Description

technical field [0001] The present invention generally relates to headgear structures and welding helmets, in particular auto-darkening welding helmets, equipped with such headgear structures. Background technique [0002] Head-mounted welding helmets currently employed in welding sites generally include a mask shell and a headgear structure secured within the mask shell. A protective sheet for protecting the operator's eyes is installed on the mask shell. A headgear structure is attached to the mask shell for wearing directly on the operator's head. [0003] The traditional headgear structure is made of plastic, which is in direct contact with the operator's head, making it uncomfortable to wear. In addition, when worn many times at the welding site, sweating can cause the headgear structure to accidentally slip on the head, resulting in loose fit or even personal injury due to accidental slipping that the protective sheet may not be able to provide protection for human e...
