A personal protection system for providing a sterile barrier around medical/surgical personnel. The system may include a head unit over which surgical garment such as a hood or a toga may be suspended over. The surgical garment may include a sterile material and a shield configured to be disposed in front of the wearers face when disposed over the head unit. The shield may comprise an anti-reflective coating configured to reduce the glare observed by the individual through said shield. The head unit may comprises a light assembly that is disposed on the wearers side of the surgical garment, and an inner surface of said surgical garment may comprise a light reflective material configured to reduce the amount of light emitted from said light assembly that is reflected back toward the individual.

A helmet comprising one or more additively-manufactured components designed to enhance performance and use of the helmet, such as: impact protection, including for managing different types of impacts; fit and comfort; adjustability; and/or other aspects of the helmet. Methods of additively-manufacturing components for such helmets are also provided, including methods involving expandable materials and the expansion of post-additively manufactured expandable components.

A bicycle helmet that fits over a surface of a head of a user generally includes at least one segment of flexible cell structures that form a radial honeycomb matrix movable between a folded condition where each side of the at least one segment is disposed generally parallel and an expanded condition where the radial honeycomb matrix of the at least one segment is configured to be expanded at least partially over the head of the user and arranged radially relative to the surface of the head of the user.

A helmet can include an upper body comprising an interior surface comprising a locking flange, and a lower body positioned at least partially inside the upper body. The lower body can comprise an edge in contact with the locking flange of the upper body. At least one joining pin can be located within, and bridge, the lower body and the upper body. An at least one basket pair can comprise an upper basket comprising a pin receiver, the upper basket being at least partially embedded within the upper body. A lower basket can comprise a pin aperture, the lower basket being at least partially embedded within the lower body and positioned such that the pin aperture is aligned with the pin receiver of the basket pair. The at least one joining pin can be positioned inside both the pin aperture and the pin receiver of the basket pair.

A helmet assembly may include a helmet and an integrated chinbar. The chinbar may include an attachment portion and the helmet may include a docking frame. Coupling together of the attachment portion to the docking frame may couple the chinbar to the helmet. The attachment portion may then be secured to docking frame to secure the chinbar to the helmet. In certain embodiments, the attachment portion may be coupled to the docking frame of an interior side of the liner. Thus, the attachment portion may accordingly be disposed on the side of the liner closer to a wearer's face.

An impact resistance spreading helmet is disclosed. The helmet includes a frontal section configured to interface with the forehead of an individual and extend upward over the cranium; a medial section for extending over a portion of the cranium rearward of the frontal section; an occipital section for extending rearward from the medial section and configured to cover a portion of the neck of the individual; a first compressible structure disposed between the frontal section and the medial section; and a second compressible structure disposed between the medial section and the occipital section. The interface between the frontal section and the first compressible structure is disposed at an angle vertical to a force direction perpendicular to the frontal section above the forehead of the individual.

A protective helmet including a helmet body, a facemask extending from the front portion to cover at least a portion of a face of a wearer, and one or more adjustment mechanisms securing the facemask to the helmet body. The adjustment mechanism(s) is/are connected to the helmet, include(s) an engagement member engaged with the facemask, is/are selectively engageable with the facemask in at least two vertically spaced apart positions of the facemask relative to the helmet body, and allow(s) toolless adjustment between the vertically spaced apart positions. Adjustment mechanisms and methods of positioning a facemask are also discussed.

In this publication is described a traditional forest helmet visor (1), plus in accordance with the invention a lightweight and ventilated plastic frame-body (3) that is connected to downparts of the visor (1) and a fabric-curtain (2) fastened into the inner circle of the framebody (3). The true function of the framebody (3) is to position a lightweight and elastic fabric-curtain (2) to an optimal location near the upper part of neck. For setting work mode the backsides of the framebody (3) can be connected either to the hearing protector structure or those can be connected together by express hooks being in each other's endparts. With these solutions the fabric-curtain (2) can be positioned as aimed broadly round the circle of the upper neck. As a result the fabric-curtain (2) is properly interlaced and efficiently supplyes protection for the bare nec and face areas together with the current workwear. Due to the protection a general mobility in brushwoods is getting simpler and that equally enables a rise in working performance. The improved mobility is quite an advantage specially in clearingsaw-work, because it as a workform requires more motion just among branches. In addition the hearing protectors can be equipped with quite a familiar fabric-curtains and hangers as well. In the combimodell the backsides of the framebody (3) can be sized significantly shorter (21) accordingly and there is no purpose for any fastening elements for work mode.
