A fit adjustment system for a helmet is described.

An adjustment device of the position of a first part with respect to a second part, comprising an adjustment button mounted movable in translation inside a groove provided in the second part, and a blocking part having a locked position in which the blocking part prevents the first part from translating along the groove, and a locked position in which the blocking part enables the first part to translate along the groove, the adjustment button translating along the groove to move the blocking part to the unlocked position and to translate the first part along the groove.

A helmet which includes an impact absorbing liner and a comfort liner. The comfort liner in turn includes at least one adjustable device which during the normal use of the helmet is positioned on the top of the head of the user. The adjustable device is suitable for being fastened to the impact absorbing liner of the helmet by coupling suitable for being removably engaged on the impact absorbing liner of the helmet via a plurality of anchor points. By changing the anchor point where the adjustable device is engaged, the user is allowed to adjust the conformation and slope of the adjustable device of the helmet according to his own needs.

A headborne attachment platform includes multiple rigid plates and straps of connecting material connecting the rigid plates in an assembly at independently selectable and pre-set distances apart from each other. The assembly of rigid plates is shaped and connected to sit adjacent to, and surround, the bone regions of a wearer's skull, and define an overall headgear shape and contour. The straps are more flexible than the rigid plates in directions perpendicular to the thickness of the straps, and the straps are inelastic in a direction of a length thereof. A tightening mechanism is configured to adjust a circumference of a headband region, and the rigid plates have mounting features configured to mount an outer helmet shell and/or a headborne device. The rigid plates are sufficiently rigid to support and maintain their three-dimensional shape when subjected to forces exerted upon them by the outer helmet shell or headborne device.

Helmet comprising an outer shell having left and right side portions, inner padding configured to be located between the left and right side portions and a wearer's head, and a lateral adjustment device for adjusting the helmet's fit. The lateral adjustment device is between the outer shell and the inner padding and comprises a first leg with a distal end fixed to the outer shell or the inner padding; a second leg; a connecting leg portion interconnecting the first and second legs; a third leg with a distal end mounted to the second leg; and an actuator for moving the second leg between first and second positions with respect to the third leg while pivoting the connecting leg portion such that the first and second legs are movable from a first orientation to a second orientation. In the second orientation, the first and second legs lie in spaced planes.

A helmet harness with a lace tightening system is disclosed. The helmet harness is configured to be secured to the inside of a helmet shell. The harness includes a lace tensioning system and lace guides for distributing forces arising from tension in the laces to provide a secure and comfortable and adjustable fit. An inner frame and an outer frame are connected by cam slides at their extremities to even out tension applied circumferentially and tension applied over wearer's head, and to absorb rotational forces applied to a helmet shell in which the harness is secured.

An improved headband (12) for a head safety product such as a face shield, hardhat (10) or welding helmet includes a horizontal section (14) configured to encircle the head and an adjustment mechanism (14a) configured to adjust a circumference of the horizontal section. A nape-belt section (16) depends from the horizontal section (14) and is configured to cup the occipital area of the head and has a pivotal movement relative to the horizontal section (14). A flexible section (20) is connected between the horizontal section (14) and the nape-belt section (16). The flexible section (20) spring-biasing the pivotal movement of the nape-belt section (16) relative to the horizontal section (14).

The present application discloses a helmet, a helmet retention system, and a method of adjusting a helmet. In certain embodiments, the helmet comprises a helmet shell and a helmet retention system. The retention system comprises a rear portion connected to the rear of the helmet shell, first and second straps extending from the rear portion to a front portion of the helmet shell, and an adjustment device attached to the rear portion for adjusting the length of the first and second straps between the rear portion and the front portion of the helmet shell to tighten and loosen the straps about the head of the user. Each strap comprises a strap segment and an elongated member attached to the strap segment. The adjustment device is configured to selectively adjust the elongated member to move the first and second strap segments relative to the helmet shell.

The disclosure provides a ballistic helmet and a method of assembling a ballistic helmet that includes a helmet shell and a harness connected to the helmet shell. The helmet shell includes a front portion and a rear portion. The harness includes a nape pad, a tensioner disposed on the nape pad, a plurality of securement straps, and a tension cable. The plurality of securement straps are connected to the nape pad and are configured to fasten to the rear portion of the helmet shell. The tension cable is selectively adjustable by the tensioner and is configured to fasten to the front portion of the helmet shell.

A nape pad for use with a helmet, the nape pad comprising: a base comprised of a rigid material and having an outer surface and an inner surface, a left side and a right side, and a top edge and a bottom edge, the outer surface being generally convex from the left side to the right side and having an upper portion proximate the top edge and a lower portion proximate the bottom edge, the upper portion being generally smooth and configured to extend into and slide along an inner surface of the helmet, the inner surface of the base being generally concave from the left side to the right side; a fastener coupled to the lower portion of the base and configured to releasably couple to a retention system of the helmet; and at least one compressible comfort pad coupled to the inner surface of the base.
