The present application relates to a headband arrangement comprising: an attachment structure; and a helmet mounting structure which can be selectively slid along the attachment structure, the helmet mounting structure having a lockable component, the lockable component being pivotable about a pivotal shaft between a locking position and an unlocking position, wherein a first magnetic part is secured in the lockable component, a second magnetic part is secured in the helmet mounting structure or the attachment structure, a repulsive force can be generated between the first and second magnetic parts to drive the lockable component to return from the unlocking position to the locking position and to hold the lockable component in the locking position. The present application also relates to a headband arrangement having a band part for attaching at or adjacent to the back of a user's head, wherein the band part is provided with a sheath for adjusting the band part's length, and a cushion structure is pivotally provided on a side of the sheath facing the back of the user's head. The present application further relates to a welding helmet having one of said headband arrangements.

An example head-worn device includes a camera, a display device, weld detection circuitry, and pixel data processing circuitry. The camera generates first pixel data from a field of view of the head-worn device. The display device displays second pixel data to a wearer of the head-worn device based on the first pixel data captured by the camera. The weld detection circuitry determines whether a welding arc is present and generates a control signal indicating a result of the determination. The pixel data processing circuitry processes the first pixel data captured by the camera to generate the second pixel data for display on the display device, where a mode of operation of said pixel data processing circuitry is selected from a plurality of modes based on said control signal.

A head suspension includes a headband portion having a length and two transition arms. Each transition arm is coupled to the headband portion and extends away from the headband portion length at an angle greater than zero degrees. Each transition arm has a distal end and a pivot at the distal end. The pivot characterized by a pivot point and a rear support portion is pivotally connected to each pivot.

In one aspect, a protective headwear is provided and includes a support member configured to engage a user's head, an outer shell coupled to the support member and rotatable relative to the support member between a first position and a second position, and a member coupled between the support member and the outer shell to reduce angular velocity of the outer shell as it moves from the first position to the second position. In one aspect, the protective headwear is a welding helmet.

A welding helmet (1) has a protective shield (2) and a first swivel mechanism (10) that pivotally connects the protective shield with a head suspension system (6) for swiveling about a swivel axis. The first swivel mechanism enables the protective shield and the head suspension system to be swiveled between a lowered position, in which the protective shield covers a wearer's face, and an upraised position, in which the protective shield uncovers the wearer's face. The first swivel mechanism (10) has a recess (16a) and a retainer (17a) for engaging with the recess. The retainer and the recess are arranged to engage with each other in the upraised position, and to remain disengaged in the lowered position and between the lowered position and the upraised position.
