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.

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 hinge mechanism for attaching ear accessories to a helmet allows an accessory to be attached at a point outside the helmet shell utilizing, for example, a slidable mounting rail, and to reach under the edge of the helmet shell so that the accessory is supported in contact with the wearer's head. The hinge mechanism is well suited for use in connection with military helmets that have a “bulge” or protrusion over the ear.

A connecting apparatus detachably connects two assemblies. The connecting apparatus includes a fastener module securable to a first of the assemblies and including a negative-pressure element, and an attachment component of a second of the assemblies. The negative-pressure element is connectable in an attachment direction to the attachment component for connecting the assemblies with one another, wherein, in a connected position, the negative-pressure element interacts with the attachment component such that, in the event of a load acting in between the fastener module and the attachment component opposite to the attachment direction, the negative-pressure element and the attachment component are held against one another by a negative pressure acting between the negative-pressure element and the attachment component. The fastener module includes an adjustment element which is adjustable relative to the negative-pressure element and which is movable relative to the negative-pressure element.

A modular helmet interface with a mounting cleat, threaded insert, and adhesive layer is provided. In one aspect, a mounting cleat is affixed to a helmet, such as a ballistic helmet, by an adhesive layer, the mounting cleat having an outer portion and a threaded insert within a cavity formed in the outer portion. The outer portion has an inward facing surface configured to receive an adhesive layer for coupling the inward facing surface to the helmet surface. In another aspect, a mounting cleat is secured to a helmet by way of a cleat-receiving securing member, the securing member affixed to the helmet by an adhesive layer. In a more limited aspect, a helmet having multiple mounting cleats configured to support an accessory mounting rail or a helmet mount assembly.

A helmet comprising: inner and outer shells configured to slide relative to each other; and a connector connecting the inner and outer shells so as to allow the inner and the outer shells to slide relative to each other, the connector comprising: an attachment part attached to one of the inner shell and the outer shell; wherein: the attachment part comprises one or more protrusions and the inner or outer shell attached to the attachment part comprises one or more channels into which the protrusions extend, the protrusions and channels are configured such that the protrusions can move within the channels in an extension direction of the protrusions, during sliding of the inner and outer shells relative to each other, and the protrusions comprise an abutment member configured to abut an abutment portion of the channel to prevent the protrusion leaving the channel.

The present disclosure describes clips for lanyards, such as hard hat lanyards. The clips include opposing teeth that move to a closed/clamped position to secure a lanyard to a user, such as to the clothes of a user. The clip includes a body, a lever and a grip. Opposing teeth are located on the grip and body. The clip includes multiple pivoting connections between the body, lever and grip. The teeth on the grip may lie along an arcuate path and/or may have a tooth depth that facilitates engagement with material such as clothing.

A hinge mechanism for attaching ear accessories to a helmet allows an accessory to be attached at a point outside the helmet shell utilizing, for example, a slidable mounting rail, and to reach under the edge of the helmet shell so that the accessory is supported in contact with the wearer's head. The hinge mechanism is well suited for use in connection with military helmets that have a “bulge” or protrusion over the ear.

A mounting device having a mounting assembly for mounting a pair of goggles to a helmet is provided. The mounting assembly is configured to provide at least three degrees of freedom of movement using one or more actuation mechanisms for locking and unlocking a position of the mounting device. The number of actuation mechanisms is less than a number of degrees of freedom. In some aspects, the number of actuation mechanisms is one. A rotation base connects the mounting assembly to the helmet, and a goggle linkage connects the mounting assembly to the goggles. Various single actuation mechanisms, including a sliding mechanism, a friction-based wire/brake mechanism, and a floating friction brake mechanism, are provided.

A multiple component system is provided for mounting on a safety helmet and includes a first component housing carrying a first component, and a second component housing carrying a second component. Each housing has a first mount connector and a second mount connector located on opposing faces of the housing. The first mount connectors are configured to be compatible with the second mount connectors to provide quick release mount connections between the housings.
