outer shell configured for surrounding a head of a user and at least one accessory attachment rail connected to the outer shell. The accessory attachment rail has a body having a front end, a rear end, and one or more slots between the front end and the rear end. Each of the one or more slots is configured for removably receiving at least one helmet accessory. A locking mechanism is associated with each of the one or more slots for automatically locking the at least one helmet accessory in the one or more slots upon insertion of the at least one helmet accessory within the one or more slots and for preventing removal of the at least one helmet accessory from the one or more slots. At least one connection element is provided for connecting the accessory attachment rail to the outer shell.

Helmet with accessory attachment rail

A system for use in connection with a protective helmet having at least one accessory connection mechanism includes a visor accessory which includes a frame including at least one rearward extending member. The system further includes an adapter including a helmet connector adapted to form a releasable connection with the accessory connection mechanism of the protective helmet and an accessory connector adapted to form a releasable connection with the at least one rearward extending member of the visor accessory. The accessory connector is adapted to be stowed on the at least one rearward extending member when the adapter is not in use to connect to the accessory connection mechanism of the protective helmet.

An adjustment mechanism for a headband arrangement including a rotatable knob having a first contact member; a rotatable hub member to engage a notched track of a headband member; and a rotatable notched track member, wherein during contact between the first contact member and the hub member the rotatable notched track member does not rotate, and wherein during contact between a second contact member and the hub member the rotatable notched track member rotates in a second direction.

Adjustment mechanism for a headband arrangement of a safety helmet

An adjustment mechanism for a headband arrangement having a headband member with a notched track positioned on an end thereof, the adjustment mechanism including: a rotatable knob having a first contact member and a second contact member; and a rotatable hub member having a gear portion with teeth to engage the notched track of the headband member, such that rotation of the hub member in a first direction causes the headband member to tighten and rotation of the hub member in a second direction causes the headband member to loosen; wherein, upon rotation of the knob in the first direction, contact between the first contact member and the hub member causes the hub member to rotate in the first direction, and upon rotation of the knob in the second direction, contact between the second contact member and the hub member causes the hub member to rotate in the second direction.

A support system includes a headwear system, a frame adapted to have a visor attached thereto, a first member attached to the headwear system, a second member attached to the frame, which is pivotable relative to the first member, an adjustable mechanism adapted to abut and apply force to the second member in a first state to compress the second member into abutting engagement with the first member, an extending pivot member extending axially through a passage in the first member and a passage in the second member. The position of the adjustable mechanism is adjustable to place it in the first state or in at least a second, nonabutting state. The extending pivot member includes a first flange and a second flange, spaced from the first flange to capture a portion of the first member and a portion of the second member therebetween.

Support for visors and face shields

A protective helmet includes: a rigid shell including a generally domed-shaped section, a three attenuating liner within the dome-shaped section shell and operatively connected to the rigid shell; and a visor mount in operative connection with the force attenuating liner, the visor mount be adapted to have a visor mounted thereto.
