The present invention relates to a hard hat, comprising: a rigid outer shell, a vibration transducer secured to the exterior of the rigid outer shell, the vibration transducer operative to vibrate the rigid outer shell when active; and a control system coupled to the hard hat, the control system further operably coupled to the vibration transducer such that the control system controls vibration of the vibration transducer. The control system converts received audio communication into a signal sent to the vibration transducer such that activation of the vibration transducer results in vibration of the rigid outer shell, with the rigid outer shell thereby acting as a harmonic resonance acoustic chamber replicating the received audio communication. A kit for converting a hard hat and a method of communication are also disclosed.

A safety hat assembly for enhancing safety and comfort of a user includes a hat that is selectively sizable to a head of a user and which has a brim coupled thereto. The hat is positionable on the head of the user with the brim extending over a forehead of the user. A pair of safety glasses is slidably engaged to the hat and is selectively positionable in a stowed configuration within the hat and a deployed configuration to protect eyes of the user. An earplug is engaged to and selectively extendible from the hat to allow insertion into a respective ear canal of the user to protect hearing of the user. A set of pads is engaged to and positioned within the hat to cushion the head of the user.

A surgical garment for use with a helmet, wherein the garment comprises a shell, a transparent face shield, and an attachment element coupled to the transparent face shield. The garment may be configured to define a barrier between the wearer and the environment. The attachment element configured to removably couple with a coupling member of the helmet, wherein the attachment element and coupling member comprise complementary coupling surfaces. The attachment element comprises a head having a distal surface and a proximal surface, and defining a coupling recess, the coupling recess is defined in the proximal surface of the head. The garment may comprise a first and second attachment element, with the first attachment element being coupled to upper portion of the transparent face shield and the second attachment element being coupled to lower portion of the transparent face shield.

A hard hat attachment system is described with mounts to support various accessories. The hard hat includes various attachment points configured to receive adapters to couple to various accessories. The user customizes the hard hat for the particular task with the preferred accessories used to complete the job. For example, headlamps, face shields, earmuffs, sun shades, etc. are interchangeably releasably coupled to mounting and/or auxiliary ridges on the hard hat. In this way, the hard hat is customized and/or modified to support a wide variety of accessories that are securely and releasably attached to the hard hat without destructive alterations to the hard hat. Brackets couple to mounts and/or adapters couple to ports to support and/or secure various accessories in place during operation and prevent accidental knocks or jarring the accessory loose.

There is provided a novel aroma generator.

Provided is an aroma generator including: a cartridge holding unit equipped with a cartridge that holds a fragrance; and a control unit that automatically selects a type of the fragrance in the cartridge according to sensing information obtained from the outside. The sensing information may be external environment information and/or biological information. Furthermore, the aroma generator may further include an air blower that blows the fragrance in the cartridge, and the control unit may automatically change blowing intensity of the air blower according to the sensing information.

A comfortable construction helmet easy to assembly and adjust is revealed. The construction helmet includes a support frame mounted therein and a head cushion fixed on the support frame for allowing a user's forehead to abut against. Left and right straps are extended from two sides of the support frame while an adjustment assembly is disposed between the left and right straps for adjusting the length of the straps. The adjustment assembly includes a base, a rotating member mounted in the base, an outer cap, and a toothed disc arranged over the rotating member and positioned in the outer cap. Two connecting strip are extended from two sides of the rotating, member and connected to the left and right straps respectively. The toothed disc which is driven by the outer cap further drives the rotating member to rotate for changing the length of the connecting strips.

A shroud assembly for headgear includes a frame having a first side configured to face toward an exterior surface of the headgear and a second side opposite the first side and configured to face away from the headgear, the first side having a shape that matches a contour of the headgear. An insert separately formed from the frame is removably attached to the first side of the frame, the insert configured for removable attachment to a mounting assembly. The frame includes first and second spaced apart walls disposed on the front side of the frame on opposite sides of the insert, the first and second walls spaced a sufficient distance apart to provide an interference fit between the mounting assembly and the first and second spaced apart walls.

A brim shade has a shade element, a clip, and a hinge that joins the shade element and the clip to make the brim shade. The shade element and the hinge combine to create a shade that does not allow the light to get past the brim shade. The brim shade can be adjusted through 360 degree rotation and along the side of a hat to provide protection to the wearer.

A helmet including a protective head covering, information carrier, adhesive, and flap. The information carrier includes a first panel having a terminal edge, and a second panel having a fold line. The second panel is joined to the first panel to define a pouch having an interior space and an opening to the interior space. The opening is defined by the terminal edge disposed proximately to the first panel below the fold line. The adhesive is configured to affix the first panel to the exterior surface. The flap is pivotally attached to the second panel about the fold line, wherein the second panel is bendable away from the exterior surface at least between the terminal edge and the fold line to enable the flap to pivot about the fold line toward the exterior surface in connection with insertion of the flap into and removal of the flap from the opening.

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.
