A protective component for a helmet includes a liner or shell that is coupleable with the helmet so that the liner or shell is positioned on an interior surface of the helmet. The liner or shell is made of a low-friction material and is coupled with the helmet so that the liner or shell is moveable relative to the helmet in response to a force being exerted on the helmet. A rear support member is removably coupled with the liner or shell and a tightening mechanism is attached to the rear support member. The tightening mechanism is configured to tension a tension member and thereby tighten the liner or shell, and the helmet, about the wearer's head.

An interface system for a helmet mounting system comprises a helmet strap assembly. A helmet shroud includes a shroud interface assembly configured to mate with a first hot shoe of a helmet mount assembly. The shroud interface assembly comprises a high speed data interface configured to be electrically coupled to the first hot shoe when the shroud interface assembly is coupled with the first hot shoe. A battery mount assembly comprises a second hot shoe portion which is configured to mate with a hot shoe receiver of a battery pack. The second hot shoe portion comprises a high speed data interface which is configured to be electrically coupled to high speed contacts on the hot shoe receiver of the battery pack when the second hot shoe portion is coupled with the hot shoe receiver of a battery pack.

A safety helmet and accessory system for construction worksites. The system includes a safety helmet that defines two apertures, each aperture being positioned on the helmet so that they will correspond to a user's left and right ears when the safety helmet is placed on the user's head, the safety helmet has a plurality of cord holder attachments attached within an inner circumference of the safety helmet. A pair of capsules, each capsule is secured within each aperture of the safety helmet. A cord that has two terminal ends and each terminal end has a securing device. And, a pair of earplugs that define a stem, the stem of each ear plug has a receiver that receives each securing device. The system provides a safety helmet that has an integral earplug securing system.

Various embodiments of safety headwear are provided. The safety headwear includes one or more of a hard hat, such as a safety helmet, and a respirator. The safety headwear monitors one or more conditions, such as biometric and/or atmospheric conditions. The safety headwear analyzes the results of the monitoring to determine whether to generate an alarm to the wearer of the safety headwear.

A helmet that includes vents in the shell and removable plugs that may be positioned in the vents to provide an airtight seal while maintaining the aerodynamic shape of the helmet. The vent has an outer vent opening in the outer wall surface of the shell and an inner vent opening in the inner wall surface of the shell. The plug includes a resilient lower surface and an upper surface opposite the resilient lower surface. The resilient lower surface has a lower peripheral lip that compresses when the plug is pushed through the outer vent opening and the inner vent opening and that subsequently expands after the lower peripheral lip passes through the inner vent opening so that the lower peripheral lip engages a portion of the inner wall surface of the shell. The upper surface has an upper peripheral lip configured to conform to a portion of the outer wall surface of the shell when the plug is inserted in the vent.

The present specification discloses systems, devices, and methods and uses provide a mounting system which includes rail and a bracket which is selectively secured to the rail. A bracket disclosed herein selectively and/or automatically secures or locks to a rail disclosed herein when positioned on the rail by actuating or triggering a locking mechanism disclosed herein to adopted a locked configuration. In addition, a bracket disclosed herein may be selectively removed from a rail by actuating or triggering a locking mechanism disclosed herein to adopted an unlocked configuration. The disclosed mounting systems, devices, and methods enable a device to be protected from impact and moisture exposure, enable a device to be securely mounted on a base, and/or enable a device to be quickly secured and removed from a base.

A protective suit comprising: a head portion comprising a fluid-filled head portion chamber; a neck portion releasably secured to the head portion and comprising a neck portion chamber, wherein the fluid-filled head portion chamber is in fluid communication with the neck portion chamber; and a torso portion releasably secured to the neck portion and comprising a fluid-filled torso portion chamber, wherein the fluid-filled torso portion chamber is in fluid communication with the neck portion chamber; and wherein the head portion is configured to be disposed on a head of the wearer, the neck portion is configured to be disposed in an arcuate manner around a neck of the wearer, and the torso portion is configured to be disposed on a torso of the wearer, such that when a force of an impact is received on the head portion, fluid from the fluid-filled head portion chamber is transferred into the neck portion chamber to support the neck of the wearer against translational and rotational forces imparted to the wearer, and when a force of an impact is received on the torso portion, fluid from the fluid-filled torso portion chamber is transferred to the neck portion chamber to support the neck of the wearer against translational and rotational forces imparted to the wearer.

A novel viewing device mount includes a base and a first articulating arm. The first articulating arm includes a proximal end movably coupled to the base and a distal end configured to couple an optical device to the first articulating arm. The articulating arm further includes a first joint and a second joint. The first joint facilitates angular displacement of the optical axis of the optical device and the second joint facilitates translational displacement of the optical axis of the optical device. In a more particular embodiment, the viewing device further includes a second articulating arm having a proximal end coupled to the base and a distal end configured to couple a second optical device to the second articulating arm. In another particular embodiment, the base is configured to be removably attached to a head worn device such as, for example, a combat helmet.
