Embodiments provide a retention apparatus for a head-mounted device and a head-mounted apparatus including the retention apparatus and the head-mounted device. The retention apparatus includes left and right band portions arranged on respective sides of a user's head, which connect to the head-mounted device at one end, and include opposing free ends that are arrangeable toward a back side of the wearer's head. The retention apparatus includes left and right elastic straps and an adjustment mechanism. The adjustment mechanism is arrangeable at the back of the user's head and includes arms the telescope into and out of the adjustment mechanism. The elastic straps are attached to the left and right band portions at first ends and to respective arms of the adjustment mechanism at second ends. Adjustably moving the arms of the adjustment mechanism stretches or relaxes the elastic straps, adjusting tension of the retention apparatus.

A helmet assembly comprising a helmet shell, a fit system detachably coupled to the helmet shell, and a retention system coupled to the helmet shell independent of the fit system. The fit system is configured to stabilize the helmet shell on the wearer's head. The retention system is configured to retain the helmet shell on the wearer's head and to stabilize the helmet shell on the wearer's head when the fit system is removed from the helmet shell. The retention system may include a stabilizer configured to extend in a circumferential direction about a rear portion of the wearer's head to stabilize the helmet shell on the wearer's head. The stabilizer may couple segments of the retention system together so as to restrict separation of the segments from each other.

A retention system for a helmet includes a horizontal chin strap and a vertical chin strap, wherein the vertical chin strap is secured to the horizontal chin strap at two points of intersection. The horizontal chin strap may include a first horizontal chin strap portion, a second horizontal chin strap portion, a first fastener for reversibly coupling the first chin strap and the second chin strap, and at least one mounting strap for affixing the mounting strap to a helmet. The vertical chin strap may include a second fastener for reversibly coupling a first end of the vertical chin strap to a body of the vertical chin strap, a loop through which the vertical chin strap passes through, and at least one forward strap for affixing the forward strap to a helmet.

The present application discloses a helmet, a retention system for a helmet, and a method of adjusting a helmet. In certain embodiments, the helmet comprises a helmet shell and a retention system attached to the helmet shell. The retention system generally comprises a rear portion connected to the rear of the helmet shell, at least one strap extending from the rear portion to a front portion of the helmet shell, and an adjustment device attached to the rear portion and configured to selectively adjust the length of the strap between the rear portion and the front portion of the helmet shell.

The present application provides a headband arrangement for a welding helmet, comprising: a fixed attachment structure; and a helmet mounting structure cooperating with the attachment structure, wherein at least two stopping positions are defined longitudinally between the attachment structure and the helmet mounting structure, the helmet mounting structure is selectively switchable between an unlocking state and a locking state, wherein in the unlocking state, the helmet mounting structure is slidable between the stopping positions relative to the attachment structure, and wherein in the locking state, the helmet mounting structure can be locked to one of the stopping positions relative to the attachment structure and can be kept there by a magnetic force generated between a pair of magnetic parts.

A head-mounted display system includes a head-mounted display unit and a positioning and stabilising structure structured and arranged to hold the head-mounted display unit in an operational position over a user's face in use. The positioning and stabilising structure includes a rear support structure adapted to contact posterior regions of a user's head and at least one connector structured and arranged to interconnect the rear support structure to the head-mounted display unit. The rear support structure is in the form of a hoop comprising an occipital portion configured and arranged engage the user's head along a portion of the occipital bone adjacent a junction where the neck muscles attach to the occipital bone in use.

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.
