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 upraisedposition, 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. 本发明提供了一种焊接头盔(1)，所述焊接头盔具有保护罩(2)和第一旋转机构(10)，所述第一旋转机构将所述保护罩与头部悬置系统(6)枢转地连接以围绕旋转轴线旋转。第一旋转机构使保护罩和头部悬置系统在降低位置和升高位置之间旋转，在降低位置，保护罩覆盖佩戴者的面部，在升高位置，保护罩露出佩戴者的面部。所述第一旋转机构(10)具有凹部(16a)和用于与所述凹部接合的保持器(17a)。保持器和凹部被布置为在升高位置彼此接合，并且在降低位置以及在降低位置与升高位置之间保持分离。
