A closure system for a boot or other footwear includes a tension member that is disposed within the boot and routed or guided about a path within the boot via one or more guides. The closure system also includes an adjustment member that is disposed within the boot and operably coupled with the tension member. The closure system further includes a reel based closure device having a knob that is operable to tension the tension member and to release tension from the tension member. Tensioning of the tension member adjusts a fit of the adjustment member about a foot within the boot to secure the foot within the boot and loosening of the tension member adjusts the fit of the adjustment member about the foot to allow the foot to be more easily removed from the boot.

A cowboy hat with interior head protection includes a hat, a helmet shell attached to the interior of the hat, and a ratchet adjustment assembly coupled to the helmet shell, wherein the helmet shell is substantially concealed within the interior of the hat.

The invention relates to a protective helmet (1) for the head (2) of a human being. Said protective helmet (1) comprises an outer protective shell (4) and an inner support structure (12) that includes a forehead strip (14) defining a head-accommodating opening (13) as well as a upper head support (15); on the forehead strip (14), the support structure (12) has a forehead-accommodating side (16) and a side (17) accommodating the back of the head; the support structure (12) is secured to the protective shell (4) using at least one force-transmitting connecting mechanism (18). A longitudinal adjusting mechanism (19) which is arranged between the protective shell (4) and the support structure (12) allows the protective shell (4) to be adjusted relative to the support structure (12) in the direction of the forehead-accommodating side (16) or in the direction of the side (17) accommodating the back of the head.

It is a typical harness conformed by a hard outer shell (1) that usually projects a front visor (2), and an optional crown with ventilation ports (3), enclosed in an inner harness (A) that lays on the wearer's head, keeping a considerable clearance in respect of the inner face of the shell (1). The helmet is put on the wearer's head and is positioned using an adjustable annular headband (4). The harness is a crowned thin structure conformed by curved portions of different width and equal thickness, which form stretching deformation portions based on the energy transferred during an impact. Thanks to the sizing of the curved portions that form the crowned structure, stretching deformation occurs at temperatures ranging from −18° C. to 50° C. The crowned structure is shaped from an upper elliptic portion (5) that delimits a vast upper and central opening (6) that is substantially elliptic, from which radial portions extend (7 and 8) until reaching a lower adjustable annular headband. This upper elliptic portion (5) presents two diametrically opposed stretched openings (9 and 10), through which it is subdivided in two internal curved portions of lesser width (11 and 12), opposed to the respective external curved portions, which are wider (13) and (14).

A face shield assembly including a chassis and a removable protective shield element supported by the chassis is disclosed herein. The chassis includes vertical returns to install accessories, as well as flexible portions to increase retention. The vertical returns mounted to the chassis include mounting points for the shield, and in some embodiments, the shield may slot into the chassis. In one embodiment, the frame is molded as a single, unitary member and in another it is molded from separate pieces which can be constructed into the complete chassis. Various shield embodiments are disclosed, including where the shield extends further toward a user's ears, but includes a taper to avoid contacting wearers shoulders.

The disclosed adjustable strap apparatus may include a left strap having a first rack member and a right strap having a second rack member. An electrical unit may have an opening through which a shaft passes. A pinion member may be affixed to a proximal end of the shaft and may be adapted to (a) engage the first rack member and the second rack member and (b) translate the first rack member and the second rack member in opposite directions via rotation of the shaft. A ratcheting member may be coupled to a distal end of the shaft and may include one or more pawls adapted to prevent rotation of the shaft when engaged. Various other methods, systems, and devices are also disclosed.

A surgical helmet assembly (30) to be worn by a user during surgical operations. The surgical helmet assembly includes a frame assembly (40) having a helmet shell (42) to be worn over the user's head. A fan (44) is coupled to the helmet shell to circulate air around the helmet shell. A headband assembly (78) is coupled to the helmet shell to secure the surgical helmet assembly to the head of the user. The surgical helmet assembly further includes an adjustment assembly (100) to adjust a sagittal fit of the helmet shell and the headband assembly to the head of the user while keeping a center of mass of the frame assembly in close proximity to the head of the user. The surgical helmet assembly further includes another adjustment assembly (118) concentric to the first adjustment assembly to adjust a circumferential fit of the headband assembly to the head of the user.

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.

Single-use, disposable helmets, hoods, and helmet/hood assemblies are disclosed. Methods of making and using single-use, disposable helmets, hoods, and helmet/hood assemblies are also disclosed.

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.
